PsychologyPh.D.
Currently, two-thirds of adults and one-half of children and adolescents in the United States meet criteria for overweight or obese weight status (Wang & Beydoun, 2007). While weight loss often is desired among these individuals, few achieve sustained weight loss maintenance. A model of motivation, affect, and long-term weight loss maintenance is proposed, based on Carver's model of behavior change (2004b) and related research. This investigation evaluated the model's proposed associations between approach and avoidance motivation, depressive and anxious affect, and caloric consumption within the context of a dietary lapse condition in the laboratory. Findings did not support the hypotheses that avoidance motivation would be negatively related to calorie consumption or that approach motivation would be positively associated with calorie consumption. Conversely, higher avoidance motivation was found to predict higher caloric consumption. Finally, this relationship was not mediated by depressive or anxious affect. Instead, consumption of high calorie foods alone was shown to fully mediate this relationship. Recommendations for future research are presented in the context of these findings.

Full textAbstract:
Obesity is one of the most serious health problems facing modern society and strategies to address this pandemic have so far been ineffective. Although weight loss (WL) is achievable, prevention of weight regain is a major challenge. The overall aim of this thesis was to identify predictors of WL and weight loss maintenance (WLM) to promote better tailored and sustainable interventions. A systematic review evaluated the evidence from 80 studies examining predictors of WL and/or WLM in behavioural and/or dietary WL interventions (with or without exercise) in overweight and obese individuals. Aside from physiological factors such as initial weight loss, a number of personal characteristics broadly conceptualised as reflecting affective, cognitive, behavioural and motivational factors were acknowledged as potential predictors of WL and/or WLM. Affective (e.g. anxiety), behavioural (e.g. eating behaviour, self-monitoring, social support, physical activity, treatment adherence, previous WL attempts) and motivational factors (e.g. self-efficacy) were the strongest predictors identified. Study 1 assessed predictors of WL and WLM in free-living participants (N=71) who received healthy eating advice with (HE+F) or without (HE) advice to increase dietary fibre. Predictors of WL were age, body weight and body image at baseline (affective), fasting plasma leptin and disinhibition (behavioural) with some differences according to diet group. These also predicted WLM at 1 month follow-up. At 12 month follow-up, having a higher body weight at week 12 and greater depression (affective) at follow-up were associated with greater weight regain. Additionally, having stronger beliefs that medical reasons cause obesity (cognitive) and less stressful life events (affective) were associated with better WLM. Study 2 utilised an online survey and cluster analysis to examine affective, cognitive, behavioural and motivational factors in a real world setting with individuals (N=314), who had previously attempted to lose weight using different WL methods. Two distinct clusters were identified: less successful (Cluster 1) and more successful (Cluster 2). Cluster 2 was associated with lower emotional and external eating, lower disinhibition and higher restraint (behavioural), less depression, anxiety and stress (affective), and significantly higher diet satisfaction, eating self-efficacy (motivational) than Cluster 1. Study 3 examined predictors of WL in an NHS delivered 12 week community based weight management programme (N=22). Higher diet satisfaction, an improvement in body image and higher baseline body weight were significant predictors of WL. Based on the evidence presented in this thesis, there are clear personal characteristics which promote and sustain obesity. WL and WLM is clearly not just a problem of appetite control. Affective (stressful life events, body image, diet satisfaction and depression), behavioural (eating behaviour) and motivational factors (self-efficacy and motivation) were the most consistent psychological predictors of WL and/or WLM across all studies. Interventions should therefore target these personal characteristics in order to promote WL and prevent weight regain. The paucity of studies incorporating long-term follow-up shows that further research is needed to examine the role of affect, cognition, behaviour and motivation in the long term. A multidisciplinary approach to tackle obesity, which addresses psychological, social, environmental, and biological factors is essential to ensure comprehensive care, best practice and outcomes.

Full textAbstract:
This thesis investigates the acceptability and efficacy of Functional Imagery Training (FIT), a motivational intervention for weight-management. FIT is based on Elaborated Intrusion Theory, delivered in the style of Motivational interviewing (MI), and designed to promote sustained behaviour change and address cravings. It trains the habitual use of affective, goal-directed mental imagery of personal incentives, using imagery to plan behaviours, anticipate obstacles, and mentally try out solutions from previous successes. Participants are taught to update their imagery from their experience, and to generalise their imagery skills to new goals. In study 1, focus groups explored problems and wishes in regards to weight-management, including reactions to Functional Imagery Training (FIT) as a possible intervention. The issue of waning motivation and the desire for motivational app support was expressed in all groups. Participants were positive about FIT. Study 2 was an uncontrolled pilot trial of FIT. Eleven out of 17 participants (65%) lost 5% body weight or more by three months. Participants continued to lose weight during an unsupported 12-month period and experienced mean weight loss of 6kg (SD= 5.7; d=1.06) and mean waistline reduction of 11.5 cm (SD= 7.4; d=1.56) at 15 months. Study 3 compared the impact of FIT with MI on motivation and self-efficacy, over the first month of a randomised controlled trial (RCT) for weight-loss. Structured elicitation and training in goal-related imagery, i.e., FIT, increased motivation and self-efficacy for weight-loss relative to MI. Study 4 was the RCT for weight-loss, comparing FIT and MI over an intervention-supported six-month period, followed by six months unsupported. The FIT group achieved clinically meaningful weight-loss at 6 months (M kg-loss=4.11) and continued weight-loss at 12 months (M kg-loss=6.44); the MI group stabilised by 12 months (M kg-loss=.67), after minimal weight loss at 6 months (M kg-loss=.74). Study 5 qualitatively explored experiences of MI and FIT RCT participants, upon completing the 6-month intervention phase. MI participants wished for continued therapist- support and feared relapse. FIT participants described a mind-set-change and were confident they could maintain changes and overcome challenges using imagery techniques. Given the demonstrated benefit of motivational imagery in weight-control, FIT should be considered and further tested as an intervention for health behaviour change.

En del personer med övervikt vill gå ner i vikt, men det kan vara svårt att lyckas. Studiens syfte var att ta reda på deltagares upplevelse av sin viktminskning på Itrim. En kvalitativ studie med 9 personer, varav 7 kvinnor som deltagit i Itrims viktminskningsprogram intervjuades och datamaterialet analyserades genom meningskoncentrering. Enligt motivationsteorin Self-Determination Theory (SDT) så ökar sannolikheten för att beteendeförändringar blir bestående om de är autonoma och motivationen intern. Resultatet visade att deltagarna upplevde sin viktminskning som positiv och att Itrims koncept fungerar bra. Deltagarna motiverades genom olika uppsatta mål, använde sig av olika strategier och upplevde ett bra stöd. Genom att gå på ett viktminskningsprogram känner personerna en stark samhörighet och ser sig själva som en del av en helhet. De känner sig inte ensamma i sin situation. Svårast är beteendeförändringen då den tar tid och kräver energi, men till hjälp använder deltagarna egna personliga strategier.

Full textAbstract:
Objective: To determine the extent to which coaching over the telephone is an effective method in promoting the loss of body weight and body fat percentage. Research Methods and Procedures: Over a period of four months, in a randomized, double blind, placebo-controlled study, 120 overweight and obese (BMI 25-35 kg/m²) adults either received telephone coaching or no coaching. In addition, each participant was randomly assigned to take a supplement or placebo daily. Body weight and body fat percentage were measured at baseline, two months, and four months. Body weight was measured on an electronic scale and body fat percentage was assessed using dual energy x-ray absorptiometry (DEXA). Participants in the coaching group each received a minimum of 10 coaching sessions, each at least one week apart. Age, gender, and supplement use were controlled statistically using partial correlation. Results: When using repeated measures ANOVA, telephone coaching had a significant and favorable effect on body weight loss over the three time periods when compared to participants who received no coaching (F = 3.9, p = 0.0216). Also, when weight changes from baseline to four months were compared, ignoring the two-month time period, those in the coaching group lost significantly more weight than their counterparts (F = 4.75, p = 0.0315). When weight changes from baseline were compared to the halfway mark (two months), telephone coaching resulted in significantly greater weight loss at the trend level (F = 3.42, p = 0.0671). However, during the second half of the study (two months compared to four months), the effect of coaching was weaker and non-significant. Controlling statistically for age, gender, and supplement use, individually and collectively, had no effect on the impact coaching had on body weight loss. Telephone coaching did not play a significant role in helping participants lose body fat percentage across the three time periods compared to those who received no coaching (F = 1.28, p = 0.2797). Similarly, baseline body fat percentage means contrasted with four-month means (F = 1.65, p = 0.2018) were not significant, and findings from the two halves of the study showed that telephone coaching did not have a significant effect on the loss of body fat percentage. Discussion: Telephone coaching is an effective and inexpensive method of helping overweight and obese adults lose body weight, but not body fat percentage, over a four-month period.

Full textAbstract:
Almost half of Americans between 17 and 24 years of age are enrolled in higher education. College is an important life transition period when many young adults establish independence and adopt lasting behavior patterns, especially with regard to diet and physical activity. The first years of college are often associated with weight gain therefore making weight loss and weight gain prevention interventions necessary in this population. Behavioral weight loss programs (BWLP) have shown to be effective in adults, however, to our knowledge, there have been no reports of BWLP focused solely on college-aged young adults. This study compared a 10-week online behavioral weight loss program to a 10-week face-to-face program on the main outcomes of weight loss, change in body fat percentage, and change in physical activity among college students. Correlates of weight loss including self-monitoring, social support, attendance, selfefficacy, and motivation were also examined. Results showed motivation decreased over time, motivation was positively correlated with weight loss, and self- efficacy increased over time.

Full textAbstract:
Aim: The present study aimed to investigate psychological influences upon overweight and obese eight to twelve year aids weight loss success in a resistance training program.
Design: A mixed method repeated measures design was used. The quantitative component involved participants' completing self-report questionnaires on conditional goal setting, motivation, depression and self-concept at pre-test, post-test and at an eight week follow-up. Body composition data was collected at the same time periods using Dual X-Ray Absorptiometry. The qualitative component involved a small group of participants' participating in two semi-structured interviews, one early in their involvement in the resistance training program and one following completion of the resistance training. The interviews were conducted from an interpretivist framework and were designed to obtain participants' insight into factors that influenced their motivation and weight loss success.
Research Question and Hypotheses: The overarching research question for the study was: What factors influence motivation and weight loss success among eight to twelve year aids participating in a resistance training program? To answer this research question and to guide analysis of the quantitative data four hypotheses were posed:
Over the course of the resistance training program participants with higher intrinsic and extrinsic motivation will experience greater amounts of weight loss compared to participants with lower intrinsic and extrinsic motivation;
Over the course of the resistance training program self-concept will be positively associated with intrinsic motivation and inversely associated with extrinsic motivation;
Individuals who make their overall happiness conditional on their weight loss outcomes will have higher depression symptomatology both before and after the resistance training program compared to mid and low conditional goal setters; and
High conditional goal setters will have lower self-concept and lower motivation before and after the resistance training and lower weight loss outcomes compared to mid and low conditional goal setters.
Participants: Fifty nine participants were recruited to participate in the resistance training program. Eleven left the program within the first few weeks. The remaining 4 7 participants were recruited to participate in the present study. The weight range of participants was 33.79 - 84.64kg and the range of percentage fat in participants' body composition was 25.3 48.7%. Of the 47 participants involved in the quantitative part of this study 10 were recruited to participate in the semi-structured interviews. The weight range of these participants was 45.31-73.29kg and the percentage fat ranged between 37.9-43.4%.
Results: Results of the data analysis revealed that motivation significantly declined between pre-test and post-test and seemingly had little influence upon participants’ weight loss success. There was also no evidence that self-concept affected motivation. Conditional goal setting was found to significantly influence participants1 weight loss success as well as their depression, self-concept and motivation. Thematic analysis of the interview transcripts revealed a number of influences on motivation and participants1 weight loss success including the influence of participants' social context, self-concept, experience of autonomy and control and the influence of external forces including parents and the resistance training program.
Conclusion: The present study provided insight into some of the individual factors that affect children1s motivation and weight loss success in a resistance training program. Implications of this information for future research are discussed.

Full textAbstract:
The obesity epidemic remains a serious issue in the United States leading to significant public health implications and costs. Few weight loss interventions paring mobile technology with face-to-face interventions have been conducted in rural communities. Yet, mobile technology interventions offer good potential for delivery but it is unclear if the combination of these weight loss strategies are beneficial. This study sought to examine how integrating mobile technology with face-to-face weight loss interventions in rural communities affects weight loss. Additionally, to determine if mobile technology paired with face-to-face interventions could increase autonomous and controlled motivation levels among adults in rural Kentucky. The addition of mobile technology with face-to-face intervention provided no significant interaction effect for weight loss compared to the mobile technology group alone. However, a group and time effect was observed for weight loss change. An interaction effect for autonomous motivation indicated that neither group changed independently, but comparing their change over time, the intervention group increased while the control group decreased. A time effect was found as controlled motivation decreased from baseline to final. Future research is required to develop weight loss interventions using technology and face-to-face strategies that may enhance motivation and weight loss outcomes.

Full textAbstract:
A considerable percentage of the UK population are overweight (BMI≥25kg/m2) or obese (BMI≥30kg/m2). However, despite living in the same culture and exposed to a similar “obesogenic” environment, some individuals gain weight while others do not (French et al., 1995). This variability in weight control has been suggested to be associated with individual differences in eating behaviours (French et al., 2012). Certain factors, such as motivation (hedonic hunger and hunger status) as well as cognition (impulsivity and memory) may have an impact on eating behaviours and their relationship with weight control. Thus, the objective of this thesis was to explore individual differences in eating behaviours and investigate their relationship with motivation, cognition and weight control. The first experiment (Chapter 2) investigated the relationship between eating behaviours, motivation (hedonic hunger) and food consumption during an ad-libitum buffet. This study suggests that restrained eating behaviour was associated with higher overall energy intake, greater energy intake from unhealthy foods and greater energy intake from both high and low energy dense foods. However, no interactions between restraint and disinhibition or hedonic hunger was seen. Following this, the second experiment (Chapter 3) examined whether eating behaviours, such as disinhibition, restraint and hunger, change during a weight loss and weight maintenance period and whether they could predict changes in weight during these periods. Indeed, the results suggest that lower baseline restraint could predict greater weight loss during a low-energy liquid diet and interventions which increase restraint and decrease disinhibition may be beneficial for longer term weight maintenance. The third experiment (Chapter 4) was designed to investigate whether motivation and cognition influences eating behaviours. The results suggest that hedonic hunger, restraint and impulsivity may lead to higher levels of disinhibited eating behaviour. This study was also able to replicate the findings of previous literature suggesting that episodic memory is negatively associated with BMI (Cheke et al., 2016). Finally, following on from the previous study results, the fourth experiment (Chapter 5) included a more diverse sample of participants including dieters. The results provide evidence that individuals on a diet have poorer episodic memory ability than those currently not on a diet. This study also extended previous results suggesting that hedonic hunger (but also episodic memory and hunger) are important factors in disinhibited eating. Hedonic hunger was also shown to be important in levels of hunger.

I dagens samhälle är hälften av alla män överviktiga, drygt en tredjedel av alla kvinnor och vart femte barn är överviktiga eller feta (Svenska livsmedelsverket, 2010). Med detta i åtanke väcktes tanken angående hur överviktiga individer motiveras i en process av viktnedgång. Syftet med studien var att undersöka uppfattningar av motivation hos överviktiga individer som genomgår en viktminskningsprocess. Vidare var även syftet att undersöka hur dessa individer påverkas av att genomgå en viktminskningsprocess i grupp. Detta är en fenomenografisk studie där intervjuer har genomförts med tre individer som är i en pågående viktminskningsprocess hos ett viktminskningsföretag. Efter en bearbetning av det empiriska materialet kunde tre beskrivningskategorier utläsas, att komma igång, att nå framsteg samt att blicka framåt. Resultatet visade på många skillnader, men också likheter i individernas uppfattningar av motivation. Slutsatsen blev att respondenterna fann motivation i form av ett stort stöd hos gruppen på viktminskningsföretag, vilket var viktigt för dem i deras viktminskningsprocess, samt att en snabb start i början av processen ökar motivationen för den resterande resan

Syftet med denna studie var att uttyda faktorer som bidrar till en långvarig beteendeförändring. Beteendeförändringar är i regel svåra att vidmakthålla och forskning har visat att ett flertal faktorer krävs för att nå ett långvarigt ihållande. Exempel på faktorer var känsla av sammanhang, kunskap, självkänsla, självtillit, reflektion, medvetenhet, motivation och gruppstöd. En fallstudie har genomförts på en viktminskningsgrupp för att se resultatet ett år efter deltagandet. Fem personer svarade på postenkäterna som skickades ut i uppföljningen. Resultatet visade att nämnda faktorer har påverkat deltagarnas förändringsarbeten men det verkade inte räcka med en faktor utan upplevdes som ett komplext system. Det krävs mer forskning på området för att yrkesverksamma ska kunna hjälpa individer på ett effektivt och framgångsrikt sätt.

NoThis work aims to develop a personalised avatar based virtual environment for motivating weight loss and weight management. Obesity is a worldwide epidemic which has not only enormous resource impact for the healthcare systems but also has substantial health as well as a psychological effect among the individuals who are affected. We propose to tackle this issue via the development of a personalised avatar, the form of which can be adjusted to show the present and the future self of the individual. For the avatar design and development phase, we utilise a parametric based mathematical formulation derived from the solutions of a chosen elliptic partial differential equation. This method not only enables us to generate a parameterised avatar model, but it also allows us to quickly and efficiently create various avatar shapes corresponding to different body weights and even to different body postures.

The purpose of the study was to evaluate the feasibility of utilizing an existing web based weight loss program and the effectiveness of the program in increasing self efficacy and motivation for weight loss among obese women with PCOS. There is consensus among many infertility experts that weight loss should be the first line of therapy for infertility and PCOS among obese women desiring pregnancy. Web based interventions have been effective in other areas of health behavior change. However, there have been no studies to evaluate use of a web-based weight loss program with the targeted population. Bandura's Social Cognitive Theory provides the basis for the contention that self efficacy is a major factor in self regulation. Another factor is motivation, which enhances self efficacy, thus creating behavior change. A sample of nine women participated in the one group pretest/posttest study measuring self efficacy, motivation and web site visits. BMI was calculated based on self-reported height and weight at baseline and after four weeks as a secondary outcome. There were significant increases in both self-efficacy and motivation for weight loss. Feasibility measures were not met at 90%. Eight of nine participants decreased their BMI. These results support utilization of currently available, free, online weight loss programs for this population.

Full textAbstract:
Background Nearly a quarter of UK adults are obese representing a significant public health problem. Motivational interviewing (MI) may be effective in helping people to lose weight. Planning could be a mechanism of action which is related to outcome. The aim is to define the types of planning talk used by clients during an MI session and examine their relation to weight loss maintenance (WLM) outcomes. Also to examine the skills the therapist used prior to a client talking about planning. Methods To define planning talk a literature review was conducted and an expert group listened to recorded MI sessions. Thematic content analysis was used to identify the types of planning talk. Thematic analysis was used to identify the therapist skills prior to planning within 50 MI sessions. Associations between types of planning talk and WLM outcomes were analysed using logistic and linear regression. Results The development of the coding system found several types of plans/goals. The reliability was 86% and 75% agreement with the gold standard, for examples of plans/goals and the transcript respectively. Frequent planners lost on average 2.8 kgs (95% CI) and 1.2kg/m² (95% CI) more than those who were low planners (not statistically significant). Medium goal setters statistically significantly increased on average their weight (8.8kg) and BMI (3.5 kg/m²) compared to low goal setters. Therapist’s skills prior to planning were asking the client planning questions and exploring with the client their planning ideas in order to increase specificity. Conclusion The coding system can be used to code WLM data with acceptable reliability. A possible association between planning and a decrease in weight and BMI was demonstrated. Understanding how MI works could lead to improvements in the practice of MI by therapist, efficacy, focus research efforts and facilitate a better understanding of what helps people to change behaviours.

Obesity is a pandemic that has a substantial impact among African American women. Biological, social, and cultural acceptance of obesity, collectively referred to as biosociocultural factors, represents an obstacle to efforts to address this health risk among this group. The purpose of this study was to develop a better understanding of the relationship between biosociocultural factors and motivation to lose weight. Self-determination theory, objectification theory, and social learning theory formed the study's theoretical framework. The key research question concerned the extent to which the investigated constructs (BMI, internalized body image, and social networks) helped to explain motivation for weight loss among nonpregnant obese African American heterosexual or bisexual women who preferred to date and mate with African American men. The study used a quantitative and correlational cross-sectional survey design. Data were collected from a sample of 183 African American women with obesity. Survey components included a demographic questionnaire, Pulvers's Culturally Relevant Body Image Scale and Questionnaire, the Social Support for Eating Habits Survey, and the Dieting Readiness Test. Multiple regression analyses were used to examine the predictive strength of these factors (BMI, 3 components of internalized body image, and 4 components of social network) for motivation to lose weight. A statistically significant positive relationship was found between motivation to lose weight and 3 predictors (2 components of body image and 1 component of social network). Further examination indicated that body image was the most reliable construct predicting motivation to lose weight. Insights gained from this study may inform the development of culturally sensitive approaches to obesity prevention and intervention for this population.

Childhood obesity is associated with serious physiological and psychological consequences including type 2 diabetes, higher rates of depression and low self-esteem. With the population of overweight and obese youth increasing, appropriate interventions are needed that speak to the issue of motivation to maintain adherence to healthy behavior changes. The current investigation was a randomized controlled trial examining the efficacy of Motivational Interviewing (MI) as an intervention for promoting self-efficacy and weight-loss in a sample of overweight and obese youth. Participants (N = 42) ages 10-18, were randomly assigned to a control (social skills training) or treatment (MI) group. Both groups received individual therapy (~30 minutes/month) in addition to usual care of diet/exercise counseling. Pre and post (at 6 months follow-up) variables included measures of self-efficacy and anthropometrics. Results indicated that while significant between-group differences were not found, individuals in the MI group attended more sessions. Overall, participants in both groups showed significant increases in self-efficacy and a trend of decreased BMI z-scores. Though health benefits from participation in individual therapy may have been accrued, specific benefits attributable to MI were limited. Findings from the current study suggest that more than one type of counseling intervention (i.e., MI and social skills training) may be beneficial when providing integrative treatment for obese youth.Canadian Institutes of Health and Research (CIHR)

Das Krankheitsbild der Adipositas hat sich weltweit zu einem relevanten Gesundheitsproblem entwickelt. Die bariatrische Chirurgie wird zunehmend als wirkungsvolle Behandlung bei schwer ausgeprägter Adipositas eingesetzt. Jedoch ist über die Rolle psychologischer Variablen im bariatrischen Behandlungsverlauf noch wenig bekannt. Die vorliegende Dissertation untersucht Einfluss und Veränderung patientenberichteter Gesundheitsmerkmale in der chirurgischen Adipositastherapie. Dazu werden in einer naturalistischen Beobachtungsstudie Patienten mit schwerer Adipositas vor und im Durchschnitt zwei Jahre nach einer bariatrischen Operation (OP) befragt. Ziele der Arbeit sind 1) die Charakterisierung adipöser Patienten vor OP hinsichtlich bio-psycho-sozialer Variablen; 2) die Identifikation möglicher Einflussvariablen auf den gewichtsbezogenen Behandlungserfolg nach OP; 3) die Untersuchung von Auswirkungen der OP auf das Essverhalten; und 4) die Analyse von Veränderungen in der essstörungsbezogenen Psychopathologie und in der gesundheitsbezogenen Lebensqualität nach OP. Die Ergebnisse der bariatrischen Patienten werden im Vergleich zu denen konservativ behandelter Patienten betrachtet. Die Ergebnisse zeigen, dass Patienten mit bariatrischem Behandlungswunsch eine somatisch und psychisch belastete Patientengruppe darstellen. Die bariatrische OP führt im zweiten postoperativen Jahr zu einer nachhaltigen und klinisch bedeutsamen Gewichtsreduktion. Der präoperative Body-Maß-Index, das Bildungsniveau und aktives Problembewältigungsverhalten sind mit dem Gewichtsverlust nach OP assoziiert. Im Vergleich zur konservativen Behandlung berichten die Patienten, die sich der OP unterziehen, über stärker ausgeprägte Verbesserungen in ihrem Essverhalten und eine Steigerung ihrer Lebensqualität. Auf Basis der Befunde wird ein routinemäßiges Monitoring der somatischen und psychischen Situation der Patienten nach bariatrischer OP empfohlen, um die gezeigten Behandlungserfolge optimal zu sichern.Obesity has become a relevant global health problem. Bariatric surgery is an effective treatment for severe obesity. However, while the number of operations performed continues to increase, the role of psychological variables throughout the bariatric surgery pathway remains uncertain. The present dissertation investigates the patient-reported health status as it impacts and results from bariatric surgery. In a naturalistic observational study, patients with severe obesity are assessed before and, on average, two years after the surgical treatment. Main aims are 1) to characterize obese patients prior to bariatric surgery in terms of biological, psychological and socio-demographic variables; 2) to identify possible predictors for the postoperative weight-related treatment success after bariatric surgery; 3) to examine changes in eating behaviors; and 4) to analyze changes in eating-related psychopathology and in health-related quality of life (HRQoL). The outcomes of surgical patients are compared with those of conservatively treated patients for the same follow-up period. The findings show that bariatric surgery candidates represent a vulnerable patient group with high physical and psychological burden. In the second postoperative year after bariatric surgery, a sustainable and clinically meaningful weight reduction is achieved. The preoperative body mass index, education level and active coping behavior are associated with weight loss after surgery. Compared with conservative treatment, patients who undergo bariatric surgery report not only greater improvements in their eating behavior and eating-related psychopathology but also an increase in their HRQoL. Based on the results, the provision of a routine monitoring of the somatic and psychological situation of patients following bariatric surgery is recommended to secure longer-term treatment success.

Full textAbstract:
Bakgrund: Typ 2 diabetes är ett globalt hälsoproblem som kan ge allvarliga komplikationer. Livsstilsförändringar inom fysisk aktivitet och kost kan minska risken för komplikationer och leda till viktnedgång hos patienter med övervikt eller fetma. Motiverande samtal (MI) har som syfte att öka patientens motivation. MI används som ett hjälpmedel inom hälso-och sjukvården för att motivera patienter till livsstilsförändring. Inom rådgivning har sjuksköterskan en viktig hälsofrämjande arbetsroll att motivera patienter till livsstilsförändringar avseende ökad fysisk aktivitet och kostvanor. Syfte: Att sammanställa aktuell forskning om betydelsen av MI avseende livsstilsförändringar hos patienter med typ 2 diabetes. Metod: Designen är en litteraturöversikt som grundar sig på 15 vetenskapliga artiklar. Datainsamlingen har genomförts via PubMed och Cinahl. Resultat: Tre huvudkategorier med tillhörande subkategorier framtogs. Huvudkategorierna var: Betydelsen av MI avseende kost, betydelsen av MI avseende viktnedgång och betydelsen av MI avseende fysisk aktivitet. Konklusion: Samtalsmetoden MI gav olika resultat avseende kost och fysisk aktivitet samt viktnedgång. En gemensam faktor som identifierades var att MI gav förståelse för deltagarnas aktuella livsstil tillsammans med ökad motivation.Background: Type 2 diabetes is a global health problem that can cause complications.

This research is based on the qualitative research method that interviewed participants who took part in the weight loss program under a coach’s guidance, further discussing about why they chose to join the program. This research also applies Maslow's Hierarchy of Needs to analyze the participants’ motive of taking part in the weight loss program. Six participants are invited in this research: three are weight loss coaches while the others are members in the weight loss program. This semi-structured interview has been reviewed and summarized by the researcher into these following points: 1:Reasons of the members participating in the weight loss program under the coach’s guidance: A. Seeking for more professional knowledge about how to lose weight. B. Understanding the correct way of dieting C. Acquiring professional guidance D. Feeling that professional coaches are persuasive by their appearance. E. Acquiring a companion to facilitate the dieting progress. 2:Motivation of the members joining the weight loss program: A. Controlled Diet Being able to resist hunger and lose weight at the same time. Learning how to cook with low GI ingredients. Making better choices while eating out in order to lose weight. B. Efficient Exercises Making losing weight in itself their only purpose, instead of losing weight in order to lessen their inflicted illness. C. Corrective Basic Behavior Finding partners that have the same goal and motivation to lose weight and get healthier together. D. Corrective Advanced Behavior Having the ability to increase one’s confidence due to the decrease of weight. E. Coach’s Guidance Feeling accomplished by having the ability to share the knowledge of losing weight with others. Researcher’s suggestion: 1. The coaches need to ： Establish a positive habit of gaining more advanced knowledge. 2. Always stay fit in order to inspire the members. 3. Develop low glycemic index diets that are colorful, aromatic, tasty, and capable of changing their daily eating habits. 4. For further researches: They should ：Apply methods are carried out qualitatively and quantitatively. Develop more low GI recipes for people who are in a diet. Invent behavioral patterns of losing weight which are sharable.

Full textAbstract:
This dissertation thought to provide a comprehensive understanding of weight loss- and maintenance-related processes among adults. Specifically, it comprises a set of five studies that were designed to i) determine the prevalence of weight control attempts and identify correlates, personal strategies, and motives underlying these attempts; ii) examine behavioral and psychological characteristics as predictors of successful weight loss and maintenance; and iii) examine psychological predictors of physical activity, a critical behavior for successful weight control.
Studies I and II reflect the state of the art regarding the prevalence of weight control attempts among adults on a global and national level, respectively, showing that weight is a matter of concern to a significant portion of the adult population. Study III aimed for a more in-depth understanding of who succeeds in weight loss and maintenance, showing that there is a multiplicity of potentially successful behaviors and strategies. Subsequently, study IV showed that psychological factors underlying the weight control behaviors, such as positive body image and autonomous motivation, have a critical role in the process. Finally, study V confirmed that more autonomous forms of motivation are key for maintaining physical activity behavior over time in those trying to achieve weight loss and maintenance.
The findings in this thesis highlight the need for, and importance of developing long-term individualized approaches for successful weight loss and maintenance, under the umbrella of motivation and related psychological factors. Future weight management initiatives would benefit from targeting combinations of evidence-based weight control strategies and the improvement of body image and motivation quality as potential precursors of those strategies, in order to promote long-term weight loss maintenance. Furthermore, it has become clear that weight control attempts are prevalent in Portugal and worldwide and consequently changes and trends should be monitored regularly in order to inform and advance future practice.Esta dissertação teve como objetivo promover um entendimento alargado no que respeita aos processos relacionados com a perda e manutenção do peso em adultos. Inclui um conjunto de cinco estudos com o intuito de i) determinar a prevalência das tentativas de controlo do peso e identificar correlatos, as estratégias utilizadas e os motivos associados; ii) explorar características comportamentais e psicológicas como preditores da perda e manutenção do peso com sucesso; e iii) explorar preditores psicológicos da atividade física, um comportamento crítico para o sucesso no controlo do peso. Os estudos I e II refletem o estado da arte no que respeita às tentativas de controlo do peso em adultos, respectivamente a nível global e nacional, revelando que o peso é uma preocupação para uma porção significativa da população adulta. O estudo III procurou compreender quem efetivamente conseguiu perder e manter o peso, revelando que há uma panóplia de potenciais estratégias e comportamentos de sucesso. Subsequentemente, o estudo IV mostrou que factores psicológicos subjacentes aos comportamentos de controlo do peso, como por exemplo uma imagem corporal positiva e motivação autónoma, têm um papel crítico no processo. Por fim, o estudo V confirmou que motivações mais autónomas são cruciais para a manutenção da atividade física a longo prazo em pessoas a tentar perder e manter o peso. Em conjunto, os resultados desta tese sublinham a necessidade e a importância de desenvolver abordagens de longo-prazo individualizadas para o sucesso na perda e manutenção do peso, sob a égide da motivação e factores psicológicos relacionados. Iniciativas futuras de gestão do peso irão beneficiar de uma abordagem direcionada a estratégias de controlo do peso baseadas na evidência e à melhoria da imagem corporal e da qualidade da motivação como potenciais percursores destas estratégias, de forma a promover a manutenção do peso perdido. Adicionalmente, tornou-se claro que as tentativas de controlo do peso são prevalentes em Portugal e em todo o mundo e, consequentemente, as alterações e tendências de controlo do peso devem ser monitorizadas regularmente de forma a informar e desenvolver a prática futura.

Professional Doctorate - Doctor of Clinical and Health PsychologyPurpose: Being obese or overweight has negative health implications and is a growing problem in Australia with 62.8% of the Australian population now overweight or obese. The objective of this study was to examine in detail examples of individuals who had achieved healthy lifestyle change, in the form of a 10% weight reduction, and what prompted their efforts to change. By understanding the motivators that trigger successful weight loss in those who have been able to maintain weight loss, more effective health promotion campaigns can be developed to address the obesity epidemic in the broader community. Methodology: An in-depth qualitative methodology was utilized in order to obtain rich data regarding the motivations to embark on a weight loss journey. Participants: who had lost 10% of their body weight following the implementation of a changes diet and exercise regime were invited to participate via posters placed in the campus of the University of Newcastle, local gyms and community health centres. Six participants were interviewed (3 men and 3 women), ranging in age from 29 to 55 years. Face-to-face semi-structured interviews were conducted by the female author, [KR] at the University of Newcastle. Each interview was audio recorded and transcribed verbatim. Interviews took place over a six month period in 2013 and ranged in duration from one hour to just under two hours. Interview transcripts were analysed using Interpretative Phenomenological Analysis (IPA) (Smith, 1996). Results: Five main themes were identified from the research in relation to motivation for lifestyle change for weight loss. These themes were identified as 1) Motivational Kickstart; 2)Staying on Track; 3) Challenges to Ongoing Motivation; 4) Future Concerns; and 5) The Self and Others. General Conclusions and Implications: The current study identified that a trigger to action, whether it be internal or external to the participant, as a key motivational factors in prompting behavioural change relating to diet and exercise. Additionally, challenges and facilitators of ongoing motivation to continue new dietary and activity related behaviours are identified by participants. Concerns for possible future selves were identified as motivating sustained behaviour change enabling weight loss. Changing social interactions were identified as both supportive and potentially posing a threat to sustained motivation for weight loss.

The purpose of this research was to develop, validate, and test an instrument to evaluate motivations to eat in low-income women during the early postpartum period. The instrument was also used in a sample of young college women to further validate the measure and explore determinants of eating in this population. In study 1, the Eating Stimulus Index was validated in 179 low-income women in early postpartum. Validity and reliability were determined via principal components analysis, internal consistency reliability, and test-retest reliability using a subgroup of 31 low-income new mothers. The factor analysis produced an eight factor structure with reliability coefficients ranging from 0.54-0.89. Convenience eating (r=-0.25, P<0.01), emotional eating (r=-0.17, P<0.05), and dietary restraint (r=-0.21, P<0.01) were significantly related to weight status. In study 2, the relationship between eating motivations and diet quality, determined via the Dietary Guidelines Adherence Index, was established in 115 low-income women in early postpartum. High diet quality was related to fruit and vegetable availability (r=0.25, P<0.01), convenience eating resistance (r=-0.36, P<0.001), and vegetable taste preference (r=0.23, P<0.05). Motivations to eat differed between overweight and obese women with the primary motivation being convenience eating and taste, respectively. In study 3, determinants of weight loss were examined in 58 low-income women in early postpartum participating in an 8-week weight loss intervention. Participants were evaluated at pre- and post-study for all measures. Factors related to weight loss included increases in dietary restraint, weight management skills, and weight loss self-efficacy and decreases in fruit juice servings, total energy, and discretionary energy intakes. After hierarchical regression analysis, improvement in weight loss self-efficacy was the most significant determinant (β=0.263, P<0.05) followed by decreases in discretionary energy intake (β=-0.241, P<0.05). In study 4, determinants of diet quality were assessed in a sample of 88 young college women using the Eating Stimulus Index. Low diet quality was associated with poor fruit and vegetable availability, convenience eating resistance, vegetable taste preference, and weight management self-efficacy, while high diet quality was related to increased frequency of meals prepared at home and decreased frequency of meals consumed at fast food restaurants.text

yesBackground The interaction between motivation to eat, eating behaviour traits and gut peptides following gastric bypass (GBP) surgery are not fully understood. Setting Danderyd Hospital, Karolinska Institutet, Stockholm, Sweden. Method Appetite and hormone responses to a fixed liquid pre-load were assessed in 12 obese (BMI 45 ± 1.9 kg/m2) participants immediately before, 3 days, 2 months, and 1 year following gastric by-pass (GBP) surgery. Subjective appetite and plasma levels of ghrelin, leptin, insulin and GLP-1 were measured for a 3-hour postprandial period. Eating behaviour traits were also measured using the TFEQR18. Results There was a decrease in TFEQ Emotional Eating (EE) and Uncontrolled Eating (UE) from pre to 1-year post-surgery, but no significant change in Restraint. In addition, there was a reduction in subjective appetite ratings, and alterations in appetite peptides favouring an anorectic response. Pre-surgery EE was significantly related to fasting and AUC ghrelin; UE was associated with AUC desire to eat while there was a significant association between fasting desire to eat and ghrelin (fasting and AUC). 1 year post-surgery, UE was positively related to fasting insulin and Restraint was negatively associated with GLP-1. UE and subjective hunger were positively correlated, while the relationship between desire to eat and ghrelin remained. Conclusion The relationships amongst subjective appetite ratings, eating behaviour traits and appetite peptides in obese patients both before and at one-year post GBP surgery contribute to the reduction in a propensity to over-eat and weight loss.

Orientação: António João Labisa da Silva PalmeiraObjetivo: Esta dissertação teve como objetivo principal a identificação de níveis de atividade física ao longo de 12 meses, com Machine Learning, e a sua associação com variáveis motivacionais, em adultos em processo de manutenção de perda de peso no projeto NoHoW. Método: O trabalho foi dividido em duas partes, em primeiro lugar foi efetuada uma Revisão Sistemática da Literatura rápida, na qual se procurou analisar a utilização de inteligência artificial no contexto da adesão à atividade física e gestão do peso e seguidamente foi realizado um estudo de Cohort prospetivo, com uma amostra de 1627 indivíduos. Utilizou-se a informação recolhida de FiBit (24/7) durante 12 meses e respostas a questionários motivacionais aplicados no Baseline, 6 e 12 meses. Resultados: Na Revisão Sistemática da Literatura rápida verificou-se que a literatura aponta para que intervenções personalizadas são essenciais para o sucesso individual da gestão do peso. Relativamente aos estudos focados em modelos preditivos, os resultados mostraram que a prática de atividade física se ajusta aos padrões de vida atuais e que os preditores para a prática de atividade física parecem estar associados a fatores psicológicos e comportamentais dos indivíduos. No estudo de Cohort prospetivo identificaram-se 2 grupos com diferentes níveis de atividade física, os ativos (Ativ) e os insuficientemente ativos (I-Ativ), com perfis motivacionais distintos. No grupo Ativ, as variáveis RAI, Motivação Autónoma, Regulações Intrínseca, Integrada e Identificada têm valores mais elevados, nos períodos em análise, em comparação com os valores dos indivíduos I-Ativ. Os indicadores motivacionais variam ao longo do tempo, com tendência crescente no início do projeto, verificando-se uma estagnação a partir dos 6 meses e redução em ambos os grupos no final dos 12 meses. Conclusões: No que respeita a Revisão Sistemática da Literatura rápida, concluiu-se que a inteligência artificial e os métodos de Machine Learning aplicados à gestão do peso e à promoção da prática de atividade física podem ser uma enorme vantagem e poderão apoiar na redução das taxas de obesidade. No estudo de Cohort prospetivo foi possível a segregação de indivíduos por padrões de atividade física, com métodos de Machine Learning. São níveis elevados de Motivação Autónoma, Regulação Intrínseca, Integrada e Identificada ao longo dos 12 meses que parecem permitir que os indivíduos pratiquem ativamente atividade física. A Autonomia, no contexto da gestão do peso, aos 12 meses deverá ser avaliada, pela sua diminuição face ao nível no Baseline.
Objective: This dissertation main objective was to identify physical activity levels over 12 months, with Machine Learning, and its association with motivational variables, in adults undergoing weight loss maintenance in the NoHoW project. Method: The work was divided in two parts, first a Fast-Systematic Review of the Literature was carried out to analyze the use of artificial intelligence in the context of adherence to physical activity and weight management and second a Cohort's prospective study was conducted, we used a sample of 1627 individuals, FiBit information (24/7) for 12 months and motivational questionnaires output applied at Baseline, 6 and 12 months. Results: In the Fast-Systematic Review of the Literature, studies indicated that personalized interventions are essential for individual weight management success. Concerning studies focused on predictive models, the results showed that physical activity practice adapts to current living standards and that predictors for physical activity practice seem to be associated with psychological and behavioral factors. In the prospective Cohort study, 2 groups with different levels of physical activity were identified: active (Activ) and somewhat active (I-Ativ), with different motivational profiles. In the Ativ group, the variables RAI, Autonomous Motivation, Intrinsic, Integrated and Identified Regulations have higher values when compared to the values of I-Ativ group. Motivational indicators vary over time, with an upward trend at the beginning of the project, stagnation starting at 6 months and decreasing in both groups at the end of 12 months. Conclusions: The Fast-Systematic Review of the rapid literature made us conclude that artificial intelligence and Machine Learning methods applied to weight management and the enhancement of physical activity practice are a huge advantage and may help to reduce obesity rates. In the prospective Cohort study, with Machine Learning methods, it is possible to segregate individuals by patterns of physical activity. High levels of Autonomous Motivation, Intrinsic Regulation, Integrated and Identified over the 12 months seem to allow individuals to actively engage in physical activity. Autonomy in the context of weight management at 12 months should be assessed.

This diploma thesis deals with obese patients' motivation to undergo or refuse a bariatric surgery in obesity treatment. The aim of the thesis was to create an overview of patient's motivation to undergo or refuse a bariatric surgery, to show an obese patient's situation (a candidate for a bariatric surgery) from a closer perspective and offer recommendations for the work with obese patients. The qualitative research method in a form of a semistructured interview with the obese patients, who are being treated in obesity ambulances, and with the psychologists, who work with obese patients, was used to analyse the theme of the research. The eight interviews were conducted and analysed with open coding. Obese patients are motivated to undergo a bariatric surgery by improvement of their health, increased attractiveness and by expectation of their obesity's final solution. Obese patients don't want to undergo a bariatric surgery because they're convinced, that they could manage to lose weight and keep it without undergoing a bariatric surgery. Also because they are worried about the bariatric surgery, its complications, its restrictions, required anesthesia and about the failure after undergoing bariatric surgery. Obese patients' motivation to undergo or refuse a bariatric surgery is also influenced by...
