Abstract (sommario):

The purpose of this study was to examine the effect of a single bout of exercise on neurocognitive function in preadolescent children and young adults by determining the modulatory role of age and the neuroelectrical mechanism(s) underlying the association between acute exercise and executive function. Twenty preadolescents and 20 young adults completed the Stroop test, and neuroelectrical activity was recorded during two treatment sessions performed in a counterbalanced order. Exercise treatments involved moderate intensity aerobic exercise for 20 min as the main exercise and two 5 min periods of warm-up and cool-down. The control treatment participants read for a similar duration of time. Acute exercise improved participant reaction times on the Stroop test, regardless of Stroop congruency, and greater beneficial effects were observed in young adults compared to those in preadolescents. The P3 amplitudes increased after acute exercise in preadolescents and young adults, but acute exercise induced lower conflict sustained potential (conflict SP) amplitudes in preadolescent children. Based on these findings, age influences the beneficial effect of acute exercise on cognitive performance in general. Furthermore, the event-related brain potential differences attributed to acute exercise provide a potential clue to the mechanisms that differentiate the effects of acute exercise on individuals from preadolescence to young adulthood.

Abstract (sommario):

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were conceptualized and constructed based on existing theories. Study I checked the suitability of these items among preadolescent and adolescent age groups. After revisions, Study II was done to evaluate the item properties using item response theory. Subsequently done Confirmatory Factor Analysis provided evidence for the construct validity of the new measure. Finally, Study III was done to develop the age wise and gender wise norms for preadolescent and adolescent age groups. The newly developed measure was found to have sufficient reliability and validity and hence can be widely applied for measuring mental rotation of preadolescents and adolescents.

Abstract (sommario):

Resourcefulness is a set of cognitive-behavioral self-control skills for coping with stress to maintain quality of life. However, research examining precursors in the development of resourcefulness in preadolescents is scant. A cross-sectional approach was used to investigate hypothesized predicting effects of intrinsic contextual factors (children’s age, gender, and school performance), extrinsic contextual factors (parents’ age, gender, education, income, and resourcefulness), and process regulators (academic stress and dispositional optimism) in a convenience sample of 361 preadolescent–parent dyads. Results show that preadolescents’ process regulators, academic stress, and dispositional optimism were significant predictors of resourcefulness. The findings suggest that preadolescents’ resourcefulness was greatly influenced by process regulators, which are cognitive perceptions intervening the use of resourcefulness. Further research with various study designs is needed to examine additional factors that may influence resourcefulness in large and more diverse child–parent samples.

Abstract (sommario):

The crisis of public spaces implies a closure to the private sphere and, as a consequence, the inanity of the education processes. Space privatization involves the supremacy of the “οίκος” (house) on the “αγορα” (public space), so that the house assumes the role of an enclosed community. The effect of this closure is a weakening of the spatial identification and socialization of preadolescents and the exclusion of differences and relationships with their peers. This break prevents and reduces the autonomous exploration of the space as a place of free expression, the communicative acting, the conflict. This article analyzes the efficacy of the educative role of the quarter and its incidence on the preadolescent development from a sheltered to an open space both through a deep relationship with the environment and an aptitude to explore the external world. The validity of these hypotheses has been proved through a study carried out in three cities.

Abstract (sommario):

Families and schools are important environments that contribute to the resilience and positive development of preadolescent children. Sense of mastery, including its two central factors of optimism and self-efficacy, forms an important component of resilience during preadolescence (Prince-Embury, 2007). This study examined the interrelationships between family functioning, school connectedness, and sense of mastery in 75 children (46 girls and 29 boys) from a government school in Melbourne, Australia. Data was gathered from students aged 10 to 12 years through three self-report questionnaires. Negative perceptions of family functioning were significantly associated with the resilience factors of low sense of mastery, optimism, and self-efficacy. Higher school connectedness was significantly associated with greater sense of mastery, optimism, and self-efficacy. Additional evaluation revealed school connectedness to partially mediate the relationship between family functioning and sense of mastery. School connectedness appears to be a protective factor against the negative influence of poor family functioning. Findings highlight the important role of school connectedness in preadolescent resilience, as measured in terms of mastery, and suggest that interventions directed to enhance school connectedness are of value, particularly for children from poorly functioning families.

Abstract (sommario):

Parental practices such as inconsistent discipline, psychological control, and imposition have been linked to the development of internalizing and externalizing problem behaviors in preadolescents. This study aimed to identify the association these practices had on Mexican preadolescent problem behaviors through Structural Equation Modeling. The sample consisted of 306 elementary students from three public schools in Mexico City (age M = 10, SD = 0.92). Students completed subscales from the Parental Practice Scale, the Alabama Parenting Questionnaire, and the Strengths and Difficulties Questionnaire. Paternal imposition and maternal psychological control were significant predictors for internalizing problems, while inconsistent discipline was a significant predictor of externalizing problems. The results highlight that although parental practicevalues might differ across cultures, their association to problem behaviors are similar.

Abstract (sommario):

Growing up in a high family risk (HFR) environment is accompanied by difficulties in executive functions (EFs) and interpersonal skills (IS) that may persist into adulthood. Because preadolescence is a critical period, this study will assess a multicomponent mediational intervention program, to determine the possibility of improving these skills. There were 61 preadolescent participants, between the ages of 8 and 12; 34 were associated with HFR and 27 were associated with low family risk (LFR). All the participants were tested with EF and IS measures. Results showed that, prior to treatment, the HFR preadolescents had poorer performance on EF and IS than did the LFR preadolescents. In the posttreatment measures, to assess the utility of the multicomponent program, the HFR preadolescents group was able to match the scores of those in the LFR group. In addition, intervention effects in the HFR group were maintained in the follow-up assessment.

Abstract (sommario):

Whereas the adolescent brain is a major target for gonadal hormones, our understanding of hormonal influences on adolescent neural and behavioral development remains limited. These experiments investigated how variations in the timing of testosterone (T) exposure, relative to adolescence, alters the strength of steroid-sensitive neural circuits underlying social behavior in male Syrian hamsters. Experiment 1 simulated early, on-time, and late pubertal development by gonadectomizing males on postnatal d 10 and treating with SILASTIC brand T implants for 19 d before, during, or after adolescence. T treatment before or during, but not after, adolescence facilitated mating behavior in adulthood. In addition, preadolescent T treatments most effectively increased mating behavior overall, indicating that the timing of exposure to pubertal hormones contributes to individual differences in adult behavior. Experiment 2 examined the effects of preadolescent T treatment on behavior and brain regional volumes within the mating neural circuit of juvenile males (i.e. still preadolescent). Although preadolescent T treatment did not induce reproductive behavior in juvenile males, it did increase volumes of the bed nucleus of the stria terminalis, sexually dimorphic nucleus, posterodorsal medial amygdala, and posteroventral medial amygdala to adult-typical size. In contrast, juvenile anterodorsal medial amygdala and ventromedial hypothalamus volumes were not changed by preadolescent T treatment yet differed significantly in volume from adult controls, suggesting that further maturation of these brain regions during adolescence is required for the expression of male reproductive behavior. Thus, adolescent maturation of social behavior may involve both steroid-independent and -dependent processes, and adolescence marks the end of a postnatal period of sensitivity to steroid-dependent organization of the brain.

Abstract (sommario):

AbstractIn contrast to victimization, prior research on the antecedents and outcomes of bullying perpetration has provided little conclusive knowledge. Some adolescent bullies may be well adjusted and popular among peers, while other bullies are rejected and lack self-control. There is also great variation in the outcomes, with a number of studies (but not all) showing increased risk for externalizing and internalizing problems. We used a developmental framework and data from 2,230 participants of the Dutch Tracking Adolescents’ Individual Lives Survey (TRAILS) to examine bullying perpetration across adolescence, to test the links with various antecedents in preadolescence, and to elucidate the outcomes in early adulthood. Latent growth models indicated significant variance in initial bullying perpetration levels and an overall decrease between pre- and late adolescence. Individual, family, and peer factors were associated with initial levels and partially associated with bullying development over time. Bullying perpetration was linked to later maladjustment and substance use, although only in girls. Finally, bullying perpetration appears to function as an intermediate variable between preadolescent individual, family, and peer risk and substance use more than 10 years later. These results have important implications for understanding the gender-specific nature of bullying perpetration and its outcomes and for demonstrating that bullying carries early risk into adulthood.

AbstractThe aim of this article is to describe the development of a short version of the Coping Scale for Children (CSC) for situations in which use of the full form is precluded by time constraints or the demands of other measures. Utilizing data from prior studies (e.g., jones & Frydenberg, 2004; Larkins & Frydenberg, 2004) a short form was constructed and the psychometric properties investigated with schoolchildren (N = 379) drawn from primary schools in Metropolitan Melbourne. Using Principal Components Analysis with Varimax rotation, two dimensions of coping (Adaptive Coping and Maladaptive Coping) were found to be both robust ond suitable for investigating styles of coping with stress in preadolescent children aged 10- to 12- years. In addition, this poper analysed associations between the resulting factors and self-esteem, as assessed by the Weinberger Adjustment Inventory (Weinberger, Feldman, & Ford, 1989). The CSCSF appears to have promising applications as a short measure of critical dimensions of coping in preadolescent children, with good psychometric properties.

Abstract (sommario):

Abstract Objectives Parents play an important role in keeping their children safe. However, this becomes more difficult during preadolescence as children seek greater autonomy away from the direct supervision of adults. The current study focused on preadolescent youth (10–13 years) and examined parent–child disagreements about safety, with a focus on determining if child temperament attributes moderate the relation between how parents learn of these and resolve these disagreements. Methods A short-term longitudinal design was used. Parents and children retrospectively recalled safety disagreements together and then independently completed questionnaires about these. Parents then tracked disagreements over 1 month. Results The behavioral attributes of inhibitory control and risk-taking propensity both moderated the relationships between parental source of knowledge of safety disagreements and subsequent methods of resolution. Conclusion Safety-promotion messaging for parents of preadolescents may need to be tailored based on child attributes to maximize effectiveness.

Abstract (sommario):

This article examines the relationship between precocious puberty and the self-esteem of preadolescent girls in public primary schools in Kiambu County, Kenya. This article introduces the two variables precocious puberty and self-esteem, reviews the literature on the relationship between the physical, biological, cognitive, and cultural changes of precocious puberty as they relate to the self-esteem of adolescent girls, discusses the findings of the study, and makes conclusions and recommendations. The sample population was 410 preadolescent girls and 8 class teachers, who were purposively sampled from 12 randomly, selected public primary schools in Kiambu County. Primary data was collected using three instruments; a questionnaire structured interviews and focus group discussions. The instruments were pilot tested on 36, 8-12 years old girls from 3 public primary schools in the study location who were omitted from the actual study. The qualitative data was analysed using the content analysis method, while the quantitative data was analysed using the Statistical Package for Social Sciences (SPSS) version 26. Analysed data was presented using tables and figures. Statistical data indicated that there was a significant relationship (β=0.354, p=0.000) between precocious puberty and the self-esteem of pre-adolescent girls. This was confirmed by the responses from both interviews and focus group discussions. Given these findings, the researcher study concluded that earlier pubertal maturation as indicated by breast development before age 8 and the onset of menstruation before age 12 can lead to low self-esteem in preadolescent girls. The article recommends that awareness of the incidence of precocious puberty and its relationship with the self-esteem of preadolescent girls be created among parents, teachers, peers, policymakers, and other stakeholders so that the negative effects from the incidence can be mitigated.

Abstract (sommario):

Objective: Childhood undernutrition may result in poor physical development, and negatively impact on the workforce and society. We examined from the literature how micronutrient deficiencies may affect bone growth in preadolescent children in developing countries. Results: Overall data from many studies carried out during the past 30 years show that dietary supplementation of children in developing countries may improve growth and development. Although the first few months and years of life have been considered key to these improvements, supplementation at any age may be able to influence bone health and physical development. There is considerable data in support of calcium supplementation, either in tablet form or from increased intake of dairy products, but it now seems likely that calcium alone may not be sufficient to enhance growth, unless other vital micronutrients are also provided. The recent societal changes in South Africa have resulted in an influx of cheap, nutrient-poor foods, leading to widespread childhood undernourishment in mainly black children in resource-constrained communities. Data on dietary supplementation and long-term outcomes in these children are still lacking. Conclusion: An understanding of the complex interactions between macro- and micronutrients in enhancing physical growth and development, and a consensus on the optimal timing and delivery system of supplementation is required to improve child health in developing countries, including Africa. The efficacy and efficiency of food based programmes versus supplementation should be critically assessed.

Abstract (sommario):

This article discusses the relationship between precocious puberty and the peer relationships of preadolescent girls in public primary schools in Kiambu County, Kenya. This article is based on a case study of twelve selected public primary schools (representing the 12 constituencies) of Kiambu County, Kenya. The sample population was a total of four hundred and ten pre-teenage girls drawn from eight to twelve-year-old girls, and eight class teachers, who were purposively sampled from twelve randomly selected public primary schools in the study location. This was a mixed study that utilized both quantitative and qualitative data collection methods. The self-rating scale for pubertal maturation and the peer connectedness scale was used to assess for signs of precocious puberty and the quality of peer relationships respectively. In addition, structured interviews and focus group discussions were used to gather additional primary data. The instruments were pilot-tested on a sample of thirty-six respondents who were purposively sampled from three public primary schools in the sample location, and who were omitted from the actual study sample. The quantitative data was analysed using the Statistical Package for Social Sciences (SPSS) version 26, while the qualitative data was analysed using the content analysis approach. Analysed data was presented using both figures and tables. This study found a significant relationship (β=0.258, p=0.011) between precocious puberty and peer relationships among preadolescent girls. This was confirmed by the interview responses and the focus group narratives. The study concluded that earlier pubertal maturation led to strained peer relationships among preadolescent girls. This article recommends that forums to educate children on the stages of development and how to handle each of them be incorporated in the curriculum, to prepare girls for pubertal maturation whenever it occurs.

Abstract (sommario):

This study analyzed the oral narrative abilities of Caucasian males between the ages of 8.5 and 13 years who had been identified as aggressive. Language skills of aggressive preadolescent Caucasian males and a comparison group were examined by comparing the composite scores from the Test of Language Development-Intermediate (TOLD-I), a standardized test of expressive and receptive language, and its five subtests; narrative language measures of mean length of utterance (ML LS), number of different words, and number of total words; and social-cognitive measures coded as providing setting, plot, and outcome. For narrative samples, the boys constructed an oral narrative based on the wordless picture book Frog, Where Are You? (Mayer, 1969). Results indicate that the aggressive boys did not differ from the comparison group on the composite score of the TOLD-I. The aggressive boys were also significantly different from the comparison group on MLU, a measure of syntactic complexity. In their narratives, the aggressive boys provided fewer pieces of information to create the setting of the story for listeners than did the boys in the comparison group. Information from this study may be helpful in planning programs for children identified as displaying aggressive behaviors.

Abstract (sommario):

In athletics, strength plays a special role, given that its development is focused on improving the speed of movement. The main form of expressing strength in athletics is speed-strength (explosive strength, take-off), which is representative for sprinting, jumping and throwing. Specialised studies have revealed that one of the most effective training methods used to develop explosive strength, also called explosive power, is the training based on plyometric exercises, but studies regarding the use of this method for the prepubertal age segment in athletic training are scarce. The purpose of this research is to investigate the degree of improvement in explosive strength in preadolescent athletes with the help of weekly plyometric training as compared to the control group. The research was carried out at the School no. 190 between 20 February and 17 June 2017. In order to conduct the experimental research, 42 athlete subjects of both genders, aged 11 to 13 years, were investigated. The experimental group was made up of 20 athletes, members of the Municipal Sports Club in Bucharest. The control group included 22 athlete subjects of both genders, who were trained by other coaches. Both groups performed four training sessions per week for 17 weeks. Analysing the results of the experiment, we can conclude that plyometric workouts contribute to the development of lower body strength in preadolescent athletes.

Abstract (sommario):

Background Reduced participation in physical activity and increased time spent in sedentary behavior are associated with overweight, chronic disease, and disability. In order to optimize recommendations and interventions to increase physical activity and reduce sedentary behavior in children with cerebral palsy (CP), knowledge of their physical activity and sedentary behavior is needed. Objectives The aim of this study was to describe light, moderate, and vigorous physical activity and sedentary behavior in preadolescent children with and without CP and compare physical activity and sedentary behavior between the 2 groups. Design This was a cross-sectional study of 33 children, aged 6 to 10 years, with CP (Gross Motor Function Classification System [GMFCS] levels I–III) and 33 age- and sex-matched children with typical development. Methods Physical activity was measured using the RT3 accelerometer over 7 days. Results Children with CP spent more time in sedentary behavior and accumulated less total activity, moderate activity, vigorous activity, and sustained bouts of moderate-to-vigorous activity (MVPA). They also accumulated a fewer number of bouts of MVPA and vigorous activity, despite spending a similar amount of time in each bout. Limitations The small number of children in GMFCS levels II and III did not allow for adjustment for GMFCS level when comparing physical activity between children with and without CP. Conclusions Preadolescent children with CP spent less time in moderate and vigorous activity and more time in sedentary behavior than children with typical development. Children with CP also accumulated less continuous MVPA and vigorous activity as a result of achieving fewer sustained bouts of MVPA and vigorous activity throughout the day.

Abstract (sommario):

Introduction: The aim of commencing treatment in younger age is to rectify the developing dento-alveolar, skeletal and muscular imbalances. With growing dependence on arch development and expansion, the pendulum is oscillating more towards the non-extraction treatment lately, in resolving constriction and crowding issues. Since, a limited number of attempts have been made for mandibular expansion, this study aimes to evaluate the effect of different modes and sites of loading on the expansion of preadolescent mandible using biomechanics. Study design: To address the research purpose, a total of 9 Finite Element models were simulated. Biomechanical response of the mandibular bone and dentition was analyzed under different loading conditions including site and mode, using the simulated FE models. Results: The values of displacement envisaged by the FE models, predict hybrid mode to offer substantial expansion of the mandibular bone as compared to tooth borne and bone borne. In addition, biomechanical effect of site II on mandibular expansion in terms of displacement on X-axis, was significant. Conclusion: In conclusion, the results of our study suggest hybrid mode at site II to be better option for true bony expansion in preadolescent mandible.

Abstract (sommario):

Awake craniotomies are a crucial tool for identifying eloquent cortex, but significant limitations frequently related to patient tolerance have limited their applicability in pediatric cases. The authors describe a comprehensive, longitudinal protocol developed in collaboration with a certified child life specialist (CCLS) in order to enhance patient experiences and develop resiliency related to the intraoperative portion of cases. This protocol includes preoperative conditioning, intraoperative support, and postoperative positive reinforcement and debriefing. A unique coping plan is developed for each prospective patient. With appropriate support, awake craniotomy may be applicable in a wider array of preadolescent and adolescent patients than has previously been possible. Future prospective studies are needed to validate this approach.

Abstract (sommario):

The present three-wave panel study ( N = 973, [Formula: see text] = 11.14) sought to advance the current literature on media internalization in preadolescence by examining triggers and consequences related to preadolescents’ media internalization and use of media for appearance information. We sought to examine whether (a) media internalization and use of media for appearance information could be explained by pubertal timing and peer appearance criticism, and (b) such media internalization and use of media for information could foster dysfunctional body image investment. Structural equation analyses showed that early maturation relative to peers and peer appearance criticism predicted preadolescents’ use of media for appearance information and media internalization, 6 months later. Such media use, in turn, predicted preadolescents’ development of dysfunctional appearance beliefs, 6 months later. These results highlight the importance for future studies to examine whether preadolescents’ reliance on appearance media stems from their need to cope with current body concerns.

Abstract (sommario):

Although previous studies have reported that proverb comprehension remains quite literal before adolescence, the results of the present study indicated that fourth graders performed well on a proverb comprehension task involving contextual information and a written multiple choice format. It was also found that performance on the proverb task steadily improved at least through the eighth grade and was significantly correlated to performance on a perceptual analogical reasoning task. The study contributes to the small but growing body of information concerning language development during the preadolescent and adolescent years and may have some important implications for the assessment of youngsters of this age range who have comprehension deficits that are troublesome, yet difficult to document.

Abstract (sommario):

Abstract X-linked severe combined immunodeficiency (XSCID) results from mutations in IL2RG, which encodes the common gamma chain (γc) shared by receptors for IL-2, 4, 7, 9, 15 and 21. XSCID is best treated with bone marrow transplantation (BMT) from an HLA-matched sibling. Patients lacking a matched sibling can benefit from a T-cell depleted haploidentical BMT, but some do not achieve adequate immune reconstitution. Ex vivo autologous hematopoietic stem cell (HSC) gene therapy may be an alternative to haploidentical BMT. In a French trial, 9 of 10 XSCID infants had immune reconstitution following ex vivo transduction of autologous HSC with a retroviral vector encoding γc. Selective development and expansion of T, NK and B cells from progenitors expressing γc was important to the success of this therapy. However, the 2 youngest patients, treated at 1 and 3 months of age, later developed T cell leukemias associated with retrovirus insertions that activated the LMO2 transcription factor. Young age at treatment might have had a role in the development of these adverse events. We have developed an XSCID gene transfer protocol as salvage treatment for older patients who have failed haploidentical BMT. An 11 year-old XSCID patient with no detectable engraftment from prior haploidentical BMTs had lymphocytopenia, growth failure, infections, chronic diarrhea and skin rashes. After G-CSF mobilization and harvest by apheresis, his purified autologous peripheral blood CD34+ cells were transduced daily for 4 days with GALV-MFGS-γc retrovirus in the presence of growth factors and Retronectin®. Eighty million cells/kg (80% CD34+; 40% γc transgene positive) were reinfused. At 1, 2 and 3 months after treatment, provirus marking by PCR of unseparated blood leukocytes was 1.4%, 2.3% and <0.01%, respectively. At 4.5 months, marking reappeared in lineages dependent on IL2RG expression: 0.5% in T cells, 0.1% in NK cells and 0.05% in B cells. This lineage-specific marking persisted at the same level at 6 months. LAM PCR showed polyclonal marking. T-lymphocytes have not yet increased above 300/μl. However, from 2 months after gene therapy the patient experienced a sustained improvement in well-being with resolution of lifelong diarrhea and rashes. No infections have occurred except one episode of otitis externa 3 months post therapy that resolved promptly to oral antibiotics. At six months submandibular lymph nodes were palpable for the first time in his life. Thymus size on chest CT images increased from 1.8 cm3 to 3.2 cm3. Additional follow up is necessary to know if gene marking and clinical improvement persist and if significant expansion of corrected lymphocytes occurs. Our preliminary results suggest that ex vivo retrovirus-mediated gene therapy, targeting CD34+ cells from peripheral blood, may benefit older children with XSCID who have failed haploidentical BMT.
