Abstract Objectives Valid and reliable instruments for the measurement of mindfulness are crucial for people living with HIV. However, there was no Myanmar version of such an instrument. Methods We adapted the English version of the 12-item Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) based on standard cross-cultural procedures. By randomly sampling methods, a sample of 248 eligible people living with HIV was contacted from a closed Myanmar Facebook group; 159 PLHIV completed the initial 12-item version of the adapted survey. Results Three items were removed due to low item-to-total correlations of the corrected item-total correlation as well as having infit and outfit mean squares outside the range of 0.6 to 1.4. After deleting the 3 items, the three-factor structure was confirmed by confirmatory factor analysis, which indicated good model fit. The resultant 9-item CAMS-R in Myanmar (CAMS-R-M-2) achieved good internal reliability (Cronbach’s α of 0.75 to 0.87, and the corrected item-total correlation ranged from 0.44 to 0.81). Construct validity of the scale was demonstrated by significant association with self-reported HIV stigma and social support levels (r = 0.63, and − 0.53). In Rasch analysis, the infit and outfit mean squares for each item ranged from 0.49 to 1.24, and the person reliability was 2.17 and the separation index was 0.83. Conclusions The 9-item CAMS-R-M-2 with a three-factor structure has good reliability and validity. Higher total scores and subscale score reflected greater mindfulness qualities in people living with HIV in Myanmar.

Full textAbstract:
The present study assessed whether selected item characteristics—difficulty for the group, corrected item-total correlation, cognitive level, and difficulty for the examinee—relate to judgment of item difficulty. Undergraduate students in two classes ( ns = 76, 43) identified what they believed were the five easiest and five most difficult items on a multiple-choice test. Statistically significant correlations were observed for difficulty for the group and the frequency that items were chosen as easy as well as with frequency of items chosen as difficult. Students performed significantly better on items they chose as easy than those chosen as difficult. Items chosen as easy more often called for simple, factual recall than did items chosen as difficult.

The main aim of research is to develop model and instrument psychological competencies scale (PCS) of 100 Meter Student Athletes. This research use a mixed methods approach. 1st Study, used a qualitative approach, identifying the constructs and dimensions of elite 100 meter runner student athletes. Using literature review and interview of 2 elite athletes and 2 coaches. The results of the first study is psychological competencies model consists of goal setting, goal setting, motivation, concentration, emotion regulation, focus, self talk, self confidence, and persistence. Another result is 10 items of multidimentional measure of PCS. Each items in the scale were responded on five point level. Leveling describes psychological abilities based on behavior. 2nd Study, using a quantitative approach, instrument validation and reliability testing. We recruited 50, age 18-22 years from 100 meters runner student athletes voluntarily participated in this study. We assessed construct validity by examining how well the measures discriminated groups expected to differ based on their competencies, using Corrected Item-Total Correlation with a minimum limit of 0.300 to be declared a valid item. We assessed internal consistency of PCS using the Cronbach Alpha coefficient. The result of Corrected Item-Total Correlation obtained results All items are valid because they have a Corrected Item-Total Correlation value greater than the minimum limit of 0.300. The internal consistency of the (Cronbach’s alpha coefficient) was 0.841. It can be concluded that PCS is valid and reliable for measuring for 100 meter runner student athlete.

ObjectivesTo translate the Organisational Readiness for Implementing Change measure into German and assess its psychometric properties.DesignCross-sectional psychometric study based on secondary analysis of baseline data from a shared decision-making implementation study.SettingThree departments within one academic cancer centre in Hamburg, Germany.ParticipantsFor comprehensibility assessment of the translated ORIC version, we conducted cognitive interviews with healthcare professionals (HCPs, n=11). Afterwards, HCPs (n=230) filled out the measure.Primary and secondary outcome measuresThe original English version of the ORIC was translated into German using a team translation protocol. Based on comprehensibility assessment via cognitive interviews with HCPs, the translated version was revised. We analysed acceptance (completion rate), factorial structure (exploratory factor analysis (EFA), confirmatory factor analysis (CFA), model fit), item characteristics (item difficulties, corrected item-total correlations, inter-item correlations) and internal consistency (Cronbach’s α).ResultsTranslation and cognitive testing of the German ORIC was successful except for item 10, which showed low comprehensibility as part of content validity in cognitive interviews. Completion rate was >97%. EFA and CFA provided a one-factorial structure. Item difficulties ranged between 55.98 and 65.32, corrected item-total-correlation ranged between 0.665 and 0.774, inter-item correlations ranged between 0.434 and 0.723 and Cronbach’s α was 0.93.ConclusionsThe German ORIC is a reliable measure with high completion rates and satisfying psychometric properties. A one-factorial structure of the German ORIC was confirmed. Item 10 showed limited comprehensibility and therefore reduces content validity of the measure. The German ORIC can be used to analyse organisational readiness for change as a precursor for implementation success of various interventions.

Abstract Background Housing-related control beliefs are associated with aspects of health among older people in general. Research on Parkinson’s disease (PD) focusing on perceptions of the home are rare and instruments capturing perceived aspects of home have seldom been used. Aims To evaluate psychometric properties of the external Housing-related Control Beliefs Questionnaire (HCQ) among people with PD. Methods The external HCQ were administrated to 245 participants with PD, (mean age = 69.9 years; mean PD duration = 9.7 years). External HCQ has 16-items, with five response options. The psychometric properties evaluated were data quality, structural validity (factor analysis), floor and ceiling effects, corrected item total correlations, internal consistency and construct validity (testing correlations with relevant constructs according to pre-defined hypotheses). Results Data quality was high. Structural validity showed a unidimensional construct with removal of two items. Homogeneity was questionable, but strengthened after the removal of the two items. For the 14-item version internal consistency was α = 0.78 and SEM 4.47. Corrected item total correlation ranged between 0.31 and 0.54 and no floor or ceiling effects. Significant correlations with relevant constructs supported the construct validity. Conclusions Taken together, the psychometric results suggest a 14-item version of the external HCQ to be sufficiently reliable and valid for use in the PD population. The results pave the way for further studies, using the HCQ to analyse how perceptions of control of the home may be associated with health among people ageing with PD.

Full textAbstract:
Persistent pain after surgery in breast cancer has a significant
impact on the patient’s survival. The value of escalating
research on breast cancer in Malaysia cannot be underestimated.
However, it is not known how many of these women experience
persistent pain after surgery. This study surveyed previously
unknown figures on prevalence, and explored the predictive
factors of persistent pain women with breast cancer in Malaysia.
There were three objectives. First, to assess the reliability of
the already established investigative tools, namely, the Brief
Pain Inventory, Distress Thermometer, and Resilience scale RS-14;
second, to survey the prevalence of persistent pain; and thirdly
to identify predictors of persistent pain in women after breast
surgery, using the above measures. A test and retest design with
no intervention and a recall period of 3 to 7 days was employed
for assessment of the investigative tools. A cross-sectional
study, with a prospective, correlational design, a retrospective
review of medical records was used to identify predictors of
persistent pain. These investigations were conducted in two
phases –Section A and Section B – using separate data sets,
with different inclusion and exclusion criteria. Participants
were recruited from the University of Malaya Medical Centre,
Malaysia. Descriptive statistics, a stepwise regression model for
reliability testing, Cronbach alpha, and factor analysis were
used. This study divided pain into categories 0 = no pain, 1–4
= mild pain, 5–6 = moderate pain, and 7–10 = severe pain.
Section A: The tools were found reliable. Section B: A total of
123 participants were recruited; 119 participants remained
because 4 of them did not meet the inclusion criteria. A total of
43% of the participants had persistent pain (n = 51). Pain
interfered with their work, mood, and sleep. Based on a “Yes”
answer for pain today (n = 51), data were analysed to determine
predictors. The results revealed three predictors: distress, B =
–.911, resilience, B = –.444, and pain interference, B =
.309. The model was statistically significant, F (3, 41, 44) =
13.827, R2 = 0.267, .381, .467), and adjusted R2 = .250, .351,
.467, p = 0.001. Significant P value ≤ .005. Pain prevalence
was 43% in this Malaysian population. This study provided
empirical evidence which is an important new knowledge to health
care systems, health care providers, policy makers, and future
research. The impact of persistent pain on work, mood, and sleep
are justifiable medical concerns. The results obtained and
identified predictors are catalysts for providing extra support
for breast cancer women after surgery. Ideally, all women with
breast cancer should have very good life satisfaction.

Full textAbstract:
A cross-cultural comparison can be misleading for two reasons: (1) comparison is made using different attributes and (2) comparison is made using different scale units. This chapter illustrates multiple statistical approaches to evaluating the cross-cultural equivalence of the research instruments: data distribution of the items of the research instrument, the patterns of responses of each item, the corrected item–total correlation, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and reliability analysis using the parallel test and tau-equivalence test. Equivalence is the fundamental issue in cross-cultural research and evaluation.

Full textAbstract:
This paper describes the development and validation of the Reasoning about P-values and Statistical Significance (RPASS) scale. The RPASS was designed to support future research on students’ conceptual understanding and misunderstanding of statistical significance and the effects of instructional approaches on this understanding. After expert content validation and testing, the 27-item RPASS-4 was administered across five introductory courses at California Polytechnic State University (N = 224). Respondents answered 16 of 27 items correctly, on average. This paper reports evidence of construct validity, both convergent and discriminant validity evidence (n = 56). However, internal consistency reliability was low (α = .42, N = 224). A subset of 15 items was identified with expected coefficient alpha of .66 by removing items with low corrected item-total correlations. Implications for future development and research are discussed.
