Development and Validation of a Short Questionnaire on Dietary and Physical Activity Habits for Patients Submitted to Bariatric Endoscopic Therapies

Abstract Purpose Individuals with obesity frequently regain weigh after endoscopic bariatric therapies (EBT) unless they adhere to healthy habits. The objective was to create and validate a short, self-administered questionnaire (EMOVE) to assess healthy dietary and physical activity (PA) habits’ adherence to be used in clinical practice. Materials and Methods In this prospective, unicentric study, 463 patients completed the short, Spanish EMOVE questionnaire, to be validated following the Medical Outcome Trust Criteria. Conceptual and measurement model, reliability (internal consistency and test–retest [subgroup of 93 patients]), construct validity, responsiveness, interpretability, and burden were evaluated. Patients enrolled from January 2017 through August 2018 and auto-filled the EMOVE at baseline and at 3, 6, and 12 months. Results Patients submitted to intragastric ballon for 6 and 12 months or POSE were 82.7% women with a mean age of 42.7 years, and a mean BMI of 37.1 kg/m2. Four factors were extracted with exploratory factor analysis related to intake frequency, portions and proportions, time and place of eating, and physical activity. EMOVE showed adequate internal consistency (α = 0.73), very good test–retest (r = 0.91, CI: 0.86–0.94; p < 0.001), moderate construct validity of dietary (r = 0.24, CI: 0.11–0.37, p < 0.001), and PA habits (r = 0.44, CI 0.30–0.58; p < 0.001). Stable responsiveness, with correlations from 0.29 to 0.39 (p < 0.001) between the EMOVE scores and the % of total weight loss at 3, 6, and 12 months. Participants categorized as having good or excellent habits (score ≥ 30 points) lost significantly more weight (p < 0.05). Finally, the administration burden was 2.96 min. Conclusion The EMOVE is a useful tool in Spanish language to easily assess the level of adherence to healthy dietary and PA habits to be used routinely in clinical practice. Graphical abstract

Background:Psychosocial factors have been related to physical activity (PA) and are used to evaluate mediation in PA interventions.Methods:Brief theory-based psychosocial scales were compiled from existing measures and evaluated. Study 1 assessed factor structure and construct validity with self-reported PA and accelerometry in overweight/obese men (N = 441) and women (N = 401). Study 2 assessed 2-week reliability and internal consistency in 49 college students.Results:Confirmatory factor analysis indicated good fit in men and women (CFI = .90; RMSEA = .05). Construct validity was supported for change strategies (r = .29–.46), self-efficacy (r = .19–.22) and enjoyment (r = .21–.33) in men and women, and for cons in women (r = –.19 to –.20). PA pros (r = –.02 to .11) and social support (r = –.01 to .12) were not supported for construct validity. Test-retest reliability ICCs ranged from .49–.81. Internal consistency alphas ranged from .55–.90. Reliability was supported for most scales with further testing needed for cons (alphas = .55–.63) and enjoyment (ICC = 49).Conclusions:Many of the brief scales demonstrated adequate reliability and validity, while some need further development. The use of these scales could advance research and practice in the promotion of PA.

OBJECTIVE: Assess the reliability and validity of the Exercise Benefits/Barriers Scale (EBBS) in the elderly. METHODS: The reliability was assessed by internal consistency (Cronbach's alpha) and by the test-retest Kendall's W. To verify the construct validity it was used a correlation between the EBBS results and the personal and clinic variables. RESULTS: The Cronbach's alfa of the EBBS was 0.94. The test-retest value was 0.60. The variables that presented association with the EBBS were: level of education (p = 0.02), practice of physical activity (p = 0.0001), with whom one resides (p= 0.032) and lifestyle (p= 0.0001). CONCLUSION: The statistical analysis revealed that the translated version of the EBBS is valid and reliable however, its use is recommended in different scenarios due to regional differences in Brazil, in order to have the validity of the instrument widely exploited.

Abstract Background The IPEN International Physical Activity and Environment Network Adolescent project was conducted using common study protocols to document the strength, shape, and generalizability of associations of perceived neighborhood environment attributes with adolescents’ physical activity and overweight/obesity using data from 15 countries. Countries did not use identical versions of the Neighborhood Environment Walkability Scale for Youth (NEWS-Y) to measure perceived neighborhood environment attributes. Therefore, this study derived a measurement model for NEWS-Y items common to all IPEN Adolescent countries and developed a scoring protocol for the IPEN Adolescent version of the NEWS-Y (NEWS-Y-IPEN) that maximizes between-country comparability of responses. Additionally, this study examined between- and within-country variability, and construct validity of the NEWS-Y-IPEN subscales in relation to neighborhood-level socio-economic status and walkability. Methods Adolescents and one of their parents (N = 5714 dyads) were recruited from neighborhoods varying in walkability and socio-economic status. To measure perceived neighborhood environment, 14 countries administered the NEWS-Y to parents and one country to adolescents. Confirmatory factor analysis was used to derive comparable country-specific measurement models of the NEWS-Y-IPEN. Country-specific standard deviations quantified within-country variability in the NEWS-Y-IPEN subscales, while linear mixed models determined the percentage of subscale variance due to between-country differences. To examine the construct validity of NEWS-Y-IPEN subscales, we estimated their associations with the categorical measures of area-level walkability and socio-economic status. Results Final country-specific measurement models of the factor-analyzable NEWS-Y-IPEN items provided acceptable levels of fit to the data and shared the same factorial structure with five latent factors (Accessibility and walking facilities; Traffic safety; Pedestrian infrastructure and safety; Safety from crime; and Aesthetics). All subscales showed sufficient levels of within-country variability. Residential density had the highest level of between-country variability. Associations between NEWS-Y-IPEN subscales and area-level walkability and socio-economic status provided strong evidence of construct validity. Conclusions A robust measurement model and common scoring protocol of NEWS-Y for the IPEN Adolescent project (NEWS-Y-IPEN) were derived. The NEWS-Y-IPEN possesses good factorial and construct validity, and is able to capture between-country variability in perceived neighborhood environments. Future studies employing NEWS-Y-IPEN should use the proposed scoring protocol to facilitate cross-study comparisons and interpretation of findings.

Abstract. This study aimed at developing and validating a new instrument to facilitate late adolescents and young adults to choose a higher education major. For the main study, the sample consisted of 6,215 late adolescents and young adults ( Mage = 19.50, SD = 1.89, 42.3% female). After rational scale construction based on the RIASEC model of Holland (1997) , several statistical analyses were conducted. In four studies, structural validity, internal consistency, and construct validity were examined. Our analyses showed that adequate structural validity, internal consistency, and construct validity were established. A 7-factor structure was found, in which the investigative domain split into two subscales. The overall results suggested that the new instrument is reliable and valid as an orientation instrument in applied settings in secondary and higher education.

Abstract Background Students suffer from a decrease in physical activity during their education period. This lower level of activity could affect, through various paths, their academic performance, mental health and satisfaction with life. In this study, we assume that vigor, a positive affect variable, would act as a mediating variable in the above relationship, and thus, we propose an instrument for evaluating vigor in academic contexts. To attain this aim, the factorial validity and reliability of the proposed vigor scale for students is tested (Study 1), along with its construct validity (Study 2). Methods In Study 1, 707 undergraduates (59.7% women) responded to the vigor scale adapted for students to test factorial validation (through confirmatory factor analysis) and obtain reliability indicators. In Study 2, 309 undergraduates (55.3% women) completed a questionnaire measuring physical activity, mental health, satisfaction with life, vigor and academic performance to test a structural model of the relationships between the variables to obtain construct validity. Results A measurement model with three related factors, each representing one dimension of vigor, optimally fit the data (S-Bχ2 = 231.54; df = 50; CFI = 0.95; NNFI = 0.93; SRMR = 0.07; RMSEA = 0.07 [0.06–0.08]), and the reliability indices were adequate (Study 1). In Study 2, the mediational model confirmed a complete influence of physical activity on satisfaction with life, academic performance and mental health levels through the levels of vigor of the students, with optimal adjusting values (S-Bχ2 = 108.82; df = 62; p < 0.001; CFI = 0.92; NNFI = 0.90; SRMR = 0.05; RMSEA = 0.05 [0.03–0.06]). Conclusions Proposing an instrument such as the Shirom-Melamed Vigor Measure for students allows the opening of a research venue that is focused on the study of positive affects in academic contexts, as well as the testing of the physical activity pathways of action in obtaining positive results.

In this article, we present the results of our efforts to develop and test a scale to operationalize and measure a neighborhood-level indicator of coercive sexual environments (CSEs), a construct emerging from our earlier work on safety and sexual threats among young girls living in chronically disadvantaged neighborhoods. Data for this study come from a survey of 124 adult and 79 youth respondents living in public housing in Washington, D.C., and participating in the Housing Opportunities and Services Together Demonstration, a multisite project testing the feasibility and effectiveness of place-based, dual-generation case management models to improve outcomes for vulnerable families. Our psychometric analysis indicates that the CSE scales we developed for adults and youth have high internal consistency. Together with our analyses of construct validity, the present findings suggest that CSE is a unitary construct that may be an important factor to include in models of neighborhood processes and risk.

Abstract Objectives The objective of this study was to assess the reliability and construct validity of the SNAP-Ed Youth Behavior Survey (YBS). Methods SNAP-Ed is a USDA program responsible for administering nutrition and physical activity education to SNAP-eligible children. The SNAP-Ed YBS is a 12-item program evaluation questionnaire pertaining to child food and physical activity behaviors and knowledge. There are 7 behavior questions (2 relate specifically to fruit and vegetable intake; scalar) and 5 knowledge questions (binomial). A demographic survey and the YBS was administered to 58 children attending a USDA Summer Food Service Program (SFSP) site where SNAP-Ed programming was occurring. Reliability was assessed using Cronbach's Alpha test for internal consistency. Skin carotenoid level was selected as the gold standard for assessing construct validity. Resonance Raman Spectroscopy (RRS) intensity was used to determine skin carotenoid levels. Construct validity was determined by comparing YBS fruit and vegetable behavior scores with skin carotenoid levels via Pearson Correlation coefficients. Results Mean age of participants was 8.43 ± 0.25 years, 92.86% were white, and mean RRS intensity was 26,717 counts. Alpha coefficients for internal consistency for behavior and knowledge questions were 0.66 and 0.20, respectively. There was an inverse relationship between fruit and vegetable responses and RRS intensity counts. Conclusions Results from this pilot demonstrate that the YBS is a reliable tool for assessing child behaviors, but not knowledge; validity of the fruit and vegetable intake questions was not observed. Future research should be conducted to confirm findings from this study to assure use of reliable and valid assessment tools in SNAP-Ed. Funding Sources USDA SNAP-Ed.

Barriers To Physical Activity

Abstract Background Pregnancy can affect the amount of physical activity that women engage in, so ensuring adequate physical activity in pregnant women can be a challenge. Therefore, there is a need to explore and identify barriers to physical activity in this population. Consequently, this study was conducted in order to develop and validate a scale to assess barriers to physical activity in pregnant populations. Methods The study was conducted in two phases. During phase 1, a comprehensive review of the most relevant literature from electronic databases on barriers to physical activity was carried out and appropriate scale items were extracted using a deductive approach. During phase 2, the psychometric properties of the extracted scale items were determined using face, content and construct validity, internal consistency and stability. Qualitative and quantitative face validity was assessed via face-to-face interviews with 30 and 10 pregnant women, respectively. To confirm the qualitative and quantitative content validity, 10 experts in the field of research and instrument design were invited to complete the resulting scale. To assess construct validity, the scale items were further tested among 320 pregnant women attending perinatal clinics at health centers in Ilam, Iran, where data were collected via continuous sampling. The internal consistency and stability of the study were measured by Cronbach’s alpha and intra-class correlation coefficient (ICC), respectively. Results Following a review of the relevant literature, 48 items for the BPAPS were extracted. Subsequent to the assessment of face and content validity, the number of items was reduced to 38. Through a subsequent exploratory factor analysis, the number of items dropped further to 29. These items were then structured under four major factors. Finally, the internal consistency and stability of the scale was confirmed by a Cronbach alpha coefficient of 0.824 and a test-retest reliability score of 0.87. Conclusion Findings show that the 29-item scale to assess barriers to physical activity in pregnant populations is a valid and appropriate instrument.
