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.

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.

The purpose of this study was to create a valid and reliable instrument to evaluate theory-basedbeliefs towards physical activity among clergy members. Data were collected from 174 clergy that par-ticipated in a 15-item online and paper-based survey. Psychometric properties of the instrument includedconfirmatory factor analysis (construct validity), and cronbach’s alpha (internal consistency reliability).In addition, the stability (test-retest reliability) of each subscale was evaluated with a sub-sample of 30participants. Results show the instrument was both valid and reliable, and will be useful in future studiestargeting this population. Future implications are discussed.

Background: The physical activity has been indicated as an experience that can help achieve positive, self-oriented own body awareness. This awareness is an aspect that tends to get worse with age. Objective: Our study aims to verify the internal consistency of a questionnaire on physical awareness in a sample of Italian elders; a secondary objective is to measure if there is a relationship between physical awareness and perceived level of physical activity. Methods: Cross sectional study on a consecutive sample of elderly people was administered the “Physical Body Experiences Questionnaire simplified for active aging (PBE-QAG)”, inspired by the “Physical Body Experiences Questionnaire”, modified, simplified and adapted to be used in the elderly over 65. To elderly people the International Physical Activity Questionnaire. Cronbach’s alpha was also used to assess internal reliability of the total PBE-QAG. The factor structure was evaluated through Confirmatory Factor Analyses (CFAs). Results: The Cronbach’s alpha was 0.8 for the “body-mind relationship” scale, 0.81 for the “accepting your body” scale, 0.83 for the “awareness of physical skills” scale, and 0.65 for the “awareness of physical limits” scale. Cronbach’s alpha for the total PBE-QAG was 0.89. The CFA indicated a model with the 4 factors (CFI = 0.989, TLI = 0.984, RMSEA = 0.076). People who conducted physical activity assiduously or regularly and over 10 minutes showed a better score to the PBE-QAG than those who declared a sporadic activity and for “less than 10 minute”, respectively. Conclusion: Our study revealed that the PBE-QAG shows an excellent total internal consistency. In the Italian sample of elderly people the questionnaire shows the model with the 4 factors described in literature.

Objective: To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Design: Cross-sectional methodological study. Setting: Tertiary craniofacial medical center. Participants: Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). Interventions: All patients with VPI 8+ years old and their parents completed the Brazilian–Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. Main Outcome Measures: The VELO instrument was tested for internal consistency, test–retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). Results: The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test–retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (– r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity ( r > 0.7; P < .001). Conclusions: The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test–retest) and validity (discriminant, concurrent, criterion, and construct).

Abstract Background The absence of Respectful Maternity Care (RMC) deters mothers from seeking maternity care services. Given the importance of RMC and the lack of a standard tool for its assessment in Iran, the present study was conducted to translate and assess the psychometric properties of the RMC questionnaire in Iranian women. Methods Forward-backward method was used for translating the questionnaire from English into Persian. A total of 265 postpartum women entered the study by simple random sampling from public and private hospitals in Tabriz, Iran. The validity of the questionnaire was confirmed through the face, content and construct validity. Construct validity was assessed through exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were used to confirm the reliability of the questionnaire. Internal consistency was examined by measuring the Cronbach’s alpha in a sample of 20 mothers, and test-retest stability by calculating the Intraclass Correlation Coefficient (ICC) in the same group of mothers, who had completed the questionnaire twice with a two-week interval. Results The exploratory factor analysis led to the extraction of one factor. Item 12 was eliminated due to its low factor loading. X2/df was less than 5, and RMSEA was less than 0.08, which confirms the validity of this model. The Cronbach’s alpha coefficient was obtained as 0.93 and ICC (with 95% confidence interval) as 0.98 (0.96 to 0.99). Conclusion The results of the study demonstrated that the Iranian RMC scale can be used as a valid and reliable instrument to assess RMC in Iran.

Background: Curiosity is a personality characteristic, which fits with wellbeing and positive functioning. The objective of this study was to assess the construct validity of the Curiosity and Exploration Inventory II (CEI-II) in Indonesia.Design and Methods: The study included 256 undergraduate students who lived in Indonesia, mean age 19.8 years old. The CEI-II measures stretching and embracing using 11 items. The English version of CEI-II was translated into Bahasa. The Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were addressed to examine internal consistency reliability and the test-retest reliability. To evaluate construct validity, exploratory factor analysis (EFA) was used to assess factor structure and confirmatory factor analysis (CFA) was used to evaluate the structural model fit of the CEI-II Indonesia version.Results: The study showed Cronbach’s alpha for the internal consistency of the overall CEI-II Indonesia version was 0.77. The ICC for the test-retest reliability ranged between 0.753-0.829. EFA showed adequate with the Kaiser-Meyer-Olkin value of 0.86 and the Bartlett’s test of sphericity was statistically significant. CFA tested the second-order model with two-order factors and showed a model fit.Conclusions: The CEI-II Indonesia version indicated acceptable construct validity to evaluate curiosity in Indonesia.

AbstractThe objective of this study is to provide a valid and reliable Turkish version of the original Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). The SCHNOS questionnaire was translated from English to Turkish using standardized guidelines. Participants completed the questionnaire twice, with an interval of 7 to 10 days. Reliability and validity analyses were performed based on these answers. Differences between the rhinoplasty and control groups, the internal consistency of the instrument (Cronbach's alpha coefficient), and the strength of association between the two repeated measures (Pearson's correlation coefficient) were analyzed. Of the 188 included individuals (106 females, 82 males; mean age 28 ± 8.4 years), 97 were in the rhinoplasty group and 91 were in the control group. The mean total SCHNOS scores were 0.6 ± 0.4 and 29.4 ± 8.9 in the control and rhinoplasty groups, respectively, and there was a statistically significant difference in total scores between the groups (p < 0.001). The internal consistency reliability of the scale was found to be highly significant (Cronbach's alpha = 0.96, with a lower 95% confidence interval of 0.89). The test–retest correlation value was 0.95 for the total score, and each item had a strong test–retest correlation, ranging from 0.92 to 0.96. The Turkish version of the SCHNOS is a valid and reliable scale for evaluating both functional and cosmetic outcomes in Turkish-speaking patients undergoing rhinoplasty.

During the last 25 years researchers have proposed a number of conceptual frameworks to measure the various functions of instructional leadership. One of the most frequently used frameworks is the Principal Instructional Management Rating Scale (PIMRS). Despite the great number of studies employing the PIMRS, evidence for its reliability and validity is relatively limited. In addition, we still don’t know much about the extent to which this instrument could be used in diverse demographic and cultural educational settings. This study explores the content, face, and construct validity, reliability and internal consistency of the PIMRS in the Chinese educational system. A total number of 311 teachers from five middle schools in the Haidian District of Beijing participated in the study. The data were analysed using Confirmatory Factor Analysis (CFA). On an overall basis the results provided support for the face, content, and construct validity, reliability and internal consistency of the PIMRS. However, six out of the 50 items had to be removed to reach satisfactory fit indices. Implications of the findings in relation to the importance of evaluating the measuring properties of research instruments are discussed and, finally, suggestions for future studies are provided.

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility. Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS. Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity. Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.
