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.

Objective: To determine face, content, and construct validity, and internal consistency of ROL scale. Methods and Findings: A three-phase study was conducted. First, content analysis of the scale was carried out consulting 10 professional experts. Then, face validity was analyzed with 60 caregivers. Finally, construct validity was evaluated by performing an exploratory factor analysis (EFA) with 110 participants. Internal consistency of ROL scale was also assessed. Face validity of ROL scale reached a high acceptance index in three dimensions: role performance (0.97), role organization (0.98), and response to the role (0.98). Content validity showed coherence, clarity, and relevance of the scale. From factor analysis, three components emerged and were grouped in the same manner for varimax, quartimax, and equimax rotations. Cronbach's alpha was 0.816, which is an acceptable overall value. Conclusion: ROL scale makes objective the concept of role taking in family caregivers of people with chronic disease. It demonstrated to have acceptable reliability, and construct, face, and content validity to be used in the Colombian context. Keywords: Validation Study, Caregivers, Health Transitions, Chronic Disease.

Introduction: The preparedness of families for the disasters can set auspicious grounds for the preparedness of the whole society. In Iran health system, Household Disaster Preparedness Index (HDPI) that is composed of 15 items is applied for assessing the household preparedness in disasters. This study was conducted to investigate the reliability and validity of this index. Methods: In order to investigate the HDPI reliability, we two methods, namely internal consistency and stability determination, are. In order to investigate HDPI validity, we examined the face validity, content validity and construct validity. To do so, besides interviewing with the experts and family heads, 200 families were selected based on multistage cluster sampling method from amongst a study population that included the families in all the counties in Isfahan Province. Use has been made in content validity investigation of both qualitative and quantitative methods; and, in investigating the construct validity, exploratory factor analysis was the method of choice. Results: The amount of HDPI internal consistency was calculated 0.786 which is in an acceptable range. HDPI stability, as well, was computed 0.98 using the test-retest method which is also in an optimal level. Therefore, it can be stated that HDPI enjoys the required reliability. Investigation of HDPI face validity indicated that the families have problems in perceiving some of the items of this index. The experts presented suggestions for improving the HDPI content validity following the qualitative investigation of the content validity. In the investigation of the content validity ratio (CVR), all the items, except the ones numbered 1, 3 and 4 were in an acceptable range; however, the investigation of the content validity index (CVI) indicated that only the validity of the items numbered 12 and 13 was acceptable in terms of all the three scales of relevancy, clarity and simplicity. To determine the construct validity, we used exploratory factor analysis to extract five factors (subscales), namely reduction of vulnerability, planning for disasters, family empowerment, procurement of resources for disasters and specialized programs. The internal consistency of these subscales indicated that only the internal consistencies of the first and the second factors were in an acceptable range. Conclusion: The present study revealed that although HDPI was a reliable measure, it did not enjoy the required validity for assessing the household preparedness in disasters.

BACKGROUND: Internationally, many instruments have been designed to evaluate mental health knowledge; however, in pregnant women is very limited. AIM: Therefore, this study aimed to develop and validate a survey to measure the mental health knowledge of pregnant women. METHODS: In this cross-sectional study, 13 midwives attended the FGD and 10 pregnant women were invited for in-depth interviews to develop an item pool. The content validity was carried out by a panel of 6 experts. The face validity was performed with 5 pregnant women. Next, the construct validity test involved 150 pregnant women who were selected by stratified sampling from 13 public health centers in Surakarta, Indonesia. Analyses were conducted to check content validity, face validity, construct validity, internal consistency reliability, difficulty index, and exploratory factor analysis. RESULTS: A final 20-item Mental Health Knowledge Scale (MHKS) has a content validity index of 0.97 and a correlation value per item greater than the r-table (i.e., 0.1603). In addition, the MHKS has a Kuder–Richardson 20 reliability coefficient of 0.717. Furthermore, the difficulty index ranged from 0.39 to 0.82 which was considered in the good and acceptable category. Construct validity was confirmed using exploratory factor analysis KMO = 0.713, Bartlett’s test p < 0.001. CONCLUSION: Based on the findings, the final version of the MHKS was considered a valid and reliable tool. The instrument can be applied to measure the understanding of pregnant women about pregnancy depression. Further studies require adjustment items to other participants regarding mental health knowledge.

AbstractObjectiveThe present study aimed to develop and validate a nutrition knowledge questionnaire in a sample of French Canadians from the province of Quebec, taking into account dietary guidelines.DesignA thirty-eight-item questionnaire was developed by the research team and evaluated for content validity by an expert panel, and then administered to respondents. Face validity and construct validity were measured in a pre-test. Exploratory factor analysis and covariance structure analysis were performed to verify the structure of the questionnaire and identify problematic items. Internal consistency and test–retest reliability were evaluated through a validation study.SettingOnline survey.SubjectsSix nutrition and psychology experts, fifteen registered dietitians (RD) and 180 lay people participated.ResultsContent validity evaluation resulted in the removal of two items and reformulation of one item. Following face validity, one item was reformulated. Construct validity was found to be adequate, with higher scores for RDv. non-RD (21·5 (sd2·1)v. 15·7 (sd3·0) out of 24,P<0·001). Exploratory factor analysis revealed that the questionnaire contained only one factor. Covariance structure analysis led to removal of sixteen items. Internal consistency for the overall questionnaire was adequate (Cronbach’sα=0·73). Assessment of test–retest reliability resulted in significant associations for the total knowledge score (r=0·59,P<0·001).ConclusionsThis nutrition knowledge questionnaire was found to be a suitable instrument which can be used to measure levels of nutrition knowledge in a Canadian population. It could also serve as a model for the development of similar instruments in other populations.

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.

Background:One of the goals of nursing is to provide safe patient care and medical errors are one of the most important threats in this field.Therefore, the purpose of this study is to assess the status of error reporting culture and determine its relationship with demographic characteristics.Methods:This descriptive,analytical and cross-sectional study was carried out among 239 nurses of amiralmomenin and bouali hospitals. First,face validity and then content validity were performed by 15 nursing experts and the questionnaire was distributed and collected. The normal distribution of data was confirmed by Kolmogorov-Smirnov test. The reliability and construct validity were performed with Cronbach’s Alpha test and exploratory factor analysis by PCM.The status of reporting culture was determined by computing descriptive statistics and its relation with demographic variables with Pearson correlation test and logistic regression test with SPSS software version 16.Results:The content validity with CVR &CVI of 0.820 and 0.920 were confirmed. The reporting culture was favorable with a mean and standard deviation of 2.674 and 0.475.The reliability with Cronbach's alpha of 0.747 and the construct validity with a KMO of 0.727 and Significance of the Bartlett test were confirmed and 3 subscales were extracted. The relationship between age and work experience with the reporting culture with a correlation of 0.009 and 0.013 with a significant < 0.05 were rejected But with the variable of gender(=female) with a chance of 2.536 and the significant of 0.006 was confirmed.Conclusion:Developing a safety culture in hospitals by implementing various health programs improves the reporting culture,but the mental climate is undesirable and requires major steps to reduce worries and negative outcomes after reporting.The presence of female nurses in comparison with men improves the error reporting culture.Perhaps the main reason is patriarchy in Iranian culture.
