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.

AbstractObjectiveTo translate, culturally adapt, and psychometrically evaluate the Spanish version of the “Scale for End-of Life Caregiving Appraisal” (SEOLCAS).MethodObservational cross-sectional study. Convenience sample of 201 informal end-of-life caregivers recruited in a southern Spanish hospital. The reliability of the questionnaire was assessed through its internal consistency (Cronbach's α) and temporal stability (Pearson's correlation coefficient [r] between test-retest). The content validity index of the items and the scale was calculated. Criterion validity was explored through performing a linear regression analysis to evaluate the SEOLCAS’ predictive validity. Exploratory factor analysis was used to examine its construct validity.ResultsThe SEOLCAS’ reliability was very high (Cronbach's α = 0.92). Its content validity was excellent (all items’ content validity index = 0.8–1; scale's validity index = 0.88). Evidence of the SEOLCAS’ criterion validity showed that the participants’ scores on the SEOLCAS explained approximately 79.3% of the between-subject variation of their results on the Zarit Burden Interview. Exploratory factor analysis provided evidence of the SEOLCAS’ construct validity. This analysis revealed that two factors (“internal contingencies” and “external contingencies”) explained 53.77% of the total variance found and reflected the stoic Hispanic attitude toward adversity.Significance of resultsThe Spanish version of the SEOLCAS has shown to be an easily applicable, valid, reliable, and culturally appropriate tool to measure the impact of end-of-life care provision on Hispanic informal caregivers. This tool offers healthcare professionals the opportunity to easily explore Hispanic informal end-of-life caregivers’ experiences and discover the type of support they may need (instrumental or emotional) even when there are communicational and organizational constraints.

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.

Objective To translate the Stroke Rehabilitation Motivation Scale (SRMS), developed to evaluate the motivation level of stroke patients during rehabilitation, into the Korean language and to verify the reliability and validity of the Korean version of SRMS (K-SRMS).Methods The K-SRMS was developed following a structured process that included translation, verification, compromise assessment, reverse translation, feedback, and final correction. K-SRMS reliability was evaluated by performing internal consistency and test–retest analyses. The reliability test was conducted in 50 stroke patients. Its validity was assessed by comparing the K-SRMS with the scale and performing exploratory factor analysis. The validity test was conducted in 102 stroke patients.Results The test–retest analysis showed good reliability, and the internal consistency of the K-SRMS was similar to that of the original version for all, except 4, items. Thus, these 4 items were excluded, and then the validity test was conducted. Pearson correlation analysis demonstrated that the K-SRMS score was significantly correlated with the BAS total score (Pearson r=0.207, p<0.05). In the exploratory factor analysis, K-SRMS items were categorized into 7 groups (factors), and factors 1 and 4 showed mutual concordance with K-SRMS subscales, including intrinsic motivation factors and amotivation, respectively.Conclusion The newly developed K-SRMS showed good reliability and validity. It could also be used as a tool to objectify the degree of motivation for rehabilitation among stroke patients in clinical care and research.

The purpose of this study was to develop a tool for community-based health organisations (CBHOs) to evaluate the preparedness in biohazards concerning epidemics or bioterrorism. We searched concepts on partnerships of CBHOs with health systems in guidelines of the Centers for Disease Control and Prevention and literature. Then, we validated the researcher-made tool by face validity, content validity, exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and criterion validity. Data were collected by sending the tool to 620 CBHOs serving under supervision of Iran’s ministry of health. Opinions of health professionals and stakeholders in CBHOs were used to assess face and content validity. Factor loads in EFA were based on three-factor structure that verified by CFA. We used SPSS V.18 and Mplus7 software for statistical analysis. About 105 health-based CBHOs participated. After conducting face validity and calculating content validity ratio and content validity index, we reached 54 items in the field of planning, training and infrastructure. We conducted construct validity using 105 CBHOs. Three items exchanged between the fields according to factor loads in EFA, and CFA verified the model fit as Comparative Fit Index, Tucker-Lewis index and root mean square error of approximation were 0.921, 0918 and 0.052, respectively. The Cronbach’s of the whole tool was 0.944. Spearman correlation coefficient confirmed criterion validity as coefficient was 0.736. Planning, training and infrastructure fields are the most important aspects of preparedness in health-based CBHOs. Applying the new assessment tool in future studies will show the weaknesses and capabilities of health-based CBHOs in biohazard and clear necessary intervention actions for health authorities.

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.
