BACKGROUND: Given the increased rate of divorce, it is important to analyse the characteristics of divorce applicants. The theory of planned behaviour (TPB) can provide a suitable framework to predict, explain, and/or change the behaviours. In Iran, no instrument can be found, based on health education models, to investigate divorce petition filing as a behaviour.AIM: This study was conducted to design a questionnaire on withdrawal of divorce petition based on the TPB and estimate its validity and reliability.MATERIAL AND METHODS: A qualitative study was conducted in 27 participants involved in the divorce process using directed content analysis. The face and content validity of 58 items, drawn from the qualitative study, were evaluated by 10 experts. The reliability was estimated using Cronbach’s alpha coefficient. The SPSS version 16 was used to analyse data.RESULTS: Estimates of the face and content validity (quantitative and qualitative), revealed that of the 58 items, 48 were valid based on four of the constructs of the TPB. Cronbach’s alpha coefficient was also derived greater than 0.6.CONCLUSION: The designed questionnaire, whose validity and reliability was confirmed in this study, can be used in similar studies. However, the social and cultural differences and their related effects should be considered.

Background and PurposePoor dietary practices are linked to many chronic diseases. The purpose of this validation study was to develop a psychometrically sound instrument that can be administered by health practitioners to measure dietary barriers.MethodsThe Dietary Health Status (DHS) instrument, designed to measure dietary barriers is comprised of items in the National Health and Nutrition Examination Survey-What We Eat in America datasets. Content validity was established for DHS using an expert review process. Principal component analysis (PCA) was then used to assess validity and reliability as determined by Cronbach's alpha values.ResultsThe PCA supported a 10-component solution, explaining 61% of the total variance. Cronbach's alpha was .67 for the entire instrument, ranging from .55 to .87 for the 10 subscales.ConclusionResults suggest the instrument had sufficient construct and internal validity. This exploratory study is an important first step in validating the DHS instrument.

Abstract Background: The assessment of sex addiction among different populations requires a valid and reliable tool. Since the Bergen–Yale Sex Addiction Scale (BYSAS) was not available in Iran, this study aimed to evaluate the validity and reliability of the Persian version of BYSAS. Method: After translation/back-translation procedure, a total of 756 Iranian men and women completed the BYSAS. The structural validity of this tool was evaluated by exploratory and confirmatory factor analysis. An expert panel review also examined content validity of the items. Psychometric properties of the scale including validity, reliability (internal consistency [Cronbach’s alpha]) and test-retest) and factor structure were assessed. Results: Content Validity Index (CVI) and Content Validity Ratio (CVR) scores for BYSAS were 0.75 and 0.62, respectively. Data analysis demonstrated satisfactory internal consistency (Cronbach’s alpha ranging from 0.88 to 0.89). Discussion: Study findings suggest that the BYSAS is a valid and reliable instrument for assessing sex addiction among Persian speaking adults. Replication of research findings is needed to expand the BYSAS for clinical and non-clinical Iranian populations.

Factors attributing to the behavior of non-prescription used of antibiotics in Indonesia setting have not been identified yet. The availability of effective and efficient instrument or method to identify the attributing factors might be the cause of non-optimal identifying process. The objective of present study was to develop instrument, i.e questionnaire, to identify factors contributing to the behavior of non-prescription used of antibiotics. The questionnaire was developed based on factors identified on published scientific literatures. Face and content validity were conducted by having the experts’ judgement, while the construct validity was conducted by using the Spearman Correlation Test. Reliability was tested by using Cronbach’s alpha test. There were 14 rating and 8 multiple answer questions in the questionnaire that could be classified unto 5 domains. After conducting the validity and reliability test, the final questionnaire had a R value 0.276-0.628 and Cronbach’s alpha 0.833. This valid and reliable questionnaire could be used to portray the attributing factors of non-prescription used of antibiotics in larger area, therefore, the most appropriate intervention could be planeed based on the identified factors.

Objective: This study aimed to develop the Sports Injury Prevention Awareness Scale (SIPAS) and to determine its validity and reliability for use with the Turkish population. Materials and Methods: This methodological study was initiated after approval by the local ethics committee. After a review of the literature, a pool of 31 items was developed. The items were organized into a 5-point Likert-type scale (Scale v.1), and the content validity of this pilot-scale was assessed using the Lawshe method, for which expert opinion was used to determine content validity ratio (CVR) and content validity index (CVI). Subsequently, the pilot-scale was applied to a sample of at least 10 times the number of items. Participants' descriptive information, and responses were recorded electronically (Google Forms). Data were analyzed and the validity and reliability of the scale were assessed using SPSS v.23 and AMOS v.24. Results: The content validity of the scale (Scale v.1) was assessed using opinions from 18 experts. Items that did not meet the minimum CVR threshold were eliminated (k=2). The remaining 29-item scale (Scale v.2) had a CVI of 0.696 and was applied to a total of 379 participants (147 males, 38.8%; 232 females, 61.2%) with a mean age of 29.2±11.3 years. From Scale v.2, a total of 11 items were removed due to reducing Cronbach's alpha coefficient (k=5), lack of variables (k=1), or cross-loading between factors (k=5). The remaining 18 items (Scale v.3) explained 59.7% of the variance. Analyses revealed four factors with eigenvalues λ>1.0. The reliability of Scale v.3 was demonstrated with a Spearman-Brown reliability coefficient of 0.778, a Guttman split-half reliability coefficient of 0.772, and a Cronbach's alpha reliability coefficient of 0.884. Scale v.3 satisfied the goodness-of-fit indices in confirmatory factor analysis. Conclusions: The 18-item four-factor (health status, environmental factors and equipment, exercise session, exercise program) Sports Injury Prevention Awareness Scale is valid and reliable for use with Turkish individuals aged 13-66 years.
