Designing a Questionnaire to Measure Factors Affecting Utilization of Services for Diabetics in Health Centers Based on Social Marketing Model

Background: The needs and demands of patients as one of the pillars of marketing in the health field require the right tools to identify consumers’ requests. Objectives: This study was conducted to develop a tool to evaluate services utilization behavior by type 2 diabetics in health centers based on a social marketing model (ie, 7 Ps). Methods: This study was conducted in two main stages. The first stage was performed with the aim of the initial design of the tool (ie, a questionnaire) through a literature review and professionals’ opinions. The second stage was performed to confirm the validity and reliability of the prepared questionnaire in the previous stage through calculating the impact score, content validity index (CVI), content validity ratio (CVR), and Cronbach’s alpha coefficient. The study participants included 8 academic and executive experts in the field of health and diabetes, 30 diabetic patients to calculate the impact score, and 50 patients with diabetes to calculate the Cronbach’s alpha through test-retest. The data were analyzed using SPSS software (version 18). Results: According to the results of the first stage of the study, a questionnaire with 46 items was designed. After determining the formal and content validity quantitatively and qualitatively, 8 items were deleted, and a questionnaire with 38 items was provided. Finally, the validity and reliability of the instrument were confirmed (CVI = 0.91; CVR = 0.92; intraclass correlation coefficient = 0.89; Cronbach’s alpha = 0.92). Conclusions: This questionnaire with confirmed validity and reliability helps analyze the diabetics’ behavior and specifies the reasons for the acceptance or rejection of the services of the diabetes unit by patients. Therefore, it can be used in health centers providing services for diabetics.

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.

Introduction It is required to have validated instruments in health science students that identify unhealthy habits and assess the impact of educational interventions and programs aimed at promoting a healthy lifestyle. Objective To evaluate the validity and reliability of an instrument to measure medical students' lifestyles. Methods A lifestyle questionnaire was developed using the Delphi technique by a group of experts. The final questionnaire was applied to 332 students of the School of Medicine of the Ricardo Palma University in 2017. A preliminary examination was carried out to assess preconditions for construct validity—including the correlation matrix, the Kaiser Meyer Olkin statistic, and the Bartlett sphericity test. Factor analysis was used for construct validity, and the possible resulting factors were extracted through the principal component analysis. Cronbach's alpha coefficient was calculated to assess the instrument reliability. Results In this study, 41.6% of participants were men with a mean age of 20 years (standard deviation = 3). The preconditions for the factor analysis were a Kaiser Meyer Olkin coefficient = 0.773 and a significant Bartlett sphericity test. For the 47 items of the final questionnaire, the factor analysis showed an explained variance of 56.7% with eigenvalues greater than one. Cronbach's alpha was 0.78. The final questionnaire could assume values between -23 to 151 points. Based on a cut point of 71 points, the prevalence of students with an unhealthy lifestyle was 73.6%. Conclusion The developed instrument has acceptable validity and reliability to measure lifestyle in medical students. For external validation, studies in other university populations are suggested.

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.

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.

Abstract Background Diabetic foot self-care refers to a group of self-management behaviors that can reduce the incidence of foot ulcers and amputations. It is necessary to have a valid and reliable standard tool to measure foot self-care in diabetic patients. This study aimed to evaluate the psychometric properties of the Persian version of the Diabetic Foot Self-Care Questionnaire of the University of Malaga, Spain (DFSQ-UMA) in Iran. Methods This cross-sectional study was conducted with 407 diabetic patients who were selected using a convenient sampling method. Construct validity was assessed by exploratory (with 207 patients) and confirmatory (with 200 patients) factor analyses. Internal consistency was calculated using Cronbach’s alpha and McDonald’s omega coefficients. Results In the exploratory factor analysis, three factors with eigenvalues of 3.84, 2.41, and 2.26 were extracted that together explained 56.74% of the total variance of diabetic foot self-care. A Cronbach’s alpha of 0.865 was found for the total instrument. Conclusions The Persian version of the DFSQ-UMA has good validity and reliability, and given its good psychometric properties, it can be used in future studies.
