Introduction: Suicide and suicide attempts are among the most important indicators of mental health in the world. In this research, the validity and reliability of Literacy of Suicide Scale (LOSS) was examined in general people over the age of 18. Methods: This cross-sectional psychometric study was conducted in 2022 among 952 general population in Iran. Participants were selected by two methods of proportional stratified sampling and simple random sampling. The internal consistency of the tools was assessed using Cronbach's alpha coefficient, and McDonald omega coefficient. Also, test-retest reliability was checked by Intraclass Correlation Coefficient (ICC). Results: In the confirmatory factor analysis section, the factor loading of all questions were above 0.4 and one questions were deleted and final model with four factors and 25 questions was confirmed (Some of goodness-of-fit indexes: AGFI = 0.910, RMSEA = 0.050, IFI = 0.901, and χ2/df = 3.333). For all questions, the Cronbach's alpha coefficient was 0.859, McDonald omega coefficient was 0.866, and ICC was 0.895. Finally, the Persian long version of LOSS was approved with 25 items and four subscales: causes/triggers (9 items), risk factors (7 items), signs and symptoms (5 items) and treatment/prevention (4 items). Conclusion: The Persian long version of LOSS with four subscales and 25 items is an appropriate tool to investigate the state of suicide literacy in the public population. [ABSTRACT FROM AUTHOR]

In this cross sectional study, the subjects were 390 students. The findings revealed two components of spiritual transcendence and spiritual openness and also the questions that had high factor loadings with these components are largely consistent with the findings of the scale's authors. Construct validity and reliability were ascertained and the goodness of fit was determined for the Spiritual Transcendence Scale (KMO: 91). The ensemble of the model's coefficients are x2/sd = 418.39, RMESEA =.68, NFI =.95, CFI =.97. Results showed that the exploratory two-factor analysis (EFA) of this research is good-fitted without the need for modification. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to investigate the psychometric properties of the Persian version of Diabetes Health Literacy Scale in type 2 diabetic patients. Method: This cross-sectional study was conducted in 2021 in 1040 patients with type 2 diabetes in eastern Iran. Participants was selected by proportional stratified sampling method. The validity of DHLS was investigated through qualitative face validity, qualitative content validity, and structural validity (exploratory factor analysis and confirmatory factor analysis). The reliability of DHLS was checked by Cronbach's alpha coefficient, McDonald omega coefficient, and test–retest. Results: In exploratory factor analysis, 3 factors with eigenvalues greater than 1 were extracted, explaining 68.57% of the variance. These factors entered the confirmatory factor analysis, none of the questions were removed, and all questions had factor loading above 0.4. Cronbach's alpha coefficient and McDonald omega coefficient of DHLS were 0.919 and 0.922. Also, the Intraclass correlation coefficient of DHLS was 0.957. Finally, the DHLS was approved with 14 questions and the three subscales of Informational Health Literacy (6 items), Numerate Health Literacy (5 items), and Communicative Health Literacy (3 items). Conclusions: DHLS with 14 questions and the three subscales is a valid and reliable tool for examining diabetes health literacy in people with type 2 diabetes. [ABSTRACT FROM AUTHOR]

Background: The prevalence of depression in society is increasing and there is a need for a suitable tool to assess the health literacy of people in this field. This study was conducted to evaluate the psychometric of the Iranian version of the depression literacy (D-Lit) questionnaire. Methods: This cross-sectional study was conducted on 845 participants with a proportional stratified sampling method. First, the translation and cultural adaptation of questionnaire was performed. Then, the validity of D-Lit was assessed by face validity, content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). The reliability of D-Lit was assessed by the Cronbach's alpha coefficient and McDonald omega coefficient. Results: Based on the results of EFA, 5 factors emerged with eigenvalues of greater than 1, which accounted for 56.30% of the variance. Based on the results of CFA, one question was deleted and the results of goodness fit indexes confirmed the model. Cronbach's alpha coefficient and McDonald omega coefficient for D-Lit questionnaire were 0.890 and 0.891, respectively. Finally, D-Lit questionnaire with 21 questions and 5 subscales of Knowledge of the psychological symptoms (5 items), Knowledge about the effectiveness of available treatment methods (4 items), Knowledge about cognitive-behavioral symptoms (6 items), Knowledge about taking medications and their side effects (4 items), and Knowledge of the severity of the disease (2 items) were confirmed. Conclusion: The results of this psychometric evaluation confirmed the Persian version of D-Lit questionnaire with 21 questions and 5 subscales is an appropriate tool for measuring people's literacy about depression.

Introduction: This research was conducted with the aim of evaluating the validity and reliability of Persian short version of the Literacy of Suicide Scale (LOSS) among the general population. Methods: This methodological study was conducted to evaluate the validity and reliability of Persian short form of LOSS among the general population, using a sample of 1175 participants in Iran, 2022. Participants were entered to study using method of proportional stratified sampling. The validity of Persian short form of LOSS was checked by four measures of validity: qualitative face validity, qualitative content validity, EFA (exploratory of factor analysis), and CFA (confirmatory factor analysis). The measure of reliability of Persian short form of LOSS was checked by three reliability of McDonald omega coefficient, ICC (Intraclass Correlation Coefficient), and Cronbach's alpha coefficient. Results: Based on the findings of EFA, 4 components with eigenvalues > 1 were extracted and these 4 factors were able to explain 57.96% of variance. In EFA section, only 1 question was deleted due to entry into the non -relevant sub –scale. Based on the results of CFA, all items had the factor loading greater than 0.4 and none of the items were removed at this stage. In CFA, based the results of goodness-of-fit indexes for example: χ2/df = 2.077, NFI: 0.957, IFI = 0.977, RMSEA = 0.030, GFI: 0.988, and PGFI = 0.569, the final mode was approved with 11 items and 4 factors. In this study for all items, Cronbach's alpha coefficient was 0.739, McDonald omega coefficient was 0.753, and ICC was 0.860. Finally, the Persian short form of LOSS was approved with 11 items and four dimensions of signs/ symptoms with 3 questions, the risk factors with 2 questions, treatment/ prevention with 2 questions, and causes/ triggers with 4 questions. Conclusion: The Persian short form of LOSS with 11 items and four subscales is a valid and reliable scale to survey the suicide literacy status in the general population. [ABSTRACT FROM AUTHOR]

Background: The health locus of control (HLC) can indirectly determine the health status. The current study aimed to assess the validity and reliability of Form C of the Multidimensional Health Locus of Control (MHLC-C) scale in pregnant women. Methods: 554 pregnant women participated in this cross-sectional study conducted in 2017; they referred to community health centers affiliated with Mashhad and Gonabad Medical Sciences Universities. Multi-stage random sampling was done. In this study, first, the questionnaire was translated into Farsi; then, face validity and construct validity were done through exploratory factor analysis, and concurrent criterion validity was also examined. Moreover, the reliability was assessed through internal consistency and stability methods. Results: The results of the exploratory factor analysis showed that the MHLC-C scale consisted of four subscales, i.e. Chance, Internal, Other People, and Doctors, which accounted for 51.18% of variance. The results of the reliability analysis showed an acceptable internal consistency for the scale (Cronbach's alpha coefficient for subscales from 0.62 to 0.90). Also, the test-retest results showed good stability for all subscales other than Doctors (P<0.05). The concurrent validity of Forms B and C of MHLC scale showed a positive and significant correlation between subscales. Conclusion: The results of this study showed that the MHLC-C scale had acceptable validity and reliability in pregnant women and is suggested as an applicable criterion for assessing individuals control beliefs with any medical or health-related condition in Iran.
