“…Based on the results of Griffiths study, Cronbach's alpha and 3 month test–retest were reported 0.70 and 0.71, respectively [ 22 ]. The validity and reliability of the Persian version of the D-Lit questionnaire was investigated in the Tehrani study [ 24 ]. Based on exploratory factor analysis, 5 factors with eigenvalues greater than 1 were extracted, accounting for 56.30% of the variance (F1: Knowledge of the psychological symptoms, F2: Knowledge about the effectiveness of available treatment methods, F3: Knowledge about cognitive-behavioral symptoms, F4: Knowledge about taking medications and their side effects, and F5: Knowledge of severity of disease) [ 24 ].…”

Background This study was designed and conducted to determine the status of depression literacy (D-Lit) and its relationship with the quality of life across the Iranian population. Methods This cross-sectional study was conducted in 2020 among 1382 participating from the general population in Gonabad, Iran. Participants were selected and recruited using a multistage sampling method. Data were collected using three sets of questionnaires (demographic section, D-Lit scale, and quality of life questionnaire). Data were analyzed by SPSS software version 24 and using independent samples t- test, Chi-square test, One-way ANOVA, and Pearson correlation. Results Based on the results, the mean (± standard deviation) of D-Lit and quality of life were 44.14 (± 4.69) and 35.81 (± 5.17), respectively. Based on the results of Pearson correlation coefficient, there was a significant positive correlation between D-Lit and quality of life (r = 0.104, p < 0.001). D-Lit was significantly higher in those who reported having consulted with a psychiatrist compared with those who did not (p < 0.001). Participants with a family history of mental illness and those whose family members were referred to a psychologist for psychological issues had significantly higher levels of D-Lit than others (p < 0.001). Conclusion Based on the results of this study, some D-Lit projects should be improved. Also, the results revealed that D-Lit is a potential factor that can affect people's mental health status and enhance their quality of life. Therefore, it is necessary to develop appropriate educational programs to enhance D-Lit in the community and ultimately improve the quality of life in the community by reducing mental illness.

“…The study showed that two of the 33 cases that entered the content analysis phase were eliminated by a factor loading below 0.35, and the questionnaire was confirmed with 31 items. The results of the psychometric properties of depression literacy (D-Lit) in the Iranian community showed that only one question was eliminated in the confirmatory factor analysis stage, and D-Lit was confirmed with 21 questions ( 36 ).…”

IntroductionAnxiety disorder is one of the most common mental disorders. This cross-sectional research aimed to determine anxiety literacy (A-Lit) psychometric properties among the Iranian population in 2022.MethodsThis research was conducted on 690 people in Iran in 2022. In this study, people were selected by proportional stratified sampling, and the validity and reliability of the A-Lit designed by Griffiths were assessed. Validity of A-Lit was assessed by face validity, content validity, and confirmatory factor analysis. Reliability of A-Lit was evaluated by the McDonald’s omega coefficient, Cronbach’s alpha coefficient, and test– retest. In analytical sections, the tests of One-way ANOVA, Chi-squared test, and independent samples t-test were used.ResultsThe rates of S-CVI/Ave and CVR for A-Lit were 0.922 and 0.774, respectively. In confirmatory factor analysis, three items were deleted because the factor loading was less than 0.4, and goodness-of-fit indexes (Some of goodness-of-fit indexes: χ2/df = 4.175, GFI: 0.909, RMSEA = 0.068, PCFI = 0.745, AGFI = 0.883) were confirmed as the final model with 19 items. For all items, the Cronbach’s alpha coefficient was 0.832, the McDonald’s omega coefficient was 0.835, and the intraclass correlation coefficient was 0.874. According to the results of this study, 1.3% (n = 9) did not answer any questions correctly and 8.4% (n = 58) were able to answer 1–6 questions correctly. Approximately 72% (n = 495) were able to answer 7–12 questions, and eventually only 18.6% (n = 128) were able to answer 13 questions and more. There was a significant relationship between sex, age group, occupation status, marital status, and get information related to mental illness with A-Lit level (p < 0.05).ConclusionThe Persian version of A-Lit was confirmed with 19 items, and this scale is a reliable tool for measuring A-Lit in the general population. The results also showed that a few people have a higher level of anxiety literacy and that educational and intervention programs need to be designed and implemented for the public population.

“…D-Lit scale: This scale was created and evaluated by Griffiths et al ( 42 , 43 ), and Cronbach's alpha calculated as 0.70 ( 42 ). The validity and reliability of the D-Lit were assessed by Tehrani et al in the Iranian population, and the Cronbach's alpha coefficient of the D-Lit was 0.890 ( 44 ). This scale has 21 questions and five subscales of knowledge about the effectiveness of available treatment methods (four questions); knowledge of psychological symptoms (five questions); knowledge about taking medications and their side effects (four questions); knowledge about cognitive-behavioral symptoms (six questions); and knowledge of disease severity with two questions.…”

BackgroundThis study was conducted to measure depression literacy (D-Lit) and mental health literacy (MHL) and to investigate their relationship with psychological status and quality of life among Iranian patients with type 2 diabetes mellitus (T2DM).MethodsThis cross-sectional study was conducted in 2021 among 400 patients with T2DM in Iran. Samples were selected using proportional stratified sampling. Data collection tools comprised a demographic questionnaire, measures of MHL and D-Lit, the diabetes quality of life (DQOL) scale, and the DASS-21. After confirming the normality of the data using the Kolmogorov-Smirnov test, parametric statistical tests (such as one-way ANOVA, independent samples t-test, and Chi-Square) were used to investigate the relationship between the variables using SPSS v22 software. The results of continuous quantitative data are reported in the form of means and standard deviations, and qualitative data are reported in the form of absolute and relative frequencies.ResultsIn this study, 10.25% of the participants (n = 41) had severe depression, while 36.75% (n = 147) experienced severe anxiety. The mean (standard deviation) of MHL was 80.92 (9.16) from 130 points. Of the participants, only 1.7% (n = 7) did not answer any questions correctly on the D-lit scale, and only 5.8% (n = 23) were able to answer 15 questions or more correctly on the D-lit. MHL had a significant negative correlation with depression (r = −0.236), anxiety (r = −0.243), and stress (r = −0.155) (P < 0.001). There was a positive and significant correlation between MHL and D-Lit (r = 0.186) (P < 0.001). D-Lit had a significant negative correlation with depression (r = −0.192), anxiety (r = −0.238), and stress (r = −0.156) (P < 0.001). There was a positive and significant correlation between the ability to recognize disorders (r = 0.163), knowledge of self-treatment (r = 0.154), and DQOL (P < 0.001). Depression (r = −0.251), anxiety (r = −0.257), and stress (r = −0.203) had a significant negative correlation with DQOL (P < 0.001).ConclusionMHL and D-Lit levels were found to be inadequate in patients with T2DM. These low levels of MHL and D-Lit among patients with T2DM were associated with higher levels of anxiety, depression, and stress, as well as a lower quality of life. Therefore, designing and implementing preventive programs to improve the mental health of patients with T2DM can help prevent mental disorders and ultimately improve their quality of life.
