Abstract

Objective: The aim of the study was to evaluate the validity and reliability of the Turkish version of Depression Literacy Questionnairre (D-LIT-Questionnaire).

Methods: The study is a methodological research conducted with Eskişehir Osmangazi University students. D-LIT-Questionnaire was developed by Griffiths et al. The final shape of the D-LIT-Questionnaire was created by the translation-back translation method. Turkey’s Health Literacy Scale-32 (THLS-32) was used for criterion validity. A questionnaire was applied to 40 medical faculty students in two weeks intervals to evaluate the discriminant validity and test-retest reliability of the scale. Statistical Package for the Social Sciences (version 15.0) and Lisrel 9.3 (Student’s version) were used to analyze the data. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Spearman correlation analysis were performed to evaluate the validity of the D-LIT-Questionnaire. Internal consistency and test-retest correlation was used to evaluate the reliability of the scale. Statistical significance was accepted as p<0.05.

Results: The mean of age of 204 students in the study group was 20.2±2.3 years. The Kaiser-Mayer-Olkin value of the scale was 0.69 and the Barlett test result was p<0.001 and the data were found to be suitable for factor analysis. It was observed that factor loads in EFA were above 0.30. The fit indices of the scale in CFA were found at acceptable levels. The median score of the students of Faculty of Medicine [15 (0-19)] was higher than the students of Faculty of Arts and Sciences [9 (0-16)] (p<0.001). The D-LIT-Questionnaire and THLS-32 were found to be positively correlated (r=0.199, p=0.046). The Cronbach’s alpha of the D-LIT-Questionnaire was calculated as 0.71. There was a strong positive correlation between the test-retest scores of the D-LIT-Questionnaire (r=0.720, p<0.001).

Conclusion: It is observed that the D-LIT-Questionnaire is valid and reliable for measuring D-LIT-Questionnaire in individuals aged 18 and over.
