Abstract:

It was aimed to test the Turkish validity and reliability of the Self Reporting Questionnaire-20 (SRQ-20) developed by WHO in order to scan the mental disorders in the young group aged 18 years and over. The study is a methodological type research conducted on students between the ages of 18-25, who are studying at Eskişehir Osmangazi University Faculty of Medicine, in September-October 2021. SRQ-20 was translated into Turkish by three foreign language experts using the translation-back translation method. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and discriminant validity were tested for construct validity. General Health Questionnaire (GHQ) was used for criterion validity. To assess reliability, Cronbach's Alpha and item-total correlation coefficient were calculated. The stability of the scale was evaluated with the test-retest method. The item scores of the lower and upper 27% groups were compared to evaluate item discrimination. The study group consisted of 325 people, including 164 women (50.5%) and 161 men (49.5%). The mean age was 21.2±2.1 years. It was seen that the Turkish version of SRQ-20 consisted of three sub-dimensions. The factor loads were between 0.408 and 0.779. The total explained variance was 44.2%. Chi-square/SD=1.58, SRMR=0.08, RMSEA=0.042, CFI=0.971 and NNFI=0.967 were found among the goodness-of-fit indices. It was found 0.875 for the overall Cronbach Alpha scale. Item-total correlation coefficients ranged from 0.323 to 0.613. There was a difference between the scores of the lower and upper 27% groups from the SRQ-20. A strong positive correlation was detected between SRQ-20 and GSA. It was found that students who reported that they had a physician-diagnosed mental disorder had higher scores on the SRQ-20 than the others. As a result of test-retest application, the Spearman correlation coefficient between the SRQ-20 scores obtained from the two applications was found to be 0.792. It was concluded that the SRQ-20 is a valid and reliable scale that can be used in the young age group of 18 and over in the Turkish population in order to scan the mental disorders.
