[The Validity and the Reliability of Turkish Version of the Self-Stigma of Depression Scale]

In this study, we aimed to the Self-Stigma of Depression Scale (SSDS), which evaluates self-stigmatization that can prevent both treatment consultation and compliance by depressed patients run Turkish adaptation, validity and reliability study of.

The study included a total of 173 subjects consisting of 131 outpatients of the Psychiatry Polyclinic with past or recent major depression disorder (MDD) diagnosis and 42 non-depressed outpatients consulting the Geriatrics Polyclinics for other medical complaints. Each participant was evaluated with the Structured Clinical Interview for DSM IV Axis I Disorders (SCID-I), the Standardized Mini Mental State Examination (MMSE), the Turkish Self-Stigma of Depression Scale (SSDS-TR) and the Beck Depression Inventory (BDI). The MDD patients were further evaluated with the Internalized Stigma of Mental Illness (ISMI) scale. Test-retest reliability of the SSDS-TR was assessed with 27 participants 8-12 weeks after the first test. All analyses were carried out using the IBM-SPSS Statistics version 25 and the IBM SPSS AMOS version 25.

In the exploratory factor analysis, the factor structure of SSDS TR differed from the original form. The structural validity of the 4-factor model formed after excluding one problematic item was tested by confirmatory factor analysis and proven to meet the goodness of fit criteria. The Cronbach's α coefficient of the SSDS-TR was 0.847, and a moderate correlation (r=0.436 p=0.023) was obtained by the test-retest analysis. The SSDS-TR scores moderately correlated with the ISMI scores (r=0.485, p<0.001) and weakly correlated with the BDI scores (r=0.246, p<0.001).

The SSDS-TR formed by excluding one item from the original scale was demonstrated to be a valid and reliable psychometric tool and is expected to fill a gap in the assessment of self stigmatization of MDD patients in Turkey.
