Abstract

Objective: To demonstrate the reliability and validity of the Turkish version of the Structured Interview Guide for Hamilton Depression Rating Scale Seasonal Affective Disorder (SIGH-SAD-T) which is an interview that contains the broadest depressive symptoms. Method: Interview guide was first translated into Turkish by three psychiatrists, secondly back-translated by a linguist into English, and then confirmed by the psychiatrists who developed the original SIGH-SAD. The study was carried out with 90 patients diagnosed as major depressive disorder according to DSM-IV criterias who attended the out-patient department. SIGH-SAD-T was administered by two psychiatrists concurrently and Montgomery-Asberg Depression Rating Scale (MADRS) was applied in addition. For reliability, internal consistency and interrater correlation; and for validity, concurrent validity with MADRS were subjected to the data. Results: Mean age of the sample was 37.1±12.2 and 78.9% of the sample were females. Atypical features were present in the 32.2% of the group. In reliability analyses, in the whole group Cronbach alpha coefficient of HDRS with 17 items was 0.75, and of the whole SIGH-SAD-T was 0.64. In the atypic group, the Cronbach alpha coefficient was found to be 0.53 for the atypical items, and in the classical depression group it was calculated as 0.72 for the 17-item scale. Inter-rater correlation was between 0.86-0.91 (p<0.0001). In validity analyses, correlation with MADRS and HDRS-17 was 0.77 and with MADRS and SIGH-SAD-T was 0.72 (p<0.0001). Conclusion: As expected, atypical items contrasted to the total score of the whole scale. In conclusion, the Turkish version of the Structured Interview Guide for Hamilton Depression Rating Scale Seasonal Affective Disorder (SIGH-SAD-T) was shown to be both reliable and valid.
