Abstract

Objective: The aim of this study was to investigate the validity and reliability of the Affect Underpinned by Severity and Social Impairment Questionnaire (AUSSI) Turkish Form. Method: The study included 137 (117 female and 20 male) patients between 18 and 65 years of age who were diagnosed as major depressive disorder according to DSM IV diagnosis. Also 32 control subjects (25 female and 7 male) were included. All subjects completed Sociodemographic Information Form and Affect Underpinned by Severity and Social Impairment Questionnaire. The patients were also assessed by Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS) and Brief Disability Questionnaire (BDQ). For reliability Cronbach's coefficient and split-half reliability analyses were performed. For Validity Analyses, Factor Analyses was performed. Pearson correlation coefficient that between HDRS, HARS, BDQ and AUSSI were also measured. Results: Concerning the reliability of the scale, Cronbach's alpha coefficient was 0.897, Gutman Split-half coefficient was calculated by split half method as 0.862. Cronbach's alpha coefficient composed of 6 items for the first part was 0.801, and for the second part containing the 5 items was 0.857. In order to determine the construct validity of AUSSI, factor analysis was performed using varimax rotation method, and two factors (Affect Severity, Social Impairment) were obtained with Eigenvalue greater than 1.0. Also correlations of AUSSI total between BDQ (r=0.61, p<0.001), HDRS (r=0.74, p<0.001) and HARS (r=0.69 p<0.001) scores were significant. Conclusion: The Turkish version of the Affect Underpinned by Severity and Social Impairment Questionnaire was found to be valid and reliable in this study. AUSSI, allows on a scale to describe mood symptoms and social impairment and to follow up residual symptoms after treatment in patients with major depressive disorder.
