The D-92 Scale of Depression (Krizmanić and Kolesarić, 1994) is the original Croatian psychological instrument for the measurement of the intensity of depression symptoms in the clinical and general adult population. Relying on Beck’s theory of emerging and maintaining symptoms of depression, the scale includes issues that question the attitude of the respondent toward himself, toward other people and toward the future. The scale is intended to estimate the severity of the disorder of a clinically diagnosed group. In this paper, discrimination, reliability and validity of D-92 scales and the ability to differentiate subjects within clinically diagnosed groups with depressive disorder, anxiety disorders and other mental disorders, have been tested. The study was conducted on a sample of 210 clinically diagnosed subjects (127 males and 93 females) with depressive, anxiety and other mental disorders. Subjects completed the cognitive ability test, the Crown-Crisp Experiential Index and the D-92 depression scale. Descriptive indicators show very good sensitivity of the scale in differentiating persons according to the number and intensity of the symptoms of depression in the selected clinical sample in the workability assessment situation (M = 66,65, SD = 9,70). Internal consistency (α = 0,89) showed high reliability of the D-92scale. Convergent validity is supported by a high correlation with the depression subscale in CCII Experiential Index (r = 0,62). Divergent validity was not confirmed, results showed high correlations with a measure of free-floating anxiety (r = 0,62) and somatic concomitants of anxiety (r = 0,55). Univariate analysis of variance shows in the character of depression between groups with different diseases indicates that the intersection of the distribution of results is high and the respondents can belong to all groups of the disease.
