Psychometric properties and cut-off scores of the Beck Depression Inventory-II in Turkish adolescents.

ABSTRACT

The current study examined the psychometric properties and cut-off scores of the Beck Depression Inventory II in Turkish adolescents. A total of 503 non-clinical and 166 clinical adolescents participated in the study. Test-retest (r = .89) and internal consistency (alpha = .90) reliabilities, convergent validity (r = .81) and discriminant validities (r = .39, r = .49 and r = .42) were satisfactory. Exploratory factor analyses yielded two factors. The cut-off score for mild depression in Turkish adolescents was lower than that reported previously for adults. The findings are discussed in relation to those of previous studies conducted in other countries.
