Recent research on attributional complexity with college student samples has indicated that mild and moderate depression are associated with increased attributional complexity but more severe depression may be related to decreased attributional complexity. The present study examined levels of attributional complexity in clinically depressed patients and normal controls. The results confirmed that severe depression is associated with reduced attributional complexity. The results are discussed in terms of the need for a multidimensional model of attribution and depression that incorporates individual differences in variables such as attributional complexity.
