Abstract

Associations between major depressive disorder (MDD) and psychosocial functioning are incompletely understood across time and during continuation phase cognitive therapy (C-CT). We examined the validity of the Range of Impaired Functioning Tool (RIFT; [Leon, A.C., Solomon, D.A., Mueller, T.I., Turvey, C.L., Endicott, J., Keller, M.B., 1999. The Range of Impaired Functioning Tool (LIFE-RIFT): A brief measure of functional impairment. Psychol. Med. 29, 869–878.]) as a measure of psychosocial functioning and its relations to depressive symptoms in C-CT and assessment-only control conditions.
