Specificity of cognitive change following cognitive therapy for depression was assessed in 39 depressed inpatients who completed either a standard inpatient treatment (pharmacotherapy and milieu management) or the standard treatment plus cognitive therapy. Following treatment, patients in both groups endorsed fewer dysfunctional cognitions on 2 of 4 measures of cognitive distortion. Compared with patients receiving only the standard treatment, patients also receiving cognitive therapy reported less hopelessness and fewer cognitive biases at posttreatment and 6- and 12-month follow-up assessments and fewer dysfunctional attitudes at the 6-month follow-up. Treatment effects for dysfunctional cognitions were found even though the treatment groups did not differ in depression severity, suggesting that results did not reflect state-dependent differences between treatments secondary to difference in depression.
