Gains in employment status following antidepressant medication or cognitive therapy for depression.

Abstract

Depression can adversely affect employment status. To examine whether there is a relative advantage of cognitive therapy or antidepressant medication in improving employment status following treatment, using data from a previously reported trial. Random assignment to cognitive therapy (n = 48) or the selective serotonin reuptake inhibitor paroxetine (n = 93) for 4 months; treatment responders were followed for up to 24 months. Differential effects of treatment on employment status were examined. At the end of 28 months, cognitive therapy led to higher rates of full-time employment (88.9%) than did antidepressant medication among treatment responders (70.8%), χ(2) 1 = 5.78, P = 0.02, odds ratio (OR) = 5.66, 95% CI 1.16-27.69. In the shorter-term, the main effect of treatment on employment status was not significant following acute treatment (χ(2) 1 = 1.74, P = 0.19, OR = 1.77, 95% CI 0.75-4.17); however, we observed a site×treatment interaction (χ(2) 1 = 6.87, P = 0.009) whereby cognitive therapy led to a higher rate of full-time employment at one site but not at the other. Cognitive therapy may produce greater improvements in employment v. medication, particularly over the longer term.
