Both treatment groups were pooled and divided into 2 groups, “working ability recovered” or “working ability not recovered,” based on working ability at the end of the study. Patients were also divided into 4 subgroups by the presence or absence of previous depressive episodes and working ability. Main outcome measures included baseline demographics and clinical characteristics, and the 17-item Hamilton Rating Scale for Depression (HAM-D17).Results: Comparison between “working ability recovered” (n=122) and “working ability not recovered” (n=91) showed that the percentage of patients with complications and psychotherapy at baseline, and baseline HAM-D17 total, insomnia, somatic, and anxiety scores, were significantly different. The results of subgroup analyses were mostly the same as the results analyzed by working ability alone. Although statistical differences were observed for some outcome measures, the differences at baseline, except use of psychotherapy, may not be applicable clinically, and there were no specific trends observed that could predict working ability.Conclusion: This post hoc analysis suggested that most baseline clinical characteristics, including the presence or absence of previous depressive episodes, were not predictive of working ability recovery. However, the use of psychotherapy in parallel with antidepressant monotherapy may be positively associated with working ability recovery. All outcome measures improved over time, reinforcing the importance of continuous treatment and observation to improve and accurately judge working ability in patients with MDD and PPS.Keywords: ability to work, antidepressants, depressive disorder, major, observational study, painful physical symptoms
