Low-income depressed older adults with psychiatric comorbidity: secondary analyses of response to psychotherapy and case management.

OBJECTIVE

This study examined the influence of comorbid anxiety and personality disorders on depression treatment response in 67 low-income older adults.

METHODS

Participants were randomized to clinical case management, cognitive-behavioral group therapy, or both for 6 months. Outcomes were assessed at baseline, post-treatment, and 6 and 12 months after treatment.

RESULTS

Dropout and depression diagnoses were similar across groups. Participants with comorbidity had more depressive and anxiety symptoms at most time points; degree of improvement did not differ significantly. Of participants with personality disorder, none met criteria at post-treatment (three relapsed by 12-month follow-up).

CONCLUSIONS

Findings suggest depressed low-income elders with anxiety or personality disorders can be retained and benefit from depression treatment, but may require additional interventions to achieve similar levels of depressive symptoms.
