[Cognitive behavioral therapy for depressed older outpatients--a controlled, randomized trial]

Area of Science:

• Gerontology
• Psychiatry
• Clinical Psychology

Background:

• Limited scientific evidence exists for psychotherapy effectiveness in elderly patients with depression.
• Depression in older adults is a significant public health concern requiring effective interventions.

Purpose of the Study:

• To compare the efficacy of cognitive behavioral group therapy (CBT) against a waiting list control for treating depression in older adults.
• To evaluate the impact of CBT on depressive symptoms at post-treatment and 6-month follow-up.

Main Methods:

• A controlled randomized trial involving 100 older adults diagnosed with depressive disorder.
• Participants were assigned to either CBT (N=65) or a waiting list (N=35) in a 2:1 ratio.
• Assessments were conducted at pre-treatment, 3-month post-treatment/waiting, and 6-month follow-up.

Main Results:

• Cognitive behavioral group therapy demonstrated superiority over the waiting list in reducing depressive symptoms at both post-treatment and follow-up.
• A statistically and clinically relevant improvement was observed, unaffected by antidepressant medication.
• Complete remission rates were significantly higher in the CBT group (36 patients) compared to the waiting list group (4 patients).

Conclusions:

• Cognitive behavioral group treatment is a well-accepted and successful intervention for depression in older adults.
• Waiting for treatment is associated with a lack of improvement and can lead to worsening depressive symptoms.
• The findings support the immediate implementation of CBT for elderly individuals experiencing depression.
