Cognitive Behavioral Therapy for Late-Life Depression (CBTlate): Results of a Multicenter, Randomized,...

Area of Science:

• Geriatric Psychiatry
• Clinical Psychology
• Psychotherapy Research

Background:

• Late-life depression (LLD) is a significant public health concern.
• Evidence-based psychotherapeutic interventions for LLD are crucial, yet large-scale trials are limited.
• Cognitive behavioral therapy (CBT) is a recognized treatment for depression, with specific adaptations for older adults (LLD-CBT).

Purpose of the Study:

• To evaluate the efficacy of a specialized cognitive behavioral therapy for late-life depression (LLD-CBT) compared to a supportive unspecific intervention (SUI).
• To assess treatment outcomes in a specialist psychiatric outpatient setting for patients aged 60 years and older with moderate to severe depression.

Main Methods:

• A randomized, controlled, parallel-group trial conducted across 7 German trial sites.
• 251 participants (≥60 years) with moderate to severe depression were randomized to LLD-CBT or SUI.
• Primary outcome: change in depression severity (Geriatric Depression Scale - GDS) at end of treatment. Secondary outcomes included anxiety, sleep, and quality of life.

Main Results:

• 229 participants provided primary outcome data; no significant difference in GDS score change between LLD-CBT and SUI groups (p = 0.287).
• Both LLD-CBT and SUI groups showed significant improvements in depression, anxiety, and sleep ratings after 8 weeks and at 6-month follow-up.
• Quality of life also improved in both treatment arms over the study period.

Conclusions:

• LLD-specific CBT and supportive unspecific treatment offer comparable clinical benefits for moderate to severe late-life depression.
• The study did not find evidence supporting the superiority of LLD-CBT over SUI in this patient population.
• Both interventions are viable options for managing depression in older adults in specialist psychiatric settings.
