Problem-solving therapy and supportive therapy in older adults with major depression and executive dysfunction:...

Area of Science:

• Geriatric psychiatry
• Clinical psychology
• Neuroscience

Background:

• Older adults with depression and executive dysfunction face significant disability and treatment resistance.
• Pharmacotherapy often proves ineffective for this demographic.

Purpose of the Study:

• To compare the efficacy of problem-solving therapy (PST) versus supportive therapy (ST) in reducing disability.
• To determine if improvements in depressive symptoms mediate the effect of PST on disability.
• To assess the long-term maintenance of treatment benefits.

Main Methods:

• A randomized controlled trial involving adults aged over 59 with major depression and executive dysfunction.
• Participants received 12 sessions of either modified PST or ST.
• Disability was measured using the World Health Organization Disability Assessment Schedule II.

Main Results:

• Problem-solving therapy (PST) demonstrated a more prominent reduction in disability at 9 and 12 weeks compared to supportive therapy (ST).
• The advantage of PST was more pronounced in patients with greater cognitive impairment and a history of more depressive episodes.
• Reductions in disability correlated with improvements in depressive symptoms, and PST's benefits persisted 24 weeks post-treatment.

Conclusions:

• Problem-solving therapy (PST) is more effective than supportive therapy (ST) for reducing disability in older depressed adults with executive dysfunction.
• The therapeutic gains from PST were sustained after treatment cessation.
• PST presents a viable alternative treatment for older patients with depression who are resistant to pharmacotherapy.
