Problem-Solving Therapy Reduces Suicidal Ideation In Depressed Older Adults with Executive Dysfunction.

Area of Science:

• Geriatric Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Older adults with major depression and executive dysfunction are at increased risk for suicidal ideation.
• Existing therapies may not adequately address the complex needs of this demographic.
• The efficacy of Problem Solving Therapy (PST) versus Supportive Therapy (ST) in reducing suicidal ideation in this population requires investigation.

Purpose of the Study:

• To compare the effectiveness of Problem Solving Therapy (PST) against Supportive Therapy (ST) in reducing suicidal ideation.
• To investigate the impact of patient characteristics, including age, sex, and cognitive load, on changes in suicidal ideation.

Main Methods:

• Secondary analysis of data from a randomized clinical trial involving 221 participants aged 65 and older.
• Participants diagnosed with major depression and executive dysfunction were randomized to receive 12 weekly sessions of either PST or ST.
• Suicidal ideation was assessed using the suicide item of the Hamilton Depression Rating Scale, with blinded raters.

Main Results:

• 61% of participants reported suicidal ideation at baseline.
• The PST group demonstrated a significantly higher rate of improvement in suicidal ideation (60.4%) compared to the ST group (44.6%) at 12 weeks (p = 0.031).
• Logistic regression indicated significantly greater reductions in suicidal ideation for PST recipients at both 12 weeks (OR: 0.50) and 36 weeks (OR: 0.50) post-treatment.

Conclusions:

• Problem Solving Therapy (PST) is an effective intervention for reducing suicidal ideation in older adults with major depression and executive dysfunction.
• PST shows promise as a suicide prevention strategy for at-risk elderly individuals.
• Further research can explore the long-term effects and specific patient characteristics influencing treatment outcomes.
