Memory for therapy in bipolar disorder and comorbid insomnia

Area of Science:

• Psychiatry
• Psychology
• Sleep Medicine

Background:

• Bipolar disorder and insomnia frequently co-occur.
• Effective psychotherapy requires patient engagement and retention of therapeutic content.
• Limited research exists on patient recall of therapy content in this population.

Purpose of the Study:

• To assess patient recall of therapy content session-to-session.
• To investigate the association between therapy content recall and treatment outcomes in bipolar disorder patients with insomnia.

Main Methods:

• Thirty individuals with bipolar disorder and comorbid insomnia participated in a randomized controlled trial.
• Patients received either cognitive behavior therapy for insomnia (CBTI-BP) or psychoeducation (PE).
• Recall was measured by patient-reported therapy points compared to therapist-recorded points; outcomes assessed using standardized sleep and quality of life measures.

Main Results:

• Patients recalled between 19.6% and 36.9% of therapy points.
• Higher numbers of recalled therapy points correlated positively with improved insomnia severity and quality of life.
• Cognitive behavior therapy for insomnia group recalled more therapy points than the psychoeducation group.

Conclusions:

• Patient memory for therapy content is generally poor.
• The quantity of recalled therapy content is positively associated with treatment success.
• Interventions aimed at improving memory for therapy may enhance treatment outcomes for bipolar disorder with comorbid insomnia.
