Summary
Poor patient recall of treatment information impacts outcomes. This study developed the Memory Support Rating Scale (MSRS) to measure provider memory support, finding it reliable and valid for improving patient memory in cognitive therapy.
Area of Science:
- Psychology
- Clinical Psychology
- Psychiatry
Background:
- Patient memory for treatment information is often poor, negatively affecting clinical outcomes.
- Existing memory support techniques aim to improve recall, but a standardized measure for provider use is lacking.
Purpose of the Study:
- To develop and validate the Memory Support Rating Scale (MSRS), an observer-rated tool to quantify memory support provided during therapy sessions.
- To assess the psychometric properties of the MSRS.
Main Methods:
- Developed an 8-item observer-rated scale (MSRS) using exploratory factor analysis.
- Assessed interrater and test-retest reliability with 7 coders across 171 sessions.
- Evaluated convergent and discriminant validity by correlating MSRS scores with patient recall and cognitive therapy quality (CTRS).
Main Results:
- The MSRS demonstrated high interrater and test-retest reliability.
- Scores on the MSRS were significantly higher in the cognitive therapy plus memory support (CT + MS) group compared to cognitive therapy as-usual (CT-as-usual).
- MSRS scores showed positive association with patient recall (convergent validity) but no association with cognitive therapy quality (discriminant validity).
Conclusions:
- The MSRS is a reliable and valid instrument for measuring memory support provided by clinicians during cognitive therapy.
- The scale can differentiate between conditions with and without explicit memory support interventions.
- The MSRS has potential to enhance the assessment and delivery of memory support in clinical practice.
