Interrater Reliability of the Canadian Occupational Performance Measure (COPM) Within Geriatric Rehabilitation
Summary
The Canadian Occupational Performance Measure (COPM) shows moderate interrater reliability in geriatric rehabilitation. Therapists should enhance COPM administration training to improve consistency for older patients.
Area of Science:
- Occupational therapy
- Geriatric rehabilitation
- Clinical assessment tools
Background:
- The Canadian Occupational Performance Measure (COPM) is increasingly utilized in geriatric rehabilitation (GR).
- Concerns exist regarding the consistency of COPM administration by occupational therapists (OTs) in this complex population.
- Assessing interrater reliability (IRR) is crucial for ensuring consistent application of the COPM in GR.
Purpose of the Study:
- To evaluate the interrater reliability (IRR) of the Canadian Occupational Performance Measure (COPM) within routine geriatric rehabilitation (GR) settings.
- To quantify the consistency of COPM administration between occupational therapists (OTs) for elderly patients.
- To identify potential challenges in COPM scoring within GR practice.
Main Methods:
- Two occupational therapists (OTs) independently administered the Canadian Occupational Performance Measure (COPM) to patients aged 65+ in two GR wards.
- Interrater reliability was assessed by calculating the overlap in prioritized occupational performance problems.
- Intraclass correlation coefficients (ICCs) were computed for COPM-Performance and COPM-Satisfaction scores.
Main Results:
- Twenty-six geriatric patients (mean age 79) with orthopaedic and neurological conditions participated.
- A 65% overlap was found in the 112 prioritized occupational performance problems identified by the two OTs.
- The ICC values for COPM-Performance and COPM-Satisfaction were moderate, at 0.566 and 0.567, respectively.
Conclusions:
- The Canadian Occupational Performance Measure (COPM) demonstrates moderate interrater reliability (IRR) in geriatric rehabilitation (GR).
- A moderate percentage of overlapping prioritized occupational performance problems suggests potential inconsistencies in COPM administration.
- Occupational therapists (OTs) in GR should be aware of these scoring challenges and prioritize training to improve COPM administration consistency.
