Relative importance of rehabilitation therapy characteristics on functional outcomes for persons with stroke .
Reliability of the Canadian Occupational Performance Measure in patients with ankylosing spondylitis.
OBJECTIVE The Canadian Occupational Performance Measure ( COPM ) is a client-centered measure , design ed to detect changes in occupational performance over time . The main aim of our study was to examine the test-retest reliability of the Norwegian version of the COPM in patients with ankylosing spondylitis ( AS ) in 3 different retest modes of data collection . METHODS A total of 119 patients with AS completed the baseline COPM interview before r and omization into one of 3 modes of retest data collection performed 2 weeks later : by personal interview , telephone interview , or mailed question naire . Scores were computed for Performance and Satisfaction , and the 2 sets of scores were examined for reliability by intraclass correlations ( ICC ) , and by the Bl and -Altman procedure for calculation of smallest detectable difference ( SDD ) . RESULTS The ICC coefficients for Performance and Satisfaction were as follows : 0.92 and 0.93 ( rescoring by personal interview ) , 0.73 and 0.73 ( rescoring by telephone interview ) , and 0.90 and 0.90 ( rescoring by mail ) . SDD for the Performance and Satisfaction scores were 1.47 and 1.80 , respectively , for rescoring by personal interview ; 3.14 and 4.00 for rescoring by telephone interview ; and 2.20 and 2.41 for rescoring by mailed survey . CONCLUSION The results confirm that the COPM is a reliable instrument for use in clinical practice in patients with AS , and may serve as an instrument to promote a patient-centered approach in the planning and evaluation of rehabilitation programs . Mailed question naires may replace personal interview in followup examinations , while rescoring by telephone interview is less reliable
