Chan and Lee (1997):<br />
Content - 9 member panel expert review found COPM inadequate in assessing occupational performance<br />
or performance components, but adequate in reflecting client's problems in occupational performance –<br />
interview processes critical, yet not standardized<br />
Criterion related evidence –<br />
<br />
<br />
<br />
<br />
<br />
convergent validity not found between COPM-performance subscale and the Klein-Bell ADL<br />
(KBADL) (some correlations virtually zero or negative)<br />
no convergent or discriminant validity between COPM and Functional Independence Measure<br />
(FIM)<br />
there was convergent validity between COPM-performance subscale and FIM motor subscale, as<br />
well as discriminant validity between FIM cognitive subscale and COPM performance.<br />
There was no convergent validity observed between the initial assessment of COPM satisfaction<br />
subscale and the Satisfaction with Performance Scale Questionnaire (SPSQ); there was a stronger<br />
relationship in the pre-discharge assessment<br />
significant and positive relationship between both subscales of COPM and Social/<strong>Community</strong><br />
subscale of SPSQ; however there was no differentiated convergent, discriminant validity between<br />
them or between COPM and Home Management subscale<br />
Chan and Lee feel that research should be directed to improving the instrument, that currently it is good at<br />
reflecting client's problems in occupational performance (and according to McColl et al 2000 may bring<br />
out a wider variety than simply asking client), but less desirable in facilitating therapists to make<br />
meaningful clinical decisions when client's performance is dependent on competence in performance<br />
components<br />
McColl et al (2000) –<br />
Construct validity:<br />
<br />
<br />
<br />
COPM performance subscale not significantly correlated to any of the three other scales (SPSQ,<br />
the Reintegration to Normal Living Index (RNL) or Life Satisfaction scale (LSS)<br />
Significant but low correlation between COPM -satisfaction and SPSQ, RNL, LSS<br />
Significant and high correlation between COPM Satisfaction and Performance subscales
