Abstract
Purpose To examine the content validity of the Danish version of the Canadian Occupational Performance Measure (COPM-DK). Materials and Methods This cross-sectional study was performed in a hospital and a community rehabilitation centre. The content validity of the COPM was assessed by relating the clients' prioritized occupational performance issues (OPIs) to the conceptual model of the Canadian Model of Occupational Performance and Engagement (CMOP-E) and the levels of the Taxonomic Code of Occupational Performance (TCOP). Six occupational therapy lecturers participated in classifying the OPIs using the TCOP. Results A total of 112 clients from a regional and community-based rehabilitation participated. The 56% regional participants came from a hospital's hand and knee surgery department. The remaining 44% participants came from a community-based rehabilitation centre with in- and outpatient departments. There were 44% males, with a mean age of 65.2 years. They prioritized 495 OPIs, of which 40% concerned self-care, 32% productivity, and 28% leisure. The prioritized OPIs were divided into a total of 224 different OPIs. There were significant differences in which areas were prioritized in the various population groups. Of the OPIs, 64.3% could be classified into the TCOP levels of occupation and activity, i.e., 1/3 of the OPIs were related to tasks and actions, and thus beyond the scope of the COPM. The interrater agreement of the OPI classification was only fair (kappa 0.3). Conclusion The content validity of the COPM seems to depend on how and with which clients it is administered. Caution must be taken to secure OPIs on the higher levels of the TCOP, while maintaining the clients' right to nominate OPI preferences. Therefore, an introductory course and on-going support are recommendable. Bearing this in mind, the COPM seems useful to identify individual clients' prioritized OPIs in a Danish context.
Highlights
The Canadian Occupational Performance Measure (COPM) is a client-centred assessment meant to help clients identify, prioritize, and evaluate issues in the important occupations they encounter in their lives [1]
For each item (OPI, n = 224), we looked at the maximum number of rater agreeing on a categorization and made a “majority vote” based on a minimum of three rater’s agreements (n = 28/224), since at least three raters needed to agree for a majority
The study showed that Danish clients identified very different occupational performance issues (OPIs) within the three areas of occupational performance and that the OPIs were classified in all the five levels described in the Taxonomic Code of Occupational Performance (TCOP)
Summary
The Canadian Occupational Performance Measure (COPM) is a client-centred assessment meant to help clients identify, prioritize, and evaluate issues in the important occupations they encounter in their lives [1]. Being that the COPM helps clients identify their important occupations, it facilitates a client-centred approach, including partnership and collaboration between the professional and the client in the forthcoming rehabilitation [2,3,4,5]. The COPM is a valued tool at the outset of rehabilitation [9, 10]. The COPM is widely used by occupational therapists (OTs) and other health professionals [11, 12], with a track record of more than 25 years and is available in 36 languages [1]. A substantial amount of research documents its good clinimetric properties, and it works well as an assessment and outcome measure in clinical practice [13,14,15]
