Purpose A shift from providing long-term disability benefits to promoting work reintegration of people with remaining work capacity in many countries requires new instruments for work capacity assessments. Recently, a practice-based instrument addressing biopsychosocial aspects of functioning, the Social Medical Work Capacity instrument (SMWC), was developed. Our aim was to examine the content validity of the SMWC using ICF core sets. Methods First, we conducted a systematic search to identify relevant ICF core sets for the working age population. Second the content of these core sets were mapped to assess the relevance and comprehensiveness of the SMWC. Next, we compared the content of the SMWC with the ICF-core sets. Results Two work-related core sets and 31 disease-specific core sets were identified. The SMWC and the two work-related core sets overlap on 47 categories. Compared to the work-related core sets, the Body Functions and Activities and Participation are well represented in the new instrument, while the component Environmental factors is under-represented. Compared to the disease-specific core sets, items related to the social and domestic environmental factors are under-represented, while the SMWC included work-related factors complementary to the ICF. Conclusion The SMWC content seems relevant, but could be more comprehensive for the purpose of individual work capacity assessments. To improve assessing relevant biopsychosocial aspects, it is recommended to extend the instrument by adding personal and environmental (work-and social-related) factors as well as a more tailored use of the SMWC for assessing work capacity of persons with specific diseases or underlying illness.

Purpose: Many high-income countries are witnessing a shift of focus on eligibility for disability benefits towards promotion of work reintegration. However, little is known about how countries assess work capacity, and how a job match is then obtained. The current study aims to compare work capacity assessments and available efforts to achieve a job match in eight high-income OECD countries. Methods: A survey was conducted among key stakeholders concerning organization of work capacity assessments in social security settings, and efforts made to obtain a job, across eight OECD countries: Australia, Denmark, Finland, Iceland, Sweden, the Netherlands, the United Kingdom and the United States. Results: In most countries, work capacity is assessed at several time points, with variations in moments and in information used for job matching. In countries obtaining information on personal and work levels, the search to find a job match usually begins with the persons who have disabilities. Conclusion: Although a shift towards a holistic focus in work capacity assessment has been recognized, medical factors still prevail. Limited emphasis is placed on the implications of functional limitations for the possibilities of work. A holistic approach to assessment needs to be coupled with holistic support measures through provision of coordinated and high quality job matching services. ä IMPLICATIONS FOR REHABILITATION Besides determining eligibility for benefits the outcome of the work capacity assessment can also be used for other purposes such as reintegration and should not result in a static description of work capacity but also deliver insight in support needs. Involving multiple institutions and disciplines in work capacity assessments may result in a broader overview of the claimants' capacities, however this places high demands on cooperation and data sharing of all those involved. Incorporating the claimants own perspective on work capacity and possibilities to work might improve the legitimacy of the process and reasonably also the achievement of a good and sustainable job match. This can be achieved by using self reported questionnaires and interviews in the assessments.
