Maintaining and improving labour force participation of older individuals with a chronic disorder deserves attention as the prevalence of chronic disorders is increasing due to ageing of the working population. The aim of this study was to gain insight in differences and similarities in predictors of work participation at higher age (58-65 years) between three different chronic diseases: depression (D), osteoarthritis (O), and cardiovascular disease (C).


A sequential mixed method design was used. The quantitative part was based on the 2002-2003 cohort of the Longitudinal Aging Study Amsterdam. We analysed and compared 3-year predictors of paid work in 256 (response rate at follow-up 95%) participants (55-62 years) between groups with D, O or C using regression analyses. For the qualitative part, in-depth interviews were held with 14 patients with D, O or C, based on purposeful sampling and thematic content analysis. The qualitative findings were integrated with the quantitative findings aiming at complementarity and triangulation.


The quantitative analyses did not show differences in predictors for paid work between D, C and O. Working at baseline, male gender, lower age, having a partner with paid work, and better physical and mental health indicators were predictors of paid work. Self-esteem, functional limitations and work-related characteristics were not predictive for paid work at follow up. The interviews revealed that not work characteristics, but being able to manage your own work and the importance attached to working were predictors for D, C, and O. For D and C work gave purpose in life and social contacts with colleagues, but only for D participation in work was necessary to structure their life.


The results of this mixed method study showed the added value of the interviews to complement quantitative analyses when investigating predictors for participation in workers with D, C and O. Most predictors were similar for the different chronic diseases, but the meaning of predictors for D were different from C and O. In the interviews new predictors came up related to the context and meaning of predictors that were not part of the questionnaires, therewith adding value to the quantitative study. Mixed method designs should be encouraged.
