[Social work in medical rehabilitation - Development of an empirically grounded programme theory].

Purpose: Social workers are part of the interprofessional rehabilitation team. However, evidence for the effectiveness and a theoretically compatible description of their work are lacking. The aim of the research project "Sozialarbeiterischer Wirkmechanismen in der medizinischen Rehabilitation (SWIMMER)" was the development of a programme theory of social work in medical rehabilitation.

Methods: In this qualitative research project, we conducted interviews with social workers and leading staff, recorded counselling sessions, and made participant observation in rehabilitation facilities. Sampling and analysis were based on grounded theory.

Results: Data from 42 interviews, 14 counselling sessions and 140 hours of participant observations were analysed. Three core categories of a programme theory regarding practice of social work were developed: (i) work types (e. g., information work and supporting applications), (ii) interaction settings (exchange with rehabilitants, the rehabilitation team and external actors) and (iii) tasks of social services (e. g., development of vocational perspectives or professional/social participation, financial and social security). The consequences of social work practice were differentiated into output (e. g., number of applications submitted or options mentioned for a return to work) and outcome factors (e. g., participation in the society or a perspective on this and the well-being of the rehabilitants). A central characteristic is presented (co-production with the rehabilitants).

Conclusion: The hypotheses of the mechanisms of action are grounded in the data and should be explored in further studies. In addition to being useful for practitioners, the model is also suitable for classifying the results of scientific studies.
