A self-management intervention for people with multiple sclerosis: The development of a programme theory in the field of rehabilitation nursing

Background: People with multiple sclerosis (PwMS) have recurrent stays in rehabilitation clinics because of progressive disease. Nurses are key players in supporting PwMS through self-management interventions. How-ever, little is known about the effectiveness, or sustainability of nursing interventions. The aim of this study was to develop a nurse-led self-management intervention and its programme theory for PwMS in one Swiss reha-bilitation clinic. Methods: On the basis of the Medical Research Council framework, we developed a theory-based programme for a nurse-led intervention. As key element of the intervention, we created a consulting guidance.Results: As part of the programme theory, we created a systematic plan (action model) to illustrate how contextual resources (e.g., skills of the MS nurse and responsibilities of the multidisciplinary team) need to be coordinated. The change model shows how changes in the intervention lead to the achievement of outcomes (e. g., increased self-efficacy). The consulting guidance was refined by PwMS and four Swiss MS experts.Conclusions: An initial programme theory is a solid foundation for the next phases of the theory-based evaluations to refine the programme theory and sustainable implementation of the intervention.
