Background: The ADAPT Program have improved activities of daily living (ADL) in women with fibromyalgia. To understand the functioning of the program, it is relevant to evaluate how program theory components are linked to outcomes (mechanisms) and how the randomised controlled trial (RCT) context, influenced delivery and outcomes.
Objective: To evaluate ADAPT in terms of dose, mechanisms of change and contextual factors.
Material/methods: Dose was recorded on the n = 21 participants receiving ADAPT in the IMPROvE trial (NCT01352052). A subsample of n = 16 attended one of three 2-hour focusgroups, evaluating mechanisms of change and contextual factors. Interview questions explored participants' interaction with four program components, i.e. how the 'client-centred approach', 'group-based peer-exchange format', 'teaching-learning strategies' and 'long-term program format' triggered mechanisms facilitating/hindering outcomes. Moreover, how randomisation procedures influenced delivery and outcomes.
Results: Attending a long-term educational peer-exchange program, in which participants experienced met by a health professional that legitimised difficulties, facilitated participants knowledge, insights and motivation for changing habits. With time and support, participants experienced increased acceptance of their situation and began to implement more effective ways to perform ADL tasks.
Conclusions/significance: Results support previous findings of improved ADL ability post-ADAPT and provide initial evidence to support the ADAPT Program theory.
