Well-recognized treatment guidelines recommend use of prompt diagnosis, patient information, and nonpharmacological interventions as first-line treatment for patients with fibromyalgia (FM). These recommendations are available only to a limited degree in Norwegian primary healthcare.

Aims of this thesis were to evaluate existing literature of mindfulness- and acceptance-based interventions for patients with FM, and the effects of a multicomponent rehabilitation programme delivered in primary health care. 

The methods applied to address these aims were a systematic review with meta-analyses and a randomized controlled trial (RCT) to evaluate the effects of a multicomponent rehabilitation programme combining two nonpharmacological treatment modalities for patients with FM.

Further, in an observational exploratory study, we evaluated polysymptomatic distress scale scores using latent class growth analysis to identify groups of patients with different symptom severity trajectories.

The results from the systematic review and meta-analyses showed that mindfulness- and acceptance-based interventions for FM patients were associated with small to moderate uncertain effects. In the RCT, a multicomponent rehabilitation programme, combining prompt diagnosis and patient education with a mindfulness- and acceptance-based group intervention followed by physical activity, was compared to a control group receiving diagnosis and patient education and treatment as usual. However, adding a mindfulness- and acceptance-based intervention followed by physical activity did not show enhanced benefits over treatment as usual for patients with FM.

In the observational exploratory study, the analysis of FM trajectories identified two groups: a group that improved slightly and a group that did not, but the groups did not differ in baseline characteristics.
