Individual recovery expectations and prognosis of outcomes in non-specific low back pain: Prognostic factor exemplar review

This is the protocol for a review and there is no abstract. The objectives are as follows: The primary objective in this review is to synthesize available evidence on the association between individual recovery expectations (including general outcome expectations, treatment expectations, and self-efficacy expectations) and disability outcomes in adults with acute, subacute or chronic non-specific low back pain (LBP). We will explore sources of heterogeneity to identify the impact of differences in participants, measurement of expectations, outcome, follow-up length and study design. We will use internationally-accepted standards for systematic reviews while taking advantage of the opportunity to test methods of two important steps of prognostic reviews, the literature search, and 'Risk of bias' assessment, to inform future syntheses.
