Acceptance and commitment therapy for chronic pain conditions on functioning: A systematic review protocol

To explore the efficacy of acceptance and commitment therapy (ACT) on chronic pain in terms of functioning; and to identify the most promising modes and patterns for implementing ACT.

Systematic review and meta-analysis.

We will include randomized controlled trials which focus on the efficacy of ACT on chronic pain conditions with functioning as the primary outcome. Seven databases have been searched and grey literature will also be systematically searched for. Eligible studies will be screened. The newly revised Cochrane risk of bias tool will be used to assess the quality of the included studies. Data will be extracted, and meta-analyses will be performed within specific condition groups of chronic pain. Meta-regression and subgroup analyses will be employed to identify the efficacious modes and patterns for implementing the therapy. Grading of Recommendations Assessment, Development, and Evaluation approach will be applied to reach a convincing conclusion. The study has been funded since July 2018.

This systematic review aims to explore the efficacy of ACT for chronic pain on functioning based on the latest evidence. The most promising manners will be identified for designing and delivering the therapy. An accurate, transparent, and standardized review process is expected by adhering to the instructions of relevant guidelines.

Chronic pain is prevalent worldwide and reduced functioning is one of the leading consequences. With the anticipated evidence of high level, this research attempts to examine the role of acceptance and commitment therapy, a promising psychological intervention, in the management of chronic pain for improving individual's functioning status. The systematic review may contribute to a more convincing and targeted conclusion compared with the existing studies of its kind.
