Abstract

Purpose: Value based action is an important process in the psychological flexibility model and is associated with daily functioning in people with chronic pain, but measures of it are not well-developed. The purpose of the present study was to examine the reliability and validity of a Swedish-language version of the Chronic Pain Values Inventory (CPVI) in a large sample of adults seeking treatment for chronic pain.

Material and methods: A Swedish version of the CPVI was created and administered alongside other measures of psychological flexibility and pain-related functioning in a convenience sample of 232 patients admitted for treatment at [redacted for blinding purposes] between February 2014 and December 2015. Internal consistency of the CPVI was assessed as was its relationship to theoretically related facets from the psychological flexibility model. The utility of values-related processes in explaining variance in pain-related functioning was also examined by correlations and hierarchical regression analyses.

Results: Overall, this Swedish-language version of the CPVI was found to have satisfactory reliability and validity. The CPVI subscales yielded high levels of internal consistency. Evidence of construct validity in relation to other measures from the psychological flexibility model was observed as well as evidence of clinical utility in relation to measures of pain-related functioning.

Discussion: This brief self-report measure of values-based action seems to yield valid data in Swedish adults suffering from chronic pain. Values based processes appear important within evidence-based treatments for chronic pain, especially Acceptance and Commitment Therapy (ACT), and the CPVI may help assess these, particularly in predictor studies of pain-related functioning and analyses of therapeutic change processes or mechanisms.
