Construct validity of the G-CPAQ and its mediating role in pain interference and adjustment.
The Chronic Pain Acceptance Questionnaire (CPAQ) is a measure of pain acceptance comprised of pain willingness (PW) and activity engagement (AE; McCracken et al., 2004). Concerns about the factorial structure of the CPAQ exist, as it is not yet clear whether PW and AE constitute 2 independent constructs or 1, pain acceptance. Concerns also exist about the internal and predictive validity of test score interpretations of this measure. ⋯ One hundred and sixty chronic pain patients completed a questionnaire packet including pain indexes, pain acceptance, cognitive fusion, avoidance, and emotional distress. Confirmatory factor analyses supported the 2-factor solution, though a general good model fit was achieved only for the short G-CPAQ version. Structural equation modeling showed that PW and AE coupled with cognitive defusion partially mediated the influence of pain interference on pain severity, emotional distress, and avoidance of pain.
