Construct validity of the G-CPAQ and its mediating role in pain interference and adjustment.
Abstract
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. This study also presents that the choice of predictor variables has contributed to theoretical confusion regarding the impact of pain acceptance on pain-related adjustment. The purpose of this study was: (a) to examine the psychometric properties of both the long (20 items) and short (8 items) versions of the Greek-Chronic Pain Acceptance Questionnaire (G-CPAQ); (b) to examine the utility of a 2-factor solution in predicting psychosocial adjustment to pain using confirmatory factor analysis; and (c) to explore the mediating effects of pain acceptance and cognitive defusion, comprising the "open" response style to pain, between pain interference and pain related outcomes. 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 cogni…

The study's findings on long-term disability and quality of life gains lend support to the theoretical framework of ACT and ACT for pain approach, particularly that symptom changes may not be needed for a person to live a functional and valued life.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
