Abstract

Objectives: Evidence shows that Acceptance and Commitment Therapy (ACT) is an empirically supported psychological approach for chronic pain (CP) management. Although self-compassion is not explicitly a target of ACT, it seems to be one mechanism of change in ACT for CP. However, research is lacking on the benefits of including explicit self-compassionate exercises in ACT for CP. The current study pilot tested a Compassionate ACT 8-session group program (COMP.ACT; n=9), as well as an ACT-only 8-session group program (ACT; n=7), in a sample of women with CP. Methods: The current study follows a quasi-experimental design, and conducts Reliable and Significant Change analyses comparing pre- to post-intervention scores of self-report measures. Results: No differences were found between conditions at baseline, nor between completers and drop-outs. Although preliminary, results showed COMP.ACT led to greater clinical improvements in depression and anxiety, while ACT led to greater improvements in stress and uncompassionate self-responding. Reliable and Significant Change analysis showed that some participants improved significantly (in psychopathological symptoms, valued living and uncompassionate self-responding) in both conditions, while the majority did not change significantly. Conclusions: More research is needed to conclude whether explicit self-compassion exercises are useful in ACT for CP. Limitations and implications are further discussed. © 2021 Walter de Gruyter GmbH, Berlin/Boston.

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.
