Abstract

AbstractBackgroundCurrent studies have revealed that acceptance and commitment therapy (ACT) can alleviate the adverse effects of cancer; however, its effectiveness on the psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer remains unclear.AimsThe aims of this study were to identify the effectiveness of ACT on psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer, and to explore moderators.MethodsPubMed, Embase, Web of Science, CENTRAL, PsycINFO, CINAHL, CNKI, VIP, and Wanfang electronic databases were searched from inception to September 29, 2022. The Cochrane Collaboration's risk‐of‐bias assessment tool II and the Grading of Recommendations Assessment, Development, and Evaluation approach were used to evaluate evidence certainty. The data were analyzed using R Studio. The study protocol was registered with PROSPERO (CRD42022361185).ResultsThe study included 19 relevant studies (1643 patients) published between 2012 and 2022. The pooled results showed that ACT significantly improved psychological flexibility (mean difference [MD] = −4.22, 95% CI [−7.86, −0.58], p = .02) and quality of life (Hedges' g = 0.94, 95% CI [0.59, 1.29], Z = 5.31, p < .01) but did not significantly improve fatigue (Hedges' g = −0.03, 95% CI [−0.24, 0.18], p = .75) or sleep disturbance (Hedges' g = −0.26, 95% CI [−0.82, 0.30], p = .37) in patients with cancer. Additional analyses revealed a 3‐month sustainable effect on psychological flexibility (MD = −4.36, 95% CI [−8.67, −0.05], p < .05), and moderation analysis showed that intervention duration (β = −1.39, p < .01) and age (β = 0.15, p = .04) moderated the effects of ACT on psychological flexibility and sleep disturbance, respectively.Linking Evidence to ActionAcceptance and commitment therapy demonstrates effectiveness for psychological flexibility and quality of life of patients with cancer, but there is a lack of evidence regarding its effects on fatigue and sleep disturbance. In clinical practice, ACT should be designed in more detail and rounded to achieve better results.
