Abstract
Objective
People with advanced cancer experience elevated psychological morbidity and poor quality of life (QoL). The role of third-wave cognitive-behavioural therapy (CBT) interventions in addressing these needs has been examined, but not synthesised in a systematic review. The aim of this review is to systematically identify, analyse and review randomised controlled trials (RCTs) which examined the effect of third-wave CBT interventions on biopsychosocial outcomes (e.g., anxiety, pain, QoL) in this population.
Methods
A systematic search was undertaken on MEDLINE, PsycInfo, CINAHL, Embase and Cochrane CENTRAL. Studies were included if they examined the effect of third-wave CBT interventions on biopsychosocial outcomes in adults living with advanced cancer in RCTs. The Cochrane Risk of Bias tool assessed risk of bias for each study. A random-effects model was fitted to the data and the restricted maximum-likelihood estimator was applied. The standardised mean differences (SMD) between control and experimental groups at short- and long-term follow up were used.
Results
Twelve RCTs with 782 participants were identified. Meta-analyses demonstrated that third-wave CBT interventions were only more effective than comparator groups in the short-term improvement of QoL (SMD = 0.19, 95 % CI [0.00, 0.37], p < 0.05). The results of the 11 other meta-analyses did not reach statistical significance. Eight studies were classified as having unclear risk, and four were classified as high risk of bias.
Conclusions
Third-wave CBT interventions may be effective in enhancing QoL in people with advanced cancer. However, more rigorous RCTs are needed to establish their efficacy in this population.
期刊介绍:
The Journal of Psychosomatic Research is a multidisciplinary research journal covering all aspects of the relationships between psychology and medicine. The scope is broad and ranges from basic human biological and psychological research to evaluations of treatment and services. Papers will normally be concerned with illness or patients rather than studies of healthy populations. Studies concerning special populations, such as the elderly and children and adolescents, are welcome. In addition to peer-reviewed original papers, the journal publishes editorials, reviews, and other papers related to the journal''s aims.
