Are psychoeducational smoking cessation interventions for coronary heart disease patients effective? Meta-analysis of interventions.

Purpose. This systematic review aimed to assess the effectiveness of psychoeducational smoking cessation interventions for coronary heart disease (CHD) patients; and to examine behaviour change techniques used in interventions and their suitability to change behavioural determinants. Methods. Multiple bibliographic databases and references of retrieved articles were searched for relevant randomized controlled studies. One reviewer extracted and a second reviewer checked data from included trials. Random effects meta-analyses were conducted to estimate pooled relative risks for smoking cessation and mortality outcomes. Behaviour change techniques used and their suitability to change behavioural determinants were evaluated using a framework by Michie, Johnston, Francis, Hardeman, and Eccles. Results. A total of 14 studies were included. Psychoeducational interventions statistically significantly increased point prevalent (RR 1.44, 95% CI, 1.20–1.73) and continuous (RR 1.51, 95% CI, 1.18–1.93) smoking cessation, and statistically nonsignificantly decreased total mortality (RR 0.73, 95% CI, 0.46–1.15). Included studies used a mixture of theories in intervention planning. Despite superficial differences, interventions appear to deploy similar behaviour change techniques, targeted mainly at motivation and goals, beliefs about capacity, knowledge, and skills. Conclusions. Psychoeducational smoking cessation interventions appear effective for patients with CHD. Although questions remain about what characteristics distinguish an effective intervention, analysis indicates similarities between the behaviour change techniques used in such interventions.
