This systematic review and meta-analysis investigated effective components of group-based smoking cessation programs. Nineteen randomized controlled trials were included, revealing 28 behavior change techniques (BCTs). "Information about health consequences" and "problem-solving" were most frequent. Group-based interventions showed higher 6-month cessation rates (OR = 1.75, 95% CI = 1.12 to 2.72, p < .001). Four BCTs – problem-solving, information about health consequences, information about social and environmental consequences, and reward (outcome) – were significantly associated with increased cessation rates. The study highlights the effectiveness of group-based programs and identifies key BCTs for improving future interventions.
