Group therapy significantly improves long-term smoking cessation rates compared to self-help materials and brief interventions. Evidence is insufficient to compare group therapy with intensive individual counseling.

Area of Science:

  • Behavioral Science
  • Public Health
  • Addiction Medicine

Background:

  • Group therapy provides a platform for individuals to acquire behavioral techniques for smoking cessation.
  • Mutual support among participants is a key feature of group therapy for smoking cessation.

Purpose of the Study:

  • To evaluate the efficacy of group-delivered behavioral interventions for achieving long-term smoking cessation.
  • To compare the effectiveness of group therapy against various control conditions.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials (RCTs) identified through the Cochrane Tobacco Addiction Group Specialized Register.
  • Inclusion criteria: RCTs comparing group therapy with self-help, individual counseling, or no intervention, with at least six months follow-up.

  • Data extraction included participant characteristics, intervention details, and smoking cessation outcomes; meta-analysis used risk ratios and fixed-effect models.

    • Main Results:

    • Group therapy demonstrated a significant increase in smoking cessation compared to self-help programs (RR 1.88, moderate GRADE quality).
    • A small but significant increase in cessation was observed when group therapy was compared to brief healthcare provider support (RR 1.22, low GRADE quality).
    • Group therapy showed no significant difference in effectiveness compared to individual counseling of similar intensity (RR 0.99).

    Conclusions:

    • Group therapy is more effective for smoking cessation than self-help and less intensive interventions.
    • Insufficient evidence exists to determine if group therapy is more effective or cost-effective than intensive individual counseling.
    • The effectiveness of specific psychological components within group programs, beyond support and skills training, requires further investigation.
