Does extended telephone callback counselling prevent smoking relapse?

Area of Science:

• Public Health
• Behavioral Science

Background:

• Smoking relapse remains a significant public health challenge.
• Effective interventions are needed to support long-term smoking cessation.
• Existing quitline services often focus on initial cravings, potentially neglecting later adaptation challenges.

Purpose of the Study:

• To evaluate the efficacy of extended callback counseling in preventing smoking relapse.
• To compare a proactive, later-stage intervention with standard, early-stage quitline support.
• To assess the impact of tailored support on adapting to a smoke-free lifestyle.

Main Methods:

• A randomized controlled trial involving 1444 smokers/ex-smokers.
• Intervention group received extended counseling (4-6 calls, 1-3 months post-quit).
• Control group received standard counseling (4 calls, first month post-quit).

Main Results:

• No significant difference in continuous abstinence rates at 12 months (27% for both groups).
• Extended counseling participants received an average of 1.7 additional calls.
• The 'tasks of quitting' framework may have improved overall service but not the extended calls' impact.

Conclusions:

• Extended callback counseling, delivered after initial cravings subside, did not improve smoking cessation outcomes.
• Standard quitline services, even when revised, appear as effective as extended support for relapse prevention.
• Further research may explore optimal timing and content for sustained smoking cessation support.
