Individual behavioural counselling for smoking cessation.

Area of Science:

• Public Health
• Behavioral Science
• Clinical Medicine

Background:

• Smoking cessation is a major public health goal.
• Individual counseling by specialists may improve quit rates.
• Evidence on the effectiveness of different counseling intensities is needed.

Purpose of the Study:

• To evaluate the effectiveness of individual counseling for smoking cessation.
• To compare individual counseling against no treatment, brief advice, and self-help materials.
• To assess if more intensive counseling yields better cessation outcomes.

Main Methods:

• Systematic review and meta-analysis of randomized and quasi-randomized trials.
• Inclusion criteria: face-to-face individual counseling, at least six-month follow-up.
• Data extraction and analysis focused on smoking cessation rates, using risk ratios and assessing study quality.

Main Results:

• High-quality evidence shows individual counseling is more effective than minimal interventions (RR 1.57) when pharmacotherapy is absent.
• Moderate-quality evidence indicates a benefit of counseling alongside nicotine replacement therapy (RR 1.24).
• Moderate-quality evidence supports a small benefit for more intensive counseling over brief counseling (RR 1.29).

Conclusions:

• Individually-delivered smoking cessation counseling is a highly effective intervention.
• Counseling provides a moderate additional benefit when combined with pharmacotherapy.
• More intensive counseling interventions show a small, but significant, improvement in cessation rates compared to brief counseling.
