 Results are promising. The 50 rate of stable abstinence achieved by primary smokers over 6 months with 63 abstinence rates for secondary smokers exceeds benchmark success rates reported in the literature for other, comparably intensive interventions, suggesting that a couple-focused intervention different in concept and format from social-support interventions tested in the past may hold promise for health-compromised smokers. The12-month cessation rates were 40 for primary smokers and 63 for secondary smokers.
