Efficacy and cost-effectiveness of a minimal intervention to prevent smoking relapse: dismantling the effects of amount of content versus contact.
Relapse prevention remains a major challenge to smoking cessation efforts. T. H. Brandon, B. N. Collins, L. M. Juliano, and A. B. Lazev (2000) found that a series of 8 empirically based relapse-prevention booklets mailed to ex-smokers over 1 year significantly reduced relapse. This study dismantled 2 components of that intervention: the amount of content (number of booklets) and the frequency of contact. Content and contact were crossed in a 2 X 2 factorial design. The criteria of at least 1 week of abstinence at baseline was met by 431 participants, 75%-85% of whom returned 12-, 18-, and 24-month follow-up questionnaires. Eight booklets produced consistently higher point-prevalence abstinence rates than did a single booklet, but frequency of contact did not affect outcome. Moreover, the high-content interventions were highly cost-effective.
