The present paper systematically reviewed and critically appraised three different dimensions of motivational interviewing currently utilized in smoking cessation initiatives: social support, motivation, and tailored interventions. A review of four databases generated 57 primary articles, 17 of which met the inclusion criteria of an intervention study utilizing at least one dimension of motivational interviewing, adults between 18 and 64 years, no comorbidities, and a follow-up period of at least 6 weeks. More than 11,600 participants are represented in this review. The implementation of social support, motivation, and tailored interventions yielded mixed results. Furthermore, threats to validity emerged, including self-report, follow-up period, sample sizes, a priori differences in groups, and web-based and text-based interventions. Further research must ascertain the efficacy of the three dimensions of motivational interviewing indicated by the mixed results reported in terms of statistical significance of cessation rates. More empirically rigorous designs with evaluations based on stringent replicable criteria are needed.
