Abstract

Aim To examine the efficacy and acceptability of online, interactive interventions for smoking cessation and to identify treatment effect moderators and mediators. Methods A systematic review and meta‐analysis of the literature (1990–2008) was conducted, finding 11 relevant randomized controlled trials. Data were extracted and risk ratios and risk differences estimated with a random effects model. Results There was no evidence of publication bias. Included trials were of variable methodological quality. Web‐based, tailored, interactive smoking cessation interventions were effective compared with untailored booklet or e‐mail interventions [rate ratio (RR) 1.8; 95% confidence interval (CI) 1.4–2.3] increasing 6‐month abstinence by 17% (95% CI 12–21%). No overall effect of interactive compared with static web‐based interventions was detected but there was significant heterogeneity, with one study obtaining a clear effect and another failing to find one. Few moderating or mediating factors were evaluated in studies and those that were had little effect. Pooled results suggest that only interventions aimed at smokers motivated to quit were effective (RR 1.3, 95% CI 1.0–1.7). Fully automated interventions increased smoking cessation rates (RR 1.4, 95% CI 1.0–2.0), but evidence was less clear‐cut for non‐automated interventions. Overall, the web‐based interventions evaluated were considered to be acceptable and user satisfaction was generally high. Conclusion Interactive, web‐based interventions for smoking cessation can be effective in aiding cessation. More research is needed to evaluate the relative efficacy of interactive web‐based interventions compared with static websites.

  • Systematic reviews and meta-analyses of Web-based interventions for specific behaviors including smoking cessation, reducing alcohol consumption, safer sexual behaviors, and increasing physical activity have positive findings, even if effect sizes tend to be small.

    “Hence, the positive findings of that numerous systematic reviews and meta-analyses of the effects of Web-based interventions for specific behaviors including smoking cessation [36], reducing alcohol consumption [37], safer sexual behaviors [34], and increasing physical activity [38] are reassuring even if the effect sizes tend to be small.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
