Can stand‐alone computer‐based interventions reduce alcohol consumption? A systematic review

Abstract

Aim To determine the effects of computer‐based interventions aimed at reducing alcohol consumption in adult populations. Methods The review was undertaken following standard Cochrane and Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidance for systematic reviews. The literature was searched until December 2008, with no restrictions on language. Randomized trials with parallel comparator groups were identified in the form of published and unpublished data. Two authors independently screened abstracts and papers for inclusion. Data extraction and bias assessment was undertaken by one author and checked by a second author. Studies that measured total alcohol consumption and frequency of binge drinking episodes were eligible for inclusion in meta‐analyses. A random‐effects model was used to pool mean differences. Results Twenty‐four studies were included in the review (19 combined in meta‐analyses). The meta‐analyses suggested that computer‐based interventions were more effective than minimally active comparator groups (e.g. assessment‐only) at reducing alcohol consumed per week in student and non‐student populations. However, most studies used the mean to summarize skewed data, which could be misleading in small samples. A sensitivity analysis of those studies that used suitable measures of central tendency found that there was no difference between intervention and minimally active comparator groups in alcohol consumed per week by students. Few studies investigated non‐student populations or compared interventions with active comparator groups. Conclusion Computer‐based interventions may reduce alcohol consumption compared with assessment‐only; the conclusion remains tentative because of methodological weaknesses in the studies. Future research should consider that the distribution of alcohol consumption data is likely to be skewed and that appropriate measures of central tendency are reported.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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.
