Abstract

Aims To quantify the overall effectiveness of computer‐delivered interventions for alcohol and tobacco use.

Methods Meta‐analysis of 42 effect sizes from randomized controlled trials, based on the responses of 10 632 individuals.

Results The weighted average effect size (d) was 0.20, P < 0.001. While lower effect sizes were associated with studies addressing tobacco use (d = 0.14) this may well reflect differences in the types of outcome measure used. Effect sizes did not vary significantly as a function of treatment location, inclusion of entertaining elements, provision of normative feedback, availability of a discussion feature, number of treatment sessions, emphasis on relapse prevention, level of therapist involvement or follow‐up period.

Conclusion Findings of the meta‐analysis suggest that minimal contact computer‐delivered treatments that can be accessed via the internet may represent a cost‐effective means of treating uncomplicated substance use and related problems.
