Aims: A randomized controlled trial was used to evaluate a brief research-based intervention designed to promote drinking
within recommended limits on Fridays and Saturdays among moderate drinkers. Methods: The two-page, leaflet-like intervention
included persuasive communication targeting motivational and volitional antecedents of behaviour as specified by an extended theory
of planned behaviour (TPB) and implementation intention theory. Participants were randomly allocated to a control group (TPB questionnaire
only) or to a group receiving the TPB questionnaire plus leaflet-like intervention. Cognitions and drinking behaviour were
measured immediately before the intervention and at 8-weeks follow-up. The pre-intervention questionnaire was distributed to 573
participants of whom 347 (61%) responded at follow-up. Results: Significantly greater reduction in risky drinking on Fridays was
observed among women (but not men) in the intervention group at 8-weeks follow-up. No other post-intervention differences were
found. Conclusions: A low-cost, readily-produced, written intervention focusing on recommended daily limits reduced risky drinking
amongst women on Fridays. Further work on similar interventions is warranted
