There was a favourable intervention effect on AUDIT scores (IRR = 0.93, 95% CI = 0.88; 0.98), but not on the number of consequences (IRR = 0.93, 95% CI = 0.84; 1.03).</p> </sec> <sec id="add13051-sec-0008" sec-type="section"> <title>Conclusions</title> <p>An internet‐based brief intervention directed at harmful alcohol use among young men led to a reduction in self‐reported alcohol consumption and AUDIT scores compared with a no‐intervention control condition (assessment only).</p> </sec> </abstract>
