Such multi-modular programmes (1) may be unnecessarily long for those who do not require a full course of intervention and (2) make it difficult to distinguish those techniques that are effective from those that are redundant. Since dietary restraint is a well-replicated risk and maintaining factor for binge eating, we developed an internet- and app-based intervention composed solely of cognitive-behavioural techniques designed to modify dietary restraint as a mechanism to target binge eating. We tested the efficacy of this combined selective and indicated prevention programme in 403 participants, most of whom were highly symptomatic (90% reported binge eating once per week).<\/jats:p><\/jats:sec><jats:sec id=\"S0033291721002786_sec_a2\" sec-type=\"methods\"><jats:title>Method<\/jats:title><jats:p>Participants were randomly assigned to the internet intervention (<jats:italic>n<\/jats:italic> = 201) or an informational control group (<jats:italic>n<\/jats:italic> = 202).

Secondary outcomes were indices of dietary restraint, shape, weight, and eating concerns, subjective binge eating, disinhibition, and psychological distress.
