In 2015 the National Organisation for the Treatment of Abusers (NOTA) established a prevention sub-committee, chaired by Jon Brown. NOTA has, of course, always been concerned with the prevention of sexual violence and abuse. However the establishment of the prevention sub-committee signals an important new direction for NOTA by expanding its conception of, and involvement in, prevention activities beyond its historical focus on therapeutic and risk management responses with known sexual offenders. My aim in this Editorial is to consider the implications of this development for the Journal, by way of outlining the kinds of research I think are needed to inform an expanded prevention agenda. My suggestions are by no means exhaustive, and I acknowledge that others may have different priorities and emphases.
