Substance use disorders (SUD) belong to the most frequent behavioural consequences of childhood abuse and neglect (CAN). Of all patients seeking treatment for SUD, 16.3–60.9% report sexual abuse and 28.6–46.2% report physical abuse during their childhood (Simpson & Miller, 2002). Conversely, a lifetime diagnosis of SUD is found in 14–35% of adult survivors of CAN in community samples and in 30–35% of individuals who seek treatment for the consequences of CAN (Levitt & Cloitre, 2005; Mullen, Martin, Anderson, Romans, & Herbison, 1993).
