While the prevalence, correlates and mental health impacts of intimate partner violence are well documented in adolescents and young adults, fewer studies have considered physical dating violence among clinical samples of help-seeking young people. In a sample of 98 young people aged 15-24 years (54% females) referred to a specialist public youth mental health service, we examined the 12-month prevalence of physical violence inflicted by an intimate partner and its relationship with psychiatric disorders and psychosocial functioning. The reported prevalence of dating violence in the 12 months prior to referral was 13%. Physical dating violence reported at referral was associated with poorer psychosocial functioning, substance dependence and comorbid Axis I diagnoses at 6-month follow-up. These findings suggest that youth mental health services are well positioned not only to screen for dating violence but to intervene to ameliorate the mental health consequences of abuse and to prevent further violence.
