Enquiry about childhood sexual abuse (CSA) is not routine practice for mental health practitioners undertaking client assessment. This study audited 100 patient charts to determine rates of enquiry and response by mental practitioners around CSA. Fifty-seven mental health staff also completed a subsequent questionnaire exploring factors that influence practice in regard to sexual abuse. Staff lacked confidence in how to ask and effectively respond to sexual abuse disclosure. Mandatory training focusing on trauma informed care could improve staff confidence and capacity to identify and effectively address not only sexual abuse, but childhood trauma and abuse more generally.
