Abstract: The aim of this study is to investigate whether clinicians consider women have different needs to men. To identify what specific treatment clinicians provided for women with alcohol and drug problems and ascertain whether various clinician variable, are elated to differences in beliefs and treatment provision.The questionnaire items for this study were included in the National Centre for Treatment Development (Alcohol, Drug & Addiction) New Zealand wide telephone survey of alcohol and drug clinicians. Independent interviewers surveyed 217 clinicians. Clinicians were first asked whether they believed women with alcohol and drug problems have differing treatment needs to men. Clinicians responses were compared with various clinician Socio-demographic characteristics (gender, age, ethnicity, professional group, years working in the alcohol and drug treatment field, work setting, qualifications/courses attended, location, and personal alcohol use).Key findings are that almost a quarter (24%) of the clinicians surveyed did not believe that women have different treatment needs to men. However the majority (76%) of clinicians do believe that women have different treatment needs to men. Furthermore findings from this study suggest that significant differences exist in relation to clinicians' practice in new Zealand in relation to clinician, gender, work setting (Crown Health Enterprise, outpatient and residential), and gender mix of caseload
