Abstract The study aimed to assess the psychometric properties of the Indigenous Risk Impact Screen ( IRIS) as a screening instrument for determining ( i) the presence of alcohol and drug and mental health risk in Indigenous adult Australians and ( ii) the cut- off scores that discriminate most effectively between the presence and absence of risk. A cross- sectional survey was used in clinical and nonclinical Indigenous and non-Indigenous services across Queensland Australia. A total of 175 Aboriginal and Torres Strait Islander people from urban, rural, regional and remote locations in Queensland took part in the study. Measures included the Indigenous Risk Impact Screen ( IRIS), the Severity of Dependence Scale (SDS), the Alcohol Use Disorders Identification Test ( AUDIT) and the Leeds Dependence Questionnaire (LDQ). Additional Mental Health measures included the Depression Anxiety and Stress Scale ( DASS- 21) and the Self- Report Questionnaire ( SRQ). Principle axis factoring analysis of the IRIS revealed two factors corresponding with ( i) alcohol and drug and ( ii) mental health. The IRIS alcohol and drug and mental health subscales demonstrated good convergent validity with other well- established screening instruments and both subscales showed high internal consistency. A receiver operating characteristics ( ROC) curve analysis was used to generate cut- offs for the two subscales and t- tests validated the utility of these cut- offs for determining risky levels of drinking. The study validated statistically the utility of the IRIS as a screen for alcohol and drug and mental health risk. The instrument is therefore recommended as a brief screening instrument for Aboriginal and Torres Strait Islander people.
