Assessing The Validity Of A Culturally Modified Drinking Motives Questionnaire For Use In Aboriginal Communities.

Abstract

Introduction: Alcohol related harms disproportionately affect Aboriginal people in Australia. Motives to drink have been identified as the most proximal factor to alcohol consumption. Objectives: The aim of this study is to assess the validity of a culturally modified Drinking Motives Questionnaire-Revised (DMQ-R) (Cooper, 1994) with Aboriginal participants. Design: The study was cross sectional, utilising data collected via face-to-face surveys with a sample of adult Aboriginal participants. Participants: A convenience sample of 135 Aboriginal men (n=41) and women (n=94) from the Pilbara Region of Western Australia, who had consumed alcohol in the preceding 12 months. Outcome Measures: The Culturally modified DMQ-R (CDMQ-R) developed in consultation with Aboriginal community researchers and a local Aboriginal Community Reference Group was the primary outcome measure for this study. Results: Confirmatory Factor Analysis indicated the four-factor model of drinking motives as measured by a culturally modified DMQ-R was valid for use with Aboriginal people of the Pilbara region. Conclusions: While most items loaded on the factor solution as hypothesised, there were some minor discrepancies which suggest further modification may be needed. In addition, the reduction of the original five-point scale to a three-point scale created statistical challenges. Future research might seek to further refine the DMQ-R for this population and determine an appropriate method for expanding the response scale incorporating advice from Aboriginal people.
