Family functioning, alcohol expectancies and alcohol-related problems in a remote Aboriginal Australian community: a preliminary psychometric validation study

While a large proportion of Aboriginal Australians do not consume alcohol, those who do frequently show severe alcohol problems, and alcohol problems are associated with family conflict and violence. The aims were to examine the internal coherence and reliability of measures of family and alcohol measures for indigenous Australians in remote communities. This study involved 99 indigenous people from a remote North Queensland community. Questions were drawn from established questionnaires and administered verbally. Principle components factor analysis revealed three coherent and reliable measures of family conflict, independence, and cohesion. Expectancies of affective change had sound internal reliability for drinkers, and covaried with alcohol problems in the expected direction. The Alcohol Use Disorders Identification Test had two distinct factors relating to consumption and problems, but quantity/frequency measures may have limited reliability due to the common practice among drinkers of sharing alcohol. These measures should facilitate the detection and initial assessment of alcohol and family problems, and may be useful for evaluating change in future interventions that target family and alcohol problems.
