Measuring exposure to cannabis use and other substance use in remote aboriginal populations in Northern Australia: Evaluation of a 'community epidemiology' approach using proxy respondents

Abstract

We evaluate a method to describe changing substance use patterns in northern Australia's remote Aboriginal communities (Arnhem Land, Northern Territory). Substance use was assessed in random samples in two communities A (n = 194) and B (n = 176). Five Aboriginal health workers made assessments independently of each other in community A.

In community C, 101 people were interviewed and were also assessed by four local health workers working together. Proportional agreements (kappa-κ statistic) among health ..
