Indigenous Justice Clearinghouse Research Brief 20 examines the effectiveness of measures that aim to reduce non-violent offending by Indigenous people in Australia, New Zealand, Canada and the USA. Drawing on the literature available, the brief identifies examples and principles for program development and delivery that have shown potential to reduce Indigenous non-violent offending. The brief suggests that, in general terms, incorporating Indigenous culture(s) into treatment, combining cultural content with Western treatment approaches, incorporating families and communities into treatment, addressing substance abuse and trauma, and addressing the broader historical and social context in which Indigenous offending occurs, are promising approaches to reducing re-offending.
