The Bio-pyscho-social model considers that a person’s drug use is shaped by range of interrelated factors that are biological, psychological/emotional and social or structural factors. Recently, there has also been an emphasis on tying in developmental and socio-cultural factors.

This multidimensional and holistic model is capable of underpinning a wide range of practice frameworks and approaches that focus on identifying and responding to the determinants of drug problems and crafting customised solutions for individuals, groups and communities.

The bio-psycho-social model and the commensurate public health model are the most common perspectives evident in the sphere of contemporary AOD service provision in Australia.
