The Development Trends, Theories, and Perspectives on Substance Abuse and Psychiatric Comorbidity (Dual Diagnosis) in Adolescents.

The co-occurrence of mental illness and substance abuse is among the most prevalent mental disorders worldwide. It has become more significant in the United States, Europe, and Hong Kong, and it presents complex issues for both mental health and substance abuse practitioners. This paper explores the historical and conceptual issues on dual diagnosis. In addition, different perspectives on dual diagnosis are crucial for developing public policies and programs to address client needs on the road to recovery. The dominant view on dual diagnosis has been the medical perspective. This paper describes three more perspectives: moralistic, psychosocial risk, and phenomenological. This broader view on dual diagnosis will benefit both policy and service development for this population. [ABSTRACT FROM AUTHOR]
