Alcohol and drug treatment matrices
Launched in 2013, the matrices are portals to the most important research and guidance for British treatment services and for practitioners, managers, and commissioners. Use them to train staff, for professional development, or just to re-experience the revelations made by the seminal and key studies of the past 50+ years. Familiarity with this research and guidance can be seen as a quality indicator, demonstrating that your staff and service are aware of the evidential foundations of their work.
Each matrix consists of a 5x5 table totalling 25 cells, segmenting treatment in to the major practical divisions relevant to its effectiveness and delivery. Within each cell are the main historical and contemporary research landmarks on these different aspects of treatment, reviews offering a panoramic view, expert guidance based on this research, and an option to explore beyond these dozen or so selected documents.
The matrices were developed for the UK by Drug and Alcohol Findings for the Substance Misuse Skills Consortium to promote the development of drug and alcohol treatment services and the treatment workforce. In 2014 the Society for the Study of Addiction joined the other partners in financially and practically supporting this initiative.

Alcohol Treatment Matrix for brief interventions and treatment of alcohol-related problems including those intended to safeguard the community and reduce crime.

Drug Treatment Matrix for harm reduction and treatment of problems related to the use of illegal drugs, including treatment-based interventions to safeguard the community and reduce crime.
