Objective: To discuss the development and structure of Measurements in the Addictions for Triage and Evaluation (MATE) and to present specifications for its practical use. The MATE was designed for use in routine practice for purposes of service allocation and treatment evaluation.
Conceptual framework: The MATE is based on the biopsychosocial model of the World Health Organization, which comprises the International Classification of Diseases (ICD) and the International Classification of Functioning, Disability, and Health (ICF). In order to make the MATE more uniformly applicable, we adopted ICD-10 and ICF concepts, including the view that contextual factors can serve as facilitators or barriers.
Structure of the instrument: The MATE comprises ten modules: (1) Substance Use; (2) Substance Dependence and Abuse; (3) Craving; (4) Depression, Anxiety, and Stress; (5) Indicators for Psychiatric and Physical Treatment; (6) Personality Disorders; (7) Physical Complaints and Symptoms; (8) Personal and Social Functioning Activities and Participation, Care, Support, and Needs; (9) Environmental Factors Influencing Recovery; and (10) Substance Abuse Treatment History.
Implications for practice: The MATE is a practical tool for assessing patient characteristics in routine practice in substance abuse treatment. It is psychometrically sound, promotes knowledge exchange, and facilitates standardization of treatment allocation and treatment evaluation procedures.
