Evidence-based treatments for adolescents with cannabis use disorders in the Spanish Public Health System

The goal of the present study is to describe the implementation of two Evidence-based treatments (EBT) for adolescent Cannabis Use Disorders (CUD) in the Spanish Public Health System, and its main clinical outcomes. Adolescent Community Reinforcement Approach (A-CRA) and Contingency Management (CM) were chosen as the most efficacious treatment programs for this population. A total of 26 adolescent cannabis users entered the study (91.7% male; age = 16.50) at two outpatient clinical facilities in Spain. A quasi-experimental design was utilized, with one group receiving A-CRA only and the other A-CRA + CM. Implementation of both EBTs resulted feasible, with positive clinical outcomes. Results indicated that A-CRA has positive retention (81.3%) and abstinence rates (68.8%). Results for the group receiving A-CRA + CM were not significantly better than A-CRA in retention (100%) or abstinence (75.5%), although sample is too small to establish firm conclusions. Cannabis-related problems and depressive symptomatology also decreased during treatment. Several limitations prevent us from determining the clinical efficacy of A-CRA in this study. The process of translating EBT's to clinical contexts presented with many difficulties that need to be overcome. Recommendations are made for further attempts to implement EBTs in these contexts.
