The last years have seen a paradigm shift concerning addictive disorders, indicating the necessity to study alternative therapeutic models. In this longitudinal study, the objective was to explore the impact of the Change & Grow®
therapeutic model developed and used by VillaRamadas on certain psychological variables that frequently appear associated with addiction. A repeated measures (first and last weeks of treatment) design was used, and the psychological measurements were Beck’s Depression Inventory II (BDI-II), Suicide Ideation Questionnaire (SIQ), State-Trait Anxiety Inventory (STAI), and Montreal Cognitive Assessment (MoCA). Results include 26 (16 male and 10 female) patients. Age varied between 17 and 64 years (M = 35.62, SD = 12.60) and duration of treatment between 91 and 193 days (M = 147.35, SD = 27.05). The MoCA total result was significantly higher in the last week of treatment. The results of BDI-II, SIQ, and STAI (both state and trait) were all significantly lower. Neither duration of treatment nor self-reported motivation presented significant correlation values with the difference between measures for any of the variables. The Change & Grow®
therapeutic model appears to have an impact on relevant psychological variables in patients admitted into treatment for addictive disorders.
