Treating Emotional Disorders in Spanish Children: A Controlled Randomized Trial in a Clinical Setting

Super Skills for Life (SSL) is a CBT-transdiagnostic group intervention currently being translated and validated in multiple countries. In Spanish children, it has shown a positive impact on anxious and depressive symptoms, as well as other variables such as self-concept, prosocial behaviors, or behavioral problems. However, the effectiveness of the program to treat internalizing symptoms in children with a mental disorder in a clinical setting has not been examined so far. The aim of this study was to evaluate the effectiveness of SSL in a Spanish sample of children with a major internalizing disorder. Participants aged 8-12 years (71.6% boys) were randomly allocated to the SSL group (n = 43) or the waiting list control (WLC) group (n = 43). All children and their parents completed a series of measures before the first session and after the last session or at about the same time in the WLC group. The effectiveness of the intervention was assessed using generalized estimating equations. Significant reductions from pretest to posttest across multiple outcomes were found in children who participated in SSL group compared to those in the WLC group, including anxiety symptoms (SCAS, p = .02), anxiety interference (CALIS, p = .002), depressive symptoms (CDI, p = .033) and remission from diagnosis (K-SADS, p < .001). This study provides initial support for SSL as an effective treatment for children with emotional disorders in clinical settings. Future studies are needed to analyze long-term effects and broader benefits of the program in clinical contexts.
