Emotional disorders in children are often associated with low self-concept and problems with peers, and in many cases externalizing symptoms. Super Skills for Life (SSL) is a transdiagnostic treatment for emotional problems in children that has also shown benefits in other comorbid symptoms. This study aimed to examine, for the first time, the effect of SSL on a clinical sample of Spanish children aged 8-12 years with a major emotional disorder and comorbid externalizing symptoms and low self-concept. A quasi-experimental design with two groups, pretest and posttest, was carried out. Thirty-eight children received the SSL intervention, and 36 children were assigned to a wait-list control (WLC) group. Children in SSL showed statistically fewer posttest emotional symptoms (p < .001), peer problems (p = .002), and overall internalizing and externalizing difficulties (p = .005) compared to children in WLC, in addition to higher posttest self-concept (p = .002). There were no differences in the postinterventional changes between boys and girls in internalizing and externalizing symptoms. However, significant differences were found in some facets of self-concept. The results of this study suggest that the SSL protocol may be useful in Spanish clinical contexts. Still, more research is needed to overcome some of the inherent limitations.
