Children will be selected to receive the SSL program based on results on psychometrically robust measurements and inclusion/exclusion criteria. Selected children will be randomly assigned to the conditions of the two intervention groups (traditional and multimedia versions of SSL) and the wait-list control (WLC) group.~Parents and children from the three groups will complete the same measures at baseline and post-treatment. They will also complete these measures at 3 months follow-up, 6 months follow-up, and 12 months follow-up.~Researchers will compare the results of pre-test to post-test assessments in children participating in the traditional and multimedia versions of SSL compared to those in a WLC group on anxiety symptoms, depressive symptoms, self-esteem, behavioral problems, hyperactivity/inattention, peer relationship problems, and prosocial behavior.~The investigators will also assess these variables in the intervention group at 3 months, 6 months, and 12 months follow-up.
Super Skills for Life (SSL) is a transdiagnostic cognitive-behavioral protocol developed for children aged 6 to 12 with anxiety and comorbid problems (e.g., depression, low self-esteem, and lack of social skills).~SSL consists of eight sessions targeting common risk factors for internalizing disorders such as cognitive distortions, avoidance, emotional management, low self-esteem, social skills deficits and coping strategies.~The aim of the study is to investigate the comparative effectiveness of SSL in its traditional and multimedia version on internalizing and externalizing symptoms in Spanish children between 8 and 12 years of age.
