Summary: the goal of this randomized controlled clinical trial is to investigate the efficacy of the internet-delivered intervention empatia on general psychopathology of adolescents with subclinical symptoms compared to a care as usual (cau) control group. the primary objective is to: * investigate the efficacy of the internet-delivered intervention on general psychopathology of adolescents with subclinical symptoms compared to cau. * secondary objectives include: clinician-rated interviews and self-report questionnaires on the level of social and role functioning, time until onset of a mental disorder and service use. furthermore, changes in subclinical symptoms, transdiagnostic mechanisms and therapeutic as well as safety measures are assessed by online self-reports participants will use the internet-delivered intervention empatia during eight weeks. researchers will compare intervention group to a care as usual (cau) group to investigate the efficacy of the internet-delivered intervention empatia on general psychopathology.

the overall objective of this study is to develop and evaluate an internet-delivered indicated prevention program for adolescents with subclinical symptoms designed to target transdiagnostic mechanisms of change. the internet-delivered program will be evaluated in a rct compared to care as usual (cau) including a 1-year follow-up period. the online program empatia aims to strengthen the well-being and mental health of young people in the long term. for example, in this program, young people learn, among other things, how to better deal with worries, stress, low self-confidence, conflicts with other people, or even unpleasant feelings such as anger, fear, or sadness. these are skills that are known to be helpful for the further development of all adolescents and make them more resilient to stress. in this study, the investigators want to investigate whether the program is helpful, how it works, and which adolescents profit most. for the study, 152 adolescents from switzerland are asked to participate in the empatia-program online. in order to study the effectiveness scientifically, all adolescents will be randomly divided into two groups, so the differences can be compared. one group will get access to the empatia-program already at the beginning, the other group after 12 months. the contents of the empatia-program are evidence-based and well-established cognitive-behavioural interventions targeting transdiagnostic mechanisms that have been repeatedly identified to underlie several mental disorders in adolescents: behavioral avoidance, repetitive negative thinking including rumination, worry and intolerance of uncertainty, emotion regulation, self-critical perfectionism and rejection sensitivity. the program consists of 8 modules. it is recommended to complete one module every week with each module lasting about 60 minutes and to make use of additional examples, exercises for everyday life and diaries as often as possible. furthermore, age- and gender specific topics and main testimonials are offered and can be selected by each participant. the intervention allows tailoring contents through topics that can be additionally selected, such as interpersonal conflicts, self-esteem, and social support and additional examples (e.g., if the predominant emotion experienced is anger vs. sadness). information will generally be presented via short video-clips, examples from testimonials, audio files, interactive elements, and cartoons instead of text-based parts. at the end of the modules, there is a short quiz that allows participants to review and solidify what they have learned. participants will be guided (via program integrated chat function) throughout the intervention by e-coaches who are advanced master-students in clinical child and adolescent psychology.
