Schizophrenia is a severe mental disorder which is accompanied by an enormous individual and societal burden. Despite established efficacy of cognitive behavioral therapy for psychosis (CBTp), its dissemination into routine mental health care remains poor. National regulations such as the NICE guideline in the United Kingdom (NICE, 2014) recommend that CBTp should be offered to every person with psychotic symptoms, but more than 50% do not receive even a single session of CBTp. In Germany, CBTp is “virtually not represented in the psychotherapy health service” (Klingberg & Wittorf, 2012, p. 916; own translation). Internet-based cognitive behavioral therapy (CBT) in a self-help format helps to narrow the treatment gaps in many mental disorders. This approach has been proven feasible and effective in anxiety and depressive disorders. Recently, Internet-based (self-help) interventions are also deployed via smartphone ‘apps’. The feasibility of Internet-based treatments for people with schizophrenia is documented for Internet-based interventions (e.g., medication management) and also reported for smartphone interventions. However, there is a dearth of empirical studies precluding a conclusive picture. The unique features of this project are 1) the first-time evaluation of a symptom-oriented, CBTp-based self-help treatment for people with psychotic symptoms via Internet and 2) the investigation of the enhancement of Internet-based self-help with smartphone assistance. The project is one of the first that contributes to answering the empirical question whether a dissemination of CBTp-based interventions in a purely Internet-based self-help format is effective. Positive findings of this project would pave the way for an easy-to-access treatment option for patients with psychotic symptoms who currently are often deprived of psychotherapeutic treatment.
