Brief summary: Research has shown that treatment expectations play a major role in the course of mental disorders and that positive expectations have a beneficial impact on treatment outcomes. Expectations can develop in different ways and an emerging body of research shows that social learning plays a significant role in this process. To date, most studies have investigated the impact of social learning on treatment expectations in the context of pain relief. Little is known about the impact of social learning in the psychotherapeutic treatment of depression. Therefore, this study investigates whether treatment expectations about depression therapy and treatment effects of a short online intervention can be modulated via social learning, i.e., showing positive treatment testimonials.
