Conclusion
depression, anxiety
The main goal of the present study was to test the feasibility of a low-threshold intervention promoting positive emotions. The results showed that PoET in its recent form could be successfully conducted in the general population. In addition, significant effects on depression, anxiety, and optimism were found. Overall, PoET appears to have the potential to contribute to psychotherapeutic interventions. After further and clinical validation, PoET as a low-threshold treatment could be used in the area of prevention as well as during the long waiting periods before the beginning of therapy.
