Development and description of PoET

POSITIVE
For the development of PoET, a systematic literature analysis was first carried out within the context of the project “On the Role of Positive Emotions in the Promotion of Mental Health - An Experimental Study” to collect various positive psychology constructs and exercises for the promotion of positive emotion experience. Over a period of three years, these results were discussed in context of the Annual Congress for Psychotherapy in Bochum and a list of about 20 important positive psychological constructs was developed. A further literature analysis of the existing possibilities for promoting these constructs was conducted. Based on their potential regarding feasibility and effects on mental health, eleven constructs were selected by the team and included in the training. Exercises from already existing literature were compiled and own exercises were developed afterwards. After that, the exercises and formal aspects of the training were tested in a pilot phase in January 2022. In the context of this pilot phase, an exemplary training session was conducted with a group of volunteers and feedback was collected as well as integrated into the general PoET concept.The PoET conducted in spring 2022 consisted of two training days of 3.5 h each, one week apart. The training was carried out online via Zoom in groups of about 30 to 35 people and was led by two psychologists who were also part of the research team. A total of eleven lessons on positive psychology constructs were conducted: happiness, hope, optimism, humor, self-efficacy, gratitude, flow, meaningfulness, forgiveness, spirituality, and resilience. At the beginning of each lesson, the participants received a short theoretical input on the respective positive psychology construct. After that, exercises were carried out either in the large group, in groups of three to six people in breakout rooms or alone. Afterwards, there was a short discussion on how the participants experienced each respective exercise. Finally, participants were given at-home-exercises. In addition, the participants received a booklet with descriptions of the exercises and space for notes. During the training days, a PowerPoint presentation was used as visual support. Between the two training days, there was a so-called 7-day challenge which should motivate the participants to complete the exercises at home. Table
