Overweight and obesity are an increasing tendencies worldwide. Disordered Eating Behaviors (DEBs) are feeding dynamics commonly present on them, as in Feeding Disorders (FD). These eating and body conditions are highly correlated with specific psychopathological symtoms, such as anxiety and depression, weight-related shame and stigma, and academic stress. Additionally, electroencephalographic findings suggest that weight- and eating-related conditions may be mediated by neural pathways specific to executive functions, such as selective attention and inhibitory control. Therefore, this cuasi-experimental design, pre- and post- measurement, longitudinal cross-sectional study aims to evaluate the effect of a training on psychological flexibility skills, based on Acceptance and Commitment Therapy (ACT) processes, on psychological, electroencephalographic and body composition measures.

This study is a randomized controlled trial nested in the "Le French Gut" e-cohort aiming to test the efficacy of 4 reminder strategies (emails and/or SMS with standard and/or institutional wording) in increasing participation of inactive volunteers. This trial is led in collaboration between the "Le French Gut" project and SKEZI, a DeepTech start-up which markets the data collection solution (SKEZIA online platform) for the "Le French Gut" project and carries out the InnoPRO program, aimed at generating new knowledge in the field of e-cohorts.

In recent years, nature and forest therapy has increasingly become the focus of medical research. Recent scientific findings indicate overall positive effects of nature and forest therapy on physical and mental health. In Asia and Australia, it has already been implemented as a public health concept of prevention and health promotion. The aim of the project is to replicate the experience gained in Asia over the last three decades on the physical and psychological effects of nature/forest therapy in the context of the German forest and to investigate it further scientifically.

Based on the results of the previously published paper "Positive Emotions Training (PoET) as an online intervention to improve mental health: a feasibility study" (Niemann et al., 2023) the goal of this study was to examine the effects of the "Positive Emotions Training" on mental health in a randomized-controlled study. Furthermore, possible predictors for the efficacy of PoET are to be explored. Hypotheses: 1. It was hypothesized that participants receiving PoET would show a significant increase in positive mental health factors at the second assessment point (T2) at end of the second training day. 2. Furthermore, participants receiving PoET are to be expected to show a significant decrease in depression, anxiety and stress symptoms at T2. 3. It was hypothesized that the changes in mental health factors remain stable up to the last assessment point (T3) three month after the training. 4. Lastly, it was hypothesized that there would be no significant changes in the positive or negative mental health factors in the control group at T2 and T3. 5. The possible predictors of the training's efficacy were not hypothesized, but examined in exploratory investigations. Methods: The final sample was n = 207 with n = 90 in the PoET group and n = 117 in the control. The control group did not receive any intervention in the experimental period, but was offered to participate in a later PoET. The allocation was randomized. Participants in the PoET group completed two online training sessions (3 hours each) via Zoom. Group size was about 25-30 people. The sessions included the following positive psychology constructs: happiness, humour, optimism, loving kindness and gratitude on the first day, and hope, self-efficacy, meaningfulness, forgiveness and resilience on the second day. All participants completed a questionnaire at the beginning of the first training session, at the end of the second one as well as three months after the second session. Participants were given an exercise booklet for all exercises (during the training sessions and at home). The one-week break between the two sessions was advertised as a "7-day-challenge" to improve the motivation in participants to exercise at home. Data was collected pseudonymised via "qualtrics". Data analyses were conducted with RStudio. For the possible effects of PoET on mental health two-factorial repeated measures ANOVAs were conducted. For the exploration of possible predictors for the efficacy of the training, a hierarchical regression was conducted.
