RASMUS is a systematic, behavior-oriented group training in which the following methods are used: mindfulness exercises, exercises in self-compassion/guided meditations, knowledge transfer by means of a teaching talk/lecture, working out the topics in individual and small group work, group exercises, group discussion and exchange, train coping strategies: somatic, cognitive, and emotional levels, independent reflection on what has been learned, homework, weekly protocols, transfer to everyday life, questionnaires on resilience factors, mindfulness, and self-compassion for self-control, linking the course topics with one another.

The body-oriented yoga classes following the Ashtanga style will run in parallel to the RAMUS resilience group (one-hour, once a week). The yoga instructor will support each participant in the form of verbal and hands-on assistance.

RASMUS stands for "Resilience through mindfulness, self-compassion and self-care" and is a German-language 10-week group resilience program with one training unit per week. The main content of the RASMUS is based on seven resilience factors, i.e. acceptance, optimism, taking responsibility, solution orientation, future orientation, role clarity, and network orientation including the aspects of mindfulness, self-compassion, and self-care.

RASMUS has been tested and certified according to the German Prevention Standard. The Central Prevention Test Center has awarded the seal of approval for the areas of exercise, nutrition, stress management/relaxation, and addictive substance consumption. Accordingly, this training program has been certified as a prevention course that is recognized by the German statutory health insurance companies. Furthermore, RASMUS can and is already offered as a (group) online course.

Stress perception and stress processing modes in the sense of state characteristics will be assessed with the Stress Processing Questionnaire (SVF-ak) (Janke & Erdmann, 1997; Janke et al., 1985; Kühn, 1986). The SVF-ak retrospectively asks about the stress processing methods used during a previous stress phase/period. The short version of this instrument which will be used in this study consists of 42 questions for the assessment of the extent to which the 19 processing strategies of the SVF - supplemented by the subtest helplessness - were used in certain stressful situations. Subjects indicate on a 4-point scale ranging from 0 (in no case) to 3 (for sure/ with certainty), how often the thought formulated in the item "went through their mind in the previous situation".

The German version of the Perceived Stress Scale (PSS-10) by Klein et al. (2016) will be used to measure excessive demands and the perception of stress. Subjects indicate on a 5-point Likert scale ranging from null (never) to four (very often) the extent to which situations in their own lives were unpredictable, uncontrollable, and overwhelming in the past month.

Assessment of present and long-lasting anxiety levels will be carried out with the State-Trait-Anxiety Inventory (STAI) (Spielberger et al., 1970, German version by Laux et al., 1981). This is a widely used 40-items multiple-choice questionnaire assessing two dimensions of anxiety: anxiety as a trait (STAI-T), and anxiety as a transient emotional state (STAI-S). The STAI comprises 20 anxiety-related items rated on a 4-point Likert-scale ranging from 1 (not at all) to 4 (totally). Total scores range from 20 to 80 with higher scores indicating higher anxiety. Both state and trait anxiety will be assessed at baseline. At the other time points (mid, post1, post2) only state anxiety will be assessed.

The degree of engagement, immediate response, and changes in affective state will be monitored before and after the first, fifth, and tenth training unit using the Positive and Negative Affect Schedule (PANAS) (German version by Breyer & Bluemke, 2016). This questionnaire consists of 20 adjectives that describe various feelings and emotions and are rated on a five-point scale from "not at all" to "very much". Ten adjectives each capture the dimensions of positive and negative affect. The result is the sum of the values.
