Moderate to vigorous physical activity can reduce symptoms of mental disorders like major depression, anxiety disorders, insomnia, and ADHD. However, in Germany there are no group therapeutical exercise programs for psychotherapy patients in an outpatient context. The current study aims to examine the effectiveness of a manualized exercise program, named ImPuls, which consists of a supervised and non-supervised endurance training in moderate to vigorous intensity and behaviour change techniques.
The current study aims to examine the efficacy (i.e., symptom reduction, increase of heart rate variability, improvement of sleep quality, increase of intrinsic motivation to engage in physical activity, increase of the level of physical activity) of a three-months manualized group exercise program, named ImPuls. The program contains supervised and non-supervised endurance training combined with behaviour change techniques. The manual was designed for patients with major depression, anxiety disorders, insomnia, and ADHD who are waiting for psychotherapeutic treatment. It is assumed that the program will improve the psychopathological symptoms of the different mental disorders. Heart rate variability, level of exercise, sleep quality, motivation and symptoms are measured by objective measures (physiological measurements, accelerometers) and subjective measures (structured interviews and questionnaires). In a randomized controlled trial, ImPuls will be evaluated (n = 38 intervention group vs. n = 37 control group). For four weeks, small group sessions of three to four people take place three times a week, combining endurance exercise (i.e., running) and behaviour change techniques, supervised by two therapists. The training is based on the actual evidence for effective therapeutic effects on psychopathological symptoms, individually adapted to each patient's fitness level (60-80% of the maximal heart rate) and lasts 30 minutes. In the following eight weeks, participants are encouraged to engage in physical activity independently for two to three times a week. It is assumed that the program will reduce symptoms of the different mental disorders as well as increase the heart rate variability, improve sleep quality, intrinsic motivation to engage in physical activity, and the engagement in physical activity. Safety will be monitored throughout the study.

| Change from Baseline in Symptom-Checklist-90®-Standard at Week 13 and one year after study completion | The Symptom-Checklist-90®-Standard (SCL-90®-S, Franke, 2014) was used to identify participants' impairment of physical and mental symptoms. The SCL-90®-S is a self-report questionnaire which captures the subjectively perceived impairment of a person's physical and mental symptoms on various scales. For this study, the scales of Anxiety, Depression, Phobic anxiety, Uncertainty in social contact and compulsiveness were used. Symptoms are registered on a 5-point Likert-Scale ranging from 0 = "being no manifestation of symptoms" to 4 = "being a very strong manifestation of symptoms". Scores will be transformed into T-values with higher scores indicating increasing abnormality (A T-value ≥ 60 indicates clinical abnormality) | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |

| Change from Baseline in Sleep Questionnaire B - Revised version at Week 13 and one year after study completion | With the self-report questionnaire Sleep Questionnaire B - Revised version (Schlaffragebogen B, SF-B/R; Görtelmeyer, 2011), the sleep behavior and sleep experience of the past two weeks can be described and assessed quantitatively and qualitatively. The questionnaire assesses the following 4 sleep indices: Difficulty to Fall Asleep and Difficulty to Sleep Through (1 = "no difficulties" to 4 = "severe and lasting difficulties"), Premature Awakening (1 = "no premature awakening" to 5 = "being severe and lasting premature awakening") and General Sleep Characterization (1 = "negative characterization" to 5 = "positive characterization"). The four scores (averages) range from 1 to 5 since the most scales follow this five-point format. Higher scores of the first three indices indicate more sleep difficulties whereas higher scores of the last index (General Sleep Characterization) indicate a better characterization. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change from Baseline Score in Global Assessment of Functioning-Scale at Week 13 and one year after study completion | The Global Assessment of Functioning-Scale (GAF-Skala; American Psychiatric Association, 2000) is a scale which is used to record the general functional level on axis V of the DSM-IV. On this scale, only the mental, social or professional functions are assessed. The Global Assessment of Functioning-Skala is used to track the clinical progress of patients. The rating is based on the therapist's evaluation. The patient can be asked optionally if the therapist is not sure about the patient's general function. Global functioning is registered on a scale of 1 to 100, with 1 being the lowest and 100 being the highest score of global functioning. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in Perceived Stress Scale at Week 13 and one year after study completion | The Perceived Stress Scale (PSS; Cohen, Kamarck, & Mermelstein, 1983) is the most widely used instrument to measure perceived stress. The self-assessment scale consists out of 10 items and measures the degree to which a situation is appraised as stressful on a 5-point Likert-Scale ranging from 0 = "never" to 4 = "very often". All items summed up build a total score indicating the level of perceived stress. Individual scores can range from 0 to 40 with higher scores indicating higher perceived stress. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change from Baseline in Heart rate Variability at Week 13 and one year after study completion | The heart rate variability (HRV) is an indicator for chronic stress and is measured by the ECG and activity sensor ekgMove (Movisens GmbH, Karlsruhe, Germany). HRV indices are the RMSSD (the square root of the squared mean of the sum of all differences of successive RR intervals) and the high frequency domain (HF; 0.15 - 0.4 Hz) measured by the ecg- and activity sensor ekgMove (Movisens GmbH, Karlsruhe, Deutschland). HRV indices are the RMSSD (the square root of the squared mean of the sum of all differences of successive RR intervals) and the high frequency domain (HF; 0.15 - 0.4 Hz) | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in German version of the 36-Item Short Form Health Survey at Week 13 and one year after study completion | The 36-Item Short Form Health Survey (SF-36, Morfeld, Kirchberger, & Bullinger, 2011) is a self-report questionnaire which captures the quality of life of patients across eight dimensions of subjective health: Physical functioning, physical role function, physical pain, general health perception, vitality, social functioning, emotional role function and mental well-being. With a single item, the current state of health is also inquired in comparison to last year. For each variable item scores are coded, summed and transformed on to a scale from 0 (worst possible health state) to 100 (best possible health state). | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in the Physical Activity, Exercise, and Sport Questionnaire at Week 13 and one year after study completion | The Physical Activity, Exercise, and Sport Questionnaire (Bewegungs- und Sportaktivitätfragebogen, BSA-F; Fuchs, Klaperski, Gerber, & Seelig, 2015) is a self-report questionnaire which measures physical activities in three areas: activity at work, leisure time activity and exercise activity. Participants are asked to specify whether they are currently performing one or more physical activities regularly and to indicate the frequency (per week) and the duration in minutes (per session) for each activity. Only activities that involve larger groups of skeletal muscles are considered to construct a Physical Activity Index (minutes of physical activity per week). The higher the Physical Activity Index the more the person engages in exercise activities. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Physical activity (objective) | Differences of the physical activity level (moderate to vigorous intensity) using the accelerometer Move II ((Movisens GmbH, Karlsruhe, Germany). | week 9 |
| Change From Baseline in Self Concordance of Sport- and Exercise-related Goals Scale at Week 5 and 13 and one year after study completion | The Self Concordance of Sport- and Exercise-related Goals Scale (SKK-Scale, Seelig & Fuchs, 2006) is a self-report questionnaire which measures how strongly the athletic goal intention matches the person's personal interests and values. Four subscales with three items each indicate the intrinsic, identified, introjected and extrinsic motivation of being physically active. Response format is a 4-point-Likert-scale ranging from 1 = "not true" to 4 = "true". A general index for self-concordance of sport- and exercise-related goals (SKK index) will be formed by summing up the identified and intrinsic means scores and subtracting the introjected and extrinsic mean scores. The lowest possible index value is -10 and the highest is +10. A high positive value indicates a strong self-concordance. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in self-efficacy at Week 5 and 13 and one year after study completion | Three different scopes of exercise-related self-efficacy are assessed (vgl. Göhner, Seelig, & Fuchs, 2009). Each scope is measured by one item on a 6-point Likert-scale ranging from 0 = "I don't feel capable at all" to 5 = "I feel 100 per cent capable". The scores of each item will be combined into one mean value with higher scores indicating a stronger self-efficacy. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in strength of goal intention at Week 5 and 13 and one year after study completion | Strength of goal intention is assessed with one item (vgl. Göhner et al., 2009). Response format is a 6-point Likert-scale ranging from 0 = "I don't have this intention at all" to 5 = "I do have a strong intention". A higher score indicates a stronger goal intention. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in implementation intentions at Week 5 and 13 and one year after study completion | The self-report scale implementation intentions (vgl. Göhner et al., 2009) measures whether the person know which physical activity they plan to perform in the following time. A second activity can be named. If the answer is "yes", the person is asked to note the named activity or activities. Subsequently, participants are asked if they would already know the location and time they would perform it as well as how they would get there, how often and with whom they would perform this activity. Positive answers will be summed up to build a score for implementation intentions (including naming the activity and planning details). A higher score indicates stronger implementation intentions. The score can range from 0 to 12. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in Volitional Intention Shielding at Week 5 and 13 and one year after study completion | The index Volitional Intention Shielding (VIS-index, vgl. Göhner et al., 2009) consists of the subscales "Perceived Barriers" and "Counter Strategies". The subscale Perceived Barriers measures how strongly barriers keep the person from exercising. On a list with 19 possible barriers, the participant can indicate how strongly these barriers (on a 4-point Likert-scale ranging from 1 = "not at all" to 4 = "very much") keep him from exercising. The mean of the 19 scores build the subscale Perceived Barriers. The subscale Counter Strategies indicates possible ways to overcome those barriers. A list presents 15 possible counter strategies. Response format is dichotomous with 1 = "Yes, I use this strategy" and 0 = "No, I don't use this strategy". The subscale Counter Strategies is the mean of the 15 scores. The quotient of the two subscales builds the VIS-index (range 0-1). The higher the VIS-index, the more successful is the intention shielding. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change From Baseline in Physical Activity-related Health Competence Questionnaire at Week 13 and one year after study completion | The Physical Activity-related Health Competence Questionnaire (Sudeck & Pfeifer, 2016) is a self-report questionnaire which certain aspects of physical activity-related health competence on a Likert scale from 1 = "strongly disagree" to 4 = "strongly agree". Sub-competencies are 1) movement Competence (6 items), 2) Control Competence (3 items), and 3) Physical-activity-specific self-regulation competence (4 items). All items will be summed, and the total score indicates the level of physical activity-related health competence. Individual scores can range from 13 to 52 with higher scores indicating higher physical activity-related health competence. | Baseline (week 0), posttreatment assessment (week 13), and follow-up assessment (one year after posttreatment assessment) |
| Change from Baseline in the The Homburg's ADHS Scales for adults at Week 13 | The Homburg's ADHS Scales for adults (Homburger ADHS-Skalen für Erwachsene, HASE; Rösler, Retz-Junginger, Retz, & Stieglitz, 2007) serves for the diagnosis of ADHD in adulthood.The instrument consists of four separate procedures. For the current study, two of them were used: (1) The Wender Utah Rating Scale - German version (WURS-K) is used for retrospective diagnosis of childhood ADHD symptoms. (2) The ADHD self-assessment scale (ADHD-SB) includes the 18 diagnostic criteria of DSM-IV and of the ICD-10 research version. The individual characteristics can be scaled from 0 to 3 with higher scores indicating a higher symptom severity. | Baseline (week 0) and posttreatment assessment (week 13) |
