Bisher existieren im deutschsprachigen Raum keine Skalen zur Erfassung der Adhärenz im Bereich der Akzeptanz- und Commitmenttherapie (ACT). Fragestellung: Ziel war es, Skalen zur Erfassung der Adhärenz von Therapeut_innen für ACT und der Kognitiven Verhaltenstherapie (KVT) zu entwickeln und deren Gütekriterien zu überprüfen. Methode Die Validierung der Adhärenzskalen basierte auf n=38 ACT- und n=31 KVT-Gruppentherapiesitzungen zur Behandlung von depressiven und gemischten Störungsbildern. Die Adhärenz wurde durch zwei Rater_innen anhand von Audioaufzeichnungen bewertet. Ergebnisse: Sowohl für die ACT-Adhärenzskala (ICC=.96) als auch für die KVT-Adhärenzskala (ICC=.98) konnten hohe Interraterreliabilitäten erreicht werden. Die konvergente Validität konnte anhand einer negativen Korrelation zwischen den beiden Skalen sichergestellt werden (r=-.95). Schlussfolgerungen Beide Adhärenzskalen bieten eine erste Möglichkeit, um manualgetreues Therapeut_innenverhalten in ACT- und KVT-Gruppentherapien für Patient_innen mit gemischten Störungsbildern zu erfassen. Zudem geben die Ergebnisse einen Hinweis darauf, dass sich die beiden Methoden voneinander differenzieren lassen. N2 - Background Therapeutic adherence is a central condition for ensuring the validity of psychotherapy studies. To date no German scales to assess adherence in the area of Acceptance and Commitment Therapy (ACT) exist. Objective: The aim was to develop scales to measure the adherence of therapists to ACT and Cognitive Behavioral Therapy (CBT) and to examine their psychometric properties. Methods Validation of the adherence scales was based on n=38 ACT and n=31 CBT group therapies for the treatment of depressive and mixed disorders. Therapists’ adherence was evaluated by two raters using audio recordings. Results Both ACT adherence scale (ICC=.96) and CBT adherence scale (ICC=.98) achieved high interrater-reliabilities. Convergent validity could be ensured by a negative correlation between both scales (r=-.95). Conclusions: Both adherence scales offer a first possibility to measure adherent therapist behavior in ACT and CBT groups for patients with mixed disorders. Moreover, the results indicate that both psychotherapeutic approaches can be differentiated from each other.

Prior to this, validity evidence was provided for the German version of the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) based on Self-Determination Theory (SDT). The results of the validation analyses found the German BPNSFS to be a valid and reliable measurement. Further, structural equation modeling (SEM) showed that both need satisfaction and frustration yielded unique and opposing associations with well-being. Specifically, the dimension of psychological need frustration predicted adults’ ill-being. Future research should examine whether frustration of psychological needs is involved in the onset and maintenance of psychopathology (e.g., major depressive disorder).

However, previous studies which investigated this effect in a single bout of exercise, did not control for confounding peripheral factors that contribute to BDNF-alterations. Therefore, the underlying cause of exercise-induced BDNF-changes remains unclear. The current study aims to investigate serum BDNF (sBDNF)-changes due to a single-bout of graded aerobic exercise in a group of 30 outpatients with MDD, suggesting a more precise analysis method by taking plasma volume shift and number of platelets into account. Results show that exercise-induced increases in sBDNF remain significant (p<.001) when adjusting for plasma volume shift and controlling for number of platelets. The interaction of sBDNF change and number of platelets was also significant (p=.001) indicating larger sBDNF-increase in participants with smaller number of platelets. Thus, findings of this study suggest an involvement of peripheral as well as additional possibly brain-derived mechanisms explaining exercise-related BDNF release in MDD. For future studies in the field of exercise-related BDNF research, the importance of controlling for peripheral parameters is emphasized.

Therefore, the implementation of effective augmentation strategies is needed. In recent meta-analyses, exercise therapy (especially endurance exercise) was reported to be an effective intervention in major depressive disorder. Despite these findings, underlying mechanisms of the antidepressant effect of exercise especially in combination with cognitive behavioral therapy have rarely been studied to date and an investigation of its neural underpinnings is lacking. A better understanding of the psychological and neural mechanisms of exercise and cognitive behavioral therapy would be important for developing optimal treatment strategies in depression. The SPeED study (Sport/Exercise Therapy and Psychotherapyevaluating treatment Effects in Depressive patients) is a randomized controlled trial to investigate underlying physiological, neurobiological, and psychological mechanisms of the augmentation of cognitive behavioral therapy with endurance exercise. It is investigated if a preceding endurance exercise program will enhance the effect of a subsequent cognitive behavioral therapy. Methods: This study will include 105 patients diagnosed with a mild or moderate depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.). The participants are randomized into one of three groups: a high-intensive or a low-intensive endurance exercise group or a waiting list control group. After the exercise program/waiting period, all patients receive an outpatient cognitive behavioral therapy treatment according to a standardized therapy manual. At four measurement points, major depressive disorder symptoms (Beck Depression Inventory, Hamilton Rating Scale for Depression), (neuro)biological measures (neural activations during working memory, monetary incentive delay task, and emotion regulation, as well as cortisol levels and brain-derived neurotrophic factor), neuropsychological test performance, and questionnaires (psychological needs, self-efficacy, and quality of life) are assessed. Results: In this article, we report the design of the SPeED study and refer to important methodological issues such as including both high- and low-intensity endurance exercise groups to allow the investigation of dose-response effects and physiological components of the therapy effects. Conclusion: The main aims of this research project are to study effects of endurance exercise and cognitive behavioral therapy on depressive symptoms and to investigate underlying physiological and neurobiological mechanisms of these effects. Results may provide important implications for the development of effective treatment strategies in major depressive disorder, specifically concerning the augmentation of cognitive behavioral therapy by endurance exercise.

The complementary focus on job and training pressure and its consequences have received little attention so far. The nationwide survey (N = 464) contains information on essential person-related and training-related risk factors and resources. Moreover, the study provides comparisons concerning different professional categories with high psychological and social demands as well as with the training conditions of psychotherapists in 2009. The study shows the difficulties and demanding situation of financing the training. The PiAs showed significantly higher stress levels than other groups of persons and comparably low resilience combined with a high working engagement. Only a few PiAs had a healthy behavioral and perceptional work pattern. The results underline the necessity for an examination of the training and working conditions of PiAs. Accordingly, options for interventions are presented.
