Bisher existieren im deutschsprachigen Raum keine Skalen zur Erfassung der Adh{\"a}renz im Bereich der Akzeptanz- und Commitmenttherapie (ACT). Fragestellung: Ziel war es, Skalen zur Erfassung der Adh{\"a}renz von Therapeut_innen f{\"u}r ACT und der Kognitiven Verhaltenstherapie (KVT) zu entwickeln und deren G{\"u}tekriterien zu {\"u}berpr{\"u}fen. Methode Die Validierung der Adh{\"a}renzskalen basierte auf n=38 ACT- und n=31 KVT-Gruppentherapiesitzungen zur Behandlung von depressiven und gemischten St{\"o}rungsbildern. Die Adh{\"a}renz wurde durch zwei Rater_innen anhand von Audioaufzeichnungen bewertet. Ergebnisse: Sowohl f{\"u}r die ACT-Adh{\"a}renzskala (ICC=.96) als auch f{\"u}r die KVT-Adh{\"a}renzskala (ICC=.98) konnten hohe Interraterreliabilit{\"a}ten erreicht werden. Die konvergente Validit{\"a}t konnte anhand einer negativen Korrelation zwischen den beiden Skalen sichergestellt werden (r=-.95). Schlussfolgerungen Beide Adh{\"a}renzskalen bieten eine erste M{\"o}glichkeit, um manualgetreues Therapeut_innenverhalten in ACT- und KVT-Gruppentherapien f{\"u}r Patient_innen mit gemischten St{\"o}rungsbildern zu erfassen. Zudem geben die Ergebnisse einen Hinweis darauf, dass sich die beiden Methoden voneinander differenzieren lassen.}, language = {de} } @article{HeinzelRappFydrichetal.2017, author = {Heinzel, Stephan and Rapp, Michael Armin and Fydrich, Thomas and Str{\"o}hle, Andreas and Teran, Christina and Kallies, Gunnar and Schwefel, Melanie and Heissel, Andreas}, title = {Neurobiological mechanisms of exercise and psychotherapy in depression}, series = {Clinical Trials}, volume = {15}, journal = {Clinical Trials}, number = {1}, publisher = {Sage Publ.}, address = {London}, issn = {1740-7745}, doi = {10.1177/1740774517729161}, pages = {53 -- 64}, year = {2017}, abstract = {Background/Aims: Even though cognitive behavioral therapy has become a relatively effective treatment for major depressive disorder and cognitive behavioral therapy-related changes of dysfunctional neural activations were shown in recent studies, remission rates still remain at an insufficient level. 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.}, language = {en} } @article{EngelJacobsFydrichetal.2015, author = {Engel, Mareike Carina and Jacobs, Ingo and Fydrich, Thomas and Ziegler, Matthias}, title = {Physical and psychological burden of psychotherapists in training}, series = {Psychotherapeut}, volume = {60}, journal = {Psychotherapeut}, number = {6}, publisher = {Springer}, address = {New York}, issn = {0935-6185}, doi = {10.1007/s00278-015-0055-2}, pages = {536 -- 545}, year = {2015}, abstract = {The demanding working and training conditions of psychotherapists in training (PiA) are discussed more and more frequently from social and research perspectives.

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.

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.}, language = {en} } @article{HeisselPietrekFlungeretal.2018, author = {Heissel, Andreas and Pietrek, Anou F. and Flunger, Barbara and Fydrich, Thomas and Rapp, Michael Armin and Heinzel, Stephan and Vansteenkiste, Maarten}, title = {The Validation of the German Basic Psychological Need Satisfaction and Frustration Scale in the Context of Mental Health}, series = {European Journal of Health Psychology}, volume = {25}, journal = {European Journal of Health Psychology}, number = {4}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {2512-8442}, doi = {10.1027/2512-8442/a000017}, pages = {119 -- 132}, year = {2018}, abstract = {The primary aim of the current study was to examine the unique contribution of psychological need frustration and need satisfaction in the prediction of adults' mental well-being and ill-being in a heterogeneous sample of adults (N = 334; Mage = 43.33, SD = 32.26; 53\% females). 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).}, language = {en} }
