    Background A central element of psychotherapy is the dyadic social interaction between therapist and patient. The intermittent coupling of nonverbal behavioral patterns of both interaction partners is referred to as nonverbal or motion synchrony. Motion synchrony significantly correlates with relevant psychotherapeutic process and outcome measures, such as therapeutic relationship and the probability of patient-side discontinuation. At the same time, the education of patients is crucial for an informed decision about psychotherapeutic treatment. In a simulated virtual educational consultation about psychotherapy, the impact of nonverbal social interaction on therapy-related motivation and expectations will be examined. Methods Educational consultation sessions will be conducted with N = 150 participants from the German population who are interested in psychotherapy. Consultations are performed via video call by either a psychologist or an avatar, i.e. a virtual embodied representation of a person. Video data will be analyzed using Motion Energy Analysis to assess motion synchrony. T-tests and a RM-MANOVA with a within-subject factor “time” (pre- vs. post-measurement) and a between-subject factor “group” (psychologist vs. avatar condition) will be conducted. Findings It is hypothesized that subjects in the psychologist condition compared to those in the avatar condition: 1) experience higher values for therapeutic relationship (both self-rated and objectively by motion synchrony) and 2) report a greater increase in therapy-related motivation and expectation from pre- to post-measurement. Discussion The results of the Motion Energy Analysis of the virtual dyadic interaction will provide important insights into the social mechanisms for modulating motivation and expectation and options for fostering the therapeutic relationship.

    Die Aufklärung und informierte Einwilligung stellen eine rechtliche und ethische Voraussetzung für eine Psychotherapie dar. Wir befragten daher 530 psychotherapeutisch Praktizierende in Deutschland zu ihren Einstellungen und zur praktischen Umsetzung der Aufklärung mit informierter Einwilligung für Psychotherapie. Für die meisten Behandelnden (84%) war das Einholen einer informierten Behandlungseinwilligung alltägliche Routine. Viele Psychotherapeut*innen fühlten sich unsicher, ob sie die rechtlichen (63%) und ethischen Verpflichtungen (52%) zufriedenstellend erfüllen. Vier von fünf Behandelnden (80%) gaben an, Patient*innen auch über mögliche Risiken zu informieren. Viele Befragte (52%) befürchteten allerdings, durch diese Informationen Ängste bei Patient*innen auszulösen. Obwohl die informierte Einwilligung für Psychotherapie in der klinischen Praxis eher die Regel als die Ausnahme zu sein scheint, bleibt die Umsetzungsqualität im Hinblick auf die rechtlichen, ethischen und klinischen Anforderungen fraglich.

    Open-label (honestly prescribed) placebos are an ethical way to evoke placebo effects in patients. As part of a mixed-methods study, we conducted in-depth interviews with eight menopausal women who underwent and benefitted from open-label placebo treatment in a randomized-controlled trial of hot flushes. Data were analyzed using Interpretative Phenomenological Analysis. We found that the women had low expectations about the placebo treatment yet endorsed what they referred to as “hope” and openness to “see what happens”. Recording hot flushes via the symptom diary was viewed as a valuable opportunity for self-examination and appraising outcomes. Receiving relief from the placebo treatment empowered women and enhanced their sense of control and agency. In summary, participants’ initial openness towards placebos, their hopes to get better, monitoring symptoms closely, and taking the initiative to address symptoms were components of a positive open-label placebo experience.

    Objective This study aimed to assess clinicians' attitudes and their current clinical practices regarding informed consent for psychotherapy. Method A convenience sample of N = 530 clinicians in Germany (n = 418 licensed psychotherapists and n = 112 postgraduate psychotherapy trainees) took part in an online survey. Results Most clinicians (84%) reported obtaining informed consent for psychotherapy in their daily routine. However, many psychotherapists felt unsure about satisfactorily fulfilling the legal (63%) and ethical obligations (52%). The two most frequently reported components of information disclosure related to explaining the terms and conditions of psychotherapy (96%) and the psychotherapeutic approach (91%). Providing information about mechanisms of psychotherapy (33%) and the role of expectations (30%) were least practiced. One in five psychotherapists reported not informing clients about potential risks and side effects. A considerable proportion reported concern about inducing anxiety in patients by disclosing information about risks and side effects (52%). Conclusions Although obtaining informed consent for psychotherapy seems to be the rule rather than the exception in clinical practice, the quality of its implementation in terms of legal, ethical and clinical demands remains questionable. Training psychotherapists in providing comprehensive informed consent enables informed decision‐making and might have a positive influence on treatment expectations and outcomes.

    Background Informed consent is a legal and ethical prerequisite for psychotherapy. However, in clinical practice, consistent strategies to obtain informed consent are scarce. Inconsistencies exist regarding the overall validity of informed consent for psychotherapy as well as the disclosure of potential mechanisms and negative effects, the latter posing a moral dilemma between patient autonomy and nonmaleficence. Objective This protocol describes a randomized controlled web-based trial aiming to investigate the efficacy of a one-session optimized informed consent consultation. Methods The optimized informed consent consultation was developed to provide information on the setting, efficacy, mechanisms, and negative effects via expectation management and shared decision-making techniques. A total of 122 participants with an indication for psychotherapy will be recruited. Participants will take part in a baseline assessment, including a structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5) disorders. Eligible participants will be randomly assigned either to a control group receiving an information brochure about psychotherapy as treatment as usual (n=61) or to an intervention group receiving treatment as usual and the optimized informed consent consultation (n=61). Potential treatment effects will be measured after the treatment via interview and patient self-report and at 2 weeks and 3 months follow-up via web-based questionnaires. Treatment expectation is the primary outcome. Secondary outcomes include the capacity to consent, decisional conflict, autonomous treatment motivation, adherence intention, and side-effect expectations. Results This trial received a positive ethics vote by the local ethics committee of the Center for Psychosocial Medicine, University-Medical Center Hamburg-Eppendorf, Hamburg, Germany on April 1, 2021, and was prospectively registered on June 17, 2021. The first participant was enrolled in the study on August 5, 2021. We expect to complete data collection in December 2022. After data analysis within the first quarter of 2023, the results will be submitted for publication in peer-reviewed journals in summer 2023. Conclusions If effective, the optimized informed consent consultation might not only constitute an innovative clinical tool to meet the ethical and legal obligations of informed consent but also strengthen the contributing factors of psychotherapy outcome, while minimizing nocebo effects and fostering shared decision-making.

    Synchronous high-speed measurements of a flexible structure under wind gust load
    (AIP Publishing, 2024-07-16) ;
    Neumann, Torben
    Simultaneously measuring the fluid flow around a flexible structure and the resulting deformations during short-term yet highly dynamic flow events is the focus of this fluid-structure interaction (FSI) study. These scenarios occur when a wind gust impacts a flexible structure, leading to extreme loads and significant deflections. To mimic such gusts, a specifically designed wind gust generator is used within a wind tunnel featuring an open test section. A high-speed particle-image velocimetry system records the flow field, while the digital-image correlation technique captures the structural deformations. That allows to perform synchronized coupled fluid-structure measurements for a \mbox{T-structure} under wind gust load. The time-resolved measurements are repeated up to 104 times, allowing for phase-averaging of both the flow and the structural data, and to examine the convergence of the statistics. A comprehensive analysis of the instantaneous and phase-averaged data reveals that the flow field in the vicinity of the structure undergoes noticeable changes during the gust impact. The recirculation region behind the T-structures perceptibly increases when the gust hits the structure. A maximum deformation of about 10% of its height is observed during the highly dynamic gust event. Given (1) the availability of synchronously recorded data for both the fluid flow and the structure deformation, (2) the simplicity of the structure's geometry, and (3) the moderate Reynolds number of about 4 x 10^4, this case also serves as a well-suited benchmark test case for evaluating simulation methodologies for strongly coupled, highly dynamic FSI problems.

    Weiterbildung im Fokus!

    "Warum nehmen bildungsferne Zielgruppen bzw. weiterbildungsbenachteiligte Personen nur selten oder häufig gar nicht an Weiterbildung teil?“ So lautet die Forschungsfrage einer Hamburger Regionalstudie (Laufzeit Mai 2021 bis März 2024), deren zentralen Erkenntnisse in der Handreichung präsentiert werden. Seit langem ist in der Adressaten-, Zielgruppen- und Teilnehmendenforschung der Erwachsenenbildung/Weiterbildung bekannt, dass längst nicht alle Menschen den gesellschaftlichen Erwartungen des lebenslangen Lernens nachkommen (können). Unterschiede im Teilnahmeverhalten zeigen sich aufgrund von Faktoren wie Bildungsstand, Milieuzugehörigkeit, berufliche Tätigkeit, Geschlecht, Alter und Migrationsgeschichte. Doch die Fokussierung auf soziodemographische Faktoren allein reicht nicht aus, um individuelles Teilnahmeverhalten hinreichend begründen zu können. Weitere strukturelle, organisatorische und subjektive Aspekte sowie deren vielfältigen Verschränkungen können eine nicht zu unterschätzende einschränkende wie auch förderliche Rolle hinsichtlich individueller Entscheidungen für die (Nicht-)Teilnahme an formaler Weiterbildung spielen. Dies zeigen eindrücklich die Ergebnisse dieser regionalen Studie. Die Studie beruht auf einem qualitativ-explorativen, subjektwissenschaftlich orientierten Forschungsdesign. Für eine stärkere Rückbindung in das Praxisfeld der Weiterbildung und Bildungsberatung wurden vorläufige empirische Ergebnisse Betroffenen wie Expertinnen und Experten der Praxis rückgespiegelt und diskutiert. Gemeinsam wurden theoretisch begründete, praxisorientierte Handlungsempfehlungen erarbeitet. Die Handreichung umfasst im ersten Teil einen Überblick zum wissenschaftlichen Kontext der Studie, zu bildungspolitischen Zielsetzungen und zum Stand der Adressaten-, Zielgruppen- und Teilnehmerforschung der Erwachsenenbildung. Teil zwei beinhaltet Darlegungen zum Forschungsvorgehen sowie die Präsentation der zentralen Forschungsergebnisse und -erkenntnisse. Im dritten Teil folgen Ableitungen für die Praxis, die sich auf verschiedene Handlungsbereiche und -arenen der Weiterbildungsarbeit mit benachteiligten Zielgruppen beziehen. Sie beinhalten Vorschläge und Ideen sowie theoriegeleitete Reflexionsbezüge für ein professionelles Handeln auf der Mikro- und Mesoebene.
