  • What drives psychotherapists' willingness to treat individuals with spinal cord injury? A cross-sectional study from Germany

    Open Access•Katja Oetinger, Anika Tyana Heudier et al.•ARTICLE•Frontiers in Public Health•2026

    Introduction Individuals with spinal cord injury (SCI) have a higher prevalence of mental health problems than the general population but face significant barriers to accessing outpatient psychotherapy. Understanding the factors that influence therapists' willingness to treat this population is critical for improving mental healthcare equity. Methods We conducted a cross-sectional online survey among licensed outpatient psychotherapists in Southe…

  • Bibliometric Properties of Placebo Literature From the Jips Database

    Open Access•Katja Weimer, Cliff Buschhart et al.•ARTICLE•Frontiers in Psychiatry•2022

    Bibliometric analyses of the JIPS database can be used to answer questions to the field, for example, to get an impression of blind spots and future directions. However, keywords used in indexing and publications themselves are often general and suggest that placebo research may still be considered a subspecialty of superordinate fields, particularly since there are no journals dedicated to placebo research itself. We invite interested colleagues…

  • Genetics, shared environment, or individual experience? A cross-sectional study of the health status following Sars-CoV-2 infection in monozygotic and dizygotic twins

    Open Access•Sophia Kristina Rupp, Katja Weimer et al.•ARTICLE•Frontiers in Psychiatry•2022

    Both genetics and individual environment play a role in health status after SARS-CoV-2 infection-mental status could be influenced primarily by genetic make-up, whereas for symptom burden and certain fatigue dimensions, non-shared environment could play a more critical role. Possible individual factors influencing the course of the disease were identified. However, gene-environment interactions may still be a source of differences between twins, …

  • Psychosocial Impact of the Covid-19 Pandemic on Healthcare Workers and Initial Areas of Action for Intervention and Prevention—The egePan/Voice Study

    Open Access•Lucia Jerg‐Bretzke, Maximilian Kempf et al.•ARTICLE•International Journal of…•2021

    Retrospectively, the COVID-19 pandemic led to an increase in stress among healthcare workers. Problem areas have different focuses with regard to different living situations, environmental conditions and professions. In order to lay the best basis for healthy and efficient work, it seems necessary to take measures especially tailored to the needs of different groups of healthcare workers

  • Effects of Expectancy on Cognitive Performance, Mood, and Psychophysiology in Healthy Adolescents and Their Parents in an Experimental Study

    Open Access•Daniel Watolla, Nazar Mazurak et al.•ARTICLE•Frontiers in Psychiatry•2020

    With this experimental paradigm, we could not induce relevant placebo effects in adolescents and parents. This could be due to aspects of the study design such as application form and substance, and that healthy subjects were employed. Nevertheless, we could show that adolescents are more sensitive to psychophysiological reactions related with interventions which could be part of the underlying mechanisms of placebo effects in adolescents

  • Are Individual Learning Experiences More Important Than Heritable Tendencies? A Pilot Twin Study on Placebo Analgesia

    Open Access•Katja Weimer, Elisabeth Hahn et al.•ARTICLE•Frontiers in Psychiatry•2019

    Objective: Predicting who will be a placebo responder is a prerequisite to maximize placebo effects in pain treatment and to minimize them in clinical trials. First evidence exists that genetics could affect placebo effects. However, a classical twin study to estimate the relative contribution of genetic influences compared to common and individual environmental influences in explaining interindividual differences in placebo responsiveness has ye…

  • Long-Term Attitude Change After a Single-Day Manager Training Addressing Mental Health at the Workplace

    Open Access•Elena Schwarz, Birgitta Schiller et al.•ARTICLE•International Journal of…•2019

    Mental health problems have become one of the most common causes of incapacity for work, and engender high costs to society. Especially managerial behavior was found to have a great impact on employees' well-being. In order to support those in leading positions in dealing with their own, as well as their employees', psychological stress factors, we conducted a specific manager training. At the same time, we wanted to find out about the training's…

  • Reduction of Motion Sickness With an Enhanced Placebo Instruction

    Björn Horing, Katja Weimer et al.•ARTICLE•Psychosomatic Medicine•2013

    OBJECTIVE: Expectancy and conditioning are underlying mechanisms of placebo and nocebo responses. In previous studies with motion sickness, we could induce nocebo responses by both methods, but no placebo responses. METHODS: In Experiment 1, 64 volunteers (50% women, mean age = 23.5 years) were evaluated to determine the degree they realized speed changes in nauseogenic rotation. For Experiment 2, 32 volunteers (50% women, mean age = 26.0 years) …
