Main Research Projects
Efficacy of psychological interventions
We conduct research on the efficacy of psychological interventions for individuals with anxiety and related disorders, particularly post-traumatic stress disorder, and depression. Currently, we are involved in the following two multicenter trials.
ReCAP: Culturally Adapted Psychotherapy for Refugees
funded by the Federal Ministry of Education and Research (BMBF)
This multicenter trial evaluates the efficacy and cost-effectiveness of three novel and culturally adapted psychological interventions for asylum seekers and refugees in Germany. The clinical trials are carried out at the universities of Frankfurt (Prof. Ulrich Stangier & Dr. Regina Steil), Marburg (Dr. Cornelia Weise & Dr. Dr. Ricarda Nater-Mewes), Munich (Prof. Thomas Ehring) and Münster. In three randomized controlled trials, a short psychoeducation intervention, a transdiagnostic group intervention (CA-CBT+) and individual Imagery Rescripting are being investigated.
This international multicenter randomized clinical trial investigates the efficacy and mechanisms of Imagery Rescripting (ImRs) and EMDR for adult PTSD due to childhood sexual and physical traumatic experiences. The trial is being conducted at 14 sites in Australia, Germany and the Netherlands.

Comparison processes in judgment
We investigate the role of comparison processes in judgment. Using observational and experimental research, we examine for example how different types of comparison (e.g., social, temporal, or couterfactual comparisons) influence judgments of well-being and other mental or physical attributes of the self.

Impact of war and migration on mental health and behavior
We investigate mental health outcomes in survivors of mass violence and the efficacy of mental health services for this population.

Systematic reviews and meta-analyses
We conduct systematic reviews and meta-analyses to evaluate the efficacy of treatments for mental disorders as well as the role of cognitive, emotional and social factors in psychopathology.
