Understanding paranoid thinking in times of ethnic diversity

The aim of this project is to investigate the role of paranoia in the general population, with a particular focus on differences in ethnic minority groups. The up to threefold higher risk of psychotic disorders in minority populations underscores the importance of examining paranoid thinking within these groups. Using the DZPG Digital Panel and a digital assessment battery developed within the project, data (e.g., demographic and ethnic information) will be collected at three measurement time points (baseline, 6 months, and 12 months). Advanced analytical approaches, including machine learning methods, will be employed to identify risk factors for paranoid thinking and to predict individual trajectories, which may help to determine optimal time points for preventive interventions. Based on the findings, the final project phase aims to develop preventive measures designed to reduce the risk of paranoid thinking, particularly in vulnerable individuals. Overall, the project can be assigned to the DZPG research focus areas of Risk and Resilience (Domain I), Innovative and Personalized Interventions (Domain II), and Prevention, Participation, and Recovery (Domain III).
