Racial Disparities in the Expression of Paranoia

Sponsor: Indiana University

View on ClinicalTrials.gov

Summary

Paranoia is a pattern of thinking in which people feel suspicious or believe others may want to harm them. It can occur in many people, not only those with a mental health diagnosis, and it can affect daily life, relationships, and overall well-being. Research has consistently shown that Black Americans report higher levels of paranoia than White Americans, even when they do not have a clinical diagnosis. However, the reasons for this difference are not well understood. The goal of this study is to better understand why these differences exist. In the experimental part of the study, researchers will use a randomized design to test whether exposure to stressful experiences related to race leads to higher levels of paranoia among Black American participants. The study will also examine factors that may strengthen or weaken this effect, such as individual experiences and personal characteristics. By identifying how stressful experiences related to race influence paranoia, this research aims to improve how paranoia is measured and understood across different groups. These findings may help researchers and clinicians use more accurate and culturally appropriate tools to assess psychosis-related experiences in diverse populations.

Interventions

BEHAVIORAL

Guided Visual Imagery Task

Participants complete an online, audio-guided visual imagery task designed to experimentally prime social experiences under standardized conditions. After brief instructions to imagine themselves actively participating in each scene, participants complete practice trials with neutral content and then are randomized to listen to one audio-recorded scenario matched to their assigned condition. Each trial includes a brief relaxation period, an instruction period, a guided imagery listening period, and a short recovery period. Scenarios are approximately 30 seconds and are delivered via headphones/speakers within the survey platform. Following the imagery task, participants complete post-task self-report assessments capturing current (state) experiences, including state paranoia and manipulation checks (e.g., imagery vividness and task engagement). The task is administered once in a single session.
