What this trial studies

Researchers will recruit non-Hispanic Black or African American adults in the United States who are registered on the Prolific platform and randomly assign them to a guided visual imagery task that includes race-related stressful content or a control condition. Participants will complete measures of paranoia and other psychological and demographic questionnaires online. The study will test whether the experimental exposure increases paranoia and examine personal and experiential factors that might strengthen or weaken that effect. Data collection and oversight are managed by Indiana University with NIMH collaboration.

Who should consider this trial

Good fit: Non-Hispanic Black or African American adults (age 18+), English-speaking U.S. residents who are registered participants on the Prolific platform.

Not a fit: People under 18, those who do not self-identify as non-Hispanic Black/African American, non-U.S. residents, non-English speakers, or those not registered on Prolific will not be eligible and are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, the results could identify social and psychological targets to reduce harmful paranoia and improve well‑being for Black Americans.

How similar studies have performed: Numerous cross-sectional studies consistently show higher reported paranoia among Black Americans linked to race-related adversity, but experimental causal tests using tasks like guided visual imagery are limited and this approach is relatively novel.
