Research Focus
Description of the PRRISM Research Lab:
The Psychosocial Risk & Resilience In Stress & Medicine (PRRISM) Research Lab focuses on a central theme of understanding how to reduce stress, stigma, and social adversity and improve health and well-being. Dr. Williamson and other members of the PRRISM lab study how some psychological and social factors can increase risk for poor health outcomes, whereas others can promote resilience in the face of stressors, including chronic medical diseases such as cancer.
Active lines of research include: 1) understanding and reducing the stigma experienced by adults with lung cancer; 2) testing the experimental effects of self-compassion and mindfulness on outcomes such as distress, shame, and social disconnection; and 3) clarifying the biobehavioral pathways through which stress and stigma confer risk for negative mental and physical health outcomes.
