Can evidence-based behavioral therapies be enhanced by the integration of practices deeply rooted in ancient Eastern religions? How might the cultivation of acceptance and self-compassion, along with encouragement to clarify and affirm personally meaningful values, help to buffer people from contextual stressors, build resilience, improve psychosocial functioning, and enhance quality of life? Are these therapies relevant to, and helpful for, clients with diverse identities? These are the questions students and I consider in the design and execution of our research. Our work also explores how invalidation, experiential avoidance, and disengagement from personally meaningful activities contributes to psychological distress (particularly anxiety and associated depression) and examines whether prevention and intervention programs can target these processes and help people cultivate the skills they need to enhance their well-being and quality of life.
