My research focus throughout my career has been on understanding and facilitating the psychological adaptation to chronic medical illness and disability. This work has covered several areas: examining psychological adjustment to amputation, heart transplant and stroke; designing and testing coping enhancement and wellness interventions for older medical patients; testing home and classroom cognitive-behavioral treatments for medical patients with co-morbid insomnia; and, most recently, testing brief interventions that can be administered by psychologists in the primary care setting. Clinical interests include clinical health psychology, behavioral sleep medicine, primary care psychology, and clinical geropsychology.
