My research program concerns the role of interpersonal relationships in the attainment and maintenance of well-being and physical health. Drawing on Asch (1952) among others, I believe that to understand the effects of interpersonal relationships, one must look at actual social interactions. That is, positive interactions serve as sources of pleasure and buffers during stressful times, whereas negative interactions represent a potent source of stress that can lead to negative moods and harmful health-related behavior such as excessive alcohol consumption. Thus, social interactions represent important contributors to health. However, the processes by which interpersonal relationships and social interactions exert effects on psychological well-being and physical health are not fully understood.
