Do medical patients with a high quantity or quality of social relation
ships have greater chances of recovery and survival than more isolated
individuals? This article reviews longitudinal studies of social rela
tionships and recovery published since the last major reviews of this
field. Reports of 26 such projects were located, primarily in the area
s of heart disease (13 studies) and breast cancer (7 studies). Being m
arried (or socially supported in other ways) was generally associated
with survival or freedom from recurrence in multiyear follow-up studie
s of myocardial infarction (MI) and coronary artery disease patients,
although social support produced negative or mixed results in studies
of short-term physical adaptation after MI or bypass surgery. Studies
relating marital status and other support variables to recurrence and
survival in breast cancer patients also had mixed results. The small n
umber of studies, and other limitations associated with them, suggest
caution in drawing strong conclusions.
