Measures of family stability, sociocultural background, and emotional
ties to parents in medical students (N = 589, mean age = 22 years) pre
dicted their social support measures, assessed 23 to 39 years later (m
ean age = 56 years). Father's education and family's involvement in ch
urch were positively associated with group participation (number of gr
oup memberships), whereas parental loss between the ages of 11 and 20
was negatively associated with group participation: perceived emotiona
l closeness to parents was positively associated with racial closeness
(number of close contacts providing emotional and instrumental suppor
t). Thus, group participation and social closeness were influenced by
distinctly different childhood factors.
