The relationships between dispositional optimism, social support, and
mood and performance symptoms associated with the premenstrum were exa
mined in a sample of 101 adult women. Optimism and satisfaction with o
ne's level of social support were positively correlated. Optimism was
related inversely to mood-related symptoms. even after controlling for
the effects of social support. Optimism did not correlate with premen
strual performance impairment. Social support did not correlate with a
ny premenstrual symptoms. (C) 1997 John Wiley & Sons, Inc.
