Ec. Chang et al., OPTIMISM AND PESSIMISM AS PARTIALLY INDEPENDENT CONSTRUCTS - RELATIONSHIP TO POSITIVE AND NEGATIVE AFFECTIVITY AND PSYCHOLOGICAL WELL-BEING, Personality and individual differences, 23(3), 1997, pp. 433-440
Using weighted least-squares confirmatory factor analysis, support was
found for the bi-dimensionality of optimism and pessimism defined as
positive and negative outcome expectancies, thus, replicating previous
findings (Chang, D'Zurilla & Maydeu-Olivares, 1994; Marshall et al.,
1992). In addition, support was also found for the discriminant validi
ty and utility of employing separate measures of optimism and pessimis
m for predicting individual differences in measures of life satisfacti
on and depressive symptoms. Moreover, significant predictive relations
with these criterion measures were found even after controlling for t
he influence of positive and negative affectivity. Implications regard
ing the present findings for future research on optimism and pessimism
are discussed. (C) 1997 Elsevier Science Ltd.
