Wg. Graziano et al., COMPETITIVENESS MEDIATES THE LINK BETWEEN PERSONALITY AND GROUP-PERFORMANCE, Journal of personality and social psychology, 73(6), 1997, pp. 1394-1408
The performance of individuals within groups, and of groups as units,
is the product of immediate goal structures and personality difference
s pertinent to those goals among group members. A level-of-analysis ap
proach linked the dimension of agreeableness to situated competitivene
ss and task performance in group settings. Hypotheses were (a) individ
ual differences in self-rated and other-rated competitiveness are rela
ted (inversely) to the Big Five dimension of agreeableness, (b) immedi
ately situated promotive and contrient goal structures influence self-
ratings of competitiveness, (c) immediate goal structures differential
ly activate competitiveness to affect task performance in groups, and
(d) agreeableness effects on task performance are partially mediated b
y competitiveness. Structural equation modeling corroborated hypothese
s about the links among agreeableness, competitiveness, and task perfo
rmance.
