It was hypothesized that leader positive mood would be positively asso
ciated with group performance in a service setting. Additionally, it w
as expected that while leader positive mood would be positively associ
ated with both the leader's level of job satisfaction and job involvem
ent, leader positive mood would be positively associated with group pe
rformance, controlling for both leader job satisfaction and job involv
ement. Leader positive mood also was expected to be positively associa
ted with group performance controlling for group positive affective to
ne. Two potential antecedents of leader positive mood, the leader's le
vel of positive affectivity and the extent to which the leader's own m
anager engaged in contingent reward behavior, were hypothesized to be
positively associated with leader positive mood at work. These hypothe
ses were tested among a sample of 53 sales managers who led groups ran
ging in size from 4 to 9 members. All of the hypotheses were supported
. Implications of these results and directions for future research are
discussed.
