This study examined the relationship between coaches' efficacy expecta
tions for their teams, ratings of opponents' ability, perceived contro
l over outcome, perceived importance of success, and basketball perfor
mance. A second pur pose was to identify sources of coaches' team effi
cacy. Four collegiate women's basketball coaches completed questionnai
res prior to 10 basketball games (N = 40). Results indicated that coac
hes' efficacy was significantly correlated with perceived control over
the outcome (the higher their efficacy, the higher their perceived co
ntrol). Regression analysis found that coaches' efficacy was a signifi
cant predictor of making free throws and committing few turnovers and
that perceived opponent ability was a significant predictor of coaches
' efficacy. An inductive content analysis of the sources of coaches' e
fficacy beliefs identified sources of high and low efficacy for coache
s (e.g., previous game performance, practice performance, comparison w
ith opponent).
