The purpose of this study was to examine the relationship between skill performance, mental preparation and collective efficacy in football players. The statistical sample of the study included 80 male soccer players selected randomly from Arak city football teams. Data were collected using the following skill tests: preserving the ball in the air, dribbling test, run sweep with the ball and targeting test, the Ottawa mental skills questionnaire and collective efficacy questionnaire in sports. Then data were analyzed by SPSS 16 software using the statistical tests of Pearson correlation coefficient and simple linear regression. The results of the study showed that there was a significant positive relation between skill performance, mental preparation and collective efficacy. Collective efficacy was also positively correlated with the age, championship background, sports background and team membership history. Moreover, results showed that both predictive variables including skill performance and mental preparation are appropriate predictors of collective efficacy.
