摘要：The Purpose of the study is to determine whether there is a meaningful difference between the self-efficacy and self-efficacy perceptions of the footballers (gender, marital status, age and education level etc.) according to their personal qualities. The sample of the work consists of professional male and female soccer teams in Ankara. A total of 354 athletes from 10 male to 5 female soccer teams participated in the study. 128 female soccer players and 226 male soccer players participated. The majority of the athletes participating in the survey are between the ages of 19-23. ''Group Cohesion Scale'' developed by Hatem Ocel and Orhan Aydın (2006) and '' General Self-Efficacy Scale'' developed by Aysin Yesilay, Ralf Shcwarzer and Matthias Gersusalem (1995) were used in the research. Because of the obtained data did not show normal distribution, the nonparametric tests Mann Whitney U and Kruskal Wallis test statistics were used. According to the findings, "Group Cohesion and Self-Efficacy" perceptions differ significantly according to gender. Male participants (X =2,26) were found to have a higher "Group Cohesion" score than female participants (X = 2,08). It is also seen that male participants (X = 2,14) received "Self-Efficacy" scores higher than female participants (X = 1.96). According to the marital status variable, there was no significant difference in the perception of "Group Cohesion" and "Self-Efficacy". There was a significant difference between "Group Cohesion" scores according to age variable. As a result of the multiple comparison tests, the 15-18 age groups were found to score higher than the age group of 19 and above. According to the educational status variable, there was no significant difference between the scale scores of "Group Cohesion and Self-Efficacy".
