A Sportsmanship is a concept defined as the awareness of having the values required by sports and the golden key of sports activities. Family attitude and gender are thought to be among the concepts that affect sportsmanship. In this study, it was aimed to examine sportsmanship behavior with family attitude and gender characteristics. The research group consisted of 300 students randomly selected from the secondary schools in the city center of Antalya in the 2018-2019 education year, with a mean age of 12.48 ± 79. In the research conducted with the screening model, the "Physical Education Course Sportsmanship Behavior Scale (BEDSDÖ)" developed by Koç (2013) and a personal information form were used as data collection tools. In the analysis of the data, frequency, percentage, arithmetic mean and standard deviation were used as descriptive statistics methods for personal information. As the data showed normal distribution, the t-test for paired groups and the Anova test for multiple comparisons was used. According to the findings, it was determined that the sportsmanship behaviors of the students were at a high level. A statistically significant difference was found in favor of female students in the sub-dimensions of displaying appropriate behavior according to gender and avoiding inappropriate behavior and in the total of the scale. While there was no statistically significant difference in the dimension of exhibiting appropriate behavior according to the family attitudes of the students, the scores of the students who showed democratic family attitude were higher than the scores of the children of the families with free attitudes in the dimension of avoiding inappropriate behavior and in the total of the scale. When the sportsmanship behavior scores of secondary school students were examined, it was observed that the scores of the female students were higher than the male students. It is thought that changing family attitudes will improve the sportsmanship behaviors of the society.
