In this study, in which the correlational research model was used, it was aimed to examine the relationship between the leisure satisfaction and mental well-being levels of special athletes' families. The research group consists of the families of licensed special athletes participating in national and international championships. Accordingly, a total of 255 family members, 78.8% mother (n=201) and 21.2% father (n=54), participated in the study voluntarily. In the scope of the research, "Personal Information Form", "Warwick-Edinburgh Mental Well-Being Scale" and "Leisure Satisfaction Scale" were used as data collection tools to obtain information about the demographic characteristics of families. Descriptive analyzes such as frequency, percentage, mean and standard deviation were used to obtain information about demographic characteristics, and Pearson Correlation analysis was used to determine the relationship between measurement tools. Simple linear regression analysis was used to determine the predictive effect of families' leisure satisfaction levels on their mental well-being. According to the results, it has been determined that there is a positive moderate relationship between the leisure satisfaction and mental well-being levels of special athletes' families, and that leisure satisfaction is a significant predictor of the mental well-being of family members.
