Collegiate institutions intend to support the psychological well-being of athletes. Grounded in self-determination and basic psychological needs theories, the satisfaction of autonomy, competence, and relatedness are associated with psychological well-being. The purpose of this quantitative causal-comparative study was to examine what, if any, statistically significant difference exists in the satisfaction of college athletes’ basic psychological need of relatedness based on sport type (coactive or interactive) among the social contextual factors of coaches and teammates in the target population of NCAA and NAIA athletes in the United States. Research questions asked if any differences existed between sport type in the satisfaction of college athletes’ basic psychological need of relatedness based on the social contextual factors of coaches and teammates. The sample included current college athletes in coactive (n = 89) and interactive (n = 218) sports types. Responses to the Basic Psychological Needs Satisfaction Scale were collected in order to measure the satisfaction of relatedness. One version was based on the social contextual factor of coaches, and one was based on the factor of teammates. There was a significant difference between coactive and interactive sports participants’ relatedness satisfaction (p = .009) based on the factor of coaches. There was a significant difference between coactive and interactive sports participants’ relatedness satisfaction (p = .005) based on the factor of teammates. Sports practitioners may use this information as they plan team structures and practices. The satisfaction of autonomy and competence should be considered in future research.
