PURPOSE This study investigated the perceptions and experiences of collegiate student-athletes with mental health concerns who are receiving sport psychology services. METHODS A total of 196 college student-athletes (98 male, 98 female) were recruited for the quantitative phase, while 14 athletes from 7 sports participated in the qualitative phase. This integrated approach sought to provide a comprehensive perspective on the research subject. The quantitative participants answered scales for depression (CES-D), anxiety (GAD-7), social support (NCAA RSSS), and mental help-seeking attitude (MHSAS), and the qualitative participants underwent in-depth interviews using a semistructured questionnaire based on a socioecological model. Quantitative data were examined using confirmatory factor analysis, reliability measures, independent t-test, and one-way analysis of variance via SPSS 28.0 and AMOS 28.0, and qualitative data were inspected through content analysis and expert meetings. RESULTS First, higher levels of depression, anxiety, and perceived social support were reported by female athletes as opposed to male athletes. Second, athletes in individual sports reported higher levels of social support than those in team sports. Third, athletes who planned to undergo future psychological counseling reported higher anxiety, social support, and helping attitudes than those with no plans to do so. Fourth, athletes who slept for more than seven hours reported lower levels of depression and anxiety and higher levels of perceived social support than those who slept for six hours or less. Fifth, freshman athletes reported higher depression levels than sophomore athletes. Sixth, student-athletes with no scholarships had higher anxiety levels than those with partial scholarships, who then reported higher perceived social support than those with full scholarships. Seventh, a lack of accessibility was the primary barrier to psychological service access for student-athletes. Eighth, engagement in interpersonal relationships was identified as a major stressor among student-athletes. CONCLUSIONS Differences in collegiate student-athletes’ mental health status as well as perceptions of and experiences in sport psychology services depend on various factors. These findings may serve as foundational data for improving sport psychology support services for collegiate student-athletes.
