Objective: To assess athletic trainers' (ATs) perceptions regarding the importance of athletes' beliefs and athletic department stakeholders in facilitating help-seeking for mental health (MH) care. Participants: 534 ATs within collegiate athletic departments (M[subscript age] = 35.50 years; 64.2% women; 87.3% White). Methods: ATs were asked to indicate the extent to which they believed 10 student-athlete beliefs about MH (e.g. confidence MH treatments work) and 10 stakeholders (e.g. teammate) would facilitate student-athletes' help-seeking for MH care (1, "Strongly Disagree," to 5, "Strongly Agree"). Results: We conducted separate two-way mixed design ANOVAs, one for each set of 10 beliefs and 10 stakeholders; each was significant (p's < 0.002). The ATs perceived confidentiality as the most facilitative belief and viewed ATs as the most facilitative stakeholder. Conclusions: ATs differentiate among student-athletes' beliefs and stakeholders on how facilitative each might be in help-seeking, suggesting pathways for improving MH climate within athletic departments through education and policies.
