An increasing number of college students are seeking services for mental health issues. Many of these students may be interested in pursuing graduate studies in a health-related discipline, such as psychology, social work, or medicine, to enhance their economic and personal well-being, as well as contribute to the health of others. However, they may experience a quandary in the course of completing their applications in that they may desire to disclose their mental illness as a driving motivation to pursue that field, or out of pride in their resilience in the face of such challenges, or feel obligated to disclose, but are unsure about whether such a disclosure will impact the likelihood of their being admitted to their desired program and discipline. This article reviews the current research literature about disclosure on applications, and especially in personal statements, across disciplines. Overall, while few studies have been conducted in this area, and some of them being quite old, the evidence consistently suggests that disclosing a mental illness on applications is considered by admissions committees, may be viewed unfavorably, and may diminish one's chances of getting admitted, even for strong applicants. The implications of these findings for applicants are discussed, including a call for caution when making a decision about disclosure, as well as implications for admissions' committees when reviewing such applications to avoid bias, and potential legal liability, as well as how they can demonstrate the values of the field in welcoming and embracing such applicants.
