Despite the widespread implementation of embedded counseling models in veterinary training programs, limited information is available about veterinary students and house officers who seek help, and researchers have not evaluated the effectiveness of counseling services. This study sought to describe clients’ characteristics, presenting concerns, and mental health histories, in addition to determining if participating in counseling was associated with decreases in psychological distress. The sample included 437 Doctor of Veterinary Medicine (DVM) students and house officers receiving embedded counseling services between August 2016 and March 2024 at a public university in the Midwestern United States. Approximately half were first-year students when they initially accessed services. The most common presenting concerns included stress, anxiety, depression, academic performance, perfectionism, self-esteem/confidence, attention/concentration difficulties, mood instability, sleep difficulties, adjustment, family issues, career concerns, eating/body image concerns, and specific relationship problems. DVM students and house officers reported higher scores on some, but not all, measures of psychological distress prior to participating in counseling, compared with a normative sample of college students seeking counseling at university counseling centers. However, these differences tended to be small in magnitude. Participating in counseling was associated with meaningful improvements in depression, generalized anxiety, social anxiety, academic distress, eating concerns, frustration/anger, family distress, substance use, suicidal ideation, and overall psychological distress. Clients who reported improvements in depression and anxiety also tended to report reductions in academic distress, which underscores the value of embedded counseling services in improving the well-being and academic retention of DVM students and house officers. Implications for outreach, research, and clinical practice are discussed.
