This study presents on the Wellness Advising with Motivational Interviewing (WAMI) intervention, which trained academic advisors to support undergraduates in developing motivation toward seeking mental health services. Across two years, participants (N = 1,177) completed assessments and were assigned or randomized to two treatment conditions (Wellness Advising or Treatment As Usual). Wellness Advising participants with elevated symptom profiles, including those who endorsed non-suicidal self-harm, were eligible for one-on-one appointments. This study analyzes the outcomes for students receiving MI in one-on-one sessions, compared to those in the comparison group with similar symptom profiles, who did not receive one-on-one advising, using repeated-measures ANOVAs.
