An exploratory analysis of moderating effects in a non-randomized, quasi-experimental evaluation of a college-based mental health literacy curriculum.

Objective: To assess possible moderating variables that influence the effectiveness of a college-based mental health literacy curriculum, Mental Health Awareness and Advocacy (MHAA) . Participants: Students at a Western University in the United States (MHAA treatment group: N  = 474; Comparison group: N  = 575). Methods: Using a non-randomized, quasi-experimental design over six semesters (2017-2019), students in the treatment and control groups reported on key demographic factors, experiences with mental health, and their knowledge, self-efficacy, and behaviors related to mental health literacy in a pretest/post-test format. Linear mixed effects models were used to assess moderation. Results: MHAA curriculum's efficacy varied based on participants' current depression and anxiety levels, whether they had prior personal experience with a mental health concern, whether they had been diagnosed with a mental health concern, and whether they had experienced suicidal thoughts. Conclusions: Reducing anxiety and depression among students may increase the efficacy of the MHAA program.
