Successful Application of a Canadian Mental Health Curriculum Resource by Usual Classroom Teachers in Significantly and Sustainably Improving Student Mental Health Literacy

Objective: To investigate whether the significant and substantive findings from a previous study of youth mental health literacy (MHL) could be replicated using the same methods in another population. Method: We examined the impact of a curriculum resource, the Mental Health and High School Curriculum Guide (The Guide), taught by usual classroom teachers on students' knowledge and attitudes related to mental health and mental illness in Canadian secondary schools. Survey data were collected before, immediately after, and 2 months after implementation of The Guide by teachers in usual classroom teaching. We conducted paired-sample t tests and calculated the Cohen d value to determine outcomes and impact of the curriculum resource application. Results: One hundred fourteen students were matched for analysis of knowledge data and 112 students were matched for analysis of attitude data at pre-intervention, post-intervention, and 2-month follow-up time periods. Following classroom exposure to the curriculum resource, students' knowledge scores increased significantly and substantively, compared with baseline (P < 0.001, d = 1.11), and this was maintained at 2-month follow-up (P < 0.001, d = 0.91). Similar findings for attitude improvement were found (P < 0.001, d = 0.66), and this improvement was maintained at 2-month follow-up (P < 0.001, d = 0.52). Conclusions: These findings corroborate those from a previous study conducted in a different location. Taken together these results suggest a simple but effective approach to improving MHL in young people by embedding a classroom resource, delivered by usual classroom teachers in usual school settings.
