BackgroundAdolescence is a critical period for mental health development, yet prevalences of mental health problems are high among young people. Enhancing mental health literacy in school settings could be an effective strategy for the promotion of mental well-being and prevention of mental health struggles. One promising approach to achieving this goal involves equipping both students and teachers with accessible multimedia resources—such as YouTube Health videos—to enhance their mental health literacy.
ObjectiveThe study evaluates the effectiveness of a short educational YouTube Health video for promoting mental health literacy in adolescents and teachers.
MethodsTwo independent samples of 352 adolescents and 502 teachers from Germany were recruited from a large panel, representative of the German population with internet access. Participants of each sample were allocated to an experimental group (176 adolescents and 254 teachers) and a control group (176 adolescents and 248 teachers) through randomization. The experimental group watched a YouTube Health video designed to increase mental health literacy, while the control group watched a video similar in style but on a different topic. Before and after watching the publicly available YouTube Health videos, mental health knowledge was assessed as a primary outcome through topic-specific quizzes and a self-report in a web-based survey. In addition, all participants were asked to rate the educational, visual, and overall quality of the YouTube Health videos and their usability in school settings. The primary hypotheses were tested with ANOVAs. The quality and usability items were analyzed descriptively.
ResultsFor the adolescents, there were significant main effects of time (F1,350=46.34, P<.001, η2p=0.117) and group (F1,350=6.05, P=.01, η2p=0.017) and a significant time×group interaction (F1,350=39.15, P<.001, η2p=0.101) on stress-specific knowledge, indicating a higher increase in knowledge in the experimental group than in the control group. Similarly, for teachers, significant main effects of time (F1,500=107.31, P<.001, η2p=0.177) and group (F1,500=58.07, P<.001, η2p=0.104) and a significant time×group interaction (F1,500=82.59, P<.001, η2p=0.142) were found. The same pattern of results was observed for the knowledge self-reports in both the students (time: F1,347=103.65, P<.001, η2p=0.230; group: F1,347=8.59, P=.004, η2p=0.024; time×group interaction: F1,347=29.11, P<.001, η2p=0.077) and teachers (time: F1,500=115.40, P<.001, η2p=0.188; group: F1,500=41.16, P<.001, η2p=0.076; time×group interaction: F1,500=64.24, P<.001, η2p=0.114). Overall, the educational, visual, and overall quality of the videos and their usability in school settings were rated as positive by both adolescents and teachers.
ConclusionsThe study findings demonstrate that short educational YouTube Health videos are effective tools for the promotion of mental health literacy among both students and their teachers. Overall, this evaluation paves the way for a wider implementation of mental health education in schools in order to create a more supportive and informed environment to promote mental well-being.
