Though the importance of mental health education has been emphasised, how learning about mental health helps the learners' mental health remains to be evaluated. Accordingly, this study aimed to appraise the mental health effects of online mental health classes in a controlled before-after study with a 1-month follow-up. The Depression, Anxiety and Stress Scale-21 and Depression Stigma Scale were completed by 16 students in a mental health class and 12 in a non-mental health class. While there was no significant difference in depression, anxiety and stress, between groups (type of class) and within groups (assessment points), the levels of stigma were significantly lower in mental health students than non-mental health students at post-semester (p = .004). Findings illustrate temporal effectiveness of mental health classes on stigma; however, continuous education is needed to maintain the effects. Educators in mental health are recommended to design a long-term plan to support learners' mental health.
