mental illness
The program, which included a 30-min video-based e-learning program, aimed to help schoolteachers gain basic knowledge about mental illness and children of parents with mental illness, recognize children in need of support, and gain confidence in supporting them. A school-based cluster randomized controlled trial was conducted, and the schools were randomly divided into intervention and control groups. The teachers at these schools signed up for the program and participated individually. The outcome measures for the schoolteachers were evaluated at three time points: baseline (T1), post (T2), and one month later (T3). Along with the Sense of Coping Difficulty subscale (primary outcome measure), the following self-developed outcome measures were used: actual behaviors and attitude toward supporting children, knowledge, and self-assessment of program goals achievement. The Sense of Coping Difficulty subscale results at T3 were compared between the groups. Effectiveness over time was assessed for all the outcome measures. The interaction between baseline and intervention effects on the Sense of Coping Difficulty subscale was analyzed. As a part of the process evaluation, open-ended text responses were analyzed qualitatively.
