Outcome measures
The outcomes were measured at the individual level. The questionnaire was developed by multidisciplinary experts who were research members of this project. The pre-test was conducted among 18 elementary schoolteachers. After watching the video of the program, they were asked to answer the questionnaire and also asked to indicate any points where they had found it difficult to understand sentences or words. Consequently, a few points were raised by the schoolteachers, and some of the wording was corrected.
