Randomization and blinding
mental illness
BLIND
When school-based applications were received by the research office, a random number table was prepared by a person who was unrelated to the implementation process, and independent allocations were made to either the intervention or control group in the order of arrival of the applications. After the school applications were received, the same research descriptions, which were designed for individuals, were sent to both the intervention and control groups. Because of ethical considerations and the need to ensure that the participants understood the purpose of the study, we simply stated, in the research description, that the children of parents with mental illness might face challenges. After the allocation of the schools, data managers were no longer blind.The next time any schoolteacher’s individual application form arrived at the research office, the schoolteacher was assigned to the group to which the school was assigned. The participants were guided to their allocation group after the application, and they were no longer blinded. The web surveys and the video were sent at pre-set times, using a computer research electronic data capture accumulation and management system. The quantitative data analyses were blinded to the analysis.
