Lay-health workers
The LHWs provided counseling and support through home visits during an eight-week intervention period. A total of twelve LHWs were involved in the study, and they consisted of staff members who directly provided support services to multicultural families at the MFSC, meaning that they had frequent contact with multicultural families. Any staff member selected to be a LHW had to have at least one year of experience providing support services to multicultural families.Before the program began, the LHWs participated in two four-hour sessions. The training introduced and educated them about the application’s educational content, the method of use, and the content required for counseling. In addition, a manual containing tips for support and counseling as well as instructions on how to use the mobile application and contents were provided to LHWs for continued use.The LHWs visited participants’ homes during the intervention period and provided counseling in case the participant had any difficulties using the application or had questions about healthcare information concerning their young children. They also introduced the participants to the expert Q&A through which they could ask questions and provided support for them to continue using the mobile application.A total of 12 LHW participated in this study, and the researcher confirmed their activities and kept a journal so that support could be provided as intended. In addition, we kept in close contact with them to continuously manage problems that occurred during support. The content of their activities consisted of program usage guide, explanation and recommendation to use the program, problem identification, and connection to additional services. The LHWs’ activity consisted of approximately thirty minutes of support and counseling during each visit.
