Study design
A mobile app-based parenting program for multicultural families with young children was developed and evaluated using the five stages of the ADDIE model: analysis, design, development, implementation, and evaluation (The duration of the intervention was eight weeks for all participants. The experimental group (mH-L) received eight weeks of mobile application use and LHW support. The LHWs’ activity consisted of approximately twenty-five minutes of support and counseling during each visit, and they provided positive reinforcement for participants who were comfortable using the application. The experimental group B (mH) received only the mobile application without LHW support. The control group was observed without either a mobile application or LHW support.Given that marriage immigrant women who move to Korea often use a multicultural family support center near their home, there is a concern that potential interactions at the support centers may affect the study outcome. To address this concern, we used a cluster randomization method to randomly assign centers to the three study groups.
