Self-Care Mobile Application for South Korean Pregnant Women at Work: Development and Usability Study

BACKGROUND: Pregnant women at work often encounter barriers to participating in prenatal education or conducting appropriate self-care practices due to their working conditions. PURPOSE: We aimed at developing a mobile-based intervention application (SPWW) for Korean pregnant women at work and testing its usability and preliminary effects to enhance their self-care practices. PATIENTS AND METHODS: The application was developed and tested with thirty-one pregnant women at work and thirteen women’s healthcare providers. The instruments used in this study were a modified Health Practices in Pregnancy Questionnaire II and a System Usability Scale. Descriptive analyses and t-tests were performed using SPSS 25.0. The participants’ open-ended answers were analyzed using ATLAS. ti 8. RESULTS: We developed the application focusing on four self-care topics: healthy diet, physical activity, sufficient rest, and stress management. After using the application for two weeks, participants’ levels of exercise (p = 0.006), adequate fluid intake (p = 0.002), and limiting daily caffeine intake (p = 0.048) significantly improved. In addition to good usability scores, the suggestions for improvement made by the participants included diversifying the educational materials and adding individually customizable functions to the application. CONCLUSION: The application developed in this study enhanced self-care practices of pregnant women at work and showed adequate levels of usability. We expect the developmental process and details of the application provided in this study to serve as a sample guide for future studies.
