Abstract
Early childhood is a critical period for overall development and well-being, yet children from low-income and low-resourced families, such as Chinese American immigrant families, often have unmet mental health needs as they face additional barriers like limited English proficiency and health literacy. Cultural and linguistic adaptation is essential for equitable access to resources and care. Despite the need, early childhood mental health among Chinese American families remains significantly understudied. A digital mental health solution may pose greater access and convenience to address the mental health needs of this community. Thus, this study aims to collaboratively develop a web-based app called OurChild, which provides culturally and linguistically adapted early childhood mental health and development resources for Chinese American immigrant families in New York City. Using the Participatory Cultural Adaptation Framework for Implementation Research (PCAFIR), the project involves a multiphased participatory co-design process: 1. understanding community needs through formative research and engagement; 2. building a digital library with evidence-based and culturally tailored content; 3. designing a culturally tailored web-based app using a participatory approach; and 4. refining and validating the design through user testing. Informed by formative data from existing studies and programs; focus groups and interviews with community experts (n = 6) and parents (n = 11); user testing with parents (n = 11), and through an iterative re-design process, the app was designed to be user-friendly, culturally relevant, and evidence-based. This study described the co-design process and highlighted the lessons learned in developing culturally tailored digital health tools to promote digital health equity for underserved communities.
