Developing and Testing a Method for Engagement in Research Using WhatsApp (WI-CARE)

African immigrants are one of the fastest-growing immigrant populations in the United States but remain underrepresented in clinical, public health, and patient-centered research. Barriers to engagement include distrust of research institutions, concerns about privacy and immigration status, language differences, stigma, limited research literacy, and a lack of culturally appropriate engagement approaches. These barriers may limit opportunities for African immigrants to influence the questions, methods, implementation, interpretation, and dissemination of research relevant to their communities.

WhatsApp is widely used by African immigrant communities for communication, information sharing, and social support. Although researchers have used WhatsApp for participant recruitment and data collection, less is known about how the platform can support sustained and meaningful engagement across the research lifecycle. There is also no standard protocol to guide researchers in using WhatsApp for research engagement with African immigrant communities.

This mixed-methods study will develop and pilot the WhatsApp Immigrant-Centered Research Engagement (WI-CARE) protocol. WI-CARE will provide structured guidance for using WhatsApp features to support culturally and linguistically appropriate communication, privacy, trust, inclusion, and participation in research. The study is guided by the Unified Theory of Acceptance and Use of Technology and measures of patient engagement in research.

Aim 1 will identify the WhatsApp features and engagement practices that facilitate or hinder research engagement. Adult African immigrants will complete a survey about their experiences with WhatsApp, preferences for research communication and participation, perceived barriers, trust, privacy, and factors affecting their willingness to use WhatsApp for research engagement. Focus groups will provide additional information about participants' experiences and recommendations.

Aim 2 will use findings from Aim 1 to develop the WI-CARE protocol through a participatory process led by the study team, which includes African immigrant partner organizations and academic researchers. The protocol will address onboarding, informed consent, communication, privacy and confidentiality, multilingual engagement, facilitation, technical support, data collection, interpretation of findings, and dissemination. African immigrant patients and other experts will review the draft protocol for feasibility, usability, cultural relevance, and adaptability. Their feedback will guide iterative revisions.

Aim 3 will pilot WI-CARE among adult African immigrants residing in Connecticut, Maine, Massachusetts, Minnesota, Pennsylvania, and Rhode Island. Approximately 300 participants will be enrolled in a centralized WhatsApp community. Participants will be invited to opt into structured scenarios based on their interests and availability. The scenarios will simulate activities conducted during different stages of research, including onboarding and consent, research planning, recruitment, data collection, interpretation of findings, and dissemination.

Within each scenario, trained facilitators will use the WI-CARE protocol to guide participants through research-related activities. Participants will then evaluate the clarity, accessibility, cultural relevance, privacy, and usability of the engagement process. WhatsApp activity metrics, surveys, and individual interviews will be used to assess participation, retention, task completion, engagement quality, trustworthiness, acceptability, usability, and feasibility. The study will also examine whether engagement experiences differ according to participant characteristics and geographic location.

Quantitative and qualitative findings will be integrated to identify areas of agreement, differences across participant groups, and aspects of the protocol requiring revision. The final WI-CARE protocol will provide an evidence-informed approach for using WhatsApp to engage African immigrant communities throughout the research process.
