Summary

Hypothesis: More than 80% of the participants (n=40) will complete the intervention at three month (intervention completion) and the six month follow-up (retention rate as feasibility). More than 70% of the participants will report high overall study satisfaction (acceptability) with the intervention and study. This pre-pilot will inform intervention and procedural refinements for the pilot. Hypothesis: Participants who receive the intervention (n=57) will report more skin cancer-related preventive behaviors (e.g., mean of summed score of sun protection behaviors such as use of sunscreen, etc.) at three month and six month follow-up compared to those in the control condition (n=57, who will receive general information about physical activity and nutrition).

Detailed description

Aim 1: The investigator will conduct individual interviews among key stakeholders such as health care providers and community leaders to plan a mobile skin cancer intervention among Hispanics. Data will be collected from individual interviews (n=10-12) among key stakeholders and triangulated with data from a funded pilot grant (focus groups and surveys with Hispanic community members) to gather information regarding Hispanics perceptions and behaviors related to skin cancer and suggestions for a WhatsApp intervention. Aim 2: Employing a user-centered approach to develop a WhatsApp intervention to promote skin cancer risk-reduction behaviors among Hispanics and encourage engagement in the intervention. Use an iterative qualitative (focus groups with Hispanics, n=32; individual interviews with key stakeholders e.g., health care providers and community leaders, n=10-12) process to incorporate input from Hispanics and relevant stakeholders to develop a mobile WhatsApp intervention that is theory- and culturally-guided. Aim 3: The investigators will evaluate the feasibility and acceptability of this mobile intervention in a single-arm pre-, post-test pilot study among at-risk Hispanics. Aim 4: Refine the intervention and conduct a pilot RCT (n = 114) using this mobile program among Hispanics at risk for skin cancer and assess the preliminary effects of the mobile intervention at 3-month (intervention completion) and 6-month follow-ups.

Interventions

Type	Name	Description
BEHAVIORAL	Hispanics Skin Cancer intervention	With the insights from the community, the investigators will then develop the mobile intervention targeting Hispanics at risk for skin cancer to promote sun protection and SSE and get feedback to optimize the intervention. After the random allocation participants will receive instructions on how to use WhatsApp and then the intervention. They will receive WhatsApp messages about skin cancer for three months with optimal frequencies determined by prior aims and complete a post-intervention survey which contains the same questions in the pre-survey. The pilot RCT will be conducted around the spring/summer of Year four of the R00 when UVR is generally the highest in the US. The participants will be contacted at six months after the baseline survey to complete another survey similar to the post-intervention survey.
BEHAVIORAL	Control group: physical activity and nutrition for Hispanics	Content will be developed from established websites such as CDC's Division of Nutrition, Physical Activity and Obesity. We selected these topics because they are also of concern among Hispanics and provide an unrelated attention control.
