We intend to understand more experiences of violence among Latinx immigrants in the US and methods to better engage this population in health research. Specific Aims include: 1. To develop and adapt quantitative survey instruments to assess interpersonal violence among Latino immigrants. Qualitative methods (focus groups and in-depth interviews) will be used to identify various forms and contexts of violence victimization experienced by Latinx immigrants that are not currently captured by existing instruments. Cognitive testing approaches will elicit feedback on selected instruments and pilot adapted methods.
