Focus on smoking, diet and physical activity in Mexican Americans
The proposed study will evaluate the efficacy of a theoretically- and empirically-based, culturally-tailored Motivation And Problem Solving (MAPS) intervention, conducted within a community-based participatory research (CBPR) framework, for reducing cancer risk related to smoking, poor diet, and physical inactivity.

The specific aims of the study are to:

  1. Evaluate the efficacy of a Motivation and Problem Solving (MAPS) approach to promoting and facilitating cancer risk reduction among high-risk Mexican American individuals (overweight/obese smokers). Relative to Health Education, MAPS is hypothesized to result in positive changes in each of the primary smoking, diet, and physical activity outcomes.
  2. Assess the effects of MAPS on hypothesized treatment mechanisms (e.g., motivation, agency/self-efficacy, stress/affect) and the role of those mechanisms in mediating the effect of MAPS on outcomes.

The study will recruit participants from Mano a Mano, a long-term health study of people of Mexican origin living in Harris County.

Focus on biobanking and clinical trials
Identifying and understanding factors that influence Mexican-Americans’ participation in research studies and biobanking is critical for the development of educational materials aimed at increasing the number of Mexican-Americans with a clear understanding of biobanking, and willing to participate in research studies. The purpose of this pilot study is to describe socio-demographic, acculturation, and psychosocial factors that influence Mexican Americans to participate in research studies and to provide biologic specimens for biobanking.
