The Hispanic/Latino Adult Tobacco Survey (H/L ATS) is designed to measure the tobacco- related behaviors, knowledge, attitudes, and opinions of Hispanic and Latino persons. While the H/L ATS is based on the General Population State ATS and will generate comparable results, it is uniquely suited for administration among Hispanic/Latino populations: the questions asked and vocabulary used reflect the experience and language of Hispanic/Latino persons. In addition, the Spanish translation was carefully developed to be understood by Spanish-speakers from various countries of origin.
