Data Collection and Participants

Self-administered survey data were collected from January to April in 2017. Participants were the age of 18 or older and were able to read and speak English or Spanish. All survey materials were available in English and Spanish. English materials were translated into Spanish by a translator. Another translator back-translated the materials to ensure accuracy of the forward-translation. The third translator verified the accuracy of the translation. Sampling was based on a convenience sample. Participants were recruited by research assistants in the waiting room of the clinic by convenience sampling. All potentially eligible patients in the waiting room were approached by a research assistant. If a patient expressed an interest in participating in the survey, he or she received a consent cover letter and a survey instrument. Informed consent was obtained from each participant. Participants received a small gift (approximately US $1 or less value) such as sample shampoo, conditioner, and/or lotion at the completion of the survey. Since the gifts were on the same table with the survey materials, it is reasonable to assume that the majority of the participants knew about a gift.
