The purpose of this exploratory study is to examine factors associated with frequency and type of internet and mobile technology use among illegal drug users, specifically use of internet and text-messaging to obtain health care information and engage in health care utilization, specifically human immunodeficiency virus (HIV) prevention and treatment services. We will target high drug activity neighborhoods in New York City and enroll participants recruited through targeted street outreach. All participants (n=336) will undergo an audio computer-assisted self-interview (ACASI) that will assess socio-demographics, health care access and utilization, sex/drug use behavior, health status, and characteristics of general and health-related internet/mobile technology use including factors that promote or hinder use. Participants identified as using the internet ≥1/month (n=151) will return for a 4-week ACASI to report on use of the pilot website (which will largely display information currently available in the community in print/ pamphlet/ video form).

Arms Assigned Interventions
Website access
While this pilot intervention is not a randomized trial, study participants who report internet use at least once a month will told of a pilot website that they will be able to access for a 4-week study period. This website will contain a educational information tailored to the health needs of drug users. Web content will be similar to materials and public health messages released by the NYC Department of Health and therefore, harm is not likely to arise from viewing such content.
Other: Pilot Health Website

The pilot health website will contain educational health information such as:

health-related videos, searchable map of HIV prevention and other needed health and social services, and the option to register for automatic text message updates on relevant health information.

No Intervention: No website access
Participants who report internet use less than once a month will not receive access to the pilot website.
