Cancer Clinical Trials Education Program is offered to English- and Spanish-speaking Hispanics in the experimental arm. This program was designed to promote increased clinical trials literacy among Hispanic Americans. Increased clinical trials knowledge and a better understanding of clinical trials is anticipated to create more positive attitudes, and perceptions about clinical trials among Hispanic Americans.

The Neighborhood Watch Program created by the Bureau of Justice Assistance and the National Crime Prevention Council was selected for inclusion in the control arm of this study. It provided participants with a program of equivalent length and format, as well as an equivalent focus on improving the well-being of Hispanic Americans. It also provided an opportunity to evaluate the impact of the Neighborhood Watch Program.

Hispanic Americans are underrepresented in cancer clinical trials. The purpose of this study is to develop and test programs designed to reduce barriers and increase facilitators associated with cancer clinical trials participation for Hispanic Americans.

To assess the impact of the intervention arm on participants' knowledge, attitudes, and perceptions related to clinical trials, they were asked to complete the same surveys given at baseline during post-intervention immediately after intervention.

At the three-month follow-up, participants were mailed the final packet of survey instruments to complete and return in a stamped, self-addressed envelope.

Two weeks after receiving the intervention, participants were mailed an invitation to participate in a different research study by a researcher not previously known to them, to assess whether the intervention influenced behavior related to clinical trials invitations.
