Read the detailed description

Hispanic Americans are underrepresented in cancer clinical trials. The purpose of this study is to develop and test education programs designed to reduce barriers and Increase facilitators associated with cancer clinical trials participation for Hispanic Americans. Focus groups were conducted with Hispanic American men and women to obtain culturally-linked attitudes related to clinical trials participation. This information was used to create a prototypic educational program anticipated to increase participation in clinical trials. It was then vetted and honed via additional focus groups.

Simultaneously, a validation study was conducted with Hispanic Americans for a packet of psychosocial instruments that could be used for a subsequent randomized controlled trial to evaluate the impact of the clinical trials education program.

The finalized clinical trials education program was tested via a randomized controlled trial. Participants assigned to the experimental group received the clinical trials education program, while participants in the control arm were administered a comparable, but non-relevant education program. Recruitment to this study has been completed.

Study arms

  • Experimental
    Cancer Clinical Trials Education Program

    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.

    Behavioral: Cancer Clinical Trials Education Program

  • Placebo comparator
    Neighborhood Watch Education Program

    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.

What researchers measure

Primary outcomes

  1. Change in Participants' Clinical Trials-Related Knowledge, Attitudes and Beliefs From Baseline to First Follow-up

    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.

    Time frame: Change from baseline to first follow-up (immediately after receiving intervention)

  2. Change in Participants' Clinical Trials-Related Knowledge, Attitudes and Beliefs From Baseline to Second Follow-up

    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.

    Time frame: Change from baseline to second follow-up (three months after receiving intervention)

Secondary outcomes

  1. Willingness to Participate in Research

    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.

    Time frame: Two weeks after receiving intervention
