Anal cancer incidence is higher in persons living with HIV/AIDS (PLWHA) than in the general population. Participation of PLWHA in anal cancer clinical trials (CTs) is essential; Hispanic PLWHA are underrepresented in CTs. We conducted a behavioral CT among 305 PLWHA in Puerto Rico to measure the efficacy of an educational video in increasing calls and screening into an anal cancer CT. Participants received printed educational materials on anal cancer and CTs; the intervention group also received an educational video. Outcome assessment based on follow-up interviews showed that printed materials increased awareness about CTs and high-resolution anoscopy (HRA), and willingness to participate in an anal cancer CT in both groups. However, the addition of the video increased the likelihood of participants to call the CT for orientation (RRadjusted = 1.66, 95% CI 1.00–2.76; p = 0.05) and pre-screening evaluation (RRadjusted = 1.70, 95% CI 0.95–3.03; p = 0.07). This intervention could help increase participation of Hispanics into anal cancer-related CTs.ResumenEl cáncer anal es más común en personas con VIH/SIDA que en la población general. La participación de estas personas en ensayos clínicos (ECs) es esencial; los hispanos están sub-representados en los ECs. Realizamos un EC en 305 personas con VIH/SIDA en Puerto Rico, para medir la eficacia de un video educativo en aumentar las llamadas y el cernimiento a un EC de cáncer anal. Los participantes recibieron material impreso sobre cáncer anal y ECs; el grupo de intervención también observό el video educativo. Los resultados mostraron que los materiales impresos aumentaron la concienciación sobre ECs y la anoscopía, y la disposición de participar en un EC de cáncer anal. Sin embargo, el video educativo aumentό la posibilidad de que los participantes llamaran para orientación (RRajustado = 1.66, 95% CI 1.00–2.76; p = 0.05) y evaluación (RRajustado = 1.70, 95% CI 0.95–3.03; p = 0.07) para un ECs de cáncer anal. Esta intervención puede ayudar a aumentar la participación de Hispanos en ECs de cáncer anal.
