Communicating about clinical trials and medical research is challenging. An appropriate communication is essential to reduce some of the barriers associated with poor patients’ enrollment in clinical trials and with patients’ uninformed consent or uninformed refusal. An experiment was conducted to assess the effects of educational animations compared to brochures with and without visuals, and with the materials currently used by the NIH. These materials focused on explaining placebos, randomization, the steps necessary to enroll in a clinical trial, and how and by who patients’ protection is ensured. A total of 1194 cancer patients and survivors completed this 4 by 4 experiment through a Qualtrics panel. The findings showed that animations improved participants knowledge about and attitudes toward clinical trials and were more effective than brochures presenting information from the NIH, especially for those individuals with low motivation and low ability to comprehend health-related information. Several evidence-based theoretical explanations of the functioning of animations are provided.
