Harnessing Digital Videos to Promote Cancer Prevention and Education: a Systematic Review of the Literature from 2013-2018.

Social media has transformed the way cancer patients search for information about their chronic health problems. The purpose of this systematic review is to identify the use of online digital videos to increase cancer knowledge and to understand information preference, behavioral changes, and attitudes towards online cancer education videos. The databases used for this review included MedLine, PsychINFO, and PubMed. These medical databases were used to locate peer-reviewed academic journals from 2013-2018 using the following MeSH terms: "cancer education videos," "cancer prevention videos," and "cancer education digital videos." A total of 4996 articles were retrieved from the initial search, and 33 articles were reviewed. Articles were excluded if videos did not (1) focus on cancer education and prevention; (2) posted on an online platform; and (3) assessed participants' knowledge, attitude, or beliefs about cancer. Eleven articles were found to meet inclusion criteria for final review. All of the studies focused on increasing education on preventive health behaviors (i.e., sunscreen use, smoking, and diet) and/or early detection strategies (i.e., screening testing and/or self-skin exams). While online digital health videos have the potential to improve health outcomes, issues related to technology access and health literacy must be considered when developing online health education videos.
