The development of digital computing and the growth of the Internet have opened up new opportunities to engage in online research. These online research practices involving human subjects, often involving relatively new technologies, can create tension between the online investigator and the Institutional Review Boards (IRBs) who are required to review and approve such research prior to data collection. This chapter aims to reduce this tension by discussing the associated ethics issues and applicable federal regulations, identifying specific concerns from the perspective of IRBs, and offering suggestions as to how best to address these concerns in applications in a way that can hopefully serve both the researcher and the review board.
