This chapter narrows the gap between Internet technology and research ethics so that psychologists can strive to meet exemplary ethical standards and, at the very least, avoid many of the common ethical pitfalls of Internet-mediated research. Although advanced methodological issues are beyond the scope of this chapter, basic design considerations are explored to the extent that they are aligned with ethical decision making. Similarly, although the importance of Internet research is considered periodically throughout this chapter, relevant reviews would be more useful in highlighting the utility of this particular methodology (e.g., Birnbaum, 2001; Skitka & Sargis, 2006). Related topics involving the interaction between technology and ethics, such as telehealth and distance learning, are considered elsewhere in this handbook. Upon completing this review, the reader will have a greater understanding of basic terminology and technical issues, the online informed consent process, privacy and confidentiality protections, debriefing procedures, issues involving participant respect, beneficence and justice considerations, and resource allocation strategies necessary for conducting most Internet research studies in an ethical manner.
