The purpose of this research was to determine the effectiveness of internet-delivered cognitive behavioral therapy (iCBT) in comparison to standard cognitive behavioral therapy in the treatment of depression and anxiety. The quality, safety, therapist-response, and cost of internet-delivered cognitive behavioral therapy was also studied. This review utilized multiple databases including PubMed, CINAHL, Clinical Key, Cochrane Library, and PsychINFO from 2015 to 2020. The literature reviewed consisted of peer-reviewed studies, randomized controlled trials, and systematic review. Sources that were excluded from the study included those prior to 2015, studies with small sample sizes, and those that involved children. Thirteen resources were selected for review. Much of the research suggested that iCBT is as effective as standard face-to-face therapy. Many authors thought it would be most useful as an adjunct to standard therapy which could ease accessibility issues. Other factors in considering the use of iCBT include therapeutic alliances, cost-effectiveness, and the varying qualities of the many different options. Internet-delivered cognitive behavioral therapy could be a viable alternative for cognitive behavioral therapy, but further research is needed.
