Barriers and Facilitation Measures Related to People With Mental Disorders When Using the Web: A Systematic Review

BACKGROUND: Mental disorders (MDs) affect almost 1 in 4 adults at some point during their lifetime, and coupled with substance use disorders are the fifth leading cause of disability adjusted life years worldwide. People with these disorders often use the Web as an informational resource, platform for convenient self-directed treatment, and a means for many other kinds of support. However, some features of the Web can potentially erect barriers for this group that limit their access to these benefits, and there is a lack of research looking into this eventuality. Therefore, it is important to identify gaps in knowledge about “what” barriers exist and “how” they could be addressed so that this knowledge can inform Web professionals who aim to ensure the Web is inclusive to this population. OBJECTIVE: The objective of this study was to provide an overview of existing evidence regarding the barriers people with mental disorders experience when using the Web and the facilitation measures used to address such barriers. METHODS: This study involved a systematic review of studies that have considered the difficulties people with mental disorders experience when using digital technologies. Digital technologies were included because knowledge about any barriers here would likely be also applicable to the Web. A synthesis was performed by categorizing data according to the 4 foundational principles of Web accessibility as proposed by the World Wide Web Consortium, which forms the necessary basis for anyone to gain adequate access to the Web. Facilitation measures recommended by studies were later summarized into a set of minimal recommendations. RESULTS: A total of 16 publications were included in this review, comprising 13 studies and 3 international guidelines. Findings suggest that people with mental disorders experience barriers that limit how they perceive, understand, and operate websites. Identified facilitation measures target these barriers in addition to ensuring that Web content can be reliably interpreted by a wide range of user applications. CONCLUSIONS: People with mental disorders encounter barriers on the Web, and attempts have been made to remove or reduce these barriers. As forewarned by experts in the area, only a few studies investigating this issue were found. More rigorous research is needed to be exhaustive and to have a larger impact on improving the Web for people with mental disorders.
