ABSTRACT
INTRODUCTION: Selective mutism (SM) is an anxiety disorder categorized by a persistent failure to speak in specific situations. In an attempt to facilitate interaction with individuals with SM, other forms of communication (e.g. computer-mediated communication; CMC) are often tried. However, CMC is understudied in individuals with SM, while, especially since the COVID-19 pandemic, the importance of CMC for education and social purposes only increased. METHODS: In this study, we explored CMC in 79 adolescents with either selective mutism (n = 34), or typical development (n = 45). All participants completed a survey concerning verbal and written CMC in three contexts (friends, family, and school). RESULTS: Results showed that adolescents with SM used not only verbal but also written CMC less frequently than the comparison group across contexts. While the comparison group preferred Face-to-Face communication over CMC, adolescents with SM were divided, especially in the school context. With family and friends, the majority of the SM group preferred Face-to-Face communication, even though this provoked more feelings of tension than CMC for part of the group. CONCLUSION: These findings support anecdotal reports that SM affects not only speech but extends to other communicative venues and includes written communication in many situations. This underlines the importance of addressing not just speaking behavior but also writing and CMC in the diagnostic evaluation and treatment plans for adolescents with SM.
