Non-suicidal self-injury (NSSI) is of concern given the increased risk for suicide attempt. Prevalence rates of NSSI are highest among adolescents and young adults. These groups also exhibit the highest rates of Internet use. Previous research suggests that online communication of NSSI can serve as both a risk and protective factor related to NSSI engagement. This study explored online disinhibition in the context of NSSI e-communities as a potential factor that could contribute to opposing NSSI outcomes.
The study sample consisted of 200 individuals 18 years or older (M = 21.76, SD = 5.24) recruited from social networking sites (i.e., Reddit, LiveJournal). These participants provided self-report of their NSSI histories and degree of online disinhibition.
Those who engaged in Internet communication of NSSI at the highest level endorsed more online disinhibition than those less involved with NSSI content. Furthermore, within this group of high communicators, increased toxic disinhibition predicted lower lifetime frequency of NSSI.
This study suggests that online behavior, including toxic disinhibition, may contribute to NSSI outcomes. Online disinhibition and its relationship to NSSI should be an area of continued research. Cyberbullying may be an additional construct of interest in future studies of NSSI e-communication.
非自杀性自伤（NSSI）令人担忧，因为它会增加自杀企图的风险。NSSI 的患病率在青少年和年轻人中最高。这些群体也表现出最高的互联网使用率。先前的研究表明，NSSI 的在线交流既可以是与 NSSI 参与相关的风险因素，也可以是保护因素。本研究探讨了 NSSI 电子社区中的在线去抑制作用，作为可能导致相反 NSSI 结果的潜在因素。
研究样本由 200 名 18 岁或以上的个体组成（M=21.76，SD=5.24），他们是从社交网站（即 Reddit、LiveJournal）招募而来。这些参与者提供了他们的 NSSI 历史和在线去抑制程度的自我报告。
那些在互联网上交流 NSSI 的程度最高的人比那些较少涉及 NSSI 内容的人表现出更多的在线去抑制。此外，在这群高交流者中，毒性去抑制的增加预测了 NSSI 的终生频率降低。
这项研究表明，在线行为，包括毒性去抑制，可能会影响 NSSI 的结果。在线去抑制及其与 NSSI 的关系应该是一个持续研究的领域。网络欺凌可能是未来 NSSI 电子交流研究中另一个值得关注的构念。
