#WhyIDidntReport my sexual violence and its effect on social support.

An analysis of social media posts using the #WhyIDidntReport hashtag reveals six themes regarding the reasons why survivors of sexual violence do not report the incident to health or social organisations such as police or supervisors. Using just-world theory as a means to examine social reactions to posts of victim's stories, we suggest the reasons for not reporting could be divided into clusters of internal or external barriers. Within the first cluster, three themes reflect survivors who did not report because of external reasons (e.g. victim blaming by the police or other institutions; minimisation of the seriousness of the crime; and reporting costs). In the second cluster, three themes reflect survivors who did not report because of internal reasons (e.g. self-blame, protecting others, and naivety). We find that survivors who did not report sexual violence because of external reasons received significantly more social support, whereas survivors who did not report because of internal reasons received significantly less social support in the form of shares and likes. Overall, these findings support our theorising that the reasons why survivors do not report sexual violence are impactful because, consistent with just-world theorising, they change perceptions of victimhood and therefore the level of social support.
