Social reactions to the disclosure of sexual victimization are critical to post-assault recovery. The popular social media hashtag "#MeToo" resulted in numerous survivors of sexual victimization disclosing their experience online. Whereas previous research has examined the association between social reactions to in-person disclosure of sexual victimization and factors commonly associated with adjustment among survivors - such as coping and social support - research is needed to examine correlates of social reactions to online disclosure of sexual victimization. Accordingly, the current study investigated the relationship between online social reactions to the disclosure of sexual victimization via #MeToo and engagement in various coping strategies (problem-focused coping, emotion-focused coping) and social isolation among a sample of 195 adults with a history of sexual victimization. Results indicated that the provision of online resources was associated with lower use of problem-focused and emotion-focused coping strategies. Receipt of online emotional and informational support was associated with increased use of emotion-focused coping strategies. Further, receipt of online social reactions that turned against the survivor and receipt of online social reactions that "made fun of you, insulted you, or said something to hurt you" were associated with higher levels of social isolation. Lastly, online unsupportive acknowledgment and "sharing your tweet with other people" were associated with lower levels of social isolation. Results highlight how online social reactions to disclosure of sexual victimization via #MeToo intersect with coping and social support among survivors of sexual victimization and help to give context to the experience of online disclosure of sexual victimization.
