Co-Occurring Cyberbullying and School Bullying Victimization and Associations With Mental Health Problems Among Canadian Middle and High School Students.

This study examined the associations between co-occurring cyberbullying and school bullying victimization with poor self-rated mental health, psychological distress, and suicidal ideation and attempts among 4,886 Canadian students in Grades 7-12 and tested whether these associations differed between middle and high school students. There are 12.2% of students who were victims of both cyberbullying and school bullying. After adjusting for covariates, victims of both cyberbullying and school bullying presented the highest odds of poor self-rated mental health (odds ratio [OR] = 5.02; 95% CI [3.75, 6.74]), psychological distress (OR = 5.91; 95% CI [4.38, 7.96]), and suicidal ideation (OR = 6.17; 95% CI [4.44, 8.56]) and attempts (OR = 7.68; 95% CI [3.95, 14.93]). These associations were stronger among middle-school youth than their high school counterparts. Results suggest that victims of both cyberbullying and school bullying may constitute the most vulnerable group and that there is a need for intervention programs addressing both forms of bullying simultaneously, particularly among middle school students.
