Quantifying Toxic Friendship: A Preliminary Investigation of a Measure of Victimization in the Friendships of Adolescents

Although friendship is a key source of support and intimacy for adolescents, adolescent friendships can also involve victimization, which can be harmful to youth well-being. To date, our understanding of victimization in friendship has been limited by a lack of measures that comprehensively capture the variety of negative behaviors occurring in this relationship. This study outlines the development and preliminary validation of the Friendship Victimization Scale for Adolescents (FVS-A), which assesses victimization and controlling behaviors in adolescent friendships. Adolescents ( = 706, = 15.93, = 1.67; 62.3% cisgender girls, 33.7% cisgender boys) from high schools in Canada completed the FVS-A and other measures in the fall of 2019. The factor structure and psychometric properties of the measure were examined. The FVS-A demonstrated excellent internal consistency and a 3-factor structure (relational victimization, physical/verbal victimization, controlling behavior). There was evidence for demographic differences such that cisgender girls reported more overall friendship victimization, as well as relational victimization and control, than did cisgender boys. Greater friendship victimization was associated with greater dating victimization and gender-based bullying and was uniquely associated with greater depressive symptoms after accounting for these other types of victimization. Findings suggest that friendship victimization is common among adolescents. The results provide evidence for the utility of the FVS-A as a measure of an understudied source of interpersonal risk. Future work is needed to understand the long-term implications of friendship victimization and to elucidate the temporal associations between friendship victimization and other indicators of psychosocial adjustment.
