Social media jealousy and intimate partner violence in young adults? romantic relationships: A longitudinal study

Social media have profoundly transformed young adults' social interactions, especially within their romantic relationships. For instance, jealousy induced by the partner's activity on social media can cause conflicts that can escalate into controlling and aggressive behaviors. Previous cross-sectional studies show significant links between social media jealousy and intimate partner violence (IPV) perpetration. However, the directionality of these associations has not yet been examined using longitudinal designs. This study investigated the associations between social media jealousy and IPV perpetration in young adults' romantic relationships over a year. Two samples, one composed of 111 couples (n = 222) and one composed of 286 individuals involved in a romantic relationship, completed online questionnaires at two time points over one year. Results of cross-lagged panel analyses were replicated across samples and suggested that the intra-individual association between social media jealousy and IPV perpetration is bidirectional and positive over time. Results also indicated a negative association between a person's IPV perpetration at Time 1 and their partner's online jealousy at Time 2. These findings highlight the reciprocal and dyadic influences of social media jealousy and IPV and provide a better understanding of the potential risks associated with social media use in young adults' romantic relationships.
