Adolescent dating and relationship violence (DRV) is widespread and associated with increased risk of subsequent poor mental health outcomes and partner violence. Shifting social norms (i.e., descriptive norms of perceived behavior and injunctive norms of acceptable behavior among a reference group of important others) may be important for reducing DRV. However, few DRV studies assess norms, measurement varies, and evidence on measure quality is diffuse. We aimed to map and assess how studies examining DRV measured social norms concerning DRV and gender. We conducted a systematic review of DRV literature reporting on the use and validity of such measures among participants aged 10-18 years. Searches included English peer-reviewed and grey literature identified via nine databases; Google Scholar; organization websites; reference checking; known studies; and expert requests. We identified 24 eligible studies from the Americas (N = 15), Africa (N = 4), and Europe (N = 5) using 40 eligible measures of DRV norms (descriptive: N = 19; injunctive: N = 14) and gender norms (descriptive: N = 1; injunctive: N = 6). No measure was shared across studies. Most measures were significantly associated with DRV outcomes and most had a defined reference group. Other evidence of quality was mixed. DRV norms measures sometimes specified heterosexual relationships but rarely separated norms governing DRV perpetrated by girls and boys. None specified sexual-minority relationships. Gender norms measures tended to focus on violence, but missed broader gendered expectations underpinning DRV. Future research should develop valid, reliable DRV norms and gender norms measures, and assess whether interventions' impact on norms mediates impact on DRV.
