Dating violence is prevalent among Hispanic adolescents, yet few incidents are reported to the police. This research explored the severity of adolescent definitions as one potential reason for its under-reporting. It was expected that some adolescents might define only the most severe violence as “dating violence” and as a consequence these incidents are under-reported. Hispanic adolescent definitions of dating violence were examined along with factorsgeneral acceptance of dating violence, peer support of dating violence, acculturation, victimization experience, and sex-that might be related to the construction of these definitions. Acculturation, victimization experience, and sex were found to significantly contribute to the severity of adolescent definitions.
