The scope of technology has allowed abusive behaviors in dating relationships to be experienced through electronic media and the internet. This study aimed to determine the existence of an association between cyber dating abuse (CDA) and intra-family relations (IR) in Mexican adolescent students adjusted for sex, alcohol use and face-to-face dating violence. The sample comprised 394 students between 15 and 18 years of age (62.4% women). It was found that 62.2% of the participants were victims of control/monitoring and 35% of direct aggression. All IR dimensions obtained intermediate scores. The structural equation model showed a negative association between CDA and IR with a small strength association (beta=-.18, p<.01). It would be advisable in CDA prevention programs to strengthen communication, union, support, and assertive conflict resolution in the family. Future studies should include other variables in the model to explain the CDA.
