The relationship between parenting styles and teen dating violence has become a relevant research topic in recent years, especially related to violence inflicted online. To more fully understand this relationship, the objective of the present study was to examine which parenting style (authoritarian, indulgent, authoritative, or neglectful) best protects against dating violence in adolescent relationships. A total of 1132 adolescents of both sexes participated in this study (46.4% boys and 53.6% girls), with ages between 14 and 18 years old (M = 15.6, SD = 1.3). A multivariate factorial design was applied (MANOVA, 4 × 2), using the parenting style, the parents' gender, and the adolescents' gender as independent variables, and the dating violence dimensions (online and offline) as dependent variables. As the results show, the lowest scores on all the dating violence dimensions examined were obtained by adolescents from indulgent families. In addition, three interaction effects were observed between the mother's parenting style and the adolescent's gender on online violence (e-violence and control), and the father's parenting style on offline violence (verbal-emotional). Thus, adolescents with authoritarian mothers obtained the highest scores on violence and control inflicted online, respectively, and adolescent girls with authoritarian fathers obtained the highest scores on verbal-emotional violence. These findings suggest that the indulgent style is the parenting style that protects against violence in teen dating relationships, and they also highlight the risks of the authoritarian style as a family child-rearing model.
