Measures

    Two ad hoc instruments were created because of the lack of scales focused on the aim of this study. The published questionnaires we consulted had focused on perpetration or victimization, but not both. Thus, the first instrument assessed abusive behavior (experienced and perpetrated) based on previously validated questionnaires (i.e., CUVINO, CTS). The resulting instrument was composed of twenty dichotomous items concerning the experience and perpetration of physical, psychological, and relational violence.
    To examine the acceptance of the myths of romantic love in adolescents, a second scale was created. Previous questionnaires were aimed at assessing biased ideas from a cognitive-behavioral perspective that were incompatible with the aims of this study. The resulting scale was composed of 25 dichotomous items (true/false) about the most reported myths in the literature. Two independent researchers analyzed each item for classification within five categories: jealousy, emotional dependency, exclusivity, self-sacrifice (i.e., prioritizing the needs of the significant other and sacrifice of personal space), and sexist beliefs. The instruments used in this study can be requested from the authors.
