The aim of the present study was to analyze the role of minors' impulsiveness in the perpetration of child-to-parent violence (CPV), controlling for sex, age, interest allocated to studies, and participant´s and parent´s drug consumption habits, as well as to test the moderating role of the aggressor's sex on impulsiveness. The sample comprised 934 students from high school centers (438 boys and 496 girls), aged between 13 and 21 years. Impulsiveness was assessed through the Barratt's Impulsiveness Scale (BIS-11), whereas CPV perpetration was assessed employing the Child-to-Parent Aggression Questionnaire. Hierarchical multiple regression analyses showed that both attentional (β = .09, p < .05; β = .12, p < .001) and motor impulsiveness (β = .26, p < .001; β = .25, p < .001) were related to the perpetration of CPV. Interaction analyses showed a moderating role of the aggressor's sex over motor impulsiveness in the case of CPV towards the father (β = .29, p < .05), and over attentional impulsiveness in the case of CPV towards the mother (β = .45, p < .001). Results confirm the idea that minors' impulsiveness has an effect on the probability of CPV perpetration, which differs according to the sex of the perpetrator.

<p>The aim of the present study was to analyze the role of the psychopathologic symptomatology of participants on the perpetration of child-to-parent violence (CPV), as well as to test the moderator role of the participant sex on the psychopathology.</p><p>The sample comprised 855 students from middle school, high school and vocational education (399 boys and 456 girls). Age range varies among 13-21 years old (<em>M</em> = 16.09; <em>DT</em> = 1.34), being 307 (35.9%) among 13-15, 501 (58.6%) 16-18 and 47 (5.5%) 19-21. Most of them (91%) had Spanish citizenship. Psychopathology was assessed with the Symptom Checklist 90 Revised, whereas CPV perpetration was assessed employing the Child-to-Parent Aggression Questionnaire.</p><p>Hierarchical multiple regression analyses showed that the most important psychopathologic symptoms were hostility, paranoid ideation and depression, being related higher scores on hostility and paranoid ideation, and lower on depression, with the perpetration of CPV. Interaction analyses showed a moderator role of the participant sex with the interpersonal sensitivity and obsessive-compulsive in the case of CPV to the father, and interpersonal sensitivity, obsessive-compulsive and paranoid ideation in the case of CPV to the mother.</p><p>Results confirm the idea that the existence of psychopathologic symptomatology by the minors has an effect on the probability of perpetration CPV, being this effect different depending on the sex of the perpetrator.</p>
