The present study, conducted on CRF patients in stages IV and V not undergoing dialysis, showed; (a) that a high percentage of these patients developed PAD (19%) or other vascular pathologies; (b) that there was an associated high mortality rate (29%) after 5 years; (c) that the 5-year mortality rate was significantly higher (P = 0.004) in PAD patients (64 vs 20%).

Child-to-parent violence (CPV) constitutes a serious social problem due to its short and long-term consequences, which not only directly affect the victim but also generate a rupture of the family system. In this study, direct and indirect effects of exposition to violence within the family, insecurity in the family system (manifested as disengagement and/or preoccupation), and justification of violence on CPV toward mothers and fathers were analyzed with structural equation modeling (SEM). Davies and Cummings emotional security theory (1994) was applied. A total of 904 high school students between 13 and 20 years old participated in this study. Information regarding each participant’s committed CPV was obtained from the Child-to-Parent Aggression Questionnaire. Emotional insecurity was assessed with the Security in the Family System scale. To assess exposition to violence and justification of violence, the Exposure to Violence Questionnaire and Irrational Beliefs Inventory for Adolescents were applied, respectively. Strong relationships between exposition to violence within the family, emotional insecurity, justification of violence, and CPV toward mothers and fathers were observed. The results show that adolescents who are exposed to violence at home are more aggressive in the future. In addition, this relationship is mediated, at least in part, by the justification of violence and emotional insecurity. These results suggest that prevention and treatment of CPV aggressors should focus on improving security within the survivors’ family system as well as modifying attitudes toward violence.

Research into the effects of violent video games on levels of aggression has raised concerns that they may pose a significant social risk, especially among younger people. The objective of this study was to analyze, through structural equation models, the mediating role of psychological engagement in the relationship between the consumption of violent video games and child-to-parent violence (CPV) against the mother and the father. The sample consisted of 916 students from the third and fourth grades of compulsory secondary education, first and second grades of high school, and first cycle of vocational training (483 males and 433 females), of whom a total of 628 were video game players, aged between 13 and 19. The exposure to video games was assessed through an author-elaborated questionnaire, engagement was evaluated with the game engagement questionnaire, and CPV was assessed through the child-to-parent aggression questionnaire. The structural equation models indicated that exposure to violent video games was related to lower rates of CPV against both parents. Conversely, the flow (a sense of being in control, being one with activity, and experiencing distortions in the perception of time) dimension of engagement positively correlated with the level of CPV against the mother, whereas the flow and absorption (total engagement in the current experience) dimensions correlated with CPV against the father. In conclusion, the results confirm the role of violent video game consumption, reducing CPV rates against both parents, a role that is offset to the extent that these violent games provoke engagement in the user.

The objective of this study was to analyze the relationship of the exposition to violence and justification of violence with child-to-parent violence (CPV) towards father and mother. Sample comprised 748 high school students (413 male and 335 female), between 13 and 20 years old. Childto-Parent Aggression Questionnaire (CPAQ) was employed to assess CPV. Exposition to violence in high school, home, street and television was assessed using the Violence Exposure Questionnaire (VEQ), whereas expostion to violence in videogames was assessed through a questionnaire prepared by the authors. Justification of violence was analyzed using the Justification of Violence subscale of the Irrational Beliefs Scale for Adolescents (ECIA).
