These differential tendencies of aggression typology for men and women help clinicians to develop preventive interventions for every age, with the aim of diminishing their continuity in future relationships.

Addiction to and problematic use of the Internet are relatively recent phenomena whose scope, characteristics and correlates have begun to receive increasing attention by clinicians and researchers alike. The purpose of this study was to examine the relationship between time spent connected to the Internet and the variables that indicate a pathological and addictive use of this technological resource. The sample was comprised of 1,301 university students of both sexes (927 women and 374 men), with ages ranging from 18 to 30 years old. The results showed that, although most people use the Internet appropriately, users who invest higher quantities of time in the Internet more frequently exhibit connection behavior that is controlled through negative reinforcement, a high degree of arousal when online, loss of control over connection behavior, changes in health-related habits, and interference in the social, family, academic, or work spheres. These findings suggest that excessive Internet use is associated with the onset of several problems that are similar to those associated with other behavioral and technological addictions.

This study explores the existence of different types of batterers in a sample of 266 men who had been court referred for intimate partner violence. The data collected in the assessment that have been used to perform a hierarchical and a two-step cluster analysis fall into three areas: aggression towards the partner, general aggression and presence of psychopathology and personality traits, more specifically, alcohol use, borderline and antisocial personality traits, psychopathy traits, state anger and trait anger, anger expression and control, anger, hostility, and, finally, impulsivity. The results show a typology consisting of 3 types of batterers on the basis of violence level and psychopathology: low (65%), moderate (27.8%) and high (7.1%). This study provides empirical support for the development of batterer typologies. These typologies will help achieve early detection of different types of batterers, allowing us to tailor interventions on the basis of the needs of each of the types.

Prevention programs for dating partner aggression should be based on knowledge about when such aggression starts and how it changes. Given the very few studies regarding such trends, changes in physical, psychological, and sexual aggression against dating partners were examined in 14- to 20-year-old Spanish high school students (N = 2,016). Overall, psychological aggression increased linearly, whereas physical aggression had a negative quadratic association, peaking at 16 to 17 years for males and females. Sexual aggression was infrequent, but it spiked at age 16 for males. Although physical aggression diminished in late adolescence, injuries as a consequence of such aggression increased linearly for females, and they were also significantly higher for females (14.9%) than for males (3%) at ages 18 to 20 years. The findings support the hypothesis that dating physical aggression for males and females peaks during middle-to-late adolescence and shows a similar developmental pattern to other antisocial and criminal behaviors. Prevention of dating aggression, escalation of such aggression, and prevention of injury should consider developmental trends in dating aggression.
