This article presents the first systematic review on intimate partner violence (IPV) in self-identified lesbians in same-sex couples. Studies published from January 1990 to December 2013 were analyzed. Of the 687 studies reviewed, 59 were preselected, of which 14 studies were selected that met the inclusion and methodological quality criteria. A summary is presented of the characteristics of the studies, the participants, the prevalence of IPV victimization and perpetration, and its correlates. All the studies were carried out in the United States and used a nonprobabilistic sampling method. The majority of participants were White with a high educational level. The results indicate that all the forms of violence occur, but the most prevalent is emotional/psychological violence. The correlates positively associated with IPV are certain personality characteristics, fusion, previous IPV experience, a family history of violence, and alcohol consumption. This review finds significant limitations in the analyzed literature. Methodological recommendations are made for future studies.

Children use the Internet at an increasingly younger age and many parents do not have the necessary knowledge to protect or guide them. A previous study showed that 78% of children between the ages of 6 and 9 used the Internet and that their parents were usually with them, but 40% of these children would surf at some point without supervision. This research aims to examine the relationship between the parents' digital competence and the different elements included in the parental mediation process. The sample is made up of 1827 parents who answered the survey. A relationship is observed between the parents' level of education and their digital competence. The results show that for parents with greater digital competence it is more likely that their 6-to 9-year-olds are already surfing the Internet. They also supervise more frequently and have more knowledge of the online activities that their children carry out.

This study aimed to investigate the influence of parental gender on their interaction with their infants, considering, as well, the role of the infant’s gender. The State Space Grid (SSG) method, a graphical tool based on the non-linear dynamic system approach (NDS) was used to analyze the interaction, in Free-Play setting, of 52 infants, aged 6 to 10 months, divided into two groups: half of the infants interacted with their fathers and half with their mothers. There were 50% boys in each group. MANOVA results showed no differential parenting of boys and girls. Additionally, mothers and fathers showed no differences in the Diversity of behavioral dyadic states nor in Predictability. However, differences associated with parent’s gender were found in that the paternal dyads were more "active" than the maternal dyads: they were faster in the rates per second of behavioral events and transitions or change of state. In contrast, maternal dyads were more repetitive because, once they visited a certain dyadic state, they tend to be involved in more events. Results showed a significant discriminant function on the parental groups, fathers and mothers. Specifically, the content analyses carried out for the three NDS variables, that previously showed differences between groups, showed particular dyadic behavioral states associated with the rate of Transitions and the Events per Visit ratio. Thus, the transitions involving ‘in-out’ of ‘Child Social Approach neutral - Sensitive Approach neutral’ state and the repetitions of events in the dyadic state ‘Child Play-Sensitive Approach neutral’ distinguished fathers from mothers. The classification of dyads (with fathers and mothers) based on this discriminant function identified 73.10% (19/26) of the father-infant dyads and 88.5% (23/26) of the mother-infant dyads. The study of father-infant interaction using the SSG approach offers interesting possibilities because it characterizes and quantifies the actual moment-to-moment flow of parent-infant interactive dynamics. Our findings showed how observational methods applied to natural contexts offer new facets in father versus mother interactive behavior with their infants that can inform further developments in this field.
