Waiving parent permission can be an option in some epidemiological and social research with adolescents. However, exemptions have not been uniformly considered or applied. Our aim is to critically assess the different factors that could be taken into account when making decisions about waiving active parental permission in observational research with adolescents.

The increased interest on measuring violence in romantic relationships has led to the identification of some risk factors for intimate partner violence (IPV) in its different forms. Some of them are often present from the onset of the relationships. However, little attention has been paid to the engagement period. This might be, in part, due to the cognitive dissonance that hinders partners reporting intimate violence when they are planning their wedding. The purpose of our study is to test the association between the individual perception of relationship power imbalance (RPI)—a possible indirect measure of intimate violence—and known predictors of IPV. To test this hypothesis, a total of 254 premarital couples taking part in a dynamic prospective cohort study completed a questionnaire with questions about the perception of RPI and referred predictors of IPV. Results showed a positive correlation between the perception of RPI and known predictors of IPV. These findings suggest that RPI is a powerful indirect measure to detect situations that might imply a mild form of IPV and that could evolve into stronger presentations of violence later in marriage. Noticing the presence of RPI before marriage could encourage the prevention and development of personal and relational strategies to avoid the consolidation of violent dynamics within the marital relationship.

Background: Intimate partner violence (IPV) and sexual violence (SV) are significant problems world-wide, and they affect women disproportionally. Whether individuals with attention-deficit/hyperactivity disorder (ADHD) are at an increased risk of being involved in these types of violence is unclear.Methods: We carried out a systematic review and meta-analysis (PROSPERO registration CRD42022348165) of the associations between ADHD and being the victim or perpetrator of IPV and SV. Ratios of occurrence of violence were pooled in random-effects models and study risk of bias was evaluated using the Newcastle–Ottawa Scale.Results: A search on multiple databases, carried out on 7 October 2022, yielded 14 eligible studies (1 111 557 individuals). Analyses showed a higher risk of ADHD individuals being involved in IPV as perpetrators (six studies, OR 2.5, 95% CI 1.51–4.15) or victims (four studies, OR 1.78, 95% CI 1.06–3.0). Likewise, individuals with ADHD were at increased risk of being perpetrators (three studies, OR 2.73, 95% CI 1.35–5.51) or victims of SV (six studies, OR 1.84, 95% CI 1.51–2.24). Results were overall robust to different analytical choices.Conclusions: Individuals with ADHD are at an increased risk of being involved in cases of violence, namely IPV and SV, either as victims or perpetrators. Although the causal path or mediating variables for these results are still unclear, this increased risk should inform evidence-based psychoeducation with individuals with ADHD, their families, and partners about romantic relationships and sexuality.

Recent studies have shown different results in identifying which parenting style is the most beneficial for children, which has encouraged certain authors to wonder whether parental control is still needed for optimal parenting. As such investigations have been conducted with different measuring instruments, it is necessary to check whether the use of different instruments leads to different results. In order to figure this out, a systematic review of the recent literature (Web of Science and Scopus, 2000–2017) was carried out. This review found that, using certain instruments, parental control is associated with better outcomes in children, while using certain others, control is associated with worse outcomes. The difference seems to be in the way of measuring parental control.
