Sexual Victimization in Contexts of Chemsex
Chemsex, understood as a form of sexualized drug use that involves a range of psychoactive substance and sociocultural contexts, has been associated with various physical and psychological risks. Among these, sexual victimization remains a critical yet underexplored issue. This scoping review synthesizes literature on sexual victimization in chemsex to identify key patterns, risk factors, and research gaps. A systematic search was conducted in mu…
Stability of Cybergrooming Victimization Among Adolescents
Given the high prevalence and potential harms of cybergrooming, understanding distinct patterns and the stability of victimization experiences among adolescents is imperative. Therefore, this one-year longitudinal study examined latent classes of cybergrooming and their stability. The sample consisted of 688 Spanish adolescents (56% girls, 88.5% heterosexual) with a mean age of 13.86 years (SD = 1.22). At both time points, latent class analysis w…

Psychological Flexibility and Inflexibility of University Students
In the Hexaflex model of Acceptance and Commitment Therapy (ACT), psychological flexibility refers to the ability to openly embrace difficult thoughts and emotions while acting in alignment with personal values. In contrast, psychological inflexibility involves rigid avoidance and control strategies that hinder adaptive functioning. Although previously studied, more culturally relevant evidence is needed to inform interventions that promote well-…

From hate speech to HateLess. The effectiveness of a prevention program on adolescents’ online hate speech involvement
Hate speech, a societal scourge, has found a potent conduit in modern technology, exacerbating its reach and impact. Adolescents are particularly vulnerable to the pernicious effects of online hate speech, which threaten their well-being and social cohesion. Addressing this critical issue, the current study uses a quasi-experimental design to evaluate the efficacy of “HateLess. Together Against Hatred” in reducing adolescents’ online hate speech …
Individual and Contextual Correlates of Latent Bystander Profiles toward Racist Hate Speech
Prior research into bystander responses to hate speech has utilized variable-centered analyses — such approaches risk simplifying the complex nature of bystander behaviors. Hence, the present study used a person-centered analysis to investigate latent hate speech bystander profiles. In addition, individual and classroom-level correlates associated with the various profiles were studied. The sample included 3225 students in grades 7–9 (51.7% self-…

A mixed-methods approach was employed…
Effects of the Prevention Program “HateLess. Together against Hatred” on Adolescents’ Empathy, Self-efficacy, and Countering Hate Speech
Currently, there is a lack of empirically evaluated prevention programs targeting hate speech among adolescents. This is problematic because hate speech jeopardizes adolescents’ well-being and social integration. To this end, this study aims to evaluate the short-term effects of the newly developed anti-hate speech prevention program, “HateLess. Together against Hatred”, on adolescents’ empathy, self-efficacy, and counter-speech. Eight hundred an…
Online Hate Speech Victimization and Depressive Symptoms Among Adolescents
Online hate speech has become a widespread problem in the daily life of adolescents. Despite growing societal and academic interest in this online risk, not much is known about the relationship between online hate speech victimization (OHSV) and adolescents' mental well-being. In addition, potential factors influencing the magnitude of this relationship remain unclear. To address these gaps in the literature, this study investigated the relations…
Assessing image‐based sexual abuse
INTRODUCTION: The aim of this study is to develop a new measure of victimization and perpetration of two frequent forms of image-based sexual abuse, namely sextortion (i.e., the threat of distributing sexual images to pressure the victim into doing something) and nonconsensual sexting (i.e., distributing sexual images of someone without the consent of the victim). Additional aims were to analyze the prevalence of these forms of victimization and …

Adolescents’ motivations to perpetrate hate speech and links with social norms
Hate speech has become a widespread phenomenon, however, it remains largely unclear why adolescents engage in it and which factors are associated with their motivations for perpetrating hate speech. To this end, we developed the multidimensional “Motivations for Hate Speech Perpetration Scale” (MHATE) and evaluated the psychometric properties. We also explored the associations between social norms and adolescents’ motivations for hate speech perp…
Prevalence and Association of Sexting and Online Sexual Victimization Among Spanish Adults
Predictors of child-to-parent aggression
Although we rarely hear about it, children sometimes aggress against their parents. This is a difficult topic to study because abused parents and abusive children are both reluctant to admit the occurrence of child-to-parent aggression. There are very few research studies on this topic, and even fewer theoretical explanations of why it occurs. We predicted that exposure to violence in the home (e.g., parents aggressing against each other) and ine…
