Technology-facilitated dating abuse among adolescents: victims, perpetrators, and bystanders
| Resumo: | Technology-facilitated dating abuse (TFDA), including its sexual forms (TFSDA), among adolescents, has received limited scientific and social attention. This thesis includes four empirical studies based on a school-based sample (N = 1,855; aged 12–18) and a scoping review (N = 6 studies). In Chapters I and II, the Technology-Facilitated Abuse in Relationships Scale (TAR) and the Scale for Reactive Bystander Opportunity Detection in TFSDA were validated for use in Portugal, demonstrating good psychometric properties. Prevalence rates for victimization (11.9%), perpetration (9.4%), and dual involvement (34.5%) were concerning. Cisgender girls were more often victim-perpetrators of monitoring/control behaviors, and adolescents aged 14–16 were more often victims of sexual coercion. TFDA was negatively associated with self-esteem and health-related quality of life and positively related to in-person dating violence. Image-based sexual harassment/abuse was the most frequently detected abusive typology by bystanders, with lower detection levels among cisgender girls and higher levels among older adolescents. Victims and victim-perpetrators of TFSDA detected more intervention opportunities. In Chapter III it was confirmed that the Theory of Planned Behavior is an effective model for predicting bystanders’ intentions to help victims of TFSDA. Identifying as a cisgender girl and exhibiting higher levels of empathy were positively associated with favorable attitudes and subjective norms toward helping, greater perceived control over helping, and increased intentions to help. TFDA victimization was positively associated with attitudes but negatively associated with subjective norms and perceived behavioral control. In Chapter IV four bystander classes were identified — Victim-centered helpers, Passive bystanders, Comprehensive helpers, and Inconsistent bystanders — distinguished by intraindividual factors, event characteristics, and intervention outcomes. In Chapter V it was found that, in the assessment of victims of technology-facilitated sexual abuse, forensic interviews that present victims with digital evidence of the abuse harmed both the quality of the testimony and the recovery process. Risk and trauma assessments tended to overlook this type of abuse, except when it was disclosed by the victim or flagged by child protection services. The discussion summarizes key findings, implications, limitations, and future directions. |
