Beliefs and violent behavior in interpersonal relationships of young adults: a systematic review

Beliefs are information-processing structures formed along an individual’s developmental pathway. Beliefs can legitimize involvement in inappropriate or violent behaviors, particularly when they crystallize into cognitive schemas. While beliefs aid individuals in interpreting the surrounding world, overly rigid and inflexible beliefs can constrain the individual’s ability to process available information. This Systematic Review, carried out according to the PRISMA norms and guidelines, aims to understand the most prevalent beliefs regarding relationships among young adults and to examine their associations with violent or deviant behaviors. Articles included in this review were retrieved from the EBSCO, PubMed, and Web of Science databases in July 2022, resulting in a total of 594 studies, which were subsequently screened by two independent reviewers. A total of 51 studies were then selected for full reading, but 36 were excluded based on pre-defined eligibility criteria, leaving a final sample of 18 studies published between 2014 and 2022. The main objectives, country of origin, instruments used, sample composition and age, main results and conclusions were extracted from each study. Findings point toward the presence of related and legitimate beliefs about violence in intimate relationships, domestic violence, sexual violence, acceptance of the rape myth, or consent to engage in sexual activities.
