Gender Inclusive Rape Myth Acceptance Scale: Evidence of Validity and Reliability in a Portuguese Community Sample

Area of Science:

• Psychology
• Sociology
• Criminology

Background:

• Existing research on sexual violence myths often overlooks diverse victim profiles, primarily using college samples.
• There is a need to assess myth endorsement across broader community populations.

Purpose of the Study:

• To validate the Gender Inclusive Rape Myth Acceptance (GIRMA) scale in a Portuguese community sample.
• To examine factors associated with sexual violence myth endorsement in a diverse adult population.

Main Methods:

• Confirmatory factor analysis was used to assess the GIRMA scale's structure.
• Convergent and divergent validity and reliability were evaluated in a sample of 518 Portuguese adults.
• Demographic, attitudinal, and experiential factors related to sexual violence myth endorsement were analyzed.

Main Results:

• The study provided evidence for the validity and reliability of the GIRMA scale's one-factor model in the Portuguese context.
• Males, heterosexuals, older individuals, those with lower education, higher sexism, and social dominance orientation were more likely to endorse myths.
• Personal experience with sexual violence (as a victim or knowing a victim) was associated with lower myth endorsement.

Conclusions:

• The GIRMA scale is a reliable instrument for assessing sexual violence myths in Portuguese-speaking communities.
• Findings highlight the need for inclusive victim protection policies and prevention programs.
• Understanding factors influencing myth endorsement is crucial for community and professional settings.
