Myth Acceptance Regarding Male-To-Female Intimate Partner Violence amongst Spanish Adolescents and Emerging Adults

(1) Background: General beliefs and attitudes toward Male-to-Female Intimate Partner Violence (MFIPV) play a fundamental, critical role in the expression of violent behaviors in relationships during both adolescence and adulthood. The objective of the present study was to contrast the degree of myth acceptance regarding MFIPV, based on the sex and age of Spanish teenagers and emerging adults. (2) Methods: A sample of 1580 participants aged between 15 and 24 took part in the study. The subjects were enrolled in 34 secondary schools and two university centers spread across Seville (Spain). A multivariate analysis of variance (MANOVA) was carried out for the data analysis. (3) Results: Overall, males had a higher level of myth acceptance than females in all the dimensions considered in the study. In the case of significantly high levels of myth acceptance, males quintupled females. The research dimension that revealed the greatest differences was romantic love. Regarding age, a degree of stability was observed in the age period of 15–17 years and 18–20 years, but this subsequently decreased for the age range of 21–24 years. (4) Conclusions: Efforts should be focused on promoting actions to challenge male mandates and narratives concerning romantic or true love.
