Resumen

Identifying dysfunctional beliefs about romantic relationships is important for fostering healthy relationship dynamics. This study aimed to translate into Spanish and verify the psychometric properties of the Rela-tionship Belief Inventory (RBI) in community samples from Spain and Mexico. A two-phase study was conducted: Phase I involved translation, while Phase II focused on psychometric analysis. The results showed that an 18-item scale considering only three beliefs (“Disagreement is destruc-tive”, “Mindreading is expected”, and “Sexes are different”) fit better than the original proposal. Validity was also supported by correlations with neu-roticism, relationship power imbalance, and parents’ relationship; as well as by group differences between clinical and community samples, and be-tween men and women. Internal consistency was confirmed only for the three beliefs included in the final model. In conclusion, the validity and re-liability of the Spanish version of the Relationship Belief Inventory (RBI-S) were sufficiently supported in this study.
