Abstract The Experiences in Close Relationships (Brennan et al, Attachment theory and close relationships, 1998) questionnaire is one of the most widely used measures of adult romantic attachment. Despite the advantages of the ECR, the length of this measure may discourage its use in clinical and research contexts. Consequently, the goal of this study was to develop a brief Spanish version of the ECR questionnaire and to examine its psychometric properties when administered to six different Spanish-speaking samples from Chile. Confirmatory factor analyses replicated the twodimensional structure of the ECR and its invariance across gender. Results also supported the reliability and concurrent validity of our brief Spanish version of the ECR (i.e., Spanish ECR-12), by its association with measures of emotion regulation, dyadic empathy, psychological distress and well-being, and relationship satisfaction. The Spanish ECR-12 can be used by researchers and clinical professionals as an abridged measure of adult attachment.

In recent years, empathy became part of the set of variables that allow us to gain insight about a variety of aspects about how couples handle their relationships. This makes it necessary to make use of properly validated instruments to evaluate this construct. The goal of this study was to evaluate the psychometric properties of the Chilean version of Interpersonal Reactivity Index for Couples (IRIC-C) in two independent samples. One was a sample of university students (N = 612) and the other was taken from the general population (N = 766) of the city of Antofagasta, Chile. The internal consistency indexes as appropriate for the perspective taking scale, but they fell below the optimal level for the empathic concern scale. A confirmatory factor analysis corroborated the two-dimensional structure of the instrument and the invariance across gender. We also present evidence of discriminant validity and discuss the implications, contributions and limitations of the results obtained.

En los últimos años, la empatía se ha incorporado como una variable que permite comprender diversos aspectos del funcionamiento en las relaciones de pareja, lo cual hace necesario contar con instrumentos validados que permitan evaluar este constructo. El presente estudio tuvo como objetivo evaluar las propiedades psicométricas de la versión chilena del Indice de Reactividad Interpersonal para Parejas (IRIC-C) en dos muestras independientes: una de estudiantes universitarios (N = 612) y otra de población general (N = 766) de la ciudad de Antofagasta, Chile. Los índices de consistencia interna fueron adecuados para la escala de toma de perspectiva, sin embargo, no alcanzaron los niveles óptimos para la preocupación empática. El análisis factorial confirmatorio corroboró la estructura bidimensional del instrumento y la invarianza métrica entre hombres y mujeres. Asimismo, se presenta evidencia acerca de la validez discriminante del instrumento. Los resultados son discutidos en términos de sus implicancias, aportes y limitaciones.
