[Psychometric properties of the Interpersonal Reactivity Index in Spanish child and adolescent population].

This article analyses the dimensions of the Interpersonal Reactivity Index (IRI; Davis, 1980). The sample comprised 721 Spanish participants between 9 and 16 years old. Diverse exploratory factor analyses were conducted as the basis for the final confirmatory factor analysis, through self-report. The results supported a structure with 5 first-order main factors (Intellectual empathy, Positive emotional empathy, Disorganized emotional empathy, Virtual empathy, and Impassiveness), where the two first factors are nested in a second-order dimension: "Considerate Social Style". The psychometric characteristics of the instrument were adequate. The proposed model is a new alternative to conceptualize the factor structure of empathy.
