Evidências de validade da versão portuguesa do Índice de Reatividade Interpessoal para Casais

The main objective of this study was to translate and adapt the Interpersonal Reactivity Index for Couples (IRIC) to Portuguese, and analyze the psychometric properties of the Portuguese version. This instrument that assesses empathy in couples, resulted from the adaptation of one of the most widely used empathy scales - Davis's Interpersonal Reactivity Index - for the context of intimate relationships. The IRIC assesses dimensions of cognitive (perspective taking) and emotional (empathic concern) empathy, both essential for stable and satisfactory marital relationships. The original scale was translated to Portuguese and administered to 148 participants involved in an intimate relationship with a minimum duration of one year. Most of the participants were women, with a mean age of 27 years old. Our results revealed the Portuguese version has a factorial structure similar to the original version, adequate internal consistency values (Cronbach's α=.82), and good external validity with a scale of dyadic adjustment.
