Adaptación al español del Differentiation of Self Inventory-Revised (DSI-R)

This study introduces the Spanish Differentiation of Self Inventory(S-DSI) version, a 26 item measure, consisting of 2 subscales—Emotional Reactivity and Emotional Cutoff—focusing on adults (ages 25+) and their significant relationships, including current relations with family of origin.Translation of DSI into Spanish was conducted using a back translation method, with two independent teams for translation into Spanish and back-translation into English. A sample of 1047 adult men and women (living in Spain, native Spanish speakers) completed the Spanish-DSI scale and a socio-demographic questionnaire. Exploratory factor analysis was conducted on a randomly selected half of the sample, and results yielded a two subscalesolution that closely conformed with the original DSI’s Emotional Reactivity and Emotional Cutoff scales. Results of a confirmatory factor analysis cross-validated the measure’s factor structure in the remaining sample. Implications for cross-cultural research and culturally-informed study of Bowen theory in Spanish populations are further discussed.
