Inventario Texas Revisado de Duelo (ITRD): Adaptación al castellano, fiabilidad y validez

Abstract

Objectives. To adapt into Spanish the Texas Revised Inventory of Grief (TRIG) of Faschinbaguer et al (1977, 1981) and to examine its reliability and validity. Design. Two stages: a) cross-culture adaptation of a questionnaire, and b) cross-sectional study of reliability and validity. Setting. Primary care teams in Vizcaya, north of Spain. Participants. 118 people who had been widowed between 3 months and 3 years before the study. Main measurements and results. Cross-culture adaptation: the TRIG was translated from American English, then back-translated and finally compared with the version in American Spanish by Grabowski & Frantz (1993). Reliability: the Cronbach's alpha coefficients (internal consistency) of the 2 TRIG scales were 0.75 and 0.86. Factorial validity: all items except one threw saturation >0.40 on the 2 factors extracted from the varimax rotation. Validity by hypothesis: the TRIG scales showed differences (P
