Abstract
The aim of this study was to evaluate the reliability and validity of the Spanish version of the Transgression-Related Interpersonal Motivations Inventory (TRIM-18) for measuring forgiveness in couple relationships in a Chilean context. The TRIM-18 is a self-report questionnaire that measures the respondent’s motivation for avoidance, revenge, and benevolence when faced with a relational transgression. In order to examine its psychometric properties, 3 independent non-probabilistic samples were evaluated: 2 composed of university students ( N = 181 and 394) and 1 from the general community ( N = 552), all from the city of Antofagasta, Chile. The results obtained make it possible to conclude that the TRIM-18 is a reliable and valid instrument for use in a Chilean context, given its adequate internal consistency indexes and good fit to a three-dimensional factorial structure. Moreover, associations were found with constructs theoretically related constructs to forgiveness, such as a global self-report of forgiveness, relational satisfaction, and socioemotional adjustment.
