Abstract
Introducción: La escala Transgression-Related Interpersonal Motivations
(TRIM-18) es un instrumento diseñado para evaluar perdón específico
compuesto por tres subescalas: evitación, venganza y benevolencia. En el
presente estudio se examina la dimensionalidad de la versión española del
TRIM-18 (TRIM-18-S). Se presentan evidencias de fiabilidad y de validez
de constructo de la interpretación de las puntuaciones. Método: Un total de
943 sujetos completaron el TRIM-18-S. Una submuestra de 94 participan-
tes completaron la escala otra vez dos semanas después para el cálculo de la
estabilidad temporal, y 277 participantes completaron medidas adicionales
de empatía, ira e información relacionada con el tipo de ofensor para el
cálculo de la validez de constructo. Resultados: El TRIM-18-S mostró buenas
propiedades psicométricas. El análisis factorial confirmatorio reveló una es-
tructura tridimensional. Los valores del alfa de Cronbach variaron entre .80
y .90. Los valores obtenidos para la fiabilidad test-retest variaron entre.74 y
.84. Se hallaron evidencias de validez de constructo a partir de las correla-
ciones con el ítem único de medida de perdón y con empatía, ira, cercanía
con el ofensor y tipo de relación. Conclusiones: La escala presenta propieda-
des psicométricas adecuadas para su uso en población española
Introduction: The Transgression-Related Interpersonal Motiva- tions Inventory (TRIM-18) is an instrument that assesses episodic for- giveness composed of three subscales: avoidance, revenge and benevo- lence. In the present study we examined the dimensionality of the Spanish version of the TRIM-18 (TRIM-18-S). We provided evidences of estimated reliability and construct validity of the interpretation of the scores. Method: A total of 943 participants completed the TRIM-18-S. A subset of 94 par- ticipants completed the measure again to allow computation of two-week estimated temporal stability, and 277 participants completed additional measures of empathy, anger, and information regarding the relation with the offender to allow computations supporting construct validity. Results: The TRIM-18-S showed good psychometric properties. Confirmatory fac- tor analysis revealed a three-factor structure. Alphas ranged from .80 to .90. Two week estimated test-retest correlations ranged from .74 to .84. Con- struct validity was supported by correlations with a single-item measuring forgiveness and with empathy, state anger, and closeness and type of rela- tionship. Conclusions: The scale presents adequate psychometric properties for its potential use in Spanish population.
