Trauma Related Guilt Inventory – psychometric properties of the Polish adaptation (TRGI-PL)

Summary
Aim. Although various aspects of guilt are frequent problems of patients suffering from PTSD, they have been included into the diagnostic criteria for PTSD just in the present version DSM-5. Kubany proposed a cognitive conceptualization of guilt in PTSD followed by development of the Trauma Related Guilt Inventory (TRGI). The aim of the paper is to present psychometric properties of the Polish version of the inventory – the TRGI-PL.
Methods. A Polish adaptation of the Trauma-Related Guilt Inventory was applied to a sample of 280 motor vehicle (MVA) participants (147 females, 133 males of age from 18 to 80 (M=34,93, SD=13,71) within 1-24 months after a MVA (M=10,18, SD=6,23). Validation of the Polish version was done by analyzing the internal structure of the instrument and comparing the emotional and cognitive aspects of guilt assessed by the TRGI with PTSD symptoms, post-traumatic cognitions and responsibility for MVA and subjective agreement with the judgment.
Results. The model with four latent factors: Distress, Hindsight-Bias/Responsibility, Wrongdoing and Insufficient Justification scales showed acceptable fit (Satorra-Bentler chi2=518,62, df=203, p<0,01, RMSEA=0,079, CFI=0,96, GFI=0,97), what confirms the four-factor structure of guilt, obtained in the studies on original TRGI version. Reliability coefficients are similar to original version. Correlations with other PTSD measures showed satisfactory convergent and discriminative validity.
Conclusions. The Polish adaptation of the Trauma-Related Guilt Inventory is a reliable and valid tool for assessing guilt as a multidimensional phenomenon, comprising emotional and several cognitive characteristics, in trauma survivors.
