IEQ IN TRAUMA 2
AbstractPurpose/Objective: A recent study by Trost et al. (2015) investigated the influence of perceived injustice-reflecting appraisals of the severity and irreparability of loss following injury, blame, and unfairness-on physical and psychological outcomes in a sample of patients 12 months after sustaining traumatic injury. This brief report examines the psychometric properties of the Injustice Experiences Questionnaire (IEQ) using the previous sample from Trost et al. (2015) with added trauma patients (total N = 206).Research Method/Design: Primary analyses included confirmatory and exploratory factor analyses to validate the measurement model of the IEQ in patients 12-months after traumatic injury. Reliability analyses were conducted and construct validity was assessed by examining associations between the IEQ and other pain-related, psychological, and health-related outcome variables of interest.
Results:Results replicated both one-and two-factor structures from past research, with a high factor correlation in CFA analyses and cross-loadings in EFA analyses. Item characteristics analysis demonstrated overall strong internal consistency ( = .95). In addition, significant associations with psychosocial variables provide further support for the utility of measuring injustice perception using the IEQ in a trauma sample.
