Abstract
The present study examined the psychometric properties of a shortened and simplified version of the Injustice Experience Questionnaire (IEQ). The instructional set of the original IEQ was modified to make it better suited to the context of debilitating health and mental health conditions that do not necessarily arise as a result of injury. The number of items was reduced from 12 to 5, and the response scale was simplified. The Injustice Experiences Questionnaire – Short Form (IEQ-SF) was administered to individuals diagnosed with a chronic musculoskeletal (MSK) condition (N = 88) or major depressive disorder (MDD) (N = 87). The internal consistency of the IEQ-SF was acceptable. The IEQ-SF was significantly correlated with measures of pain severity, depressive symptom severity and disability in both samples. Individuals with MDD scored higher on the IEQ-SF than individuals with MSK. The IEQ-SF was shown to be sensitive to treatment-related reductions in perceived injustice. Preliminary analyses suggest that the IEQ-SF is a reliable and valid measure of disability-related injustice perceptions associated with debilitating health and mental health conditions.
