Perceived injustice in multiple sclerosis: An initial, exploratory study.

Purpose/objective: The current study represents an initial examination of condition-related perceived injustice (PI) in multiple sclerosis (MS) by examining (a) the structural validity and reliability of the Injustice Experience Questionnaire (IEQ) scores and (b) the associations between IEQ scores and scores from measures of anger, pain, depression, anxiety, fatigue, disability, health-related quality of life (HRQOL), physical activity, and sedentary behavior. Research Method/Design: Persons with MS were recruited through the distribution of letters to a random sample of 1,000 persons from the North American Research Committee on MS registry. Participants who completed the IEQ (N = 139) were included in this analysis.
