Development and validation of the Moral Injury Symptom Scale – Clinician Version – Short Form (MISS-CV-SF)

Abstract

Background Moral injury occurs when one witnesses or perpetrates an act that transgresses strongly held moral beliefs and expectations. First documented among active military and veterans, moral injury is increasingly studied in healthcare personnel impacted by the coronavirus pandemic. Measurement of moral injury among this population, particularly nurses, is still in its infancy. Objective To develop the Moral Injury Symptom Scale – Clinician-Short Form and validate it among United States based acute care nurses. Methods The Moral Injury Symptom Scale – Military Version was modified for a healthcare audience. 174 acute care nurses responded to a survey package including the scale and related instruments. Reliability and validity, including convergent and discriminant validities, were assessed, and a cutoff score was calculated using the area under the receiver operating characteristic curve. Results Reliability (Cronbach α = .75) and validity were established and a cutoff score of 41, based on functional impairment caused by moral injury, demonstrated 86.4% sensitivity and 69.6% specificity. Nurses who screened positive for moral injury experienced higher depression, anxiety, work exhaustion, interpersonal disengagement, emotional exhaustion, and depersonalization. Conclusions The Moral Injury Symptom Scale – Clinician Version – Short Form is a valid and reliable instrument with strong psychometric properties that can assess moral injury in acute care nurses, a population at risk due to the challenges of providing care during the pandemic. Appropriate measurement and establishing prevalence should prompt support and intervention from healthcare organizations.
