Chronic Pain, PTSD and Moral Injury in Military Veterans: Suffering and the Compromised Self
Abstract: Veterans with chronic pain may face complex additional challenges, notably the potentially high rate of comorbid post-traumatic stress disorder. Linked to this is the developing concept of moral injury, essentially feelings of guilt and shame associated with transgressing one’s moral beliefs. Work has begun to explore moral injury in the context of psychological trauma, however it has not to date been considered in relation to chronic pain. As the moral injury concept is still developing, this paper explores what is known about the roles of guilt and shame in psychological trauma and chronic pain, and aims to set this in a military context, to begin to understand clinical implications and to make recommendations for further research. A search of the literature reveals that guilt and shame in psychological trauma and chronic pain are not well understood, and research has predominantly focused on these as consequences, rather than as potential contributory elements. Literature is currently separated, focusing either on PTSD or on chronic pain, and we suggest a more integrated approach is required.
Abstract: Disordered eating is a prevalent and relevant health concern that remains understudied among U.S. military veterans. Avoidant/restrictive food intake disorder (ARFID) is a newly recognized feeding and eating disorder characterized by overly restrictive eating due to (a) picky eating, (b) lack of appetite, and (c) fear of aversive consequences related to eating. The Nine-Item ARFID Screen (NIAS) is a recently developed ARFID screening tool with initial validation studies demonstrating psychometric support. However, the psychometric properties of the NIAS have not been investigated in a veteran sample. To advance our understanding of ARFID screening tools that may be appropriate for use in veterans, the present study examined the factor structure of the NIAS using survey data from a large national sample of recently separated veterans (N = 1,486). Measurement invariance across key subgroups was tested in addition to exploring differential associations between the NIAS and related constructs. Results suggested that a three-factor model provided an excellent fit of the data and demonstrated scalar invariance across self-identified men and women, race and ethnicity, and sexual and gender minority (SGM) identity. Some subgroups had higher latent means on the picky eating (women, SGM, non-Hispanic Black), appetite (women, SGM), and fear (women) factors. The NIAS had some overlap with another measure of disordered eating and was moderately correlated with psychosocial impairment and mental health. Overall, the NIAS may be a useful screening tool for ARFID in veterans, given support for the three proposed subscales and equivalence across diverse identities.
