Health and Wellbeing Study of Serving and ex-Serving UK Armed Forces Personnel: Phase 4
Abstract: The study has been running since 2003 with the aim of investigating the impact of deployment to Iraq (Operation TELIC) and Afghanistan (Operation HERRICK) on the health and wellbeing of serving and ex-serving personnel.
Data have been collected over three previous phases - Phase 1 (2004/06), Phase 2 (2007/09), and Phase 3 (2014/16), with the most recent phase taking place over 2022/23. In addition to examining key mental health outcomes such as CMD, probable PTSD and alcohol misuse, this phase also collected new data on additional topics relevant to UK serving and ex-serving personnel including complex PTSD (C-PTSD), loneliness and caring responsibilities.
For Phase 4 (2022/23), we followed up participants who took part in the previous phase in 2014/16. 4104 participants completed the survey. 69% of the sample had deployed to Iraq and/or Afghanistan and 72% had left service.
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.
