Introduction. Suicide is a leading cause of death in the United States and considered a major public health problem (CDC, 2024 (CDC, 2024)). US Army soldiers are at greater risk for suicide compared to the civilian population. US Army active duty population, suicide rates surpassed civilian suicide rates in 2008 and have continued to climb annually (Reimann & Mazuchowski, 2018). Background. Transdiagnostic theories for suicide- Interpersonal Psychological Theory of Suicide (IPS) and “Psychache”; and adjacent theories such as Military Transition Theory (MTT), have shown stronger predictive power compared to diagnostic theories and frameworks when studying suicidal thoughts and behaviors (STBs) in other populations (Dalgleish et al., 2020; Fusar-Poli et al., 2019; Karnick et al., 2022; Toma et al., 2023). US Army Commanders (CDRs) and Behavioral Health Officers (BHOs; Social Workers and Psychologists), are responsible for the psychological health and welfare of soldiers who experience suicide-related incidents but little is known about CDRs’ and BHOs’ views on these theories. Research Purpose: Determine if former/current CDRs and BHOs believe they observe the presence of transdiagnostic theory constructs in their soldiers who have experienced suicide-related incidents. Materials and Methods. Purposive, convenience, and snowball sampling was used to recruit participants via email. All participants commissioned in 1993 or after, previously or currently serves as a CDR or BHO, and were directly responsible for a soldier with a reported suicide-related incident. Eligible participants completed the 20-item study survey (eighteen close-ended questions, two open-ended questions). Officers nominated a soldier with reported suicide-related incident and reported on context factors, construct endorsement, and rating importance of theory constructs gathered. Chi-square and independent-samples t-tests were used to examine differences between CDRs and BHOs. Thematic analysis for initial, developed, and final mapping were performed using the Braun and Clarke, 2006 qualitative analysis framework. Results. Participants (N= 98) included 48 US Army CDRs (M age: 41.36 (8.8); 76.74% male) and 50 BHOs (M age: 36.41 (7.9), 48.89% male). CDRs and BHOs reported similar observance of theory constructs except that BHOs endorsed more psychache [χ² (2, 97)= 15.48, p < .01] and more perceived burdensomeness [t(75)= 2.34, p <0.05] than CDRs. Stigma in military culture towards seeking BH care was the most important barrier identified for soldiers experiencing suicidality. Fear of negative career impacts and unwillingness to admit to personal problems, particularly marital and family problems, were noted as significant barriers to care; as was, paradoxically, insufficient hours and long waiting lists to obtain care. Engaged peers, leadership, and family who helped soldiers receive help or communicating concerns for the soldier’s safety were the leading facilitators for BH care. Conclusions. Quantitatively, officers appear to endorse constructs and largely consider them important at the time of their soldier’s incident. Qualitatively, we speculated and aligned barriers to BH care with significant findings for triangulation of statistically significant findings and contextualization. Limitations: the sample size of CDRs and BHOs was too small to generalize findings. Recommendations. Future research in the utility of transdiagnostic theories mapped on to suicide-related incidents in the US Army is needed.
