Background Substance use disorders (SUDs), which encompass alcohol and drug use disorders (AUDs, DUDs), constitute a major public health challenge among US veterans. SUDs are among the most common and costly of all health conditions among veterans. Objectives This study sought to examine the epidemiology of SUDs among US veterans, compare the prevalence of SUDs in studies using diagnostic and administrative criteria assessment methods, and summarize trends in the prevalence of SUDs reported in studies sampling US veterans over time. Methods Comprehensive electronic database searches were conducted. A total of 3,490 studies were identified. We analyzed studies sampling US veterans and reporting prevalence, distribution, and examining AUDs and DUDs. Results Of the studies identified, 72 met inclusion criteria. The studies were published between 1995 and 2013. Studies using diagnostic criteria reported higher prevalence of AUDs (32% vs. 10%) and DUDs (20% vs. 5%) than administrative criteria, respectively. Regardless of assessment method, both the lifetime and past year prevalence of AUDs in studies sampling US veterans has declined gradually over time. Conclusion The prevalence of SUDs reported in studies sampling US veterans are affected by assessment method. Given the significant public health problems of SUDs among US veterans, improved guidelines for clinical screening using validated diagnostic criteria to assess AUDs and DUDs in US veteran populations are needed. Scientific Significance These findings may inform VA and other healthcare systems in prevention, diagnosis, and intervention for SUDs among US veterans.

Mental health crisis is on the rise for young people, while suicide is the third leading cause of death among young people worldwide. Theatre-based approaches have been used to encourage social connection and emotional support. This scoping review seeks to map the current landscape of theatre-based suicide prevention programmes for young people, explore programme implementations and youth involvement and examine how evidence is shared. Twelve articles detailed theatre-based suicide prevention programmes delivered to youth. Practitioners and researchers have an optimistic view of the positive impact of immersive experiences created by theatre-based approaches for reducing suicide risk. To optimize theatre-based programmes to promote mental well-being among youth, further research is needed to evaluate effectiveness at promoting help-seeking and reducing social stigma related to mental health. Interdisciplinary teams can collaborate on findings, innovate solutions to challenges and share best practices in this field.
