Military veterans can experience a lot of challenges during their transition to civilian life. Previous research has found that veterans are at high risk of gambling harm. This may impact their risk of suicide. The purpose of this study was to examine the links between gambling problems and suicidality among recently transitioned veterans of the Australian Defence Force (ADF). A total of 3,511 responses from ADF veterans who stopped full-time regular military service between 2010 and 2014 were included in the analysis. Veterans with at-risk gambling and problem gambling were more likely to report suicidal ideation and suicide planning or attempts. After taking into account depressive symptoms, gambling problems no longer predicted suicidality.
