This study examined the relation between posttraumatic stress disorder (PTSD) and suicidal ideation among U. S. military veterans deployed during Operation Enduring Freedom and/or Operation Iraqi Freedom. ⋯ PTSD-diagnosed participants with co-occurring MDD or AUD were not significantly more likely to endorse suicidal ideation than PTSD-diagnosed participants without such comorbidity. The 'emotional numbing' cluster of PTSD symptoms and the 'cognitive-affective' cluster of MDD symptoms were uniquely associated with suicidal ideation.
