ABSTRACT
The U.S. military veteran population experiences elevated rates of suicide relative to demographically matched community samples. Understanding suicide risk factors in veterans is therefore of critical importance. Accordingly, the Veterans Health Administration (VHA) has implemented elevated vigilance for suicidal ideation in its health care. One potential risk factor for suicidal ideation or behavior may be attention-deficit/hyperactivity disorder (ADHD), which is frequently characterized by impaired impulse control and experience of intense emotions. To determine whether ADHD, as diagnosed by VHA assessment, may represent an independent or interactive risk factor for suicidal ideation or suicide attempt, we examined potential linkages between VHA-assessed symptomatology of ADHD and suicide attempts or ideation, either with or without the presence of comorbid VHA-assessed psychiatric symptomatology. In a retrospective chart review, we compared severity of clinician-rated suicide risk in 342 veterans (82.5% male) referred to a VHA medical center for ADHD assessment, of whom 198 were diagnosed with ADHD. Contrary to our preregistered hypotheses, there were no main or additive effects of ADHD in terms of increased suicidal ideation, clinician-rated suicide risk or in incidence of lifetime suicide attempt. Motoric impulsivity in neurocognitive testing also showed no relationship with suicide risk or attempts. Rather, consistent with previous literature, presence of a mood disorder or other non-ADHD psychopathology was linked to suicide risk ratings and attempts, irrespective of presence of ADHD symptoms. These data suggest that once comorbid symptomatology such as depression is controlled for, ADHD alone is not associated with elevated suicidal ideation or attempts in veterans.

ABSTRACT
OBJECTIVE: Examine factors associated with recovery from posttraumatic stress disorder (PTSD) and evaluate the role of deployment mild traumatic brain injury (mTBI) in the relationship between PTSD recovery and functional outcomes. METHOD: Post 9/11 combat veterans with lifetime history of PTSD (N = 124, 84.7% male) completed the Mid-Atlantic MIRECC Assessment of Traumatic Brain Injury (MMA-TBI), Salisbury Blast Interview (SBI), Clinician Administered PTSD scale (CAPS-5), cognitive assessment battery, and measures of depression, PTSD symptoms, neurobehavioral symptoms, sleep quality, pain interference, and quality of life. RESULTS: Analyses of variance (ANOVA) results revealed significant differences in most behavioral health outcomes based on PTSD recovery, with participants who have recovered from PTSD showing less severe neurobehavioral and depressive symptoms, better sleep quality, less functional pain interference, and higher quality of life. No differences were found in cognitive functioning between those who have recovered from PTSD and those who have not. History of deployment mTBI did not significantly moderate the relationship between PTSD recovery and most functional and cognitive outcomes with the exception of 2 measures of processing speed. Specifically, among participants with history of deployment mTBI, those who have recovered from PTSD displayed better cognitive functioning than those who have not. Additionally, participants who have not recovered from PTSD had higher levels of blast exposure during military service. CONCLUSIONS: PTSD recovery was associated with better psychological functioning and higher quality of life, but not with objective cognitive functioning. Deployment mTBI history moderated only the relationship between PTSD recovery status and tests of processing speed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
