OBJECTIVE: To examine the relationship between executive dysfunction, as a
multidimensional construct (ie, decision-making, impulsivity, aggression, concept
formation), and suicide attempt (SA) history in a high-risk sample of veterans
with moderate to severe traumatic brain injury (TBI). DESIGN: Observational, 2x2
factorial design. To estimate group differences, linear regression was used to
model the primary and secondary outcomes of interest as a function of history of
SA, TBI, and the interaction between the 2 variables. Additionally, to determine
the pattern of performance over the course of the Iowa Gambling Test (IGT),
scores were modeled across the 5 IGT blocks by using a varying-coefficient model.
SETTING: Veterans Health Administration. PARTICIPANTS: Veterans (N=133; no SA/no
TBI, n=48; no SA/yes TBI, n=51; yes SA/no TBI, n=12; yes SA/yes TBI, n=22)
completed the study measures. INTERVENTIONS: Not applicable. MAIN OUTCOME
MEASURES: IGT, Immediate and Delayed Memory Test, State-Trait Anger Expression
Inventory-2, Wisconsin Card Sorting Test. RESULTS: All groups demonstrated
learning over the course of the IGT, except for veterans with a history of both
SA and TBI. No group differences were identified on other measures of executive
functioning. CONCLUSIONS: These findings highlight the potential, unique
decision-making challenges faced by veterans with a history of TBI and SA.
Specialized interventions focused on overall distress reduction and means
restriction may be required to prevent future self-directed violence.
