Linking Neurobehavioral Symptoms to Productive Activities in Post-9/11 Veterans: A Correlational Analysis Using TVMI...

Area of Science:

• Neuroscience
• Military Medicine
• Public Health

Background:

• Military veterans face long-term neurobehavioral symptoms impacting their transition to civilian life.
• These symptoms can hinder participation in productive activities, affecting overall well-being and economic stability.

Purpose of the Study:

• To examine the association between injury-related neurobehavioral symptoms and engagement in paid and unpaid productive activities among post-9/11 veterans.
• To identify specific symptoms that most significantly impact veteran employment post-service.

Main Methods:

• Secondary cross-sectional analysis of the Veterans Metrics Initiative (TVMI) Study data.
• Multinomial logistic regression used to assess the relationship between self-reported vestibular, somatosensory, cognitive, and affective symptoms and productive activity status.
• Models adjusted for pre-military TBI, deployment TBI, demographics, and post-traumatic stress disorder (PTSD) screening.

Main Results:

• Vestibular symptoms were linked to a lower likelihood of engaging in paid labor only and both paid and unpaid labor.
• Cognitive symptoms were associated with a reduced likelihood of paid labor only.
• Post-traumatic stress disorder (PTSD) was a strong predictor, with positive screens reducing likelihood of paid labor engagement by 53% and combined labor by 37%.

Conclusions:

• Vestibular and cognitive symptoms are significantly related to decreased engagement in productive activities, especially paid employment, for veterans post-service.
• Post-traumatic stress disorder (PTSD) also strongly predicts reduced participation in paid work.
• Treatment and management of these neurobehavioral symptoms may improve veteran participation in productive activities.
