摘要

Introduction. Behavioral changes often occur after moderate-to-severe traumatic brain injury (TBI) and can lead to poor health, psychosocial functioning, and quality of life. Challenges in evaluating these behaviors often result from the complexity and variability in the way they are conceptualized and defined. We propose and test a conceptual model that is specific to behavioral symptoms after TBI, to serve as a basis for better assessment and treatment. We hypothesized that clusters of individuals, with unique emotional, cognitive, and behavioral characteristics, would emerge that would illustrate this conceptual model. Methods. We conducted model-based cluster analyses in two cohorts, 6-months post-injury (n=79) and >6months post-injury (n=62), of adults with moderate-to-severe TBI to explore the face validity of our conceptual model by evaluating how participants clustered with regard to emotional (Patient Health Questionnaire 9, Positive and Negative Affect Schedule), cognitive (neuropsychological test battery), and frontal behavioral (Frontal Systems Behavior Scale) symptoms. Results. In each cohort, unique clusters of participants emerged that differed significantly with regard to emotional state, cognition, and behavior (ps 6months) demonstrated a more complex pattern of symptoms; the most severe behavioral symptoms occurred in the context of severe emotional symptoms, even in the absence of cognitive impairment. However, problematic behavioral symptoms were also present in the context of severe cognitive impairment, even in the absence of emotional symptoms. Conclusions. Emotional, cognitive, and behavioral characteristics were represented as expected, based on the proposed conceptual model of behavior. This conceptual model provides the basis for evaluating behavioral changes after moderate-to-severe TBI and identifying modifiable targets and relevant subpopulations for behavioral intervention, with the goal of improved evidence-based personalized medicine for this population.
