Objective : To assess the convergent and divergent validity of the Behavioral Assessment Screening Tool (BAST) among adults with chronic TBI.
Design : Cross-sectional analysis
Setting : Community
Participants (or Animals, Specimens, Cadavers) : Community dwelling adults with a >6 month history of complicated mild to severe TBI (n=110).
Interventions : Not applicable
Main Outcome Measure(s) : BAST1,2 subscales for Negative Affect, Substance Abuse, Executive Function, Fatigue, Impulsivity, and Maladaptive Coping; Patient Health Questionnaire-9 (PHQ-9); General Anxiety Disorder-7 (GAD-7); Frontal Systems Behavioral Scale (FrSBe); Aggression Questionnaire (AQ); Coping Inventory in Stressful Situations (CISS); Positive and Negative Affect Schedule (PANAS); Modified Fatigue Impact Scale (MFIS); and Mayo-Portland Adaptability Inventory (MPAI).
Results : We found strong correlations (|r|=.649-.828, p
Conclusions : The BAST subscales correlated or did not correlate as expected with previously established measures of similar or different constructs. This supports the BAST’s validity for monitoring and distinguishing common symptoms among adults with chronic TBI.
