ObjectiveTo determine whether the Short-Term Executive Plus (STEP) cognitive rehabilitation program improves executive dysfunction after traumatic brain injury (TBI).DesignRandomized, waitlist controlled trial with minimization and blinded outcome assessment.SettingCommunity.ParticipantsParticipants with TBI and executive dysfunction (N=98; TBI severity 50% moderate/severe; mean time since injury ± SD, 12±14y; mean age ± SD, 45±14y; 62% women; 76% white).InterventionSTEP program: 12 weeks (9h/wk) of group training in problem solving and emotional regulation and individual sessions of attention and compensatory strategies training.Main Outcome MeasuresFactor analysis was used to create a composite executive function measure using the Problem Solving Inventory, Frontal Systems Behavior Scale, Behavioral Assessment of the Dysexecutive Syndrome, and Self-Awareness of Deficits Interview. Emotional regulation was assessed with the Difficulties in Emotion Regulation Scale. The primary attention measure was the Attention Rating and Monitoring Scale. Secondary measures included neuropsychological measures of executive function, attention, and memory and measures of affective distress, self-efficacy, social participation, and quality of life.ResultsIntention-to-treat mixed-effects analyses revealed significant treatment effects for the composite executive function measure (P=.008) and the Frontal Systems Behavior Scale (P=.049) and Problem Solving Inventory (P=.016). We found no between-group differences on the neuropsychological measures or on measures of attention, emotional regulation, self-awareness, affective distress, self-efficacy, participation, or quality of life.ConclusionsThe STEP program is efficacious in improving self-reported post-TBI executive function and problem solving. Further research is needed to identify the roles of the different components of the intervention and its effectiveness with different TBI populations.Copyright © 2014 American Congress of Rehabilitation Medicine.
