Abstract:
Factor analysis and item response theory were used to further validate and refine the Moss Attention Rating Scale (MARS), an observational rating scale of attention-related behavior, in patients with traumatic brain injury (TBI). Participants were rated independently on the MARS over a 3-day period by treating occupational and physical therapists. Exploratory and confirmatory factor analyses revealed 3 correlated factors of disordered attention, interpreted as restlessness/distractibility, initiation, and sustained/consistent attention. Rasch (item response) analysis was used to eliminate redundant items and to fill gaps in item difficulty. Results yielded a new MARS consisting of 22 items that produce 3 factor scores and a total score that can assess different dimensions of disordered attention in acute TBI and monitor change over time and treatment response within these dimensions.
