Abstract

The study investigated the item-level psychometrics of the Social Communication (SC) construct, one of six constructs that comprise the Computer Adaptive Measure of Functional Cognition for Traumatic Brain Injury (TBI) (CAMFC-TBI). Sixty-nine individuals with TBI (outpatients and 1-year post injury) and 68 caregivers participated. Rasch analysis demonstrated that the SC had sound psychometrics for both groups. Items conformed to the theoretical difficulty hierarchy. Person reliability (comparable to Cronbach’s alpha) was high. Respondents were separated into at least 3 significantly different ability levels. Differential item functioning showed no statistically significant differences between patients and caregivers. These results are promising for inclusion of the SC items in the CAMFC-TBI.
