Abstract

This study examined the utility of story “goodness,” a measure of organization and completeness in 46 non-brain-injured adults and 171 adults with traumatic brain injury (TBI). Story goodness was quantified using a two-coordinate (story grammar & completeness) grid system. It was hypothesized that the story goodness index would discriminate performance between groups and identify performance subgroups. Results indicated that participants’ scores clustered differentially across quadrants between groups and discriminated groups into four distinct categories of story “goodness.” Findings suggest that story goodness is a sensitive and clinically useful measure for examining the discourse of individuals with TBI.
