Abstract

Background: This study examined the utility of story "goodness", a measure of organisation and completeness, in quantifying narrative discourse deficits following traumatic brain injury (TBI). In an initial study, the story goodness measure demonstrated sensitivity and reliability in distinguishing individuals who had TBI from those who were non-brain-injured. Aims: The purpose of the current study was to validate previous findings of the story goodness index, specifically in discriminating performance between groups and identifying performance subgroups, in a larger sample of participants with TBI. Methods & Procedures: A total of 46 non-brain-injured adults and 171 adults with TBI participated. Story retellings were analysed for story grammar and story completeness. The two discourse scores were then plotted as coordinates, which allowed for quantification of story goodness. Statistical analyses included a multivariate analysis of variance and calculation of Pearson correlation coefficients for the discourse measures. Outcomes & Results: Results indicated that participants' scores clustered differentially across quadrants between groups and discriminated groups into four distinct categories of story "goodness". Conclusions: Findings paralleled those found in the initial study, suggesting that story goodness is a sensitive measure for examining the discourse of individuals with TBI. The story goodness has potential clinical utility and may have implications for investigation of discourse impairments in other clinical populations and treatment of discourse deficits.
