Abstract
Narratives generated by 32 school-aged children, 16 with prenatal alcohol exposure, were analyzed to identify discourse behaviors associated with CNS damage. Children were ranked on a 4-point scale for evidence of CNS damage (unlikely, possible, probable, definite). CNS-rank was correlated (Kendall’s tau b, p< 0.05) with three productivity measures (Number of Different Words, Total Words, Total Utterances) and several measures of cohesion (number of personal pronouns/cohesive pronoun ties, number of indefinite nominal introductions-INI, rate of Nominal Reference Errors—rNRE). One-way ANOVA revealed significant effects of CNS-rank on the number of INI (F=5.996, p= 0.003), and rNRE (F= 15.834, p= 0.0001). Children having definite CNS damage produced fewer INI with higher rNRE than those for whom CNS damage was unlikely/possible. Children with probable CNS damage had higher rNRE than those unlikely to have CNS damage (all contrasts Scheffe, p<0.05). The accuracy with which rNRE identified probable/definite CNS damage (sensitivity 88%, specificity 92%) supports further development of narrative analysis tools for identify underlying CNS impairment in complex clinical populations.
