To assess diagnostic accuracy and test-retest reliability, two forms of a nonword repetition task were administered to 22 preschool children with specific language impairment (SLI) and to 22 age- and gender-matched children with normal language (NL). Results were compared with performance on a digit span task and norm-referenced test scores. Nonword repetition scores provided excellent sensitivity and specificity for discriminating between groups. Scores on both nonword repetition and digit span tasks improved significantly from first to second administrations for both groups, but remained relatively stable at the third administration. The SLI group appeared to benefit more from repetition than the NL group. Acceptable levels of test-retest reliability were achieved for the digit span task, but not for the NL group on the nonword repetition task. These preliminary findings suggest that with further refinement to improve test-retest reliability, nonword repetition holds promise as a diagnostic measure for SLI in preschool children. EDUCATIONAL OBJECTIVES: As a result of this activity, the participant will be able to (1) describe the content and administration of nonword repetition tasks; (2) explain why evidence of test-retest reliability is necessary before a measure may be considered reliable for diagnostic purposes; and (3) accurately compare the sensitivity and specificity of the nonword repetition task utilized in this study to standardized language test scores.
