OBJECTIVE: To determine the role of cognitive testing in predicting age-appropriate audiometric responses among children aged 30 to 42 months.

STUDY DESIGN: Prospective.

SETTING: Tertiary care audiology clinic.

SUBJECTS AND METHODS: Subjects included primary English-speaking children aged 30 to 42 months. A certified pediatric audiologist performed the cognitive aspect of the Developmental Assessment of Young Children-Second Edition (DAYC-2). A second, blinded audiologist performed age-appropriate audiometry. The raw, age-equivalent, percentile, and standard DAYC-2 scores were compared by agreement between speech reception threshold (SRT) and pure tone average (PTA). Optimal DAYC-2 thresholds were also calculated for prediction of SRT-PTA agreement and assessed for sensitivity, specificity, and positive and negative predictive values. P < .05 was considered significant.

RESULTS: Complete data were obtained from 37 children. The mean age was 34.9 months (95% CI, 33.5-36.2), and 15 (41%) were female. Among the 37 children, 24 (65%) and 13 (35%) underwent visual reinforcement audiometry and conditioned play audiometry, respectively. SRT-PTA agreement was seen in 32 (87%) tests. Mean DAYC-2 raw score grouped by SRT-PTA agreement was 39.4 versus 33.4 for nonagreement (2.8-9.3, P < .001). The mean age-equivalent score grouped by SRT-PTA agreement was 29.6 versus 23.0 for nonagreement (2.7-10.6, P = .002). Optimal cut points based on DAYC-2 scores achieved moderate overall prediction performance (area under the curve, 0.73-0.77) with a positive predictive value of 100%.

CONCLUSION: The DAYC-2 is a useful screen to identify children likely to complete an age-appropriate audiogram.
