BACKGROUND: Although central @entity1650 (CAPD) test battery performance has been examined in adults with @entity149 (CANS), similar data on @entity1 being referred for CAPD evaluations are sparse. PURPOSE: This study characterizes CAPD test battery performance in @entity1 using tests commonly administered to diagnose the disorder. Specifically, this study describes failure rates for various test combinations, relationships between CAPD tests used in the battery, and the influence of cognitive function on CAPD test performance and CAPD diagnosis. A comparison is also made between the performance of @entity1 with CAPD and data from @entity1 with @entity16 of the CANS. RESEARCH DESIGN: A retrospective study. STUDY SAMPLE: Fifty-six pediatric @entity1 were referred for CAPD testing. DATA COLLECTION AND ANALYSIS: @entity1 were administered four CAPD tests, including frequency patterns (FP), low-pass filtered speech (LPFS), @entity433 ( @entity433 ), and competing sentences (CS). In addition, they were given the Wechsler Intelligence Scale for @entity1 (WISC). Descriptive analyses examined the failure rates of various test combinations, as well as how often @entity1 with CAPD failed certain combinations when compared with adults with CANS lesions. A principal components analysis was performed to examine interrelationships between tests. Correlations and regressions were conducted to determine the relationship between CAPD test performance and the WISC. RESULTS: Results showed that the FP and LPFS tests were most commonly failed by @entity1 with CAPD. Two-test combinations that included one or both of these two tests and excluded @entity433 tended to be failed more often. Including the @entity433 and CS test in a battery benefited specificity. Tests thought to measure interhemispheric transfer tended to be correlated. Compared with adult @entity1 with @entity16 , @entity1 with CAPD tended to fail LPFS more frequently and @entity433 less frequently. Both groups failed FP with relatively equal frequency. CONCLUSIONS: The two-test combination that showed the highest failure rate for @entity1 with CAPD was LPFS-FP. Comparison with adults with CANS lesions, however, suggests that the mechanisms underlying LPFS performance in @entity1 need to be better understood. The two-test combination that showed the next highest failure rates among @entity1 with CAPD and did not include LPFS was CS-FP. If it is desirable to use a dichotic measure that has a lower linguistic load than CS then @entity433 can be substituted for CS despite the slightly lower failure rate of the @entity7944 .
