The clinical utility of the Arthur Adaptation of the Leiter International Performance Scale (LIPS) was investigated in a sample of 100 children with either developmental or acquired aphasia. Test-retest reliability data and concurrent validity data with the Peabody Picture Vocabulary Test (PPVT) were obtained. Group and individual performance on the LIPS over a period of six months was highly consistent. The reliability coefficient was 0.916, which compares favorably with the reported reliability of most commonly used intelligence tests. Although a moderately significant correlation was obtained between PPVT and LIPS IQs, group performance on the PPVT was substantially lower than that on the LIPS. The LIPS provided higher IQs in 75 of the 100 subjects, suggesting that the LIPS is a more adequate measure of intellectual potential and the PPVT performance reflects the extent of the language disability. The LIPS appears adequately reliable for use with aphasic children. The utility of concurrent use of the LIPS and PPVT is discussed.
