Use of the Leiter International Performance Scale with adult aphasics

Considered whether the Leiter International Performances Scales (LIPS), a general intelligence test used successfully with Ss age 2-18, can be adapted for use with aphasic adults. Six aphasic adults and 6 matched controls were given the Reitan Indians Screening Test of Aphasia and the LIPS. Results showed that the aphasic sample had total test scores comparable with the control group; however, the aphasic group required approximately 66% more time than the controls to complete the test. It was concluded that further work is merited based on the following results: (1) the test provided a sufficient range of difficulty so that each S errored on at least one-fourth of the test items; (2) the test could be given to the adult aphasics within a feasible time frame; (3) the aphasic adults were able to work with the test materials despite visual defects and hemiparesis of the dominant side; (4) feasible modifications can be made in the test.
