The Development of More Efficient Measures for Evaluating Language Impairments in Aphasic Patients.
Phillips, Phyllis P.; Halpin, Gerald
Because it generally took over an hour to administer the Porch Index of Communicative Ability (PICA), a shorter but comparable version of the test was developed. The original test was designed to quantify aphasic patients' ability level on common communicative tasks and consisted of 18 ten-item subtests. Each item resulted in a proficiency rating, ranging from one to sixteen. Two shortened versions of PICA were developed, containing five items selected from each of the original eighteen subtests; these new tests were one-half as long. Subjects were 50 adults (aged 26-78) whose language handicaps were associated with cerebrovascular accident or trauma. Both the original PICA and a new short-form test were administered. Reliability of all test forms was computed, as well as the intercorrelation of short-form scores with various subtest, modality, and overall scores of the original PICA. Results showed that indices of central tendency and variability were virtually equal on both short forms and the long form across all subtests, modalities, and overall score. Test reliability, means, and standard deviations of all forms were also highly similar. Thus, use of the short forms was supported. (Problems associated with particular PICA items are briefly described). (GDC)
