Clinical Psychological Testing: A Review of Premises, Practices and Promises

Summary

Widespread divergencies of opinion exist over the usefulness, the nature, the purpose, and the scientific status of clinical psychological testing. This paper seeks to order these problems in historical and philosophical perspective. Largely different values and orientations have been contributed by traditional American academic psychology, by clinical psychology, and by psychiatry. Academic psychologists advocate a rigorous scientific basis (logical positivism) for testing, which the clinician tends to find overly confining and antagonistic to his humanistic, individual centered, service orientation; while psychiatrists tend to differ greatly among themselves in their understanding of psychological testing and hence exert no uniform influence on the practice. The current trend emphasizes greater sophistication in the academic approach to testing, with advances in empiricism and computer-aided manipulation of data, while the more clinically oriented psychologists seek to strengthen their theoretical position and to demonstrate the effectiveness of their methods through studies of clinical judgment. At the same time basic methodological research to support the “clinical position” is yet too sparse. It is proposed that both academic and clinical approaches have a significant contribution to make to clinical psychological testing. Ultimately the design of psychological tests and the evaluation of their usefulness rests upon what we conceive psychological science to be, and we need to remind ourselves, in this regard, that the conception of science is subject to change.
