| Abstract: | A general methodology designated the isographic approach, which searches for similarities of personality profiles among individual persons and similarities of single method profiles within an individual person, is differentiated from traditional nomothetic and idiographic methodologies, all of which are interrelated. The review of methods of profile analysis includes single variable and multivariate differentiation of groups, but focuses on Q correlation, generalized distance function, computer-programmed actuarial analyses of profiles, and clustering techniques. Selected research studies published within the past 15 years in the United States and in other countries, in both clinical and nonclinical areas, and probable directions for future research are discussed. |
