Scaling clinical judgments of symptom pathology by means of the psychophysiological method of magnitude estimation . Summing scores across heterogeneous symptom items without consideration of their differing psychopathological significance has been criticized as producing an inadequate picture of an individual 's clinical status . The purpose of this study was to derive symptom item weights representing clinically judged seriousness of each symptom through the application of Steven 's psychophysical method of magnitude estimation . A nationwide sample of 129 clinicians rated the pathological significance of 221 symptom items in a design such that every rater rated 121 items , 21 of which were rated by all raters and 100 of which were rated only by the A or B subgroup to which each rater was randomly assigned . Each item was rated as to the seriousness of the pathology it would represent if manifested by either a boy child , girl child , boy adolescent , or girl adolescent , with one-fourth of the raters assigned to each condition . The results of 211 two-way analyses of variance revealed that age and age and sex in interaction , but not sex alone , significantly influenced the clinical ratings . The resulting magnitude estimation ratings of symptom pathology ranged from 1.0 to 9.9 . They were demonstrated to have satisfactoy reliability and convergent validity and to have the psychophysical characteristics of a prothetic continuum .
