The traditional method of measuring self-esteem has been to construct instruments based on their face validity, even though this approach has been shown to involve many difficulties when deriving scales for subjective dimensions such as self-esteem. An alternative approach to the measurement of self-esteem is based on techniques of psychophysical scaling and places respondents on their own subjective dimensions derived from judgments of trait self-descriptions. To test the technique, 35 college students, participating in groups of 10-15, judged similarity for 210 pair comparisons involving 20 traits plus the concept "yourself." Results indicated the weight vectors and person locations provided alternative ways for representing individual differences relative to the evaluative dimensions obtained from multidimensional scaling. Students generally placed more emphasis on the horizontal dimension than on the vertical dimension, and person locations were primarily on the evaluative side of the horizontal dimension. The location of individuals was not correlated with traditional measures of self-esteem. Charting coordinates for the self-concept in multidimensional trait space holds potential for producing a new measure of self-esteem. (JAC)
