FACTORIAL INVARIANCE OF PERSONALITY RATINGS

K uusinen , J. Factorial invariance of personality ratings. Scand. J. Psychol ., 1969, 10 , 33–44—Three studies employing the same set of 33 personality rating scales are described. (I) Five factor structures of the scales, derived from ratings of five groups of stimuli, were compared. (2) One subject rated different personality concepts three times at one week's intervals. (3) 12 individual factor structures were compared to the factor structure computed from peer ratings of a group of 39 subjects. Results: (a) the factor structure of the scales was largely independent of stimuli, (b) the structure for an individual was stable, (c) the group structure represented the individual's structure, ( d ) differences between group and the individual structure and between individuals were negligible.
