The Common Item Problem in Measurement.
Cohen, Arie; Farley, Frank H.
Procedures for analyzing common item effects on interscale structure were reviewed and a study using smallest space analysis of the California Psychological Inventory (CPI) reported. Solutions of three matrices--intercorrelation matrix of the original CPI scales, of reduced scales (with common items removed), and of the number of common items--were compared visually, and by interpoint distance correlations and configurational similarity analyses. Marked similarity among the original structure, the item-overlap-free structure, and the built-in structure was observed. It was concluded that common items magnify an intrinsic structure already existing among scales, and that the common-item problem is not a serious one in such personality assessment. (Author)
