An Item Analysis of the Adjustment Questionnaire

Following a preliminary analysis of 782 personality test items, a questionnaire of 97 items of the yes-no type was administered to a group of 276 freshman men. A statistical analysis of the results was made, and the list was reduced to 67 items. Tetrachoric correlation coefficients were computed between these 67 items and these were submitted to a factor analysis, using Thurstone\u27s technique. It was found that at least 12 factors are necessary to account for the intercorrelations between the items. Of the 67 items, 38 were found to be sufficiently pure that they had factor loadings greater than.50 for only one factor
