In an earlier report of this project, French describes 28 temperament factors for which there is sufficient consensus in the literature to call them established. The specific objective of the present study is to determine, by means of factor analyses using newly constructed subscales, how well the 28 putative factors stand up. To this end a sample of 4000 recruits at the Navy Training Center in San Diego were tested with a complex design that permitted determination of the correlations among all 87 subscales but that required no individual to respond to more than 320 items. For further substantiation a second sample of 153 female and 92 male college students at the University of Oregon were given the entire battery of items. After item analyses and reliability determinations were made, 77 subscales survived. Correlation matrices were computed separately for the two samples and factor analyses performed. 22 minres factors were retained in each sample and rotated to maximum obliqueness using the direct oblimin method. Results are discussed separately for the two samples and compared across the two.
