HÄrnqvist, K. Canonical analyses of mental test profiles. Scand. J. Psychol., 1973, 14, 282–290.‐The one‐year stability of profiles of mental test scores from four PMA factors was studied in grades 4 through 9 (ages 11 to 16) by means of canonical correlations and estimates of “redundancy” between batteries. Change in test content within the framework of the same PMA factors meant a greater decrease in profile similarity than change in time for parallel content. The same components were needed for explaining the variance common to two batteries of tests with a year's interval as to batteries of simultaneous tests. In the discussion the present approach is related to other methods for studying profile similarity, profile reliability and profile change.
