This study utilized a canonical correlation procedure to investigate the construct validity of the Activity Vector Analysis (AVA, Form E) by comparing it to the Sixteen Personality Factors Questionnaire (16PF, Forms A and B). All subjects (N = 114; 57 males and 57 females) were from the greater Kansas City area and included students in continuing education classes at the University of Kansas, working spouses of graduate students in psychology, and employees from two large manufacturing companies. Examination of the descriptions of the dimensions defined by the obtained structure vectors associated with each instrument based on the canonical correlation linear composites suggests that construct validity for the Activity Vector Analysis relative to the Sixteen Personality Factors Questionnaire exists. Given the support for the construct validity of the Activity Vector Analysis and the fact that the AVA is an instrument that takes little time to administer, it is suggested that the AVA be employed more frequently in the assessment of personality.
