Abstract
The 1969 male and female Mehrabian measures of achieving tendency are among the best-known measures of resultant achievement motivation. This study addressed the question of whether unique male and female items are necessary. Pearson product-moment correlation analyses on 83 male and 184 female undergraduates showed that females' scores on the unique male items correlated positively with their scores on the original female scale, and males' scores on the unique female items correlated positively with their scores on the original male scale. Coefficient alpha reliabilities of the original male and female forms were found to be acceptable. Cluster analyses showed that the Mehrabian items cluster in very similar ways for both males and females.
