M.A. (Industrial Psychology) / The object of this study is to determine the correlation between selfconcepts selfactualization and anxiety on the one hand and -achievement motivation, as applicable to persons in middle management positions in the mining industry. Four different psychological questionnaires were used that is the Achievement motivation questionnaire of Malan (1978) as adjusted by Pottas and Lessing (1979L the Selfconcept questionnaire of Vrey (1974)s the IPAT Anxiety scale and the Selfrealization questionnaire of Osrin {1972}. The four questionnaires were administered to 110 middle-managers in the mining industry. It was found that the sUbjects obtained relatively high scores on the self-images selfrealization s achievement motivation and the three components of achievement motivations namely selfdetermination, the urge to complete uncompleted tasks and goal directedness. The scores obtained on the anxiety scale were relatively low. It was further found that-there existed a negative linear correlation between anxiety and achievement motivation,- in contrast with the initial hipothesis, namely that a curvilinear correlation exists between the two variables. Selfconcept and selfrealization both yielded a positive linear correlation with achievement motivation and its three components; which confirms the hypothesis. It was found that anxiety formed a negative correlation with all the variables. A positive linear correlation was obtained between selfrealization and selfconcept.
