Underrepresentation of women in higher status, traditionally male occupations has been attributed to sex-role socialization and to discrimination. Female students entering traditionally male professions may suffer many of the same pressures that have prevented other women from entering these fields. Undergraduate women (N=64) and men (N=21) in engineering, management, and pre-medicine programs completed a questionnaire which included measures of personality variables and external factors related to achievement and measures of current achievement. Also included were measures of expectations of future success, aspirations, and five stress/health measures. The means for women and for men were similar on all measures; but correlations with expectations, aspirations, and the stress/health measures appeared to differ by sex. Prediction equations for these variables for women were also tested. Current achievement was the best predictor for expectations and aspirations. Personality measures were more important and external factors slightly less important for aspirations than for expectations. The combined predictors accounted for a significant amount of the variance in each of the predicted variables. Many of the predictors that were related to one of the stress/health measures were unrelated or inversely related to another, indicating different underlying processes. (Author/NRB)
