This study examined differences and similarities between male and female patterns of adult development by comparing equivalent male and female subject groups with regard to psychological well-being, locus of control, and job satisfaction. Subjects were 74 male and 81 female elementary and secondary school teachers who were either between the ages of 22 and 31 years or the ages of 42 and 51 years. All subjects completed the Affective Balance Scale, the Internal-External Locus of Control Scale, the Job Satisfaction Index, and a demographic questionnaire. A 2 x 2 between subjects multivariate analysis of variance was performed on the three dependent variables associated with gender and age. The results revealed that the variables of psychological well-being, locus of control, and job satisfaction were all significantly related to the main effect of both gender and age, and to the interaction between gender and age. Middle-aged subjects were less satisfied with their jobs and were more externally controlled than were younger subjects; middle-aged women were found to be the least satisfied with their jobs. Female subjects also showed lower psychological well-being and a more external locus of control than did male subjects, suggesting that women have different developmental patterns than do men. (NB)
