The study described in this report was conducted in order to determine the effects of self concept and selected demographic and economic variables on attrition. Data are drawn from a group of 74 disadvantaged adult students who enrolled in a college preparatory program at the Syracuse Educational Opportunity Center (S.E.O.C.). Demographic variables considered were age; sex; ethnicity; marital, employment, and household status; source and amount of income; urban, suburban, or rural residence; and household size. Academic variables included course load, achievement test score, and significant others, while self concept was measured with a number of variables concerning identity and social, ethical, and personal attitudes. Results of the study indicate: (1) significant differences in self concept between the study group and the norm group of the Tennnessee Self-Concept Scale, in the areas of self criticism, identity, behavior, total variability and definiteness; (2) aignificant differences between early and late dropouts in terms of California Achievement scores and days and hours of instruction, but none in terms of employment status or position as head of household.
