Gender, achievement, motivation, and mental health among adolescents in the 1990s

This dissertation explored gender differences in motivation, achievement choices, and mental health among gifted and non-gifted adolescents in the 1990s. Data were from a longitudinal survey study of motivation, activity choice, mental health, and peer and family relationships among 1179 European American children. The first study hypothesized that there would be few or no gender differences in math and science motivation and achievement choices among high school students in the 1990s because of increased efforts to encourage young women to enter technology, physics, and applied mathematics fields in recent decades. Overall, giftedness was a stronger determinant of attitudes and behaviors than gender. Growth curve hierarchical linear modeling (HLM) with an accelerated longitudinal design of three cohorts from first through twelfth grades showed that math expectancies and values declined over time for all students, with the exception of gifted girls whose math expectancies increased. There were no gender differences in math, but there were gender differences favoring males in science expectancies and values in both ability groups. Cross-sectional analyses in high school showed that non-gifted girls took AP calculus less frequently than non-gifted boys, and gifted girls took AP physics less frequently than gifted boys. Girls in both ability groups had higher educational aspirations and expectations than boys, and gifted girls planned to go into math and physical science jobs more frequently than gifted boys. It is suggested that educators now need to focus on girls in science, and physics in particular. The second study hypothesized that gifted girls would experience more psychologic conflict over career vs. family and more academic anxiety and depression than their peers. Growth curve analysis with HLM showed that it was non-gifted girls, rather than gifted girls, who experienced the most psychological distress on all mental health indicators from seventh through twelfth grades. Furthermore, gifted girls' mental health was positively, not negatively, affected by their desire to have children. In sum, across both studies, it was non-gifted girls who had the lowest motivation and mental health. In addition to implications of these findings, the nature of giftedness in this sample is also discussed.
