Teenage pregnancy rates in the U.S. are among the highest in the world for industrialized countries. The generally accepted reason is not that American teenagers are more sexually active but that they contracept less than do teenagers in other industrialized countries. This dissertation reports on a study that was undertaken for two purposes. One purpose was to develop and test two models of contraceptive choice among American teenagers: a "likelihood-of-use" model to predict the likelihood of sexually active teenagers' using contraception, and a "medical-or-nonmedical" model to predict whether teenagers who use contraception are likely to use medical or nonmedical methods. The second purpose was to explore the level of support for the two models among black and white teenagers separately. The theoretical underpinning of the models is value-expectancy theory. The models' exogenous variables are based on the prevailing strategy for preventing teenage pregnancy among American teenagers, a strategy initially advocated by Joy G. Dryfoos. The strategy involves the use of access-to-contraception programs, educational programs, and life options programs. The data used in the study were on 449 subjects drawn from the 1979 National Survey of Young Women, a probability-sample survey of women in the U.S. aged 15-19. The subjects were …

The aim of this study was to identify the characteristics of non-traditional female students and their perceived reasons for university studies.

This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.
