In 1995, Linda M. Dinerman, Michele D. Wilson, Anne K. Duggan and Alain Joffe, conducted a study to determine the differences in long-term pregnancy prevention in teens between the use of implants, oral contraceptives, and other contraceptive methods. Their study employed a broad experiment that focused on 166 girls between the ages of 12 and 18 who were all sexually active. The experimental study discovered that the use of Norplant was a more effective method of contraception than any other method studied. The authors relied upon a hospital-based clinical setting in which to observe the participants. The study employed a quantitative method of research and was based upon solid theory. The results of the study can be considered statistically significant. APA format. 5-pages, bibliography lists 7 sources.
