I would like to conduct a study on young girls who were born to a young mother (15-19) and their liklihood to follow in their mother's footsteps. I believe that their is a negative correlation between the age of a mother when they bore their child and the child's liklihood of becoming sexually active at a young age. For this experiment, I would need to set up a longitudinal study. I would select young girls in the age groups of 11, 13, and 15 who were born to a young mother. The subjects would need to be followed-up on twice a year for ten years in order to determine a relative time at which they became sexually active. This, of course, will require the subjects to be completely honest and open about their sex life. A control group of young girls born to parents at a more mature age will also be tracked twice a year. This will help to determine whether or not all girls are likely to become sexually active at an earlier age, or if having been born to a young mother correlates with earlier sexual activity in young girls. The independent variables involved in this experiment will include: having been born to a young mother, age, culture/ethnic background, and socioeconomic status. The dependent variable will be the age at which the young girl becomes sexually active.
