One can analyze the data separately for each order to see whether it had an effect. A Framework For Addressing the Needs of Students Prenatally Exposed to Alcohol and Other Drugs. Specifically, we hypothesized that lower levels of intrauterine exposure to substances, lower household substance use, lower exposure to violence, lower rates of parental incarceration, greater parental supervision, and greater neighborhood cohesion would be associated with greater adolescent behavioral resilience. This kind of assignment, forcing you to get your ideas reduced in a small space matches the kinds of assignments that professionals have all the time — this assignment will help prepare you for this kind of assignment in your future. Between-subjects experiments have the advantage of being conceptually simpler and requiring less testing time per participant. Issues of Ethics The study of adolescents behavioral changes affect the society hence the moral ethics of the community must be revisited and checked together with the adolescents for a better future. Regulation also is how children react to challenges.
To measure depressive tendencies, Kessler et al. Infant Development Outcomes; A Family System.

This is also a great way to get feedback on some of your own ideas and to determine if they are worth exploring in greater depth.
