Final answer:
Stephanie, a self-care adolescent, is less likely to exhibit improved academic performance compared to peers who are supervised by adults, although she may see increased independence and responsibility.
Step-by-step explanation:
According to the textbook, compared to young people who are supervised after school by adults, Stephanie, a self-care adolescent, will likely experience all of the following except: increased independence, greater responsibility, and higher risk of behavioral problems. The one aspect she is not more likely to experience compared to her supervised peers is improved academic performance. Adolescents in self-care may develop skills related to independence and responsibility due to managing their own time and activities. However, without adult supervision, they might also be at a higher risk of engaging in behaviors that can lead to problems due to peer influence and a lack of guidance. On the contrary, adult supervision is generally associated with positive outcomes like better grades and fewer school behavior problems, as it provides a structured environment that can support academic success.
