Final answer:
Older children and adolescents with mental health disorders or substance abuse issues predominantly do not receive sufficient treatment, which can lead to negative academic and behavioral consequences, affecting both their personal futures and broader societal systems.
Step-by-step explanation:
For older children and adolescents with an identified mental health disorder or substance abuse issue, the vast majority do not access or receive adequate treatment or services. Challenges associated with untreated mental health conditions and substance abuse can lead to various negative outcomes, such as poor academic performance, truant behavior, increased potential for dropping out of school, and challenges in securing employment. The long-term effects of child abuse also contribute significantly to these issues, resulting in increased risk for physical and mental health problems, including psychiatric disorders, all of which can shape educational and behavioral outcomes. These difficulties extend beyond the individual, affecting societal systems such as healthcare, education, and criminal justice.
