The purpose of the screening tools like MAYSI is to assess what aspect of youth?

The correct choice focuses on the use of screening tools like the Massachusetts Youth Screening Instrument (MAYSI) in evaluating the mental health and substance misuse issues among youth. These screening tools are designed to identify potential mental health disorders and substance abuse problems early on, which can be crucial for intervention and support. By assessing these aspects, practitioners can develop appropriate treatment plans and support mechanisms tailored to the individual needs of the youth, ultimately contributing to better outcomes.

In contrast, evaluating physical fitness pertains to a different context that does not relate to mental health or substance abuse assessments. Similarly, academic performance and social skills are not the primary focus of tools like MAYSI; rather, they target psychosocial factors that may influence a young person's behavior and development.
