What is the most appropriate assessment to evaluate paulo’s social and emotional development ?

15-year-old Paulo is brought to the clinic for a routine check-up. His parents express concern that he has become more withdrawn and spends much of his time alone in his room. They report that Paulo used to be more social and active in family activities. They also mention that he has been sleeping more than usual and his academic performance has declined. Paulo’s parents believe that he might be dealing with stress related to school, but they are unsure about what to do.
