A mother brings her 9-year-old son to the PMHNP to evaluate him for attention deficit-hyperactivity disorder based on a chief complaint of lack of concentration in class and at home. The PMHNP finds the child also exhibits fatigue, insomnia, anhedonia, and agitation. The nurse practitioner plans to involve both the parent and the teacher in the assessment of these symptoms. Which of the following assessment tools will the PMHNP most likely utilize?

Choice A reason: The BDI is a self-report tool for depression in adults and is not validated for assessing children with ADHD or overlapping mood symptoms. Choice B reason: The Child Behavior Checklist is a parent- and teacher-report questionnaire that evaluates behavioral and emotional problems in children. It is comprehensive and useful for assessing ADHD symptoms as well as comorbid mood disturbances in children. Choice C reason: Connor's Parent Teacher Rating Scales specifically assess ADHD symptoms but may not fully capture depressive or mood-related symptoms, which are also present in this child. Choice D reason: CDI 2 assesses depressive symptoms in children, but it does not evaluate ADHD symptoms, attention problems, or teacher-reported behavioral difficulties.
