A 10-year-old male with major depressive disorder was started on fluoxetine 10 mg daily eight weeks ago and increased to 20 mg at week four. His baseline Children's Depression Rating Scale-Revised (CDRS-R) total score was 62. At today's visit, his CDRS-R score is 44. His mother reports he is doing his homework more consistently and has resumed playing with neighborhood friends after school. His teacher completed a follow-up assessment noting improved classroom participation but continued inattention during morning lessons. The patient himself states he feels about the same and shrugs when asked about mood changes, though he smiles more during the interview and demonstrates improved spontaneous speech compared to baseline. The PMHNP notices a discrepancy between the child's self-report, the parent and teacher observations, and the standardized measure findings. The PMHNP is evaluating the overall treatment response. Which of the following best represents the appropriate evaluation?
