Abstract
Assessment of children with autism spectrum disorder must characterize everyday functioning, co-occurring conditions, and individual support needs alongside diagnostic classification. This narrative review examines the evidence and clinical rationale for integrated clinical, biological, and functional assessment in pediatric autism and presents SMART-NB as a proposed framework for organizing these dimensions. The review combines selected clinical guidelines and research publications with conceptual analysis and a targeted literature update, distinguishing established assessment principles from the author-developed framework. Three findings emerge. First, standardized observational instruments contribute to diagnosis but require interpretation alongside developmental history, caregiver information, differential diagnosis, and clinical judgment. Second, co-occurring sleep disturbances, gastrointestinal symptoms, nutritional problems, sensory impairments, and pain can influence behavior and participation and warrant clinically directed evaluation; their association with autism does not establish causation. Third, symptom severity does not fully describe adaptive functioning, supporting assessment across functional domains and everyday contexts. SMART-NB proposes connecting clinical, medical and biological, and demand-related profiles with seven functional domains, individualized goals, and longitudinal reassessment. The demand dimension examines available capacity, physiological and emotional burden, environmental requirements, and supports. Its proposed contribution is to document how assessment findings inform care priorities. Existing multidimensional approaches already address overlapping aspects of this task; the incremental value of this particular organization remains untested. The reviewed evidence supports multidimensional assessment but does not establish the validity, reliability, or clinical utility of SMART-NB. This review is not systematic, and extension beyond autism remains a hypothesis requiring condition-specific evaluation. Development should proceed from operational specification, independent content assessment, and feasibility studies to the evaluation of measurement properties and comparative clinical outcomes.
