Many US State-wide screening initiatives (e.g., TN AAP, Iowa DoE) focus on detecting social-emotional/behavioral health problems (SEBH). Many health care providers and other professionals use broad-band screens for early identification, particularly measures focused on children’s skills/milestones. For SEBH-focused initiatives, should professionals view all domains of development or just SEBH risk? The goals of this study are to: a) Determine SEBH risk rates on PEDS®: Developmental Milestones(PEDS:DM®); b) Identify whether developmental delays are associated with SEBH risk; and c) Evaluate family psychosocial risk factors correlated with SEBH risk. The results should assist professionals with decisions about types of further assessment and interventions.
