Validation of Cognitive Problem-Solving and Movement Infant-Toddler IGDIs for Screening and General Outcome Progress Monitoring

This study will examine the reliability and validity of two Individual Growth and Development Indicators (IGDIs) — the Early Cognitive Problem Solving Indicator (EPSI) and the Early Movement Indicator (EMI) — designed for screening and progress monitoring in intervention decision making with infants and toddlers with and without disabilities. High-quality services for young children with or at risk for disabilities increasingly rely on the use of data for decision making. The IGDIs were designed to meet this need. They are fully developed brief assessments with evidence of feasibility for practitioners to administer. This project will conduct parallel studies to determine whether the EPSI and EMI are reliable and valid, sensitive to growth over time, and have predictive utility for screening decisions.
