Early Identification of Developmental Delays or Concerns to Receipt of Early Intervention Services Among Infants and Toddlers: A Systematic Review Brian Barger, PhD+^ Cathy Rice, PhD +National Center on Birth Defects and Developmental Disabilities, Centers for Disease Control and Prevention (CDC) ^Disability Research and Dissemination Center University of South Carolina AUCD November 11, 2014 Early Identification Early identification of developmental concerns allows families to seek intervention during the crucial period of early child brain, body, and behavioral development It is never too late to start supports and services for a person in need. Starting as early as possible is best. Overview Individuals with Disabilities Act (IDEA) Part C – Funding for early intervention (EI) support services for infants and toddlers with developmental delays and their families (IDEA, 2004; PL 108-466) – Each state establishes coordinated EI systems including: Child Find Referral Assessment Individualized Family Service Plan (IFSP) professional development systems (Blackman, Healy, & Ruppert, 1992; Bricker et al., 2013) Early Identification is a Public Health Concern Part C Child Find is a major system used to identify children early for EI services, however: Many children with developmental disabilities (DD) are not identified as early as they could be Only 30% of children with DD identified before Kindergarten (Palfrey, 1987) EI can significantly impact acquisition of important life skills for many children with disabilities (Guralnick, 1997; 2011; NPDC, 2014) • 1 in 6 children will have a developmental disability • 1 in 68 with autism* (Boyle et al., 2011; CDC, 2014) *Autism Spectrum Disorder (ASD) Early Identification is a Process Part C and early identification literature Much research on the effectiveness of EI – Including Part C Much research on the effectiveness of developmental screeners (Macy, 2012) Very little research on Part C systems tracking data from Child Find to assessment to entrance to EI Purpose of Study Characterize peer-reviewed literature on reporting data following populations of young children with developmental risk through the process of early identification leading to Part C EI services Systematic Review: Search Search Engines: – ERIC, PsycINFO, Proquest, and Web of Science Search terms: – – individuals with disabilities education act, part c, part h, child find, title V, 108-446, 105-17, 99457, 101-476, 102-119, and 105-17 paired with: monitor*, surv*, eligib*, screen*, ancil*, assess*, interven*, established risk, category one, presumed eligibility, established condition or presumptive eligibility. Systematic Review: Search Ancestral searches from studies considered for the final analysis January 1986 to July 2013. – January 1986 IDEA was re-authorized with the Part C addition Model of Extracted Data Study Inclusion Criteria Published since 1986 Cited Part C of IDEA in – – abstracts or literature reviews At least two of the key steps from the Model – – – (A) the total population of children monitored (B) children screened positive, referred for and/or received a developmental evaluation; or (C) children deemed or assessed eligible for and/or actually receiving Part C EI services Study Exclusion Criteria Pre 1986 publication Psychometric studies Professional opinions/training Search Flow Chart (Final N = 39) Study Codes Setting – – – Primary Specialized All data broken down according to these classifications Study Codes Descriptive – – – Years of publication Sample age range State/region Study Codes Descriptive – sample type Cohort/epidemiological population, Convenience/community samples, or Other/unreported Study Codes Descriptive – analysis focus Systems level Measurement/individual level (excluded), or Both Study Codes Descriptive – Centrality of reference to IDEA law Minor – One reference Moderate – Two references Major – Three + references Study Codes Descriptive – Journal/academic-field Developmental/disability Education/intervention Medical Study Codes Model systems – Systems following total populations of children from screening or referral to actually entering EI – Primary model Specialized model Criteria: Recent publication (i.e., since 2006) Presence of all 3 major model data components Data on the number of children who entered EI Not national survey data.
