The ELCI is a rating scale that elicits information about a child’s observed receptive and expressive language and social/play skills. The ELCI can be completed by a Rater; a parent, caregiver, teacher, or day-care provider, then scored and interpreted by an Assessor; an SLP, school psychologist, neuropsychologist, or other professional. It can be used as a companion to directly administered tests and provides normative data in all three domains based on the reported observations, which can assist with eligibility and diagnostic information. The ELCI is especially helpful to use with children who are not able to participate in direct testing or who function differently across different environments. The ELCI provides normative information about:
The ELCI was standardised on a nationally representative sample of 605 children ages 18 months through 5 years, 11 months.
The ELCI can be completed in about 15 minutes by an adult familiar with the child’s behaviours. Scoring by a professional Assessor can be completed in 5–10 minutes. Scaled scores are provided for each subtest, and a standard score is provided for the overall score. Discrepancy scores allow comparison of performance across domains.
Cronbach’s alpha values ranged from 0.91 to 0.98 for subtest and overall scores. Test-retest correlations were 0.93 to 0.99 for subtest and overall scores. The ELCI was shown to differentiate individuals with autism spectrum disorder, social communication disorder, attention-deficit/hyperactivity disorder, speech and/or language delay, and Down syndrome from typically developing peers.
