Concurrent and Predictive Validity of an Early Language Screening Program

Abstract

The efficacy of screening 2-year-old children for language delay using a parent-report questionnaire was investigated in three studies. The Language Development Survey (Rescorla, 1989) was mailed to 650 families at the time of their child's second birthday. Fifty-three percent of the surveys received by parents were completed and returned. Screening outcomes were then compared, in double-blind fashion, with the results of comprehensive clinical evaluations at ages 2 (N = 64) and 3 (N = 36). Parents' report of the size of their children's expressive vocabularies was highly correlated with clinical language measures at age 2. Children who screened positive performed significantly poorer than children who screened negative on standardized language tests and on measures taken from spontaneous conversation. The screening program demonstrated excellent sensitivity and specificity for identifying language delay at age 2 but somewhat lower levels for predicting developmental status one year later.

Screening for Speech and Language Delay in Preschool Children: Systematic Evidence Review for the US Preventive Services Task Force

“…Eleven studies from 10 publications used instruments that take Յ10 minutes to administer for children up to 2 years old, including the Early Language Milestone Scale, 30,55 Parent Evaluation of Developmental Status, 56 Denver Developmental Screening Test II (language component), 57 Pediatric Language Acquisition Screening Tool for Early Referral, 52 Clinical Linguistic and Auditory Milestone Scale, 58 Language Development Survey, [59][60][61] Development Profile II, 57 and the Bayley Infant Neurodevelopmental Screener 62 (Table 4). Of these studies, 6 tested expressive and/or receptive language, 30,52,55,57,62 3 tested expressive vocabulary, 59-61 1 tested expressive language and articulation, 56 and 1 tested syntax and pragmatics.…”

“…58 For the 10 fair-and good-quality studies that provided data to determine sensitivity and specificity, sensitivity ranged from 22% to 97% and specificity ranged from 66% to 97%. 30,52,[56][57][58][59][60][61][62] Four studies reported sensitivity and specificity of Ն80% when using the Early Language Milestone Scale, 30 the Language Development Survey, 59,60 and the Clinical Linguistic and Auditory Milestone Scale. 58 The study of the Clinical Linguistic and Auditory Milestone Scale also determined sensitivity and specificity by age and reported higher sensitivity/ specificity at 14 to 24 months of age (83%/93%) than 25 to 36 months of age (68%/89%) for receptive function but lower sensitivity/specificity at 14 to 24 months of age (50%/91%) than 25 to 36 months of age (88%/98%) for expressive function.…”

“…[36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] (Supplemental Table 3). Supplemental Table 4 describes relevant screening instruments.…”

“…32,33,42,43 Both studies examined the accuracy of the screener at 2 years in relation to the reference standard (a diagnostic tool) at both 2 years and 3 years. In the LDS study, 43 sensitivity for detecting a language delay at 3 years was 67% (91% at 2 years).…”
