Abstract


The aim of this study was to investigate the usefulness of a clinical screening test [the Korean Infant and Child Developmental Test (KICDT)] compared to language specific tests: the sequenced language scale for infant (SELSI) and the Preschool Receptive-Expressive language Scale (PRES) in children with delayed language development. A retrospective chart review was conducted on 615 children who visited the Department of Pediatrics at Chonbuk National University Hospital from January 2013 to December 2016. All patients were evaluated with KICDT as a clinical screening test and SELSI or PRES as a language specific test. Language Developmental Quotients (LDQs) from the KICDT were compared with the Receptive Language Quotient (RLQ) and expressive language quotient (ELQ) from the SELSI or PRES. The sensitivity, specificity and predictive values of LDQ of KICDT were calculated by comparing with SELSI/PRES. Language DQs from the KICDT were significantly correlated with the RLQ (r=0.706), ELQ (r=0.768), and total language quotient (TLQ) (r=0.766) from the SELSI/PRES (p<0.05). In cross tabulation, the patients belonging to the retardation groups in both KICDT and SELSI/PRES were 417 (67.8%). Otherwise, patients belonging to the normal group in KICDT but not in SELSI/PRES were 151 (24.6%). Sensitivity and specificity of LDQ of KICDT relative to SELSI/PRES were 72.3% and 92.2% respectively (p<0.05). Our data suggests that clinical screening tests alone, not cumbersome language specific tests, can determine language developmental delays in children.
