To investigate the usefulness of the communication domain in the Korean version of Ages and Stages Questionnaire (K-ASQ), and short form of the Korean version of MacArthur-Bates Communicative Development Inventories (M-B CDI-K), as screening tests for language developmental delay.
Data was collected between April 2010 and December 2013, from children who visited either the Department of Physical Medicine and Rehabilitation or the Developmental Delay Clinic, presenting with language development delay as their chief complaint. All the children took the short form of M-B CDI-K and K-ASQ as screening tests, and received diagnostic language assessments including Sequenced Language Scale for Infants (SELSI) or Preschool Receptive-Expressive Language Scale (PRES).
A total of 206 children, mean age 29.7 months, were enrolled. The final diagnoses were developmental language disorder, global developmental delay, autism spectrum disorder, cerebral palsy, etc. The M-B CDI-K short form and the communication domain of the K-ASQ had 95.9% and 76.7% sensitivity, and 82.4% and 85.3% specificity, with regards to diagnostic language assessments. The M-B CDI-K short form showed higher negative predictive value and better accuracy than the communication domain of the K-ASQ.
The screening ability of K-ASQ was not sufficient for children with language development delay, and the M-B CDI-K short form should be implemented for additional screening.

To investigate the usefulness of MacArthur-Bates Communicative Development Inventories-Korean (M-B CDI-K) short form as a screening test in children with language developmental delay.
From April 2010 to May 2012, a total of 87 patients visited the department of physical medicine and rehabilitation of National Health Insurance Service Ilsan Hospital with the complaint of language developmental delay and were enrolled in this study. All patients took M-B CDI-K short form and Sequenced Language Scale for Infants (SELSI) or Preschool Receptive-Expressive Language Scale (PRES) according to their age.
The study group consisted of 58 male patients and 29 female patients and the mean age was 25.9 months. The diagnosis are global developmental delay in 26 patients, selective language impairment in 31 patients, articulation disorder in 7 patients, cerebral palsy in 8 patients, autism spectrum disorder in 4 patients, motor developmental delay in 4 patients, and others in 7 patients. Seventy-one patients are diagnosed with language developmental delay in SELSI or PRES and of them showed 69 patients a high risk in the M-B CDI-K short form. Sixteen patients are normal in SELSI or PRES and of them showed 14 patients non-high risk in the M-B CDI-K short form. The M-B CDI-K short form has 97.2% sensitivity, 87.5% specificity, a positive predictive value of 0.97, and a negative predictive value of 0.88.
The M-B CDI-K short form has a high sensitivity and specificity so it is considered as an useful screening tool in children with language developmental delay. Additional researches targeting normal children will be continued to supply the specificity of the M-B CDI-K short form.
