The Usefulness of M-B CDI-K Short Form as Screening Test in Children With Language Developmental Delay

Abstract

ObjectiveTo 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.MethodsFrom 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.ResultsThe 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.ConclusionThe 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.

The Comparison of M-B CDI-K Short Form and K-ASQ as Screening Test for Language Development

“…Screening tests developed for early detection of language developmental delay include the Clinical Linguistic and Auditory Milestone Scale (CLAM), M-B CDI-K, M-B CDI-K short form, and SELSI [571617]. The CLAM was developed by Dr. Capute in 1970s and standardized in the United States by Visintainer et al [18].…”

“…Both the K-ASQ and M-B CDI-K short form have already proven that they are reliable as well as valid [717]. Thus, they are ideal screening tests with various advantages for language development evaluation, though the M-B CDI-K short form has more advantages than the K-ASQ.…”

“…This test is composed of understanding score, expressing score, and playing with things or grammar score [7]. These scores were judged as either ‘high risk’ or ‘non-high risk’ by following the guideline.…”

“…When PRES was not adequate for some children with severe language delay, it was substituted by SELSI. The language developmental delay was defined as language age below two standard deviations when using SELSI, and language age was at least 1 year behind normal when using PRES [2789]. …”

“…Among them, the short form of the Korean version of MacArthur-Bates Communicative Development Inventories (M-B CDI-K) was readily available, and in our previous study, was verified as a reliable and valid screening test for language development delay in children [7]. …”
