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 compare and analyze the clinical characteristics of children with delayed language acquisition due to two different diagnoses, which were specific language impairment (SLI, a primarily delayed language development) and global developmental delay (GDD, a language delay related to cognitive impairment).
Among 1,598 children who had visited the developmental delay clinic from March 2005 to February 2011, 467 children who were diagnosed with GDD and 183 children who were diagnosed with SLI were included in this study. All children were questioned about past, family, and developmental history, and their language competences and cognitive function were assessed. Some children got electroencephalography (EEG), in case of need.
The presence of the perinatal risk factors showed no difference in two groups. In the children with GDD, they had more delayed acquisition of independent walking and more frequent EEG abnormalities compared with the children with SLI (p<0.01). The positive family history of delayed language development was more prevalent in children with SLI (p<0.01). In areas of language ability, the quotient of receptive language and expressive language did not show any meaningful statistical differences between the two groups. Analyzing in each group, the receptive language quotient was higher than expressive language quotient in both group (p<0.01). In the GDD group, the Bayley Scales of Infant Development II (BSID-II) showed a marked low mental and motor quotient while the Wechsler Intelligence Scale showed low verbal and nonverbal IQ. In the SLI group, the BSID-II and Wechsler Intelligence Scale showed low scores in mental area and verbal IQ but sparing motor area and nonverbal IQ.
The linguistic profiles of children with language delay could not differentiate between SLI and GDD. The clinicians needed to be aware of these developmental issues, and history taking and clinical evaluation, including cognitive assessment, could be helpful to diagnose adequately and set the treatment plan for each child.

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.

Objective: To evaluate the characteristics of speech-language development and to find out the relationship between them and radiological findings, and mental/motor developmental quotient in the children with cerebral palsy and other delayed development.
Method: Fifty-eight children with cerebral palsy or delayed development were evaluated with Bayley scales of infant development, brain magnetic resonance imaging (MRI), and single photon emission computerized tomography (SPECT). At the same time, the speech-language development using several evaluation batteries was assessed.
Results: Most of the children with cerebral palsy or delayed development showed delay in speech-language development. There was no relationship between speech-language development and presence of the lesion on brain MRI or SPECT, and mental/motor developmental quotient.
Conclusion: Speech-language development was delayed in most of the children with cerebral palsy or other delayed development. Therefore, early interventions for speech-language development and comprehensive speech therapy are required for improving functional outcome in these children.
Objective: To evaluate the pattern of developmental delay of language and to correlate the language with other developmental areas in cerebral palsy children.
Method: Sequenced Inventory of Communication Development (SICD) was studied in 31 children with cerebral palsy of age ranging from 11 months to 48 months. Korean Denver Developmental Screening Test (DDST) was also performed in 18 children simultaneously.
Results: On SICD, 10 children (32.3%) showed the receptive language delay and 13 children (41.9%) showed the expressive language delay. Among 15 spastic quadriplegic children, 40% showed the delay of receptive language development, 53.3% showed the delay in expressive language development. Among 10 spastic diplegic children, 30% showed the delay of both receptive and expressive language development. One spastic right hemiplegic child showed a delay of expressive language development, but 4 left hemiplegic children showed the normal language development. One hypotonic cerebral palsy child showed a delay of both receptive and expressive language development.
The expressive language was delayed more than the receptive language.
SICD correlated highly with the language sector of DDST. And both SICD and DDST language sectors correlated with the other sectors of DDST (personal-social, fine motor-adaptive, gross motor), especially with the fine motor sector (r=0.912, 0.918, 0.976, p＜0.001).
Conclusion: There is a considerably high incidence of developmental delay of language in cerebral palsy children, especially among spastic quadriplegic children.
The early evaluation and treatment for the developmental delay of language need to be included in a general rehabilitation program for the cerebral palsy children.
