Abstract
The purpose of this study was to investigate the rate of language delay in toddlers, examining the relationship between language development and behavior problems and the difference in behavior problems among language disorder/non language disorder and language delayed/language normal groups. The participants, who were referred to psychiatry clinics and rehabilitation centers, comprised 145 toddlers (100 boys, 45 girls). The K-CBCL 1.5-5 and the Korean LDS were used as measuring tools. The results indicated that 90.3% of the clinic-referred toddlers were delayed in language. Additionally, vocabulary scores and withdrawal, DSM-affective problems and DSM-pervasive developmental problems scale showed a negative correlation. Considering sex, girls`s vocabulary scores showed negative correlation with withdrawal, internal problems, and DSM-pervasive developmental problems. For boys, there were only negative correlation with DSM-affective problems. Further, based on a clinician`s diagnosis, the non-language disorder group`s ADHD scale`s T scores were significantly higher than the language disorder group. Finally, based on LDS vocabulary cut-off, language the delayed groups` levels of withdrawal, sleeping problem, DSM-affective problems, DSM-pervasive developmental problems and T scores were significantly higher than the normal group. This study confirmed the characteristic of language delayed toddlers and the relationship with language development and behavior problems.
