Language Delay in 2-Year-Olds.
Because language delay tends to persist, is predictive of later learning problems, and is closely associated with psychiatric disorders, it is important to identify language delay as early as possible. In this study, language delay at age 2 was investigated in 502 children who attended physicians. Language assessment is not routinely carried out at this age because current screening instruments must be administered by a physician or his staff. For this research a screening test was devised which does not need a professional to administer it. The Language Development Survey (LDS) required the parent to indicate whether the child produced word combinations and to check off, on a list of 250 words, all words produced spontaneously. The criteria for "clear delay" were fewer than 30 words and/or no word combinations at age 2. In the first year of the study, 351 children were surveyed in five different pediatric groups; 14 percent met the clear delay criteria. The range across groups was from 9 to 17 percent, with the highest prevalence in an urban hospital medical clinic. In the second year, 151 children were surveyed in the same hospital medical clinic; 16 percent met the criteria for clear delay. The rate of clear delay was higher in boys than in girls. Total vocabulary size was significantly associated with sex and socioeconomic status, with girls and children in the upper social classes having larger vocabularies. Preliminary attempts to collect validity data on the LDS suggest that it will be useful in future research. (Author/CB)
