Written language skills of children with cleft palate.

The written language abilities of children with cleft palates aged eight to 13 were studied to compare performance with norms for the Picture Story Language Test. Although intelligence of this sample, as measured by the performance portion of the WISC, was skewed toward the superior and very superior ranges, the group ranked below the 50th percentile in total words used, words per sentence, and syntax quotients. Also, percentile scores on the PSLT declined as the age of the subjects increased. These results differ from the Ebert, McWilliams, and Woolf (1974) study where younger children with cleft palates (ages six to eight) were found to exhibit age-appropriate written language. The influence of factors affecting language development among the cleft palate population, such as methods and success of management, hearing, articulation, intelligence, sex, and psychosocial adjustment needs to be further investigated.
