ELVS investigators look at various parts of childhood communication development. Here are some key findings you have shared with us so far.
By four years of age, the incidence of stuttering onset over time was 11.2% in the ELVS group. This is much higher than reported previously. Only 6.3% of children had recovered from stuttering in the first 12 months after onset of stuttering. This is lower than previous reports of recovery rates. Recovery rates were higher for boys, those who did not repeat whole words at onset of stuttering, and for children who had reduced severity when stuttering began. Children who stuttered had stronger language skills at four years and better health-related quality of life than the non-stuttering group. Early onset of stuttering was not associated with language delay, social and environmental factors, or shyness/withdrawal before stuttering started. The ELVS data showed that the negative affects people tend to associate with stuttering, were not the norm in the ELVS group in the first year after stuttering onset.
Health professionals can reassure parents that onset of stuttering is not unusual up to four years of age and seems to be associated with rapid growth in language development.
Language and memory
At age five we looked at the language and memory of some of the children who were saying few words at age two. The most important findings from this study were:
- Late starters can catch up, with language skills at age five similar to those of children who produced more words at age two.
- Those late starters who continued to have difficulties with language at age five were likely to have memory skills that were less advanced.
A number of children have been diagnosed with autism during the study. Twenty children were identified by four years, and almost 50 by the age of seven. Many of the later diagnosed cases have Asperger Syndrome. We are interested particularly in early signs of autism that differentiate children with autism spectrum disorder from children with other delays and disabilities.
The early development of children with autism was compared to that of other ELVS children. We found that children with autism produced less communicative gestures at two years of age than children with developmental delay, or language impairment or typically developing children. The study continues to look for further early markers as the children grow older and it is hoped the results of the study will lead to earlier detection of autism in the future.
ELVS has looked at what factors help predict a child's readiness to start school at five-six years of age that might be identifiable before school entry. The most helpful characteristics in being ready for good progress at school were:
- Level of language expression
- Level of language understanding
- Pre-literacy skills including knowledge of letters and their sounds.
Recent research highlights
- Infants with multiple moderate-to-severe regulatory problems (persistent crying, irritability, and problems with sleeping and feeding) have more than 10 times greater odds of experiencing significant mental health concerns during childhood compared with infants who are settled.
- Children with developmental language disorder have lower of quality of life than their typically developing peers at 9 years, and showed declining quality of life from 4 to 9 years (as reported by their parents). Co-occurring social–emotional problems at age 4 and 7 are important factors related to low quality of life for children with developmental language disorder at 9 years.
- 65% of children with confirmed stuttering at age 4 recovered by age 7. Children who had recovered from stuttering were more likely to have stronger language skills than children whose stuttering persisted. There is indication that stronger communication skills at the age of 2 years, particularly in girls, has higher odds of recovery from stuttering.
