Insights
Many preschool children need special support due to undiagnosed functional difficulties, particularly in speech, language, and peer interaction. A functional approach is recommended over traditional disability categories for accurate prevalence estimation.
Area of Science:
- Child Psychology
- Special Education
- Early Childhood Development
Background:
- Preschools serve a critical role in identifying developmental needs.
- Understanding the prevalence of special support requirements is essential for resource allocation.
- Demographical and environmental factors within preschools may influence children's needs.
Purpose of the Study:
- To determine the prevalence of children needing special support in preschools (ages 1-6).
- To identify the specific functional problems exhibited by these children.
- To analyze these problems in relation to preschool context factors.
Main Methods:
- A survey was distributed to 1138 preschools across two Swedish counties.
- Preschool teachers' perceptions of children needing support were collected.
Main Results:
- The majority of children needing special support were undiagnosed.
- Common difficulties included speech, language, and peer interaction challenges.
- These functional difficulties were prevalent across the surveyed preschool population.
Conclusions:
- Both diagnosed and undiagnosed children present similar functional difficulties.
- Traditional disability categories underestimate the number of children needing support.
- A functional, needs-based approach is recommended for future studies and support identification.
Aim:
To investigate the prevalence of children who are in need of special support in the total population of children attending preschools (CA 1-6) in two Swedish counties, and the functional problems exhibited by the children in relation to demographical and environmental factors in the preschool context.
Method:
Survey distributed to (N = 1138) preschools in two Swedish counties.
Results:
The majority of children perceived by preschool teachers and in need of special support were undiagnosed children with functional difficulties related to speech, language and interaction with peers.
Conclusion:
Undiagnosed and diagnosed children share the same type of difficulties. Thus, in estimating the prevalence of children in need of special support in a preschool context, traditional disability categories capture only a small proportion of the children experiencing difficulties. Therefore, a functional approach in studies of children in need of special support is recommended.
