ABSTRACT
Objectives
The purpose of this study is to investigate 22 risk factors for speech sound disorders (SSDs) and to find out whether there are differences in risk factors for each subtype of SSDs of Dodd’s model.
Methods
Sixty-two children with SSDs aged 3-9 years participated in the study, and 22 risk factors reported in literature were investigated through parental interviews and a nonverbal intelligibility test. Children with SSDs were divided into children with articulation disorders, phonological delays, and consistent/inconsistent phonological disorders.
Results
As a result of the principal component analysis, 22 risk factors were classified into 1) language and gross motor development, 2) gender and early development, 3) otitis media with effusion, 4) socioeconomic status, and 5) family history. Among all risk factors, only general developmental delay around 2 years of age showed a significantly different frequency among subtypes of SSDs.
Conclusion
This study directly investigated the risk factors of children with SSDs and classified a number of risk factors into five categories. This study suggests that if children show early general developmental delays, they should be closely monitored and early evaluation and interventions should be planned.
