Subtypes of stuttering determined by latent class analysis in two Swiss epidemiological surveys.

Aims

Associations between stuttering in childhood and a broad spectrum of risk factors, associated factors and comorbidities were examined in two large epidemiological studies. Subtypes of stuttering were then identified based on latent class analysis (LCA).
