Background: Clinical experiences emphasize the possible role of parental attitudes and behaviours in shaping stuttering behaviors however, the number of studies in this area is still insufficient. Objective: Our aims were to compare parental attitudes in children with and without stuttering and to determine the effect of parental attitudes on stuttering severity. Methods: We used an age and gender matched case control design with 24 children with stuttering and 22 healthy school children. Demographic information form and Parental Attitude Research Instrument (PART) were enrolled by the mothers. Results: According to our results; there was a statistically significant difference in parental attitudes of children with and without stuttering. Our results showed that excessive maternal control of the child and the expectations of obedience from the child more frequently observed in parents of the children with stuttering. Also there was a significant positive correlation with the severity of stuttering and excessive maternal control of the child, the expectations of obedience from the child and marital conflict. Discussion: In conclusion, there was an important difference in parental styles of study group and this difference was related to the severity of stuttering. Clinicans should address parental attitudes in this samples.
