Effects of Stuttering on Quality of Life in Adults Who Stutter

Stuttering is potentially a socio communicational problem, which has negative effects on individuals’ mental and emotional health and other aspects of life. Recognizing the quality of life (QOL) dimensions in adults who stutter can be useful in treatment planning and preventing later mental, emotional and social disorders.

This study aimed to investigate the QOL and its relationship with stuttering severity in adults who stutter.

This analytic-descriptive study was performed on 78 adults (61 males and 17 females) who stuttered and 78 normal control cases in Mashhad City, Iran. Short-form 36 (SF-36) questionnaire of QOL was used to collect data and the percentage of syllables stuttered (%SS) was determined in a spontaneous speech sample as a frequency measurement tool. Mann-Whitney test was used to compare data between the groups and ANOVA test was also used to evaluate the correlation between stuttering severity and QOL dimensions.

This study showed a significant difference between the groups in mean scores of QOL, general and emotional health, social and physical functions, vitality and role limitations made by physical and emotional problems (P < 0.05). No significant difference was found in pain between the groups and there was no significant relation between %SS and dimensions of QOL (P > 0.05).

Stuttering has negative effects on different dimensions of QOL among individuals. Thus, it is necessary to pay special attention to its prevention and treatment before it is developed into a completed and progressive condition.
