Self-efficacy and quality of life in adults who stutter.

PURPOSE

Self-efficacy has emerged as a potential predictor of quality of life for adults who stutter. Research has focused primarily on the positive relationship self-efficacy has to treatment outcomes, but little is known about the relationship between self-efficacy and quality of life for adults who stutter. The purpose of this mixed- methods study is to determine the predictive value of self-efficacy and its relationship to quality of life for adults who stutter.

METHOD

The Self-Efficacy Scale for Adult Stutterers and the Overall Assessment of the Speaker's Experience with Stuttering were administered to 39 adults who stutter, aged 18- 77. Percentage of syllables stuttered was calculated from a conversational speech sample as a measure of stuttered speech frequency. Qualitative interviews with semi-structured probes were conducted with 10 adults and analyzed using thematic analysis to explore the lived experience of adults who stutter.

RESULTS

Self-efficacy emerged as a strong positive predictor of quality of life for adults living with a stuttered speech disorder. Stuttered speech frequency was a moderate negative predictor of self-efficacy. Major qualitative themes identified from the interviews with the participants were: encumbrance, self-concept, confidence, acceptance, life-long journey, treatment, and support.

CONCLUSION

Results provide clarity on the predictive value of self-efficacy and its relationship to quality of life and stuttered speech frequency. Findings highlight that the unique life experiences of adults who stutter require a multidimensional approach to the assessment and treatment of stuttered speech disorders.
