Preliminary study of self-perceived communication competence amongst adults who do and do not stutter

Adults who stutter report a significant impact of stuttering on their quality of life, including negative thoughts and attitudes toward communication. In addition to this impact, adolescents who stutter also report lower levels of self-perceived communication competence (SPCC) compared to fluent peers. The purpose of this study was to extend the investigation of SPCC to adults who do and do not stutter. Additional aims investigated included if 1) SPCC predicted overall impact of stuttering, and, 2) stuttering frequency predicted SPCC among adults who stutter.

Twenty-four adults who stutter and twenty-seven adults who do not stutter matched for age, gender, and education completed the Self-Perceived Communication Competence Scale (Richmond & McCroskey, 1997). All participants who stutter completed the Overall Assessment of the Speaker's Experience of Stuttering (OASES [ages 18+]; Yaruss & Quesal, 2006) and speaking samples to measure stuttering frequency.

Adults who stutter reported significantly lower SPCC scale total scores than adults who do not stutter. For adults who stutter, lower SPCC scale scores significantly predicted more severe overall impact of stuttering as measured by the OASES. Stuttering frequency did not predict SPCC scale scores.

This is the first study to report differences in self-perceived communication competence between adults who do and do not stutter. Results suggest adults who stutter report lower self-perceived communication competence compared to adults who do not stutter. Adults who perceive themselves to have greater communication competence reported less severe overall impact of stuttering, and stuttering frequency did not influence SPCC. Clinical implications for intervention are discussed.
