Does Shyness Influence the Self-Perception of Vocal Symptoms, Public Speaking, and Daily Communication?

Objectives: The present study aimed to characterize and to verify the relationship between shyness and self-assessment of vocal symptoms, public speaking, and aspects of daily communication.

Methods: This is an observational, analytical, and cross-sectional study. Two hundred and sixty-four male and female participants, with a mean age of 21 years and without any vocal disorder. To measure the outcomes, the participants' scores were measured using the following self-assessment instruments: Revised Cheek and Buss Shyness Scale, Voice Symptom Scale, Self-Statements during Public Speaking Scale, and the Daily Communication Self-evaluation Questionnaire. A descriptive and inferential analysis of the data was performed.

Results: Shy persons had higher vocal symptomatology scores in the limitation, emotional, and total domain. Furthermore, they scored higher on the negative aspects of public speaking and lower on its positive aspects. In addition, they showed weaker loudness and higher pitch in daily communication, compared with nonshy persons. Statistically significant correlations were found between positive shyness scores and all domains of vocal symptoms, negative aspects of public speaking, and pitch in daily communication. However, negative correlation was found between the positive aspects of public speaking and loudness in daily communication.

Conclusion: Shy persons have a higher self-evaluation with regard to the negative and less positive aspects of public speaking and most vocal symptoms, as well as weaker loudness and higher pitch in daily communication when compared to nonshy persons. The greater the perception of shyness, the greater the self-assessment with regard to daily communication and vocal symptoms and the negative aspects of public speaking.
