Abstract

Objectives: This study examined the association between voice disorders and personality by comparing a heterogenic group of dysphonic patients to non-dysphonic speakers using the NEO-FFI big-five personality inventory. Methods: A group of 100 dysphonic patients diagnosed with 24 different pathologies was compared to 149 non-dysphonic speakers. Inter-group differences on the five NEO-FFI scales were evaluated using three analysis approaches, a general comparison between the dysphonic and non-dysphonic groups and arranging pathologies using a categorical and a continuous approach. Results: Of the five NEO-FFI scales, Openness emerged as the single personality trait that yielded a statistically significant difference between the dysphonic group and the non-dysphonic group (P < 0.001). Moreover, when the 24 pathologies were arranged categorically, people with structural pathologies were lower on the Openness scale than non-dysphonic speakers (P < 0.001). Similarly, when pathologies were arranged continuously, people with pathologies characterized by high organicity were low on the Openness scale compared to the non-dysphonic group (P < 0.001). Conclusions: This study represents a new approach to examining the association between voice disorders and personality. Openness emerged as the single personality trait that repeatedly and consistently differentiated between dysphonic and non-dysphonic people and among specific pathologies, using all analysis approaches. Our findings suggest that examining a spectrum of pathologies, rather than focusing on a particular pathology, provides a new perspective and sheds light on the complex association between voice disorders and personality.
