Comparing five-factor personality traits and psychological distress between dysphonic patients and individuals with vocally healthy voices.

INTRODUCTION

It was reported that voice can carry information about personality and psychological distress. In the current study, the relationship between five-factor personality traits and psychological distress with voice was enlightened from diverse aspects.

METHODS

A total of 119 participants (55 with and 64 without dysphonia) sustained vowels /a/ and /i/, read six standard sentences, and answered a question. Three raters auditory-perceptually evaluated the vocal samples using the Persian version of CAPE-V. The participants were distributed into four groups (vocally healthy, mild, moderate, and severe dysphonia). They completed two questionnaires: NEO Five-Factor Inventory (NEO-FFI) and Depression, Anxiety, and Stress Scale-21.

RESULTS

Results showed that the conscientiousness (U = 1146.500, z = -3.27, p = .001) in the dysphonia group was significantly less than the vocally healthy group. Depression (U = 1381.000, z = -2.03, p = .042) and anxiety (U = 1181.000, z = -3.10, p = .002) in the dysphonia group were significantly higher than in the vocally healthy group. In comparing different abnormal overall voice qualities, the mild dysphonia group revealed significantly lower conscientiousness (p = .001) and significantly higher anxiety (p = .002) relative to the vocally healthy group.

CONCLUSIONS

Findings indicated that the conscientiousness trait could play an influential role in persons with dysphonia and its psychological status. The voice care team should consider conscientiousness and psychological distress during the assessment and treatment of dysphonic patients.
