This study sought to determine whether personality traits related to extraversion and impulsivity are more strongly associated with singers with nodules compared to vocally healthy singers and to understand the relationship between personality and the types of daily speaking voice use.
Weeklong ambulatory voice recordings and personality inventories were obtained for 47 female singers with nodules and 47 vocally healthy female singers. Paired tests investigated trait differences between groups. Relationships between traits and weeklong speaking voice measures (vocal dose, sound pressure level [SPL], neck surface acceleration magnitude [NSAM], fundamental frequency, cepstral peak prominence [CPP], and the ratio of the first two harmonic magnitudes [ ]) were examined using pairwise Pearson coefficients. Multiple regressions were performed to estimate voice parameters that correlated with two or more traits.
Singers with nodules scored higher on the Social Potency scale (reflecting a tendency toward social dominance) and lower on the Control scale (reflecting impulsivity) compared to the vocally healthy singers. In vocally healthy singers, vocal dose measures were positively correlated with a combination of Wellbeing (i.e., happiness) and Social Potency, mean SPL was positively correlated with Wellbeing, SPL variability was positively correlated with Social Potency and negatively with Harm Avoidance, and CPP mean was positively correlated with Wellbeing. Singers with nodules had a negative correlation between NSAM skewness and Social Potency. Both groups had negative correlations between mean and Social Potency and Social Closeness.
Singers with nodules are more socially dominant and impulsive than vocally healthy singers. Personality traits are related to daily speaking voice use, particularly in vocally healthy singers. Individuals with higher levels of traits related to happiness and social dominance and lower Harm Avoidance tended to speak more, with higher laryngeal forces, with more SPL variability, and with more pressed glottal closure, which could increase risk of phonotrauma.
本研究旨在确定与外向和冲动相关的人格特质是否与结节患者相比，与嗓音健康的歌手更为密切相关，并了解人格与日常言语嗓音使用类型之间的关系。
对 47 名声带结节患者和 47 名嗓音健康的女性歌手进行为期一周的动态嗓音记录和人格量表测试。配对检验用于研究两组之间的特质差异。采用两两 Pearson 系数检验人格特质与一周内嗓音测量指标（嗓音剂量、声压级[SPL]、颈部表面加速度幅度[NSAM]、基频、倒频谱峰突出度[CPP]和前两个谐波幅度比[ ]）之间的关系。采用多元回归分析来估计与两个或多个特质相关的嗓音参数。
与嗓音健康的歌手相比，声带结节患者在社交能力量表（反映出社交支配倾向）上的得分较高，而在控制量表（反映冲动性）上的得分较低。在嗓音健康的歌手组中，嗓音剂量指标与幸福感（即幸福感）和社交能力呈正相关，平均 SPL 与幸福感呈正相关，SPL 变异性与社交能力和回避伤害呈正相关，与 CPP 均值呈正相关，与幸福感呈正相关。声带结节患者的 NSAM 偏度与社交能力呈负相关。两组患者的 均值与社交能力和社交亲密性呈负相关。
声带结节患者比嗓音健康的歌手更具社交支配性和冲动性。人格特质与日常言语嗓音使用有关，尤其是在嗓音健康的歌手组中。具有较高的与幸福感和社交支配性相关的特质以及较低的回避伤害特质的个体，往往会发出更多的声音，声带的力量更高，SPL 变异性更大，声门关闭更紧，这可能会增加发生语音创伤的风险。
