Relationships Among Personality, Daily Speaking Voice Use, and Phonotrauma in Adult Female Singers.
Laura E Toles, Nelson Roy, Stephanie Sogg and 5 others
PMID 34731578WHAT IT FOUND
Singers with vocal fold nodules scored higher on social dominance and lower on self-control than healthy singers.
These personality traits helped distinguish the groups. However, the study design cannot prove these traits caused the voice problems.
Key findings
01Singers with nodules had significantly higher Social Potency and lower Control scores than matched healthy singers.
02A model using only Social Potency and Control scores correctly classified 69.1% of participants into their group.
03Personality traits were strongly linked to speaking voice patterns in healthy singers, but showed weak or no links in singers with nodules.

What it does not show
The study is cross-sectional, so it cannot determine if personality traits caused the nodules or if having nodules influenced the trait scores. The sample included only female singers, limiting generalizability to male singers or non-singers. Many participants were young students, so findings may not apply to established professional singers with longer career histories. Wearing the voice monitor may have changed how participants used their voice, especially those recently diagnosed with nodules.
Declared interests
Funding was provided by the National Institute on Deafness and Other Communication Disorders. The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that high social dominance and low self-control caused the vocal fold nodules. The study design compares two groups at one point in time and cannot prove cause and effect.
