Personality Traits and Self-Reported Vocal Fatigue and Other Voice Measures Among Teachers.
Article in Journal of voice : official journal of the Voice Foundation, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrevious research has examined the correlation between certain personality traits and specific voice disorders. These studies indicated that a predictive relationship exists between an individual's personality and their likelihood of experiencing certain types of voice disorders. The personality type classified as "extravert" was most commonly correlated with voice problems associated with high vocal use such as inflammation or nodules.
aimThe purpose of this study was to determine if a relationship exists between self-reported vocal fatigue, demographic characteristics, such as assigned sex at birth and age, perception of current voice condition, aerodynamic measures, and voice acoustic parameters with any of the five personality traits measured by the Big Five Personality Index: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness. We hypothesized that vocal fatigue scores and spirometry measurements may be good predictors of specific personality traits, and therefore, can be useful measures to complement vocal assessment.
methodsParticipants in this cross-sectional correlational study included 73 full-time elementary and middle school teachers. Participants completed the Vocal Fatigue Index (VFI) and the Big Five Inventory (BFI)-10 personality index; further, microphone recordings were collected from a battery of voice tasks in addition to spirometry. Descriptive analyzes of the dependent variables (BFI personality traits) and independent variables (demographics, acoustics, spirometry, and VFI total score) were performed, calculating frequency values. Kruskal-Wallis tests were conducted to evaluate independent variables' differences across the scores of the five BFI personality traits. The association between the independent and dependent variables was then investigated using a Generalized Estimating Equations multinomial logit model. The level of significance was defined at 0.05, and the associations are expressed as betas and standard error. RESULTS AND
conclusionThe results suggest that high scores for the traits of extraversion and agreeableness were both predicted by lower scores on the VFI (P ≤ 0.05), indicating that individuals with lower perception of vocal fatigue may be more likely to be identified as extraverted and/or agreeable personalities. These results support previous study's conclusion as well as add additional insights that could be translated into screening protocols and additional supportive care of occupational voice users.
