ABSTRACT
This is a case-control study investigating the personality profiles of children with vocal fold nodules (VFNs). Personality has been suggested as a contributing factor to VFN in adults and in children. However, previous studies in children have focused on psychopathologic traits and have reported contradictory findings. The aim of our study was to explore whether general, nonpathologic personality structure predicts the presence of VFN in children. Personality traits were measured in 34 children with VFN, aged 6.0-13.6, and 34 age- and sex-matched normophonic controls by means of a pediatric five-factor personality questionnaire. Children with VFN were found to be significantly more extroverted than controls (P = 0.022, d = 0.61), and a binary logistic regression showed that extraversion significantly predicted the presence of VFN in our population (P = 0.027). The clinical implications of the results are discussed.
