Summary
Children with vocal fold nodules (VNs) exhibit distinct personality traits, including higher emotional reactivity and lower agreeableness and conscientiousness. These traits may influence VN development and voice therapy outcomes, suggesting personality assessment is crucial for managing pediatric voice disorders.
Area of Science:
- Speech and Hearing Science
- Developmental Psychology
- Personality Psychology
Background:
- Vocal fold nodules (VNs) are common lesions in children, often linked to phonotrauma.
- The Trait Theory of VNs suggests specific personality characteristics may predispose individuals to developing VNs.
Purpose of the Study:
- To investigate the relationship between personality traits and the presence of VNs in children.
- To examine personality differences between children with VNs and control groups using the Trait Theory of VNs framework.
Main Methods:
- A case-control study involving children with VNs (N=39) and two control groups: voice disordered controls (VDCs, N=40) and vocally normal controls (VNCs, N=40).
- Parents completed the Inventory of Child Individual Differences, assessing the Big Five personality superfactors and 15 lower-order traits.
Main Results:
- Children with VNs showed significantly higher Neuroticism (emotional reactivity) compared to VNCs.
- Children with VNs exhibited lower Agreeableness (less compliant, more antagonistic) and lower Conscientiousness (distractible, disorganized) than VNCs.
- Both voice disordered groups had elevated Neuroticism scores and the 'Negative Emotions' trait.
Conclusions:
- A combination of high Neuroticism, low Agreeableness, and low Conscientiousness may contribute to VN development in children.
- The identified personality profile in children with VNs aligns with that of adults, supporting the Trait Theory of VNs across age groups.
- Clinicians should consider children's personality traits during the assessment and management of voice disorders, including VNs, as it may impact therapy success.

504
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Gordon Allport, often regarded as the father of American personality psychology, developed a theory that emphasized the importance of understanding people in their present lives rather than focusing on their past, as psychoanalysis did. Allport believed that personality should be studied in healthy, well-adjusted individuals rather than those with psychological problems. He was particularly interested in defining traits, which he saw as fundamental mental structures that guide behavior across...

1.3K
The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent...

Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
