Summary
This study explored voice disorder classification using discriminant and cluster analysis in 128 patients. Findings revealed four distinct patient clusters, with psychological factors significantly differentiating them.
Area of Science:
- Laryngology
- Psychology
- Data Analysis
Context:
- Investigating the classification of voice disorders.
- Utilizing discriminant and cluster analysis for patient stratification.
- Examining 21 variables from 128 patients with diverse voice pathologies.
Purpose:
- To explore patient classification in voice disorders.
- To determine if discriminant analysis could differentiate diagnostic groups.
- To identify distinct patient clusters using hierarchical cluster analysis.
Summary:
- Discriminant analysis failed to differentiate patients based on initial diagnoses.
- Hierarchical cluster analysis identified four patient clusters.
- Clusters showed limited correlation with phoniatric diagnoses but were significantly associated with psychological variables like anxiety, emotionality, and extraversion.
Impact:
- Highlights the role of psychological factors in voice disorders.
- Suggests a potential for data-driven patient stratification beyond traditional diagnoses.
- Provides insights into the complex interplay between psychological state and vocal pathology.
