[Psychological classification of functional voice disorders].
In an explorative study the classification of a collective of patients with different voice disorders by discriminant and cluster analysis was tried. 21 variables, obtained from 128 patients with various diagnoses of voice disorders, were used. A first discriminant analysis on the basis of diagnoses-groups permitted no differentiation. A subsequent hierarchical cluster analysis indicated a four-cluster-solution. The clusters showed only little association with the phoniatric diagnoses. Cluster 1 is characterized by patients with non-organic voice disorders. Cluster 2 is marked by emotional unstable patients with organic dysphonia. Cluster 3 consists of patients with psychosomatic dysphonia by laryngeal contact granuloma, and cluster 4 contains emotional stable patients suffering from organic dysphonia and from spasmodic dysphonia. Thirteen psychological variables discriminated the clusters significantly: Anxiety about appearing in public, emotionality (neuroticism), life satisfaction, aggressiveness, anxiety, about physical injuries, extraversion.
