Objectives:
The purpose of this study was to determine whether patients with functional voice disorders show voice activity and participation profiles different from those of the organic and neurogenic groups.
Methods:
The Korean Version of the Voice Activity and Participation Profile (K-VAPP) was administered to 200 participants (150 patients with functional, organic, and neurogenic voice disorders, 50 for each etiological group, 50 controls without vocal complaint). The K-VAPP subscale scores of the etiological groups were compared, controlling for age, professional use of voice, and severity of voice disorder measured by overall severity of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V).
Results:
Results of a one-way analysis of variance indicated significant differences in the overall severity across groups (neurogenic > functional = organic > control). Among four groups, the organic group showed higher mean Z-scores of the K-VAPP than the control group, and the functional group showed higher mean Z-scores of the K-VAPP than the organic group. Compared with the neurogenic group, the functional group showed lower mean Z-scores for total score, Activity Limitation Score, SUB3, and SUB5. A comparison among three etiological groups showed that the functional group did not show higher scores than the organic group. On the contrary, the functional group showed a lower total score, Participation Restriction Score, and score for subsection 3 (effect on daily communication) than the neurogenic group.
Conclusions:
Psychometric assessment of voice disorders using the K-VAPP could provide clinicians with baseline information that is applicable to various voice disorders. Further studies pertaining to the follow-up of voice disorders with various etiologies are needed to extend its clinical usefulness.
