Abstract

Purpose: Catastrophization refers to the cognitive distortion that is experienced by patients with several diseases who suffer from pain. There is some evidence that catastrophization may be found in patients with voice disorders. The Voice Catastrophization Index (VCI) was developed in English to measure catastrophization in patients with dysphonia. The goal of this research was to translate and validate the Persian version of the VCI (P-VCI) for use with Persian-speaking people in Iran and elsewhere. Methods: This was a prospective and cross-sectional study. First, the questionnaire was translated, then its various psychometric properties were investigated. Results: There was a significant difference in mean P-VCI score between participants with and without dysphonia (p < 0.001). Test-retest reliability for the total score of P-VCI was excellent (ICC = 0.94, p < 0.001), as was its internal consistency, as determined by Cronbach's alpha coefficient (α = 0.956). Confirmatory factor analysis revealed that some of the indices show a good fit for the 3-subscale model. There was a moderate correlation in criterion-related validity between the P-VCI and Voice Activity Participation Profile-Persian version (r = 0.644, p < 0.001). Conclusions: The translated test exhibited satisfactory psychometric properties. The P-VCI is a valid and reliable tool for the assessment of catastrophization in persons with voice disorders. © 2019 S. Karger AG, Basel. All rights reserved.
