Cross-cultural adaptation and validation of the Putonghua version of the voice activity and participation profile

Abstract

The present study aimed at translating the Voice Activity and Participation Profile (VAPP) into Putonghua with evaluation of the validity and reliability so as to provide an alternative instrument to quantify the influence on the quality of life by dysphonia in Putonghua-speaking Chinese. Seventy-seven subjects were recruited from the Beijing Tong Ren Hospital, affiliated with the Capital Medical University. Among the subjects recruited, 45 subjects, who were diagnosed with various types of vocal pathologies, were assigned to the dysphonic group and the remaining 32 subjects were assigned to the non-dysphonic group. The results suggested that the Putonghua version of the VAPP contained items which were able to measure the impact on the quality of life by dysphonia in dysphonic subjects and the scores were found to have high correlation with the scores in the Putonghua version of the Voice Handicap Index-10. Also, the Putonghua version of the VAPP had high test-retest reliability and internal consistency. Therefore the Putonghua version of the VAPP would be a valid and reliability instrument in quantifying the impact on the quality of life by dysphonia in the Putonghua-speaking Chinese.
