Vocal activity profile and dysphonia coping strategies in subjects with laryngeal cancer treated with radiotherapy

Translation and Validation of an Arabic Version of the Voice Disability Coping Questionnaire

OBJECTIVES/HYPOTHESES

Voice disorders can significantly affect the quality of life. This study aimed to translate, culturally adapt, and validate an Arabic version of the voice disability coping questionnaire (A-VDCQ) for use in Arabic-speaking populations with dysphonia.

STUDY DESIGN

This was a cross-sectional study involving the translation and cultural adaptation of the VDCQ into Arabic. The validation process included reliability and validity assessments. Participants were categorized into cases (individuals with dysphonia) and controls (individuals without dysphonia) to compare coping strategies between the two groups.

METHODS

ccccccccThe 15-item VDCQ was translated from English into Arabic using the forward and backward translation methods. The questionnaire's reliability was assessed using Cronbach's alpha and test-retest reliability (intraclass correlation coefficient, ICC). Validity was evaluated by comparing cases and controls using the Mann-Whitney test. Differences in coping strategies across different diagnoses were examined using the Kruskal-Wallis test.

RESULTS

The A-VDCQ demonstrated satisfactory internal consistency (Cronbach's alpha = 0.769) and excellent test-retest reliability (ICC = 0.993). Significant differences in coping strategies between the cases and controls were also observed (P < 0.001), supporting the instrument's validity. Notably, item 4, which is related to information seeking, had the highest impact score among the cases. However, no statistically significant differences were found in coping strategies across different diagnoses (P = 0.249).

CONCLUSIONS

The A-VDCQ demonstrated robust psychometric properties for assessing coping strategies in individuals with voice disorders and such strategies' potential implications for clinical practice and research.

Self-assessment of teachers with normal larynges and vocal and osteomuscular complaints

INTRODUCTION

Teachers face vocal problems related to long periods of speech and increased sound pressure, as well as environmental noise, inadequate posture and tension of the cervical muscles.

OBJECTIVE

To verify the results of self-assessment of teachers with normal larynges and vocal and musculoskeletal complaints, and compare them with the reference values.

METHODS

Fifty-seven teachers, aged between 21 and 60 years (average 40.14 years) participated in the study. Anamnesis, otorhinolaryngological examination, hearing screening and self-assessment protocols were performed.

RESULTS

In the Nordic musculoskeletal questionnaire, the majority of teachers had discomfort in most parts of the body and in the situations evaluated; on the voice-related quality of life, the total and physical subscores were lower than the normative values while the emotional subscore was higher; regarding voice symptoms scale and vocal tract discomfort scale, the scores were higher than the normative values; in the hospital anxiety and depression scale, there was alteration in the total score; in the Vocal Activity and Participation Profile, the effects on work and emotion were above the normative values; on the University of Rhode Island change assessment-voice and on the voice handicap index there were no significant differences.

CONCLUSION

Most of the teachers presented vocal, musculoskeletal, and emotional complaints on the self-assessment results, what suggests excessive voice use as well as overload on the body muscles, including the larynx and vocal tract, and that they presented emotional changes. These aspects had an impact on their quality of life, but they showed no action in coping with the condition.
