Adaptation and Validation of the Persian Version of the Voice Handicap Index-10 (VHI-10).

OBJECTIVES: Voice disorders can profoundly impact health, quality of life, job performance, and social interactions. Traditional evaluations have expanded to include quality-of-life assessments, emphasizing self-reported outcomes. The Voice Handicap Index (VHI) stands out among relevant questionnaires, with the VHI-10 being a concise derivative. This study was conducted to translate and validate the Voice Handicap Index-10 (VHI-10) questionnaire for Persian speakers, enhancing clinical assessments of voice disorders and quality of life. METHODS: This cross-sectional study, conducted in Iran, involved (1) translating the VHI-10 into Persian, (2) confirming face and content validity using Content Validity Ratio (CVR), and Content Validity Index (CVI), and (3) evaluating its reliability through a survey. A panel of experts confirmed the validity, and reliability of the study, which was assessed using Cronbach's alpha, Spearman-Brown, and Guttman coefficients. The survey involved 225 participants, including 150 healthy people and 75 patients with voice disorders, who were selected using a convenience sampling method. RESULTS: All question items demonstrated a CVI greater than 0.79 and a CVR between 0.62 and 1. Reliability analysis yielded high Cronbach's alpha values for functional, physical, and emotional domains (0.909) and total (0.961). The mean overall scores of VHI-10 for healthy and disordered groups were 18.78 and 0.74, respectively. The VHI-10 effectively discriminated between healthy and disordered groups in all domains, with an accuracy of 97.33%. The determined cut-off point was 4.5, with a strong area under the Receiver Operating Characteristic (ROC) curve (0.989). CONCLUSION: This study successfully adapted and validated the Persian version of the VHI-10. The questionnaire demonstrated high reliability and validity, distinguishing between individuals with and without voice disorders. This Persian version is now a valuable tool for speech and language pathologists conducting clinical voice evaluations in Iran and also it could be applied in studies to determine the effects of voice problems on participant's quality of life.

Voice Handicap and Public Speaking Anxiety in Self-Assessment among Children with and without Vocal Fold Nodules.

PURPOSE: Vocal fold (VF) nodules are very common laryngeal lesion that affects people, including children as well. However, it has a negative impact on the communication and voice quality which is why it is important to study and measure it. Unfortunately, there may be factors which disturb examining process especially during questionnaire self-assessment. This study aimed to investigate whether public speaking anxiety (stage fright) correlates with scores on the Children's Voice Handicap Index-10 (CVHI-10) and to determine if children with VF nodules assess their voice similarly to those without such lesions. METHOD: Thirty-seven respondents at age 8-12 participated in the study. It was conducted the surveys: Children Voice Handicap Index-10 (CVHI-10), Stage Fright Scale - Children & Youth (SFS-CY), and Neuroticism subscale of the Big Five Questionnaire - Children (BFQ-C-Neu) and endoscopy laryngeal examination. The text describes the reliability analysis, means comparison, and correlation analysis. RESULTS: The measures used achieved a high level of reliability. There were no statistically significant differences in voice self-assessment scores between groups with and without VF nodules. Significant relationships were found between the CVHI-10 scores and all factors of the SFS-CY. CONCLUSIONS: The results reveal that children with VF nodules assess their voice similarly to those without laryngeal lesions. Correlation analysis shows significant relationships between voice handicap in self-assessment and stage fright factors. This may explain the lack of differences in CVHI-10 scores among groups; however, further research is needed to clarify this phenomenon.

Prevalence of Perceived Voice Disorders and Associated Risk Factors in Teachers and General Population in Croatia.

OBJECTIVES: There is no available data on the prevalence of voice disorders in Croatia. The objective of this research was to determine the prevalence of perceived voice disorders (PVD) in teachers and general population in Croatia using the Croatian Voice Handicap Index (VHI-HR) questionnaire. METHODS: This research was divided into two phases. In phase I, the potential of the VHI-HR questionnaire to distinguish individuals with and without voice disorders was assessed. A total of 113 participants completed the VHI-HR. Receiver operating characteristic analysis was performed. In phase II, a cross-sectional study was conducted. A total of 1898 participants, including 1088 teachers from 434 Croatian schools, and 810 nonteachers were included in the study. The questionnaire on sociodemographic factors, potential risk factors associated with voice disorders, and the VHI-HR was administered. The differences in the PVD prevalence in teachers and nonteacher adults and adverse effects of PVD were investigated. The multiple logistic regression model was used to examine the factors associated with PVD occurrence. RESULTS: In phase I, the cut-off point of 18.32 with 93.44% sensitivity and 98.08% specificity for VHI-HR was determined. In phase II, higher lifetime PVD prevalence was found among teachers. The point prevalence of PVD was 45.68% for teachers, and 21.11% for nonteachers. This study demonstrated that being a teacher, a woman, having a family history of voice disorders, reflux, working in environment with elevated noise levels, and having more than 30years of employment are associated with PVD occurrence. CONCLUSIONS: VHI-HR score of 19 and higher proves effective in distinguishing individuals with voice disorders from those without. The odds of having PVD for teachers are 2.83 times higher than for nonteachers. Risk factors for voice disorders, among others, include occupational use of voice and working in environments with elevated noise levels.

A Comparison of the Dysphonia Severity Index and Singing Voice Handicap Index Between Trained and Untrained Male Iranian Traditional Singers.

OBJECTIVES: This study aimed to compare trained and untrained Iranian traditional singers on the Dysphonia Severity Index (DSI) and the Singing Voice Handicap Index. The second objective was to examine the relationship between the DSI and Persian version of the Singing Voice Handicap Index (P-SVHI) scores in each group of trained and untrained Iranian traditional singers. STUDY DESIGN: This study is a comparative cross-sectional study. METHODS: This study included 17 trained male Iranian traditional singers who were compared with 17 untrained ones who were matched in terms of age. The P-SVHI was completed by trained and untrained Iranian traditional singers. Measures of jitter, lowest intensity, highest phonational frequency, and maximum phonation time (MPT) were obtained from each participant. The DSI scores were calculated using these values. RESULTS: Trained male traditional singers had an average age of 33.76 ± 7.45 years, 3.24 ± 1.85 hours of daily practice, 5.24 ± 3.78 years of training, 3.06 ± 2.65 no. of professional performances, and untrained singers had an average age of 32.76 ± 12.92 years, 1.53 ± 1.17 hours of daily practice, and 0.88 ± 1.65 no. of professional performances. Trained singers had lower P-SVHI scores and sub-scores, longer MPT, higher F0 high, lower jitter, and lower I low, resulting in higher DSI values (P < 0.05). There was no significant correlation between P-SVHI scores and DSI values in each group of trained and untrained Iranian traditional singers (P > 0.05). CONCLUSIONS: The results of this study show that the vocal abilities of professional vocalists are enhanced through voice training (higher DSI scores in trained singers vs untrained ones). Voice training can also help to lessen the perception of a handicap related to the singing voice. Hence, it may be necessary to consider alternative norms for the DSI and P-SVHI when administering them to patients who have undergone guided vocal training, such as voice/singing lessons. The current research indicates that the perception of singing voice handicap and DSI values are two distinct characteristics that do not have a significant correlation.

Population characteristics and self-assessment of speaking and singing voice in Polish contemporary commercial music singers-an exploratory, cross-sectional study.

Background: The domination of the Contemporary Commercial Music (CCM) industry in music markets has led to a significant increase in the number of CCM performers. Performing in a wide variety of singing styles involves exposing CCM singers to specific risk factors potentially leading to voice problems. This, in turn, necessitates the consideration of this particular group of voice users in the Occupational Health framework. The aim of the present research was threefold. First, it sought to profile the group of Polish CCM singers. Second, it was designed to explore the prevalence of self-reported voice problems and voice quality in this population, in both speech and singing. Third, it aimed to explore the relationships between voice problems and lifetime singing involvement, occupational voice use, smoking, alcohol consumption, vocal training, and microphone use, as potential voice risk factors. Materials and methods: The study was conducted in Poland from January 2020 to April 2023. An online survey included socio-demographic information, singing involvement characteristics, and singers' voice self-assessment. The prevalence of voice problems was assessed by the Polish versions of the Vocal Tract Discomfort Scale (VTDS) and the Singing Voice Handicap Index (SVHI). Also, a self-reported dysphonia symptoms protocol was applied. The perceived overall voice quality was assessed by a Visual Analogue Scale (VAS) of 100 mm. Results: 412 singers, 310 women and 102 men, completed the survey. Nearly half of the studied population declared lifetime singing experience over 10 years with an average daily singing time of 1 or 2 h. 283 participants received vocal training. For 11.4% of respondents, singing was the primary income source, and 42% defined their career goals as voice-related. The median scores of the VTDS were 11.00 (0-44) and 12.00 (0-40) for the Frequency and Severity subscales, respectively. The median SVHI score of 33 (0-139) was significantly higher than the normative values determined in a systematic review and meta-analysis (2018). Strong positive correlations were observed between SVHI and both VTD subscales: Frequency (r = 0.632, p < 0.001) and Severity (r = 0.611, p < 0.001). The relationships between most of the other variables studied were weak or negligible. Conclusion: The examined CCM singers exhibited substantial diversity with regard to musical genre preferences, aspirations pertaining to singing endeavors, career affiliations, and source of income. Singing voice assessment revealed a greater degree of voice problems in the examined cohort than so far reported in the literature, based on the SVH and VTDS.

Prevalence and Risk Factors of Voice Disorders Among Teachers in Saudi Arabia.

Introduction Voice is a crucial tool for communication, and voice problems are more likely to occur in professionals who frequently use their voice for work. Teachers, whose profession requires sustained vocal use, are particularly susceptible to occupation-related voice disorders. This study aimed to quantify the prevalence of voice disorders among teachers in Saudi Arabia, with the general population serving as a control group, and to identify associated risk factors. Methods A cross-sectional study was conducted utilizing an online self-administered questionnaire, which was completed by both teachers and the general population in Saudi Arabia. The latter group acted as a control. The questionnaire included sections on sociodemographic data, teaching patterns, symptoms of voice issues, and the Voice Handicap Index-10 (VHI-10) for assessing voice disorders among participants. Results The study included 640 participants, with 438 (68.4%) being teachers, the majority of whom were females (N = 406; 63.4%). The most common voice-related symptoms reported by teachers were hoarseness (N = 210; 37.9%) and dry throat (N = 147; 26.9%). Voice disorders, as determined by the VHI, affected 355 (55.5%) of the teachers. A high VHI score was associated with a diagnosis of voice disorders and GERD. There was no significant difference in the VHI scores between teachers and the general population (p > 0.05). Conclusion Teachers in Saudi Arabia exhibited a higher prevalence of voice disorders compared to the general population. Risk factors, such as smoking, longer teaching experience, and more teaching hours per week, were more common among teachers with voice disorders. Further investigative studies are warranted to elucidate the causal relationships between these variables and voice disorders.

Effectiveness of a Voice Training Program for Religious Officials in Turkey.

This study examines the effectiveness of a voice training program designed for Islamic religious officials, who are occupational voice users with a significant vocal load. The participants included 34 healthy religious officials whose acoustic measures were within normal voice ranges for healthy adults (jitter < 1%; shimmer < 3%) and reported no voice complaints. Participants were randomly divided into two groups (experimental, n = 17; control, n = 17). The two-stage voice training program consisted of 32 sessions over 8 weeks with informative and voice exercise stages. Objective and subjective voice measurements were performed at the beginning and end of the research. Objective measurements included fundamental frequency, percentage of vocal pitch perturbation (jitter), percentage of vocal intensity perturbation (shimmer), and harmonics-to-noise ratio. Subjective voice measurements included the Singing Voice Handicap Index, Vocal Fatigue Index (VFI), and Voice-Related Quality of Life (V-RQoL) scores. All initial measurements other than VFI scores were within acceptable limits for both groups. There were no significant differences between the groups initially (p > 0.05) and no significant changes in the control group in the second evaluation (p > 0.05). However, there was significant improvement in the experimental group after the training program in all measures, including VFI scores (p < 0.05). This study shows the positive results of a voice training program. Voice training should be integrated into the formal education of occupational voice users or in-service training programs of relevant institutions.

Voice Disorders Among Teachers in Taif City, Kingdom of Saudi Arabia.

Background Voice disorders (VD) pose significant challenges for teachers as they impact their professional and personal lives. Teaching requires extensive use of the voice, making teachers particularly susceptible to vocal health issues. VD can hinder the quality of education. Objectives This study aimed to comprehensively explore the prevalence, associated factors, and impact of VD among teachers and their health-seeking behavior regarding VD. Methodology A cross-sectional observational study was conducted in Taif City, Kingdom of Saudi Arabia (KSA), between November and December 2023. The data were collected through a questionnaire covering demographic variables, occupational factors, voice-related symptoms, associated health conditions, and the impact of VD. The statistical analysis was performed using SPSS Statistics version 26 (IBM Corp. Released 2019. IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY: IBM Corp.), and chi-squared tests were used to assess associations. Results The study involved 568 teachers, 61.8% of whom had VD. The study identified significant associations between VD and demographic characteristics, habits, and teaching-related variables. Age, gender, teaching subject, class size, and weekly teaching load were associated with the prevalence of VD. Hoarseness, throat pain, and throat dryness were prevalent symptoms among teachers with VD. The impact of VD on teachers was evident, with a considerable proportion reporting work absenteeism (28.7%) and even contemplating retirement due to voice problems (6.3%). Conclusion This study offers a nuanced understanding of VD among teachers in the Taif region, emphasizing the complex interplay of demographic, symptomatic, and behavioral factors. The findings underscore the need for targeted interventions, including awareness campaigns, preventive strategies, and streamlined healthcare access, to address the unique challenges that different subgroups of teachers face. Future research should further explore longitudinal trajectories and objective measures to enhance our understanding of VD in educational settings.

Dysphagia as a predictor of voice handicap and voice restoration in unilateral vocal fold immobility.

OBJECTIVE: Dysphagia is multifactorial in unilateral vocal fold immobility (UVFI). Severe dysphagia could indicate greater functional deficits in UVFI. The purpose of this study is to evaluate the association of dysphagia with the need for surgical voice restoration in patients with UVFI. STUDY DESIGN: Retrospective chart review. SETTING: Single-institution, tertiary referral center. METHODS: Records of UVFI patients from 2008 to 2018 were examined. Dysphagia severity was extracted from patient history. Etiology of UVFI and other relevant variables were analyzed to determine their association with dysphagia. Dysphagia severity and other clinical variables were then analyzed for their association with surgical voice restoration. RESULTS: Eighty patients met selection criteria out of 478 patients with UVFI. There was significant concordance between dysphagia severity extracted from patient history and patient-reported EAT-10 scores (R = 0.59, p = 0.000035). Patients' EAT-10 scores were correlated with VHI-10 scores (R = 0.45, p = 0.011). Severe dysphagia (p = 0.037), high VHI-10 score on presentation (p = 0.0009), and longer duration of hoarseness before presentation (p = 0.008) were associated with surgical voice restoration in UVFI patients. CONCLUSION: In this pilot study, severe dysphagia and increased voice handicap on presentation were associated with the need for surgical voice restoration in UVFI patients. Presenting dysphagia may be an additional variable for clinicians to consider for management of UVFI.

Vocal fold cryptococcal granuloma: A rare occurrence in immunocompetent patient.

INTRODUCTION AND IMPORTANCE: Cryptoccous infection or cryptococcosis is a severe opportunistic infection occurring mainly in immunocompromised patients. Laryngeal cryptococcus infection is rare. In an immunocompetent patient, inhaled corticosteroid was reported to be a possible risk factor. CASE PRESENTATION: We discuss a case of right vocal fold cryptococcus infection in a healthy, immunocompetent 71-year-old man with no history of inhaled corticosteroid, presented with hoarseness and intermittent aspiration symptom for 1 year duration. Further examination showed right anterior vocal fold mass with presence of right vallecular cyst. CLINICAL DISCUSSION: Patient underwent direct laryngoscopy, excision of right vocal fold mass and marsupialization of vallecular cyst. Histopathological examination revealed cryptococcal infection. Patient subsequently treated with oral fluconazole 400 mg daily for 6 months. To date, hoarseness and aspiration symptoms have resolved. CONCLUSION: We are sharing our experience in managing laryngeal cryptococcus infection in an immunocompetent patient where the associated risk factors discussed in previous literatures are absent.

The Relation Between Endoscopic and Subjective Laryngopharyngeal Reflux Signs, Vocal Tract Discomfort, Voice Handicap, and Voice Disorder Type: Same Yet Different?

OBJECTIVES: This study aimed to investigate the relation between subjective voice-related symptoms and endoscopic findings in patients with different etiology of voice disorder and vocally healthy subjects with and without laryngopharyngeal reflux (LPR). STUDY DESIGN: Retrospective cross-sectional study. METHODS: The study involved 149 participants (106 female, 43 male) including 125 with various voice disorders (functional, structural, and neurogenic) and 24 vocally healthy individuals. For self-rating the German versions of the Voice Handicap Index (VHI), Vocal Tract Discomfort (VTD) Scale, and Reflux Symptom Index (RSI) were applied, while endoscopic evaluations utilized the Reflux Finding Score (RFS) and Reflux Sign Assessment (RSA). Statistical analyses incorporated ANOVA with Bonferroni posthoc tests to identify group variations. Correlations between VTD Scale, VHI, RSI, RFS, and RSA were evaluated using Pearson's correlation coefficient. To examine test sensitivity and specificity for the VTD Scale and RSA, we performed a receiver operating characteristics analysis. Youden's-Index was applied to determine the cut-off-value with best discriminatory abilities. The diagnosis of LPR was assumed when the criteria of RFS > 7 AND RSI > 13 was met. RESULTS: Significant differences for all voice diagnosis groups and vocally healthy individuals for RFS and all three self-rating questionnaires were found. Moreover, there was significant correlation between VTD Scale and VHI and RSI as well as RSI and RFS, which was moderate, negative in the group of persons with LPR. However, there was no significant difference for RSA results between the vocally healthy or any diagnosis group. CONCLUSION: Thus, the RFS may be more suitable to predict reflux and voice-related symptoms. The VTD Scale is a useful instrument in screening voice disorders but also LPR and can therefore be used as a tool for decision-making when transferring to a specialist.

Self-Reported Voice-Related Quality of Life in Cochlear Implant Users

Objective: The aim of this study was to identify if cochlear implant (CI) users are perceiving a decrease in life quality due to voice problems. This study evaluated 43 CI user's perception of their voice and how it affects their quality of life through a survey. Approach: Forty-three CI users responded to a survey regarding their demographics, details about their CI, the Hearing Health Quick Test (HHQT), the Voice Related Quality of Life (V-RQOL), and the Voice Handicap Index-10 (VHI-10). The survey responses were analyzed using univariate linear regression analysis. Results: Few of the CI users scored below the cut off for normal voice related quality of life. CI users averaged 93.4 out of 100 on the V-RQOL and only four scored abnormally for the VHI-10. Lower scores on the V-RQOL were correlated with the participants having an associate degree and with participants visiting friends, family, and neighbors less often due to hearing loss. The VHI-10 scores were correlated with gender, education levels, difficulty in social situations due to hearing loss, noise exposure, and tinnitus. Limitations of the study: The small n was the primary limitation of this study. Originality: This study was one of the first to examine the voice-related quality of life in CI users. Conclusions: Overall, respondents did not perceive much voice-related difficulty. However, they were more likely to perceive voice-related difficulty if they experienced difficulty hearing in noise and avoided social situations due to hearing loss.

Objetivo: Este estudio identificó si los usuarios de implantes cocleares (IC) están percibiendo una disminución en la calidad de su vida debido a problemas de voz. Además, evaluó la percepción de la voz de 43 usuarios de IC y cómo afecta su calidad de vida a través de una encuesta. Enfoque: Cuarenta y tres usuarios de IC respondieron a una encuesta sobre su demografía, detalles sobre su IC, la Hearing Health Quick Test (HHQT), la Voice Related Quality of Life (V-RQOL) y el Voice Handicap Index-10 (VHI-10). Las respuestas de la encuesta se analizaron mediante un análisis de regresión lineal univariado. Resultados: Pocos usuarios de IC puntuaron por debajo del límite para calidad de vida relacionada con la voz. El promedio V-RQOL fue de 93,4/100; solo 4 participantes tuvieron puntuación anormal en VHI-10. Las bajas puntuaciones en V-RQOL se correlacionaron con título de asociado y menos visitas por pérdida auditiva; las puntuaciones VHI-10, con sexo, educación, dificultad en situaciones sociales, exposición al ruido y tinnitus. Limitaciones del estudio: La pequeña n fue la principal limitación de este estudio. Originalidad: Este estudio fue uno de los primeros en examinar la calidad de vida relacionada con la voz en usuarios de CI. Conclusiones: En general, los encuestados no percibieron mucha dificultad relacionada con la voz. Sin embargo, era más probable que percibieran dificultades relacionadas con la voz si tenían dificultades para oír en ruido y evitaban situaciones sociales debido a la pérdida auditiva.

Subjective Assessments of Voice in Parkinson's Disease Subjects with and without STN-DBS Therapy.

Introduction: The causal relation between STN-DBS and speech problems and the associated clinical features are in the incipient stages of being investigated. Methods: All the Parkinson's disease (PD) subjects with and without STN-DBS who applied to our movement disorders outpatient clinics between January 2022 and June 2022 and agreed to participate in the study were enrolled. The demographic data and clinical features were noted. Besides, the MDS-UPDRS was administered during the medication off-state in all subjects. All the participants completed the voice handicap index (VHI). Besides, the Freezing of Gait Questionnaire (FOGQ) and the quality of life (QoL) scales including the Parkinson's Disease Questionnaire (PDQ-39) and the Schwab and England Activities of Daily Living (ADL) scale were also administered to all the individuals. Results: We have included 66 patients with PD (F/M = 23/43). Thirty-five patients were those with DBS therapy whereas 31 patients were without. The results of the comparative analyses between the patients with and without DBS therapy revealed that the DBS group had a higher disease duration (P = 0.006) and FOGQ scores (P = 0.008). The VHI scores did not differ between groups (P = 0.577), and the correlation analyses did not reveal an association between the VHI scores and the duration of DBS therapy. However, the VHI scores correlated with the disease duration as well as the FOG scores. Conclusion: We did not find convincing evidence supporting the increased risk of speech disturbance with STN-DBS therapy. We suggest that the frequent existence of speech disturbance in this patient subgroup with STN-DBS is associated with the classical nature of PD.

Utility of Smart Phones as a Voice Acquisition Device for Assessing Pre and Post Treatment Voice Using PRAAT.

Voice assessment before and after treatment helps the clinician to assess the effectiveness of the treatment given and facilitates comparison between different treatment modalities. Voice handicap index -10(VHI-10) questionnaire is a tool which allows the voice to be evaluated subjectively from the patient's perspective. PRAAT is a freely available, software programme that acoustically analyse voice signals. Smart phones are widely used and the high quality of the embedded microphone in it makes it a suitable and easily available voice recording device. This study aims at using PRAAT and VHI-10 questionnaire in evaluating voice before and after treatment. The utility of smart phones as a voice acquisition device is also explored in the study. Prospective, observational study, carried out from 1st November 2019 to 30th September 2021in the ENT out- patient department at a tertiary hospital in Punjab. 58 patients complaining of dysphonia were enrolled consecutively in the study. All patients underwent detailed history, examination of the larynx using 70-degree rigid laryngoscope. The voice handicap was scored by (VHI-10) questionnaire and acoustic evaluation of voice was done using the PRAAT software. Patients' voice was further evaluated 3 months post-therapy with VHI 10 questionnaire and acoustic analysis. The parameters measured on PRAAT were mean pitch, jitter (local), shimmer (local), and mean harmonics to noise ratio (HNR). The voice was recorded using a smart phone and later transferred onto a laptop for analysis. The pre and post treatment acoustic parameters and VHI-10 scores were compared and correlated. There was significant difference (p < 0.001) between the pre and post treatment VHI-10 scores and all the acoustic parameters measured except for median pitch (p = 0.995). A poor positive correlation was found between the pre treatment VHI-10 scores and jitter(r = 0.188, p = 0.157) and shimmer (r = 0.288, p = 0.028) values. A negative correlation was observed between pre treatment VHI-10 scores and pitch (r = - 0.151, p = 0.259) and HNR(r = - 0.424, p = 0.001). Post treatment VHI-10 scores showed positive correlation with jitter (r = 0.302, p = 0.021) and shimmer (0.162, p = 0.225) values and negative correlation with pitch (r = - 0.10, p = 0.457) and HNR (r = - 0.356, p = 0.006) values. We found significant differences in the VHI-10 scores and PRAAT voice analysis results before and after treatment in patients complaining with voice change (dysphonia). VHI-10 questionnaire and PRAAT are good and convenient tools for assessing the voice subjectively and objectively. Only a poor to fair correlation was found between VHI-10 scores and PRAAT analysis results. More studies must be done to confirm the utility of smart phones as a voice acquisition device and PRAAT software in voice analysis.

Adaptation and validation of the Persian Version of the Singing Voice Handicap Index-10 (SVHI-10).

OBJECTIVES: Singers' self-reporting of their voice problems can be helpful in the treatment of voice disorders by speech-language pathologists (SLP), which requires a valid questionnaire. This study was conducted to translate and validate the Singing Voice Handicap Index-10 (SVHI-10) questionnaire in the Persian language. METHODS: This cross-sectional study was conducted in two main steps (1) translation of the questionnaire and determination of face and content validity and (2) survey of singers. The questionnaire was first translated by a SLP who was an expert in voice disorder and also proficient in the English language. The face and content validity of the questionnaire was confirmed by experts through impact score, content validity ratio, and content validity index. Then it was translated into English and adapted to its original version. A valid questionnaire was given to 70 singers to determine their ability to distinguish singers with voice problems from healthy singers and their internal consistency. RESULTS: The face and content validity of the questionnaire was confirmed without excluding any item. The results showed that the questionnaire has excellent internal consistency (α = 0.930). With the optimal cut-off point of 14.5, this questionnaire was able to identify singers with voice problems with 90% accuracy. Also, the sensitivity and specificity were 84.85% and 94.59%, respectively. Also, the area under the Receiver Operating Characteristic (ROC) curve was equal to 0.937. CONCLUSION: The results revealed that the Persian version of SVHI-10 is a reliable and valid instrument to identify singers with voice problems, so it can be used by SLPs.

Voice Handicap Index: Cut-Off Points for Screening European Portuguese With Voice Disorders.

OBJECTIVES: To determine cut-off values of the Voice Handicap Index (VHI) and the shortened version (VHI-10) for European Portuguese (EP) with voice disorders. In addition, to analyze the discriminatory power of individual items of the VHI-10 and the ability to detect differences in various Ear Nose and Throat (ENT) diagnoses. STUDY DESIGN: Cross-sectional cohort study. METHODS: All participants completed the EP VHI and a 4-point self-assessment of voice disorder severity. The case group (subjects with voice disorders) underwent assessment through strobovideolaryngoscopy examinations by ENT surgeons and perceptual analyses by speech-language pathologists (SLPs). In contrast, the control group was evaluated solely by SLPs. Data were analyzed using a receiver-operating characteristic curve to determine the accuracy and cut-off values of the VHI and VHI-10. RESULTS: The study involved a sample of 350 adults (171 cases and 179 controls), predominantly women aged 18-88 years. The area under curve (AUC) for VHI and VHI-10 was 0.997 [95% confidence interval (CI): 0.992-1] and 0.998 [95% CI: 0.995-0.999], respectively. Optimal cut-off values were identified as 13.5 for VHI (0.994 sensitivity and 0.989 specificity) and 5.5 for VHI-10 (0.977 sensitivity and 0.955 specificity). Each individual item within the VHI-10 significantly contributed to the overall assessment, exhibiting varying discriminatory power ranging from excellent (AUC = 0.937) to poor (AUC = 0.637). Significant differences were found in the case group between neurogenic disorders and healthy larynx (P = 0.014), structural and physiologic minor laryngeal abnormalities (P = 0.006), and inflammatory disorders (P = 0.043). CONCLUSIONS: The VHI and the VHI-10 exhibited accurate screening properties for predicting EP speakers with voice disorders.

Internal Consistency of the Voice Handicap Index in Individuals With Dysphonia: A Systematic Review and Meta-Analysis.

OBJECTIVE: To analyze the internal consistency of the Voice Handicap Index (VHI) for evaluating the vocal handicap of individuals with dysphonia. METHODS: This is a systematic review. Studies with a cross-sectional design and including a population of individuals with dysphonia, which validated the VHI and analyzed its internal consistency, were included. The following electronic databases were searched: Cochrane Library, EMBASE, LILACS, and PubMed, including Medline, Scopus, and Web of Science. A manual search was performed in gray literature through the Biblioteca Digital Brasileira de Teses e Dissertações and ProQuest Dissertation & Theses. In addition, the list of references of studies selected in the electronic search was mapped, and an expert in the area was consulted. Two reviewers blindly and independently conducted the selection, data extraction, and analysis of the risk of bias, the certainty of the evidence, and good psychometric measures. A meta-analysis was performed with a random effects model using the JAMOVI 2.3.2 software. RESULTS: Forty-nine studies were analyzed. In risk of bias assessment, the studies were classified as having inadequate structural validity and very good internal consistency. The analysis of good psychometric properties indicated indeterminate structural validity and insufficient internal consistency. The overall value of Cronbach's alpha was estimated at 0.94, thus suggesting a very good internal consistency. However, there was high heterogeneity. The level of certainty of the evidence was too low for internal consistency. CONCLUSION: The VHI proved to be a consistent and reliable patient-reported outcome measure to evaluate voice handicap in individuals with dysphonia; however, studies are heterogeneous, and the certainty of evidence is very low.

Prevalence of voice handicap among nurses in intensive care units due to occupational noise during pandemic.

Background: Healthcare workers have been identified as being at risk of occupational voice disorders. Among them, nurses working in intensive care units (ICUs) are particularly vulnerable due to the risk factors that are associated with their exposure to high levels of noise. Thus, this study aimed to determine the prevalence of voice disorders among ICU nurses. Methods: A questionnaire was administered to 100 ICU nurses from four hospitals in China. The questionnaire assessed vocal-related symptoms, perceived voice handicap, frequently heard noise sources, and the quality of communications. Results: Results indicate that the most frequently reported voice symptoms were 'voice tiredness' and 'voiceless'. Nurses working more than 50 h per week experienced voice symptoms more frequently than nurses working for 40-50 h per week. The median value of the perceived voice handicap score (VHI-30) was 23, indicating mild voice handicap, while 24% of the nurses reported severe voice handicap. Longer working hours and working at patient wards were significantly associated with higher VHI-30 scores. The nurses also reported that the quality of verbal communication with patients and colleagues and voice problems worsened during the COVID-19 pandemic. Conclusion: More than 20% of nurses reported severe voice handicap, however, voice handicap among ICU nurses did not appear universally to all nurses. Further research is necessary to identify the risk factors associated with voice disorders and the mechanism behind such heterogeneity among ICU nurses.

Reliability and validity of the Turkish voice handicap index-partner (VHI-P-TR).

OBJECTIVE: This study examines the Turkish validity, reliability and diagnostic performance of the Voice Handicap Index-Partner (VHI-P-TR), which is used to obtain the perceptions of communication partners of individuals with dysphonia about the functional, physical and emotional handicap resulting from the patient experiencing dysphonia. METHOD: The study included 160 individuals with dysphonia and their communication partners. First, translation, back translation, expert validity and pilot study were performed in the scale adaptation process. Then, a confirmatory factor analysis (CFA) was conducted to assess the construct validity of the VHI-P-TR. Correlations between the VHI-P-TR and Voice Handicap Index (VHI-TR) scores of dysphonic individuals were examined to evaluate the concurrent validity of the VHI-P-TR. To assess the reliability of the VHI-P-TR, a test-retest analysis was performed, and internal consistency coefficients (α) were calculated. A receiver operating characteristic (ROC) analysis was conducted to determine the cut-off point for the VHI-P scores. RESULTS: A high positive correlation was found between the participants' VHI-P-TR and VHI-TR total and subscales mean scores (r's > 0.782; p < 0.01). The VHI-P-TR had high internal consistency regarding for its subscales and total score (α's > 0.94; p < 0.01). Factor loadings of all VHI-P-TR items were higher than 0.30 and their error variances were lower than 0.90. In addition, factor loadings were statistically significant for all the items (p < 0.05). The data fit the model well according to all CFA indices except for GFI (scale = 0.69). An adequate sensitivity and specificity were achieved for the VHI-P-TR, and the cut-off point was found as 11.50 for the total score and ranged from 2.50 to 5.50 for the subscales. CONCLUSION: The VHI-P-TR is a valid and reliable measurement tool with high diagnostic performance in all subscales and total score, and has high levels of agreement with the VHI-TR.

Vocal health of parents of children with hearing assistive devices.

Background & Objectives: VH (Vocal health) is the need of the hour. VH of parents of children with hearing assistive devices (HAD) reveals a literature gap, during the habilitation process of their children. To explore the vocal health of parents of children with hearing assistive devices. Methods: This cross-sectional study was conducted at Riphah International University from September to December 2021. Study recruited N=384 parents of Hearing Impaired children (HIC) using HAD for at least two years, of both genders and aged 2-9 years using convenience sampling. Voice-related quality of life (V-RQOL), and vocal health Index (VHI) -10 were used for data collection. Data was analyzed on SPSS Version 25. Descriptive statistics, Anova and t-test were utilized to see difference between means of groups. P<0.05 shows significant-results. Results: Parents of children using hearing assistive devices had excellent V-RQOL score in 350(91.14%) parents. There was no significant difference in V=RQOL as regards type of hearing assistive device use (p=0.102), laterality of device use (p=0.918) and degree of hearing loss (p=0.143). However, type of hearing loss revealed significant difference (p=0.021). Also VHI score revealed significantly (p=0.008) lower means in parents of children with cochlear implants. Conclusion: Current study concludes that the parents raising hearing impaired children with hearing assistive devices, possess good vocal health as determined by VHI and V-RQOL scores with only a very small number of parents reporting vocal symptoms.
