Abstract
Objective This study aimed to establish and validate a Jordanian Arabic version of the Dizziness Handicap Inventory (DHI-JA) equivalent to the original DHI in English (DHI-E). Methods The THI-E questionnaires were translated into formal Jordanian Arabic by two bilingual volunteer audiologists. The final version, curated by the author, was administered to 20 participants with normal balance and 64 patients experiencing dizziness at the Middle East Hearing and Balance Centre. Results The results demonstrated excellent internal consistency and reliability of DHI-JA. A highly significant correlation was observed between the total scores and sub-scores of DHI-JA and DHI-E. Conclusion This study concludes that the DHI-JA is a valid and reliable tool for assessing the severity of dizziness and balance disorders in the Jordanian Arabic-speaking population.

[PMID: 38150920 DOI: 10.1016/j.vhri.2023.10.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 09/26/2023] [Accepted: 10/31/2023] [Indexed: 12/29/2023]
Abstract
OBJECTIVES The Dizziness Handicap Inventory (DHI) is the most popular and widely used questionnaire in evaluating patients with vertigo. This questionnaire has a screening version with a high correlation with DHI. This study aimed to assess the psychometric properties of the Persian DHI - Screening version (DHI-S). METHODS This cross-sectional and methodological study was conducted on 300 patients at the central vestibular clinic in Mashhad, Iran, from 2020 to 2021. First, the DHI-S was translated into Persian using the backward-forward translation method. Subsequently, the following types of validity and reliability were examined: content validity based on content validity index and content validity ratio, face validity based on impact score, construct validity based on confirmatory factor analysis, internal consistency based on Cronbach's α and Ω, and test-retest stability based on intraclass correlation coefficient and smallest detectable change. RESULTS The DHI-S had high content and face validity. Score 8 was selected for the cutoff point between patients and the normal group with a sensitivity of 63.67% and specificity of 96.08%. The construct validity indicated that the questionnaire is one-dimensional. The Cronbach's α and Ω for internal consistency were 0.855 and 0.851, respectively. The intraclass correlation coefficient was 0.981 and the smallest detectable change was 5.521. CONCLUSIONS The DHI-S in the Persian language has high and acceptable psychometric properties. This questionnaire can be used in research and clinical settings.

A cross-sectional study. J Neurol Sci 2023; 445:120547. [PMID: 36634581 DOI: 10.1016/j.jns.2023.120547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 01/04/2023] [Accepted: 01/04/2023] [Indexed: 01/09/2023]
Abstract
OBJECTIVES Peripheral vestibular disorders except from reflexes dysfunction correspond also to cognitive decline. The objectives of this cross-sectional study were to a) identify correlations among variables of functional gait, cognitive function, and perceived dizziness and b) explore variables that could be used as prognostic factors of functional gait in people with peripheral vestibular deficits. METHODS We recruited 154 people with peripheral vestibular deficits. The participants presented with moderate disability in terms of the Dizziness Handicap Inventory questionnaire (mean: 48.00, 95% confidence interval: 45.24-50.75), deficits in the Functional Gait Assessment test (mean: 22.75, 95% confidence interval: 22.13-23.40) and indication of mild cognitive impairment based on Montreal Cognitive Assessment tool (mean: 25.18, 95% confidence interval: 24.75-25.60). RESULTS Statistically significant correlations found among functional gait and gender, age, educational level, perceived level of disability and the total score of the Montreal Cognitive Assessment tool. Several components of the cognitive screening test (executive function, vigilance, language skills, verbal fluency) also correlated statistically significant with functional gait. Linear regression models revealed that age, perceived level of disability and vigilance significantly predicted functional gait variability (R2 = 0.350; p < 0.001) as well as high risk of falling, as indicated by a score on Functional Gait Assessment test <22/30 (R2 = 0.380). CONCLUSIONS Cognitive impairments affect functional gait in people with peripheral vestibular disorders. Thus, the integration of cognitive functional assessment must be considered as a prerequisite for functional assessment and designing rehabilitation programs that will include dual task training.

Abstract
OBJECTIVES The Dizziness Handicap Inventory (DHI) questionnaire is used to assess the severity of vertigo. In clinical practice, it is a good indicator for understanding the patient's feelings and can be used as a quantitative measure for monitoring ongoing treatment and rehabilitation. This study involved the translation, cultural adaptation, and validation of the Polish DHI questionnaire (DHI-POL). METHODS We recruited 127 subjects (mean age 55.1 years) who experienced vertigo, dizziness, and imbalance resulting from a disturbance to their vestibular system that had lasted longer than 1 month and 56 subjects (mean age 51.8 years) without any vestibular symptoms. All subjects performed a posturography Sensory Organization Test and completed the questionnaire twice. RESULTS Cronbach's alpha for the overall DHI-POL was α = 0.93. The questions were divided into 3 subgroups (functional [F], emotional [E], and physical [P]) for which the internal consistency was as follows: DHI-F, α = 0.84; DHI-E, α = 0.85; and DHI-P, α = 0.81. Reproducibility, as measured by interclass correlation coefficient for the overall DHI-POL, was 0.91. For each interclass correlation coefficient subgroup, the results were as follows: DHI-F, 0.90; DHI-E, 0.93; and DHI-P, 0.83. CONCLUSIONS DHI-POL has a high consistency and repeatability; therefore, it is a fully functional questionnaire that meets all the validation criteria and is a tool ready for use on Polish patients with vertigo.

Abstract
OBJECTIVE To translate and evaluate psychometric properties of Thai version of the Dizziness Handicap Inventory (DHI-TH). STUDY DESIGN A cross-sectional study. SETTING Ambulatory. PATIENTS Fifty patients with dizziness at a vestibular clinic. MAIN OUTCOME MEASURES Translation and cross-cultural adaptation of the original English version of the DHI was performed according to published guidelines. Psychometric evaluation included internal consistency, content validity, test-retest reliability, convergent validity, discriminant ability, and responsiveness. Responsiveness was examined in 28 patients with vestibular dysfunction who received vestibular rehabilitation for 6 to 8 weeks. RESULTS There were no floor and ceiling effects. The Cronbach's alpha was good for the total score (0.87) and subscale scores (0.70 physical, 0.73 emotional, and 0.71 functional). Excellent test-retest reliability was demonstrated for the total and subscales (ICC ranged from 0.91 to 0.97, p < 0.001). The SEM was 3.50 and the MDC was 9.68. The total and subscales of DHI-TH were moderately correlated with the SF-36-TH scores (r ranged from -0.40 to -0.63). An optimal cut-off point for detection of dizziness was 21 points (98% sensitivity, 94% specificity). Responsiveness of the DHI-TH was excellent. The ES and SRM were large (1.25 and 1.59, respectively). The DHI-TH discriminated well between patients with self-perceived improved dizziness versus unchanged dizziness (AUC = 0.87). The MCID was 17 points (82.0% sensitivity, 82.0% specificity). CONCLUSION The DHI-TH demonstrated good psychometric properties for patients with dizziness. The DHI-TH is a valid and reliable instrument recommended as a measure of disability and quality of life in Thai patients with dizziness.

Abstract
PURPOSE To provide physicians and patients with the tools needed to evaluate patients' problems and health-related quality of life by cross-culturally adapting and validating the Chronic Otitis Media Questionnaire 12 (COMQ-12), the Dizziness Handicap Inventory (DHI), the Neuropsychological Vertigo Inventory (NVI) and the Tinnitus Handicap Inventory (THI). MATERIALS AND METHODS COMQ-12, DHI, NVI and THI were translated into the Slovenian language and completed by patients treated at our department for chronic otitis media, vertigo or tinnitus. The control group for each questionnaire consisted of healthy volunteers. Internal consistency, test-retest reliability, discriminant validity, diagnostic accuracy and cut-off value were determined for each questionnaire. RESULTS Test-retest reliability was excellent for DHI (ICC A=0.946) and NVI (p=0.315, ICC A=0.975), good to excellent for COMQ-12 (p=0.680, ICC A=0.858) and satisfactory for THI (p=0.120). Discriminant validity was confirmed for each questionnaire (p>0.05) using the Mann-Whitney U test (COMQ-12, DHI, THI) or the Welch t-test (NVI). COMQ-12 had acceptable (α=0.796) and DHI (α=0.910), NVI (α=0.950) and THI (α=0.924) perfect internal consistency. COMQ-12 and DHI had excellent, NVI acceptable and THI perfect diagnostic accuracy (AUC=0.987, AUC=0.999, AUC=0.781 and AUC=1.000 respectively). Cut-off values determined by Youden's index were 7, 7, 9 and 56 for COMQ-12, THI, DHI and NVI, respectively. CONCLUSION Slovenian COMQ-12, DHI, NVI and THI are a valid and accurate tool for the diagnosis and measurement of health-related quality of life in patients with chronic otitis media, vertigo and tinnitus. They could aid general practitioners, occupational health specialists, neurologists and otorhinolaryngologists.

Abstract
OBJECTIVE The Dizziness Handicap Inventory (DHI) is a 25-item self-report questionnaire developed to measure the disabling and handicapping impact of dizziness. The present investigation was conducted in an effort to re-assess the factor structure of the DHI. STUDY DESIGN Retrospective study. SETTING Tertiary care center. PATIENTS Subjects were 1,991 patients who were evaluated in the Mayo Clinic-Rochester Vestibular and Balance Laboratory. MAIN OUTCOME MEASURES Exploratory factor analysis: an exploratory bifactor analysis (EFA) with bifactor rotation was used to analyze a random sample of 999 patients. Analyses were used to determine the dominance of the general factor (i.e., total score) relative to the group factor (i.e., subscales). Confirmatory factor analysis: a confirmatory bifactor graded response model was fit with appropriate item-to-group relationships that was discovered by our exploratory analyses. To validate the bifactor model that was identified with the exploratory analyses, a bifactor model with three grouping factors (i.e., Physical manifestations, Catastrophic impact of dizziness, and the Emotional impact of dizziness) were fit to a different random sample of 992 patients using the new item-to-group factor specifications. RESULTS In the confirmatory analyses, all items had a positive factor loading on the general factor. There were 14 items that loaded on the general factor only. The rest of the items (n = 11) loaded on both the general factor and one of three group factors. CONCLUSIONS Conclusions of the study revealed several findings: 1) reporting the result as a total score (i.e., a single general factor) is warranted, and, 2) there is statistical support for the existence of three subscales representing: the Physical manifestations, Catastrophic impact, and Emotional impact of dizziness and vertigo.

Abstract
We cross-culturally adapted the Dizziness Handicap Inventory (DHI) into Central Kurdish dialect (DHI−CK) and verified its reliability and validity. A cross-sectional study was utilised to measure the impacts of vestibular disorders. Along with the DHI−CK, two comparators were introduced: the Visual Analogue Scale and the Clinical Test of Sensory Interaction and Balance. External and internal reliability were tested with intraclass correlation coefficient (ICC) and Cronbach’s alpha/composite reliability, respectively. Patients (n = 301; mean age = 44.5 ± 15.2 years; 59.8% women) presenting with vestibular symptoms for at least 30 days who were diagnosed with a vestibular disorder and healthy participants (n = 43; mean age = 42 ± 17.9 years; 62.8% women) (N = 344). The DHI−CK and its three sub-scales—Physical, Emotional, Functional—exhibited good to excellent external reliability: ICCs in the test-retest were 0.93, 0.88, 0.91, and 0.92, respectively. Cronbach’s alphas were 0.87, 0.71, 0.75, and 0.73, respectively. Convergent validity was supported by Spearman’s correlations between the DHI−CK and the comparators. The receiver operating characteristic curve analysis confirmed discriminating validity. The DHI−CK was cross-culturally validated. It is a reliable and valid tool that can be used by clinicians and researchers to quantify vestibular disorder outcomes in Kurdish-speaking populations.
