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.

Abstract
OBJECTIVES Evaluate the measurement properties of the Dizziness Handicap Inventory (DHI) using item response theory in patients diagnosed with vestibular migraine (VM) and Meniere's disease (MD). DESIGN One hundred twenty-five patients diagnosed with VM and 169 patients diagnosed with MD by a vestibular neurotologist according to the Bárány Society criteria in two tertiary multidisciplinary vestibular clinics and who completed the DHI at their initial visit, were included in the study. The DHI (total score and individual items) was analyzed using the Rasch Rating Scale model for patients in each subgroup, VM and MD, and as a whole group. The following categories were assessed: rating-scale structure, unidimensionality, item and person fit, item difficulty hierarchy, person-item match, and separation index, standard error of measurement, and minimal detectable change (MDC). RESULTS Patients were predominantly female (80% of the VM subgroup and 68% of the MD subgroup) with a mean age of 49.9 ± 16.5 years and 54.1 ± 14.2 years, respectively. The mean total DHI score for the VM group was 51.9 ± 22.3 and for the MD group was 48.5 ± 26.6 ( p > 0.05). While neither all items nor the separate constructs met all criteria for unidimensionality (i.e., items measuring a single construct), post hoc analysis showed that the all-item analysis supported a single construct. All analyses met the criterion for showing a sound rating scale and acceptable Cronbach's alpha (≥0.69). The all-item analysis showed the most precision, separating the samples into three to four significant strata. The separate-construct analyses (physical, emotional, and functional) showed the least precision, separated the samples into less than three significant strata. Regarding MDC, the MDC remained consistent across the analyses of the different samples; approximately 18 points for the full analyses and approximately 10 points for the separate construct (physical, emotional, and functional). CONCLUSIONS Our evaluation of the DHI using item response theory shows that the instrument is psychometrically sound and reliable. The all-item instrument fulfills criteria for essential unidimensionality but does seem to measure multiple latent constructs in patients with VM and MD, which has been reported in other balance and mobility instruments. The current subscales did not show acceptable psychometrics, which is in line with multiple recent studies favoring the use of the total score. The study also shows that the DHI is adaptable to episodic recurrent vestibulopathies. The total score shows better precision and separation of subjects in up to four strata compared to the separate construct that separate subjects into less than three strata. The measurement error smallest detectable change was found in our analysis to be 18 points, which means any change in the DHI of less than 18 points is not likely to be clinically significant. The minimal clinically important difference remains indeterminate.

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.

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.

Front Aging Neurosci 2021; 13:667608. [PMID: 34177553 PMCID: PMC8232053 DOI: 10.3389/fnagi.2021.667608] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Accepted: 05/11/2021] [Indexed: 12/15/2022] Open
Abstract
Aging affects the vestibular system and may disturb the perception of verticality and lead to increased visual dependence (VD). Studies have identified that abnormal upright perception influences the risk of falling. The aim of our study was to evaluate subjective visual vertical (SVV) and VD using a mobile virtual reality-based system for SVV assessment (VIRVEST) in older adults with falls and evaluate its relationship with clinical balance assessment tools, dizziness, mental state, and depression level. This study included 37 adults >65 years who experienced falls and 40 non-faller age-matched controls. Three tests were performed using the VIRVEST system: a static SVV, dynamic SVV with clockwise and counter-clockwise background stimulus motion. VD was calculated as the mean of absolute values of the rod tilt from each trial of dynamic SVV minus the mean static SVV rod tilt. Older adults who experienced falls manifested significantly larger biases in static SVV (p = 0.012), dynamic SVV (p < 0.001), and VD (p = 0.014) than controls. The increase in static SVV (odds ratio = 1.365, p = 0.023), dynamic SVV (odds ratio = 1.623, p < 0.001) and VD (odds ratio = 1.460, p = 0.010) tilt by one degree significantly related to falls risk in the faller group. Fallers who had a high risk of falling according to the Tinetti test exhibited significantly higher tilts of dynamic SVV than those who had a low or medium risk (p = 0.037). In the faller group, the increase of the dynamic SVV tilt by one degree was significantly related to falls risk according to the Tinetti test (odds ratio = 1.356, p = 0.049). SVV errors, particularly with the dynamic SVV test (i.e., greater VD) were associated with an increased risk of falling in the faller group. The VIRVEST system may be applicable in clinical settings for SVV testing and predicting falls in older adults.
