The Rasch analysis results suggest that the KDHI is a reliable scale for measuring the imbalance symptoms in PD patients, and identified parts for possible amendments in order to further improve the linear metric scale. Short form of the Dizziness Handicap Inventory: construction and validation through Rasch analysis. There was no statistical evidence of disorder in polytomous rating scales. CONCLUSIONS: The KDHI provide unidimensional measures of imbalance symptoms in patients with PD with adequate separation reliability. However, the KDHI showed several issues for inappropriate scale targeting and misfit items (items 1 and 2) for Rasch model. Results were statistically analyzed with the program Microsoft Excel. The KHDI had satisfactory PSR and there were no disordered thresholds in the 3-point rating scale. RESULTS: Principal component analyses of residuals revealed that the KDHI had unidimensionality. The separation reliability of the KDHI was assessed based on person separation reliability (PSR), which is used to measure the capacity to discriminate among groups of patients with different levels of balance deficits. The utilities of the orderedresponse categories of the 3-point Likert scale were analyzed with reference to the probability curves of the response categories. METHODS: The unidimensionality, scale targeting, separation reliability, item difficulty (severity), and response category utility of the KDHI were statistically assessed based on the Andrich rating scale model. The aim of our study was to address the feasibility and clinimetric properties of the KDHI instrument using polytomous Rasch measurement analysis. The DHI is a 25-item self-assessment inventory designed to evaluate the self-perceived handicapping effects imposed by dizziness. Nevertheless, few studies have examined the KDHI based on item-response theory within this population. The DHI is highly correlated with patients' psychological status.ĭHI migraine positional vertigo psychogenic dizziness vertigo vestibular dysfunction.ABSTRACT OBJECTIVES: The Korean Dizziness Handicap Inventory (KDHI), which includes 25 patient-reported items, has been used to assess self-reported dizziness in Korean patients with Parkinson disease (PD). The positional subscale showed the highest scoring in the BPPV group with high sensitivity and low specificity of the test. Dizziness Handicap Inventory (DHI), Julia Treleaven. (4) Conclusions: Our analysis revealed that the DHI vestibular subscale distinguishes between patients with compensated and uncompensated vestibular dysfunction. Dizziness Using Dizziness Handicap Inventory in the Patients with Benign Paroxismal Positional Vertigo. Excel 2010 (Microsoft, Redmond, WA, USA). The DHI total score and the subscales scores correlated with anxiety-depression, and the highest correlation coefficients were calculated for vestibular (F2 0.56) and anxiety (F5 0.51) subscales. The secondary outcomes were the dynamic gait index (DGI) and the dizziness handicap inventory (DHI). The DHI items composing the F3 (positional) subscale revealed the highest scoring in the BPPV group with 75% sensitivity and 92% negative predictive value (NPV) in reference to Dix-Hallpike tests. For this test we ask the patient to follow some moving lights with their eyes. (3) Results: The DHI questionnaire total scoring and its vestibular subscale distinguished between patients with compensated and uncompensated vestibular dysfunction with positive predictive values of 76% and 79%, respectively. Diagnostic Testing We offer the following diagnostic testing including: Videonystagmography/Electronystagmography (VNG/ENG) This test tells us, among other things, whether both inner ears of balance are equally strong. Principal component analysis was used to examine the factorial structure of the questionnaire. (2) Material and methods: This observational study included 343 dizzy patients with one of the following clinical conditions: Vestibular impairment noncompensated or compensated, central or bilateral, benign paroxysmal positional vertigo (BPPV), migraine and psychogenic dizziness. Objective:This study was designed to observe the dizziness handicap inventory (DHI) scores in patients with BPPV (benign paroxysmal positional vertigo) before and after maneuver repositioning and aimed to discuss the values of DHI scores in the diagnosing and treatment of BPPV. The aim of this study was to identify the subscales of DHI that may correlate with some vestibular or nonvestibular dysfunctions. The Dizziness Handicap Inventory (DHI) is widely used in the assessment of dizziness-related disability, but its clinical efficacy needs further expansion. (1) Objectives: The evaluation of dizzy patients is difficult due to nonspecific symptoms that require a multi-specialist approach.
