Development of an inventory for dizziness and related factors

Abstract

Dizziness is an extremely common complaint of patients, yet often goes unexplained after medical evaluation, which can lead to inappropriate treatment. There is a lack of psychometrically sound self-report instruments that measure dizziness and related factors. This study describes the application of factor analytic procedures with 184 dizzy patients' responses to develop the Dizzy Factor Inventory (DFI), a 44-item inventory divided into three sections and modeled after the Multidimensional Pain Inventory. The first section consists of symptom factors, the second concerns responses of significant others to the dizzy patient, and the third section assesses activity level. This inventory groups symptoms into empirically distinct factors that could be related in clinical and research applications to physiological and psychological processes, and could be useful for treatment planning and measuring treatment progress. Factors derived with dizzy patients are compared to factors found with chronic pain patients.

Literature Review of Questionnaires Assessing Vertigo and Dizziness, and Their Impact on Patients' Quality of Life

“…Table 2 presents the 10 questionnaires identified in the 29 articles: four QoL or handicap [1,11–25], three mixed [5,26,27], and two symptomatic [2,28–33] questionnaires were identified plus one Meniere's disease‐specific questionnaire [34,35]. Validation scores obtained from the PRO‐specific checklist (Table 1) ranged between 36 and 77 (Fig.…”

Top-down approach to vestibular compensation: Translational lessons from vestibular rehabilitation

“…This perception is sufficiently prevalent and robust that impaired ability for concentration, attention and/or memory meets statistical criteria for inclusion in the Dizziness Handicap Inventory (DHI) and related questionnaire instruments for subjective impairment (Hazlett et al, 1996; Jacobson and Newman, 1990; Morris et al, 2008; Morris et al, 2009; Yardley et al, 1992). However, this item is far from a specific or sensitive detector of cognitive function.…”
