University of California Los Angeles Dizziness Questionnaire

Acronym:

UCLA-DQ

Purpose:

Designed by Honrubia et al., (1996), The University of California Los Angeles Dizziness Questionnaire (UCLA-DQ) was designed to collect information on the severity, frequency and fear of dizziness and its effect on quality of life and activities of daily living.  The goal in the tool development was to develop a tool that was easy to understand, quick to administer and that was equally applicable to all dizzy patients.  The tool was designed to provide the clinician significant information about the impact of dizziness on the patient's life.  The tool was designed as a screening tool that provides clear, concise information in regards to the impact that dizziness has on an individual's everyday life.  The UCLA-DQ is designed to address the physical, emotional and functional aspects of dizziness in a five question,  easy to administer, easy to interpret questionnaire

Description:

The UCLA-DQ is a five item forced-choice, self-report subjective questionnaire.  The five questions measure dizziness frequency, severity, fear and impact on quality of life and activities of daily living.  The answer choices on the 5-point Likert scale are presented in ascending order from 1, indicating least severe, to 5, indicating most severe.  The score ranges from 5-25 with higher scores indicating most severity.

If an individual does not have dizziness at all, 0 points are given.

Test-retest Reliability:

Not Established for the original version; (Kammerlind et al., 2011) Test-retest reliability (ICC, 0.089) in subjects with remaining symptoms after AUVL in the Swedish translation version of the scale. (Perez et al., 2001) Cronbach's ɑ = 0.8236 for the Spanish version of the questionnaire

Internal Consistency:

Criterion Validity (Predictive/Concurrent):

Not Established

Construct Validity (Convergent/Discriminant):

(Perez et al., 2001) A significant relationship (p < 0.01) was found between item one, frequency of dizziness, item two, severity of dizziness and the other 3-items on the questionnaire. Factor analysis identified a two-factor solution for the UCLA-DQ that accounts for 75.43% of the variance Excellent correlation between vestibular handicap factor and DHI emotional (DHIe) subscale r = 0.927 p < 0.001, and DHI functional subscale (DHIf) r = 0.743 p < 0.001. Adequate correlation between vestibular handicap factor and the DHI physical (DHIp) subscale r = 0.317 p < 0.001 Excellent correlation between vestibular disability factor and the DHI emotional r = 0.912 p  < 0.001 Poor correlation between vestibular disability factor and the DHIf subscale 0.425 p < 0.001 Adequate correlation between vestibular disability factor and DHI physical subscale r = 0.714 p < 0.001
