OBJECTIVE: To investigate the distribution, internal consistency reliability, and
convergent and discriminant validity of the World Health Organization Quality of
Life Scale Brief Version (WHOQOL-BREF) in persons with mild to moderate Parkinson
disease (PD). DESIGN: Cross-sectional. SETTING: Movement disorders center.
PARTICIPANTS: Convenience sample of people with PD (n=96) recruited from a
movement disorders center and controls (n=60) recruited from the community
(N=156). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: WHOQOL-BREF.
RESULTS: The WHOQOL-BREF domain data were relatively normally distributed, and
internal consistency reliability was acceptable (alpha=.65-.85). Participants
with PD reported lower quality of life (QOL) than controls in all except the
environment domain, and physical QOL was the most impaired domain in the PD
group. Age, fatigue, and physical activity limitations predicted physical QOL;
depression, fatigue, and apathy predicted psychological QOL; education, executive
dysfunction, and apathy predicted social QOL; and age, education, depression, and
apathy predicted environment QOL. CONCLUSIONS: The WHOQOL-BREF is a suitable tool
to assess QOL in patients with mild to moderate PD. It is relatively normally
distributed and internally consistent; effectively discriminates between
individuals with and without PD; and correlates with relevant demographic
characteristics, PD-related impairments, and activity limitations.
