The Progressive Supranuclear Palsy quality of life scale (PSP-QoL) has been shown to be a useful tool for capturing health-related quality of life of patients in “everyday life” and in progressive supranuclear palsy (PSP) research. However, at 45 items in length, the questionnaire can take a long time, exhausting PSP patients, in particular if cognitive impaired, which can have a negative impact on the assessment. The aim of this study was to establish a condensed version of the PSP-QoL for research and routine clinical care.
Methods
In this retrospective study, data originating from a German cohort of PSP patients was analyzed. Data from 245 PSP patients were included in this study. The short PSP-QoL questionnaire was created using a two-factor solution and item-total and inter-item correlations for mental and physical aspects of daily living of the PSP-QoL followed by confirmatory factor analysis.
Results
The final scale included 12 items representing mental (five items) and physical symptoms (seven items). The specified two-factor model displayed an excellent fit in the confirmatory factor analysis. The short Progressive Supranuclear Palsy Quality of Life scale (PSP-ShoQoL) correlated moderately with the PSP Rating Scale (r [243] = 0.514, P < 0.001) and Geriatric depression scale (r [231] = 0.548, P < 0.001). Sensitivity to change confirmed a significant decrease in QoL after 12 months.
