A Short Progressive Supranuclear Palsy Quality of Life Scale

Area of Science:

• Neurology
• Quality of Life Assessment

Background:

• The 45-item Progressive Supranuclear Palsy Quality of Life scale (PSP-QoL) is valuable but lengthy, potentially exhausting patients.
• Cognitive impairment in PSP patients can negatively impact the assessment duration and quality.

Purpose of the Study:

• To develop a condensed version of the PSP-QoL for efficient research and clinical application.
• To create a shorter, reliable tool for assessing health-related quality of life in Progressive Supranuclear Palsy.

Main Methods:

• Retrospective analysis of data from 245 German Progressive Supranuclear Palsy patients.
• Development of a short PSP-QoL using a two-factor solution, item correlations, and confirmatory factor analysis.
• Validation against the PSP Rating Scale and Geriatric Depression Scale.

Main Results:

• A 12-item scale (PSP-ShoQoL) was finalized, comprising five mental and seven physical symptom items.
• The two-factor model showed excellent fit in confirmatory factor analysis.
• PSP-ShoQoL demonstrated moderate correlations with PSP Rating Scale (r=0.514) and Geriatric Depression Scale (r=0.548), and was sensitive to quality of life changes over 12 months.

Conclusions:

• The 12-item PSP-ShoQoL is a validated, condensed measure for assessing quality of life in Progressive Supranuclear Palsy.
• This shorter scale facilitates clinical work and research by providing a sensitive and reliable assessment tool.
• The PSP-ShoQoL aids in capturing the health-related quality of life experienced by PSP patients.
