Correlates of a Single-Item Quality-of-Life Measure in People Aging with Disabilities

Area of Science:

• Rehabilitation Medicine
• Disability Studies
• Psychometrics

Background:

• Quality of life (QOL) is crucial for individuals with disabilities.
• Existing QOL screening methods may not adequately capture patient-centered concerns.
• Need for practical tools to guide clinical decisions in disability care.

Purpose of the Study:

• To evaluate the utility of the Kemp Quality of Life Scale for assessing QOL in adults with diverse disabilities.
• To determine the relationship between QOL and clinical variables such as functional level, depression, and social interaction.

Main Methods:

• Secondary analysis of a large dataset of adults with cerebral palsy, polio, rheumatoid arthritis, and stroke.
• Utilized the single-item, seven-point Kemp Quality of Life Scale to measure QOL.
• Compared clinical characteristics across low, average, and high QOL subgroups using ANOVA and Tukey's HSD tests.

Main Results:

• Low QOL scores were significantly associated with lower functional levels, higher depression, and reduced social interaction across all disability groups (P < 0.001).
• High QOL scores were significantly correlated with higher social interaction (P < 0.001).
• QOL subgroups were comparable in age, sex, and disability duration within each diagnostic group.

Conclusions:

• The Kemp Quality of Life Scale demonstrates significant associations with key clinical variables in adults with impairments.
• The scale shows potential as a practical tool for direct clinical care and decision-making.
• Further research is warranted to explore the scale's application in routine clinical practice.
