Quality of Life Index, Spinal Cord Injury Version

Last Updated

Purpose

The QLI was developed to measure quality of life in various populations by measuring both satisfaction with aspects of quality of life and importance of those aspects of quality of life. The QLI-SCI was developed to measure quality of life specifically in people with spinal cord injury.

Diagnosis/Conditions

  • Spinal Cord Injury

Key Descriptions

  • 32 items (generic Quality of Life Index) to 37 items (QLI-SCI).
  • Each item is rated on a scale of 1 (least satisfied/important) to 6 (most satisfied/important).
  • 5 scores of 0-30 (0 = less satisfied, 30 = most satisfied) are calculated:
    1) Total Quality of Life score
    2) Health and Functioning Subscale
    3) Social and Economic Subscale
    4) Psychological/Spiritual Subscale
    5) Family Subscale
  • QLI-SCI may be administered by interview or by self-report.
  • Calculation of score weighs satisfaction scores according to level of importance assigned to each item.
  • Administration and scoring instructions can be found at: http://www.uic.edu/orgs/qli/questionaires/pdf/spinalcordinjuryversionIII/scoring.pdf

Professional Association Recommendation

Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Non-Specific Patient Population

back to Populations

Test/Retest Reliability

Healthy Subjects:

(Ferrans & Powers, 1985; n = 88; mean age = 33.1(6.73); nursing graduate students) 

 

  • Excellent test-retest correlations of 0.87 on the generic version of the QLI

Internal Consistency

Healthy Subjects:

(Ferrans & Powers, 1985) 

 

  • Excellent internal consistency for the generic version of the QLI (Cronbach’s alpha = 0.93)

Criterion Validity (Predictive/Concurrent)

Concurrent Validity

Healthy Subjects:

(Ferrans & Powers, 1985) 

 

  • Excellent correlation between QLI (generic version) scores and generic life satisfaction question/rating (= 0.75)

Content Validity

Healthy Subjects:

(Ferrans & Powers, 1985) 

 

  • The generic version of the QLI was developed based on literature review of dimensions of quality of life.

Spinal Injuries

Construct Validity

Chronic SCI:

Convergent Validity

(May & Warren, 2002; n = 98; mean age = 45.2 years; mean time post-SCI = 15.5 years; cervical injury = 56.1%, thoracic/lumbar injury = 43.9%)

 

  • Excellent correlation between QLI-SCI and Reintegration to Normal Living Index (r = -0.654) and Rosenberg Self-esteem Scale (r = 0.609) 

 

Discriminate Validity

(May & Warren, 2002) 

 

  • Poor correlation between QLI-SCI and ASIA motor score (r = 0.058) and Functional Independence Measure (r = 0.202)

Face Validity

Chronic SCI:

(May & Warren, 2001; = 11; mean age = 33.1 years; mean time post-SCI = 10.5 years (range = 1.6-26.8 years); cervical injury = 8, thoracic/lumbar injury = 3) 

 

  • Revised/current version items and domains/subscales were validated by interview to determine items needing modification from the original version of the QLI-SCI
