Cost Description

Paper copies of short forms are available. PDFs can be requested through emails to sci-qol@udel.edu and tbi-qol@udel.edu

Electronic versions can be found in the NIH Toolbox or the PROMIS app. Either app is $500/yr, and covers up to 10 iPads on a single license. The SCI-QOL and TBI-QOL CATs can be administered directly through these apps. It is important to note that using the app requires you to be physically with the participant or read the questions aloud by interview over the phone - there is no way to send a link to have someone complete the measures at home.

Free electronic versions are available. If your institution has REDCap, the CATs and short forms can be accessed through the REDCap instrument library by searching for the specific measure you want and adding them to your REDCap project. For non-REDCap alternatives, the SCI-QOL and TBI-QOL short forms can be imported into an alternative electronic administration platform such as Qualtrics, SurveyMonkey, Google Forms, etc. Email sci-qol@udel.edu or tbi-qol@udel.edu to request PDF versions.

Diagnosis/Conditions

Spinal Cord Injury

Spinal Injuries

The SCI-QOL Basic Mobility measure is an item response theory (IRT)-calibrated item bank with 56 items that is available for administration as a computer adaptive test (CAT; range 4-12 items) or 10 item short form (SF).

Number of Items

Short: 10

CAT: 4-12

The short form requires the form and a pencil.

Standard Error of Measurement (SEM)

Depends on mode of administration and injury type:

Manual Wheelchair

10-item short form for Tetraplegia: SEM= 2.12
10-item short form for Paraplegia: SEM= 1.70

Power Wheelchair

10-item short form for Tetraplegia: SEM= 1.00
10-item short form for Paraplegia: SEM= 0.80

Minimal Detectable Change (MDC)

Calculated from SEM:

Manual Wheelchair

10-item short form for Tetraplegia: MDC= 5.87
10-item short form for Paraplegia: MDC= 4.70

Power Wheelchair

10-item short form for Tetraplegia: MDC= 2.77
10-item short form for Paraplegia: MDC= 2.22

Cut-Off Scores

Traumatic SCI:

Power Wheelchair

≤15: Few basic wheelchair activities
16-40: Some wheelchair activities
41-52: All wheelchair activities
53-63: No difficulty with any activities
≥64: Not Applicable

Manual Wheelchair

≤15: No wheelchair activities
16-40: Unable to do most wheelchair activities
41-52: Some basic wheelchair activities
53-63: Most wheelchair activities
≥64: All wheelchair activities

Normative Data

Traumatic SCI: The normative data are calibrated on adults with traumatic spinal cord injury. The mean score (T = 50) indicates a score that is normal for an adult with a traumatic SCI. (Sinha et al., 2015; n = 855, mean age = 43.1 years (15.3); time post injury = 6.8 years (9.3); 54% paraplegia, 46% tetraplegia)

Test/Retest Reliability

Traumatic SCI: (Heinemann et al., 2014; n = 855)

Manual Wheelchair

Excellent: (ICC = 0.98 for tetraplegia; ICC = 0.97 for paraplegia)

Power Wheelchair

Excellent: (ICC = 0.99 for tetraplegia and paraplegia)

Criterion Validity (Predictive/Concurrent)

Traumatic SCI: (Sinha et al., 2015; n = 269; mean age = 43.8 years (15.5); time post injury = 6.8 (8.7); 46.5% paraplegia; 52.4% tetraplegia)

Adequate concurrent validity with:

Functional Index Measure: ρ = 0.644

Floor/Ceiling Effects

Traumatic SCI: (Heinemann et al., 2014)

Manual Wheelchair

Floor Effect: Adequate (3% for tetraplegia) Excellent (0% for paraplegia)
Ceiling Effect: Adequate (1% for tetraplegia; 2% for paraplegia)

Power Wheelchair

Floor Effect: Adequate (1% for tetraplegia and paraplegia)
Ceiling Effect: Adequate (3% for tetraplegia; 21% for paraplegia)
