Link to instrument: CATs and short forms available at http://ift.tt/1hR3vma (request access through SCI-QOL@udel.edu). Item bank and short form PDFs available through SCI-QOL@udel.edu.

Acronym:

SCI-QOL Bladder Management Difficulties

Purpose:

The SCI-QOL Bladder Management Difficulties instrument assesses difficulties associated with bladder management in individuals with spinal cord injury (SCI).

Description:

The SCI-QOL Bladder Management Difficulties measure is an item response theory (IRT)-calibrated item bank with 15 items that is available for administration as a computer adaptive test (CAT; range 4-12 items) or 8 item short form (SF).

Area of Assessment: Incontinence, Quality of Life

Body Part: Not Applicable

ICF Domain: Body Function

Domain: General Health

Assessment Type: Patient Reported Outcomes

Length of Test: 05 Minutes or Less

Time to Administer:

<5 Minutes

Number of Items: There are 15 items in the entire item bank. The short form has 8 items. The CAT can present 4-12 items, depending on the user's time vs. accuracy preferences.

Equipment Required:

The Short Form (SF) version requires only the printed form and a pencil. A CAT administration requires a desktop, laptop, or tablet computer with internet connection and login to AssessmentCenter.net.

Access to the short form, and administration of CATs through Assessment Center, is available through SCI-QOL@udel.edu.  

Training Required: Yes. SCI-QOL Bladder Management Difficulties article (Tulsky et al., 2015) and, if administering CATs, the Assessment Center User Manual.

Type of training required: Reading an Article/Manual

Cost: Free

Actual Cost:

Free

Age Range: Adult: 18-64 years, Elderly adult: 65+

Administration Mode: Computer

Diagnosis: Spinal Cord Injury

Populations Tested:

Spinal Cord Injury

Standard Error of Measurement (SEM):

Depends upon mode of administration:

• Full Item Bank: Mean SEM= 3.45 (Range= 1.5-6.3)
• 8-Item Short Form: Mean SEM= 4.21 (Range= 1.9 - 6.4)
• 8-Item Fixed CAT: Mean SEM= 0.38 (Range= 0.17-0.64)
• Variable Length CAT (Min 8): Mean SEM= 0.36 (range= 0.17 - 0.63)
• Variable Length CAT (Min 4): Mean SEM= 0.37 (0.21-0.63)

Minimal Detectable Change (MDC):

Calculated Using Mean SEM:

• Full Item Bank: MDC= 12.41
• 8-Item Fixed CAT: MDC= 12.3
• Variable Length CAT: MDC= 12.36

Minimally Clinically Important Difference (MCID):

Not Established

Cut-Off Scores:

Not Established

Normative Data:

 

Test-retest Reliability:

Traumatic SCI (Tulsky et al., 2015)

• Excellent: (Pearson's r= 0.77)
• Excellent: (ICC= 0.76)

Interrater/Intrarater Reliability:

Not Applicable

Internal Consistency:

Traumatic SCI (Tulsky et al., 2015)

• Full Item Bank: Excellent (Cronbach's Alpha= 0.91)

Criterion Validity (Predictive/Concurrent):

Not Established

Construct Validity (Convergent/Discriminant):

Not Established

Content Validity:

Items were derived from focus groups and interviews with individuals with traumatic SCI and clinicians who specialize in SCI care (Tulsky et al., 2011).

Face Validity:

Not statistically assessed, but content was generated from individuals with SCI and expert clinicians, so face validity is believed to be strong.

Floor/Ceiling Effects:

Traumatic SCI(Tulsky et al., 2015)

 

Variable-length CAT (Min 4):

• Floor Effect: Adequate (17.4%)
• Ceiling Effect: Excellent (0.13%)

Variable-length CAT (Min 8):

• Floor Effect: Adequate (17.4%)
• Ceiling Effect: Excellent (0.13%)

8-Item Fixed-length CAT:

• Floor Effect: Adequate to Excellent (4.5%)
• Ceiling Effect: Excellent (0.13%)

8-Item Short Form:

Floor Effect: Poor (30.7%)

Ceiling Effect: Excellent (0.13%)

Full Item Bank:

• Floor Effect: Adequate (13.3%)
• Ceiling Effect: Excellent (0.13%)

Responsiveness:

Not Established

Considerations:

None
