Spinal Cord Injury – Quality of Life Anxiety

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 Anxiety

Purpose:

Assess symptoms of anxiety in individuals with spinal cord injury.

 

Description:

The SCI-QOL Anxiety measure is an item response theory (IRT)-calibrated item bank with 25 items that is available for administration as a computer adaptive test (CAT; range 4-12 items) or short form (SF). Many items are shared with the PROMIS (15 of 25 items) and Neuro-QOL (20 of 25 items) Anxiety item banks.

Area of Assessment: Mental Health, Negative Affect, Stress and Coping

Body Part: Not Applicable

ICF Domain: Body Function

Domain: Emotion

Assessment Type: Patient Reported Outcomes

Length of Test: 05 Minutes or Less

Time to Administer:

5 minutes

Number of Items: There are 25 items in the entire item bank. The short form has 9 items. The CAT can present 4-12 items, depending on the user's time vs. accuracy preferences.

Equipment Required:

The Short Form 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 Anxiety article (Kisala et al. 2015) and, if administering CATs, 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 on the mode of administration. The SEM of the full item bank is 0.22. The SEM of an 9-item fixed-length CAT is 0.29. The SEM of a variable-length CAT (min = 4, max = 12 items) is 0.32.

Minimal Detectable Change (MDC):

Calculated from SEM). The MDC of the full item bank is 0.51. The MDC of an 8-item fixed-length CAT is 0.63. The MDC of a variable-length CAT is 0.67

Minimally Clinically Important Difference (MCID):

Not Established

Cut-Off Scores:

Kisala et al. (2015) created a "cross-walk" table to transform SCI-QOL Anxiety scores to scores on the GAD-7, a gold standard measure of anxiety with well-established cut scores. The SCI-QOL Anxiety scores below are the equivalent of GAD-7 cutoff scores. • T49-T55: Mild anxiety • T56-61: Moderate anxiety • T62+ Severe anxiety

Normative Data:

General population (2000 U.S. Census). The normative data reference the calibration sample from PROMIS, which matches the demographics of the 2000 U.S. Census.

Test-retest Reliability:

Traumatic SCI (Kisala et al., 2015; n=716, mean age = 43.0(15.3); time post injury = 7.1 years (10.0); 45% paraplegia, 54% tetraplegia) Excellent test-retest reliability (ICC = .80)

Interrater/Intrarater Reliability:

N/A

Internal Consistency:

Traumatic SCI (Kisala et al., 2015) Excellent internal consistency (Cronbach's alpha = .95)

Criterion Validity (Predictive/Concurrent):

Traumatic SCI (Kisala et al., 2015) Excellent concurrent validity predicting the GAD-7 score (r = .67)

Construct Validity (Convergent/Discriminant):

Traumatic SCI (Tulsky et al., in preparation) The SCI-QOL Anxiety item bank demonstrated good convergent validity by correlating strongly with measures of depression (PHQ-9 r = .61), satisfaction with life (Satisfaction with Life Scale r = -.53), resilience (SCI-QOL Resilience r = -.68), and positive affect (SCI-QOL Positive Affect r = -.59). The SCI-QOL Anxiety item bank demonstrated good discriminant validity by not correlating with measures of fine motor functioning (SCI-QOL Fine Motor r = -.046),

 

Content Validity:

Some SCI-QOL items were derived from the focus groups and cognitive interviews that founded the PROMIS and/or Neuro-QOL measurement systems. The Neuro-QOL focus groups comprised 64 patients with neurological illness and 19 caregivers. Other SCI-QOL items were derived from focus groups and interviews with individuals with traumatic SCI (n=65) and clinicians who specialize in SCI (n=42).

Face Validity:

Not formally established, but content was generated from individuals with SCI and expert clinicians, so face validity is strong.

Floor/Ceiling Effects:

Excellent: minimal floor or ceiling effects. 2.8% of participants in the validation sample (Kisala et al., 2015) who completed the full item bank scored at floor; 0.1% scored at ceiling.

Responsiveness:

Not Established

Considerations:

None
