Spinal Cord Injury – Quality of Life Resilience

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 Resilience

Purpose:

Assess attributes of resilience in individuals with spinal cord injury.

Description:

The SCI-QOL Resilience measure is an item response theory (IRT)-calibrated item bank with 21 items that is available for administration as a computer adaptive test (CAT; range 4-12 items) or short form (SF).

Area of Assessment: Mental Health, Positive Affect, Self-Efficacy, 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 21 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 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 Resilience article (Victorson 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 mean SE of the full item bank was 0.31 (range = 0.27-0.51). The mean SE of an 8-item fixed-length CAT was 0.28 (range = 0.21-0.52). The mean SE of a variable-length CAT (min = 4, max = 12 items) was 0.27 (range = 0.21 – 0.51). (Victorson et al., 2015)

Minimal Detectable Change (MDC):

Calculated from SEM The MDC of the full item bank is 0.72. The MDC of an 8-item fixed-length CAT is 0.65. The MDC of a variable-length CAT is 0.63

Minimally Clinically Important Difference (MCID):

Not Established

Cut-Off Scores:

Not Established

Normative Data:

Traumatic spinal cord injury . The normative data are calibrated on adults with traumatic spinal cord injury so the mean score (T = 50) indicates a score that is normal for an adult with a traumatic SCI. Deviations from the mean indicate deviations from what is normal for an individual with a traumatic SCI. For example, a respondent with a score of T=60 reported more attributes of resilience than +1 standard deviation (84%) of individuals with traumatic SCI.

Test-retest Reliability:

Traumatic SCI (Victorson et al., 2015; n=717, mean age = 43.0(15.3); time post injury = 7.1 years (10.0); 45% paraplegia, 55% tetraplegia) • Excellent test-retest reliability (ICC = .79)

Interrater/Intrarater Reliability:

N/A

Internal Consistency:

Traumatic SCI (Victorson et al., 2015) • Excellent internal consistency (Chronbach's alpha = .95)

Criterion Validity (Predictive/Concurrent):

Not Established

Construct Validity (Convergent/Discriminant):

Traumatic SCI (in preparation) • The SCI-QOL Resilience item bank demonstrated good convergent validity by correlating strongly with measures of depression (PHQ-9 r = .-.57), satisfaction with life (Satisfaction with Life Scale r = .69), and positive affect (SCI-QOL Positive Affect r = .75). The SCI-QOL Resilience item bank demonstrated good discriminant validity by weakly correlating with measures of fine motor functioning (SCI-QOL Fine Motor r = .16),

Content Validity:

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. 0.14% of participants in the validation sample (Victorson et al., 2015) who completed the full item bank scored at floor; 5.6% scored at ceiling.

Responsiveness:

Not Established

Considerations:

N/A
