Insights
New short forms (SFs) for the Pediatric Measure of Participation (PMoP) are validated for assessing child and parent outcomes after spinal cord injury (SCI) when computerized adaptive tests are not feasible.
Area of Science:
- Pediatric rehabilitation
- Outcomes assessment
- Spinal cord injury (SCI) research
Background:
- Assessing participation is crucial for children with spinal cord injury (SCI).
- Existing measures may not be suitable for all clinical situations.
- Development of shorter, validated instruments is needed.
Purpose of the Study:
- To develop and validate short forms (SFs) of participation for child- and parent-reported outcomes in pediatric SCI.
- To create tools that are practical for use in various clinical settings.
Main Methods:
- Multi-center cross-sectional cohort study involving three pediatric orthopedic hospitals.
- Expert panel utilized calibration data from a pediatric computerized adaptive test (CAT) development study.
- Selected items for two domains: self-relevant participation and friends-relevant participation, with child and parent versions.
- Conducted psychometric analyses including reliability, agreement, floor/ceiling effects, and test information function.
Main Results:
- Developed and validated short forms (SFs) for the Pediatric Measure of Participation (PMoP).
- Demonstrated acceptable group reliability (0.74-0.92) and strong agreement (0.89-0.95) between SFs and item banks.
- Reported minimal floor effects and acceptable ceiling effects across SCI severity levels (paraplegia/tetraplegia).
Conclusions:
- The Pediatric Measure of Participation (PMoP) SFs are psychometrically sound.
- These SFs are suitable for assessing participation outcomes in pediatric SCI when CATs are not feasible.
Study Design:
Multi-center cross-sectional cohort study.
Objectives:
The objectives of this study were to develop and validate short forms (SFs) of participation for child- and parent-reported outcomes following spinal cord injury (SCI).
Setting:
Three pediatric orthopedic hospitals in the United States.
Methods:
The expert panel used calibration data from the pediatric computerized adaptive test (CAT) development study (convenience sample of 381 children and adolescents with SCI and 322 parents or caregivers) to select SF items. The panel selected items for two domains (participation self-relevant to what I want to do; participation friends-relevant to what my friends do), with parent and child versions for each domain. Psychometric analyses included group reliability, Cronbach's alpha, agreement (SFs and item banks), percent of sample with highest (ceiling) and lowest (floor) scores by level of lesion (paraplegia/tetraplegia), and test information function.
Results:
Group reliability and Cronbach's alpha values are acceptable (0.74-0.92) and agreement (intraclass correlation coefficients for SFs and total item banks) is strong (0.89-0.95). Floor effects were minimal for people with tetraplegia and paraplegia (0-1.19%). Ceiling effects were minimal for people with tetraplegia (0-3.13%) and slightly higher, but acceptable, for people with paraplegia (8.06-14.02%). Test information function for the SFs was sufficiently high over the range of scores for the majority of the sample.
Conclusion:
Pediatric Measure of Participation (PMoP) SFs are acceptable for use when CATs are not feasible.
