Mixed methods cohort study.
To develop and assess psychometric properties of the pediatric measure of participation (PMoP) short forms (SF) version 2.0.
Secondary analyses of data collected from 381 children with spinal cord injury (SCI) of at least 3-month duration living in the community, and 322 parents of children with SCI at three pediatric orthopedic hospitals in the United States.
Mixed methods iterative process to customize SF based on, highly relevant items, age and school analysis of item distributions; ceiling and floor effects; internal consistency and group-level reliability; correlation of SF scores with scores derived from the total item bank; and assessment of the degree to which item difficulty matched the abilities of children in the sample.
PMoP SF V2.0 mean T scores ranged from 47.59 to 51.23. Overall, mean scores were somewhat higher for older children and parent respondents. Group-level reliability values ranged from 0.66 to 0.79; Cronbach’s alpha values ranged from 0.79 to 0.90; ICC values ranged from 0.89 to 0.95. Pearson Correlations ranged from 0.80 to 0.95, showing good to strong correlation between scores from the SFs and total item bank for each domain. Test information function demonstrated that score estimates will be less precise at higher ends of the scale.
PMoP SFs V2.0 contain items relevant to participation among children with SCI, and are tailored for four age groups and school status. They are recommended for use when computer adaptive testing (CAT) is not possible.
