Reliability and validity of a measure of service providers' perceptions of child and parent engagement in pediatric rehabilitation therapy sessions.

BACKGROUND

There is growing interest in client engagement in pediatric rehabilitation. This article investigated the psychometric properties of a measure of service providers' perceptions of the affective, cognitive and behavioural engagement of both children with disabilities and their parents in pediatric rehabilitation therapy sessions.

METHODS

Test-retest reliability of the Pediatric Rehabilitation Intervention Measure of Engagement-Service Provider version (PRIME-SP) was examined using engagement ratings made by 60 service providers for 77 children and 73 parents. Construct validity was examined using the known-group validity technique, utilizing service providers' ratings of the engagement of parents and their children attending the same session with the service provider. We hypothesized that there would be significantly different, yet moderately correlated engagement ratings for children and their parents.

RESULTS

There was evidence of moderate test-retest reliability for the child ratings, indicative of dynamicity across occasions, but also a degree of consistency, as aligned with our expectations. Service providers' ratings of parent and child engagement were not significantly correlated and paired t-tests indicated significantly higher engagement scores for parents than children.

CONCLUSIONS

The study provides preliminary evidence to support the reliability and validity of the PRIME-SP as a tool for service providers to document, reflect on and monitor child and/or parent engagement.
