Content Validity and Inter-rater Reliability of the Music Interventions in Pediatric DoC Behavior Observation Record

Aligned with best practice guidelines for patients presenting with a disorder of consciousness (DoC), music therapy interventions with this population aim to increase arousal and awareness to support emergence to consciousness. There is a significant evidence base supporting music therapy for adults with a DoC; however, there are currently no published tools that systematically capture behavioral responses of this population during rehabilitative music therapy interventions. Further, the developmentally specific response to severe brain injury in the pediatric population means pediatric-specific research is required. The Music Interventions in Pediatric DoC Behavior Observation Record (Music Behavior Record [MBR]) was developed to objectively record responses during music therapy interventions for children presenting with a DoC. To establish content validity and inter-rater reliability, a pragmatic pilot study was undertaken. Results established that the MBR has content validity with 100% agreement among participants. Overall fair-substantial inter-rater reliability in >70% of the behavioral responses recorded in the MBR indicate the MBR is an early but promising tool to objectively capture responses during music therapy interventions. The use of the MBR may ultimately support clinical advancement and intervention research to optimize consciousness recovery for the pediatric DoC population.
