Abstract

Primary objective: The Acquired Brain Injury Challenge Assessment (ABI-CA) was created to fill a measurement gap and evaluate deficits in advanced motor skills in children with acquired brain injury (ABI). Study objectives were to refine ABI-CA response options and evaluate (i) inter-/intra-rater reliability, (ii) concurrent validity and difficulty level in relation to the Community Balance & Mobility Scale (CB&M) and (iii) administration efficiency of the refined ABI-CA. Research design: Measurement study.

METHODS: Phase I involved ABI-CA revisions. Phase 2 consisted of live-/video-scoring of the ABI-CA with 15 typically-developing (TD) children and 15 with ABI (7-17 years) to assess reliability/validity.

RESULTS: The revised 20-item ABI-CA displayed excellent reliability for the entire sample (ICCs > 0.90; 95% CI = 0.92-1.00; SEM ≤ 3.60) and within ABI and TD sub-groups. The ABI-CA and CB&M correlated strongly (r = 0.75, p < 0.0001). The ABI-CA mean score (/100) was 11.3 points lower (p < 0.0001) than the CB&M's mean score (/100).

CONCLUSION: The ABI-CA demonstrated excellent reliability and initial evidence of validity. ABI-CA scores were lower overall than the CB&M, indicating the ABI-CA may have greater capacity to evaluate improvements in advanced motor skills in children with ABI. Multi-centre research is needed to confirm the ABI-CA's test-retest reliability and, assuming acceptability, assess responsiveness to change.
