Abstract

Aim  To determine whether children with developmental disabilities show responses to pain that vary according to developmental level. Method  Factor analytical methods were used to explore whether pain behaviour is independent of developmental characteristics. As part of a longitudinal study, caregivers of 123 children (67 males, 56 females; age range 40mo-21y 6mo) completed the Non-communicating Children's Pain Checklist-Revised (NCCPC-R), the Vineland Adaptive Behavior Scales, Second Edition (VABS-II), and the Pediatric Evaluation of Disability Inventory (PEDI). Deviation intelligence quotients (DIQs) were also generated. Two varimax rotated principal components analyses (PCAs) included the NCCPC-R subscales, DIQs, and age. One also included VABS-II subdomain scores and the other, PEDI scores, to allow examination of whether pain and developmental scores produced distinct components to evaluate the independence of pain behaviour from developmental factors. Results  Children's mean age equivalents on the VABS-II were: Communication (36.4mo, SD 34.8), Daily Living Skills (31.8mo, SD 35.9), Socialization (43.2mo, SD 49.9), and Motor Skills (21.6mo, SD 20.3). Pain behaviour was distinct from developmental characteristics. The PCA including the VABS-II accounted for 78.4% of variance, with four components: Developmental Level, Pain Behaviour, Motor Development, and Chronological Age. The PCA that included the PEDI accounted for 69.4% of variance, with three corresponding components: Pain Behaviour, Developmental Level, and Chronological Age. Interpretation  Pain behaviour was distinct from developmental factors in two separate analyses using two functional measures. Clinicians can be confident that pain assessment with the NCCPC-R is not affected by children's developmental level.
