Developmental domains, such as cognitive, language, and motor, are key concepts of interest in longitudinal studies of intellectual and developmental disabilities (IDD). Normative scores (e.g., IQ) are often used to operationalize performance on standardized tests of these concepts, but it is the interval-distributed person-ability scores that are…

Woodman, A. C.; Hauser-Cram, P. – Journal of Intellectual Disability Research, 2013
Background: Parents of children with developmental disabilities (DD) face greater caregiving demands than parents of children without DD. There is considerable variability in parents' adjustment to raising a child with DD, however. In line with a strengths-based approach, this study explores coping strategies as potential mechanisms of resilience…
