This study examined the psychometric properties of test presentation and response formats that were modified to be accessible with the use of assistive technology (AT). First, the stability of psychometric properties was examined in 60 children, ages 6 to 12, with no significant physical or communicative impairments. Population-specific differences were then examined with samples that included 24 children with cerebral palsy and matched control peers. Children were administered standard and modified versions of tests. The type of AT access did not have a statistically significant effect on modified test scores. Measurement stability between the standard and modified versions of quadrant forced-choice format tests was sufficient. The findings support the potential use of AT and accessible procedures for some test instruments in the assessment of children with cerebral palsy.

Predictors of reading comprehension were evaluated in 41 children with cerebral palsy and 74 typically developing children between the ages of 6 and 12 years. Regression analyses were conducted to determine the relative contributions of measures of phonemic awareness, receptive vocabulary, and general reasoning to variance in reading comprehension. All three independent variables were statistically significant predictors of reading comprehension in both groups of participants. The impact of phonemic awareness on reading comprehension was moderated by age, but only in the typically developing group. Within the group with cerebral palsy, there was an indirect effect of functional expressive ability on reading comprehension, mediated by phonemic awareness. It is concluded that largely the same variables predict reading comprehension in children with cerebral palsy as in typically developing children, but that children with cerebral palsy continue to rely on phonological processing for a more protracted period of time.
