ANCOVAs (adjusting for age and income category) and partial eta squares were also used to compare mean item-level scores for participation frequency and involvement between children with and without disabilities.
Chi-square analyses were used to compare the percentage of parents in each group who responded (a) “never” for participation frequency items; (b) “yes” for desired change items; (c) “usually makes harder,” “usually helps,” and “not an issue” to environmental support and barrier items; and (d) “usually, no,” “usually, yes,” and “not needed” to availability/adequacy of resources items. Because of multiple comparisons,Bonferroni corrections were made to significance levels by
dividing .05 by the number of comparison tests conducted for each set of analyses.
