Children without disabilities were more involved in all activities
than were children with disabilities with the exception of working for
pay. However, as noted, differences related to disability group were
not found in some of the more structured activities (classes/lessons,
religious/spiritual activities, organization-leadership activities,
working for pay) and both groups of children tended to be least
involved in these activities. Other variables including age and
income might have partially explained the significant differences
found for organizational-leadership activities and working for pay,
but this was not examined in this study. Expectations for what is
considered acceptable involvement may account for results for
religious/spiritual activities given that there was a small effect size
attributed to the disability group (n2pZ.04) for participation
frequency here. Simply attending these activities might have been
considered acceptable involvement for some of the children with and
without disabilities.19
