validity. (Ryan et al. 2006, pp. 195-200). The internal consistency of each domain ranges
from 0.64 to 0.92 with an overall Cronbach's alpha of 0.94 (Ryan et al. 2007). The ICCs for
each domain range from 0.77 to 0.92 and the overall ICC is 0.92 [95% confidence interval
(CI) 0.86-0.95] (Ryan et al. 2007). Examples of three supervision questions include “I have
little time to get chores done around the house,” “I'd like my child to be as independent
as possible,” and “It is easier to play with my child when someone is holding him/her.”
An example of a family/social interaction question is as follows, “My child socializes
with others at mealtime.”

Step 1.
In concert with the clinician, Charlie and his family decide they would like to
improve Charlie's independent mobility.
Table 5.3 provides baseline assessment data using the Family Impact of Assistive
Technology Scale regarding their current strategy. For the sake of brevity, description of
specific assessments of his physical and cognitive, perceptual status, and postural control
are omitted here. As can be noted at baseline in Table 5.3 and Figure 5.3, Susan and Harold
are quite concerned about Charlie's autonomy and his performance of activities and about
their effort (involved in carrying him places) and limited caregiver relief. Family/social
interactions and supervision are less of a concern.
Step 2.
Their current strategy of moving Charlie is becoming untenable for Susan and
Harold because as Charlie grows, his parents are finding it increasingly difficult to carry
him for long distances. Although Charlie can still walk, if he walks far he becomes very
fatigued, so this option is no longer realistic. The parents have resisted using AT because of
the stigma associated with its use, perceived accessibility issues, and some denial about his
diagnosis, but at this point they feel that the benefits would outweigh the disadvantages.
Step 3.
There are a variety of options to choose from, including use of a walker, a manual
wheelchair, or power mobility. Given the progressive nature of Charlie's condition and
