Prior research has shown that some patients respond better than others to adjunct therapy than others. Caregivers may be reluctant to initiate such therapies unless they are certain it will be beneficial. Kwekkeboom has developed and tested the Imaging Ability Questionnaire (IAQ) and the Kids Imaging Ability Questionnaire (KIAQ) to help determine who would benefit from this type of intervention (Kwekkeboom, Maddox, West, 2000). Participants will be completing these questionnaires prior to the first VR therapy session. The instruments for both groups will be the same with the exception of the "imaging ability". Each group will complete an "imaging ability", but one has been designed especially for children, the other for adults.
