Development of Child and Family-Centered Engagement Guidelines for Clinical Administration of the <i>Challenge</i> to Measure Advanced Gross Motor Skills: A Qualitative Study

<i>Aims</i>: This article describes a qualitative study aimed at producing child-centered guidelines for the administration of a measure of children's advanced gross motor skills, the <i>Challenge</i>. The purpose of the guidelines is to promote collaborative interpretation and application of results. <i>Methods</i>: The study was conducted in three Canadian cities and included 31 children with cerebral palsy (GMFCS Level I or II) ages 8 to 18 and one parent/caregiver per child (<i>N</i> = 62 participants). Following <i>Challenge</i> administration, each child and one of their caregivers took part in separate qualitative interviews. Analyses were oriented to exploring understandings of the purposes of testing, impressions of the child's performance, and perceptions of how results might inform activity choices and interventions. <i>Results</i>: Three themes were generated: investments in doing well; I know my child/myself; and caregivers' interpretations of child's performance. Themes were then integrated with principles of child and family-centered care to develop The <i>Challenge</i> Engagement Guidelines directed at reducing test anxiety and enhancing shared decision making. <i>Conclusions</i>: The Guidelines are the first of their kind to integrate child and family-centered principles into the administration protocol of a motor measure. Although developed for the <i>Challenge</i>, the principles have applicability to other rehabilitation measures.
