Figure 3. Conceptual framework for daytime sleepiness in Prader-Willi syndrome.

Figure 3

Concepts elicited from caregivers that are highlighted in green map to the items in the ESS-CHAD. The concepts highlighted in purple do not map directly onto the ESS-CHAD; these concepts, however, were closely linked to care recipients’ daytime activities but were atypical of daily routines, based on caregiver statements. ESS-CHAD = Epworth Sleepiness Scale for Children and Adolescents.
