Official Title: Validation of the ItchRO Diaries in Pediatric Cholestatic Liver Disease

Brief Summary: The purpose of the study is to validate the ItchRO instrument (a clinical outcome assessment measure of itching) prior to the analysis of longitudinal treatment effect data being generated in ongoing clinical trials.

Detailed Summary:

This research will examine the psychometric performance of the electronic diaries for the itch-reported outcome (ItchRO) measure for both patients and caregivers in a stand-alone 2-week validation study in the target patient population. The study is non-interventional in nature; the purpose of the study is to validate the ItchRO prior to the analysis of longitudinal treatment effect data being generated in ongoing clinical trials. Following training and initial completion of the electronic diaries, families will return home and complete the diaries twice daily over the course of two weeks. Additional assessments include the numerical rating scale to assess itching, the patient impression of change (PIC), the caregiver impression of change (CIC), PedsQL (pediatric quality of life), children's sleep habits questionnaire (CSHQ), and clinical scratch scale.

Longitudinal data will be used to follow the natural (non-interventional) course of the disease and the quality of the data. Test-retest reliability will be assessed using diary data from Day 1 to Day 14 in stable subjects as measured by the PIC for the child-completed measure and the CIC for the caregiver measure. Convergent validity (correlations between the ItchRO and similar concepts on the other measures included in the study) will also be explored (such as the correlation between sleep and morning ItchRO diary scores). Clinical validity (correlation between the ItchRO and clinician reports) and preliminary responsiveness of those who changed in their itching status over the two week period will also be assessed if sample sizes allow.

Current Primary Outcome: Validation of ItchRO measure [ Time Frame: 2 weeks ]

Validate the ItchRO measure with subjects with Alagille Syndrome (ALGS) or Progressive Familial Intrahepatic Cholestasis (PFIC) and/or their caregivers through the completion of the electronic diary twice daily over the course of two weeks.
