Instrument Attributes
- The FA-HI is a patient-reported outcome (PRO) measure designed to assess symptoms and health-related quality-of-life from the perspective of patients with Friedreich’s ataxia.
- Designed and validated to fully satisfy published FDA guidance for use in drug-labeling claims and measure how a patient feels and functions.
- The FA-HI is a fully valid, reliable, responsive, and disease-specific instrument capable of measuring changes in patient-reported health in patients with Friedreich’s ataxia in response to therapeutic intervention during clinical trials or clinical monitoring.
- The FA-HI was developed using extensive patient input, including an analysis of 1,152 adult and 571 minor patient quotes and a large cross-sectional study involving 153 patients.
- The FA-HI is highly relevant to patients, has low patient burden, correlates with markers of disease severity, and demonstrates no floor or ceiling effects.
- Utilized by academic and industry groups in multiple longitudinal trials.
- The FACR-HI is a caregiver-reported outcome (CRO/ObsRO) measures designed to assess the disease burden of a patient from the perspective of the caregiver.
- The FACR-HI was developed using extensive caregiver and patient input, including an analysis of 805 caregiver quotes and a large cross-sectional study involving 49 caregivers.
- The FACR-HI is highly relevant to patients using the perspective of the caregiver, has low patient burden, correlates with markers of disease severity, and demonstrates no floor or ceiling effects.

Instrument Scoring
All subscales are scored on a scale of 0 to 100 with 0 representing no disease burden and 100 representing the maximum level of disease burden. Symptom questions within each subscale are weighted based on participant-reported prevalence and average impact as identified through the cross-sectional study. Subscale scores are also weighted to generate a total FA-HI or FACR-HI score (0-100) representing overall disease burden.
