Weiss Functional Impairment Rating Scale - Parent

WFIRS-P is a parent-rated functional impairment measure often used in ADHD pathways. This page is for clinics. It is not a public test and not a diagnosis.

What is the WFIRS-P?

WFIRS-P gathers a parent's view of a young person's impairment across life domains. It is an informant impairment measure, not a teacher Vanderbilt and not a self-report WFIRS-S.

Development and clinical use

The parent WFIRS was developed alongside the self-report version so clinicians could compare informant impairment with symptom ratings. It shares the WFIRS-S domain structure.

A focused informant experience

A parent or caregiver completes the form. Do not ask the young person to complete WFIRS-P as if it were WFIRS-S.

  • One question at a time with visible progress
  • Large keyboard-operable response choices
  • Previous, next, and answer-review steps
  • Clear confirmation that informant answers go to the clinic
