WHAT THE TEST MEASURES

About This Assessment

Acute Physical Fatigue Assessment Questionnaire Test - Symptoms and Signs

fatigue

This questionnaire is a brief self-report measure intended to assess acute, workday-related physical fatigue. The Acute Physical Fatigue Assessment Questionnaire is designed to capture the intensity of fatigue symptoms that may develop over the course of a single day across a range of activity demands.

The measure consists of 18 items and typically takes about 4 minutes to complete. Respondents rate fatigue-related experiences to support rapid screening and monitoring; results may inform decisions about workload, scheduling, and rest planning in occupational or educational settings. The Acute Physical Fatigue Assessment Questionnaire is attributed to David M. Borg.
