Pandemic Fatigue Scale

The Pandemic Fatigue Scale (PFS) measures psychological exhaustion and reduced motivation to maintain protective behaviors during prolonged pandemics. Developed by Restrepo and colleagues, it captures the phenomenon whereby individuals progressively abandon preventive measures (distancing, mask-wearing, testing) despite ongoing transmission risk, driven by 'fatigue' or loss of motivation rather than reduced threat perception. The PFS has become essential for monitoring behavioral adherence trends and explaining divergence between risk and protective behavior during multi-wave pandemics.
