Abstract

Purpose

This study investigated the impact of work shift and fatigue on officers’ responses during simulated interactions with citizens.

Design

Using a quasi-experimental design, participants (n = 50) responded to multiple branching scenarios in a laboratory-housed use-of-force simulator. Each scenario had the potential to end peaceably or turn deadly, depending on how the officers responded. Officers who worked across four patrol shifts were tested on two occasions—after five consecutive shifts and again 72 h after completing their last shift.

Findings

Day-shift officers were less fatigued (measured using the Psychomotor Vigilance Test) than night-shift officers (f = 44.411; df = 1, 90; p < 0.001). Furthermore, officers were more fatigued when they were tested at the end of their work week than after 72 h off-duty (f = 12.030; df = 1, 90; p < 0.001). In the simulator, officers from the day shift were more likely to respond in ways that engineered cooperative outcomes (f = 4.81; df = 3, 549; p < 0.01).

Implications

These findings offer insight into how shift work and fatigue influence police–citizen interactions. Implications for de-escalation and procedural justice in policing are discussed.
