Subjective and Objective Fatigue Metrics Improve Construction Safety

Assessing worker fatigue through both self-reported scales and objective physiological/performance measures is crucial for enhancing safety in the demanding construction industry.

PLoS ONE · 2024

01

Key Findings

  • 01Subjective self-response questionnaires, categorized as single or multidimensional, can assess both physical and mental fitness.
  • 02Objective measurement tools include physiological metrics and physical/cognitive performance measures.
02

Application

Design takeaway

Integrate diverse fatigue assessment methods into safety management systems for construction projects.

How to apply

When designing safety protocols or wearable technology for construction workers, include features that allow for both self-reporting of fatigue and objective data collection (e.g., heart rate, reaction time).

Project actions

  • 01When researching user fatigue, consider both qualitative (surveys, interviews) and quantitative (biometric data, performance tests) approaches.
  • 02Focus on the practical application of your findings within a specific industry context.

Method & Evidence

AimWhat are the most effective subjective and objective measures for evaluating work-related fatigue in construction workers to improve safety performance?
MethodSystematic Review
ProcedureA systematic review was conducted by searching three databases using 37 keywords from inception to 2022, adhering to the PRISMA protocol. 20 relevant articles published between 2008 and 2022 were selected and appraised using the Mixed Method Appraisal Tool (MMAT).
ContextConstruction Industry Safety

Variables

IVMethods of fatigue assessment (subjective vs. objective)
DVSafety performance, fitness for duty
CVConstruction industry context, type of construction task
04

Strengths & Limitations

Strengths

  • +Comprehensive search strategy adhering to PRISMA guidelines.
  • +Use of a recognized appraisal tool (MMAT).

Limitations

On-site data collection can be challenging due to environmental factors and worker availability.

Reliability & validity

The reliability of subjective measures can be affected by individual interpretation, while the validity of objective measures depends on their direct correlation with actual safety outcomes.

Think critically

How might the effectiveness of subjective fatigue measures be influenced by social desirability bias among construction workers?

05

Design Principles

"Comprehensive assessment of human factors, including both subjective experience and objective performance, is essential for optimizing safety in high-risk environments."

The construction industry's inherent risks necessitate a proactive approach to worker well-being. Understanding and mitigating fatigue can directly reduce accidents and improve overall operational safety.

06

What This Means for Your Design

To keep construction workers safe, we need to check if they are too tired to work. This can be done by asking them how they feel and also by measuring things like their heart rate or how fast they react.

How to use in your project

  • 1.Use this research to justify the inclusion of fatigue assessment methods in your design process, particularly if your project involves demanding physical or cognitive tasks.
