Data Sheet 1_The job demands–resources model and safety behavior in construction work: a systematic review and meta-analysis of six dual-process paths.zip

Background<p>Construction workers’ safety behavior is central to accident prevention, yet the psychological paths linking work characteristics to safety behavior have not been transparently synthesized in the construction industry.</p>Methods<p>This systematic review and meta-analysis examined the six-path Job Demands–Resources (JD-R) model and evaluated extreme heat as a possible contextual boundary condition. Following a revision-stage construct and dependency audit, we synthesized 194 zero-order correlations from 63 reports representing 64 independent samples (N = 22,846) with random-effects models.</p>Results<p>Job demands were positively associated with strain (r = 0.321), job resources with motivation (r = 0.578), and motivation with safety behavior (r = 0.439).

The pooled strain–safety behavior association was small and inconclusive (r = −0.060; I² = 99.0%). The two cross-links were based on few samples and are therefore descriptive only: demands–motivation r = −0.124 (k = 5) and resources-strain r = −0.294 (k = 3). No evidence of heat-proxy subgroup differences was found for resources–motivation (p = 0.628) or motivation–safety behavior (p = 0.463), while demands–strain and strain–safety behavior could not be tested because no eligible high-heat samples remained.</p>Conclusion<p>These results indicate insufficient evidence to establish heat moderation, rather than evidence that heat is irrelevant.
