(1) Abbreviations: SaCl = Safety climate; SaMo = Safety motivation; SaKn = Safety knowledge; TFL = Transformational leadership; SLMX = Safety-specific leader–member exchange; SaCo = Safety compliance; SaPa = Safety participation; (2) The constructs of transformational leadership and safety-specific leader–member exchange were measured with a six-point Likert scale; the constructs of safety climate, safety motivation, safety knowledge, safety compliance, and safety participation were measured with a seven-point Likert scale; (3) Correlations are below the diagonal. The italics on the diagonal are average variances extracted of the corresponding constructs; (4) ** p < 0.01; * p < 0.05.
