Modelling antecedents of safety compliance: Incorporating theory from the technological acceptance model

•Compliance is influenced by motivation and the perceived usefulness of procedures.•Organizational safety support influences compliance via perceived usefulness.•Supervisor safety support influences compliance via safety motivation.

Research into the technology acceptance model (TAM) and safety performance was used to develop a model in which perceived organizational and supervisor support for safety affect employees’ compliance with a risk-awareness safety procedure via cognitive–motivational mechanisms. Cross-sectional survey data were collected from 374 employees of a large Australian mining company. Results of path analysis show that both perceived organizational safety support and perceived supervisor safety support influenced compliance with the risk-awareness procedure, although through different cognitive–motivational processes. Perceived organizational safety support was significantly associated with compliance via perceived usefulness of the risk-awareness procedure. On the other hand, perceived supervisor safety support was significantly related to compliance via safety motivation. The implications for theory and practice are discussed.
