This study aims to develop a reliable and valid awareness scale that assesses levels of Endocrine Disruptor Chemicals (EDCs) engagement among allied health professionals for risk management. Preliminary item pool was created in collaboration with the expert research team and classification of the items to the sub-domains of awareness was done by the subject experts. When considering the similarities between the items, the domains were measured as general, impact, exposure, and protection awareness sub-dimensions since no model for the components were previously available. Revision of EDC items from the pool and classification to the sub-domains of awareness were completed by taking the opinions of field, measurement and language experts, other than the research team. EDC pilot test form were then applied to 380 health care workers; where inconsistent responders were excluded. Factorial structure (EFA and CFA) were simultaneously determined and reliability of EDC awareness subscales and scale measurement results were later confirmed. Finally, the EDC awareness for health care professionals with 24 items, consisting of general, impact, and exposure and protection awareness subscales, each consisting of eight items, was introduced to the scientific world. Analyses indicated that the EDC awareness scale for health professionals is statistically reliable and valid for its purpose. The EDC Awareness Scale can be used to determine the EDCs awareness levels for risk management for health care professionals.
