Abstract Background/aim: Although traffic accidents are an important public health problem, reducing mortality and morbidity is directly related to the knowledge, attitudes and behaviors of healthcare professionals. Investigating the causes of injury and death in vehicle accidents has gained importance with the development of electric vehicle technology in recent years. These issues are directly or indirectly under the responsibility of forensic medicine. The aim of this study is to develop an Electric Vehicle Accidents Attitude Scale (EVAAS) regarding cognitive, affective and behavioral dimensions to determine the attitudes of healthcare professionals towards electric vehicle accidents. Materials and methods: The sample group of the study consisted of 386 physicians, paramedics, emergency medicine technicians and ambulance drivers working in the emergency services and 112 units of public state and university hospitals in Türkiye. The Delphi technique including expert opinions was utilized in the development of EVAAS and validity and reliability analyses were carried out after a focus group study and pilot application process were completed. Results: The 27-item EVAAS was grouped under 3 dimensions-factor- (cognitive, affective, and behavioral) explaining 65.257% of the total variance. Cronbach's Alpha coefficient for EVAAS was 0.859, retest reliability was 0.781, and the test-retest reliability was calculated as 0.766 (Table 2). Conclusion: A valid and reliable EVAAS consisting of 27 items in three dimensions: cognitive, affective and behavioral was developed in the study.
