However, due to potential hazards such as chemical, biological, and physical agents, laboratories are inherently considered dangerous work environments. Therefore, it is essential to have a reliable and valid tool to evaluate the safety of these environments comprehensively. Therefore, this study was conducted to design and psychometrical evaluation a comprehensive tool for safety evaluation in university laboratory complexes. </span></span></span></span></span></span><br>
<span style="font-size:12pt"><span style="line-height:normal"><span style="unicode-bidi:embed"><span new="" roman="" style="font-family:" times=""><span style="font-size:11.0pt"><span style="color:#0e101a"> <b><i>Materials and Methods:</i></b> In the first stage, a Checklist was developed across various areas through a process that involved using a literature review, field visits, Interviews with laboratory technicians, and creating videos from multiple laboratories. The initially designed questionnaire was sent to 10 safety experts for face validity, and then their comments on the question phrasing were considered. To assess the content validity, two measures were employed: the Content Validity Ratio (CVR) and the Content Validity Index (CVI). Additionally, the reliability of the instrument was evaluated using Cronbach's alpha calculation method.</span></span></span></span></span></span><br>
<span style="font-size:12pt"><span style="line-height:normal"><span style="unicode-bidi:embed"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:11.0pt"><span style="color:#0e101a">Results:</span></span></i></b><span style="font-size:11.0pt"><span style="color:#0e101a"> In the initial stage, a total of 286 questions were designed within 9 different areas. Subsequently, 49 questions were removed by expert members due to overlapping concepts, resulting in a final questionnaire consisting of 237 questions. The content validity index and relative coefficient were found to be above 0.8 in all areas, indicating strong content validity. Furthermore, Cronbach's alpha value exceeded 0.7 in all areas, suggesting a desirable level of reliability for the designed program.</span></span></span></span></span></span><br>
<span style="font-size:12pt"><span style="line-height:normal"><span style="unicode-bidi:embed"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:11.0pt"><span style="color:#0e101a">Conclusion:</span></span></i></b><span style="font-size:11.0pt"><span style="color:#0e101a"> The results of this study demonstrate that the developed questionnaire exhibits acceptable levels of validity and reliability. As such, it can serve as a comprehensive and suitable tool for monitoring safety in University complex laboratories.</span></span></span></span></span></span><br>
