| description | Background and Objective: The growing use of chemicals in academic laboratories has underscored the need for a tool to measure the awareness of students about labeling, hazards, and characteristics of chemicals. Regarding this, the present study was conducted to design and validate a questionnaire facilitating the assessment of student’s knowledge about chemical hazards.
Materials and Methods: The current research was conducted in two stages, involving the design and evaluation of the validity and reliability of the questionnaire, in 2019. The validity of the designed questionnaire was evaluated based on the opinions of 10 subject-matter experts using content validity ratio and content validity index (CVI). In addition, Cronbach's alpha coefficient was calculated to determine the reliability of the questionnaire.
Results: The mean (SD) age of participants was 20.61 (0.998) years and 58.33% of the them were female and 41.67% were male. The CVI and Cronbach's alpha coefficient of the questionnaire were estimated at 0.938 and 0.728, respectively, which are acceptable values.
Conclusion: The results showed that the reliability and validity of the designed questionnaire were acceptable and that this tool can be used to measure people awareness regarding the safe use of chemicals. |
