Background and Purpose: Information security is the use of a set of policies, solutions, tools, hardware, and software to provide a threat-free environment in the generation, refinement, transmission, and distribution of information. The purpose of this study was to assess the validity and reliability of the Human Factors Inventory affecting libraries' information security.
Materials and methods: The present study was a cross-sectional study conducted for designing and psychometric evaluation for the inventory. After designing the initial list of inventory items, the opinion of expert lecturers and senior managers of Iranian libraries was used to evaluate face and content validity using Lawshe, content validity ratio (CVR) and Content validity index (CVI). Cronbach's alpha coefficient was used to assess the overall reliability of the questionnaire. Data were analyzed using SPSS software.
Results: The results showed that each of the items in the inventory had face validity and content validity (CVR> 0.75). Besides, the content validity index was set to 0.87 in all dimensions of the inventory, which is an acceptable number for the inventory. Cronbach's alpha coefficient was calculated as 0.946 and the reliability of the instrument was confirmed.
Originality/Value: In this study, for the first time, an inventory was designed and psychometrically assessed for human factors affecting library information security. Library and information science professionals and librarians can use this tool in research activities.
