Nursing care involves a continuous interaction between nurses and people with disabilities. This has created a need for assessment tools that measure nurses' knowledge about the basic human needs of people with disabilities. The aim of this cross-sectional study was to develop a Knowledge of Basic Human Needs Scale and investigate nurses' levels of knowledge about the basic human needs of people with disabilities and their association with nurses' education. Data were analyzed using principal component analysis to test the construct validity and to identify factors using principal varimax rotation. The reliability estimate was based on Cronbach's alpha coefficient. Linear regression models were used to assess the association between knowledge about basic human needs and predictors. Factor analysis extracted eight factors, explaining 66.3% of the total variance. The sampling adequacy, criterion validity, and internal consistency were satisfactory. The nurses' levels of education was associated with their knowledge about the basic human needs of people with disabilities. The questionnaire constitutes a valuable contribution to improving nurses' knowledge and practice, as well as the quality of healthcare, and it provides a contribution to improving the quality of life for people with disabilities.
