Purpose/Significance To review assessment tools for adult health information overload, and to provide references for tool selection.Method/Process Databases such as CNKI, Wanfang Data, VIP Database, PubMed and Embase are retrieved. Basic information of literatures and assessment tools are extracted and analyzed.Result/Conclusion A total of 19 literatures are included, covering 22 assessment tools for adult health information overload. These tools have good reliability, but the validity verification and development verification methodologies of some tools need to be improved. In the future, their core categories and attributes should be further determined through methods such as concept analysis, and an assessment framework of “generic core scale+specific module” should be developed. Combined with objective measurement techniques, the accuracy and clinical applicability of the assessment should be improved.
