This study aimed to systematically review studies of the psychometric properties of the self-rated successful aging inventory (SAI). The literature was rigorously searched from July 2018 to February 2021 and relevant studies were selected and evaluated following the Consensus-based Standards for the selection of health Measurement Instruments guidelines. A total of 23 studies were included, in which 19 instruments were identified. Due to the quality of the studies, only preliminary conclusions could be drawn. Seven instruments were graded "A" and recommended for use based on the available psychometric evidence. The remaining 12 SAI instruments were graded "B" and more research is required before they can be recommended. Based on this review, seven different types of the SAI could be considered for use. To improve the quality of evidence, the SAI requires more rigorous research and precise reports. When using the SAI, it is important to consider cultural characteristics.
