This research aims to create a tool that will allow researchers to assess the maternal identity of women who cared for young children during the COVID-19 pandemic. The methodological goal of this study is to create a maternal identification tool for women raising young children and to confirm the tool's reliability and validity. It is divided into two stages: tool development and tool evaluation. The data collection period lasted from July 1, 2021, to July 30, 2021, and it was carried out after gaining prior consent from institutions such as public health centers through an official letter. Four factors and 22 items were chosen from the factor analysis. Finally, through reliability and validity testing, 17 items were constructed into four sub-factors: "warmth type," "best effort type," "indifference type," and "preparation type." An essential point in the tool development process is to verify the validity and reliability of the tool appropriately, theoretically, and methodically. Because of this, a test was created specifically for this study to evaluate the maternal identity of domestic women raising young children. The instrument's validity and reliability was verified.
