The goal of this study was to develope Serenity Scale suitable for Turkish culture. The scale's construct validity was investigated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The association between the Serenity Scale, Peace Scale, and Authentic Happiness Scale was examined in order to assess the criterion-related validity. The Cronbach alpha internal consistency coefficient was determined and the equivalent halves approach was employed for the reliability analysis. In addition, the item discrimination coefficient was calculated by calculating the difference between the upper and lower 27% score averages. The research data were collected online from two distinct groups of people aged 18-35. A three-factor structure with 21 items was obtained with 306 participants in the EFA stage and 365 participants in the CFA stage, for a total of 671 participants, according to the results of the EFA and CFA performed within the context of the research. The Cronbach alpha internal consistency coefficients calculated for the wholesale scale in the three-factor final structure were calculated as .90. The correlation value between the scores of the two halves of the form, which was divided into odd and even numbers in the equivalent halves method was examine a strong positive correlation was found between the two halves of the method of comparing the upper 27% and lower groups of 27%, which was applied to test the reliability of the measurement tool, it was revealed that the difference between the mean scores of the upper and lower 27% groups was significant. As a result, it can be stated that the Serenity Scale is a reliable and valid measurement tool.
