Research indicates that resilience is the concept that best explains individuals' efforts to heal the effects of negative experiences and recovery processes after difficulties. Hence, it is considered substantial to study the construct of resilience and the psychometric properties of the scales that measure this structure. The objective of this study is to evaluate the psychometric properties of the Brief Resilience Scale within the scope of the Rasch Partial Credit model. In this direction, the aim was to contribute to the literature with a research study that may be an example of the use of the Partial Credit Model in the assessment of the scales. The study group of the research consists of 608 individuals. As a data collection tool, The Brief Resilience Scale, which is widely used in social sciences and consists of six items and one dimension, was used. The analysis of the obtained data was performed based on the Rasch Partial Credit Model. After the unidimensionality and local independence assumptions of the Rasch model were tested, it was determined that all the items were compatible with the model. At the same time, it was seen that the five-point scale utilized in the scale worked effectively, and that the observed and expected values in the item characteristic curves overlapped. Based on the outcomes of the Likelihood Ratio, according to gender, the sixth item showed non-uniform, and the fifth item showed uniform negligible Differential Item Functioning. In line with all these findings, it has been demonstrated that the Brief Resilience Scale provides valid and reliable results within the scope of Rasch PCM.
