Özet:

It is important that the researchers are supported by field research in order to determine the validity of the assumptions they present in their studies. Research requires appropriate tests and measurements to be able to obtain objective results and to collect data. In scientific research, one of the data collection sources used in the point of being able to reveal new data or to correctly identify problems and produce solutions is scale. Developing scale is a very challenging and challenging task. The difficulties arise from the aim of developing a scale with the best possible validity and reliability. It is necessary to create a good structure validity for a good validity. The validity of the structure is the degree of the structure desired to be measured by the test. Applications of Opening Factor Analysis are used to ensure the validity of the structure. Opening Factor Analysis is a type of analysis that tries to explain with fewer variables by combining the variables that measure the same structure. This aggregation work was done to reveal how Opening Factor Analysis is applied in scale development studies, with its stages and examples; to explain its characteristics, purposes, assumptions and concepts.
