This study aims to develop a scale to measure eight-grade secondary school students' attitudes towards individual peace. The items of the scale have been prepared by the researcher based on a literature review. The study sample included 223 eight grade students from different schools in the Mamak district of Ankara for the 2015-2016 school year. At the end of the analysis, the correlation coefficients obtained from item-factor total and adjusted correlation were found to be above .21 and all items were statistically significant. In the exploratory factor analysis (EFA), the scale items were split into four dimensions: "State before Peace", "Factors for Peace", "Factors for Sulking" and "Assitance in Peacemaking". The Chi-square (X2) value appropriate for the model developed based on the results of the Confirmatory Factor Analysis (CFA) and statistical significance levels showed that the proposed model was appropriate for the collected data. Reliability coefficients tested for the whole scale and its sub-dimensions revealed that the scale was suitable to measure eight-grade secondary school students' attitudes towards peace.
