The goal of the current research is to identify the positive mood among middle school students, and to achieve the research objectives, the two researchers built a positive mood scale according to the theory and definition (Fredrickson,1998). The face validity and construct validity were verified, and the reliability was verified by the retest method, as the reliability rate reached ( 0.92) while the reliability coefficient using the Cronbach’s alpha method reached (0.75). After that, the scale was applied to the basic research sample consisting of (400) male and female students from Baqubah Center schools. The research sample was chosen by a random stratified method with proportional distribution and treatment. Statistically, the researchers used the statistical package (SPSS) for the study data, and the results showed that the sample members had a high positive mood compared to the theoretical average of the scale. In light of the results, the current research came out with a number of recommendations and proposals.
