The current research aims to identify the psychometric properties of the Psychological Immunity Scale among a sample of first year secondary school and Al-Azhar students. To achieve this goal, a random sample of (206) male and female students was selected, divided into (92) male and (114) female students from the first year of general secondary school and Al-Azhar in the Sharkia Governorate in the educational administrations of (Deirb Najm and West Zagazig) for the first semester of the year. Academic year (2023-2024 AD), where the psychological immunity scale was applied, consisting of (37) situations, distributed over six dimensions. Using the “SPSS” program to reveal the psychometric results, the factorial validity and attitudinal validity of the scale were calculated, and the significances of the scale’s reliability indicators were calculated using the “Cronbach’s Alpha” method and the class reliability of the scale as a whole. The indications of the internal consistency indicators of the scale were also calculated by calculating the correlation coefficients between the scores of each attitude. From the positions of the scale and the overall degree of the dimension to which it belongs, as well as between the dimensions and the scale as a whole and their level of significance. The results showed that the psychometric properties (validity and reliability) of the psychological immunity scale were available among a sample of general and Al-Azhar secondary education students to a degree
