This study was intended to recognize the relation between self-harm and shocking childhood experiences and its dimensions (physical negligence, physical abuse, emotional negligence, emotional abuse, sexual abuse and lying) with the secondary school girls, as well as recognizing the differences in self-harm and shocking childhood experiences as per age, accommodation and siblings birth order. The research sample included (312) secondary school female students. Using statistical analyzes of the variables, the results shown: 1. The statistically referring correlation is positive in the significance level of (0.01) in Coefficient of correlation(0.404), in respect of the dimensions of physical abuse, emotional abuse and sexual abuse. While the correlation is referring and negative in the significance level of (0.01) in the Coefficient of correlation(-0.326) in respect of the dimensions of physical negligence and emotional negligence. 2. The existence of statistically significant differences in the significance level of (0.01) in average(2.08), which matter may have resulted from the variable of age. 3. Non existence of statistically significant differences in the significance level of (0.05) between average grades of female students on the shocking childhood experiences scale and its dimensions, which matter may have resulted from the variable of age. 4. The existence of statistically significant differences in the significance level of (0.05) in average(6.60), between average answers of female students living with their parents and those of female students living with their father. 5. The existence of statistically significant differences in the significance level of (0.05) in average(0.516), between average answers of female students living with their parents and those of female students living with their father in favor of those living with their father. 6. Non existence of statistically significant differences in the significance level (0.05) in average(1.019), between average answers of female students on the scale of self-harm and its subsidiary dimensions resulting from birth order (elder, middle and young). 7. The existence of statistically significant differences in the significance level of (0.05) in average(1.317), between average answers of elder female students and younger female students in favor of elder female students.
