This measurement consisted of two reflections; the first is the father and the second, the mother. Each reflection contained (33) items distributed among five dimensions of the parental psychological abuse (Rejection, Verbal abuse, Social isolation, Intimidation and emotional negligence). These measurements proved to enjoy a considerable degree of validity and reliability through the extraction of its apparent validity and reliability by using (Cronbach's Alpha). The findings were analyzed using the Statistical Package of Social Sciences (SPSS) using Means Average, Standard deviations, person's correlation co-efficiencies, T-test and ANOVA. One of the most significant findings that this study reached is that the 12th grade student had seldom experienced parental psychological abuse during their childhoods. The findings of the study also demonstrated the existence of a statically significant negative correlation relationship between the students' academic attainment and the parental psychological abuse in it's five dimensions. However the dimension intimidation had the weakest negative correlation with academic attainment. The findings also indicated the existence of statistically significant differences between boys and girls in parental psychological abuse except the dimension of cinotional negligence where the findings of the study did not reveal any statistically significant differences. The findings also revealed the existence of statistically significant differences between the father's educational level in favour of fathers who do not master reading and writing. On the other hand, the findings revealed that there are no statistically significant differences between the educational level of the mother. The study also indicated that the middle son is the one who is mostly exposed to parental psychological abuse. It also showed that the more the number of the family members, the more likely its children are exposed to parental psychological abuse.
