A Descriptive correlational design was used to achieve the purpose of this study. Setting: primary schools in Qaliubiya Governorate, which are affiliated to the Ministry of Education. Subject: Multistage random sample of 600 students were selected from primary schools in Qaliubiya Governorate. Instruments of data collection:  Two instruments were used; one instrument was used to assess perceived parenting styles. Another instrument was used to assess behavior problems among school age children. Results: Lying was highly present between 32.3% of children, harassment and teasing was moderately present between 31.2% of them and stealing was moderately found between 27% of children.
