Links between violence, aggression, and mental illness are well documented. Despite this association, our current understanding of the factors for and optimal treatment of aggression remains limited. This lack of knowledge is alarming because nurses, particularly pediatric nurses who treat aggressive children, are frequent targets of patient aggression. Consequently, the aim of this article is to provide information regarding the concept of aggression in child patients, assessment of violent behavior, implementation of interventional treatment and a review of medical, psychological and social strategies which assist in the understanding of aggression and its clinical intervention. However, the etiology of aggression for the most part still remains a mystery.

Background & Aim: Privacy is one of basic rights of the patients. Privacy becomes important for the adolescents when they hospitalize in an unfamiliar environment. This study aimed to compare the perceptions of inpatient adolescents with nurses on the observance of privacy and its importance.

Methods & Materials: In this cross-sectional study, 175 nurses and a convenience sample of 180 inpatient adolescents who had met the inclusion criteria were recruited to the study. Data was gathered using a questionnaire. Man-whitney u and kruskal-wallis statistical tests were used to analyze the data.

Results: The results showed that there was significant differences between nurses&apos and inpatient adolescents` perceptions on the observance of privacy and its importance (man-whitney u, P<0.001). The most important priority regarding the privacy from nurses&apos point of view was "covering the unnecessary parts of the body while caring" whilst it was "providing a pleasant decorated environment, telephone, toilet and bath in room, and hospitalization in a room with peers" from the adolescents&apos point of view. The most observed case about privacy from the nurses&apos point of view was "taking immediate action to help the teenagers if necessary" whilst, from the adolescents view, it was "calling them with their favorite names".

Conclusion: The mean perceptions of nurses were higher than the adolescences toward observance of privacy and its importance. The results can guide nurses to improve quality of care for this group.
