Abstract: Objective: To investigate the status and the correlations between physical restraint attitude and patients' aggressive behaviors perceived by psychiatric nurses. Methods: A total of 110 nurses from a psychiatric hospital in Shenzhen were investigated with the Perception of the Prevalence of Aggression Scale (POPAS) and Attitudes toward the Use of Restraints Scale(AURS). Results: The mean score of POPAS was 33.70±7.51, language aggression and mild physical violence were perceived most frequently by the nurses. The mean scores of AURS and all dimensions, named the legal and ethical issue, the feeling, the behavioral intentions about physical restraint, were 38.14±4.60,11.75±2.20,13.59±2.10,13.90±3.20,respectively. The correlation analysis showed that AURS score and the two dimensions, the feeling and the behavioral intentions about physical restraint were positively correlated with POPAS (r=0.24, 0.31, 0.20, P=0.036, 0.014, 0.047). Conclusion: Psychiatric nurses frequently suffered mild violence. Their attitudes towards restraints were neutral. There were positive correlations between nurses' physical restraint attitudes and their perceived patients' aggressive behaviors. Nurse Managers should pay attention to nurses' physical and mental health, and provide training program to change nurses' attitudes about physical restraint, help them identify patients' aggression effectively, and take alternative interventions immediately to reduce the use of physical restraint.
