The purpose of this study was to determine the student`s behavioral responses toward to sexual harassment from patients and the consequential effects on patient-student relationship in the psychiatric unit. The subjects of this study were 147 nursing students selected from 2 junior colleges and 2 nursing colleges. The data were collected by means of a self-reported questionnare from Sep. 22 to Dec. 30, 1994. Data analysis included percentage, priority order, one-way ANOVA. The results were as follows : The most frequently reported means of harassment was physical touch, sexual innuendo, over exhibition, etc. The behavioral responses were classified 5 types. Most of students responded by verval and physical limitation and passive behaviors such as escape from that situation and patience. The students responsed differently according to severity and type of sexual harassment. By these, 49.1% of all cases stopped sexual harassment. But there are only 1 desirable case. The other patients were withdrawn or not really understood. Clearly expressive response was most desirable effect on the patient-student relationship. These results suggest that the students should be taught more practical and concrete coping skill for sexual harassments.
