Objective: The purpose of this study was to explore the effect of gender education on improving chronic schizophrenics's perspectives about gender. Methods: This study used a quasi-experimental nonequivalent pretest-posttest control group design. Using convenience sampling, 99 participants with chronic schizophrenics were selected from a sanatorium institution in southern Taiwan and divided into an experimental group (n=43) and a control group (n=56). The experimental group was assigned to a 8 sessions of gender education. The control group participated in routine activities. This gender relations questionnaire was used to assess participants' perspectives about gender. Then, descriptive statistics, chi-square test, paired sample t test, independent sample t test, and McNemar changing significance test were used for data analysis. Results: There were significant differences in the degrees of disability (p=.006) and age (p=.024) between the experimental and control groups. The participants showed significant differences on pretest perspectives about gender between the experimental and control groups (t=-3.301, p=.001); After 8 sessions of gender education, there were no significant differences on posttest perspectives about gender between the experimental and control groups (t=-.252, p=.802). Gained scores in the experimental group were significantly higher than the control group (t=4.160, p<.001). The correct perspectives about gender of the experimental group could be attributed to the intervention of gender education program. Conclusion: The results showed that gender education program could improve the perspectives about gender of chronic schizophrenics. The results could be regarded as a reference on promoting gender education for chronic schizophrenics in psychiatric sanatorium institutions.
