Previous research papers on gender relation have pointed out that women, under social expectation, in physical structure and type of build, are disadvantaged and tend to be the victims in date violence. Young girls, who tend to be weaker in terms of independent and mature personalities and lack of handling interpersonal relation, are the mostly likely group of date violence. Past researchers had focused mostly on actual date violence experiences and there is no domestic empirical research on date violence tolerance available when this study is conducted. The purpose of this study is to, via questionnaires, explore the tolerance of college girls on date violence and actual experiences in different types and degrees. From the explorations of past researches, the researcher selects self-esteem, violence causal belief, gender role attitude and other violence experiences (including domestic violence and peer violence) as independent variables and date violence tolerance and actual experiences as dependent variables. The sampling population of this study is girls at five-year, two-year, four-year and two-year technology of a selected college of commerce in Taipei City in stratified random sampling selection with class as sampling unit. A total of 424 girls are included in the formal survey and 405 valid questionnaires collected. From the statistics, it is found that there are around twenty percent of girls reported a certain degree of tolerance of date violence, although the endurance is different in different types of date violence. Around ten percent of girls have date violence experiences, accounting for one fifth of those having going steady experiences. Degree of tolerance of date violence is more affected by value belief variables than basic demographic nature. Date violence influential factors are more affected by basic demographic variable. When respondents have higher identification of their own gender role and traditional social expectations, they have fewer attitudes on positive violence belief (violence empirical reference). The lower grades the girls are in, the lower self-esteem and higher tolerance of date violence they report. Girls with more dating experiences, fewer peer violence, lower fathers’ education attainment, and in lower grades have more date violence experiences. After cross proof between the findings in this research and past empirical results, the research proposes a few conclusions: First, the overall population rate of college girls’ date violence experiences is lower than that in the U.S.; that of girls having fixed boyfriends is comparable to that in the U.S. The percentage of enduring partial date violence is slightly higher than the ratio of victims. The two groups of girls have differences. Violence tolerance is only lowly correlated to the actual experiences. Prediction factors of date violence tolerance and date violence experiences prediction factors are different. Based on the preceding conclusions, the research points out that, in preventive measures of date violence, we tended to pay more attention to the potential victims to break the date violence myths by case counseling to enhance values. This may help reduce date violence tolerance but not necessarily reduce the actual victim experiences. In practice, it is suggested we should emphasize the influence of peer violence on adolescents. We also need to enhance the handling skills of junior school girls in intimacy relation and enhance the importance of peer support group in prevention. In the future, researchers can expand the sample size to understand the differences of two genders’ tolerance of date violence. In-depth research in qualitative method can be conducted on influence mechanism of mothers’ education attainment and peer violence experiences on date violence tolerance and actual experiences.
