The purpose of this study is to confirm the relationship between emotional abuse, gender sensitivity, and adult attachment, and to verify the mediating effect of adult attachment in the relationship between emotional abuse experiences and gender sensitivity. Therefore, this study hypothesizes that the experience of emotional abuse in childhood and adolescence will have a significant effect on gender sensitivity, and that adult attachment anxiety and avoidance of adult attachment will mediate the relationship between emotional abuse experience and gender sensitivity in childhood and adolescence. To verify this, a total of 300 adults aged 20 to 39, 150 males and 150 females, were surveyed. Frequency analysis was conducted to identify the demographic information of the collected data, and descriptive statistical analysis was conducted to ensure that the collected data followed a normal distribution. In addition, reliability analysis was conducted to confirm the internal agreement (Cronbach’s a) of the measurement tools, and Pearson’s correlation analysis was conducted to examine the correlation between variables. Finally, to verify the structural model, the structural equation model was used to confirm the model fit and the causal structure between variables, and the indirect effect of each parameter was confirmed using a phantom variable. In addition, multigroup confirmatory factor analysis and multigroup path analysis were verified to confirm the difference between men and women. As a result of the study, first, the relationship between emotional abuse experience and gender sensitivity in childhood and adolescence was not significant. Second, experiences of emotional abuse in childhood and adolescence showed a significant positive correlation between adult attachment anxiety and adult attachment avoidance. Third, adult attachment anxiety and adult attachment avoidance were positively and negatively correlated, respectively. Fourth, it was found that adult attachment anxiety and adult attachment avoidance had a mediating effect in the relationship between emotional abuse experience and gender sensitivity in childhood and adolescence. Fifth, the relationship between emotional abuse experiences in childhood and adolescence, adult attachment and gender sensitivity was found to be statistically insignificant. Through the results of this study, it was confirmed that the experience of emotional abuse in childhood and adolescence did not affect gender sensitivity, and it was proved that adult attachment anxiety decreased gender sensitivity and adult attachment avoidance was a mediator that increased gender sensitivity. Through this, it is meaningful to prove that it is helpful to explore the client's child/adolescent abuse experiences and adult attachment types when counseling clients complaining of gender issues.
