Aim: This research was conducted to investigate the effect of emotion-focused approach training on improving interpersonal sensitivity in couples on the verge of divorce. Methods: The research method was quantitative and semi-experimental (pre-test-post-test design, with control group). The statistical population of the present study includes couples on the verge of divorce in Tehran province, regions 11 and 12, who are between the ages of 25 and 35 years old and have been selected voluntarily and based on the inclusion criteria for the study. The sample size of the study was 20 couples on the verge of divorce, who were selected by random sampling from couples on the verge of divorce who had referred to legal centers and counseling centers in Tehran for legal matters. The data collection tool was the interpersonal sensitivity questionnaire, and to test the research hypotheses, multivariate analysis of covariance was used with the assumptions (homogeneity of regression coefficients, linearity of the relationship between variables, normal distribution of the studied characteristic, homogeneity of variances). Findings: The results of the study indicate that the dimensions of interpersonal sensitivity (interpersonal awareness, need for approval, separation anxiety, shyness, and low self-esteem) in couples on the verge of divorce who received emotion-focused approach training were lower than those in couples who did not receive this training. Conclusion: The results of this study indicate that the emotion-focused approach training program had a significant effect on improving interpersonal sensitivity in couples on the verge of divorce and could be considered as an effective training program by psychologists and counselors.
