Abstract Empathy accuracy and personality traits are key predictors of relationship satisfaction, however it is not clearly examined in the past studies. This study was conducted to see the relationship between the empathy accuracy and relationship satisfaction while personality traits was the moderator. This study had 35 couples (35 males, 35 females) in total, 14 couples were excluded because they did not complete the emotion ratings section. A cross correlation test was used to correlate the emotion ratings of both partners. A PROCESS in SPSS 24 was used to test whether personality traits moderate the association between empathy accuracy and relationship satisfaction. Results show a non-significant relationship between empathy accuracy and relationship satisfaction, as well as personality traits and relationship satisfaction. The null hypothesis is accepted.
