The purpose of this study is to explore practical ways to support university students who had relational
loss experience such as parents divorce, breakup, broken heart, cessation of friendship by identifying the
relational between social support perceived by university students who had relational loss experience,
deliberate rumination and posttraumatic growth and by verifying the mediating effect of deliberate
rumination on the relational between social support and posttraumatic growth. To achieve this, 1,750
university students in Busan and Gyeongnam area were surveyed. This study finally analyzed the data of
314 students those who were in post-adolescence aged 19 to 24 and replied that the most traumatic event
was relational loss experience and reported that subjective severity at the time of the incident was more
than above average. In the data analysis, structure equation modeling analysis according to the two-step
approach was conducted and bootstrapping method was applied for verification of mediating effect.
According to the study, social support has a significant impact on the deliberate rumination and deliberate
rumination has significant impact on posttraumatic growth. In addition, social support has a significant
impact on posttraumatic growth and deliberate rumination was found to partially mediate the relational
between posttraumatic growth and social support. Based on these results, this study discussed practical way
to deal with posttraumatic growth of university students who had relational loss experience.
