Among their various experiences of loss, a broken heart is thought to be familiar to young people and relatively easy to experience. This experience greatly influences adolescents’ values and their life. In this study, we aimed to examine the effect of differences in attachment style on meaning making in adolescents’ broken-heart experiences. Questionnaires were distributed to 354 university students. In total, 312 people were analyzed after excluding incomplete responses. The results show no significant difference in meaning making or feelings of self-growth in the group with broken-heart experience. The subjects of this study were relatively healthy adolescents; therefore, their attachment styles were conceivably concentrated on the average value. The group with broken-heart experience was compared with the group without broken-heart experience and a significant difference was observed in “focus on positive aspects.” The score of the group with broken-heart experience was significantly higher than the score of the group without broken-heart experience. It is suggested that adolescents should overcome the stressful experience of a broken heart during their interpersonal relationships by positive meaning making, regardless of the attachment style.
