Traumatic events such as health problems, accidents, death, divorce, deceit, harassment, rape etc. of individuals or their close relatives can lead to positive or negative effects on individuals. Posttraumatic growth is a concept that deals with the positive changes and transformations that individuals experience in their relationships, self-perceptions, and life philosophies after the traumatic events that have passed through their heads. The transformation of the individual after the traumatic event is influenced by personality traits, spiritual emotions, perspective on life, culture etc. In this context, it has been a wonder that the concept of spiritual well-being, which plays an important role in the value judgments of the individual, which is influential on behavior and meaning of life of the individuals, has an effect on post-traumatic growth. In this study by determining the levels of post-traumatic growth and spiritual well-being of individuals who experienced a traumatic event, the effects of spiritual well-being of individuals on post-traumatic growth were investigated. As a result of the study, it was found that the level of spiritual well-being affected the posttraumatic growth of individuals. It has been concluded that individuals' respect for individuals, living in harmony and believing in the existence of a transcendent power have a positive effect on the level of development after the traumatic event. As a result of the study, it has been determined that individuals who have a health problem show more development in terms of expressing their feelings, exhibiting positive attitudes in interpersonal relations and understanding the value of life compared to individuals who are exposed to other traumatic events. Finally, after the trauma experienced by individuals, it has been revealed that they show development and change in the belief system the most according to the study.
