Abstract: Objective: To explore and describe the experience of Post Traumatic Growth of parents of children with rheumatic diseases. Methods: Phenomenological research methods and semi-structured individual interviews were used to get a clear understanding of the experience of the parents' post traumatic growth. And 10 parents whose children were diagnosed as rheumatic diseases were recruited to have semi-structured interviews. Results: Through inductive thematic analysis, three themes were derived, including nine sub-themes. The key themes were the insights on life (treasure for life, new values as to life priorities, self adjustment to accept the reality), increased personal strength (self dependence, self enhancement), improved interpersonal relationship (greater sense of closeness and family togetherness, cherish the parent-child love, benefit from peer and other professional support, empathy and promotion of altruism). Conclusion: The experience of post traumatic growth of parents can be used as a breakthrough point to explore the growth potential of children's parents after trauma, and ultimately improve the PTG level of children's parents.
