Abstract
Posttraumatic growth (PTG) offers an alternative understanding of trauma response, contrasting with traditional perspectives focused solely on symptom development and resilience. In the PTG model, individuals and groups report positive changes in life philosophy, self-understanding, and interpersonal relationships because of successfully navigating the struggles involved with experiencing adversity. This narrative review includes the evolution of PTG theory, highlighting the disruption of core beliefs, the role of rumination, and the reconstruction of a life narrative as central mechanisms of the PTG process. The authors describe the five empirically validated domains of PTG and outline the naturally occurring PTG process. Methods are discussed for facilitating PTG through "expert companions," who may be peers or professionals providing nonjudgmental, supportive relationships that encourage emotional regulation, constructive disclosure, and meaning making. The article explores how these methods can be applied to individuals, communities, and organizations, all of which may experience comparable domains of growth following collective adversity. The article concludes by highlighting how a focus on posttraumatic growth shifts perspectives from viewing trauma survivors as broken to recognizing their potential for transformation and underscores the role of both professional and community support in fostering PTG and healthier organizational climates.
