Cancer-related posttraumatic growth and posttraumatic stress: how are they connected and what are their correlates?

Abstract

Cancer is a stressful life event that can lead to specific posttraumatic reactions. Posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) are two main posttraumatic reactions that are related to each other, and both have different correlates. The linearity of the relationship between PTG and PTSS and the different socio-demographic, cancer-related, emotional, and psychological correlates were analyzed in patients with cancer (N = 126). The relationship between PTG and PTSS was found to be more curvilinear than linear. PTSS was more strongly related to psychological factors (e.g., anxious preoccupation, hope-helplessness, and resilience) while PTG was strongly related to existential factors (e.g., self-transcendence and religiosity). The results show that cancer-related PTSS and PTG are specifically related constructs which are related differently to particular correlates. Specifically, the greatest differences were observed in the psychological variables. In the early phases, therapeutic interventions focused on variables related to PTSS can lead to the reduction of PTSS. In follow-up phases, the therapeutic intervention focused on the increase of the level of variables related to PTG can help the development of PTG.
