This study evaluated the prevalence and predictors of long term posttraumatic growth (PTG) after breast cancer, and relationships of PTG with psychological health in a random sample of 307 currently disease-free women 5-15 years after diagnosis. This cross-sectional study reveals long term posttraumatic growth scores comparable to those found in shorter term studies. Prevalence of a better appreciation of life is especially noteworthy. With the exception of perceived current sequelae of disease associated in a somewhat curvilinear fashion with PTG, demographic and medical variables are poor predictors of the issue. On the contrary, dispositional positive affectivity and adaptative coping of positive, active, relational, religious and to some extent denial coping have a strong effect on growth. Finally, PTG is slightly associated with mental quality of life and happiness. Findings are discussed in the light of posttraumatic growth theory.
