Problem Identification: Many cancer patients experience posttraumatic growth (PTG), and psycho-oncologists are exploring ways to facilitate PTG through psychosocial intervention. This study utilized a scoping review protocol to provide a comprehensive evaluation of psychosocial interventions aiming to promote PTG in oncology. Literature Search: Three databases were used to identify empirical studies implementing psychosocial interventions to promote PTG in cancer patients, according to Calhoun and Tedeschi's Posttraumatic Growth Inventory. Data Evaluation: Two independent reviewers screened articles for inclusion and extracted data for qualitative synthesis. 8275 abstracts and 116 full-text articles were assessed, with 33 studies included in this review. Conclusions: Common treatment components of psychoeducation, peer support, and mindfulness skills identified by this review may be considered for future interventions targeting post-traumatic growth. The results of this review also identified areas where PTG research may be strengthened, including standardized reporting of PTG outcomes and cancer-related variables.
