ABSTRACT The study of posttraumatic growth (PTG) has burgeoned over the last decade, particularly in the area of oncology. The aims of the study were to: (1) describe PTG in patients with hepatobiliary carcinoma, (2) examine agreement between the patient and caregiver measures of patient PTG, and (3) test the associations between PTG and other psychological factors and clinically relevant outcomes.
Two hundred and two patients with hepatobiliary carcinoma completed a battery of standardized questionnaires that measured PTG, depressive symptoms, optimism, expressed emotion, and quality of life (QOL). A subsample of family caregivers also completed ratings of patient PTG, using the Posttraumatic Growth Inventory (PTGI), as well as their own PTG.
No significant increase in the patients' PTG was observed between diagnosis and 6-month follow-up with the exception of the Relating to Others subscale of the PTGI. PTG was not found to be associated with QOL or depressive symptoms. At diagnosis, the agreement between the patients' PTG and family caregivers' rating of patient PTG was found to be high (ICC=0.34-0.74, p=0.001-0.05). PTG was found to be significantly associated with optimism (r=0.20 p=0.02-0.05) and traumatic life events reported in the past 3 years, including recent losses (F(1, 52)=6.0, p=0.02) and severe physical injury (F(1, 52)=5.5, p=0.02). Caregivers reported PTG as a result of their loved one's diagnosis of cancer.
Preliminary results suggest that PTG is relatively stable over the first 6 months after diagnosis and changes as a result of a diagnosis of cancer were reported, and possibly observed, by others. Family caregivers also experience PTG as a result of their loved one's diagnosis of advanced cancer.

    ABSTRACT: Posttraumatic growth (PTG) is viewed as a positive psychological change resulting from a struggle with trauma. A number of trauma-related factors have been proven effective in predicting PTG; however, the effects of pretrauma psychological factors on PTG have not been adequately evaluated (e.g., using a prospective design). This prospective study examined the effects of pretrauma psychological factors (e.g., coping styles, prior trauma) on PTG. In total, 810 Taiwanese undergraduate students were recruited for a baseline survey (Time 1), among whom 592 completed a survey 2 months later (Time 2). Data from 110 participants who had experienced trauma between Time1 and Time 2 were used for analysis. Among the pretrauma factors examined at baseline, only rumination and distractive style were positively correlated with PTG. The posttrauma factors based on Calhoun and Tedeschi's model (i.e., core belief challenge, deliberate rumination, and social support) were also positively correlated with PTG. A hierarchical regression analysis showed that pretrauma coping styles had an incremental effect on PTG beyond posttrauma predictors. Deliberate rumination signifciantly mediated the relationship between pretrauma rumination and PTG. These findings highlight the role of pretrauma psychological factors in PTG and present further support for Calhoun and Tedeschi's model of PTG.

    ABSTRACT: Much of the research on post-traumatic growth posits that traumatic events may result in positive personality changes in a number of domains. We propose that this growth may occur, at least in part, because of changes in situations that one experiences following a traumatic event. Exposure to these new situations may be directly responsible for changes in individual behaviour and personality. We explore how new situations may be relevant to the study of post-traumatic growth and recommend that future research consider differences in experienced situations.

    ABSTRACT: Objective Posttraumatic growth at end of life, a positive psychological consequence of dealing with a life crisis, may be catalyzed by the trauma of facing mortality. Studies on cancer patients' posttraumatic growth have overwhelmingly examined early-stage survivors. Of the few studies on advanced cancer patients, none anchored posttraumatic growth with the patient's death. Therefore, the purposes of this study were to describe longitudinal changes in and to identify determinants of posttraumatic growth over the dying process.MethodsA convenience sample of 313 cancer patients was recruited and followed until death. Posttraumatic growth was measured by the Posttraumatic Growth Inventory. Determinants were evaluated from sociodemographics, cancer characteristics, social context variables, and coping strategies using a multiple linear regression model.ResultsThe dying process may be too threatening and stressful for cancer patients to experience profound posttraumatic growth as manifested by low Posttraumatic Growth Inventory scores (26.13 ± 21.59 to 40.33 ± 27.71 on a 0–105 scale) without significant changes as death approached. However, terminally ill cancer patients who were not defeated by the initial threat of death experienced posttraumatic growth. Patients were at risk for low-level posttraumatic growth if they were male, were non-middle aged, had low educational attainment, had a non-metastatic disease, recently recognized terminally ill status, had severe symptom distress, had high functional dependence and weak social support, and were unaware or had low acceptance of their prognosis.Conclusion Interventions are needed to appropriately relieve symptom distress, facilitate functional independence, enhance social support, and improve prognostic awareness and acceptance to inspire positive changes for cancer patients at end of life.
