Functional significance of posttraumatic growth in U.S. military veterans.

BACKGROUND: Although many studies indicate that individuals who have experienced a traumatic event can experience posttraumatic growth (PTG), some researchers have questioned the significance of PTG in associations with functioning. The role of PTG in functioning following trauma may be better elucidated by accounting for its joint effects with posttraumatic stress disorder (PTSD) symptoms. METHODS: Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 3847 trauma-exposed U.S. veterans. Participants completed assessments of potentially traumatic events, PTSD symptoms, and PTG, as well as a broad range of sociodemographic, military, trauma, health, personality, and psychosocial characteristics. RESULTS: PTG was independently and moderately associated with higher mental, cognitive, and psychosocial functioning, but not physical functioning. Results showed a similar pattern of findings when examining relations between subdomains of PTG and these aspects of functioning. Additionally, among veterans who screened positive for PTSD, those who endorsed PTG reported higher levels of mental, cognitive, and/or psychosocial functioning than those who did not endorse PTG. LIMITATIONS: Findings may be limited by the use of a cross-sectional design, retrospective self-reports of PTG, and a predominantly older white male veteran sample. CONCLUSION: Results provide support for the functional significance of PTG and highlight the importance of considering PTSD symptoms to better understand the role of PTG in functioning. Clinical interventions to foster PTG may help promote post-trauma functioning.

Posttraumatic Growth in U.S. Military Veterans: Results from the National Health and Resilience in Veterans Study.

Despite increasing recognition that positive psychological changes or posttraumatic growth (PTG) may develop after highly stressful or traumatic events, contemporary population-based data on the epidemiology of PTG in high-risk samples such as U.S. military veterans are lacking. Additionally, in light of emerging evidence suggesting an 8-factor model of posttraumatic stress disorder (PTSD) symptoms, an up-to-date characterization of how these symptom clusters relate to PTG can help inform efforts to help promote PTG. Data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study (NHRVS), which surveyed a nationally representative sample of 3,847 trauma-exposed U.S. veterans. Participants completed assessments of potentially traumatic events, PTSD symptoms, and PTG, as well as a broad range of sociodemographic, military, trauma, health, personality, and psychosocial characteristics. Results revealed that 63.2% of trauma-exposed veterans and 86.4% of veterans who screened positive for PTSD endorsed moderate-or-greater PTG; these prevalences are higher than those reported in an independent U.S. veteran sample in 2011 (50.1% and 72.0%, respectively). An inverted U-shaped association was observed between PTSD symptom severity and PTG levels, with scores of 31 to 51 on the PTSD Checklist for DSM-5 associated with the highest likelihood of PTG. Intrinsic religiosity and internally- and externally-generated intrusive symptoms of PTSD were identified as the strongest correlates of PTG. Results suggest that prevention and treatment efforts to mitigate severe PTSD symptoms, and help promote intrinsic religiosity, and more deliberate and organized rumination about traumatic experiences may help foster PTG in veterans.

Moral injury in post-9/11 combat-experienced military veterans: A qualitative thematic analysis.

War zone exposure is associated with enduring negative mental health effects and poorer responses to treatment, in part because this type of trauma can entail crises of conscience or moral injury. Although a great deal of attention has been paid to posttraumatic stress disorder and fear-based physiological aspects of trauma and suffering, comparatively less attention has been given to the morally injurious dimension of trauma. Robust themes of moral injury were identified in interviews with 26 post-9/11 military veterans. Thematic analysis identified 12 themes that were subsumed under four categories reflecting changes, shifts, or ruptures in worldview, meaning making, identity, and relationships. Moral injury is a unique and challenging clinical construct with impacts on the individual as well as at every level of the social ecological system. Recommendations are offered for addressing moral injury in a military population; implications for community public health are noted. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Pandemic-related posttraumatic psychological growth in U.S. military veterans: A 3-year, nationally representative, longitudinal study.

Little is known about the positive psychological changes or posttraumatic growth (PTG) in response to the pandemic as the COVID-19 vaccines has become widely available. This longitudinal study aimed to characterize changes in the prevalence of pandemic-related PTG, and to identify and quantify the relative importance of PTG correlates pre-pandemic, 1- year peri­pandemic, and 2-years post-pandemic onset. A total of 2,441 U.S. military veterans completed Wave 3 assessment of the National Health and Resilience in Veterans Study. In the full sample, a significant decrease from peri­pandemic to 2-years post-pandemic onset was observed in overall pandemic-related PTG (41.5% to 32.2%) and four domains of PTG (appreciation of life, relating to others, personal strength, spiritual changes). Among veterans who screened positive for pandemic-related posttraumatic stress symptoms, the prevalence of pandemic-related PTG was markedly higher and did not change from peri­pandemic to 2-years post-pandemic onset (78.4% to 73.4%). Greater pre-pandemic PTG (personal strength and new possibilities) and greater worries about the effect of pandemic on one's mental health were the strongest correlates of pandemic-related PTG 2-years post-pandemic onset. Results suggest that psychosocial interventions to bolster PTG in relation to early life traumas may help facilitate PTG in response to the pandemic and related crises.

Shared trauma, resilience, and growth: A roadmap toward transcultural conceptualization.

Objective: Countless communities worldwide are exposed directly and subsequently to the effects of massive-scale collective stressors, from natural disasters to human-caused. In contexts of collective adversity, health care providers who are also members of these communities share and interdependently affect the range of responses their patients have. We aim to conceptualize this spectrum, termed shared trauma, shared resilience, and shared growth. Method: In this metasynthesis, we review the literature on these underacknowledged dynamics globally. We include prior conceptualizations of direct and indirect trauma, collective trauma, cultural context, and the COVID-19 pandemic toward clearer conceptualization of shared mental health in global collective stressor contexts. Results: Most trauma and resilience research focuses on prevailing concepts and measures with questionable cross-cultural applicability. These works usually center on acute, highly distressing threats to physical safety at the individual level. The scarce literature on shared trauma describes it as a rare phenomenon, entailing conflicting messages of narrative accounts within contexts of few cultures with medium to high degrees of individualism. There has been little consideration of other non-Western and indigenous communities with more collectivist values and collective trauma histories. There is limited understanding of these concepts as they pertain to the vast majority of cultures. As a result, shared trauma, resilience, and growth have been poorly conceptualized, differentiated, or empirically researched. Conclusions: We propose uniquely inclusive models of shared trauma, resilience, and growth. These models reflect the cumulative effects and interplay of direct to indirect, acute to chronic, individual to collective, and historic to transgenerational factors influenced by cultural context.

A short form of the posttraumatic growth and posttraumatic depreciation inventory - expanded (PTGDI-X-SF) among German adults.

BACKGROUND: After experiencing trauma, people often report both negative and positive changes, which can be operationally defined as posttraumatic growth (PTG) and posttraumatic depreciation (PTD). However, there is no brief measure for assessing both posttraumatic changes simultaneously. OBJECTIVE: This study describes the short form of the expanded version of the Posttraumatic Growth and Depreciation Inventory (PTGDI-X-SF) among German Adults. METHOD: Using a sample of 253 German adults, the dimensionality of the PTGDI-X-SF was examined by confirmatory factor analyses. Internal consistencies were determined. The relation of PTG and PTD was investigated. Regression analyses explored the relationships to established predictors as previously found for the full-scale version of the PTGDI-X. RESULTS: Findings indicate a 5-factor structure for the PTGDI-X-SF equivalent to the PTGDI-X as well as high reliability for PTG (α = .88) and PTD (α = .88). Participants reported more PTG (M = 2.53, SD = 1.20) than PTD (M = 1.41, SD = 1.16). PTG and PTD were weakly associated (r = -.148, p = .018). PTG was positively related to disruption of core beliefs (ß = .25, p < .001) and deliberate rumination directly after the trauma (ß = .38, p < .001). PTD was positively associated with recent rumination irrespective of whether it was intrusive (ß = .21, p < .05) or deliberate (ß = .33, p < .01). CONCLUSIONS: Overall, results support the applicability of the PTGDI-X-SF as a valid and efficient measure to assess PTG and PTD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Posttraumatic growth-oriented peer-based training among U.S. veterans: evaluation of post-intervention and long-term follow-up outcomes.

Introduction: Exposure to trauma among U.S. military veterans occurs at a high rate, often resulting in continued difficulty with emotional adjustment and a diagnosis of posttraumatic stress disorder (PTSD). The present study provides data from 184 U.S. military veterans who completed a manualized posttraumatic-growth oriented training program during an integrative seven-day retreat. Methods: Data was collected at baseline, after program completion, and at 18-month follow-up. Results: Results on primary outcomes indicated significant increases, with medium to large effect sizes, in growth related outcomes. Specifically, there was a significant increase in scores by 54% on the posttraumatic growth outcome measure (PTGI-X) from baseline (M = 50.2, SD = 31.1) to endpoint (M = 77.4, SD = 29.6), t(183) = -8.78, p < 0.001. Also, results indicate that immediately following training (Day 7), participants reported a significant decrease of 49% on the PCL-5 from baseline (M = 39.7, SD = 17.6) to endpoint (M = 20.1, SD = 13.2), t(183) = 11.75, p < 0.001. Depression subscale scores decreased by 60% from baseline (M = 8.0, SD = 5.2) to endpoint (M = 3.2, SD = 3.0), t(183) = 10.68, p < 0.001; Anxiety scores decreased by 28% from baseline (M = 5.8, SD = 4.3) to endpoint (M = 4.2, SD = 3.5), t(183) = 4.08, p < 0.001; and Stress scores decreased by 50% from baseline (M = 10.0, SD = 4.4) to endpoint (M = 5.0, SD = 3.3), t(183) = 12.21, p < 0.001. Eighteen-month follow-up data was available for 74 participants and indicated that all significant changes in growth-related outcomes were maintained. Further, all significant changes in symptomatology-related outcomes were also maintained at follow-up. Discussion: These findings demonstrate both the immediate and the long-lasting impact of an integrative posttraumatic growth-oriented training program on psychological growth and PTSD symptom reduction among U.S. military veterans.

Coping and rumination as predictors of posttraumatic growth and depreciation.

PURPOSE: The present study examined the joint impact of coping and rumination after trauma on posttraumatic growth (PTG) and posttraumatic depreciation (PTD) based on the PTG model. METHODS: A cross-sectional study was conducted between October 2017 and May 2018. A sample of 253 individuals who had experienced a traumatic event in the last two years, was included. Participants completed an online self-reported survey, including demographic variables, trauma characteristics, the German Posttraumatic Growth and Depreciation Inventory - Expanded, the Brief COPE Inventory, and the Event Related Rumination Inventory. An analysis of correlation, a principal component analysis and hierarchical regression analyses were conducted. Statistical analyses were undertaken on SPSS (version 25.0; IBM, New York, USA). RESULTS: After controlling for the effects of personal and trauma characteristics, self-sufficient coping and socially supported coping were found to favor the emergence of PTG. Event-related and recent deliberate rumination were positively related to PTG. Avoidant-focused coping and recent intrusive rumination were positively associated with PTD. Overall, the final models accounted for 46% and 58% of the variance in PTG and PTD. CONCLUSION: Our findings confirm the PTG model and support the central role of deliberate rumination, self-sufficient coping and socially supported coping in the development of PTG. Our results indicate that a similar model of PTD with comparable influencing factors can be assumed: if the individual is stuck in ongoing intrusive rumination and uses more avoidance-focused coping, it might lead to more reports of PTD.

The Chinese version of Posttraumatic Growth and Depreciation Inventory-Expanded version (PTGDI-X) for cancer survivors.

Many patients with cancer report positive changes often referred to as posttraumatic growth (PTG). Some of these self-reported PTG may represent maladaptive illusions created by individuals to cope with the illness. A recently established Posttraumatic Growth and Depreciation Inventory - Expanded version (PTGDI-X) includes both PTG and posttraumatic depreciation (PTD) items. This inventory may provide a more balanced picture of the phenomenological world of cancer survivors. We examined the Chinese version of the PTGDI-X's applicability to cancer patients, and how PTG and PTD were related to posttraumatic stress symptoms. Two hundred sixty-five cancer survivors in Taiwan completed the Chinese version of the PTGDI-X, along with the PTSD Checklist for the DSM-5 to measure posttraumatic stress disorder (PTSD) symptoms. Confirmatory factor analysis showed that the factor structure of the PTGDI-X established in a multi-national study fit our data from cancer patients modestly well. The PTD score had a significant and positive correlation with PTSD symptoms, whereas the PTG and PTSD showed a significant curvilinear relationship in the form of an inverted U-shape. This study's results indicate that PTG and PTD are separated constructs with differential relationships with cancer outcomes. The Chinese version of the PTGDI-X is a viable instrument for psycho-oncological research. The PTD scores can provide useful information to guide cognitive interventions to reduce distorted cognitions. In contrast, the PTG scores can provide further information on the phenomenological world of cancer survivors. In this study, clinical implications and future studies were considered.

The relation between emotion regulation choice and posttraumatic growth.

Previous research has examined emotion regulation (ER) and trauma in the context of psychopathology, yet little research has examined ER in posttraumatic growth (PTG), the experience of positive psychological change following a traumatic event. ER typically involves decreasing negative affect by engaging (e.g. reappraisal) or disengaging (e.g. distraction) with emotional content. To investigate how ER may support PTG, participants who experienced a traumatic event in the past 6 months completed a PTG questionnaire and an ER choice task in which they down regulated their negative emotion in response to negative pictures of varying intensity by choosing to distract or reappraise. Latent growth curve analyses revealed that an increase in reappraisal choice from low to high subjective stimulus intensity predicted higher PTG, suggesting that individuals who chose reappraisal more as intensity increased reported higher PTG. Findings suggest that reappraisal of negative stimuli following a traumatic event may be a key component of PTG.

An Item-Level Analysis of the Posttraumatic Stress Disorder Checklist and the Posttraumatic Growth Inventory and Its Associations With Challenge to Core Beliefs and Rumination.

Background: Previous studies have found that rumination and challenge to core beliefs may have a predictive effect on Posttraumatic Stress Disorder (PTSD) and Posttraumatic Growth (PTG) among different samples. In addition, there is some evidence that these variables have different effects on PTSD and PTG, although the latter construct has been the target of a larger body of research and theoretical models. The main objective of the current study is to examine the effect of challenge to core beliefs, intrusive rumination, and deliberate rumination on PTSD and PTG, through an item-level analyses. Methods: The sample was composed of 205 Portuguese women who had been given a breast cancer diagnosis (M = 54.32, SD = 10.05), and who completed the following self-administered questionnaires: the Posttraumatic Stress Disorder Checklist (PCL-C); the Posttraumatic Growth Inventory (PTGI); the Core Beliefs Inventory; and the Event Related Rumination Inventory. Two multivariate multiple regression analyses, using each item of the PCL-C and the PTGI as dependent variables, were conducted. Results: The results demonstrated that challenges to core beliefs predict 17 of the 21 PTGI items and 12 of the 17 PCL-C items. All but one item of the PCL-C are predicted by intrusive rumination, while the variance of only 4 items of the PTGI are explained by deliberate rumination. Conclusion: These findings indicate that women with breast cancer who tend to display higher levels of intrusive rumination are more likely to report PTSD symptoms, and that an examination of one's core beliefs is predictor of both positive and negative outcomes. In spite of the proven effect of challenge to core beliefs on both variables, this study suggests that this effect has only a minor influence on PTSD, in addition to confirming its major impact on PTG.

The effectiveness of a group intervention to facilitate posttraumatic growth among women with breast cancer.

OBJECTIVE: This longitudinal study tested the effectiveness of a group intervention designed to facilitate posttraumatic growth (PTG). METHODS: Sample consisted of 205 women diagnosed with non-metastatic breast cancer who were either assigned to an intervention group (n = 58) or to a control group (n = 147). PTG, challenge to core beliefs, and rumination (intrusive and deliberate) were assessed at baseline (T1), at 6 months (T2), and at 12 months after baseline (T3). RESULTS: Results from the Latent Growth Modeling suggested that participants from the intervention group have higher levels of PTG. The challenge to core beliefs and the intrusive rumination have a moderator role on PTG, since group intervention is also linked to the enhancement of both variables. CONCLUSIONS: Participation in the intervention group increase PTG. Challenge to core beliefs and intrusive rumination are improved by group intervention, which to a certain extent facilitate PTG.

The Posttraumatic Growth Inventory: A Revision Integrating Existential and Spiritual Change.

Spiritual Change (SC) is one of 5 domains of posttraumatic growth (PTG). The current Posttraumatic Growth Inventory (PTGI) assesses this area of growth with only 2 items, one focusing on religiosity and the other focusing on spiritual understanding. The addition of 4 newly developed spiritual-existential change (SEC) items, creating an expanded PTGI (Posttraumatic Growth Inventory-X), reflects a diversity of perspectives on spiritual-existential experiences that are represented in different cultures. Samples were obtained from 3 countries: the United States (n = 250), Turkey (n = 502), and Japan (n = 314). Analyses indicated that the newly added items capture additional experiences of growth outside traditional religious concepts, yet still are correlated with the original SC items, especially in the U.S. and Turkish samples. Relationships of the PTGI-X to established predictors of PTG, event-related rumination, and core beliefs, were as predicted in all 3 countries. The new 6-item SEC factor demonstrated high internal reliability, and the 5-factor structure of the expanded scale was supported by confirmatory factor analysis. The resulting 25-item PTGI-X can be used as a validated instrument in a wide range of samples in which traditional religious beliefs are less dominant.

Relating dispositional mindfulness, contemplative practice, and positive reappraisal with posttraumatic cognitive coping, stress, and growth.

OBJECTIVE: A growing body of theoretical and empirical work suggests that mindfulness may support more positive posttraumatic outcomes by reducing posttraumatic stress (PTS) and encouraging posttraumatic growth (PTG). Positive reappraisal (PR), a cognitive coping correlate of dispositional mindfulness (DM) has also been linked with greater PTG. However, neither DM nor PR have been modeled in relation to core posttraumatic constructs such as core belief disruption, intrusive rumination, deliberate rumination, PTS and PTG. METHOD: This study explored associations between these constructs in a sample of college students (N = 505), also investigating the impact of contemplative practice involvement on the relationships between the constructs. RESULTS: Results indicate that including DM and PR into established models of PTG increases the model's explanatory power, which distinct cognitive coping pathways connect DM and core belief disruption with PTS as well as PTG, and that contemplative practice involvement substantially alters relationships between the core PTG variables. CONCLUSIONS: The present study contributes to the growing reconceptualization of trauma as linked with both positive and pathogenic outcomes, emphasizing the need to better understand how posttraumatic cognitive coping strategies contribute to more positive outcomes.

The Posttraumatic Growth Inventory: Factor Structure and Invariance in a Sample of Breast Cancer Patients and in a Non-Clinical Sample.

The Posttraumatic Growth Inventory (PTGI) is frequently used to assess positive changes following a traumatic event. The aim of the study is to examine the factor structure and the latent mean invariance of PTGI. A sample of 205 (M age = 54.3, SD = 10.1) women diagnosed with breast cancer and 456 (M age = 34.9, SD = 12.5) adults who had experienced a range of adverse life events were recruited to complete the PTGI and a socio-demographic questionnaire. We use Confirmatory Factor Analysis (CFA) to test the factor-structure and multi-sample CFA to examine the invariance of the PTGI between the two groups. The goodness of fit for the five-factor model is satisfactory for breast cancer sample (χ2(175) = 396.265; CFI = .884; NIF = .813; RMSEA [90% CI] = .079 [.068, .089]), and good for non-clinical sample (χ2(172) = 574.329; CFI = .931; NIF = .905; RMSEA [90% CI] = .072 [.065, .078]). The results of multi-sample CFA show that the model fit indices of the unconstrained model are equal but the model that uses constrained factor loadings is not invariant across groups. The findings provide support for the original five-factor structure and for the multidimensional nature of posttraumatic growth (PTG). Regarding invariance between both samples, the factor structure of PTGI and other parameters (i.e., factor loadings, variances, and co-variances) are not invariant across the sample of breast cancer patients and the non-clinical sample.

Protocol for the psychotherapeutic group intervention for facilitating posttraumatic growth in nonmetastatic breast cancer patients.

BACKGROUND: Breast cancer can be perceived as a traumatic event with disturbing effects on psychological domains such as depression, anxiety, and Posttraumatic Stress Disorder. In contrast, growing evidence has shown that posttraumatic growth can occur as a result of coping with breast cancer. Challenging the assumptive world, deliberate rumination, and emotional disclosure are recognized as strong predictors of posttraumatic growth. Group interventions may also increase social support, distress disclosure, and posttraumatic growth. The aim of this study is to evaluate how group-based interventions can facilitate posttraumatic growth and promote improved psychosocial adjustment to breast cancer. This article describes the study protocol and the applied research methods. METHODS: To measure the impact of a group-based intervention on posttraumatic growth, a multi-center randomized control trial was developed for Portuguese breast cancer patients. 205 women with nonmetastatic breast cancer (stages 1 to 3) were recruited for the study and were randomly assigned either to the experimental group, which participated in an 8-session group intervention, or to the control group. Psychosocial variables, which consisted of posttraumatic growth, illness perception, stressfulness of the event, Posttraumatic Stress Disorder, core beliefs, rumination, social support, and distress disclosure were measured at three time points. The designated points in time for the assessments were baseline, 6 months post-intervention, and follow-up (12 months after baseline). DISCUSSION: This study is the first trial to assess the efficacy of a group-based intervention designed to facilitate posttraumatic growth following a breast cancer diagnosis. If proven to be effective, group-based intervention could be recommended as a complementary program to be included in hospital health-care and clinical practice. TRIAL REGISTRATION: The trial was registered on 28/10/2013 at the Current Controlled Trials ( ISRCTN02221709 ).

Core beliefs shaken by an earthquake correlate with posttraumatic growth.

Posttraumatic growth (PTG), psychological growth as a result of personal struggle with trauma, is hypothesized to occur when a highly stressful life event, such as a natural disaster, forces people to reexamine their core beliefs. To the authors' knoweldge, the present study is the first investigation in Japanese people examining the role of core beliefs, intrusive rumination, and deliberate rumination in PTG. Hypotheses that the level of reexamination of core beliefs, intrusive rumination, and deliberate rumination correlate with the seismicity of an earthquake and that the challenge to core beliefs is the major determinant of PTG were tested. Japanese undergraduate students who experienced the Great East Japan Earthquake on March 11, 2011 (N = 314) participated in this study and completed the Japanese version of the Core Beliefs Inventory (CBI), the Event-Related Rumination Inventory (ERRI), and the Posttraumatic Growth Inventory (PTGI). Results indicated that core beliefs were less likely to be challenged and that ruminations were less likely to be activated in Japanese people who were in the southern area with an approximate Richter magnitude of 4 or lower. PTG was more likely to occur when core beliefs were reexamined following the earthquake. Also, younger participants and those who recalled having engaged in both deliberate and intrusive rumination reported more PTG. Future studies should investigate which aspects of trauma can trigger or suppress the reexamination of one's core beliefs, for they are likely to be the major determinants of PTG, and should look at change longitudinally.

Posttraumatic growth, depression and posttraumatic stress in relation to quality of life in tsunami survivors: a longitudinal study.

BACKGROUND: Quality of life (QoL) may often be reduced in survivors of a natural disaster. This paper investigated how posttraumatic growth (PTG), depression and posttraumatic stress interact and independently predict QoL in a longitudinal study of disaster survivors. METHODS: A total of 58 Norwegian adults who were present in Khao Lak, Thailand at the time of the 2004 Southeast Asia Tsunami completed self-report questionnaires 2 and 6 years after the disaster. The participants reported symptoms of depression and posttraumatic stress as well as PTG and QoL. Multiple mixed effects regression analyses were used to determine the independent effects of PTG, depression and posttraumatic stress on QoL measured 2 and 6 years after the disaster. RESULTS: Posttraumatic stress and depression were negatively related to QoL. PTG was not significantly related to QoL in a bivariate analysis. However, considerable interaction effects were found. Six years after the tsunami, high levels of posttraumatic stress were related to lower QoL in those participants with low levels of PTG, whereas lower levels of depression were related to higher QoL in those participants with high levels of PTG. CONCLUSIONS: Posttraumatic stress and depression are negatively associated with QoL after a natural disaster. PTG may serve as a moderating factor in this relationship.

Trajectories of Posttraumatic Growth and Associated Characteristics in Women with Breast Cancer.

BACKGROUND: Cancer survivors may experience posttraumatic growth (PTG), positive psychological changes resulting from highly stressful events; however, the longitudinal course of PTG is poorly understood. PURPOSE: The purpose of the present study was to determine trajectories of PTG in breast cancer survivors and associated characteristics. METHODS: Women (N = 653) participating in a longitudinal observational study completed questionnaires within 8 months of breast cancer diagnosis and 6, 12, and 18 months later. Group-based modeling identified PTG trajectories. Chi-square tests and ANOVA detected group differences in demographic, medical, and psychosocial variables. RESULTS: Six trajectory groups emerged. Three were stable at different levels of PTG, two increased modestly, and one increased substantially over time. Trajectory groups differed by age, race, receipt of chemotherapy, illness intrusiveness, depressive symptoms, active-adaptive coping, and social support. CONCLUSIONS: This first examination of PTG trajectories in US cancer survivors elucidates heterogeneity in longitudinal patterns of PTG. Future research should determine whether other samples exhibit similar trajectories and whether various PTG trajectories predict mental and physical health outcomes.
