The Posttraumatic Growth Inventory: an examination of the factor structure and invariance among breast cancer survivors

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.

Posttraumatic stress symptoms, posttraumatic growth, and personality factors: A network analysis

BACKGROUND

After experiencing a traumatic event, two possible outcomes are experiencing positive changes, such as posttraumatic growth (PTG), and/or experiencing distress in the form of posttraumatic stress symptoms (PTSS). These constructs are not mutually exclusive; those who experience PTSS may concurrently or at a later date likewise undergo PTG. Pretrauma factors, such as personality as measured by the Big Five Inventory (BFI), can interact with both PTSS and PTG.

METHODS

The present study utilized Network theory to examine the interactions between PTSS, PTG, and personality in 1310 participants. Three networks were computed (PTSS, PTSS/BFI, PTSS/PTG/BFI).

RESULTS

Within the PTSS network, strong negative emotions emerged as the strongest influence on the network. Again, in the PTSS and BFI network, strong negative emotions exerted the strongest overall influence in addition to bridging the PTSS and personality domains. In the network with all variables of interest, the PTG domain of new possibilities was the strongest overall influence on the network. Specific relationships between constructs were identified.

LIMITATIONS

Limitations of this study include the cross-sectional design and utilization of a sub-threshold PTSD, non-treatment seeking sample.

CONCLUSIONS

Overall, nuanced relationships between variables of interest were identified, informing personalized treatment and furthers our understanding of both positive and negative responses to trauma. As the primary influence across two networks, the experience of strong negative emotions appears to be central to the subjective experience of PTSD. This may indicate a need to modify present treatments for PTSD, which conceptualize PTSD as a primarily fear-based disorder.

Benefits of nature-based walking for breast cancer survivors

INTRODUCTION

Physical activity (PA) promotes significant physical and psychosocial benefits for breast cancer survivors. While evidence exists regarding recommendations for the frequency, duration and intensity of exercise that optimise PA benefits for cancer survivors, the role of the environment in achieving optimal outcomes has yet to be determined. This paper presents a protocol for a clinical trial to evaluate the feasibility of a 3-month nature-based walking programme for breast cancer survivors. Secondary outcomes assessed include the impact of the intervention on fitness, quality of life outcomes, and biomarkers of ageing and inflammation.

METHODS AND ANALYSIS

The trial is a 12-week single-arm pilot study. Twenty female breast cancer survivors will engage in a supervised moderate intensity walking intervention in small groups in a nature reserve for 50 minutes three times per week. Data will be collected at baseline and end of study, and include assessment of inflammatory cytokines and anti-inflammatory myokines (TNF-α, IL-1ß, IL-6, CRP, TGF-ß, IL-10, IL-13), as well as ageing (DNA methylation, ageing genes) biomarkers; surveys (Patient-Reported Outcomes Measurement Information System-29, Functional Assessment of Cancer Therapy-General, Post-Traumatic Growth Inventory); and fitness assessments (6 min Walk Test, Grip-Strength, One Repetition-Maximum Leg Press). Participants will also complete weekly surveys assessing social support and participate in an exit interview. This is an important first step for future research on the influence of exercise environment on cancer survivor PA outcomes.

ETHICS AND DISSEMINATION

This study was approved by the Cedars Sinai Medical Center Institutional Review Board (IIT2020-20). Findings will be disseminated through academic manuscripts, conferences, and community presentations.

"Psychometric properties of the Arabic version of the post-traumatic growth inventory with university students in Jordan

Post-traumatic Growth plays a key role to cope with traumatic incidents. The scale for Post-Traumatic Growth Inventory (PTGI) has been used by several researchers in different languages. This study aims to evaluate the Arabic-translated version of the PTGI scale by focusing on its validity in different languages and contexts. This study introduces an Arabic version of the PTGI-M normed with 417 undergraduate students at a large university in Jordan. The internal consistency (Cronbach's alpha) and test-retest reliability of the instrument were 0.97 and 0.82, respectively. Bivariate correlation was used to approximate the concurrent validity (CV). Significant correlations were found between the PTGI-M and the beck depression inventory (BDI), perceived stress scale (PSS), Taylor's manifest anxiety (TMAS), satisfaction with life (SWL), and the Rosenberg self-esteem scale (RSES). Confirmatory factor analysis (CFA) to assess the convergent and discriminant validity of the translated scale. Convergent and discriminant validity was established for the Arabic version of the PTGI-M by conducting a confirmatory factor analysis (CFA). In conclusion, this study proposes that future investigations should consider analysing the total PTGI-M subtotal scores to comprehend the complexity of the post-traumatic growth experience.

Factor structure of the Parenting Stress Index-Short Form used in the Japan Environment and Children's Study

The Parenting Stress Index-Short Form (PSI-SF) has been widely employed to assess parenting stress in a number of research and clinical trials. To date, no parenting stress studies in Japan have examined the factor structure, validity, and reliability of the PSI-SF. Therefore, this study aimed to evaluate the psychometric properties of this 19-item version as administered in a national cohort study, the Japan Environment and Children's Study, to two sample groups of mothers, those with a 1.5-year-old child and those with a 2.5-year-old child (n = 79,282 and 75,831, respectively). We performed exploratory factor analysis to re-examine the appropriate factor structure, confirmatory factor analysis to evaluate goodness of fit, and calculated Cronbach's α and Pearson's r coefficients to evaluate internal consistency and reproducibility over time, respectively. The results highlighted that a three-factor structure fit the instrument better than a two-factor structure, yielding better scores for the model fit indices and the α and r coefficients. In addition, the third factor identified in this study was strongly associated with having a relationship with and help from the husband. The findings suggest the importance of using a parenting stress scale with various factors to evaluate mothers' parenting stress.

Posttraumatic growth inventory: challenges with its validation among French cancer patients

Background

The Posttraumatic growth inventory (PTGI) aims to assess the positive psychological changes that individuals can perceive after a traumatic life event such as a cancer diagnosis. Several French translations of the PTGI have been proposed, but comprehensive data on their psychometric properties are lacking. This study aimed to provide a more complete assessment of the psychometric properties of one of the most used PTGI translations in early-stage breast cancer and melanoma patients.

Methods

A sample of 379 patients completed the PTGI two years after their cancer diagnosis. A confirmatory analysis was first performed to determine whether the initial five-factor structure of the PTGI was adequate for this French version. As issues were identified in the translation and in the questionnaire structure, we performed an exploratory analysis to determine the most suitable structure for this questionnaire. Validity and reliability of the evidenced structured were then assessed.

Results

The exploratory analysis evidenced a four-factor structure close to the initial structure: four of the five initial domains were recovered, and items from the unrecovered domain were split into the other domains. This new structure showed good internal consistency and acceptable validity.

Conclusions

This study highlights that the process of translation and cross-cultural validation of questionnaires is crucial to obtain valid and reliable psychometric instruments. We advise French psycho-oncology researchers and psychotherapists to (i) use the revised translation of Lelorain et al. (2010) proposed in this manuscript and (ii) use the four scores newly evidenced with a grouping of two response categories.

Investigating PTG in Cancer Patients: The Role of Time Dimension in the Experience of Personal Growth

This study explored the experience of growth related to being a cancer patient by implementing a thematic analysis. An online questionnaire was completed by 69 patients narrating their growth experience related to cancer. Collected narratives were analyzed by running a deductive thematic analysis, starting from the five domains of the Post-Traumatic Growth Inventory (PTGI) and searching for the presence or absence of topics. Descriptive statistics and correlational analysis were performed. The five factors of the PTGI were identified in the narratives. The thematic analysis we performed defined a further theme that we labeled the “time dimension”, which saturated 37.7% of the entire sample. The presences of four sub-themes related to the “time dimension” were also found: “tracing a new temporal rhythm”, “the value of deserved time”, “facing the caducity of life” and “a view on the future”. Each sub-theme significantly correlated with the theme of the “time dimension”. This emergent theme does not correlate in our results with other domains of personal growth in cancer previously described in the scientific literature, emerging as an independent variable not significantly associated with other domains of post-traumatic growth. Our results suggest further investigation in the role of the time dimension in the practical and emotional experience of growth with regard to cancer.

Supporting the Return to Work of Breast Cancer Survivors: From a Theoretical to a Clinical Perspective

Promoting the return to work of breast cancer survivors is of major interest to patients, healthcare and occupational health professionals, companies, governments, and researchers worldwide. We previously conducted a French consensus study resulting in a model describing the multifactorial process of the return to work of breast cancer survivors (the REWORK-BC model). Other work has identified the transtheoretical model as a relevant theoretical framework for interventions to promote the return to work of cancer survivors. In this opinion paper, we provide a theoretically-based clinical framework describing how to support breast cancer survivors at each stage of the return-to-work process. This clinical framework considers several essential aspects of supportive care for breast cancer survivors returning to work, such as: (i) helping the patient actively self-manage, by considering her to be the main decision-maker; (ii) respecting and adapting to the patient’s choice of professional project; (iii) respecting the temporality of the patient’s choices; (iv) proposing tailored interventions; (v) implementing simple tools to promote the return to work, shared representation between the patient and a multidisciplinary team, and improvement of working conditions and the knowledge of health and occupational professionals, and managers or employers; and (vi) maintaining certain flexibility aimed at proposing, but never imposing, changes in practices. This clinical framework, specific to breast cancer survivors, could be extrapolated to other tumor types, offering a practical guide for healthcare and occupational health professionals to better understand the return-to-work process of cancer survivors. This clinical framework aims to be a usable tool for any hospital or cancer care center wishing to implement a patient-centered intervention that promotes returning to work, regardless of the country.

A longitudinal cohort study on benefit finding evolution in Chinese women breast cancer survivals

Even though the prevalence of benefit finding (BF) has been empirically shown to exist among breast cancer (BC) survivals, how does benefit finding evolve over time remains inadequately investigated. The objective of this cohort study is to examine how BF evolves over time among Chinese breast cancer survivals and determine the demographic, medical and psychosocial factors that can sustain BF increase over time. Participants were 486 women with different stages of breast cancer (stages I, II and III) followed from completion of primary treatment. Analysis were performed on the data collected during 2014–2019. During the assessment, each participant completed self-report questionnaires of characteristics and benefit finding at six time points with the interval of 6 months since BC diagnosis. The relationships between demographic, medical and psychosocial characteristics and benefit finding evolution over time were examined using mixed models. Participants reported mixed results on the evolving patterns of benefit finding: 28% reported an upward trend in BF scoring over time, 49% instead reported an downward trend, and the remaining 23% reported no obvious change. Our study has shown that some well-known covariates of benefit finding, e.g. education, income, and social support, are not associated with BF trends. In comparison, levels of spirituality and disease coping at diagnosis can more reliably predict BF evolution over time. Identifying the sustaining factors of benefit finding in the experience of breast cancer is the key to design effective psycho clinical solutions for patients’ long-term post-traumatic growth. As time goes by, breast cancer patients may experience less benefit finding. Our results strongly indicate that benefit finding can be sustained and increased by encouraging attempts at meaning-making and active disease coping during breast cancer treatment. To the best of our knowledge, this study is among the first to examine the evolution trends of benefit finding over time on breast cancer survivals and determine their psychosocial predictors in developing countries.

Crescimento Pós-Traumático no Câncer de Mama: Centralidade de Evento e Coping

Resumo Crescimento pós-traumático (CPT) refere-se à mudança positiva em algum aspecto da experiência humana como resultado do enfrentamento de adversidades. Investigou-se a relação entre CPT, estilos de enfrentamento e centralidade de evento. Participaram do estudo 65 mulheres que concluíram os tratamentos recomendados para o câncer de mama. Tratou-se de uma pesquisa quantitativa cujos instrumentos foram respondidos on-line. Identificou-se correlações altas entre CPT e centralidade de evento e moderadas entre CPT e os estilos de enfrentamento: estratégia focada no problema, busca de suporte social e práticas religiosas. A centralidade de evento e as estratégias focadas no problema mostraram-se melhores preditoras de CPT. Os resultados sugerem que quanto maior a adversidade percebida, maior a possibilidade de crescimento, sendo as estratégias de enfrentamento focadas no problema um componente importante para a sua ocorrência. Este estudo apontou a possibilidade de crescimento pessoal relacionado ao enfrentamento do CA de mama e indicou estratégias relevantes para desenvolvê-lo.

Prevalence of benefit finding and posttraumatic growth in long-term cancer survivors: results from a multi-regional population-based survey in Germany

Background

Cancer studies reported mixed results on benefit finding (BF) and posttraumatic growth (PTG) prevalence and few were focused on long-term survivors.

Methods

BF and PTG were assessed in a multi-regional population-based study in Germany with 6952 breast, colorectal and prostate cancer survivors, using the Benefit Finding Scale and Posttraumatic Growth Inventory. We calculated the age-adjusted prevalence, stratified by demographical and clinical characteristics.

Results

Overall, 66.0% of cancer survivors indicated moderate-to-high BF, and 20.5% moderate-to-high PTG. Age-adjusted prevalence of BF and PTG differed according to cancer type (breast > colorectal > prostate) and sex (female > male). BF and PTG prevalence were higher in younger than in older respondents; the age-adjusted prevalence was higher in respondents who survived more years after diagnosis. The strength and direction of associations of age-adjusted prevalence with cancer stage, disease recurrence, and time since diagnosis varied according to cancer type and sex.

Conclusions

A substantial proportion of long-term cancer survivors reported moderate-to-high BF and PTG. However, the prevalence was lower in older and male cancer survivors, and during the earlier years after cancer diagnosis. Further longitudinal studies on PTG and BF in cancer survivors are warranted to address heterogeneity in survivors’ experience after cancer diagnosis.

Psychological predictors of posttraumatic growth among adult survivors of Wenchuan earthquake in China

The current research investigates the applicability of the posttraumatic growth inventory and psychological predictors of posttraumatic growth among adult survivors of the Wenchuan earthquake in China. The results indicated that although the survivors reported a high degree of posttraumatic stress symptoms, they also experienced a moderate to high level of posttraumatic growth two years after the earthquake. The simplified Chinese version of the Posttraumatic Growth Inventory had good reliability in the current study. Confirmatory factor analysis of the simplified Chinese version of the Posttraumatic Growth Inventory verified that the original five-factor model fit the data better than the four-factor model documented by Ho et al. (2004, 2011) among Chinese cancer patients. The current study also demonstrates that positive changes in outlook, positive affect, and perceived social support are significant predictors of posttraumatic growth among adult survivors of the Wenchuan earthquake. Directions for future research on posttraumatic growth among survivors of natural disasters and implications for developing psychological interventions to help people recover from traumatic events are discussed.

Measuring positive psychosocial sequelae in patients with advanced cancer

OBJECTIVE

Posttraumatic growth and benefit finding describe the potential for positive changes resulting from traumatic experiences, including cancer. In oncology, these constructs are increasingly examined concurrently using the Posttraumatic Growth Inventory (PTGI) and the Benefit Finding Scale (BFS). However, distinctions between these constructs and their corresponding scales are not altogether clear, and the burden of administering 2 lengthy questionnaires is evident, particularly for patients at end-of-life.

METHOD

Baseline data from 209 participants enrolled in a randomized controlled trial evaluating the efficacy of a psychosocial intervention were analyzed. We assessed the structure and covariance of all PTGI and BFS items using item response theory to determine the extent to which these measures overlap and the potential value of their concurrent administration in patients with advanced cancer.

RESULTS

Despite conceptual differences in posttraumatic growth and benefit finding, results indicated that these measures address the same underlying construct. We subsequently analyzed 3 abbreviated scales (7, 11, and 16 items) that combine items from both scales to identify an optimal briefer combined scale. Results supported all 3 versions, with the 7- and 16-item measures appearing to have the best balance of content and concurrent validity and the 11-item version optimizing information gained with brevity.

CONCLUSIONS

These findings indicate that concurrent administration of the PTGI and BFS may be unnecessary given the high degree of overlap between these 2 measures and that a brief subset of items may adequately evaluate positive change among patients with advanced cancer while reducing participant burden.

The factor structure of the posttraumatic growth inventory in cancer patients in Turkey

Posttraumatic growth is a positive psychological change that occurs as a result of tackling vital crises. Although cancer is perceived as a fatal disease, the individual's struggle with many negative conditions during diagnosis and treatment can provide positive change and development. The aim of this study was to examine the factor structure of the posttraumatic growth inventory (PTGI) in Turkish cancer patients. This study included 265 cancer patients receiving treatment at the chemotherapy unit of two university hospitals located in northern Turkey. Percentages, frequencies, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to analyse the data, and Cronbach's α measured internal consistency. EFA yielded a five-factor structure: Spiritual and existential change, change in perception of life and selfness, relating to others, personal strength and new possibilities. Fit indices for CFA were root mean square error of approximation (RMSEA), 0.06; non-normed fit index (NNFI), 0.92; comparative fit index (CFI), 0.90; root mean residuals (RMR), 0.06; and goodness-of-fit index (GFI), 0.90. The overall Cronbach's α of the scale was 0.93. PTGI was determined as a reliable and valid tool for Turkish cancer patients. PTGI, which has a determined validity and reliability rate, can be used by healthcare professionals working with oncology patients to evaluate the positive psychological growth and changes in cancer patients and determine their adoption rate.

Posttraumatic growth following cancer: The influence of emotional intelligence, management of intrusive rumination, and goal disengagement as mediated by deliberate rumination

Numerous researchers have demonstrated that deliberate rumination serves as the foremost precursor to posttraumatic growth (PTG). However, understanding the factors responsible for facilitating deliberate rumination remains limited. This study examined three factors proposed by the functional-descriptive model of PTG as facilitators of deliberate rumination-emotional intelligence, management of intrusive rumination, and goal disengagement-among the cancer survivor population. Cancer survivors (N = 221) were surveyed using mail-based methodology within two months and five years of completion of all cancer treatment. Relationships among PTG, deliberate rumination, management of intrusive rumination, emotional intelligence, and goal disengagement were analyzed using path analysis. Results suggested a positive link between emotional intelligence and PTG and deliberate rumination and PTG, and a negative link between management of intrusive rumination and deliberate rumination and goal disengagement and deliberate rumination. Interventions designed to enhance deliberate rumination and emotional intelligence are warranted, and the functional-descriptive model is in need of amendment if it is to accurately capture the experience of cancer survivors.

Assessing the Latent Structure of Posttraumatic Growth and Its Relationship With Cognitive Processing of Trauma Among Filipino Women Victims of Intimate Partner Abuse

The study intends to find out which model best represents posttraumatic growth's (PTG) latent factor structure in a sample of Asian, particularly Filipino, women victims of intimate partner abuse (IPA) using Posttraumatic Growth Inventory (PTGI). In addition, it also aims to find out the differential relationships of the components of the best-fitting PTG model with cognitive processing strategies. Confirmatory factor analyses were conducted with the one-factor, three-factor, and five-factor models of PTG in a sample of 217 Filipino women who have history of IPA within the last 6 months of a previous or current relationship. Results revealed that the five-factor model comprised of appreciation of life, new possibilities, personal strength, spiritual change, and relating to others best fits the sample. Furthermore, all the components of the five-factor model were found to be positively correlated with cognitive processing of trauma strategies, including positive cognitive restructuring, denial, downward comparison, regret, and resolution/acceptance, albeit in varying degrees. These findings confirmed the robustness of the five-factor model of PTG compared with other models in a sample of women victims of IPA. In addition, the findings demonstrated the relationship of PTG with cognitive processing of trauma. These findings would be useful in developing cognitive interventions for women who experienced IPA.

Examining posttraumatic growth and mental health difficulties in the aftermath of Hurricane Sandy

OBJECTIVE

Hurricane Sandy continues to affect the mental health of New York residents. This study examined associations between Posttraumatic Growth (PTG) and mental health difficulties (MHD) including symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD).

METHOD

Participants (N = 1,356) recruited from the New York metropolitan area completed questionnaires regarding their PTG, demographics, MHD, and hurricane experiences. A weighted least squares regression assessed the association between MHD and PTG. A post hoc analysis determined whether anxiety or depression moderated the effect of PTSD on PTG.

RESULTS

All MHD were crudely associated with greater PTG. After adjustment, an increased PTSD score was significantly associated with a 0.20 unit increase in PTG (t = 6.05, p < .001); this did not hold for depression or anxiety symptoms. Higher PTG was associated with being non-White (B = 5.90, t = 6.49, p < .001), Hispanic (B = 3.38, t = 2.89, p = .004), a smoker (B = 3.18, t = 3.28, p = .001), and greater Hurricane Sandy exposure (t = 7.11, p < .001). The positive association between PTSD symptoms and PTG was weaker among participants with probable depression.

CONCLUSION

Results suggest that participants with higher PTSD symptoms were more likely to grow from the impact of the storm, indicating resilience. Highly exposed participants were more likely to experience PTG. A decrease in PTG was found among those with both PTSD and depression symptoms. The development and implementation of interventions fostering PTG could be beneficial in clinical disaster response work. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Life after breast cancer: moving on, sitting down or standing still? A prospective study of Canadian breast cancer survivors

INTRODUCTION

Breast cancer (BC) is associated with serious physical and psychological health sequelae that affect quality and quantity of life. Physical activity (PA) and sedentary behaviour can prevent or diminish these sequelae; yet, little is known about how these lifestyle behaviours change after cancer treatment and if these changes affect post-treatment health. The first aim of this study is to describe natural trends in lifestyle behaviours (ie, PA, sedentary behaviour) in women treated for BC. The second aim is to examine the longitudinal associations between lifestyle behaviour changes and (1) physical health (eg, acute symptoms, chronic conditions, body composition, patient-reported fatigue, pain and functioning), (2) psychological health and illness (eg, depression, stress, affect, post-traumatic growth, cancer worry, mood, body image) and (3) biological functioning (eg, cortisol and C-reactive protein). The third aim is to examine modifiable self-regulation (ie, goal adjustment strategies) and motivation constructs (ie, self-determined regulations) that predict trends in lifestyle behaviours.

METHOD AND ANALYSIS

This is a prospective longitudinal study of 201 women treated for BC. Data (eg, surveys, accelerometers, saliva, blood) are collected every 3 months during the first year after women complete systemic treatment for a first diagnosis of BC, and once every year for 4 years thereafter. Data analyses assess trends and changes in PA and sedentary lifestyle behaviours, examine associations between these trends and changes in health outcomes and identify modifiable predictors of PA and sedentary lifestyle behaviours using multilevel modelling.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the University of Toronto (REB# 28180) and has been funded by the Canadian Institutes of Health Research (#186128). Study findings will be disseminated through peer-reviewed publications, academic conferences, local community-based presentations such as the Canadian Cancer Society and similar organisations.

Vicarious trauma and vicarious posttraumatic growth among substance abuse treatment providers

BACKGROUND

Practitioners working with clients who have experienced trauma are vulnerable to experiencing both vicarious trauma and vicarious posttraumatic growth (PTG). A survey was conducted in which treatment providers who work with adults seeking help for substance abuse were asked about their experience of vicarious trauma and vicarious PTG. It was hypothesized that vicarious trauma and vicarious PTG would be positively associated with each other, that personal history of trauma and years of working with clients who had experienced trauma would be positively associated with vicarious trauma, and that in addition to those variables, personal counseling, training, and supervision would be associated with vicarious PTG.

METHODS

Surveys were sent to the directors of 15 social service agencies in one county in central California. Surveys included questions about the respondent's history of substance use and trauma and experience with clients who had experienced trauma. In addition, the survey contained 3 scales: the Trauma History Screen, the Posttraumatic Growth Inventory, and the Impact of Event Scale-Revised.

RESULTS

Survey data were obtained from 51 counselors. There was a significant positive association between vicarious trauma and vicarious PTG, and both were significantly associated with respondents' history of trauma. Providers who were in recovery were more likely than others to report a history of trauma and to report higher levels of vicarious trauma and vicarious PTG.

CONCLUSION

Counselors working with clients in substance abuse treatment may experience vicarious trauma and vicarious PTG. Implications for preparing counselors to work with this population are discussed.

Psychological and clinical correlates of posttraumatic growth in cancer: A systematic and critical review

OBJECTIVE

The objective of this study is to describe major findings on posttraumatic growth (PTG) in cancer, by analyzing its various definitions, assessment tools, and examining its main psychological and clinical correlates.

METHODS

A search in relevant databases (PsycINFO, Pubmed, ProQuest, Scopus, and Web of Science) was performed using descriptors related to the positive reactions in cancer. Articles were screened by title, abstract, and full text.

RESULTS

Seventy-two met the inclusion criteria. Most articles (46%) focused on breast cancer, used the PTG inventory (76%), and had a cross-sectional design (68%). The PTG resulted inversely associated with depressive and anxious symptoms and directly related to hope, optimism, spirituality, and meaning. Illness-related variables have been poorly investigated compared to psychological ones. Articles found no relationship between cancer site, cancer surgery, cancer recurrence, and PTG. Some correlations emerged with the elapsed time since diagnosis, type of oncological treatment received, and cancer stage. Only few studies differentiated illness-related-life-threatening stressors from other forms of trauma, and the potentially different mechanisms connected with PTG outcome in cancer patients.

CONCLUSIONS

The evaluation of PTG in cancer patients is worthy, because it may promote a better adaption to the illness. However, many investigations do not explicitly refer to the medical nature of the trauma, and they may have not completely captured the full spectrum of positive reactions in cancer patients. Future research should better investigate issues such as health attitudes; the risks of future recurrences; and the type, quality, and efficacy of medical treatments received and their influence on PTG in cancer patients.

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.

A psychometric evaluation of hierarchical and oblique versions of five variants of the Posttraumatic Growth Inventory

The Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996) is the most commonly used measure of posttraumatic growth. Although the original five factor structure has extensive psychometric support, evidence exists for alternate PTGI models. The current study assessed the validity of oblique and hierarchical factor structures of five PTGI models. Confirmatory factor analyses were performed among a heterogeneous community sample with a diverse trauma history. The oblique models provided a better fit to the data compared with their respective hierarchical models. Three oblique variants provided good fit to the data on two fit indices and all five oblique variants met the recommended criteria for at least one fit index. The 10-item model demonstrated the lowest Expected Cross-Validation Index (ECVI) values and is a brief and useful measure when examining PTGI total scores; however, current results suggest that consideration of the specific subscales may be more meaningful than total scores. Researchers and clinicians interested in subscale scores should consider using the 18- or 21-item variants due to a higher number of items per factor and, therefore, greater factor stability. Future directions in refining and measuring posttraumatic growth are discussed.

Moderating effects of perceived growth on the association between fear of cancer recurrence and health-related quality of life among adolescent and young adult cancer survivors

We examined whether (1) fear of cancer recurrence was related to lower health-related quality of life and (2) perceived growth moderated the link between fear of recurrence and health-related quality of life. About 292 adolescent and young adult cancer survivors (diagnosed with cancer at ages 15-34) completed a cross-sectional survey. Fear of recurrence was related to poorer physical and mental health-related quality of life. The negative association between fear of recurrence and mental health-related quality of life was moderated by perceived growth. Fostering perceived growth may mitigate the adverse associations of fear of recurrence and health-related quality of life.

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.

Resilience and psychosocial adjustment in digestive system cancer

The study aims to investigate the contributions of resilience, affective reactions and post traumatic growth (PTG) to psychosocial adjustment and behavioral changes among digestive system cancer patients in Israel. A sample of 200 participants, 57.5 % men (from the 46 to 70-year age range), 1-4 years following diagnosis, completed an inventory assessing demographic and medical information, resilience, current positive affect (PA) and negative affect (NA), PTG, psychosocial adjustment and retrospective report of behavioral changes following cancer treatment. Resilience, PA and NA, and PTG were related to adjustment and/or reported behavioral changes, and PA, NA and PTG mediated some of the effects of resilience on adjustment and/or reported behavioral changes. The data underline the importance of resilience, affect, and PTG in the adjustment of digestive system cancer patients. Future studies are needed to better understand the associations of resilience with psychosocial adjustment and behavioral changes. This knowledge may help improve cancer survivors' adjustment.

The need for friendships and information: Dimensions of social support and posttraumatic growth among women with breast cancer

Objective:

Employing a cross-sectional design, the current study examined the relationships between various agents and types of support and posttraumatic growth (PTG) among women with breast cancer.

Method:

Eighty married women who were coping with breast cancer completed social support and PTG questionnaires.

Results:

All agents of social support (family, friends, belief-based), excluding spousal support, and all types of social support were found to be related to the various PTG dimensions and its total score. Regression analyses revealed that, among the agents of support, only support provided from friends and belief-based support uniquely contribute to prediction of total PTG score. While examining the contribution of various types of support, only cognitive support had a unique contribution to prediction of total PTG score.

Significance of results:

Various agents and types of support play different roles in the PTG process following breast cancer. Accordingly, friends as an agent of support and information as a type of support seem to be most important in enhancing PTG among women with breast cancer.

Posttraumatic Growth Outcomes and Their Correlates Among Young Adult Survivors of Childhood Cancer

OBJECTIVE

This study aims to identify and examine posttraumatic growth (PTG) experiences, and their correlates, among young adult survivors of childhood cancer.

METHODS

602 long-term childhood cancer survivors between the ages of 18 and 39 participated. Their demographic (age, gender, race/ethnicity, education, relationship status, employment, and income), cancer-related (diagnosis, current health problem, age at diagnosis, and years since diagnosis), and psychosocial (social support and optimism) PTG correlates were examined using descriptive, correlational, and regression analyses.

RESULTS

PTG was significantly greater for females and nonwhite survivors, and for those diagnosed at older ages. Survivors diagnosed with solid/soft tissue tumors reported lower PTG. Optimism and social support were positively associated with PTG.

CONCLUSION

Study findings highlight potential intervention opportunities for increasing PTG by facilitating discussion around growth experiences within an optimistic framework among a supportive network of family members and peers.

Posttraumatic growth and demoralization after cancer: The effects of patients' meaning-making

Objective:

It is common for patients to experience positive and negative psychological changes (e.g., posttraumatic growth or demoralization) after being diagnosed with cancer. Although demoralization and posttraumatic growth are both related to meaning-making, little attention has been paid to the associations among these concepts. The current study investigated the relationship between demoralization, posttraumatic growth, and meaning-making (focusing on sense-making and benefit-finding during the experience of illness) in cancer patients.

Method:

Some 200 cancer patients (with lung cancer, lymphoma, or leukemia) at the MacKay Memorial Hospital in New Taipei completed the Demoralization Scale–Mandarin Version (DS–MV), the Chinese Posttraumatic Growth Inventory (CPTGI), and a self-designed questionnaire for assessing sense-making and benefit-finding.

Results:

Demoralization was negatively correlated with posttraumatic growth, sense-making, benefit-finding, and time-since-diagnosis. Multiple regression analysis showed that meaning-making had different effects on demoralization and posttraumatic growth. The interactions of sense-making with either benefit-finding or time-since-diagnosis significantly predicted demoralization. Individuals with relatively higher sense-making and benefit-finding or shorter time-since-diagnosis experienced less demoralization.

Significance of Results:

The suffering of cancer may turn on the psychological process of demoralization, posttraumatic growth, and meaning-making in patients. Cancer patients who evidenced higher posttraumatic growth experienced less demoralization. Trying to identify positive changes in the experience of cancer may be a powerful way to increase posttraumatic growth. As time goes by, patients experienced less demoralization. Facilitating sense-making can have similar effects. Cancer patients with less benefit-finding experience higher demoralization, but sense-making buffers this effect.

Evaluation of the Quality of Life in Adult Cancer Survivors (QLACS) scale for early post-treatment breast cancer survivors

PURPOSE

The end of primary treatment for cancer patients is increasingly recognized as an important time of adjustment that may impact quality of life (QoL). A psychometrically sound QoL instrument that assesses the mix of acute and longer-term concerns present during this unique time has not yet been identified. This article evaluates the Quality of Life in Adult Cancer Survivors (QLACS) scale, originally developed for long-term (>5 years) cancer survivors, as an appropriate QoL measure for this transition period.

METHODS

Psychometric properties of the QLACS were evaluated in a sample of post-treatment breast cancer survivors 18-24 months post-diagnosis. This observational study consisted of women (n = 552) aged 25 years and older (mean = 55.4 years) who were diagnosed with stage I, II, or III breast cancer. The 47 items of the QLACS comprise 12 domains: seven domains are generic, and five are cancer specific.

RESULTS

The QLACS demonstrated adequate internal consistency (Cronbach's alpha for the 12 domains ranged from 0.79 to 0.91) and good convergent and divergent validity (assessed by comparison with the Functional Assessment of Cancer Therapy and other measures).

CONCLUSIONS

The QLACS appears to be consistent with other widely accepted measures in capturing QoL, while also allowing for more inclusive measurement of specific issues relevant to post-treatment cancer survivors. These data, in addition to previous data supporting use of the QLACS across different cancer sites, suggest that the QLACS is a promising comprehensive QoL measure appropriate for breast cancer survivors transitioning off active treatment.

"A gift wrapped in barbed wire" positive and negative life changes after being diagnosed with inflammatory bowel disease

PURPOSE

A growing interest in posttraumatic growth among individuals who have experienced a traumatic event has given rise to measures such as the Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996). However, such measures may not fully represent all dimensions of change among individuals diagnosed with a chronic disease and fail to highlight the negative changes that may also occur. This study explores the positive and negative changes patients with inflammatory bowel disease (IBD) have experienced since diagnosis.

METHODS

Three hundred and seventy-eight IBD patients provided answers to the qualitative question "Could you please describe the (positive/negative) effect(s) IBD has had on your life?" A grounded theory approach using NVivo was performed on participants' responses.

RESULTS

Nearly 73 % of participants reported their disease positively affected their life in some way, and five themes related to positive changes emerged from the analysis: Interpersonal Relations, Personal Growth, Valuing Life, New Life Paths, and Spiritual Growth. However, almost 80 % of participants also reported their disease negatively affected their lives, with three themes emerging from the analysis: Freedom Restrictions, Psychological Side Effects, and Social Isolation.

CONCLUSIONS

Our results support previous findings but also reveal that some dimensions related to the positive changes following adversity are not adequately assessed by the PTGI (e.g., appraising existing friendships, openness to try different forms of treatment or therapies, and psychological preparedness). The implications of these findings for future measurement and research of posttraumatic growth with IBD patients are discussed.

The factorial and discriminant validity of the German version of the Post-traumatic Growth Inventory in stroke patients

Post-traumatic growth (PTG) is the experience of positive changes that can follow a traumatic event. The current study examined the factorial as well as the discriminant validity of the German version of the Post-traumatic Growth Inventory (PTGI-G) in stroke patients. A total of 188 adult stroke patients (63.3% male; median age 69 years) completed the PTGI-G and the German version of the Hospital Anxiety and Depression Scale (HADS-D) at the end of their inpatient rehabilitation. Confirmatory factor analyses indicate an acceptable model fit of both the original five-factor solution as well as a second-order factor model of the PTGI-G (CFI > .95; RMSEA < .01). Small and non-significant correlations between the PTGI-G subscales and the depression scale of the HADS-D support the discriminant validity of the PTGI-G. The PTGI-G appears to be a valid tool in the context of stroke research.

Psychometric Properties of the Portuguese Version of the Posttraumatic Growth Inventory Short Form Among Divorced Adults

The aim of this study was to develop and validate a Portuguese version of the Short Form of the Posttraumatic Growth Inventory (PTGI-SF). Using an online convenience sample of Portuguese divorced adults (N = 482), we confirmed the oblique five-factor structure of the PTGI-SF by confirmatory factor analysis. The results demonstrated the measurement invariance across divorce initiator status groups. Total score and factors of PTGI-SF showed good internal consistency, with the exception of the New Possibilities factor, which revealed an acceptable reliability. The Portuguese PTGI-SF showed a satisfactory convergent validity. In terms of discriminant validity, posttraumatic growth assessed by the Portuguese PTGI-SF was a distinct factor from posttraumatic psychological adjustment. These preliminary findings suggest the cultural adaptation and also psychometric properties of the present Portuguese PTGI-SF to measure posttraumatic growth after personal crisis.

A bifactor model of the Posttraumatic Growth Inventory

Purpose: The Posttraumatic Growth Inventory (PTGI) is a self-administered measurement instrument designed to provide information concerning positive psychological changes after a traumatic life event. The aim of the present study was to examine the psychometric properties of the PTGI in a Hungarian sample. By examining a bifactor model of the instrument, we also wanted to contribute to the establishment of an evidence-based practice concerning the use of different score types (total score versus subscale scores). Methods: Altogether, 691 Hungarian respondents (82.2% female; M_age = 33.0 ± 13.4 years), who experienced some kind of trauma or loss, participated in this study. Results: A series of confirmatory factor analyses revealed that among the tested first- and second-order models, a bifactor model provided the best-fit to our data (χ²/df = 4.32, Comparative Fit Index = .91, root mean square error of approximation = .07, standardized root mean square residual = .04). Further, the Hungarian version of the PTGI showed high internal consistency (Cronbach's alpha = .93, omega total = .95, omega hierarchical = .87) and test–retest reliability (r = .90; p < .01) coefficients. However, omega hierarchical coefficients (.14–.40) and explained variance values (.05–.10) for the subscales were low. Conclusions: The present study provided empirical support for the psychometric adequacy of the Hungarian adaptation of the PTGI and suggests that only the total and not the subscale scores of the inventory should be used.

Existence of benefit finding and posttraumatic growth in people treated for head and neck cancer: a systematic review

Background. The impact of head and neck cancer (HNC) in long-term survivors differs widely among individuals, and a significant number of them suffer from the negative effects of disease, whereas others report significant positive effect. This systematic review investigated the evidence the implications of treatment for HNC and subsequent development of Benefit Finding (BF) or Posttraumatic Growth (PTG). Purpose. To understand how differing medical, psychological and social characteristics of HNC may lead to BF/PTG and subsequently inform post-treatment interventions to encourage positive outcomes. Method. In February 2012, five databases including Pubmed, and Psych Info, were searched, for peer-reviewed English-language publications. Search strings included key words pertaining to HNC, BF, and PTG. One thousand three hundred and sixty three publications were identified, reviewed, and reduced following Cochrane guidelines and inclusion/exclusion criteria specified by a group of maxillofacial consultants and psychologists. Publications were then quality assessed using the CASP Cohort Critical Appraisal tool. Findings. Five manuscripts met the search and selection criteria, and were sourced for review. All studies were identified as being level IIb evidence which is a medium level of quality. The majority of studies investigated benefit finding (80%) and were split between recruiting participant via cancer clinics and postal survey. They focused on the medical, psychological and social characteristics of the patient following completion of treatment for HNC. Conclusion. Demographic factors across the papers showed similar patterns of relationships across BF and PTG; that higher education/qualification and cohabitation/marriage are associated with increased BF/PTG. Similarly, overlap with disease characteristics and psychosocial factors where hope and optimism were both positively correlated with increased reported BF/PTG.

Predictors of posttraumatic growth in women with breast cancer

OBJECTIVE

Posttraumatic growth (PTG) is defined as 'positive psychological change experienced as a result of a struggle with highly challenging life circumstances'. The current study examined change in PTG over 2 years following breast cancer diagnosis and variables associated with PTG over time.

METHODS

Women recently diagnosed with breast cancer completed surveys within 8 months of diagnosis and 6, 12, and 18 months later. Linear mixed effects models were used to assess the longitudinal effects of demographic, medical, and psychosocial variables on PTG as measured by the Posttraumatic Growth Inventory (PTGI).

RESULTS

A total of 653 women were accrued (mean age = 54.9, SD = 12.6). Total PTGI score increased over time mostly within the first few months following diagnosis. In the longitudinal model, greater PTGI scores were associated with education level, longer time since diagnosis, greater baseline level of illness intrusiveness, and increases in social support, spirituality, use of active-adaptive coping strategies, and mental health. Findings for the PTGI domains were similar to those for the total score except for the Spiritual Change domain.

CONCLUSION

PTG develops relatively soon after a breast cancer diagnosis and is associated with baseline illness intrusiveness and increases in social support, spirituality, use of active-adaptive coping strategies, and mental health.
