Positive Consequences of Cancer: Exploring Relationships among Posttraumatic Growth, Adult Attachment, and Quality of Life

Post-traumatic stress symptoms, post-traumatic stress disorder, and post-traumatic growth among cancer survivors: a systematic scoping review of interventions

The detrimental effects of Post-Traumatic Stress Symptoms (PTSS) and Post-Traumatic Stress Disorder (PTSD) and the benefits of Post-Traumatic Growth (PTG) are well established for cancer survivors. Increased cancer survival rates necessitate an understanding of how these two paradoxical outcomes, PTSS/PTSD and PTG, are targeted through interventions. This systematic scoping review aims to (a) examine existing evidence on interventions targeting PTSS/PTSD and/or PTG among cancer survivors and (b) identify knowledge gaps to inform future research. Following the six steps of a scoping review, 76 articles met the inclusion criteria. Quantitative articles were examined using descriptive analysis. Frequency counts of the collated data were tabulated into summary tables. Qualitative articles were reviewed using meta-synthesis. Most articles were quantitative (n = 52) and targeted PTG (n = 68) through promising intervention approaches such as psychotherapy, mindfulness, physical activity, and psilocybin-assisted therapy. Three key implications for future research and practice were synthesized: (1) mechanistic considerations for intervention design that provide a roadmap for rigorous and theoretically-grounded research; (2) the need for improved representation of cancer survivors in trials; and (3) potential facilitators of intervention efficacy. Together, these findings can direct future research to optimize interventions to reduce PTSS/PTSD and promote PTG achievement among cancer survivors.

Patient-Factors Influencing the 2-Year Trajectory of Mental and Physical Health in Prostate Cancer Patients

This study aimed to examine the physical and mental Quality of Life (QoL) trajectories in prostate cancer (PCa) patients participating in the Pros-IT CNR study. QoL was assessed using the Physical (PCS) and Mental Component Score (MCS) of Short-Form Health Survey upon diagnosis and two years later. Growth mixture models were applied on 1158 patients and 3 trajectories over time were identified for MCS: 75% of patients had constantly high scores, 13% had permanently low scores and 12% starting with low scores had a recovery; the predictors that differentiated the trajectories were age, comorbidities, a family history of PCa, and the bowel, urinary and sexual functional scores at diagnosis. In the physical domain, 2 trajectories were defined: 85% of patients had constantly high scores, while 15% started with low scores and had a further slight decrease. Two years after diagnosis, the psychological and physical status was moderately compromised in more than 10% of PCa patients. For mental health, the trajectory analysis suggested that following the compromised patients at diagnosis until treatment could allow identification of those more vulnerable, for which a level 2 intervention with support from a non-oncology team supervised by a clinical psychologist could be of help.

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.

A meta-analytic review of the relationship between attachment styles and posttraumatic growth

OBJECTIVE

The present review aimed to examine the relationship between attachment styles and posttraumatic growth in adults exposed to traumatizing events.

METHOD

A systematic literature search resulted in the inclusion of 14 studies in the review. Four correlational meta-analyses of the relationship between the attachment styles of secure, dismissive, preoccupied, and fearful, and posttraumatic growth, were conducted.

RESULTS

These revealed a significant small positive relationship between secure attachment and posttraumatic growth (r =  0.21, p < 0.001); a significant small negative relationship between dismissive attachment and posttraumatic growth (r = -0.12, p < 0.001), and a weak relationship between preoccupied attachment and posttraumatic growth (r = -0.04, p = 0.235), and fearful attachment and posttraumatic growth (r = 0.08, p = 0.248).

CONCLUSIONS

The relationship between attachment styles and posttraumatic growth is modest and may be better explained by other variables. Nonetheless, findings provide useful information for clinicians regarding the potential small impact of attachment style following traumatizing exposure. Implications for future research are highlighted with respect to methodological rigor and the role of other potentially influential variables.

Can military trauma promote psychological growth in combat veterans? Results from the national health and resilience in veterans study

BACKGROUND

Military combat trauma is often associated with negative outcomes, including high rates of posttraumatic stress disorder (PTSD). Less is known, however, about whether military combat trauma may foster posttraumatic growth (PTG), which has been observed in relation to other trauma types, in representative samples of veterans.

METHODS

We analyzed data from veterans who participated in the National Health and Resilience in veterans Study who reported a military-related trauma (n = 210). Participants completed measures of trauma history, combat exposure, PTSD symptoms, PTG, functioning, and quality of life (QOL). Bivariate correlations, regression analyses, analyses of covariance, and fit of linear and quadratic functions were used to examine relationships between PTSD symptom clusters, PTG and its subdomains, and functioning.

RESULTS

Number of deployments (β=0.23) and lifetime PTSD symptom severity (β=0.19), particularly re-experiencing symptoms (β=0.37), were independently associated with greater PTG. An inverted-U-shaped quadratic function provided the best fit for the relationship between PTSD symptoms and PTG (R² =0.22). Greater PTG was associated with greater mental functioning (β=0.15) and QOL (β=0.24).

LIMITATIONS

The inability to make casual inferences in this cross-sectional study; possible bias related to self-report measures; and the lengthy time period between index trauma and assessment of PTSD and PTG.

CONCLUSIONS

PTG is relatively common among combat veterans, particularly among those with PTSD, and is associated with better mental functioning and QOL. Positive psychology interventions to bolster PTG may help promote functional outcomes in this population.

The relationship between posttraumatic growth and health-related quality of life in adult cancer survivors: A systematic review

BACKGROUND

Studies have reported mixed findings on the relationship between posttraumatic growth (PTG) and health-related quality of life (HRQOL) in cancer survivors. This review aims to give an overview of these studies and to identify potential study- and sample-level factors that could contribute to the heterogeneity of those findings on the relationship between PTG and HRQOL in cancer survivors.

METHODS

Multiple electronic databases were systematically searched using the concepts 'posttraumatic growth', 'cancer', and 'health-related quality of life'. Eligible studies (published until 2018) were reviewed, quality-assessed, and effect sizes were extracted and synthesized.

RESULTS

Of the 37 included articles, 22 received a rating of 'weak', 11 'moderate' and 4 'strong' in study quality assessment. The overall sample comprised 7954 individuals, mean age of 55.30 years, >50% females, predominantly breast cancer, and survivors mainly within 5 years post-diagnosis. The synthesized results revealed a positive association between PTG and HRQOL (Fisher's z= 0.16) on a total scale, with significant high heterogeneity (I²=75%). Variations in HRQOL measurement and methodological inconsistency contributed to study-level differences of effect sizes. Sample-level characteristics such as geographic region, smaller sample sizes (n < 100) and so on contributed to heterogeneity.

LIMITATIONS

Studies assessing the relationship between PTG and HRQOL were heterogeneous, of weak study quality generally, and results were difficult to combine.

CONCLUSIONS

Most studies found a positive relationship between the factors suggesting that PTG may play a role for successful coping following cancer. However, studies of higher quality and longitudinal design are needed.

The Traumatic Experience of Breast Cancer: Which Factors Can Relate to the Post-traumatic Outcomes?

Background: Post-traumatic growth (PTG) is considered a positive outcome of struggling with a traumatic event, distinct, and opposite from negative outcomes, i.e., psychological distress. The present study aimed to shed light on the relationship between potentially relating factors (i.e., coping strategies, perceived social support, and attachment style) and both positive and negative psychological outcomes. Methods: A total of 123 breast cancer survivors were recruited, who completed a battery of self-report questionnaires, assessing PTG, psychological distress, coping strategies, perceived social support, and attachment style. Three regression analyses were run to evaluate whether relating factors were significant predictors of the positive and negative psychological outcomes. Results: The regression analyses showed that the "Fatalism" coping strategy and perceived social support were two significant predictors of PTG. Instead, the "Helpless-Hopeless" and "Anxious Preoccupation" coping strategies, as well as an insecure attachment style, were significant predictors of depression, while the "Anxious Preoccupation" coping strategy and an insecure attachment style were significant predictors of anxiety. Conclusions: The present findings showed that the factors underlying a positive or negative outcome are different and specific. While perceived social support and a fatalistic attitude seem to play a key role in the positive outcome, dysfunctional coping strategies, together with an insecure attachment style, appear to be related with negative psychological outcome. Considering these factors in clinical practice would help patients to give meaning to their traumatic experience, enhancing psychological growth.
