Feasibility and acceptability of written exposure therapy in addressing posttraumatic stress disorder in Iranian patients with breast cancer

Interventions strategies and their efficacy in illness perceptions in patients with cancer: A systematic review and meta-analysis

PURPOSES

To identify intervention strategies for improving illness perception (IP) of cancer patients and/or family caregivers; and to examine the effects of IP interventions by meta-analysis.

METHODS

A systematic search was performed to identify literature that focused on improving the IP of cancer patients and/or family caregivers from the establishment of eight databases to August 2023. Manual screening was also applied. The IP intervention strategies for cancer populations were synthesized basing the CSM. Meta-analysis was conducted to assess the effects of IP interventions on health outcomes. Multiple subgroup analyses of the same intervention conditions were conducted to explore the optimal IP-focused intervention.

RESULTS

18 studies were included. 11 studies were conducted in a meta-analysis. No studies on family caregivers' IP were identified. Compared to general care, subgroup analysis revealed that IP interventions had favorable effects on cancer patients' IP as well as quality of life and other outcomes. Six IP intervention strategies (information support, cognitive reframing, emotion adjustment, active coping, effective appraisal, and self-social identification) were generated. Meta-analysis showed that compared with theory-less studies (Z = 8.64, p < 0.01) and single delivery formats (Z = 3.66, p < 0.01), the theory-based interventions (Z = 10.86, p < 0.01) and mixed delivery formats (Z = 7.15, p < 0.01) had higher positive effects on IP outcomes.

CONCLUSIONS

The positive outcomes of IP intervention focusing on cancer patients were highlighted. IP traits and patients' and their caregivers' needs in coping with specific cancer types should be explored before the intervention design. More IP interventions targeting cancer dyads are warranted to develop in the future.

A Novel Intervention to Reduce Fear of Progression and Trauma Symptoms in Advanced Cancer Using Written Exposure to Worst-Case Scenarios

Background: Adults with advanced cancer experience profound future uncertainty, reflected in elevated fear of cancer progression (FoP) and cancer-related trauma symptoms. These symptoms are associated with physical symptom burden and poorer quality of life, and few interventions exist to manage them. Objective: To develop and pilot a written exposure-based coping intervention (EASE) focused on worst-case scenarios among adults with advanced cancer reporting elevated cancer-related trauma symptoms or FoP. Design: A single-arm intervention development and pilot trial. Participants: The trial enrolled 29 U.S. adults with stage III or stage IV solid tumor cancer (n = 24) or incurable or higher-risk blood cancer (n = 5) reporting elevated cancer-related trauma symptoms or FoP. Among those screened, 74% were eligible, with an eligible-to-enrolled rate of 85%. Design/Measurements: EASE was delivered over five 1:1 videoconferencing sessions. Feasibility and acceptability were evaluated via attendance, surveys, and exit interviews. Outcomes were assessed at five time points through 3-month (FU1, main assessment of interest) and 4.5-month (FU2) follow-up. Results: Participant and interventionist feedback was used to iteratively refine EASE. Among participants, 86% (25/29) completed all five sessions and FU1; surveys and exit interviews indicated high acceptability. Primary outcomes of cancer-related trauma symptoms and FoP improved significantly from pre to both follow-ups by predominantly large effect sizes. Secondary outcomes of anxiety, depression, hopelessness, fear of death/dying, and fatigue, and most process measures improved significantly by FU1 or FU2. Conclusions: EASE, a novel adaptation of written exposure therapy, is a promising approach to reducing FoP and cancer-related trauma symptoms among adults with advanced cancer that warrants further study.

Narrative-based autobiographical memory interventions for PTSD: a meta-analysis of randomized controlled trials

Introduction

The aim of this systematic review and meta-analysis is to evaluate the efficacy of narrative-based interventions (NBIs) for individuals with post-traumatic stress disorder (PTSD). Investigating the efficacy of NBIs should yield insight on autobiographical memory (AM) phenomena implicated in PTSD onset and recovery, leading to improved intervention protocols. Furthermore, by analyzing how NBIs influence maladaptive AM distortions, we hope to shed light on the theorized narrative architecture of AM more generally.

Methods

A systematic literature search was conducted according to PRISMA and Cochrane guidelines in MEDLINE, EMBASE, PsychINFO, and PubMed. Additional studies were then also identified from the reference lists of other relevant literature and considered for inclusion. Studies were then evaluated for adherence to the inclusion/exclusion criteria and assessed for risk of bias. Various meta-analyses were performed on included studies to understand how NBIs may or may not influence the overall effect size of treatment.

Results

The results of the meta-analysis of 35 studies, involving 2,596 participants, suggest that NBIs are a viable and effective treatment option for PTSD, yielding a statistically significant within-group effect size and decrease in PTSD symptomatology at both post-treatment [g = 1.73, 95% CI (1.23-2.22)] and 3-9 month follow-up assessments [g = 2.33, 95% CI (1.41-3.26)]. Furthermore, the difference in effect sizes between NBIs compared to active and waitlist controls was statistically significant, suggesting that NBIs are superior. Sub-analyses showed that NET provided a stronger effect size than FORNET, which may be due to the nature of the traumatic event itself and not the treatment protocol. While evidence of small study and publication bias was present, a weight-function model and trim-and-fill method suggested it was not influencing the overall results.

Discussion

This meta-analysis presents strong evidence supporting the use of NBIs in the treatment of PTSD. Clear similarities can be identified between NBIs included in this analysis that make them distinct from non-NBI interventions, which are reviewed in the discussion. Controlled comparisons between NBIs and non-NBIs would help to further understand AM mechanisms of action implicated in recovery and how various interventions facilitate them. Future research should also aim to elucidate the full range of AM impairment in individuals with PTSD to gain insight on how other memory capabilities, such as the ability to mentally simulate the future, are implicated in the pathogenesis of PTSD.

Global psycho-oncology in low middle-income countries: Challenges and opportunities

OBJECTIVES

This Special Issue of Psycho-Oncology is focused on challenges and opportunities in the provision of psychosocial care to patients in low and middle-income countries (LMICs). The aim is to highlight global disparities and inequity in the provision of evidence-based, culturally-sensitive and timely psychosocial care and to showcase the work of researchers and practitioners to address this gap. We hope that this Issue will help to advance the psychological and social dimensions of cancer care in all parts of the world.

METHODS

The focus of the papers is on research and clinical innovations in LMICs that target the psychological, social and cultural dimensions of cancer and on interventions to improve or maintain the psychological well-being, social functioning and/or quality of life of those who are affected and their families.

RESULTS

These papers draw attention to guidelines, resource needs, clinical service evaluation, emerging research and knowledge translation within LMICs that advance knowledge and implementation in the field of psycho-oncology.

CONCLUSIONS

Innovations and advances in psycho-oncology are emerging from LMICs to enhance the care of patients with cancer and their families in these regions and in all parts of the world. A sustained global initiative is now needed to ensure that guidelines for such care are routinely included in global, national and local cancer control plans and that essential resources and attention are directed to implement them.
