OBJECTIVE: Psychological suffering in patients with Malignant Mesothelioma (MM) is different from the one experienced by patients with other cancers due to its occupational or environmental etiology and its peculiar symptomatology and prognosis (i.e., poor prognosis, reduced effectiveness of the therapies, poor quality of residual life, and advanced age at the time of diagnosis). Therefore, the Mesothelioma Psychological Distress Tool-Patients (MPDT-P) has been developed to evaluate the specific profile of psychological suffering in this population. This paper describes the item selection, factor analysis, and psychometric evaluation of the revised MPDT-P.
METHODS: The analyses of the current work aimed to confirm the factorial structure found in the first version of the MPDT-P. In the case of nonfit, it aimed to find an alternative structure and causes of nonfit in the model. The search for the fit of the factorial model was conducted using a Bayesian approach.
RESULTS: The two-factor model reported in the first version of the instrument did not fit the data. Confirmatory Bayesian analyses showed adequate fit for the three-factor solution. Based on the content of the items, we labeled the factors as dysfunctional emotions, claims for justice, and anxieties about the future.
CONCLUSIONS: Integrating the MPDT-P into clinical practice could help clinicians gain insight into the specific suffering related to MM and investigate potential differences related to different occupational and environmental exposure contexts.

OBJECTIVE: Oncologists\' psychological health is a major challenge due to the consequential concerning the quality of the care they provide. However, only critical states of their health have been really examined by scientists. This study sought to plug this gap by investigating the mediating role of psychological flourishing in the relationship between the perception of the professional social context (i.e., perceived workplace isolation and organizational support) and positive attitudes at work among oncologists (i.e., work engagement, task adjustment and empathy).
METHODS: The study was a cross-sectional, including 541 French oncologists. Participants completed a self-report questionnaire. Structural Equation Modeling was employed to test the hypotheses.
RESULTS: The analysis revealed that workplace isolation and organizational support perceptions were related to oncologists\' work engagement, task adjustment and empathy. Additionally, psychological flourishing acted as a partial mediator between these perceptions of professional social context and oncologists\' work-related attitudes.
CONCLUSIONS: This research underlined the potential of enhancing the psychological flourishing of oncologists by improving organizational support and mitigating their sense of isolation, and in turn, to enhance some dimensions of their positive attitudes at work.

OBJECTIVE: To compare and rank the effectiveness of four primary categories of exercise modalities (aerobic, resistance, mind-body, and combined exercise [CE]) in improving the Quality of life (QoL) of women with breast cancer in a network meta-analysis (NMA).
METHODS: Articles published in English and indexed in the PubMed (MEDLINE), EBSCO, Web of Science, SPORTDiscus, The Cochrane Library, Google Scholar, PsycINFO, EMBASE, and CINAHL Plus databases were identified from inception to 12 October 2023. Studies that met the eligibility criteria were assessed for risk of bias. A frequentist NMA was conducted to appraise the efficacy of different exercise types.
RESULTS: This study included 56 studies with 3904 participants. Aerobic, mind-body, and combined exercises effectively improved QoL compared to controls. The surface under the cumulative ranking curve (SUCRA) indicated that CE best improved patients\' QoL (SUCRA = 96.7%). Analysis of the secondary outcomes suggests that exercise reduced patients\' depression (standardized mean difference [SMD] = -0.38, 95% confidence interval [CI] = -0.70 to -0.06, p < 0.001; I2 = 79%) and anxiety (SMD = -0.50, 95% CI = -0.69 to -0.31, p < 0.001; I2 = 27.4%) but did not affect self-esteem.
CONCLUSIONS: All exercise types but resistance were effective in improving the QoL of women with breast cancer, CE (the combination of aerobic and resistance exercise) had the highest likelihood of being optimal for improving QoL.

BACKGROUND: Cancer in a loved one can have negative effects on child health and development. Child Life Specialists (CLSs) specialize in assisting children understand and cope with difficult medical scenarios but are generally not available in adult care facilities to support the needs of patient-families with minor children. We conducted a mixed-methods study of the implementation of a pilot CLS program at a tertiary oncology centre.
METHODS: We collected administrative and clinical data on referred families; encounter data; and patient-reported questionnaire data before and 2 months after engagement with the program.
RESULTS: Over the initial 10 months, 98 families were referred, 91 of whom engaged through a total of 257 clinical encounters. The cancer patient in the family was most commonly a woman with a mean age of 45 years and in the role of mother. Breast cancer was the most common diagnosis (24%) and 78% of patients had stage IV disease. Most families had >1 child at home, and children were most commonly school-aged (5-14y). Phone and Hospital/Clinic visits accounted for the largest portion of CLS time. Interventions ranged from diagnosis education through to bereavement support. Most cancer patients indicated that the program was helpful to them and their families. There were trends of moderate improvements on patient reported outcomes.
CONCLUSIONS: Our study was able to provide an understanding of the initial CLS program operations to guide program development and future study. Such a program holds promise as an important aspect of adult oncology family-centered care.

METHODS: A multi-methods, single-centre pilot comprising a quasi-experimental pre-/post-test design and an exploratory qualitative study.
METHODS: A rural Australian hospital and health service.
METHODS: Men newly diagnosed with localised prostate cancer who were scheduled to undergo, or had undergone, radical or robotic prostatectomy surgery within the previous 3 months.
METHODS: The intervention comprised a 12-week virtual care program delivered via teleconference by a specialist nurse, using a pre-existing connected care platform. The program was tailored to the post-operative recovery journey targeting post-operative care, psychoeducation, problem-solving and goal setting.
METHODS: Primary outcome: program acceptability.
RESULTS: quality of life; prostate cancer-related distress; insomnia severity; fatigue severity; measured at baseline (T1); immediately post-intervention (T2); and 12 weeks post-intervention (T3).
RESULTS: Seventeen participants completed the program. The program intervention showed very high levels (≥4/5) of acceptability, appropriateness and feasibility. At T1, 47% (n = 8) of men reported clinically significant psychological distress, which had significantly decreased by T3 (p = 0.020). There was a significant improvement in urinary irritative/obstructive symptoms (p = 0.030) and a corresponding decrease in urinary function burden (p = 0.005) from T1 to T3.
CONCLUSIONS: This pilot has shown that a tailored nurse-led virtual care program, incorporating post-surgical follow-up and integrated low-intensity psychosocial care, is both acceptable to rural participants and feasible in terms of implementation and impact on patient outcomes.

OBJECTIVE: This Special issue of Psycho-Oncology highlights examples of the application of implementation science to research in psycho-oncology. The aim is to demonstrate the different ways that implementation science is being used to generate evidence that can more readily translate evidence into changes in clinical practice. We hope this issue fosters greater interest in using the tools of implementation science to improve the lives of people affected by cancer.
METHODS: The papers in the issue were selected from among those that responded to a call for submissions on the application of implementation science frameworks and methods to issues in psycho-oncology. The focus included but was not limited to research on: understanding barriers and facilitators of intervention/practice adoption; assessing implementation outcomes, evaluating implementation strategies, and improving behavioural and/or clinical outcomes.
RESULTS: The 11 papers in this issue were grouped for presentation purposes into four common topics: barriers and facilitators to implementation; feasibility as a key implementation outcome; the design, selection and adaptation of implementation strategies; and building the foundation for psycho-oncology research translation via systematic reviews that focus on implementation strategy design.
CONCLUSIONS: These papers demonstrate the breadth of current applications of implementation science to research in psycho-oncology. Alongside the studies featured in this issue, including cost-effectiveness analyses, tests of nationally-focused strategies and proactive planning for adaptation, we look forward to other innovations that will promote further growth of both disciplines to improve the integration of psycho-oncology interventions across healthcare systems.

OBJECTIVE: Clinical fear of cancer recurrence (FCR) was recently defined by a group of experts during a Delphi study. Five criteria were agreed upon, namely: (a) high levels of preoccupation, (b) high levels of worry, (c) that are persistent, (d) hypervigilance and hypersensitivity to physical sensations that e) may result in functional impairment. No existing instruments comprehensively capture all these criteria for clinical FCR.
METHODS: To remedy this gap, a set of three patient-reported outcome instruments including a one-item screener, self-report questionnaire, and semi-structured clinical interview, named the Ottawa Clinical Fear of Recurrence instruments, were developed. To do so, the research team first conducted a literature review of potential items. Additional FCR experts discussed the content of the screener and interview. The self-report\'s items were assessed for content validity by the same expert panel using Likert ratings and the Content Validity Index to narrow down the number of items. The three instruments were piloted with a group of cancer survivors to assess face validity following the European Organization for Research and Treatment of Cancer recommendations.
RESULTS: The literature review and content validity assessment led to a final draft pre-pilot of 23 potential items for the self-report questionnaire. The instruments were piloted. Pilot study participants suggested changing wording and response options (particularly for the self-report) for greater clarity.
CONCLUSIONS: Based on the feedback received, minor modifications were made, mostly for the self-report. In general, content and face validity for the three instruments were good for both experts and cancer survivors.

BACKGROUND: Symptoms of cancer-related fatigue (CRF) can have a significant impact on patients\' quality of life and treatment adherence. We aimed to investigate the relationship between CRF and multiple psychosocial and somatic indicators within a large mixed cancer sample.
METHODS: In this cross-sectional study, N = 1787 outpatients with cancer were assessed for CRF, pain, anxiety, and depression using validated screening instruments. We further obtained clinical parameters (Hb, CRP, creatinine, leukocytes, ASAT, and ALAT), sociodemographic data (age, gender, income, education level, marital status, parenthood, and living area), and lifestyle factors. Multivariate linear regression models were applied to estimate the impact of each indicator on CRF.
RESULTS: Overall, 90.6% of patients experienced some CRF, with 14.8% experiencing severe CRF. No gender difference was found in the prevalence of CRF. Patients with higher levels of pain, depressive symptoms, and lower Hb levels had significantly higher levels of CRF (ps <0.001). Lower levels of CRF were observed in patients who had children (p = 0.03), had less education (p < 0.001), and were physically active for more than 2 h per week before their oncological diagnosis (p = 0.014). The latter was only a significant indicator in the male subsample.
CONCLUSIONS: The present results demonstrate a high prevalence of CRF and highlight that not only somatic and psychosocial factors, but also lifestyle factors prior to diagnosis appear to be associated with the etiology and persistence of CRF. To effectively treat CRF, a biopsychosocial, personalized approach is recommended.

OBJECTIVE: To identify predictors of sexual satisfaction in patients with advanced cancer and their family caregivers.
METHODS: Cross-sectional study using baseline survey data from a randomized controlled trial in six European countries. Patients with advanced cancer and their family caregiver completed measures on sexual satisfaction (one item from Functional Assessment of Cancer Therapy - General questionnaire for patients and Caregiver Quality of Life Index-Cancer scale for family caregivers) and health-related characteristics. Multivariable linear regressions were performed for all predictors (identified based on literature) with sexual satisfaction as dependent variable.
RESULTS: The sample comprised 431 patient-family caregiver dyads. Patients with prostate or gynecological cancer reported lower sexual satisfaction (respectively B = -0.267 95% CI: -1.674, -0.594 and B = -0.196, 95% CI -2.103, -0.452). Higher emotional (B = 0.278, 95% CI 0.024, 0.057) physical (B = 0.305, 95% CI 0.012, 0.025) and social functioning (B = 0.151, 95% CI 0.001, 0.013), global health (B = 0.356, 95% CI 0.007, 0.013) and social wellbeing (B = 0.161, 95% CI 0.013, 0.082) among patients were associated with higher sexual satisfaction. Among family caregivers, sexual satisfaction was lower with increased age (B = -0.142, 95% CI -0.022, -0.004). Higher emotional functioning (B = 0.027, 95% CI 0.011, 0.043) and quality of life (B = 0.165, 95% CI -0.165, 0.716) were associated with higher sexual satisfaction in family caregivers.
CONCLUSIONS: The results underscore that sexual wellbeing of patients and family caregivers is related to health related factors in physical, emotional, and social domains. Patients and family caregivers could benefit from a dyadic approach to address sexual wellbeing.

OBJECTIVE: In Germany, children diagnosed with cancer survive their initial disease in more than 80%, and the majority will become long-term survivors. Around the age of 18, survivors are transferred to adult healthcare. The transition can be a critical period in the process of care at which many childhood cancer survivors discontinue to participate in regular follow-up care. Hence, the objective of the paper was to explore (a) survivors\' attitudes towards pediatric follow-up care and (b) their concerns regarding the transition process to draw conclusions for optimizing pediatric care and transition processes.
METHODS: We conducted semi-structured interviews with 21 adolescent childhood cancer survivors between the ages of 14 and 20. The survivors were recruited via a pediatric oncology department of a university hospital in Germany. Based on the principles of qualitative content analysis, a deductive-inductive method according to Kuckartz was applied.
RESULTS: Based on the interview guide and derived from the exploratory research questions, two key categories were generated: (a) Survivors\' attitudes towards pediatric follow-up care, which encompasses all formal and emotional aspects of survivors regarding follow-up care, and (b) their concerns regarding transition from pediatric to adult healthcare, where hindering and facilitating factors for a successful transition occur. Our results show high satisfaction among survivors with follow-up care. Nevertheless, they wish to be more integrated into processes and the organization of their follow-up care. Most adolescent survivors do not feel ready for transition.
CONCLUSIONS: The integration of survivors into the organization processes and routines, and the promotion of emotional detachment from pediatric health care professionals (HCPs) are important to reduce concerns and uncertainties of adolescent survivors regarding the transition process and to promote subjective readiness for transition. To gain confidence in the adult healthcare, it is crucial to provide tailored education depending on individual requirements and needs and to build trusting relationships between survivors and adult HCPs.
