Psychological Distress after a Diagnosis of Malignant Mesothelioma in a Group of Patients and Caregivers at the National Priority Contaminated Site of Casale Monferrato

Psychological Distress in Patients With Asbestos-Related Diseases and Their Families: A Systematic Literature Review

BACKGROUND

Exposure to asbestos in the workplace is currently recognized as one of the leading causes of work-related deaths, with more than half of deaths attributable to cancer.

AIMS

The aim of this systematic literature review was to investigate the mental health and psychological distress of patients affected by asbestos-related diseases and their caregivers.

METHODS

The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The studies were identified in October 2023 by searching four electronic databases: Scopus, Web of Science, PubMed and PsycInfo/PsycArtcicles. Risk of bias was assessed using the JBI checklist.

RESULTS

Fourteen articles were identified. The studies focused exclusively on the psychological distress of patients with malignant mesothelioma (MM) and their caregivers. MM appears to have traumatic effects on both patients and caregivers, who may experience anxiety and depression, an impoverished emotional life, somatization, social withdrawal, and a deterioration in their quality of life. In addition, a need for information about MM, its progression and associated care tasks was identified, and patients and caregivers reported frequently seeking information from online sources.

CONCLUSIONS

Our review has shown that there are still few studies addressing psychological distress in MM patients and their caregivers, and none addressing distress in the context of other asbestos-related diseases. The somatopsychic consequences of MM in patients and caregivers should encourage institutions and health professionals to develop assessment and intervention models that are tailored to the specific suffering and needs of MM patients and their caregivers and promote their residual vitality.

Rediscovering one's own voice in a brief psychoanalytic group intervention aimed at malignant mesothelioma patients and their families

Occupational and/or environmental exposure to asbestos can lead to clinical manifestation of a variety of diseases, including malignant mesothelioma (MM), a rare cancer with a particularly high incidence rate in areas with a long history of asbestos processing. This paper aims to describe brief psychoanalytic groups (BPGs), which is an intervention model aimed at MM patients and their families in the early stages of the disease, shortly after diagnosis. The BPG model comprises 12 weekly sessions of 1 h each, co-led by two psychoanalytically oriented psychotherapists who are trained in working with cancer patients and their families and in the specifics of the BPG setting. Reflections in this paper on the BPGs will attempt to trace the voice of the group in clinical material, paying attention to its horizontal unfolding as a melodic development over time and its vertical unfolding as a harmonic interweaving between the different individual voices, which, even when opposed to each other, can find a generative interlocking of meaning. In the BPG, then, it is possible to set in motion transformations that allow one to embrace the different and diverse affective colorations of experience, evolve toward a thinking that is capable of incorporating intense emotions related to death and grief, follow healthier paths of interaction on an intrapsychic and interpersonal level, and find traces of one's own vitality.

Psychological Interventions for Mesothelioma Patients and Their Caregivers: A Systematic Literature Review

Malignant Mesothelioma (MM) has a striking impact on the somatopsychic balance of patients and their families, including physical, psychological, and interpersonal problems. The aim of this systematic literature review was to investigate what psychological interventions are offered to patients with MM and their caregivers worldwide.

METHODS

The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The literature search led to the identification of 12 articles. Results were categorized into five categories. 1. Individual psychological support, 2. Group psychological support, 3. Cognitive-behavioral group psychotherapy, 4. Brief psychoanalytic groups, 5. Multifamily group.

RESULTS

The interventions differed in terms of form, duration and resources used. Most of them were group-based and psychoanalytically oriented, although individual and cognitive-behavioral interventions were also described. Despite the differences, the interventions appeared to be fundamental in facilitating the processing of mental pain and anger related to the diagnosis.

CONCLUSION

Our study has shown that there are still few psychological interventions available for MM patients and their caregivers. The somatopsychic consequences of MM in patients and caregivers should encourage institutions and healthcare professionals to develop assessment and intervention models that address the different dimensions of their suffering and promote their residual vitality.

Confirmatory validation of a brief patient-reported outcome measure assessing psychological distress in caregivers of malignant mesothelioma patients: the Mesothelioma Psychological Distress Tool-Caregivers

Objective

The diagnosis of malignant mesothelioma (MM) can be devastating for both patients and caregivers, who may experience intense suffering from a physical, psychological, and interpersonal perspective. Despite the extensive literature on caregiver distress, there is a lack of validated measures to provide evidence of psychological distress of caregivers of MM patients. Therefore, in a previous study we developed the Mesothelioma Psychological Distress Tool-Caregivers (MPDT-C) to evaluate the specific profile of psychological distress in this population. This paper describes the item selection, factor analysis, and psychometric evaluation of the revised MPDT-C.

Methods

The analyses of this work first aimed to confirm the previous factorial structure. In the case of nonfit, it aimed to find an alternative structure and causes of nonfit in the model. Examination of the fit of the factorial model was conducted using a Bayesian approach.

Results

The final version of the MPDT-C is a 7-item self-report questionnaire consisting of one factor (Burden for the caregiver).

Conclusion

Having a short self-report questionnaire to assess the psychological distress experienced by caregivers of MM patients has several advantages. First, it is suited to epidemiological studies where multiple variables and measures are involved. Second, it is easy to administer and does not take much time to complete. Therefore, the MPDT-C can also be administered in clinical contexts, perhaps when MM patients attend follow-up medical evaluation. Lastly, short measures are less affected by cognitive fatigue, which is very common in a long battery of tests and could affect response reliability.

Relationships among self-disclosure, social support and psychological distress in caregivers of patients with advanced lung cancer: A mediating model

OBJECTIVES

To examine the relationship between self-disclosure, social support, and psychological distress among caregivers of patients with advanced lung cancer, the study also examined the factors that impact psychological distress and the effect of social support on the relationship between self-disclosure and psychological distress.

METHODS

A total of 288 caregivers of patients with advanced lung cancer were selected using a convenience sampling method from December 2022 to July 2023 at a tertiary hospital in China. Participants' self-disclosure, perceived social support, and psychological distress were assessed by corresponding questionnaires, respectively. Mediating effects were detected using Amos 26.0 software.

RESULTS

The total scores for psychological distress, perceived social support, and self-disclosure of caregivers were 28.62 ± 6.45, 55.22 ± 7.81, and 38.39 ± 5.64, respectively. Correlation analysis suggested that psychological distress in caregivers was negatively correlated with both perceived social support and self-disclosure. Multiple linear regression analyses revealed that self-disclosure and perceived social support were influential factors of caregivers' psychological distress. Moreover, perceived social support partially mediated the relationship between self-disclosure and psychological distress, accounting for 54.37% of the total effect.

CONCLUSION

Caregivers of patients with advanced lung cancer experience significant psychological distress. Self-disclosure can affect caregivers' psychological distress directly and indirectly through perceived social support. Healthcare professionals should be attentive to caregivers' psychological distress and carry out relevant nursing measures to improve caregivers' self-disclosure and social support to promote their physical and mental health.

Rehabilitation for Functioning and Quality of Life in Patients with Malignant Pleural Mesothelioma: A Scoping Review

Malignant pleural mesothelioma (MPM) represents a significant clinical challenge due to limited therapeutic options and poor prognosis. Beyond mere survivorship, setting up an effective framework to improve functioning and quality of life is an urgent need in the comprehensive management of MPM patients. Therefore, this study aims to review the current understanding of MPM sequelae and the effectiveness of rehabilitative interventions in the holistic approach to MPM. A narrative review was conducted to summarize MPM sequelae and their impact on functioning, disability, and quality of life, focusing on rehabilitation interventions in MPM management and highlighting gaps in knowledge and areas for further investigation. Our findings showed that MPM patients experience debilitating symptoms, including fatigue, dyspnea, pain, and reduced exercise tolerance, decreasing quality of life. Supportive and rehabilitative interventions, including pulmonary rehabilitation, physical exercise improvement, psychological support, pain management, and nutritional supplementation, seem promising approaches in relieving symptoms and improving quality of life but require further research. These programs emphasize the pivotal synergy among patient-tailored plans, multidisciplinary team involvement, and disease-specific focus. Despite advancements in therapeutic management, MPM remains a challenging disease with limited effective interventions that should be adapted to disease progressions. Rehabilitative strategies are essential to mitigate symptoms and improve the quality of life in MPM patients. Further research is needed to establish evidence-based guidelines for rehabilitative interventions tailored to the unique needs of MPM patients.

The psychological impact of diagnosis of sinonasal, nasopharyngeal, and laryngeal cancers: a systematic review

Objective

High risk of degraded quality of life and psychological distress is observed in patients diagnosed with sinonasal, nasopharyngeal, and laryngeal cancers, which could be caused by exposure to carcinogens in workplaces. This review aimed to investigate the psychological impact of diagnosis associated with the possible occupational etiology of such neoplasms and to explore the instruments that evaluate the quality of life (QoL), anxiety, and depression in these patients.

Methods

Studies were considered for the review only if they described aspects of the psychological impact of the diagnosis of sinonasal, nasopharyngeal, and laryngeal cancers and reported results distinguished by the tumor site. The psychological impact was assessed in terms of health-related QoL, anxiety, and depression using reliable psychometric questionnaires administered at the time of diagnosis and 1 year later.

Results

In more than 5,900 records identified, 442 studies fulfilled the eligibility criteria and 436 were excluded after full-text screening, resulting in six studies to be finally included in the review. The EORTC Core Quality of Life questionnaire (EORTC QLQ-C30), EORTC QLQ-H&N35, and Functional Assessment of Cancer Therapy (FACT) were used to evaluate the QoL, whereas the Hospital Anxiety and Depression Scale (HADS) and Center for Epidemiologic Studies Depression Scale (CES-D) questionnaires were employed to assess anxiety and depression. QoL scores were similar to those of the general population at the time of diagnosis and remained unchanged or slightly improved at 1 year since diagnosis. In contrast, a higher prevalence of anxiety and depression was observed compared with the general population, although the results were inconsistent across the very few studies identified. No study investigating the association between the potential occupational etiology and QoL or distress was found.

Conclusion

Exploring the existing scientific literature on emotional distress in sinonasal, nasopharyngeal, and laryngeal cancer patients was prompted by concerns over the disfiguring nature of treatment and the additional emotional burden resulting from their occupational etiology. Unfortunately, neither a crucial element nor other risk factors (lifestyle, smoking, drinking, etc.) were examined in any study. Patients' employment history should be considered in order to assess the possible impact of believing they are affected by an occupational exposure disease in the evaluation of their psychological distress. This history would support evidence-based recommendations about dedicated psychological interventions.

Confirmatory validation of the Mesothelioma Psychological Distress Tool-Patients: A brief patient-reported outcome measure assessing psychological distress in malignant mesothelioma patients

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.

Mental health and wellbeing in mesothelioma: A qualitative study exploring what helps the wellbeing of those living with this illness and their informal carers

PURPOSE

Mesothelioma is an incurable, asbestos related cancer with a poor prognosis. Little is known about how patients and carers living with the condition manage their mental health and wellbeing needs. This paper reports findings on interventions being used by patients and informal carers living with mesothelioma and those which they find most helpful.

METHODS

In-depth interviews with patients (n = 10) and (informal) carers (n = 11) living with mesothelioma in the UK. We analysed our data inductively using a reflexive thematic analysis approach.

RESULTS

Participants described the importance of both smaller and larger actions and strategies which helped with their mental health. This included spending more time with family and friends and going on holidays. Professionals who participants said supported their mental health journey included not only specialist nurses and mental health professionals but also legal and Asbestos Support Group professionals. The latter demonstrates the unique needs and support required for this population. Exposure to asbestos as the cause of mesothelioma, has led to a social justice aspect of the experience of living with this cancer. Participants reported the importance of collective action to their mental health and wellbeing. The data indicate that patients and carers may have distinct mental health and wellbeing requirements and need to manage these in different ways at different times.

CONCLUSIONS

Findings have implications for nurses and other key professionals working in healthcare, community and legal settings supporting this client group, and for those living with mesothelioma who want to understand ways to enhance their own wellbeing.

The mental health and well-being implications of a mesothelioma diagnosis: A mixed methods study

PURPOSE

Mesothelioma is an incurable, asbestos-related cancer with a poor prognosis. There is scant evidence about the mental health and well-being impacts on patients and carers living with the illness. This study aimed to investigate mesothelioma's impact on mental health and well-being and the scale of mental health conditions in patients and informal carers.

METHODS

A mixed-methods design was used: a cross-sectional survey of mesothelioma patients and informal carers plus semi-structured interviews with patients and carers. The survey used validated scales collecting data on mental health aspects of mesothelioma: the EQ5D to assess health-related quality-of-life; the Hospital Anxiety and Depression scale; the PCL-5 to assess Posttraumatic Stress; and the Posttraumatic Growth Inventory. The datasets were integrated during analysis.

RESULTS

96 useable survey responses were received. A clinical level of depression was reported by 29 participants (30.21%), of anxiety by 48 (50%), of posttraumatic distress disorder by 32 (33.33%), and of posttraumatic growth by 34 (35.42%). Carers had worse scores than patients. Three main themes were developed from interviews with 10 patients and 11 carers: 'Prognosis', 'Support from services', and 'Social connections and communication'.

CONCLUSIONS

Healthcare professionals delivering a mesothelioma diagnosis require regular training in communication skills plus updating in current treatment options, so they provide an appropriate mix of realism and hope. Better signposting to mental health support is needed for patients and carers. Our introduction of posttraumatic growth into the mesothelioma literature is novel. We recommend specialist nurses are trained to recognise, understand, and foster posttraumatic growth.

The psychological impact of sarcoma on affected patients

OBJECTIVE

Sarcoma diagnosis and its treatment trajectory may deeply affect the somatopsychic balance of patients and their caregivers. This systematic review aimed at deepening the understanding of sarcoma's impact on the entire family unit involved in the illness experience on a physical (e.g. fatigue), psychological (e.g. mental health, affective regulation, defense mechanisms), and interpersonal (e.g. social isolation, loneliness) level.

METHODS

The systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The literature search led to the identification and subsequent inclusion of 44 articles focused on sarcoma patients. Results were classified into seven categories: Quality of Life, worries and distress, anxiety and depression, suicide ideation, financial and occupational consequences, unmet needs, and coping strategies. Our search identified only one study focusing on informal caregivers, thus we could not perform a systematic review on these results.

RESULTS

Our findings underlined the traumatic impact of the sarcoma diagnosis. Patients can experience an impoverished emotional life, somatization, social withdrawal, difficulty in decision-making, increased feelings of discouragement and demoralization, and profound experiences of helplessness and vulnerability. Moreover, they seemed to display anxiety and depression and might present a higher suicide incidence than the general population.

CONCLUSION

Our review highlighted that the psychosocial aftermath of sarcoma patients should guide institutions and healthcare professionals toward the design of assessment and intervention models that could contemplate the different dimensions of their suffering. Furthermore, it points out that there is still a lack of evidence regarding the psychosocial impact affecting sarcoma patients' caregivers.

Caregivers of patients with malignant pleural mesothelioma: who provides care, what care do they provide and what burden do they experience?

PURPOSE

There are limited data on the impact of caregiving for patients with malignant pleural mesothelioma (MPM) on the caregiver. We aimed to identify the demographic characteristics of these caregivers, the caregiving activities they perform and how caregiving burden impacts their work productivity and overall activity.

METHODS

This cross-sectional study collected data from caregivers of patients with MPM across France, Italy, Spain and the United Kingdom January-June 2019. Caregiver demographics, daily caregiving tasks and the impact of caregiving on physical health was collected via questionnaire. The Zarit Burden Interview (ZBI) was used to assess caregiver burden and the Work Productivity and Activity Impairment questionnaire (WPAI) assessed impairment at work and during daily activities. Analyses were descriptive.

RESULTS

Overall, 291 caregivers provided data. Caregivers were mostly female (83%), living with the patient (82%) and their partner/spouse (71%). Caregivers provided over five hours of daily emotional/physical support to patients. ZBI scores indicated 74% of caregivers were at risk of developing depression. Employed caregivers had missed 12% of work in the past seven days, with considerable presenteeism (25%) and overall work impairment (33%) observed. Overall, the mean activity impairment was 40%.

CONCLUSION

Caregivers provide essential care for those with MPM. We show caregiving for patients with MPM involves a range of burdensome tasks that impact caregivers' emotional health and work reflected in ZBI and WPAI scores. Innovations in the management of MPM must account for how caregivers may be impacted and can be supported to carry out this important role.

Mesothelioma patient and carer experience research: A research prioritisation exercise

OBJECTIVES

Incidence of mesothelioma worldwide is growing and the UK reports the highest global incidence. Mesothelioma is an incurable cancer with a high symptom burden. However, it is under researched when compared to other cancers. The aim of this exercise was to identify unanswered questions about the mesothelioma patient and carer experience in the UK and to prioritise research areas of most importance through consultation with patients, carers and professionals.

MATERIALS AND METHODS

A virtual Research Prioritisation Exercise was conducted. This involved a review of mesothelioma patient and carer experience literature to identify research gaps and a national online survey to identify and rank research gaps. Following this, a modified consensus method with mesothelioma experts (patients, carers and professionals from healthcare, legal, academic and volunteer organisations) was undertaken to reach a consensus regarding mesothelioma patient and carer experience research priorities.

RESULTS

Survey responses were received from 150 patients, carers and professionals and 29 research priorities were identified. During consensus meetings, 16 experts refined these into a list of 11 key priorities. The five most urgent priorities were symptom management, receiving a mesothelioma diagnosis, palliative and end of life care, treatment experiences, barriers and facilitators to joined up service provision.

CONCLUSION

This novel priority setting exercise will shape the national research agenda, contribute knowledge to inform nursing and wider clinical practice and ultimately improve the experiences of mesothelioma patients and carers.

Preliminary validation of a brief PROM assessing psychological distress in patients with malignant mesothelioma: The mesothelioma psychological distress tool-Patients

Objective

Psychological suffering in malignant mesothelioma (MM) differs from that in other cancers because of its occupational etiology, and we aimed to develop specific patient-reported outcome measures to assess it.

Methods

We used a multi-method prospective observational multicentric study (N = 149), and a preliminary questionnaire validation was performed through a Bayesian approach.

Results

Item analysis showed a good internal consistency and reliability (Cronbach alpha = 0.79 [95% CI = 0.74-0.93]. Twenty of the 41 initial items were selected as posterior 95% highest density interval factor loading standardized effect size fell outside of the region of practical equivalence. Bayesian exploratory factor analysis showed a two-factor structure: (1) Trauma-related reactions (TR, 13 items) and (2) Claim for justice (CJ, 7 items), confirmed by the Bayesian confirmatory factor analysis. Latent factors were poorly correlated (Posterior median: 0.13; 95% CI = -0.079 to 0.323). The 90% root mean square error of approximation posterior median was 0.04 [90% CI = 0.03-0.58]; the 90% chi-square posterior median was 242 [90% CI = 209-287].

Conclusion

Psychological suffering in MM patients implies negative cognitive, emotional, and somatic reactions related to the traumatic impact of the disease and the need to obtain justice through economic compensation. Our findings provide preliminary evidence that the Mesothelioma Psychological Distress Tool-Patients could be a promising and reliable instrument to assess MM patients' psychological distress.

Depression and Complicated Grief, and Associated Factors, of Bereaved Family Members of Patients Who Died of Malignant Pleural Mesothelioma in Japan

OBJECTIVES

we investigated the prevalence and associated factors of depression and complicated grief (CG) among bereaved family members of malignant pleural mesothelioma (MPM) patients in Japan.

METHODS

Bereaved family members of MPM patients (n = 72) were surveyed. The Japanese version of the Patient Health Questionnaire-9 (PHQ-9) and the Japanese version of the Brief Grief Questionnaire (BGQ) were used to assess depression and complicated grief (CG), respectively. Socio-economic factors, anger toward asbestos, care satisfaction, achievement of good death, and quality of end-of-life care were assessed in relation to depression and CG.

RESULTS

In the family members of MPM patients, the frequencies of depression and CG were 19.4% and 15.3%, respectively. The bereaved family members who were not compensated by the asbestos-related health-damage relief system (p = 0.018) and who felt the financial impacts of the patient's MPM on the family (p = 0.006) had a higher likelihood of depression. The bereaved family members who were not satisfied with the care given when the patient became critical (p = 0.034), who were not compensated by the asbestos-related health-damage relief system (p = 0.020), who felt the financial impact of the patient's MPM on the family (p = 0.016), and whose deceased relative underwent surgery (p = 0.030) had a higher likelihood of CG.

CONCLUSIONS

For bereaved family members of MPM patients, routine screening for depression and CG and the provision of grief care are suggested. In addition, for family members of MPM patients, financial support, including the promotion of the asbestos-related health-damage relief system, and improved care for patients who undergo surgery and when patients become critical, are recommended.

Patients' and informal carers' experience of living with mesothelioma: A systematic rapid review and synthesis of the literature

PURPOSE

Mesothelioma is a rare and incurable cancer linked to asbestos exposure. It primarily affects the pleura. This systematic rapid review aimed to identify what is known about the experience of living with mesothelioma, from the perspective of patients and their informal carers.

METHODS

Medline, PsycInfo, Scopus and the Cumulative Index to Nursing and Allied Health Literature were searched for empirical studies published between December 2008 and October 2020. Google Scholar was searched. The inclusion criteria stated that studies were peer-reviewed, reported the experience of living with mesothelioma from the perspective of patients and carers and written in English. The Mixed-Methods Appraisal Tool was used to assess quality. The review protocol is registered on PROSPERO: CRD42020204726.

RESULTS

Twenty-five studies met the inclusion criteria. Following data extraction, a narrative synthesis identified three themes: the impact on the individual; the impact on informal carers and relationships; and interactions with professionals and systems. The physical and psychological symptom burden of mesothelioma on patients' lives was reported as high. Both the qualitative and quantitative literature highlighted that patients and carers may have different needs throughout the mesothelioma journey. Differences included psychological experiences and preferences regarding the timing of information and support provision. Patients and carers expected their health care professionals to be knowledgeable about mesothelioma or refer to those who were. Health care professionals that were compassionate, honest and supportive also positively influenced the experience of patients and carers living with mesothelioma. A lack of communication or misinformation was damaging to the patient-healthcare professional relationship. Continuity of care, coordinated care and good communication between treatment centres were widely reported as important in the literature. Fragmented care was identified as detrimental to the patient experience, increasing anxiety in patients. However, relationships with professionals were not only important in terms of co-ordinating care. There was also evidence that good relationships with healthcare professionals were beneficial to coping with the mesothelioma diagnosis.

CONCLUSION

The volume of mesothelioma experience research has grown over the past decade. This has led to our growing understanding of the complex needs and experiences of mesothelioma patients and carers. However, this review identified several evidence gaps.

Systematic Review and Meta-Analysis of Prevalence of Depression Among Caregivers of Cancer Patients

BACKGROUND

Caregivers of cancer patients commonly experience depressive symptoms due to the heavy burden of caregiving responsibility.

OBJECTIVE

This meta-analysis examined the prevalence of depression among caregivers of cancer patients.

METHODS

We included 85 studies covering 23,317 participants published between 2001 and 2021 (25 countries) that reported the prevalence of depression among caregivers of cancer patients. We examined the pooled prevalence of depression and hypothesized moderators, including year, age, sex, geographic regions, percentage of spousal caregivers, depression measures, and cancer stage.

RESULTS

All 85 effect sizes included 6,077 caregivers of patients with depression. The weighted average prevalence of depression was 25.14% (95% CI, 21.42-29.27%) among caregivers. The prevalence rates were moderated by geographic region, patients' cancer stage, and measures for depression. The prevalence rates also varied among the different measures assessing depression. The prevalence rate decreased with the mean age of the caregivers and the percentage of spousal caregivers.

CONCLUSIONS

This study revealed a high prevalence of depression among caregivers of cancer patients. The prevalence rates also varied with the study design, demographics of caregivers, and patients' medical information. These findings highlight that psychological support and intervention may be crucial for patients and their caregivers in clinical practice.

Preliminary validation of a questionnaire assessing psychological distress in caregivers of patients with malignant mesothelioma: Mesothelioma Psychological Distress Tool-Caregivers

OBJECTIVE

To develop a short, flexible, and comprehensive tool to measure psychological distress in caregivers of malignant mesothelioma (MM) patients: the Mesothelioma Psychological Distress Tool-Caregivers version (MPDT-C).

METHODS

Based on a systematic review of the relevant literature, aspects associated with caregiver distress were derived. Expert researchers/clinicians developed a pool of items for each identified aspect. Content validity was assessed through a multiple mixed-methods approach. A multicenter study was conducted to explore the factorial structure of the 47-item MPDT-C through Bayesian factor analysis.

RESULTS

The Bayesian exploratory factor analysis revealed an underlying three-factor structure. Factors were labeled Secondary Traumatic Stress, Engagement in Caring, and Meaningful Cognitive Restructuring. All scales showed sufficient reliability and corrected item-total correlations. Females scored higher than males for Engagement in Caring.

CONCLUSIONS

Taking care of malignant mesothelioma patients is a stressful process that influences the caregiver's physical, emotional, and social wellbeing. Our study offers preliminary evidence in support of the adequate psychometric properties of the MPDT-C, and these should now be replicated. Results suggest that the MPDT-C is a reliable tool with which to detect the psychological distress of this traumatized population.

The psychosocial impact of living with mesothelioma: Experiences and needs of patients and their carers regarding supportive care

OBJECTIVE

Mesothelioma is a rare cancer with a poor prognosis caused by exposure to asbestos. Psychosocial support and care for mesothelioma patients and their carers is limited and not tailored to their specific needs. The aim of this study was to explore patients' and carers' needs and experiences regarding psychosocial support and their coping mechanisms dealing with psychosocial problems.

METHODS

A qualitative study was performed using semi-structured interviews with both mesothelioma patients and their carers. Participants were recruited through two specialised hospitals and two patient organisations. All interviews were transcribed verbatim and thematically analysed.

RESULTS

Ten patients (70% male, mean age 67.7) and five carers (20% male, mean age 65) participated in the study. The main themes identified for patients were active coping, limited needs and limited knowledge and awareness about psychosocial support. The main themes for carers were passive coping and 'it's all about the patient'.

CONCLUSION

Mesothelioma patients do not seem to have high needs for psychosocial support, whereas carers do. However, knowledge about and awareness of psychosocial support is low among mesothelioma patients. The findings from this study should be used to adjust guidelines for psychosocial support in mesothelioma patients and their carers.

SARS-CoV-2 and Asbestos Exposure: Can Our Experience With Mesothelioma Patients Help Us Understand the Psychological Consequences of COVID-19 and Develop Interventions?

Since its emergence, the novel coronavirus disease of 2019 (COVID-19) has had enormous physical, social, and psychological impacts worldwide. The aim of this article was to identify elements of our knowledge on asbestos exposure and malignant mesothelioma (MM) that can provide insight into the psychological impact of the COVID-19 pandemic and be used to develop adequate interventions. Although the etiology of Covid-19 and MM differs, their psychological impacts have common characteristics: in both diseases, there is a feeling of being exposed through aerial contagion to an "invisible killer" without boundaries that can strike even the strongest individuals. In both cases, affected persons can experience personality dysfunction, anxiety, depression, and posttraumatic symptoms; helplessness, hopelessness, and projection of destructive thoughts onto external forces often emerge, while defense mechanisms such as denial, splitting, repression, and reduced emotional expression are used by individuals to contain their overwhelming anxieties. We believe that in both diseases, an integrated multidimensional intervention offered by hospitals and other public health services is the most effective approach to alleviating patients' and caregivers' psychological distress. In particular, we emphasize that in the context of both MM and COVID-19, Brief Psychoanalytic Group therapy can help patients and caregivers attribute meaning to the significant changes in their lives related to the experience of the disease and identify adaptive strategies and more realistic relational modalities to deal with what has happened to them. We also highlight the importance of developing a surveillance system that includes individual anamnestic evaluation of occupational risk factors for COVID-19 disease.
