Perceived relatedness, death acceptance, and demoralization in patients with cancer

Prevalence, Associated Factors and Adverse Outcomes of Demoralization in Cancer Patients: A Decade of Systematic Review

Demoralization has been extensively studied in oncology and palliative care settings, and is characterized by a loss of meaning and purpose in life, a sense of powerlessness over life events, and a sense of helplessness. The objective of this systematic review is to synthesize the prevalence, associated factors, and adverse outcomes of demoralization in cancer patients by reviewing the literature of the last decade. Seven databases (PubMed, PsycINFO, Embase, Web of Science, Medline, CINAHL and Cochrane Library databases) were systematically searched from January 2012 to June 2022. Roughly speaking, the prevalence of demoralization in cancer patients ranges from 13.50% to 49.4%. A total of 45 factors are associated with demoralization, of which psychological factors have been studied more frequently in the last decade. There are nine outcomes related to demoralization, with the strongest evidence for the correlation between demoralization and suicidal ideation. The study emphasizes the complexity of factors associated with demoralization in cancer patients. There appears to be a intersection between the constructs of demoralization and depression, anxiety, and suicidal ideation, which may explain the correlation between them.

Clinical utility of demoralization: A systematic review of the literature

Demoralization is a complex clinical phenomenon which has raised a growing interest in clinical and research realms. The present systematic review of the literature aimed at (1) updating on demoralization prevalence in different populations, (2) identifying the instruments more largely used to assess demoralization, and (3) verifying whether new tools of assessment have been proposed. PubMed and Web of Science were searched from inception to April 2022. Search terms were: demoralization/demoralized/demoralizing/demoralised/demoralising. PRISMA guidelines were followed. GRADE rating system was used. A total of 188 papers were included. Demoralization appeared to be a distinctive psychological state common in medical, psychiatric, and non-clinical settings, thus not limited to life-threatening diseases. Diagnostic Criteria for Psychosomatic Research (DCPR) and Demoralization Scale (DS) are the most commonly used tools to assess it. DCPR allow to diagnose demoralization as a manifestation of dealing with chronic stress. DS captures dimensionally a psychological distress related to end of life. Demoralization is associated with clinical features encompassing allostatic overload, quality of life, wellbeing/euthymia. Implications on health outcomes and treatment are discussed. Demoralization warrants careful consideration in clinical contexts through valid assessment procedures. DCPR are recommended to diagnose it, DS can be helpful to capture clinical details.

Psychedelic/entactogen‐assisted therapy for treatment of anxiety, depression and existential distress in adult palliative care

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To assess the benefits and harms of psychedelic/entactogen‐assisted therapy compared to placebo or active comparators (e.g. antidepressants) for treatment of anxiety, depression, and existential distress in adult palliative care.

Mental state of demoralisation across diverse clinical settings: A systematic review, meta-analysis and proposal for its use as a 'specifier' in mental illness

OBJECTIVE

Demoralisation is a state of poor coping characterised by low morale, hopelessness, subjective incompetence, and loss of meaning and purpose in life. While studied extensively in oncology and palliative care, there has been recent exploration in broader medical and mental health settings. The aim was to investigate the prevalence of demoralisation and associated sociodemographic and psychological factors across these clinical settings.

METHOD

Six electronic databases were used to locate articles from January 2014 to March 2020. A pre-publication update of non-oncology populations was completed in September 2021. The review has been reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Pooled prevalence of demoralisation was determined through % prevalence and mean demoralisation score; this was synthesised through meta-analysis of single means to determine pooled mean prevalence of Demoralisation Scale scores using the 'R' statistical software.

RESULTS

Demoralisation has been examined in 52 studies (n = 11,670) and found to be prevalent in 24-35% of oncology and non-oncology, including mental health, populations. The mean score on the Demoralisation Scale was 24.3 (95% confidence interval, CI = [21.3, 27.3]). There was evidence of divergent validity in addition to significant comorbidity between depression, demoralisation and suicidal ideation. Burdensome physical symptoms, and psychological and demographic factors are strongly correlated with demoralisation.

CONCLUSION

There remains a need to recognise demoralisation in various clinical and cultural settings and to strongly consider its inclusion as a 'specifier' within formal nosological systems for adjustment and depressive disorders. This is important to initiate targeted interventions and prevent significant morbidity.

Associations between a sense of connection and existential and psychosocial outcomes in gynecologic and breast cancer survivors

BACKGROUND

A cancer diagnosis may lead to existential despair but potentially also to perceived inner growth. This growth may be fostered through meaningful connections with others. We sought to describe existential and related psychosocial outcomes and their association with a sense of connection with others in individuals with gynecological and breast cancers.

METHODS

We used cross-sectional data from two ongoing cohort studies of gynecologic (N = 236) and breast (N = 62) cancer survivors at the University of Minnesota. We summarized self-reported post-traumatic growth (PTG), sense of meaning, peace, spirituality, hopelessness, loneliness, and three exploratory measures of sense of connections with others, and used multivariate linear regression models to describe the associations between them.

RESULTS

Hope, sense of meaning, peace, and spirituality were generally high among participants, but PTG and loneliness scores varied more. Sense of connection with others was consistently associated with greater PTG and decreased loneliness with medium effect sizes: for example having positive interactions with most/all versus nobody on one's medical team, PTG (coefficient 10.49, 95% CI: 4.10, 16.87, Cohen's D 0.44); loneliness (coefficient - 0.85, 95% CI: - 1.36, - 0.34, Cohen's D 0.43). Those who knew someone in a similar life situation felt a strong sense of connection with such a person; however, 28% of participants had not met anyone in a similar situation.

CONCLUSIONS

There may be untapped opportunities to nurture beneficial existential outcomes in cancer survivors. Potential interventions include connecting survivors with one another and creating opportunities for more authentic patient-provider relationships, for example, within palliative care.

Reflecting on meaning in an existential-reorientation group psychotherapy approach for cancer patients: A qualitative thematic analysis

OBJECTIVE

The objectives of this study were to evaluate, in the Italian cultural context, breast cancer patients' main meaning themes related to the experience of the disease, on the one side, and to be part of an existentially oriented group intervention, on the other.

METHOD

A short reorientation-existential (RET) group intervention, structured by using some tools and background from cognitive analytic therapy (CAT) and based on the meaning-centered psychotherapy (MCP) existential framework, was delivered to 29 breast cancer patients. The sessions were audio-recorded and transcribed verbatim, with the narratives from reflective exercises (meaning of the journey cancer, meaning of the journey of intervention) uploaded to computer software NVivo 11. Analysis of the transcripts emerged from reflective exercises on the personal meaning of cancer and the letters of meaning (goodbye letter) written by the patients to express the meaning of their experience in the group was conducted through the interpretative phenomenological analysis (IPA) framework.

RESULTS

Four superordinate themes were identified in the exercise meaning of the experience of cancer, namely "sense of stigma and loneliness (the foreigner)," "guilt (unjust guilt and anticipatory guilt)," "reconsidering one's own life and nostalgia," and "rebirth (a new life, life after life)." Three superordinate themes were found in the meaning of the group experience in the letters, namely "togetherness and gratitude," "legacy," and "acceptance."

SIGNIFICANCE OF RESULTS

The study confirmed that a short group intervention, based on the existentially oriented framework and delivered in a public clinical healthcare setting, was enriched by focusing on the personal meaning of cancer. Some themes, such as loneliness, nostalgia, and rebirth, emerged during reflection giving, in written letters to participants, the sense of the group therapeutic experience.

Norm Values and Psychometric Properties of the 24-Item Demoralization Scale (DS-I) in a Representative Sample of the German General Population

Purpose: The Demoralization scale (DS-I) is a validated and frequently used instrument to assess existential distress in patients with cancer and other severe medical illness. The purpose of this study was to provide normative values derived from a representative German general population sample and to analyze the correlational structure of the DS-I.

Methods: A representative sample of the adult German general population completed the DS-I (24 Items), the Emotion Thermometers (ET) measuring distress, anxiety, depression, anger, need for help, and the Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-fatigue).

Results: The sample consists of N = 2,407 adults (mean age = 49.8; range = 18–94 years), 55.7% women). The percentages of participants above the DS-I cutoff (≥30) was 13.5%. The mean scores of the DS-I dimensions were as follows: (1) loss of meaning and purpose: M = 2.78 SD = 4.49; (2) disheartenment: M = 3.19 SD = 4.03; (3) dysphoria M = 4.51 SD = 3.20; (4) sense of failure: M = 6.24 SD = 3.40; and for the DS-I total score: M = 16.72 SD = 12.74. Women reported significantly higher levels of demoralization than men, with effect sizes between d = 0.09 (Loss of Meaning) and d = 0.21 (Dysphoria). Age was not associated with demoralization in our sample. DS-I reliability was excellent (α = 0.94) and DS-I subscales were interrelated (r between 0.31 and 0.87) and significantly correlated with ET, especially depression, anxiety, and need for help and fatigue (r between 0.14 and 0.69).

Conclusions: In order to use the DS-I as a screening tool in clinical practice and research the normative values are essential for comparing the symptom burden of groups of patients within the health care system to the general population. Age and sex differences between groups of patients can be accounted for using the presented normative scores of the DS-I.

Existential distress in patients with advanced cancer and their caregivers: study protocol of a longitudinal cohort study

INTRODUCTION

At the end of life, patients with advanced cancer and their informal caregivers may confront multiple existential concerns. Despite the strong potential to alleviate existential distress through psychosocial interventions, existential distress and its impact on healthcare outcomes have not yet been studied systematically. We aim to investigate the frequency, longitudinal trajectory and predictive impact of existential distress on end-of-life outcomes. We further aim to determine patients' and caregivers' specific need for and utilisation of psychosocial support for existential distress.

METHODS

This longitudinal cohort study will consecutively recruit 500 patients with advanced cancer and 500 caregivers from oncological outpatient and inpatient clinics. Participants will complete self-report questionnaires (sociodemographic and disease-related characteristics, existential distress, end-of-life outcomes, resources and support needs) at five points of assessment (at baseline and after 3, 6, 9 and 12 months). At baseline and 6-month follow-up, we will conduct structured diagnostic interviews to assess mental disorders. Statistical analyses will include descriptive statistics to determine the prevalence of existential distress, mental disorders and end-of-life outcomes; multiple linear and logistic regression analyses to calculate the predictive impact of existential distress on end-of-life outcomes; and growth mixture models to analyse longitudinal trajectories of existential distress.

DISCUSSION

This study will provide comprehensive knowledge about patients' and caregivers' existential concerns. The longitudinal empirical data will allow for conclusions concerning the frequency and course of existential distress throughout 1 year. This important extension of existing cross-sectional research will contribute to further develop targeted psychosocial interventions. Profiles of existential distress may be applied by clinicians from multiple professions and help to address existential concerns effectively.

ETHICS AND DISSEMINATION

The study was approved by the institutional research ethics committee (reference number LPEK-0177). Results will be presented at scientific conferences and published in peer-reviewed journals. Other forms of dissemination will include sharing results on the psychometric properties of the structured demoralisation interview with international research groups and communication with healthcare professionals providing psychosocial treatment for patients and caregivers. Following scientific standards, our progress will be regularly updated on ClinicalTrials.gov.

The role of attachment avoidance: A longitudinal mediation model predicting existential distress in patients with advanced cancer

OBJECTIVE

Although a protective effect of reliable interpersonal relationships on existential distress has been established, evidence remains inconclusive for attachment insecurity as an underlying factor of persistent psychological distress. We tested a longitudinal model hypothesizing attachment avoidance as a mediator of high demoralization and anxiety over time.

METHODS

We studied 206 patients with advanced cancer (mean age = 59.6, 61% female) participating in an intervention trial. Patients completed self-report measures for demoralization, anxiety, perceived relatedness, attachment insecurity, and death anxiety. Our mediated path model included perceived relatedness and death anxiety at baseline as predictors, attachment avoidance at baseline as mediator, and demoralization and anxiety at 6-month follow-up (N = 125) as outcomes.

RESULTS

Attachment avoidance partially mediated the relationship between death anxiety and demoralization (β = 0.07, 95% CI 0.02-0.12) and anxiety (β = 0.05, 95% CI 0.001-0.10). Findings for perceived relatedness were less conclusive. Its indirect effects through attachment avoidance were significant for both outcomes (demoralization: β = -0.07, 95% CI -0.13 to -0.02, anxiety: β = -0.05, 95% CI -0.11 to -0.003).

CONCLUSIONS

Due to its trait-like quality, attachment avoidance may play a less central role in explaining the course of existential distress over time than previous research indicated. Addressing change-sensitive relational concerns in psychosocial interventions may be more effective to alleviate existential distress.

Traditional Chinese Medicine in Cancer Care: An Overview of 5834 Randomized Controlled Trials Published in Chinese

BACKGROUND

Traditional Chinese medicine (TCM) is widely integrated into cancer care in China. An overview in 2011 identified 2384 randomized and non-randomized controlled trials (RCTs, non-RCTs) on TCM for cancer published in the Chinese literature. This article summarizes updated evidence of RCTs on TCM for cancer care.

METHODS

We searched 4 main Chinese databases: China National Knowledge Infrastructure, Chinese Scientific Journal Database, SinoMed, and Wanfang. RCTs on TCM used in cancer care were analyzed in this bibliometric study.

RESULTS

Of 5834 RCTs (477 157 cancer patients), only 62 RCTs were indexed in MEDLINE. The top 3 cancers treated were lung, stomach, and breast cancer. About 4752 RCTs (81.45%) tested TCM combined with conventional treatment, and 1082 RCTs (18.55%) used TCM alone for treating symptoms and side-effects. Herbal medicine was the most frequently used TCM modality (5087 RCTs; 87.20%). The most frequently reported outcome was symptom improvement (3712 RCTs; 63.63%) followed by quality of life (2725 RCTs; 46.71%), and biomarkers (2384 RCTs; 40.86%). The majority of RCTs (4051; 69.44%) concluded there were beneficial effects using either TCM alone or TCM plus conventional treatment compared with conventional treatment.

CONCLUSION

Substantial randomized trials demonstrated different types/stages of cancer were treated by various TCM modalities, alone or in combination with conventional medicine. Further evaluation on the effects and safety of TCM modalities focusing on outcomes such as quality of life is required.
