Personality matters: relationship between personality characteristics, spirituality, demoralization, and perceived quality of life in a sample of end-of-life cancer patients

Demoralization: A concept analysis through a scoping review methodology

Background

Demoralization is a complex construct comprising of several clinical phenomena that has gained increasing interest in clinical practice and research; however, the concept needs to be sufficiently specified and clearly described. A concept analysis of demoralization is necessary to integrate previous research findings and establish the scientific foundation for future intervention research.

Aim

To analyze the concept of demoralization in terms of its antecedents, attributes, consequences, and empirical referents in health.

Methods

A concept analysis was performed using the Joanna Briggs Institute guidelines scoping review method and mapping information through the Walker and Avant concept analysis framework. Electronic databases, including PubMed, The Cochrane Library, Embase, PsycINFO, and Web of Science, were searched until September 15, 2024. The grey literature and other minor non-indexed publications were also reviewed.

Results

A total of 106 articles were included in the review. Antecedents included medical illness, symptom burden, low social support and coping difficulties. Attributes were identified as follows: dysphoria, disheartenment, helplessness, hopelessness, loss of meaning and purpose, and sense of failure. Consequences included poor quality of life, depression, anxiety, suicidal ideation and desire to die. The concept of demoralization was illustrated through a model case, one exhibiting borderline criterion and another displaying challenge.

Conclusion

This scoping review clarifies the clinical definition of demoralization, distinguishing it from common language usage and from other emotional symptoms frequently experienced by patients.

Implications for Practice

The identified attributes of demoralization play vital roles in health assessments and should guide nurses in providing appropriate patient care early on. Interventions should address the concept's antecedents and consequences.

Demoralization Syndrome in End-Of-Life Cancer Patients: A Qualitative Study

ObjectivesIn our previous study we analyzed the prevalence of demoralization in a sample of 235 end-of-life cancer patients using the Demoralization Scale (DS). The findings revealed that 50.2% of the participants reported experiencing a moderate level of demoralization. The main sub-dimensions observed from the original DS were Helplessness, Disheartenment, and Sense of Failure, which we have categorized as "Emotional Distress and Inability to Cope". The aim of this study was to qualitatively investigate the subjective experience of this factor among a group of terminal cancer patients.MethodA sample of 30 patients was interviewed using seven open-ended questions, divided into 3 categories: helplessness, disheartenment and sense of failure. Content analysis was performed.ResultsFaith and prayer, social support and preserving autonomy were the principal coping strategies used by the sample and have been classed as sources of hope. Sadness, anger, death anxiety, fear, and sickness were the most commonly expressed emotions. Faith, social support, autonomy, and fighting spirit were identified as the primary coping strategies.ConclusionsThis study allowed a better understanding of the patient's subjective experience of the demoralization sub-dimension. The deepening of the topic can increase personalized clinical interventions, according to the patient's needs.

The mediating effect of positive coping in the association between inner strength and demoralization in lung cancer chemotherapy patients

PURPOSE

To determine the influence of inner strength on demoralization in patients receiving chemotherapy for lung cancer and confirm the mediating role of positive coping style.

METHODS

This study was a cross-sectional study and included 210 patients from three general hospitals in China. A sociodemographic questionnaire, Inner Strength Scale, Simplified coping style subscale, and Demoralization Scale-II were applied. A structural equation model was conducted to estimate the hypothesis model of demoralization and explore the potential mediating mechanism.

RESULTS

Inner strength was positively correlated with positive coping style (P < 0.01). Inner strength, positive coping style, and demoralization were negatively correlated (P < 0.01). Furthermore, positive coping style mediated the relationship between inner strength and demoralization (β = - 0.269 (95% CI, - 0.415, - 0.159), P < 0.01), accounting for 37.41% of the total effect.

CONCLUSION

The results suggest a negative association between inner strength and demoralization in patients with lung cancer undergoing chemotherapy. Positive coping style as a mediating variable provided the impetus for the demoralization. Healthcare professionals might enhance the inner strength of lung cancer patients undergoing chemotherapy by carrying out targeted interventions and encouraging them to adopt positive coping strategies, which can reduce the level of demoralization and promote mental health.

Exploring the role of psychedelic-assisted therapy in enhancing spirituality and mystical experiences in patients with life-threatening illnesses: A systematic review

INTRODUCTION

Psychedelic-Assisted Therapy (PAT) is gaining traction as a novel approach to addressing the psychological and existential distress experienced by patients.

OBJECTIVES

This systematic review aimed to investigate the impact of PAT on spirituality, mystical experiences, and spiritual well-being (SpWB) in patients with life-threatening, incurable, or terminal illnesses.

METHODS

A comprehensive search was conducted across PubMed, Web of Science, and Cochrane databases to identify relevant studies published between 2013 and 2023. The study population comprised patients diagnosed with life-threatening illnesses. Various forms of PAT, encompassing both typical and atypical psychedelic substances, were considered as interventions, with no specific comparators outlined. The primary outcomes of interest included spirituality, mystical experience, and SpWB. Risk of bias assessment was performed using Cochrane's tools.

RESULTS

Six studies with a high risk of bias were included in the review, all conducted in the United States of America, involving 140 patients, the majority of whom had cancer (99 %). PAT, especially with psilocybin, demonstrated significant enhancements in spirituality, mystical experiences, and SpWB. Notably, SpWB showed improvements in all studies which assessed this spiritual outcome following PAT. Mystical experiences were correlated with improvements in spirituality in one study.

CONCLUSIONS

This systematic review underscores the potential of PAT to address unmet spiritual needs and enhance SpWB in patients with life-threatening illnesses. However, further research is needed to elucidate the mechanisms underlying these therapeutic effects. Rigorous evaluation of healthcare practitioners' role in guiding patients through PAT protocols is essential to ensure safe and effective implementation in palliative care settings.

Factors correlated with demoralization among cancer patients: A systematic review and meta-analysis

OBJECTIVES

Demoralization isa common psychological problem in cancer patients. The purpose of this study is to systematically evaluate the correlated factors of demoralization among cancer patients. We also summarized the available evidence, effect estimates, and the strength of statistical associations between demoralization and its associated factors.

METHODS

We systematically searched PubMed, Web of Science, CINAHL, Embase, the Cochrane Library, PsycINFO, and 2 electronic databases to identify studies published up to October 2023 with data on the correlates of demoralization. Two researchers independently reviewed references, extracted data, and assessed data quality. Meta-analysis was performed using R4.1.1 software.

RESULTS

Thirty-eight studies were included in this meta-analysis. For the most studied sociodemographic correlates, demoralization was negatively correlated with income (z = -0.29, 95% CI: -0.51, -0.02), education (z = - 0.11, 95% CI: - 0.16, -0.05), and age (z = -0.45, 95%CI: -0.75, -0.01). For the most studied clinical correlates, demoralization was positively correlated with symptom burden (z = 0.37, 95% CI: 0.22, 0.50) and negatively correlated with quality of life (z = -0.40, 95% CI: -0.54, -0.24). For the most studied psychosocial correlates, demoralization was negatively correlated with social support (z = -0.39, 95% CI: -0.51, -0.26) and positively correlated with anxiety (z = 0.65, 95% CI: 0.56, 0.73), depression (z = 0.61, 95% CI: 0.54, 0.67), and suicidal ideation (z = 0.48, 95% CI: 0.34, 0.60).

SIGNIFICANCE OF RESULTS

Demoralization showed either positive or negative associations with sociodemographic, clinical, and psychological variables. More research is needed to explore the underlying mechanisms to develop effective interventions. This review provides information on the factors associated with demoralization in cancer patients, which can be used to inform strategies for clinical care providers.

[The provision of assisted death in the context of the desire to anticipate death]

The entry into force of the Organic Law on the Regulation of Euthanasia in June 2021 obliges clinicians to reconsider their professional work, in the face of a new service that expands the limits of what was considered correct until then. This new service affects the entire healthcare system, but especially primary care professionals. Beyond the procedural and moral aspects, it is necessary to rethink the assessment of the patient who expresses a wish to die. In this review, we start with the relatively recent definition of the wish to hasten death (WTHD), its causes, epidemiology and differential diagnosis. Then, we examine the different mental frameworks found in the process of dying and the concept of a «good death». Finally, we analyse the paths that can lead to the provision of aid in dying within the framework of current legislation. The WTHD is specific to requests in case of «serious and advanced illness», not in other cases contemplated by the Law. When faced with a request to activate the Aid in Dying Prestation in the context of WTHD (that is, in the proximity of death), it becomes necessary to increase the patient's sense of control and begin to work on grief. Besides, in the face of an administrative process that will necessarily be long, adapting the therapeutic efforts and sedation should be considered as possible options. We understand that it is essential not to create false expectations for patients/families and not to overload healthcare professionals with administrative tasks that will be futile. It is difficult to balance these in the face of a request for a right to which the patient should always have access.

Fear of cancer recurrence in breast cancer survivors carrying a BRCA1 or 2 genetic mutation : a cross-sectional study

BACKGROUND

Fear of cancer recurrence (FCR) affects virtually all patients who have been treated for cancer, to varying degrees. Breast cancer survivors who carry a BRCA1 or BRCA2 gene mutation are at high risk of cancer recurrence. No study has yet assessed FCR specifically in this population.

OBJECTIVES

This cross-sectional study, conducted in women who were treated for breast cancer and carrying a BRCA1/2 mutation, aimed to: (1) assess the mean level of FCR and estimate the proportion of patients with clinical levels of FCR; (2) examine the relationships between FCR and selected psychological variables (e.g., avoidance, intolerance to uncertainty) and quality of life; (3) explore whether FCR levels vary as a function of the past preventive treatment received; and (4) to assess the associations between FCR and the presence of decisional conflict or regret regarding the various preventive options.

METHOD

Participants were recruited through an e-mail sent to an oncogenetic network mailing list (Réseau ROSE). Participants were asked to complete a battery of questionnaires online assessing FCR and other psychological and quality of life variables.

RESULTS

A total of 89 women completed the survey. Most participants had undergone a preventive mastectomy (62.9%) and a preventive salpingo-oophorectomy (75.3%) at the time of the study. The mean Fear of Cancer Recurrence Inventory-severity score was 16.8, which exceeds the clinical cut-off score of 13, and 70.8% of the participants showed a clinical level of FCR. FCR was significantly associated with higher levels of anxiety and depression, and higher avoidance and intolerance of uncertainty, but not with quality of life. No significant difference was observed on the total FCR score between women who had received preventive surgery (mastectomy and/or salpingo-oophorectomy) and those considering it, and those not considering it. The association was significant between higher FRC scores and greater decisional conflicts and regrets about choosing to undergo preventive surgery.

CONCLUSION

These data suggest that FCR is a significant problem for breast cancer survivors carrying a BRCA1/2 genetic mutation, even after undergoing a prophylactic surgery. This highlights the importance of providing these women with specific psychological intervention focusing on FCR.

The mediating effect of eHealth literacy on the relationship between health personality and quality of life in community-dwelling older adults

AIMS

To explore the relationship between health personality and quality of life among community-dwelling older adults and to examine the mediating effect of eHealth literacy on this relationship.

METHODS

A total of 413 community-dwelling older adults from central China were recruited from September 2022 to January 2023. A cross-sectional investigation was conducted using the Chinese versions of the Health Personality Assessment (HPA), eHealth Literacy Scale (eHEALS), and 12-item Short Form Health Survey (SF-12). Correlations between the three variables were examined by Pearson analysis, and mediation analysis was conducted to explore the direct, indirect, and total effects of the health personality on quality of life vis-à-vis eHealth literacy.

RESULTS

Health personality factors (including health neuroticism, health openness, and health conscientiousness), eHealth literacy, and quality of life are significantly correlated (P<0.05); eHealth literacy can play a significant mediating role in the relationship between health neuroticism (β= -0.256, 95 %CI: [-0.405, -0.119]), health openness (β = 0.488, 95 % CI: [0.343,0.652]), health conscientiousness (β= 0.489, 95 % CI: [0.354, 0.634]) and quality of life.

CONCLUSION

This study revealed that the effect of health personality factors (including health neuroticism, health openness, and health conscientiousness) on quality of life in older adults was mediated through eHealth literacy.

IMPACT

Individual personality is essential to understanding eHealth literacy and quality of life among community-dwelling older adults. It may be helpful to identify the health personality traits of older adults first, then implement targeted interventions accordingly to enhance eHealth literacy and ultimately improve quality of life.

Core and bridge symptoms of demoralization in Chinese female cancer patients: a network analysis

Objective

In this study, we explore the core and bridge symptoms of demoralization in female cancer patients in China, and provide a basis for precise psychological intervention among female cancer patients.

Methods

This study used a cross-sectional survey. Participants were recruited from three third-class hospitals in Jiangsu Province from June 2022 to June 2023 using the convenience sampling method. The severity of each symptom of demoralization was investigated in female cancer patients using the Demoralization Scale (DS). Network analysis was performed using the R language to identify core and bridge symptoms in the network and further explore some characteristic edge connections in the network.

Results

The network structure model of demoralization had strong accuracy and stability. In the network, the symptoms with the highest strength centrality were "Discouragement" (C3, strength=2.19), "No self-worth" (A3, strength=1.21), "Don't want to live" (A5, strength=1.20), "Hopeless" (D4, strength=0.81), and "Vulnerability" (B3, strength=0.74), respectively. The bridge strength analysis identified "Hopeless" (D4, bridge strength=0.92), "Discouragement" (C3, bridge strength=0.85), "No self-worth" (A3, bridge strength=0.75), "Poor spirits" (E2, bridge strength=0.71), and "Vulnerability" (B3, bridge strength=0.69) as the bridge symptoms. The strongest edge connections of all dimensions were "No self-worth" and "Worthless" (A3-E6, edge weighting=0.27), "Poor spirits" and "Loss of emotional control" (E2-D1, edge weighting=0.22), "Discouragement" and "Vulnerability" (C3-B3, edge weighting=0.14), and "Hopeless" and "No meaning of survival" (D4-A4, edge weighting=0.12).

Conclusion

"Discouragement (C3)", "No self-worth (A3)", "Hopeless (D4)", and "Vulnerability (B3)" are both core symptoms and bridge symptoms. These symptoms can not only trigger a patient's demoralization but also stimulate more severe symptom clusters through interactions. The early recognition of and intervention regarding these symptoms could be important for the prevention and treatment of demoralization among female cancer patients.

An Integrative Review of Measures of Spirituality in Experimental Studies of Psilocybin in Serious Illness Populations

Background: Psilocybin-assisted therapies (PAT) are reemerging as a treatment for complex distress often prompting mystical experiences, enhanced meaning, and spiritual wellbeing. We sought to investigate how measures of spirituality are employed in experimental studies of PAT conducted with seriously ill adults. Methods: We included experimental studies of psilocybin conducted with seriously ill adults, which employed measures that contained spirituality and mysticism concepts within their domains or subdomains. Included studies were peer-reviewed and published in English language (up to December 2021). Results: Seven articles met our inclusion criteria. A total of 12 unique instruments were identified. The most frequently used instruments were the Mystical Experience Questionnaire (MEQ30), the Functional Assessment of Chronic Illness Therapy-Spirituality (FACIT-Sp-12), and the Demoralization Scale (DS-I/II) (used in four studies each), followed by the Persisting Effects Questionnaire (PEQ) (used in three studies). Overall, studies did not consistently define and contextualize spirituality domains and subdomains studied. Conclusions: Despite well-recognized significance of spirituality in PAT, there was considerable heterogeneity in number and types of spirituality measures employed across studies. There also seemed a lack of attention to defining and operationalizing spirituality and its domains and subdomains. This is notable as spirituality and overlapping concepts (eg mystical experiences) contributes substantially to this body of research and patients' therapeutic outcomes. Towards developing more rigorous science of spirituality in PAT research, there is a critical need to evaluate and refine measures of spirituality to enhance their utility and replicability, limit participant burden, and better contextualize spirituality-related findings and outcomes.

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.

Status and influential factors of spiritual well-being in cancer patients with drug clinical trials: a cross-sectional study

PURPOSE

The purpose of this study was to investigate the spiritual well-being status of cancer patients in drug clinical trials and its influencing factors, and to provide theoretical support for the spiritual health intervention of clinical trial cancer patients.

METHODS

This cross-section study was conducted among 244 cancer patients in clinical trials. The Memorial Symptom Assessment Scale Short Form (MSAS-SF), Connor-Davidson Resilience Scale 10 (CD-RISC 10), and Functional Assessment of Chronic Illness Therapy-Spiritual (FACIT-SP-12) were used to measure symptom burden, psychological resilience, and spiritual well-being. The Multiple Linear Regression Model was used to determine the influencing factors of patients' spiritual health.

RESULTS

The overall spiritual health level of cancer patients with clinical trials was high (36.87 ± 11.0), and the spiritual health level was positively correlated with psychological resilience (r = 0.872, P < 0.001). Religious belief, nationality, treatment regimen, and resilience were independent risk factors for the spiritual health of cancer patients in clinical trials. Patients with religious beliefs (β = 0.097, P = 0.012), ethnic minorities (β = 0.087, P = 0.023), and high resilience scores (β = 0.874, P < 0.001) had higher levels of spiritual health. Patients who received single antineoplastic therapy (β =  - 0.079, P = 0.028) had lower levels of spiritual health.

CONCLUSION

Our study found that the spiritual health of cancer patients in clinical trials was at a high level, superior to cancer patients receiving conventional anti-tumor therapy. Religious belief, nationality, treatment regimen, and psychological resilience were the influential factors of spiritual health.

Neuroticism as a moderator of symptom-related distress and depression in 4 noncancer end-of-life populations

OBJECTIVES

Neuroticism is a significant predictor of adverse psychological outcomes in patients with cancer. Less is known about how this relationship manifests in those with noncancer illness at the end-of-life (EOL). The objective of this study was to examine the impact of neuroticism as a moderator of physical symptoms and development of depression in patients with amyotrophic lateral sclerosis (ALS), chronic obstructive pulmonary disease (COPD), end-stage renal disease (ESRD), and frailty in the last 6 months of life.

METHODS

We met this objective using secondary data collected in the Dignity and Distress across End-of-Life Populations study. The data included N = 404 patients with ALS (N = 101), COPD (N = 100), ESRD (N = 101), and frailty (N = 102) in the estimated last 6 months of life, with a range of illness-related symptoms, assessed longitudinally at 2 time points. We examined neuroticism as a moderator of illness-related symptoms at Time 1 (∼6 months before death) and depression at Time 2 (∼3 months before death) using ordinary least squares regression.

RESULTS

Results revealed that neuroticism significantly moderated the relationship between the following symptoms and depression measured 3 months later: drowsiness, fatigue, shortness of breath, wellbeing (ALS); drowsiness, trouble sleeping, will to live, activity (COPD); constipation (ESRD); and weakness and will to live (frailty).

SIGNIFICANCE OF RESULTS

These findings suggest that neuroticism represents a vulnerability factor that either attenuates or amplifies the relationship of specific illness and depressive symptoms in these noncancer illness groups at the EOL. Identifying those high in neuroticism may provide insight into patient populations that require special care at the EOL.

Demoralization and spirituality in oncology: an integrative systematic review

OBJECTIVE

To synthesize the scientific findings on demoralization and spirituality in the oncology context.

METHODS

This is an integrative systematic review, in line with the PRISMA 2020 guidelines, as proposed by Whittemore and Knalf (2005). The MEDLINE via PubMed, Scopus, Web of Science, APA PsycNet, CINAHL, Cochrane Library, EMBASE, and LILACS databases were searched without limitations regarding language or year of publication. The studies were screened for inclusion according to the predefined eligibility criteria. Data extraction and evidence quality assessment were performed.

RESULTS

Out of the 1587 articles evaluated, 10 studies were included in this review. In general, it was found that demoralization tends to increase with the proximity of death and seems to be inversely related to spirituality, with spiritual well-being being a protective factor against demoralization, while the non-fulfillment of spiritual needs is related to increased demoralization in people with cancer. Furthermore, even among caregivers of people with advanced cancer, demoralization seems to be associated, among other factors, with spiritual suffering. These results should be analyzed with caution, considering that the studies included in this review are all observational studies, which prevents establishing cause and effect relationships.

CONCLUSIONS

Demoralization tends to increase with growing frailty and the proximity of death in people with cancer, and it seems to be inversely related to spirituality, both in these patients and in their caregivers.

Personality trait associations with quality-of-life outcomes following bariatric surgery: a systematic review

BACKGROUND

Obesity can be a significant challenge to health and quality of life (QoL). Bariatric surgery assists with weight loss and may help improve QoL. However, not all patients benefit from surgery. Personality traits may be related to QoL outcomes after bariatric surgery, but these associations are unclear.

PURPOSE

This research reviews the published literature on the associations between personality and QoL among post-operative bariatric patients.

METHOD

Four databases (CINAHL Complete, Medline with Full Text, APA PsycINFO, and Scopus) were searched from inception until March 2022. Forward searching was conducted using Google Scholar, and backward reference citation searches were also performed.

RESULTS

Five studies met inclusion criteria yielding data from N = 441 post-bariatric patients including both pre/post and cross-sectional designs. Higher agreeableness was related to lower overall health-related QoL (HRQol) and gastric HRQol and positively associated with psychological HRQol. Higher emotional stability was positively related to overall HRQol. Higher impulsivity was negatively associated with mental HRQol and was unrelated to physical HRQol. Effects for the remaining traits were either mainly mixed or null.

CONCLUSION

Personality traits may be associated with HRQol outcomes. However, it is difficult to reliably discern the role of personality traits for HRQol and QoL outcomes given the methodological issues and few published studies. More rigorous research is needed to address these issues and clarify possible associations.

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.

Self-perceived burden predicts lower quality of life in advanced cancer patients: the mediating role of existential distress and anxiety

Background

Self-perceived burden (SPB) is an important predictor of quality of life (QoL) in patients with advanced cancer. However, the mechanism how SPB affects patients’ QoL remains unclear. This study aimed to examine the potential mediating roles of existential distress (ED) and anxiety in the relationship between SPB and QoL.

Methods

A multicenter cross-sectional study was conducted. 352 advanced cancer patients were recruited from three hospitals in southeast of China. The Self-perceived Burden Scale, the Existential Distress Scale, the Hospital Anxiety and Depression Scale, and the Quality-of-Life Concerns in the End of Life Questionnaire were adopted to collect data. Hayes’s bootstrapping method was used to analyze the data.

Results

SPB was negatively associated with QoL (P < 0.01). ED and anxiety partially mediated the relationship between SPB and QoL (P < 0.01). Moreover, ED had direct effects on anxiety, and sequentially QoL (P < 0.01). The serial multiple mediation model of SPB accounted for 73.25% of the variance in QoL in advanced cancer patients.

Conclusions

ED and anxiety are important mediating factors between SPB and QoL in advanced cancer patients. To improve patients’ QoL, comprehensive interventions for reducing anxiety and ED are highly recommended in clinical practices.

Different Electrophysiological Responses to Pain-Related Visual Stimuli Between Fibromyalgia and Chronic low Back Pain Women: A Pilot Case-Control Study

BACKGROUND

Fibromyalgia is a chronic pain syndrome which occurs in the absence of an organic damage, whom causes is still unclear. Aims of this pilot study were to investigate the neural correlates of fibromyalgia in response to pain-related visual stimuli and explore the psychological differences among fibromyalgia, chronic low back pain (CLBP) and healthy conditions.

METHODS

After a clinical assessment, electrophysiological responses to pain-related visual stimuli were recorded using a 256-Hydrocel Geodesic-Sensor-Net. Event-related potentials (ERPs), standardised low-resolution electromagnetic tomography (sLORETA), and psychological (Symptom Checklist-90-Revised) data were analysed for a total sample of 23 women (5 healthy volunteers, 12 fibromyalgia patients, 6 CLBP patients).

RESULTS

The main finding was that fibromyalgia women reported a different brain response to pain-related visual stimuli on the frontal montage compared to women with CLBP (p = .028). Moreover, fibromyalgia women showed an increased activity mainly on the hippocampus (p = .003) and the posterior cingulate cortex (p ≤ .001) in response to algic stimuli compared to not algic ones. Lastly, these women presented higher scores on the somatization (p = .002), obsession-compulsion (p = .045), depression (p = .043) and positive symptom distress (p = .023) dimensions compared to the healthy women.

CONCLUSIONS

These preliminary results suggest that although the painful symptoms are similar, the central elaboration of pain could be different between women with fibromyalgia and those with CLBP. Moreover, these findings provide preliminary evidences about the great alert and the central sensitivity to pain-related information regarding fibromyalgia patients.
