The Mediation and Suppression Effect of Demoralization in Breast Cancer Patients After Primary Therapy: A Structural Equation Model

Demoralization in cancer survivors: an updated systematic review and meta-analysis for quantitative studies

BACKGROUND

Demoralization can cause impairments across all life aspects of cancer patients. Cancer patients are also vulnerable during their survivorship. The purpose of this review is to examine the risk of demoralization and associated risk factors among cancer survivors who have completed their primary anti-cancer treatment or time since diagnosis ≥5 years without recurrence.

METHODS

We searched databases of PubMed, Cochrane, Embase, PsycINFO and ClinicalTrial.gov to identify eligible studies which reported the demoralization level among cancer survivors. A random-effect meta-analysis model was used for calculating mean demoralization level. Heterogeneity was evaluated by I2 statistics. Funnel plots and Egger's regression tests were performed for checking publication bias. We used one-study-removed method for sensitivity analysis. Subgroup analysis was also done to examine the difference of demoralization level between cancer types. Meta-regression was performed to reveal risk factors of demoralization.

RESULTS

A meta-analysis of 12 articles involving 2902 cancer survivors was conducted. The mean demoralization score among cancer survivors was 25.98 (95% CI: 23.53-28.43). Higher demoralization level was seen in participants with older age, higher female ratio, higher married/living together status ratio and higher patient health questionnaire-9 score. The literature review revealed correlations between demoralization and suicide risk, anxiety and quality of life. No consistent correlation between demoralization and post-traumatic stress symptoms could be seen.

CONCLUSIONS

High demoralization level is noticed among cancer survivors. Risks for females, elder patients or breast cancer survivors are identified. More longitudinal or interventional studies for cancer survivors' demoralization are expected in the future.

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.

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.

Information Needs of Patients With Breast Cancer Undergoing Treatment in Vietnam and Related Determinants

BACKGROUND

Patients with cancer who are not well informed often experience dissatisfaction with care, difficulty coping with their disease, and feelings of helplessness.

PURPOSE

This study was designed to investigate the information needs of women with breast cancer undergoing treatment in Vietnam and the determinants of these needs.

METHODS

One hundred thirty women undergoing chemotherapy for breast cancer in the National Cancer Hospital in Vietnam enrolled as volunteers in this cross-sectional descriptive correlational study. Self-perceived information needs, body functions, and disease symptoms were surveyed using the Toronto Informational Needs Questionnaire and the 23-item Breast Cancer Module of the European Organization for Research and Treatment of Cancer questionnaire, which consists of two (functional and symptom) subscales. Descriptive statistical analyses included t test, analysis of variance, Pearson correlation, and multiple linear regression.

RESULTS

The results revealed participants had high information needs and a negative future perspective. The highest information needs related to potential for recurrence, interpretation of blood test results, treatment side effects, and diet. Future perspective, income level, and educational level were identified as determinants of information needs, explaining 28.2% of the variance in the need for breast cancer information.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

This study was the first to use a validated questionnaire to assess information needs in women with breast cancer in Vietnam. Healthcare professionals may refer to the findings of this study when designing and delivering health education programs designed to meet the self-perceived information needs of women with breast cancer in Vietnam.

Understanding factors influencing demoralization among cancer patients based on the bio-psycho-social model: A systematic review

OBJECTIVE

Demoralization is a prevalent psychological problem among cancer patients and reflects a sense of subjective incompetence. This systematic review aims to identify factors influencing demoralization among cancer patients.

METHODS

Eleven databases were systematically searched from database inception to 31 December 2020. Google Scholar and relevant reference lists were supplementarily searched. Studies reporting demoralization measured by Demoralization Scale and its influencing factors among cancer patients were included. A qualitative synthesis was conducted owing to the heterogeneity of the study outcome.

RESULTS

A total of 49 studies involving 10,712 participants were included in this review. The results showed substantial effect size variation, but the psychological factors showed the strongest magnitude of association. Among the biological factors, the number of physical symptoms (mean r values [rs]: 0.331) was associated with increased demoralization. Among the psychological factors, negative psychological factors include hopelessness (mean rs: 0.633), desire for death (mean rs: 0.620), dignity-related distress (mean rs: 0.595), depression (mean rs: 0.593), anxiety (mean rs: 0.589), psychological distress (mean rs: 0.465), and suicidal ideation (mean rs: 0.460) were related to increased demoralization; whereas positive psychological factors including hope (mean rs: -0.565), attachment security (mean rs: -0.530), and sense of coherence (mean rs: -0.453) were related to decreased demoralization. Among the social factors, social support (mean rs: -0.330) was negatively related to demoralization, and the demographic factors were still controversial. Quality of life was considered to be at the intersection of biopsychosocial factors and negatively associated with demoralization (mean rs: -0.599).

CONCLUSIONS

Demoralization is a consequence of the interaction of physical, psychological, and social factors among cancer patients. Factors with a significant effect should not be overlooked when designing an intervention to reduce demoralization. It is necessary to distinguish demoralization from other negative psychological states and further explore positive psychological factors influencing demoralization among cancer patients.

Demoralization and Its Association with Quality of Life, Sleep Quality, Spiritual Interests, and Suicide Risk in Breast Cancer Inpatients: A Cross-Sectional Study

With decreasing mortality, the quality of life, spiritual needs, and mental health of breast cancer patients have become increasingly important. Demoralization is a poor prognostic factor for cancer patients. The extent of demoralization in breast cancer patients and its association with these factors remains unclear. This cross-sectional study was conducted at a Taiwanese medical center. We enrolled 121 participants (34 with high demoralization and 87 with low demoralization, as per the Mandarin Version of Demoralization Scale). High demoralization was associated with reduced quality of life, sleep quality, and spiritual interests. Multivariate analyses revealed that the scores of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire ≥ 62.5 (OR = 0.21, p = 0.002) and Spiritual Interests Related to Illness Tool Chinese Version ≥ 3.66 (OR = 0.11, p < 0.001) were associated with low demoralization. Demoralized patients with depression had a poorer quality of life and sleep quality. Although not statistically significant, depressed and demoralized participants were at a higher risk of suicide. Cancer patients with both depression and demoralization had the worst prognosis. Breast cancer patients exhibited demoralization when they had unmet bio-psycho-social-spiritual needs. An early assessment of demoralization may improve holistic healthcare for breast cancer patients.

Exploring Meaning of Life in Women With Breast Cancer in Taiwan: A Phenomenological Study

BACKGROUND

Globally, breast cancer is the most common cancer type in terms of incidence for women. Women with breast cancer endure higher levels of psychological distress than other types of cancer because many lose their identity as a woman, which is an additional characteristic of their psychological distress. Research using phenomenology to explore "the meaning of life" is rare among women with breast cancer.

PURPOSE

The purpose of this study was to explore the perspectives of women with breast cancer on "the meaning of life."

METHODS

A phenomenological approach was used. Twenty-six women living with breast cancer drawn from a cancer treatment hospital in Taiwan participated in this study. A semistructured interview was utilized to collect the data, and Colaizzi's seven steps were used to analyze the data.

RESULTS

Four themes emerged: (a) value of overcoming suffering, (b) value of reciprocal love, (c) value of self-transcendence, and (d) value of spiritual comfort. This means that the participants defined "the meaning of life" through the lens of suffering from cancer, reciprocal love from their families and friends, uncovering and discovering creative pathways that transformed their pain while searching for the value of their existence, and seeking spiritual guidance from religion.

CONCLUSIONS

The participants identified the most pivotal aspect of healing as transforming their pain and accepting value for their suffering. They acknowledged they could not change the fact that they had cancer, but they could learn to accept it as part of their lived experience. Healthcare professionals may use these four themes at a clinically appropriate time on women's journeys toward healing to inspire women with breast cancer to process their own unique "meaning of life."

Correlations among the Mandarin Voice Handicap Index, its shortened version, and the Voice-Related Quality of Life Measure for laryngectomees

BACKGROUND

The Voice Handicap Index (VHI) and the Voice-Related Quality of Life Measure (V-RQOL) are seldom administered to alaryngeal patients who use pneumatic artificial larynx (PAL) and esophageal speech (ES). As such, the specificity of VHI and 10-item VHI (VHI-10) for assessing voice-related changes in such patients is unclear. Accordingly, this study investigated the correlation between scores on the VHI, its shortened version (VHI-10), and the V-RQOL for Mandarin-speaking laryngectomees using PAL and ES, with the aim of establishing which of these instruments is suited to such patients.

METHODS

The participants comprised 126 PAL and 26 ES patients from Taiwan who completed the Mandarin VHI and V-RQOL. Fifty-two of these alaryngeal participants then completed both those instruments a second time, between 8 and 64 days later.

RESULTS

One item appearing in both the Mandarin long-form VHI and the VHI-10 was excluded because more than half the participants left it unanswered. The correlation of scores on the remaining 29 items on the former with the nine on the latter was high ( r = 0.968), while that between the former and V-RQOL scores was moderate ( r = -0.569), as was the correlation between short-form VHI and Mandarin V-RQOL scores ( r = -0.582). Structural equation modeling was then used as the basis for simplifying the Mandarin long-form VHI into a new 10-item VHI specifically for alaryngeal Mandarin speakers (MA-VHI-10), to eliminate the scoring effect of the original VHI's and VHI-10's work-related item. MA-VHI-10 scores were highly correlated with those on the Mandarin long-form VHI ( r = 0.983).

CONCLUSION

The Mandarin versions of long-form VHI, short-form VHI, and MA-VHI-10 are interchangeable for a Mandarin-speaking alaryngeal population. However, neither of the former two instruments should be substituted for the V-RQOL.

Demoralization level fluctuated at various time frame of radiotherapy for patients with different cancers: a longitudinal observational study

Background

Demoralization is a psychological response that is frequently observed in patients with cancer or advanced diseases. It is affected by national characteristics, culture, disease characteristics and general conditions of the patient such as individual cultural features, nature of stress, personal expression preferences and social behavior. Compared with the results of previous studies on demoralization syndrome, patients with cancer in Taiwan exhibit a higher prevalence of demoralization. We aimed to investigate the prevalence of high demoralization and the changes in the level of demoralization in cancer patients during radiotherapy to explore the associated factors and the contributing factors to the high level of demoralization.

Methods

We used the Demoralization Scale-Mandarin Version to evaluate the demoralization level at six-time points in patients admitted for radiotherapy in a 3-month observational period. 101 patients allocated to three groups by cancer region completed the study. We applied the generalized estimating equation (GEE) to analyze the changes in the demoralization level among the three groups. The variables associated with the changes in the demoralization level were also investigated.

Results

In the analysis using univariate GEE, only patients in the chest and breast group exhibited significant changes at two different time points. The results obtained using multivariate GEE revealed that sociodemographic variables, stage of disease and use of surgery or chemotherapy had no impact on the changes in demoralization across three months.

Conclusion

The demoralization level certainly fluctuated in an extremely high range. The higher prevalence of demoralized patients may indicate that if medical staff neglect the importance of demoralization, demoralized patients with cancer may not receive appropriate care.

Psychological Well-Being Increment as Post-Traumatic Growth in Women with Breast Cancer: A Controlled Comparison Design Using Propensity Score Matching

The aim of this study was to confirm post-traumatic growth with respect to the psychological well-being of women with breast cancer compared to women without disease. Propensity score was used to match the two groups according to age, religious beliefs, education level, monthly income, and marital status. A psychological well-being scale with six factors was used, including positive relations with others (PR), autonomy (AU), environmental mastery (EM), personal growth (PG), purpose in life (PL), and self-acceptance (SA). A total 178 women with vs. 178 women without breast cancer were compared by matching with propensity scores, using factorial invariance tests to reduce measurement errors. The results showed that women with breast cancer had significantly higher psychological well-being for all the six factors (Δχ2 = 37.37, p < 0.001) and higher variability in terms of PR, AU, and PL than women without breast cancer (Δχ2 = 45.94, p < 0.001). Furthermore, women with breast cancer exhibited a significantly higher association between PG and PL and a significantly lower association between PG and EM than women without breast cancer (Δχ2 = 44.49, p < 0.001). This implies that psychological well-being could assess broader and more subtle post-traumatic growth in women with breast cancer and that growth was more associated with internal life value than with external environmental control.
