Health-related quality of life in women with breast cancer in Korea: do sociodemographic characteristics and time since diagnosis make a difference?

Neuroscience on breaking bad news: Effects of physicians' response on patient emotion and trust

BACKGROUND

The outbreak of COVID-19, due to restrictions on patients' access to hospitals, makes patient mental health a severe problem to solve, especially for cancer patients. Delivering bad news has become one of the abilities that physicians need to improve. Former research has proposed communication strategies like SPIKES to respond to patients' emotions. However, existing strategies lack systematic and structural responses to different cues and concerns of patients.

OBJECTIVE

This study aims to investigate whether and how the response styles of information delivery, empathy, and authority affect patient emotions and trust in order to present a structural response system. Furthermore, we explore the correlation between strategies and EEG markers to moderate emotions and trust.

METHODS

This research selects different scenarios and strategies in the context of breast cancer and performs two experiments. First, we performed a behavioral experiment with 93 medical students and 15 breast cancer patients. Moreover, an EEG experiment with 53 students via video stimuli was conducted to explore the moderate function between strategies and emotions/trust. We use time-frequency analysis and the repeated measure ANOVA method to explore the association between strategy and EEG components. Furthermore, we perform a GLM method to investigate the relationship between EEG components and patient emotion and trust.

RESULTS

For the first time, this study proposes the strategy matrix. The response strategies NPIm and NRIa play important roles in this system. In behavioral experiments, information delivery, empathy, and authority strategy significantly affect emotions and trust. The scenario is significant as a moderator. In the EEG experiment, strategy NPIm has more correlation with parietal alpha power than other strategies, and parietal alpha power has a significant effect on emotions, which verifies that empathy-related cerebral activities affect emotions and trust.

CONCLUSION

According to the strategy matrix, physicians could apply strategy ERIa in most scenarios, and strategy NRIa in many scenarios, which means information provision is significant when it comes to responding to patients' cues and concerns. The most important strategy that physicians need to avoid is the authority strategy. Refusing to respond to patients' cues and concerns may cause their dislike. Moreover, through the EEG experiment, we verify that empathy affects emotions and trust from a neuroscience perspective and propose parietal alpha and frontal alpha as neuro-markers to moderate emotions and trust. Physicians could adjust strategies through these EEG markers.

Validity and reliability of the Health-Related Quality of Life Instrument with 8 Items (HINT-8) in Korean breast cancer patients

OBJECTIVE

This study evaluated the validity and reliability of the Health-Related Quality of Life Instrument with 8 Items (HINT-8) in postoperative breast cancer patients in South Korea.

METHODS

The study included 300 breast cancer patients visiting a tertiary hospital. We measured health-related quality of life (HRQoL) using the HINT-8, the 5-level EQ-5D version (EQ-5D-5L), and the Functional Assessment of Cancer Therapy-Breast (FACT-B). Discriminatory ability, known-group validity, and convergent validity were assessed. Reliability was evaluated with the Cohen kappa, weighted kappa, and intraclass correlation coefficient (ICC).

RESULTS

The EQ-5D-5L indexes (p<0.001) and EQ visual analogue scale (VAS) scores (p<0.001) were significantly higher in subjects with no problems in each item of the HINT-8 than in those with problems. The FACT-B total scores were also higher in subjects without problems on the HINT-8. Older age, lower education level, and comorbidities were associated with a lower HINT-8 index. The HINT-8 index was correlated with the EQ-5D-5L index and the EQ VAS, with correlation coefficients of 0.671 (p<0.001) and 0.577 (p<0.001), respectively. The correlation coefficients between the HINT-8 and the FACT-B ranged from 0.390 to 0.714. The ICC was 0.690 (95% confidence interval, 0.580-0.780).

CONCLUSION

The HINT-8 showed appropriate validity for capturing HRQoL in postoperative breast cancer patients.

Effect of persistent menopausal symptoms on the wellbeing of Japanese breast cancer survivors

While more women with breast cancer survive because of advances in cancer treatment including hormonal therapy, they are at a risk of menopausal symptoms, which can threaten their psychological wellbeing. We examined the effect of menopausal symptoms on women's psychological wellbeing during three different phases of breast cancer: short-term (0-1 years since diagnosis), medium-term (2-5 years), and long-term (more than 5 years). In this cross-sectional study, 425 survivors treated with hormonal therapy were recruited from a convenience sample in Japan and completed an anonymous self-administered questionnaire. Multiple regression analysis revealed that menopausal symptoms significantly contributed to psychological wellbeing in all phases. In long-term survivors, menopausal symptoms were significantly milder; however, the negative effect was prolonged. One in three to four survivors was suspected to have poor psychological wellbeing, irrespective of time. Although the effect of menopausal symptoms on psychological wellbeing has been described in short-term survivors, little is known about the long-term effect. This study examines the effect of menopausal symptoms on psychological wellbeing, thereby providing useful information regarding long-term quality of life.

Validity and reliability of EQ-5D-3L for breast cancer patients in Korea

Background

Recently, breast cancer incidence and prevalence has been increasing. Patients' health related quality of life is important considerations in the treatment of breast cancer. The EQ-5D-3L is one of most popular instruments to measure health related quality of life. This study was aimed to evaluate the validity and reliability of EQ-5D-3L in post-operative breast cancer patients from Korea.

Methods

A total of 827 patients visiting the ambulatory cancer center of 1 tertiary hospital after breast cancer surgery self-administered the EQ-5D-3L and Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B). We evaluated known-group validity using differences in the EQ-5D-3L index and EQ-VAS score according to demographic and clinical data. The discriminatory ability of the EQ-5D-3L was determined by comparing the mean FACT-B subscale scores between subjects with no problems and subjects with moderate or severe problems in each EQ-5D-3L dimension. Construct validity was evaluated by Pearson correlation coefficients among the EQ-5D-3L index and FACT-B subscales, respectively. Reliability was assessed in terms of test-retest reliability using Cohen’s kappa value and intra-class correlation coefficient (ICC).

Results

The EQ-5D-3L index and EQ-VAS score were higher in the educated, current radiotherapy and unmarried groups. The correlation of EQ-5D-3L index and subscales for the FACT-B was highest in physical well-being (r = 0.553) and lowest in social well-being (r = 0.199). For reliability, the Kappa values’ range was from 0.32 to 0.70, and ICCs of the EQ-5D-3L index and EQ-VAS scores were 0.70 and 0.48, respectively.

Conclusions

This study indicated that the EQ-5D-3L could be a valid health related quality of life instrument for postoperative breast cancer patients.

Re-examining definitions of spirituality in nursing research

AIM

To discuss the definition of spirituality and its limitations for nursing research. It proposes a definition that will capture more accurately the role of spirituality in health outcomes.

BACKGROUND

Studies have increasingly examined spirituality in nursing research as a coping mechanism attenuating the negative impact of traumatic stress on mental health. Existing definitions of spirituality in nursing research include elements of positive emotional states (meaning, purpose, general well-being) which confound mental health outcomes.

DATA SOURCES

Medline and CINAHL databases were searched from 2007-2011 for research articles examining spirituality definitions and measures used by nurse researchers.

DISCUSSION

An analysis of the definitions of spirituality in nursing research reveals inconsistencies and confounding mental health concepts. The authors propose defining spirituality in the context of religious involvement when conducting research, while using a broader definition of spirituality when providing spiritual care. They argue such definition provides a more appropriate method of measuring this concept in research aimed at evaluating mental health outcomes while preserving the currently used patient-defined definition of spirituality when providing spiritual care.

NURSING IMPLICATIONS

A consistent definition of spirituality in nursing research evaluating mental health outcomes, distinct from 'spiritual care' in a clinical setting, is essential to avoid tautological results that are meaningless. Appropriate definitions will enable nursing researchers to more clearly identify resilience mechanisms and improved health outcomes in those exposed to traumatic stress.

CONCLUSION

A definition of spirituality that focuses on religious involvement provides a more uniform and consistent measure for evaluating mental health outcomes in nursing research.
