Gender differences in factors associated with body weight misperception.

OBJECTIVE: Gender analysis in health research is important to strengthen our health system. The current study aimed to explore factors related to body weight misperception in a national sample of the general Korean population. DESIGN: Cross-sectional study. SETTING: South Korea, general population. PARTICIPANTS: 12,900 adults enrolled from the Seventh Korea National Health and Nutrition Examination Survey (2016-2018). RESULTS: Disadvantageous socio-economic status was considered a predictor of participants' misperceptions of themselves as being of a healthy weight despite being overweight and as underweight despite being of a healthy weight, mainly in men. Favourable socio-economic status was considered a predictor of participants' misperceptions of themselves as being of a healthy weight despite being underweight and as overweight despite being of a healthy weight, mainly in women. Living in an urban area was an independent predictor of men's misperception of themselves as being of a healthy weight despite being overweight and women's misperception of themselves as being underweight despite being of a healthy weight. Physical inactivity was a predictor of most misperceptions in women. Psychological variables, such as stress and depression, were not significant predictors of misperception. CONCLUSIONS: The current study highlighted the gender differences in factors related to body weight misperception. These differences suggested that more sophisticated policies should be formulated to identify solutions to health problems related to body weight.

Factors Related to the Behavior of People Who Have Never Used the Internet for Voluntary Reasons: Cross-Sectional Survey Study.

BACKGROUND: If there are people who do not want to use the internet despite having the circumstances and conditions for using it, another policy consideration will be needed. OBJECTIVE: The purpose of this study was to explore the factors related to the behavior of people who do not voluntarily use the internet. METHODS: A cross-sectional survey was conducted in 2018. It used a proportional quota random sampling design to select a representative sample of Koreans. Accordingly, 6150 participants were included in the study. Multiple logistic regression methods were used to explore the predicting factors of the act of voluntarily not using the internet. RESULTS: Age, education level, bonding and bridging social capitals, and daily life satisfaction for health status were found to be factors related to the behavior of not voluntarily using the internet. However, gender, household income, occupation, family size, and community type were not related to voluntary nonuse of the internet. CONCLUSIONS: It was found that sociodemographic factors, such as age and education level, which are difficult to modify, along with psychosocial factors located deeper than the visible living conditions, such as social capital and life satisfaction, are involved in voluntary internet nonuse. These results also suggest that it is not desirable to proceed with policies related to information and communications technology on a separate track, but rather that they should be comprehensively approached with other social policies that design various social interventions in order to enhance equity within the society.

The Fear of Cancer from the Standpoint of Oneself, the Opposite Sex and the Fear of Side Effects of Cancer Treatment.

PURPOSE: It is important to understand the differences between men and women when it comes to attitudes and risk perception toward disease. This study aimed to explore the fear of cancer from the standpoint of themselves and the opposite sex by cancer type. MATERIALS AND METHODS: A cross-sectional survey with a representative sample was conducted. RESULTS: The least and the most feared cancers in men were thyroid cancer and lung cancer, respectively. When men assumed the perspective of women, the least and the most feared cancer were thyroid cancer and stomach cancer, respectively. The least and the most feared cancers in women were thyroid cancer and stomach cancer, respectively. When women assumed the perspective of men, the least and the most feared cancer were prostate cancer and lung cancer, respectively. When both men and women assume the perspective of the opposite sex, the fear of sex-specific cancer was relatively low compared to the actual responses of both men and women. The top six of the most feared side effects of cancer treatment were pain, psychological problems, general weakness, digestive dysfunction, fatigue, and appearance change. These were the same between men and women. CONCLUSION: Health care providers and caregivers in the family should provide care with more attention to the differences in thoughts about cancer between men and women. Health care providers should provide care with more attention to the differences in these problems between men and women.

Gap between Perceived eHealth Literacy and Ability to Use Online Cancer-Related Information.

BACKGROUND: The effective evaluation of health information available online is an important skill. However, consumers' self-perceptions of their eHealth literacy levels do not reflect their actual capabilities. The goal of this experimental study of online search behavior is to identify differences between self-perceived eHealth literacy and actual ability to use the accuracy of cancer information available online. METHODS: Thirty-one adults participated in the study conducted on July 15 and 16, 2017. We first measured perceived eHealth literacy and then asked participants 5 questions concerning cancer. Bandicam (v3.3.0) and BrowsingHistoryView were used to record search behavior and uniform resource locators, respectively. A Mann-Whitney U test and Fisher's exact test were performed. RESULTS: The results showed that participants most frequently searched for cancer information on blogs and café websites. Regarding search behavior, those who perceived higher knowledge in available resources tended to solve the given problem with significantly smaller number of webpages to answer a weight management question. Participants who perceived higher knowledge in helpfulness of information tended to use significantly smaller number of webpages to answer questions on red ginseng's preventive effects on caner and weight management. However, there was no proof that the high eHealth literacy group had significantly higher rates of correct answers than the low eHealth literacy group. Further, regarding cancer screening, the rates of correct answers were low for groups who considered their ability higher to find helpful resources and perceived higher knowledge in helpfulness of information. CONCLUSION: There is a gap between perceived eHealth literacy and the actual ability to use online cancer-related information. To fundamentally improve eHealth literacy, it is important to evaluate the actual abilities concerning each eHealth literacy component and to provide customized education.

Socioeconomic Burden of Cancer in Korea from 2011 to 2015.

PURPOSE: Though the socioeconomic burden of cancer on patients is increasing in South Korea, there is little research regarding the type of cancer that incurs the highest costs. This study analyzed the socioeconomic burden on cancer patients from 2011 to 2015 according to sex and age. MATERIALS AND METHODS: A prevalence-based approach was applied utilizing claim data of the National Health Insurance Service in Korea to estimate the socioeconomic burden of cancer on patients. Patients who received treatment for cancer from 2011 to 2015 were the study subjects. The total socioeconomic burden of their disease and treatment was divided into direct and indirect costs. RESULTS: There was an increase of 50.7% for 5 years, from 821,525 to 1,237,739 cancer patients. The cancer costs for men and women increased $8,268.4 million to $9,469.7 million and $3,626.5 million to $4,475.6 million, respectively. Furthermore, the 50-59-year-old age group accounted for a large portion of the total disease cost. Liver, lung, stomach, and colorectal cancers created the heaviest economic burdens on patients. CONCLUSION: Overall, this study indicates new policies for cancer prevention, early detection, and post-cancer treatment management are necessary to help limit the costs associatedwith cancer, especially in the elderly, and provides a foundation for establishing cancer-related health care policies, particularly by defining those cancers with heavier disease burdens.

Burnout Among oncologists in the Republic of Korea: A nationwide survey.

PURPOSE: Burnout in oncologists negatively impacts patient care and health care system, as it is associated with poor patient satisfaction, medical errors, leaving current practice, and/or early retirement. Because the quality of life of oncologists is influenced by various factors and ultimately affects the patient's treatment and medical system, we aimed to investigate burnout among oncologists and to identify factors affecting burnout. MATERIALS AND METHODS: A total of 130 oncologists recruited from 13 cancer centers participated in a nationwide survey. Professional Quality of Life scale used to evaluate burnout and multiple regression analysis was performed to identify factors affecting burnout. RESULTS: A total of 144 oncologists were invited, 134 (93.1%) responded, and 130 (90.2%) of those completed the survey. Burnout score of all participants was 49.9, and males was 48.8, females was 53.9, females score was higher than males. According to the hours worked per session, the average burnout score increased with the hours worked per session. Multiple regression analysis showed that influencing or predictive factors in burnout were sex and hours worked per session. CONCLUSION: To reduce burnout in oncologists, organization-directed interventions should be implemented to prevent work overload.

Attributes of caregivers' quality of life: A perspective comparison between spousal and non-spousal caregivers of older patients with cancer.

PURPOSE: With the aging population, our current understanding of patients with cancer and their family caregivers needs to be expanded to older patients with cancer and their caregivers. By differentiating spousal caregivers and non-spousal caregivers, we aimed to investigate the universalities and particularities of caregiving for older patients with cancer. METHODS: Through 11 cancer centers in South Korea, 358 patient-caregiver pairs were recruited in this cross-sectional study. Patients were of gastric, colorectal, or lung cancers, and caregivers were those who accompanied the patients to the clinic. Along with socio-demographic variables, medical records of the patients, and caregiving-related measurements, the caregiver's quality of life (AC-QOL) was rated both by patients and by caregivers. RESULTS: Statistically significant attributes of ACQOL included patient's age, caregiving duration, caregiver's concern about financial burden, caregiver's self-evaluation of their own physical health, and work conflicts due to caregiving for spousal caregivers (R2 = 0.687). For non-spousal caregivers, caregiving duration, caregiver's concern about financial burden, caregiver's self-evaluation of their own physical health, and family conflicts due to work were found significant (R2 = 0.272). Also patients rated ACQOL in higher accordance with their spousal caregivers than with non-spousal caregivers. CONCLUSION: The needs of spousal caregivers and non-spousal caregivers might vary, which should inform the effective and efficient channeling of support for family caregivers. Future research suggestions, along with the study limitations, are discussed.

Patient-family communication mediates the relation between family hardiness and caregiver positivity: Exploring the moderating role of caregiver depression and anxiety.

Purpose: Despite the theoretical and empirical significance of positive aspects of caregiving in caregiver well-being, relatively little is known regarding family-related predictors of caregiver positivity. This study examines whether patient-family communication (p-f communication) mediates the relation between family hardiness and caregiver positivity and whether the mediating effects of p-f communication are moderated by the levels of caregiver depression and anxiety. Design/Sample: This study used secondary data obtained from a large-scale cross-sectional national survey conducted in South Korea. Participants were 544 spousal cancer patient-caregiver dyads recruited from the National Cancer Center and nine government-designated regional cancer centers in South Korea. Methods: To test the hypotheses, a simple mediation model and two moderated mediation tests were conducted using the PROCESS macro for SPSS. Findings: Higher family hardiness was related to higher p-f positive communication and higher caregiver positivity. The effects of family hardiness were partially mediated by p-f communication, controlling for caregiver sex, education, health status, depression and anxiety, time spent caregiving, and patient depression and anxiety, cancer stage, and time since diagnosis. The mediating effects of p-f communication were not significantly moderated by caregiver depression and anxiety. Conclusions/Implications: Health care professionals could consider p-f communication as a reasonable target of intervention to increase caregiver positivity, even for caregivers with heightened depression and anxiety.

A scoping review of consumer needs for cancer information.

OBJECTIVE: This study was a scoping review of research on cancer-related health information seeking and needs of patients, survivor, non-patients, and caregivers. METHODS: This study used the COSI model to search for articles published from 2007 to 2017. RESULTS: In total, 117 articles with titles and abstracts including the following terms were selected: cancer, health, information, seeking. Non-patients obtained information from the Internet, doctors, and media, whereas patients obtained information from doctors, the Internet, and media. Information needs were the highest for treatment, prognosis, and psychosocial support. Patients had the highest need for information on prognosis and treatment, whereas non-patients had the highest need for general cancer information, prevention, and cancer examination. Caregivers sought information about treatment, psychosocial support, and prevention. CONCLUSION: This study revealed an increase in the number of research articles identifying cancer patients' information needs. Cancer patients rely on health professionals for information; thus, relevant materials are needed. Furthermore, not only medical but also psychosocial support information is needed. PRACTICE IMPLICATIONS: There is a need for cancer information from health professionals, and thus for patient-centered training materials. Furthermore, a survey system to evaluate consumers' cancer information needs should be developed.

What We Talk about When We Talk about Caregiving: The Distribution of Roles in Cancer Patient Caregiving in a Family-Oriented Culture.

PURPOSE: When it comes to cancer care, the psychological well-being of family caregivers has gotten its deserved attention. However, the specific roles that the family caregivers take have not been examined as much. The current study aimed to investigate the distribution of family caregivers' roles, particularly in a family-oriented culture, Korea. MATERIALS AND METHODS: A sample of 439 participants was recruited from 11 national and regional cancer centers in Korea. The participants who were 60 years old or above went through treatments for their gastric, colorectal, or lung cancer. The individual survey included questions regarding the family type, living arrangement, and the sources of support when it comes to their physical, emotional, financial, and decision-making needs. RESULTS: The responses from the participants showed that cancer caregiving is shared by multiple family caregivers; the major source of support for elderly cancer patients on diverse domains was their spouse; patients' reliance on their daughter(s) increased for emotional support; and patients' reliance on their son(s) stood out for financial support and decision-making support. Also, the older the patients were, the heavier their reliance was on the adult children, including sons, daughters, and daughters-in-law. CONCLUSION: Future support programs for elderly cancer patients are suggested to involve multiple family caregivers to encourage effective and efficient intervention. Also, the limitations of the current study and the suggestions for future research are discussed.

Experience with age discrimination and attitudes toward ageism in older patients with cancer and their caregivers: A nationwide Korean survey.

OBJECTIVE: It is not clear whether age-related differences in treatment and treatment decision-making are the result of age discrimination or just a reflection of older patients' elevated risk and their own preferences. Therefore, it is critical to understand older patients' own views toward their care in regard to its relationship to age. MATERIAL AND METHODS: 439 older patients with cancer (age ≥ 60) and 358 family members from eleven cancer centers participated in this cross-sectional survey. RESULTS: Almost all patients (91.2%) and caregivers (92.7%) thought that older patients should be treated equal to younger patients, across all questionnaire items. The proportions of patients who reported having experienced age discrimination according to each item were: disease information (12.3%), treatment information (11.0%), participation in treatment decision (10.7%), attention from healthcare professionals (6.2%), supportive care (5.2%), and treatment (3.2%). Increasing age was the only demographic characteristic that was associated with greater ageism experience (p < .001). Patients' ageism attitudes, as well as caregivers' ageism attitudes, were negatively associated with ageism experience. Ageism experience was associated with a higher depression score, as well as a lower quality of life. CONCLUSION: Discrimination in treatment and the treatment decision process based on age was not justified. Interventions that address ageist attitudes in older patients, family caregivers, and healthcare professionals are needed to reduce age discrimination, and thereby improve the quality of life of older patients with cancer.

Income Difference in Attitudes towards Cancer in General Population: Findings from a National Survey.

BACKGROUND: To better understand cancer-related health behaviors, it is critical to know how general populations with different socioeconomic and demographic backgrounds perceive cancer. The current paper explored differences in general attitudes and beliefs towards cancer among Koreans. METHODS: A cross-sectional national survey was conducted for 1,000 Korean participants who were not cancer patients and did not have immediate family members with cancer via proportional quota random sampling. General attitudes and beliefs about cancer were measured by face-to-face interview using the awareness and beliefs about cancer (ABC) measure. RESULTS: Most respondents (84.8%-88.5%) had optimistic attitudes towards cancer. However, 35.6% to 87.7% agreed with negative cancer beliefs across all age groups simultaneously. Socioeconomic disparity of positive cancer beliefs was not evident. Unexpectedly, the highest income group agreed more strongly with the negatively framed statements that cancer treatment is worse than the cancer itself (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.31-5.53), that they would not want to know if they have cancer (OR, 1.61; 95% CI, 0.94-2.75), and that a cancer diagnosis is a death sentence (OR, 2.32; 95% CI, 1.34-4.01), than the lowest income group. CONCLUSION: The present results imply a complicated context of cancer beliefs in Korea, unlike those shown in the studies of western populations. While the contradictory attitudes toward cancer can be attributable to the dual nature of information processing, social environment might have played a role. The association between socioeconomic status and negative attitudes toward cancer may vary depending on the diversity of the contexts.

Physicians' attitudes towards the media and peer-review selection of the 'best cancer doctor': comparison of two different selection methods.

OBJECTIVES: The choice of doctor is an important issue for patients with cancer, and the reputation of the doctor is the single most important factor for patients to choose a doctor. Media are providing information about the 'best cancer doctor', but they vary widely in their selection methodology. We investigated cancer physicians' attitudes towards the selection of the 'best cancer doctor' by the media, by comparing two different selection methodologies: selection by media personnel or selection through peer-review system. DESIGN: Nationwide, cross-sectional survey. SETTING: National Cancer Center and 12 Regional Cancer Centers across Korea. PARTICIPANTS: A total of 680 cancer care physicians participated in the survey (75.5% participation rate), and two were excluded due to incomplete response. MAIN OUTCOME MEASURES: Physicians' opinions on the credibility, fairness, validity, helpfulness to patients, their intention to use the information and helpfulness to improve the quality of cancer care of the two different methods. RESULTS: Only a few physicians believed that the selection method of the 'best cancer doctor' by the media personnel was credible (9.1%), fair (6.1%) or valid (10.0%). In contrast, the majority agreed that the peer-selection method of the 'best doctor' is credible (74.7%), fair (64.7%) and valid (67.4%). More physicians believed the latter methods would be useful for patients when selecting their doctor (38.5% vs 82.2%) and may lead to improvement of the quality of cancer care from the perspective of the healthcare system (12.6% vs 59.8%). The need for ensuring objectiveness and transparency was also raised. CONCLUSION: Physicians showed different attitudes towards two different selection methods. Regulations or guidelines for selecting the 'best cancer doctor' and for disclosing the information should be considered in order to control the quality of the information and to protect the customers.

Cancer cost communication: experiences and preferences of patients, caregivers, and oncologists-a nationwide triad study.

PURPOSE: We assessed cost communication between cancer patients, caregivers, and oncologists and identified factors associated with communication concordance. METHODS: A national, multicenter, cross-sectional survey of patient-caregiver-oncologist triads was performed, and 725 patient-caregiver pairs, recruited by 134 oncologists in 13 cancer centers, were studied. Discordance in preferences and experiences regarding cost communication between patients, caregivers, and oncologists were assessed. Hierarchical generalized linear models were used to identify predictors of concordance and to identity the possible association of concordance with patient satisfaction and degree of trust in the physician. RESULTS: Although the oncologists thought that patients would be affected by the cost of care, only half of them were aware of the subjective burden experienced by their patients, and the degree of concordance for this parameter was very low (weighted kappa coefficient = 0.06). Caregivers consistently showed similar preferences to those of the patients. After controlling for covariates, the education level of patients [adjusted odds ratio (aOR) for > 12 vs. < 9 years, 2.92; 95% confidence interval (CI), 1.87-4.56], actual out-of-pocket costs [aOR for ≥ 8 million vs. < 2 million Korean Won, 0.56; 95% CI, 0.34-0.89], and physician age (aOR for ≥ 55 vs. < 45 years, 1.83; 95% CI, 1.04-3.21) were significant. CONCLUSIONS: The results show underestimation by oncologists regarding the subjective financial burden on a patient, and poor patient-physician concordance in cost communication. Oncologists should be more cognizant of patient OOP costs that are not indexed by objective criteria, but instead involve individual patient perceptions.

Type 1 diabetes mellitus and risk of cancer: a meta-analysis of observational studies.

OBJECTIVE: Previous observational studies have focused on the link between type 2 diabetes and the risk of cancer. However, the association between type 1 diabetes and the risk of cancer has not been well addressed. This study aimed to investigate the association between type 1 diabetes and the risk of cancer by using a meta-analysis of observational studies. METHODS: We searched PubMed and EMBASE for observational studies that examined the association between type 1 diabetes and cancer in April 2017. We calculated the pooled odds ratios (ORs) or relative risks (RRs) with confidence intervals (CIs) from individual studies based on a random-effects model meta-analysis. RESULTS: We included a total of 15 observational studies with two case-control studies and 13 cohort studies involving 31 893 cancer patients among a total of 1 915 179 participants in the final analysis. In the random-effects meta-analysis of all studies, patients with type 1 diabetes had an increased risk of cancer (OR or RR, 1.29; 95% CI, 1.09-1.52; n = 15; I2 = 95.2%). In the subgroup meta-analysis by type of cancer, type 1 diabetes significantly increased the risk of cancers of stomach, lung, pancreas, liver, ovary and kidney, whereas it significantly decreased the risk of breast cancer (OR or RR, 0.91; 95% CI, 0.86-0.95; n = 9; I2 = 0%). CONCLUSION: This meta-analysis suggests that type 1 diabetes is associated with the increased risk of several types of cancer and the decreased risk of breast cancer. However, the plausible mechanisms for the decreased risk of breast cancer remain unclear. Further prospective studies with proper adjustment for possible confounding factors are warranted.

Patients' and family caregivers' understanding of the cancer stage, treatment goal, and chance of cure: A study with patient-caregiver-physician triad.

OBJECTIVE: Accurate understanding of the extent of disease, treatment goal, and prognosis is a prerequisite for patients with cancer and their caregivers to make informed decision. We sought to evaluate patients' and family caregivers' understanding of the cancer stage, treatment goal, and chance of cure taking their own physician's evaluation as reference. METHODS: A national survey was performed with 750 patient-caregiver dyads (75.5% participation rate) recruited by 134 oncologists in 13 cancer centers (93% participation rate) in South Korea. Both patients and caregivers were asked to report their knowledge of patient's cancer stage, treatment goal, and chance of cure. Concordance was evaluated with percentage agreement and weighted κ, and predictors of discordance of patient and caregiver's response with that of physician's were explored by multivariate regression analyses with mixed effect model. RESULTS: The agreement rates between patient-physician and caregiver-physician were 63.0% and 65.9% for disease stage, 69.0% and 70.0% for treatment goal, and 41.4% and 45.1% for chance of cure. When discordance occurs, patients and caregivers often had an optimistic view. Distant stage, older age, female sex, and absence of depression were associated with optimistic view of patients, and there was significant between-physician variance for all 3 outcomes. CONCLUSION: The discordance revealed that our study suggests the need for better communication between physician and patients, as well as the caregivers. Research is needed to develop a comprehensive strategy to improve the understanding of the patients and family so that treatment decisions are made based on realistic estimation.

Patient's Cognitive Function and Attitudes towards Family Involvement in Cancer Treatment Decision Making: A Patient-Family Caregiver Dyadic Analysis.

PURPOSE: Older patient populations commonly have cognitive impairment, which might impact decisional capacity. We examined patients and family caregivers preferences for family involvement in treatment decision making assuming different level of cognitive impairment, and sought to explore the factors associated with the preferences and the degree to which patients and family members agree on preferences. MATERIALS AND METHODS: A total of 358 elderly cancer patient and caregiver dyads were recruited from the 11 cancer centers in Korea andwere asked to express their preferences forfamily involvement in treatment decision making using hypothetical scenarios with three different levels of cognitive status (intact, mild impairment, and severe impairment). RESULTS: Both patients and family caregivers preferred greater family dominance in treatment decision makingwith the increasing the level of cognitive impairment (39.7%, 60.9%, and 86.6% for patients and 45.0%, 66.2%, and 89.7% for caregivers in each scenarios). Patient and family caregiver concordance in decisional control preference was small for all three scenarios (weighted κ=0.32, κ=0.26, and κ=0.36, respectively). Higher patient education was associated with preference for patient dominance in treatment decision in conditions of both mild and severe cognitive impairment. The association of higher patient education and patient-caregiver preference concordance was positive with intact cognition, while it was negative with severe cognitive impairment. CONCLUSION: Decision control preferences were affected by hypothesized cognitive status of the patients. Findings from our study would be helpful to develop effective strategy for optimizing family involvement in cancer treatment decision in the context of deteriorating cognitive function of the patients.

Supporting Low-income Cancer Patients: Recommendations for the Public Financial Aid Program in the Republic of Korea.

PURPOSE: As the recent term of "financial toxicity" implies, cancer causes a treatment-related financial harm. Financial Aid Program for Cancer Patient (FAPCP) is a government's financial support for low-income patients in the Republic of Korea. This study aimed to describe FAPCP applicants' condition and to investigate factors influencing financial burden, which would provide the basis for implementing a strategy for FAPCP administration. MATERIALS AND METHODS: The telephone survey results from 2,700 FAPCP participants were analyzed, including demographic, socioeconomic, and disease characteristics and experiences associated with financial burden and the actions or measures to cope with them. RESULTS: Overall, 87.6% experienced financial burden more than moderate degree, 39.2% got financial help/a loan, 17.8% disposed of their property, and 10.2% changed or stopped treatment owing to medical costs. Monthly household income was connected to financial burden, and the highest income group was associated with the lowest financial burden (odds ratio [OR], 0.21; 95% confidence interval [CI], 0.11 to 0.38) and the lowest rate of changing/stopping care (OR, 0.23; 95% CI, 0.05 to 1.00). Parents of childhood cancer patients got financial help/a loan (OR, 2.24; 95% CI, 1.03 to 4.88) and disposed of their property (OR, 3.18; 95% CI, 1.40 to 7.22) more frequently, and Medical Aids applicants showed the highest rate of changing/stopping care (OR, 3.01; 95% CI, 1.89 to 4.78). CONCLUSION: FAPCP targets low income groups; however, financial burden and the consequent actions taken still exist disproportionately, depending on the income of the applicants. FAPCP should focus on more vulnerable groups including Medical Aid applicants and parents of childhood cancer patients, by increasing funds and expanding their support coverage.

Perceived social support and its impact on depression and health-related quality of life: a comparison between cancer patients and general population.

OBJECTIVE: It is well known that cancer patients' perception of social support is associated with their depressive symptoms and health-related quality of life. However, there have been little studies that compared the variates of cancer patients with the general population. We sought to compare differences in the level of perceived social support and the impact of perceived social support on depressive symptoms and health-related quality of life between cancer survivors and the general population. METHODS: Data were collected from 1818 cancer patients treated at the National Cancer Center and regional cancer centers in South Korea. The control group of the general population was composed of 2000 individuals without cancer from community. RESULTS: Cancer patients reported significantly higher level of perceived social support than the general population, while they reported lower health-related quality of life and were more susceptible to depression. The positive associations of higher perceived social support with lower depressive symptoms, as well as with higher health-related quality of life, were stronger among cancer patients than among the general population. CONCLUSIONS: The interaction effect suggests that the impact of social support would be stronger among cancer patients than the general public. Thus, it would be beneficial to pay attention to providing social support to cancer patients, particularly to those who are more vulnerable. Furthermore, investigation of the most effective and efficient methods to deliver social support interventions would be worthwhile.

Cross-cultural application of the Korean version of the EORTC QLQ-ELD14 questionnaire for elderly patients with cancer.

OBJECTIVES: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-ELD14 is a validated tool that measures Health-related Quality-of-life (HRQOL) for elderly patients with cancer. This study was conducted to evaluate the psychometric properties of the Korean version of the EORTC QLQ-ELD14 to determine if this tool can be used to evaluate HRQOL for older Korean patients with cancer. MATERIALS AND METHODS: We recruited 439 elderly patients with cancer aged ≥60years from 11 cancer centers and completed the EORTC QLQ-ELD14 questionnaires. The reliability and validity of the EORTC QLQ-ELD14 questionnaire were assessed via Cronbach alpha, multitrait scaling analyses, correlation analyses with the EORTC QLQ-C30, and known-group comparisons. Known-group comparisons were conducted by dividing the patients into groups based on the cancer stage, depression level, and loss of mobility. RESULTS: The scale structure of the Korean version of the EORTC QLQ-ELD14 was consistent with the originally hypothesized scale structure. Cronbach alpha coefficients ranged 0.65-0.88. Multitrait scaling analysis showed good item convergent and discriminant validity. Low scaling errors (3.1%) were observed. Divergent validity was demonstrated by no strong correlation with the EORTC QLQ C30. The clinical validity of the Korean version of the EORTC QLQ-ELD14 was demonstrated by its ability to discriminate among patient subgroups categorized by AJCC stage, depression level, and loss of mobility. CONCLUSION: Our findings indicate that the Korean version of the EORTC QLQ-ELD14 questionnaire is reliable and valid for measuring QOL of older Korean patients with cancer.
