  • Objective: To investigate the relationship between the perception of cancer risk and likelihood of having undergone cancer screening. Materials and Methods: We used data from the Korean Health Panel Survey from December 2011 onward. Of 3,390 patients who visited a hospital during the previous year, we included data from 2,466 individuals; 924 samples were excluded due to missing data. Logistic regression analysis and the chi square test were used to investigate the association between perceived cancer risk and the likelihood of having undergone cancer screening. Results: For patients who perceived their risk of developing cancer during the next 10 years to be 30-40%, the odds ratio was increased 1.65 fold (95%CI: 1.223, 2.234) compared with those who perceived their risk to be almost zero. Although the difference was not statistically significant, perceiving cancer risk as either extremely low or extremely high appears to be associated with a reduced likelihood of having undergone cancer screening, resulting in an inverted U-shaped relationship. Conclusions: Physicians and researchers should be aware of the importance of the affective component of risk perception. Policies addressing the influence of cancer risk perception should be implemented in South Korea and worldwide.

  • Purpose Low-dose computed tomography (LDCT) has been reported as an effective screening method for lung cancer in high-risk populations. We aimed to examine willingness to be screened among Korean males using LDCT and to determine factors associated with lung cancer screening intentions (LCS) based on the Health Belief Model (HBM). Materials and Methods Data were obtained from the 2015 Korean National Cancer Screening Survey, a cross-sectional survey that utilized nationally representative random sampling. The survey included 1,730 male participants 40-74-year-old. Respondents were questioned regarding their willingness to undergo LCS and components of HBM. Factors associated with intentions to undergo screening were explored using logistic regression. Results Among participants, 65.2% were current smokers. Among high-risk subjects, 60.6% of men reported intentions to undergo LCS, compared to 49.9% of average-risk males. Men with higher perceived susceptibility in the average- and high-risk groups were, respectively, 1.63 (95% confidence interval [CI], 1.39 to 1.91) and 2.30 (95% CI, 1.14 to 4.63) times more likely to intend to undergo LCS compared to those with lower perceived barriers. Also, men in the average- and high-risk groups with higher perceived barriers to screening were, respectively, 0.79 (95% CI, 0.68 to 0.91) and 0.52 (95% CI, 0.29 to 0.92) times less likely to intend to undergo LCS compared to those with lower perceived barriers. Conclusion Tailored interventions designed to promote accurate perceptions of susceptibility and risk, as well as to reduce perceived barriers to screening, may effectively increase adherence to recommendations for LCS among high-risk Korean men.

  • Iranian women are at high risk of low compliance with repeat mammography due to a lack of awareness about breast cancer, negative previous experiences, cultural beliefs, and no regular visits to a physician. Thus research is needed to explore factors associated with repeated mammography participation. Applying the concept of perceived risk as the guiding model, this study aimed to test the fit and strength of the relationship between perceived risk and physician recommendation in explaining repeat mammography. A total of 601 women, aged 50 years and older referred to mammography centers in region 6, were recruited via a convenience sampling method. Using path analysis, family history of breast cancer and other types of cancer were modeled as antecedent perceived risk, and physician recommendation and knowledge were modeled as an antecedent of the number of mammography visits. The model explained 49% of the variance in repeat mammography. The two factors of physician recommendation and breast self-examination had significant direct effects (P < 0.05) on repeat mammography. Perceived risk, knowledge, and family history of breast cancer had significant indirect effects on repeat mammography through physician recommendation. The results of this study provide a background for further research and interventions not only on Iranian women but also on similar cultural groups and immigrants who have been neglected to date in the mammography literature.

  • Background: As coverage of public insurance is not sufficient to cover diagnosis or treatment of cancer, having private health insurance is important to prepare for unexpected expenses of cancer. The purpose of this study was to assess factors associated with having private cancer insurance, considering gender among the socio-demographic factors and health behavior. Materials and Methods: We used data from the 2011 Korea Health Panel, which included 10,871 participants aged 20 years and older. Socio-demographics, health behavior, and perceived cancer risk were the independent variables and having private cancer insurance was the dependent variable. Multivariable logistic regression analysis was used to identify factors associated with having private cancer insurance. Results: The variables relating to middle age, higher education, higher household income, married men, and the perceived cancer risk groups of 1-10% and 11-30% were significantly associated with having private cancer insurance. Additionally, females who had private non-cancer health insurance were positively associated with the dependent variables (OR=1.36; 95% CI=1.17-1.57). Education, smoking status, exercise, and perceived cancer risk possibility were significantly associated with having private cancer insurance only among women. The men lowered the overall percentages of those having private cancer insurance (OR=0.53, 95% CI=0.45-0.63). Conclusions: We found that there were significant differences between men and women who had private cancer insurance. Women with private cancer insurance are more likely to follow precautionary health behavior than men. This could be interpreted as resulting from masculine ideologies. It is important to make males recognize the seriousness of the cancer risk. In general, household income was highly associated with private cancer insurance. These results reveal an inequity among the buyers of private cancer insurance in terms of economic status level, education level, and health condition.

  • Background: Outcome-expectation beliefs and knowledge may ultimately influence behavior for cancer prevention. The aims of this study were to measure changes in knowledge and beliefs about cancer prevention before and after viewing a television advertisement and identify the factors affecting receptivity to its messages. Materials and Methods: A one-group pretest-posttest design was used in this study of 1,000 individuals aged 20 to 65 years who were recruited online in November 2014. The outcome variables included cancer prevention beliefs based on the Health Belief Model (five items) and knowledge about risk factors for cancer (seven items). Results: Perceived susceptibility, perceived benefits, and self-efficacy increased significantly and their perceived severity and perceived barriers decreased significantly, after participants viewed the television advertisement. Correct responses to questions about risk factors also increased significantly, except for smoking. The main factors affecting changes in the outcome variables were age, interest in cancer prevention, social network, satisfaction with the ad, and pretest scores. Conclusions: Television advertisements with positive frameworks can be an efficient channel of improving beliefs and knowledge about cancer prevention in a short period. The continuous development of intervention materials that consider the demographics, needs, and satisfaction of the target group will be necessary for future studies.

  • Objective : The objective of this study was to examine how experts and the public perceived various environmental and technological hazards based on psychometric paradigm. Methods : We conducted a survey that included 30 hazards and 10 risk attributes. Subjects of this study were 214 people with three groups; (1) experts (55 people), (2) graduates( 78 people), (3) under graduates (81 people). Factor analysis was used to confirm the common risk attribute from 8 risk attributes. Also, multiple regression analysis was used to identify factors influencing on perceived risk and benefit of hazards. Results : This study revealed that experts tend to be more tolerant than graduates and under graduate students for the 30 hazards. Using factor analysis, two main factors were identified: factor 1, commonly called "Dread Risk", and factors 2, commonly called, "Unknown Risk" in the literature. We identified that environmental hormone concentration and global warming ranked high in both dread risk and unknown risk. Multiple regression models were used to test the association of perceived social risk and perceived social benefit with two main factors. Dread risk had significant explanatory power on perceived social risk and benefit. We identified that the experts were less likely to perceived dread risk and know more information about the hazards. Conclusions : There were differences of risk perception between experts and lay people. Especially, experts' perception of risk was commonly lower than other people's perception.

  • A case-control study was conducted in order to examine dietary behavioral factors associated with colorectal cancer risks. Data were collected from 128 cases with either colorectal cancer or large bowl adenomatous polyps and 129 controls regarding stages of dietary behavioral change, perceived barrier, self efficacy, nutrition knowledge, social support and food availability as well as body mass index and overall dietary quality. Cases showed less desirable behaviors with respect to fat reduction and vegetable intake compared with controls based on the analyses of the stages of dietary change. After adjustment of relevant covariates (age, gender and smoking), significant trends of increasing risk with higher level emerged for perceived barriers resulted from environmental conditions (OR = 1.6 - 2.0) and self-efficacy (OR = 2.2-2.3). No such relationships were found for nutrition knowledge and social support. The risk of colorectal cancer was associated with the kinds of foods available at home showing a borderline protective relation with milk (OR = 0.6) and respective significant and borderline direct associations for fresh meat (OR = 2.1) and soft drinks (OR = 0.6 when reversely scored). Within-group analyses presented best predictors of overall dietary quality as food availability for the case and self-efficacy and social support for the control. The findings of this study suggested a need for focusing on motivational and reinforcing factors in the development of nutrition education programs for colorectal cancer prevention.

  • Background: This study aimed to seek insights into Chinese women's lay beliefs about cervical cancer causal attributions and prevention. Materials and Methods: Twenty-three new immigrant adult women from Mainland China and thirty-five Hong Kong adult women underwent semi-structured in-depth interviews. Interviews were audio taped, transcribed and analyzed using a Grounded Theory approach. Results: This study generated three foci: causal beliefs about cervical cancer, perceived risk of cervical cancer, and beliefs about cervical cancer prevention. Personal risky practices, contaminated food and environment pollution were perceived as the primary causes of cervical cancer. New immigrant women more likely attributed cervical cancer to external factors. Most participants perceived cervical cancer as an important common fatal female cancer with increased risk/prevalence. Many participants, particularly new immigrant women participants, expressed helplessness about cervical cancer prevention due to lack of knowledge of prevention, it being perceived as beyond individual control. Many new immigrant participants had never undergone regular cervical screening while almost all Hong Kong participants had done so. Conclusions: Some Chinese women hold pessimistic beliefs about cervical cancer prevention with inadequate knowledge about risk factors. Future cervical cancer prevention programs should provide more information and include capacity building to increase Chinese women's knowledge and self-efficacy towards cervical cancer prevention.

  • Purpose: This study was to explore the hope structures of the newly diagnosed cancer patients by examining the relationships between hope and the three concepts of 'Personal Spirit', 'Risk' and 'Authentic Caring' which composed the multidimensions of the Nekolaichuk and Bruera's hope model. Methods: Data was collected via survey from 32 newly diagnosed cancer patients. The perceived meaning of life (PML) for 'personal spirit', perceived confidence in cure (PCC) for 'risk', and perceived family support (PFS) and perceived support from medical team (PSM) for 'authentic caring' were adapted from the definitions of the concepts in the model. Hope, PML, and PCC were measured with VAS. PFS and PSM were measured with Korean version of 'Cobb's family support scale', which was modified by Kang. Pearson correlation coefficients were used to identify the relationships among the concepts. Results: The significant relationships were revealed between hope and PCC (p<.001), hope and PML (p<.001), PML and PCC (p<.001), PFS and PML (p=.030), and PSM and PML (p=.047). Conclusion: The newly diagnosed cancer patients experience hope in different ways. The cancer patients' hope immediate after diagnosis, however, is most likely to be experienced as seeking balance between uncertainty about cancer treatment and the meaning of life.
