[Developing a Japanese version of the Digital Health Literacy Instrument].

Objectives　The Internet has made it possible to search for, obtain, transmit, and share information. Accordingly, the ability to use health information and skills related to interactivity taken from the Internet have become important in the medical and health fields. However, there is no scale to evaluate these abilities. Therefore, this study was conducted to assess the validity and reliability of the Digital Health Literacy Instrument (DHLI) and examine the association of digital health literacy (DHL) with the characteristics of the study participants.Methods　The Japanese version of the DHLI was developed using the basic guidelines for scale translation. The participants included 2,000 Japanese adults (men: 50.0%, mean age: 40.7±12.0 years) who responded to an Internet-based cross-sectional survey. The Japanese version of the DHLI, attributes, sources of health information, contents of health information taken from the Internet, and eHealth Literacy Scale (eHEALS) scores were obtained using a questionnaire. Confirmatory factor analysis and correlation with eHEALS scores were used to assess construct and criterion validities. Cronbach's alpha and correlation coefficients were computed for internal consistency and test-retest reliability. Differences in DHLI scores for each attribute and variables related to health information were examined using the analysis of variance and t-test.Results　Confirmatory factor analysis revealed a goodness-of-fit index of .946, a comparative fit index of .969, and a root mean square error of approximation of .054, confirming that the Japanese version has the same seven-factor structure as the original version does. A significant positive correlation was found between DHLI and eHEALS scores (r=.40, P<.001). Cronbach's alpha was .92, and test-retest reliability was r=.88 (P<.001). DHLI scores were mainly associated with household income, health status, frequency of information searches on the Internet, and devices used. The subscale scores found difficulties in evaluating reliability, determining relevance, and adding self-generated content. Differences in DHL were observed among some sources and contents of health information on the Internet.Conclusion　The Japanese version of the DHLI was a sufficiently reliable and valid instrument for assessing DHL among Japanese adults. Our results suggest that low DHL may lead to health information disparities. Therefore, it is necessary to consider support strategies for individuals who need to improve their DHL and for skills that need to be strengthened.

Effect modification by geographic area on the association between health literacy and self-rated health: a nationwide cross-sectional study in Japan.

BACKGROUND: Health literacy (HL) has gained increasing attention as a factor related to health behaviors and outcomes. This study aimed to investigate geographic differences in HL levels and effect modification by geographic area on their relationship with self-rated health in the Japanese population using a nationwide sample. METHODS: Data for this study were derived from a nationally representative cross-sectional survey on health information access for consumers in Japan using a mailed self-administered questionnaire in 2020 (INFORM Study 2020). Valid responses from 3,511 survey participants, selected using two-stage stratified random sampling, were analyzed in this study. HL was measured using the Communicative and Critical Health Literacy Scale (CCHL). Multiple regression and logistic regression analyses were conducted to examine the associations between geographic characteristics and HL and effect modification on the association between HL and self-rated health by geographic area, controlling for sociodemographic characteristics. RESULTS: The mean HL score was 3.45 (SD = 0.78), somewhat lower compared with previous studies on the Japanese general population. HL was higher in Kanto area than in Chubu area, after controlling for sociodemographic factors and municipality size. Furthermore, HL was positively associated with self-rated health after controlling for sociodemographic and geographic factors; however, this association was more evident in eastern areas than in western areas. CONCLUSION: The findings indicate geographic differences in HL levels and effect modification by geographic area on the relationship between HL and self-rated health in the general Japanese population. HL was more strongly associated with self-rated health in eastern areas than in western areas. Further investigation is needed to explore the moderating effects of areal features, including the distribution of primary care physicians and social capital, when formulating strategies to improve HL in different contexts.

Health literacy and COVID-19-related beliefs and behaviors: a longitudinal study of the Japanese general population.

Since the outbreak of novel coronavirus disease-2019 (COVID-19), health communication has played a critical role in the process of disease prevention. Based on the concepts of health literacy and protection motivation theory, this study longitudinally examined the relationship between general health literacy measured immediately before the COVID-19 outbreak, and COVID-19-related information utilization, health literacy, beliefs and protective behaviors during the subsequent year in the Japanese general population. The participants were 767 Japanese residents who completed self-administered questionnaire surveys in January 2020 and February 2021. Based on the hypotheses, we constructed and tested a path model to predict the adoption of protective behaviors. Higher health literacy in 2020 was significantly related to higher COVID-19-related health literacy in 2021, which, in turn, was related to the adoption of recommended protective behaviors both directly and indirectly through threat and coping appraisal. Coping appraisal, but not threat appraisal, significantly differed by health literacy level. Generic health literacy skills for accessing, understanding and applying health information may enable people to better adapt to specific health risks. Our findings provide guidance for future health literacy education and health risk communication in populations with different health literacy levels.

Using patient storytelling to improve medical students' empathy in Japan: a pre-post study.

BACKGROUND: Empathy for patients is now internationally accepted as one of the competencies of physicians for patient-centered medical practice and an essential component of medical education. Recently, "patient storytelling" has attracted attention in empathy education for medical students to understand patients' experiences, feelings, and perspectives. This study aimed to quantitatively evaluate how patient storytelling enhanced undergraduate medical students' empathy in Japan to the extent that they sustained it for six months. METHODS: Participants were 159 fourth-year undergraduate medical students in Tokyo in academic years 2018 and 2019. The questionnaire surveys were conducted three times: at the beginning of the class, immediately after the class, and six months after the class. The Japanese version of the Jefferson Scale of Empathy-Student Version was used in this study. Gender, age, and clinical orientation were also obtained through the self-reported questionnaire. We invited a male patient storyteller who was diagnosed with chronic kidney disease to the classes on "Professionalism." The title of his storytelling was "The Power of Medical Professionals' Words." RESULTS: JSE-S scores improved significantly immediately after listening to patient storytelling. The scores remained improved six months after the class. Interest of specialty was significantly positively associated with an immediate change in JSE-S scores. However, gender had no significant association with changes in JSE-S scores either immediately or six months after education. CONCLUSIONS: Our findings may suggest that patient storytelling would be useful to cultivate empathy among undergraduate medical students. It is to be expected that more medical schools will use patient storytelling to educate medical students in humanistic and communication education.

Association between health indifference and problem drinking using a nationwide internet survey.

BACKGROUND: Little is known about the vulnerable populations and problem drinking in terms of health inequality. This study aimed to investigate the relationship between health indifference estimated by Health Interest Scale (HIS) and problem drinking identified by the Alcohol Use Disorder Identification Test (AUDIT). METHODS: A cross-sectional study was conducted utilizing data from a nationwide internet survey in Japan in 2022. The number of total participants was 29,377, with 49% of them being male, and the mean age was 47.9 (±17.9) years. The participants were categorized into the following groups based on the quintiles of HIS score: health indifference (0-16), low health interest (17-20), middle health interest (21-22), middle-high interest (23-26) and high health interest (27-36) groups. Problem drinking was identified as AUDIT score of ≥8 points. RESULTS: The association between health indifference and problem drinking was explored through logistic regression with adjustment for various socioeconomic status, such as education, income level, and occupation; the adjusted odds ratio (aOR) was 1.72 [95% confidence interval (CI): 1.51-1.95]. CONCLUSION: Health indifferent or lower health interest groups were a vulnerable population for problem drinking, regardless of their socioeconomic status. It could be useful to identify the health indifferent group through HIS and to monitor the impact of health intervention for this group for the reduction of health inequality.

The relationship between evaluation of shared decision-making by pet owners and veterinarians and satisfaction with veterinary consultations.

BACKGROUND: Communication skills are a necessary competency in veterinary medicine, and shared decision-making (SDM) between practitioners and patients is becoming increasingly important in veterinary practice as in human medicine. There are few studies that have quantitatively measured SDM in veterinary health care, and the relationship between SDM and consultation satisfaction is unknown. The purpose of this study was to investigate the status of SDM implementation in veterinary hospitals and the relationship between SDM implementation and consultation satisfaction among pet owners. We conducted a cross-sectional study using self-administered questionnaires among pet owners and veterinarians. In total, 77 pet owners who visited a veterinary clinic and 14 veterinarians at the clinics participated in this study. After a veterinary clinic visit, owners were asked to rate their decision-making preferences using the Shared Decision Making Questionnaire for patients (SDM-Q-9) adapted for veterinary medicine, as well as their satisfaction with the consultation. The corresponding veterinarians were asked to complete the veterinary version of the survey (SDM-Q-Doc). RESULTS: Most pet owners (64.9%) preferred SDM in veterinary consultations. Cronbach's alpha coefficient of 0.84 for the veterinary SDM-Q-9 and 0.89 for the veterinary SDM-Q-Doc both confirmed high reliability. The Spearman's correlation coefficient between the SDM-Q-9 and consultation satisfaction was 0.526 (p < 0.001), which was significant. The SDM-Q-Doc was not significantly correlated with either the SDM-Q-9 or pet owner consultation satisfaction. We conducted a sensitivity analysis of correlations among veterinarians; responses on the SDM-Q-Doc to examine the association between the SDM-Q-Doc and SDM-Q-9 and owner satisfaction; the results remained the same and no association was found. CONCLUSIONS: Our findings suggest that evaluation of SDM among pet owners was associated with their satisfaction with veterinary consultation. Veterinarians may be able to improve the satisfaction level of pet owners by adopting a consultation method that increases SDM. We did not consider the content of veterinary care or the number of visits to the veterinary clinic; future studies should be conducted to confirm the validity of our results.

Patterns of alcohol and alcohol-flavoured non-alcoholic beverage advertisements over Japanese free-to-air television networks.

BACKGROUND: Alcohol use is a serious public health challenge worldwide. Japan has no government regulations or legal penalties against advertising alcoholic beverages on television (TV). Instead, advertisements depend on the Japanese alcohol industry's self-regulation on airtime (no advertisements from 5 am to 6 pm) and the content of alcoholic beverages, which must not tempt minors. However, many adolescents (10 to 19 years old) watch TV from 6 pm to 11 pm. The aim of this study was to describe the pattern in the advertising of alcoholic beverages and alcohol-flavoured non-alcoholic beverages (AFNAB) in Japan during the popular TV viewing time for adolescents. METHODS: A secondary analysis of advertising airtime data from five free-to-air Japanese TV networks in the Greater Tokyo area that aired between 12 August and 3 November 2019, was performed. RESULTS: During the study period, 5215 advertisements for alcoholic beverages and AFNABs aired (1451.75 min). In total, 2303 advertisements (44.2%) were beer, low-malt beer, or beer-taste beverages, 277 (5.3%) were whisky, 2334 (44.8%) were local alcoholic beverages (shochu and seishu), and 301 (5.8%) were AFNAB. On average, more advertisements aired on weekends (67.6 advertisements) than on weekdays (59.3 advertisements) per day. Approximately 30% of advertisements for AFNABs were aired during the time restricted for alcohol advertising, although AFNABs are considered alcohol according to industry guidelines. During the popular television viewing time for young adolescents, about two to three times more advertisements were aired per hour than during the rest of the day, on both weekdays and weekends (p < 0.001). CONCLUSION: The number of alcohol advertisements aired at times when adolescents often watch TV is 2 to 3.2 times higher than that at other times of the day. Furthermore, despite the industry's self-imposed regulations, some alcoholic beverages are still advertised. Therefore, other methods to protect children and adolescents from exposure to advertisements for alcoholic beverages should be investigated and implemented.

Declines in health literacy and health-related quality of life during the COVID-19 pandemic: a longitudinal study of the Japanese general population.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, the importance of health literacy (HL) was addressed by public health researchers. We longitudinally examined the changes in general HL and health-related quality of life (HRQOL) between immediately before the COVID-19 outbreak and 1 year later, and how general HL before the outbreak was related to changes in HRQOL in the Japanese general population. METHODS: Among the Japanese residents aged 20-79 years who participated in our previous study in 2017, 826 were followed-up via self-administered questionnaires in January 2020 and February 2021, for the purposes of this study. The HRQOL was measured using the SF-8, a short version of the SF-36 Health Survey, and general HL was measured using the short form of the European Health Literacy Survey Questionnaire (HL-SF12) in the 2020 and 2021 surveys. RESULTS: The physical and mental dimensions of HRQOL as well as general HL declined significantly from immediately before the COVID-19 outbreak to 1 year later (p = .010, p < .001 and p < .001, respectively). The decline in HRQOL, especially the mental dimension, was more significant among women. A lower economic status was also related to a greater decline in HRQOL (p = .026 for the physical dimension and p = .012 for the mental dimension). Higher general HL before the COVID-19 outbreak was associated with a lesser decline in HRQOL in both the physical and mental dimensions (p = .040 and p < .001, respectively) after controlling for possible confounding variables such as gender and economic status. CONCLUSIONS: Healthcare support is crucial for vulnerable populations during and after the pandemic. General HL may be important for attenuating the decline in HRQOL, by enabling effective use of health information and adaptive behaviors toward health threats. Further studies are needed to better understand the association between HL and HRQOL.

[Change in dietary consciousness and its related factors among Japanese adults under the COVID-19 pandemic: Analysis using Dietary Consciousness Scale].

Objectives　This study aims to develop a dietary consciousness scale and examine its reliability and validity, as well as investigate the changes in psychological aspects that influence diet among Japanese adults during the COVID-19 pandemic and clarify its related factors.Methods　An online survey was conducted from July 1, 2020 to July 3, 2020. Participants were adults aged between 20 and 69 years selected from 13 prefectures where the government declared the state of emergency from April to May 2020. All selected participants were shopping or cooking foods for more than 2 days a week at the time of the survey. A total of 2,299 participants were included in the analysis. Dietary consciousness was measured using 12 items, and the construct was examined using factor analysis. Cronbach's alpha was examined as an indicator of internal validity, and the criterion-referenced validity was confirmed using the Kruskal-Wallis test. To determine changes in dietary consciousness, we calculated total scores based on changes in each item of the Dietary Consciousness Scale as follows: no change (0 points), improved (+1 point), and worsening (-1 point). The associations between the changes in dietary consciousness and characteristics or socioeconomic factors of the participants were examined using the chi-squared test and residual analysis.Results　Exploratory and confirmatory factor analyses demonstrated that a model consisting of two factors fitted the data (GFI = 0.958, AGFI = 0.938, CFI = 0.931, RMSEA = 0.066). Cronbach's alpha of the first factor (importance of diet) was 0.838 and 0.734 for the second factor (precedence of diet), and the reliability was confirmed at 0.828 for the entire scale. In the examination of criterion-related validity, the higher the stage of change, the higher the total score of the scale, and a significant difference was observed (P<0.001). The percentage of participants whose precedence worsened was higher than the importance. Significant differences were observed regarding gender, age group, marital status, employment status, household annual income, and income change during the COVID-19 pandemic considering changes in both the importance and precedence of diet. Those who were in the "worsening tendency" group in both the importance and precedence were men, 20-29 years old, unmarried, full-time employees, with a household income of 4-6 million yen during the past year.Conclusion　During the COVID-19 pandemic, the precedence of diet worsened, compared to its importance, and men, young, or unmarried persons show a worsening of dietary consciousness.

Spatial clustering of suicide mortality and associated community characteristics in Kanagawa prefecture, Japan, 2011-2017.

BACKGROUND: Suicide mortality is high in Japan and early interventional strategies to solve that problem are needed. An accurate evaluation of the regional status of current suicide mortality would be useful for community interventions. A few studies in Kanagawa prefecture, located next to Tokyo and with the second largest population in Japan, have identified spatial clusters of suicide mortality at regional levels. This study examined spatial clustering and clustering over time of such events using spatial data from regional statistics on suicide deaths. METHODS: Data were obtained from regional statistics (58 regions in Kanagawa prefecture) of the National Vital Statistics of Japan from 2011 to 2017. The standardized mortality ratio (SMR) and Empirical Bayes estimator for the SMR (EBSMR) were used as measures. Spatial clusters were examined by Kulldorff's circular spatial scan statistic, Tango-Takahashi's flexible spatial scan statistic and Tango's test. Linear regression and conditional autoregressive (CAR) models were used not only to adjust for covariates but also to estimate regional effects. The analyses were conducted for each year, inclusive. RESULTS: Among male suicide deaths, being unemployed (50%) was most frequently related to suicide while among female health problem (50%) were frequent. Spatial clusters with significance detected by FlexScan, SatScan and Tango's test were few and varied somewhat according to the method used. Spatial clusters were detected in some regions including Kawasaki ward after adjustment by covariates. By the linear regression models, selected variables with significance were different between the sexes. For males, unemployment, family size, and proportion of higher education were detected for several of the years studied while for females, family size and divorce rate were detected over this period. These variables were also observed by the CAR model with 5 covariates. Regional effects were much clearer by considering the spatial parameter for both males and females and especially, Kawasaki ward was detected as a high risk region in many years. CONCLUSION: The present results detected some spatial clustering of suicide deaths within certain regions. Factors related to suicide deaths were also indicated. These results would provide important information in policy making for suicide prevention.

Newspaper coverage before and after the HPV vaccination crisis began in Japan: a text mining analysis.

BACKGROUND: The human papillomavirus (HPV) vaccination coverage rate has fallen sharply in Japan since 2013, when newspapers began covering negative campaigns against the vaccination. We examined and compared contents from newspaper articles before and after the start of this HPV vaccination crisis. METHODS: We collected articles published between January 2005 and September 2017 in the four daily national Japanese newspapers with the highest domestic circulation. We then conducted text mining analysis to chronologically examine content distribution. RESULTS: From among the 1178 articles analyzed, 12 types of contents were identified. Contents related to cervical cancer prevention, such as on the risk of developing cervical cancer, causes of cervical cancer, and the effects of vaccination, were frequently conveyed until 2012. However, after March 2013, they were replaced with anti-vaccination contents, such as on adverse effects to vaccines, alleged victims, and related lawsuits. Meanwhile pro-vaccination contents, such as safety statements from the World Health Organization, scarcely received coverage. CONCLUSIONS: Newspaper contents changed profoundly before and after the start of the vaccination crisis. Those newspaper reports potentially had impact on readers' beliefs and actions. Journalists should strive for impartial coverage so readers can make more-informed decisions. Health professionals should be expected to work with journalists to help improve impartiality in newspaper coverage. The Ministry of Health, Labour and Welfare should discus benefits and risks of the HPV vaccination based on the scientific evidences, and consider to resume the proactive recommendation of HPV vaccination. Well-organized advocacy among medical societies, scientists and health professionals will also be needed to influence the government.

Japanese anti- versus pro-influenza vaccination websites: a text-mining analysis.

Anti-vaccination sentiment exists worldwide and Japan is no exception. Health professionals publish pro-influenza vaccination messages online to encourage proactive seeking of influenza vaccination. However, influenza vaccine coverage among the Japanese population is less than optimal. The contents of pro- and anti-influenza vaccination websites may contribute to readers' acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing content on websites for and against influenza vaccination. We conducted online searches in January 2017 using two major Japanese search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as 'pro', 'anti' or 'neutral' depending on their claims, with author(s) classified as 'health professionals', 'mass media' or 'laypersons'. Text-mining analysis was conducted, and statistical analysis was performed using a chi-squared test. Of the 334 websites analyzed, 13 content topics were identified. The three most frequently appearing content topics on pro-vaccination websites were vaccination effect for preventing serious cases of influenza, side effects of vaccination, and efficacy rate of vaccination. The three most frequent topics on anti-vaccination websites were ineffectiveness of influenza vaccination, toxicity of vaccination, and side effects of vaccination. The main disseminators of each topic, by author classification, were also revealed. We discuss possible tactics of online influenza vaccination promotion to counter anti-vaccination websites.

[Transparency in relations between multinational R&D pharmaceutical companies' corporate social responsibility activities and patient organizations in the Europe, Japan, and the United States].

Objectives　Multinational R&D pharmaceutical companies operating in many countries and regions have deep ties with patient groups that are recipients of their corporate social responsibility (CSR). CSR activities are diverse and range from direct funding (including donations and sponsorships) to indirect funding (such as expenses associated with company-sponsored lectures); there are rewards for CSR requests for patient groups (writing, supervision, and surveys), and labor is provided by company employees. In developing pharmaceutical products, R&D companies can provide greater benefits to patients by listening to them. It is therefore important for all stakeholders to ensure transparency regarding the relationship between companies and patient groups. This study aimed to identify trends in information disclosure toward ensuring transparency of relations between CSR activities and patient groups based on industry groups regulations in Japan, the United States, and Europe.Methods　The contents described in regulations by the European Federation of Pharmaceutical Industries and Associations (EFPIA), Pharmaceutical Research and Manufacturers of America (PhRMA), and the Japan Pharmaceutical Manufacturers Association (JPMA) concerning such transparency were qualitatively and inductively analyzed in terms of four concepts: transparency, equal partnership, mutual benefit, and independence.Results　Most of the descriptions relate to transparency. The EFPIA regulation is the most detailed; it states that there should be no influence on patient groups' work or on events and activities organized by companies or patient groups. The rules of the three associations also impose the need to maintain records concerning the purpose and contents of financial support and activity items. However, information disclosure to secure transparency is not required in the PhRMA regulation. The JPMA regulation does not specify a clear update schedule; the EFPIA regulation requires disclosure information to be updated once a year. In terms of equal partnership, such terms as "mutual respect," "equal value," and "establishing a trust relationship" appeared in searches with all three regulations. None of the regulations referred to "mutual benefit." All the regulations either respected or validated the independence of patient groups.Conclusion　Each pharmaceutical association set its own regulations and recommended voluntary information disclosure by member companies; however, the extent of such disclosure differed with each association. The regulations of industry associations form the basis for the policies of member companies; thus, it is desirable that the contents and regulations related to mutual information disclosure be established in great detail worldwide.

Investigation of suitable illustrations in medical care.

Visual representation methods have long been used as tools to communicate information in health education settings, and their effect on improving health literacy has been investigated. The question arises: How should an illustration function in relation to the textual information it illustrates? Medical illustrations are likely to be featured in media such as brochures and textbooks. If the textual information in such materials is so complex, what function should illustrations play? We reviewed the sociological literature on illustrations to obtain findings potentially applicable to health education and the improvement of health literacy. We then evaluated these tools to determine the types of illustrations that are suitable for the information. Of the three topics for which we developed the materials-cancer, food allergies and HEV light-only for the HEV light topic were earlier findings replicated. One key factor behind this result was that the illustrations for the HEV topic underwent a more thorough deliberative process than those for the other two topics. The results of our study also highlight the importance of third-party opinion in the illustration design process.

Improving health literacy in a Japanese community population-A pilot study to develop an educational programme.

OBJECTIVE: Although a growing number of interventional studies on health literacy have been conducted recently, the majority were designed in clinical settings, focusing mainly on functional health literacy. This study evaluated a programme designed to improve health literacy in a community population, with a scope of going beyond functional health literacy. METHODS: In collaboration with an Approved Specified Nonprofit organization (NPO), we evaluated a five-session programme designed to provide basic knowledge on health-care policy and systems, current issues in health care in Japan, patient roles and relationships with health-care providers and interpersonal skills. In total, 67 of 81 programme participants agreed to participate in the study, and 54 returned the completed questionnaires at baseline and at follow-up. Health literacy and trust in the medical profession were measured at baseline and at follow-up. Participants' learning through the programme was qualitatively analysed by thematic analysis. RESULTS: Quantitative examinations of the changes in health literacy and degree of trust in medical professionals between the baseline and follow-up suggested that health literacy significantly improved after implementing the programme. The thematic analysis of participants' learning throughout the programme suggested that they not only acquired knowledge and skills but also experienced a shift in their beliefs and behaviours. DISCUSSION: Providing individuals who are motivated to learn about health-care systems and collaborate with health-care providers with the necessary knowledge and skills may improve their health literacy, which could enable them to maintain and promote their health and that of their family and other people around them.

Reliability and validity of a 12-item medication adherence scale for patients with chronic disease in Japan.

BACKGROUND: To improve and support medication adherence among patients with chronic diseases, especially for long-term medication, it is important to consider both their relationship with healthcare providers and their lifestyle. We tested the reliability and validity of a modified 12-item Medication Adherence Scale. METHODS: We revised a 14-item measure of medication adherence, created in 2009, to a more concise and clear 12-item version, and we verified the reliability and validity of the 12-item scale. We included 328 patients with chronic diseases participating in the Chronic Disease Self-Management Program in Japan from 2011 to 2014. Confirmatory factor analysis was used to assess whether the four factors assessed were the same as the previous 14-item Medication Adherence Scale. Cronbach's coefficient alpha was used to assess internal consistency reliability, and the relationships between patient demographic characteristics and medication adherence were compared with previous studies. RESULTS: The 12 items were categorized into the four factors "medication compliance", "collaboration with healthcare providers", "willingness to access and use information about medication", and "acceptance to take medication and how taking medication fits patient's lifestyle". Confirmatory factor analysis showed χ2/df = 2.6, CFI = 0.94, and RMSEA = 0.069. Cronbach's alpha for the 12-item scale was 0.78. Cronbach's alpha for the four subscales was 0.74, 0.81, 0.67, and 0.45. Higher medication adherence was significantly associated with being a female patient, living with someone else, and age 40-49 years versus age 20-29 years. These relationships were the same as in previous studies. CONCLUSIONS: We modified our original 14-item scale to a 12-item Medication Adherence Scale for patients with chronic diseases, which considers their relationship with healthcare providers and lifestyle. Refinement might be needed because of the relatively low reliability of subscales. However, the modified scale is expected to contribute to more effective self-management of medication and to improving medication adherence, particularly among patients with chronic diseases who require long-term medication not only in Japan but also in other countries.

Changes in patient-centered attitude and confidence in communicating with patients: a longitudinal study of resident physicians.

BACKGROUND: Patient-centered care has been one of the most frequently discussed principles in medical practice. However, there is a serious concern that the patient-centered attitudes of physicians diminish over the course of their medical education. This longitudinal study examined changes in resident physicians' patient-centered attitudes and their confidence in communicating with patients, and explored the relationship between the two traits. METHODS: The study participants were resident physicians at a university hospital in Tokyo. Participants' patient-centered attitudes (as measured by the Patient-Practitioner Orientation Scale [PPOS]), and their confidence in communicating with patients (as per the Physician Confidence in the Medical Interview scale: [PCMI]) were assessed through self-reported questionnaires completed at the beginning of residency (n = 204) and again at the end of the first year (n = 95). RESULTS: PPOS scores declined significantly during the year, both in terms of attitude toward sharing information and decision-making with patients, and attitude of caring for patients' expectations and emotions. The shift in caring attitude differed significantly by gender. The increase in PCMI score was greater for those with a smaller decrease in PPOS score. CONCLUSIONS: As seen in previous studies of medical students, resident physicians' patient-centered attitudes declined during their first year of residency, while there may be a gender-based difference within the shift. The increase in physicians' confidence in communicating with patients was greater for those who showed a smaller decline in patient-centered attitude. Additional studies are needed to detail the changes in physicians' attitudes, confidence, and communication skills over the course of their medical training, and to develop systematic assessment and training programs.

Processing fluency effect of a leaflet for breast and cervical cancer screening: a randomized controlled study in Japan.

Processing fluency (the inferred subjective ease with which people process information) has been a topic of increasing research attention in the field of psychology over the past decade. We examined the effect of improving written materials in terms of processing fluency with regard to encouragement for obtaining breast and cervical cancer screening. We randomly assigned 670 women to intervention or control conditions; the 215 who mailed back distributed questionnaires were the study participants. A standard leaflet for cancer screening was mailed to the control group, while the materials mailed to the intervention group were improved in terms of perceptual fluency (e.g., legibility), linguistic fluency (e.g., readability), retrieval fluency (e.g., reducing amount of information) and imagery fluency (having recipients imagine future behavior and events). The screening rate of the intervention group was significantly higher than that of the control group (29.4% vs. 14.2%, χ2 = 7.275, df = 1, p = .007, φ = .184). Improving the processing fluency of written materials may be useful for encouraging individuals to obtain breast and cervical cancer screening.

[Content analysis of newspaper reports on passive smoking regulations in Japan].

Objectives　Ever since Tokyo was awarded the privilege to host the 2020 Olympic Games, the Japanese Ministry of Health, Labour, and Welfare has worked toward implementing a ban on passive smoking. This study examined the present situation of passive smoking in Japan, and the coverage of passive smoking regulations in newspaper reports, based on a content analysis. This was followed by a comparison with the contents of the "White Paper on Tobacco," published by the Japanese Ministry of Health, Labour, and Welfare in August, 2016.Methods　In total, 182 articles published from September 7, 2013 to March 31, 2017 were collected from three major newspapers based in Tokyo (Asahi, Yomiuri, and Mainichi). The article search criteria included the presence of the following keywords in the title or main text: "passive smoking OR entire surface smoking cessation OR indoor smoking OR indoor smoking cessation OR smoking cessation in the site OR smoking cessation in the building." Online posts and articles that did not focus mainly on the regulation of passive smoking were excluded. The 37 coding categories that were developed were classified either as positive or negative (with respect to coverage of passive smoking regulations). The assessment of passive smoking in the White Paper on Tobacco informed the coding categories, to allow the evaluation of the extent to which the contents of the White Paper were reflected in newspaper reports.Results　Among the 182 articles examined, 107 addressed only the positive aspects of the regulations, while 7 addressed only the negative aspects. Further, 50 articles addressed both positive and negative aspects, while 18 addressed neither. Among those addressing both positive and negative aspects, 14 (28%) included counterarguments to the negative comments, which consistently reflected the contents of the White Paper on Tobacco.Conclusions　Majority of the articles reported only on the positive aspects of the regulations. Persuasive articles that presented both the positive and negative aspects of the issue, which included counterarguments to the negative opinions, were scarce. However, such articles were found to some degree in the editorials of newspapers. The influence of such editorials may increase if newspapers include the pros or cons of this issue, and present counterarguments. Additionally, some topics were not reported sufficiently. Thus, problems were observed in the newspaper reports regarding passive smoking regulations.

The information-giving skills of resident physicians: relationships with confidence and simulated patient satisfaction.

BACKGROUND: Sharing information is crucial for discussion of problems and treatment decision making by patients and physicians. However, the focus of communication skills training in undergraduate medical education has been on building the relationship and gathering information; thus, resident physicians tend to be less confident about sharing information and planning treatment. This study evaluated the medical interviews conducted by resident physicians with a focus on information giving, and investigated its relationships with their confidence in communication and simulated patient (SP) satisfaction. METHODS: Among 137 junior resident physicians at a university hospital in Japan who participated in a survey of communication skills, 25 volunteered to conduct simulated medical interviews. The medical interviews were video-recorded and analyzed using the Roter Interaction Analysis System, together with additional coding to explore specific features of information giving. The SPs evaluated their satisfaction with the medical interview. RESULTS: Resident physicians who were more confident in their communication skills provided more information to the patients, while SP satisfaction was associated only with patient-prompted information giving. SPs were more satisfied when the physicians explained the rationales for their opinions and recommendations. CONCLUSION: Our findings underscore the importance of providing relevant information in response to the patient requests, and explaining the rationales for the opinions and recommendations. Further investigation is needed to clinically confirm our findings and develop an appropriate communication skills training program.
