Patients' perceptions of patient-centered communication with healthcare providers and associated factors in Japan - The INFORM Study 2020

OBJECTIVE

To describe patients' perceptions of the patient-centeredness of their communication with healthcare providers in Japan, and to examine factors associated with these perceptions.

METHODS

We analyzed the cross-sectional data from the INFORM Study 2020, which is a nationwide survey on health information access in Japan. A total of 3605 respondents completed the survey. Our primary outcome was the nine elements of the patient-centered communication scale (PCCS), which was compiled from 2703 respondents (75.0%) reporting at least one provider visit within 12 months. It was rated on a four-point Likert scale: always, usually, sometimes, and never. We used binary logistic regression to examine the association between sociodemographic and health-related variables, and each element of the PCCS.

RESULTS

For all elements, the percentage of respondents who agreed that their healthcare providers always communicated in a patient-centered way was low (17-31%). Patients with higher age, higher education, poorer general health status and a larger number of visits to providers in the previous 12 months were more likely to have positive perception.

CONCLUSION

Patient-centered communication as reported in a national sample in Japan was low.

CLINICAL IMPLICATIONS

Efforts are needed to improve the patient-centeredness of patient-provider communication in Japan to optimize health outcomes.

Trust in Mass Media as Sources of Cancer Information: Findings from a Nationally Representative Cross-Sectional Survey in Japan

Trust is a major factor in effective public dissemination and use of relevant health information to guide important health decisions. To examine mass media as a communication channel for delivering cancer information among Japanese adults, we identified the level of trust in various types of mass media as sources of cancer information, and examined factors associated with trust, including exposure to mass media, sociodemographic factors, and cancer history. Data were analyzed for 3,109 Japanese adults who responded to a nationally representative cross-sectional mail survey. Data included trust in cancer information sources, sociodemographic variables, cancer history, and exposure to mass media. Logistic regression analysis was used. The prevalence of high trust in cancer information sources was highest for physicians (94.7%). Among mass media, Internet (47.2%) was the most trusted source of cancer-related information, followed by television (44.3%), newspapers/magazines (42.7%), and radio (32.7%). The high-exposure group for newspapers (AOR = 1.28, 95%CI = 1.07-1.54) was more likely to trust newspapers. Similarly, high-exposure groups for radio (1.22, 1.02-1.45), Internet (1.21, 1.01-1.45), and television (1.30, 1.10-1.53) were positively associated with trust in each media type. Although trust in mass media was lower than trust in physicians, the study found that a large group of respondents had high levels of trust in mass media sources. Trust in cancer information from each mass media type was mainly related to the level of exposure to each mass media type. Developing health communication strategies using mass media may be effective for disseminating relevant cancer information in Japan.

Associations of individual characteristics and socioeconomic status with heated tobacco product harmfulness perceptions in Japan: A nationwide cross-sectional study (INFORM Study 2020)

IntroductionIn Japan, heated tobacco products (HTPs) are promoted by the tobacco industry as reduced-risk tobacco products despite the lack of evidence for this claim. This study determined the distribution of HTP-harmfulness perception and identify the explanatory factors associated with the perception of HTP as less harmful than conventional cigarettes.MethodsA nationwide cross-sectional survey was conducted with Japanese people aged 20 years or older (INFORM Study 2020) using a self-administered questionnaire. We performed descriptive analysis and weighted logistic regression analysis to examine the relationship between explanatory factors (e.g., individual characteristics, socioeconomic status, and trusted sources of cancer information) and the perception of HTPs as less harmful.ResultsAmong 3,420 participants (response rate: 35.2%), the proportions of those who perceived HTPs as less harmful were 40.3% and 18.3% for users and non-users of tobacco, respectively. For participants aged 20-39 years, the proportion were 49.9% and 30.4%, respectively. Among 1,160 non-tobacco users who were familiar with HTPs, male, aged under 39 years, and had lower education were associated with the perception of HTPs as less harmful. Trusted sources of cancer information were not associated with the perception of HTPs as less harmful.ConclusionsThis study showed that, among non-tobacco users, being male, aged under 39 years, and lower education were associated with a perception of HTPs as less harmful. Public health stakeholders should provide the latest evidence about HTP harmfulness in their daily practice, and strengthen the regulations on HTP marketing directed at both tobacco- and non-tobacco users.

Age, gender and socioeconomic disparities in human papillomavirus (HPV) awareness and knowledge among Japanese adults after a 7-year suspension of proactive recommendation for the HPV vaccine: A nationally representative cross-sectional survey

The Japanese government's 2013 suspension of its proactive recommendation for Human papillomavirus (HPV) vaccination resulted in low HPV vaccination coverage and was unique. However, data on awareness and knowledge of HPV vaccines in the general population was limited. Here, to investigate more recent awareness and knowledge of HPV vaccines by age, gender, and socioeconomic status, we used data from the INFORM Study 2020, a nationally representative cross-sectional survey of self-administered questionnaires with 1,998 Japanese individuals aged 20 to 59 years. We found that 47.5% of females and 21.0% of males had heard of HPV, and 33.6% of females and 16.8% of males had knowledge of HPV vaccine efficacy. After adjusting for potential confounders, females aged 50-54 years were more likely to be aware of HPV than females aged 20-24 (AOR, 2.02, 95%CI: 1.12-3.65). Females (AOR, 2.13, 95%CI: 1.48-3.07) and males (AOR, 1.64, 95%CI: 1.03-2.59) with higher education had more awareness than those with less education. Females with higher education had more knowledge about HPV vaccine efficacy than those with less education (AOR, 1.70; 95%CI: 1.16-2.50). We found a generally low level of awareness and knowledge about HPV vaccines in Japan, which might be attributable to the suspension of proactive recommendations. Additionally, we identified disparities in awareness and knowledge by age, gender, socioeconomic status, and health literacy. Enhancing HPV awareness and understanding of HPV vaccines and implementing targeted efforts for specific subpopulations within Japan after the resumption of proactive recommendation for HPV vaccines, are imperative.

Barriers and facilitators to implementing geriatric assessment in daily oncology practice in Japan: A qualitative study using an implementation framework

INTRODUCTION

Various guidelines recommend geriatric assessment (GA) for older adults with cancer, but it is not widely implemented in daily practice. This study uses an implementation framework to comprehensively and systematically identify multi-level barriers and facilitators to implementing GA in daily oncology practice.

MATERIALS AND METHODS

We conducted 16 semi-structured interviews with healthcare providers in 10 designated cancer hospitals in Japan, using purposive and convenience sampling. The Consolidated Framework for Implementation Research (CFIR) was used to guide collection and analysis of interview data following a deductive content analysis approach with consensual qualitative research methods. After coding the interview data, ratings were assigned to each CFIR construct for each case, reflecting the valence and strength of each construct relative to implementation success. Then, those constructs that appeared to distinguish between high-implementation hospitals (HI) where GA is routinely performed in daily practice and low-implementation hospitals (LI) where GA is performed only for research purposes or not at all were explored.

RESULTS

Of the 24 CFIR constructs assessed in the interviews, 15 strongly distinguished between HI and LI. In HI, GA was self-administered (Adaptability), or administered via a mobile app with interpretation (Design Quality and Packaging). In HI, healthcare providers were strongly aware of the urgent need to change practice for older adults (Tension for Change) and recognized that GA was compatible with existing workflow as part of their jobs (Compatibility), whereas in LI, they did not realize the need to change practice, and dismissed GA as an extra burden on their heavy workload. In HI, usefulness of GA was widely recognized by healthcare providers (Knowledge & Beliefs about the Intervention), GA had a high priority (Relative Priority) and had strong support from hospital directors, managers, and nursing chiefs (Leadership Engagement), and multiple stakeholders were successfully engaged, including nurses (Key Stakeholders), peer doctors (Opinion Leaders), and those who drive implementation of GA (Champions).

DISCUSSION

These findings suggest that successful implementation of GA should focus on not only individual beliefs about the usefulness of GA and the complexity of GA itself, but also organizational factors related to hospitals and the engagement of multiple stakeholders.

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.

Screening practices of cancer survivors and individuals whose family or friends had a cancer diagnoses-a nationally representative cross-sectional survey in Japan (INFORM Study 2020)

PURPOSE

We examined cancer screening practices and related beliefs in cancer survivors and individuals with family or close friends with a cancer diagnosis compared to individuals without the above cancer history for 5 population-based (gastric, colorectal, lung, breast, cervical) and 1 opportunistic (prostate) cancer screenings using nationally representative cross-sectional survey in Japan.

METHODS

We analyzed 3269 data from 3605 respondents (response rate, 37.1%) and compared the screening beliefs and practices of cancer survivors (n = 391), individuals with family members (n = 1674), and close friends with a cancer diagnosis (n = 685) to those without any cancer history (n = 519).

RESULTS

Being a cancer survivor was associated with screening for gastric (OR, 1.75; 95% CI, 1.04-2.95), colorectal (OR, 1.56; 95% CI, 1.03-2.36), and lung cancer (OR, 1.71; 95% CI, 1.10-2.66) but not breast, cervical cancer or PSA test. Having a family cancer diagnosis was associated with colorectal and lung cancer screening. Having friends with a cancer diagnosis was associated with PSA test. Cancer survivors and family members perceived themselves as being more susceptible and worried about getting cancer than individuals without any cancer history. Cancer survivors strongly believed screening can detect cancer and were more likely to undergo screening. Subgroup analysis indicated an interrelation between gastric and colorectal cancer screening among survivors.

CONCLUSIONS

A cancer diagnosis in oneself or family or friend influences an individual's health-related belief and risk perception, which can increase the likelihood of cancer screening.

IMPLICATIONS FOR CANCER SURVIVORS

Targeted and tailored communication strategies can increase awareness of cancer screening.

Chronic Diseases and Sociodemographic Characteristics Associated With Online Health Information Seeking and Using Social Networking Sites: Nationally Representative Cross-sectional Survey in Japan

BACKGROUND

In an aging society, worsening chronic diseases increase the burden on patients and the health care system. Using online health information including health information via social networking sites (SNSs), such as Facebook and YouTube, may play an important role in the self-management of chronic diseases and health promotion for internet users.

OBJECTIVE

This study aims to improve strategies for promoting access to reliable information for the self-management of chronic diseases via the internet, and to identify populations facing barriers to using the internet for health, we examined chronic diseases and characteristics associated with online health information seeking and the use of SNSs.

METHODS

This study used data from the INFORM Study 2020, which was a nationally representative cross-sectional postal mail survey conducted using a self-administered questionnaire in 2020. The dependent variables were online health information seeking and SNS use. Online health information seeking was assessed using 1 question about whether respondents used the internet to find health or medical information. SNS use was assessed by inquiring about the following 4 aspects: visiting SNSs, sharing health information on SNSs, writing in an online diary or blog, and watching a health-related video on YouTube. The independent variables were 8 chronic diseases. Other independent variables were sex, age, education status, work, marital status, household income, health literacy, and self-reported health status. We conducted a multivariable logistic regression model adjusted for all independent variables to examine the associations of chronic diseases and other variables with online health information seeking and SNS use.

RESULTS

The final sample for analysis comprised 2481 internet users. Hypertension or high blood pressure, chronic lung diseases, depression or anxiety disorder, and cancer were reported by 24.5%, 10.1%, 7.7%, and 7.2% of respondents, respectively. The odds ratio of online health information seeking among respondents with cancer was 2.19 (95% CI 1.47-3.27) compared with that among those without cancer, and the odds ratio among those with depression or anxiety disorder was 2.27 (95% CI 1.46-3.53) compared with that among those without. Further, the odds ratio for watching a health-related YouTube video among those with chronic lung diseases was 1.42 (95% CI 1.05-1.93) compared with that among those without these diseases. Women, younger age, higher level of education, and high health literacy were positively associated with online health information seeking and SNS use.

CONCLUSIONS

For patients with cancer, strategies for promoting access to websites with reliable cancer-related information as well as access among patients with chronic lung diseases to YouTube videos providing reliable information may be beneficial for the management of these diseases. Moreover, it is important to improve the online environment to encourage men, older adults, internet users with lower education levels, and those with low health literacy to access online health information.

Factors influencing implementation of health-promoting interventions at workplaces: Protocol for a scoping review

Introduction

Health-promoting interventions at workplaces can be effective in modifying lifestyle-related behavioral risk factors for non-communicable diseases (NCDs). However, the interventions are not always successful in the real-world setting, and the evidence for effective strategies to implement the interventions has been limited. We propose a scoping review to identify the topics in need of study and areas for future research on barriers to and facilitators of the implementation of workplace health-promoting interventions.

Materials and methods

This scoping review will explore these issues from the perspective of supply-side stakeholders, who have a direct role in the implementation of these interventions. An electronic systematic search of MEDLINE (using PubMed), Web of Science, and Scopus databases from 1986 to 2022, in accordance with the PRISMA-ScR guidelines, will be performed. Supplementary hand searching will be undertaken with reference lists from included articles and consulting with relevant stakeholders. Two authors will be responsible for individually screening the corresponding articles by first reading the titles and abstracts and then the full texts to assess whether they meet the inclusion criteria. Data extraction will be conducted using standardized data collection forms, and data analysis will be aligned to the consolidated framework for implementation research (CFIR), a determinant framework of factors affecting implementation, using a directed content analysis approach.

Discussion

We will present the findings from this review at national and international conferences and submit them to a peer-reviewed journal for publication. Future workplace interventions will significantly benefit from this comprehensive scoping review to identify factors that enable improvement of the implementation, and the barriers to improvement, of evidence-based health-promoting interventions at workplaces.

Using implementation mapping to develop strategies for preventing non-communicable diseases in Japanese small- and medium-sized enterprises

Introduction

Workplace programs to prevent non-communicable diseases (NCDs) in the workplace can help prevent the incidence of chronic diseases among employees, provide health benefits, and reduce the risk of financial loss. Nevertheless, these programs are not fully implemented, particularly in small- and medium-sized enterprises (SMEs). The purpose of this study was to develop implementation strategies for health promotion activities to prevent NCDs in Japanese SMEs using Implementation Mapping (IM) to present the process in a systematic, transparent, and replicable manner.

Methods

Qualitative methods using interviews and focus group discussions with 15 SMEs and 20 public health nurses were conducted in a previous study. This study applied the Consolidated Framework for Implementation Research and IM to analyze this dataset to develop implementation strategies suitable for SMEs in Japan.

Results

In task 2 of the IM, we identified performance objectives, determinants, and change objectives for each implementation stage: adoption, implementation, and maintenance; to identify the required actors and actions necessary to enhance implementation effectiveness. Twenty-two performance objectives were identified in each implementation stage. In task 3 of the IM, the planning group matched behavioral change methods (e.g., modeling and setting of graded tasks, framing, self-re-evaluation, and environmental re-evaluation) with determinants to address the performance objectives. We used a consolidated framework for implementation research to select the optimal behavioral change technique for performance objectives and determinants and designed a practical application. The planning team agreed on the inclusion of sixteen strategies from the final strategies list compiled and presented to it for consensus, for the overall implementation plan design.

Discussion

This paper provides the implementation strategies for NCDs prevention for SMEs in Japan following an IM protocol. Although the identified implementation strategies might not be generalizable to all SMEs planning implementation of health promotion activities, because they were tailored to contextual factors identified in a formative research. However, identified performance objectives and implementation strategies can help direct the next steps in launching preventive programs against NCDs in SMEs.

Factors affecting the implementation of guideline-based prophylactic antiemetic therapy for chemotherapy-induced nausea and vomiting in Japan: a protocol for a hospital-based qualitative study

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) decrease patients' quality of life and negatively impact treatment outcomes. Although standard prophylactic antiemetic therapy for acute CINV recommended by guidelines is effective, poor guideline implementation is a worldwide problem. In Japan, prophylactic antiemetic therapy is relatively well implemented for chemotherapy associated with high emetogenic risk, while implementation gaps are observed for that with low emetogenic risk.Although most reports on factors influencing appropriate antiemetic prescription focus on physicians' attitudes and behaviours, a more comprehensive exploration is needed since chemotherapy is expected to involve pharmacists, nurses and eventually hospital directors. The purpose of this qualitative study is to comprehensively explore the factors that influence the implementation of appropriate prophylactic antiemetic procedures at cancer care hospitals in Japan.

METHODS AND ANALYSIS

This study is a hospital-based qualitative study using semistructured individual interviews. The target population will be hospital directors, and chiefs (including proxies) of departments of oncology and/or chemotherapy, pharmacy and nursing, working in the hospitals, selected by purposive sampling. We will obtain information on antiemetics in chemotherapy regimens, antiemetic routine use and awareness of guidelines using prequestionnaires. Interviews will then be conducted online using an interview guide. The Consolidated Framework for Implementation Research will be used to collect and analyse the interview data. We will also create new codes inductively, as required. In addition, we will refer to the aggregate results of the Quality Indicator survey to determine the implementation of recommended antiemetic prescriptions for each hospital and discuss the relationship with influencing factors.

ETHICS AND DISSEMINATION

This study has been approved by the National Cancer Centre Ethics Approval Committee (approval number: 2020-305). The study findings will be disseminated via peer-reviewed journal publications and presentations to academics, policy-makers, and clinicians at scientific conferences.

Barriers and facilitative factors in the implementation of workplace health promotion activities in small and medium-sized enterprises: a qualitative study

Background

There is an immense difference between large companies and small and medium-sized enterprises (SMEs) in implementation of evidence-based interventions (EBIs). Previous literature reveals various barriers that SMEs face during implementation, such as a lack of time, accessibility, and resources. However, few studies have comprehensively examined those influential factors at multi-levels. This study aims to identify the factors influencing the implementation of non-communicable disease prevention activities (tobacco, alcohol, diet, physical activity, and health check-up) in SMEs using Consolidated Framework for Implementation Research (CFIR).

Methods

We conducted 15 semi-structured interviews with health managers and/or employers in 15 enterprises with less than 300 employees, and four focus groups among public health nurses/nutritionists of health insurers who support SMEs in four prefectures across Japan. A qualitative content analysis by a deductive directed approach was performed. After coding the interview transcript text into the CFIR framework constructs by two independent researchers, the coding results were compared and revised in each enterprise until an agreement was reached.

Results

Of the 39 CFIR constructs, 25 were facilitative and 7 were inhibitory for workplace health promotion implementation in SMEs, which were across individual, internal, and external levels. In particular, the leadership engagement of employers in implementing the workplace health promotion activities was identified as a fundamental factor which may influence other facilitators, including “access to knowledge and information,” “relative priority,” “learning climate,” at organizational level, and “self-efficacy” at the health manager level. The main barrier was the beliefs held by the employer/manager that “health management is one’s own responsibility.”

Conclusions

Multi-level factors influencing the implementation of non-communicable diseases prevention activities in SMEs were identified. In resource-poor settings, strong endorsement and support, and positive feedback from employers would be important for health managers and employees to be highly motivated and promote or participate in health promotion. Future studies are needed to develop context-specific strategies based on identified barriers and facilitative factors, and empirically evaluate them, which would contribute to narrowing the differences in worksite health promotion implementation by company size.

Barriers and facilitators of geriatric assessment implementation in daily oncology practice: A qualitative study applying a theoretical implementation framework

12012

Background: Geriatric assessment (GA) is recommended in various guidelines for older adults with cancer, but is not widely used in daily practice. This study aims to identify multi-level barriers and facilitators of GA implementation in daily oncology practice, based on a theoretical implementation framework. Methods: We conducted 20 semi-structured interviews with healthcare providers and managers in 14 hospitals treating older adults with cancer in Japan. The Consolidated Framework for Implementation Research (CFIR) was used to guide the collection and analysis of interview data using a deductive approach. CFIR consists of 5 major domains (I. intervention characteristics, II. outer setting, inner setting,. individual characteristics, and V. process), including 39 constructs. Differences in the constructs influencing GA implementation between hospitals where GA is routinely performed (high implementation, HI) and hospitals where GA is not performed or performed only in clinical trials (low implementation, LI) were explored. Results: Among constructs identified as barriers or facilitators of GA implementation, 15 multi-level constructs greatly differed between 5HI and 5LI, including 4 constructs from intervention characteristics, 6 from inner setting, 1 from individual characteristics, and 4 from process. In HI, GA was self-administered (I. adaptability), or administered on a mobile app with interpretation (I. design quality and packaging). In HI, healthcare providers strongly perceived the need to change the practice for older adults (III. tension for change), and recognized GA as fitting in with existing workflow as part of their jobs (III. compatibility). In LI, they did not realize the need to change practice, and rejected GA as an extra burden on their heavy workload. In HI, the usefulness of GA was widely recognized by healthcare providers (IV. knowledge and beliefs about the intervention), GA was given high priority (III. relative priority), had strong support from hospital directors and nursing chiefs (V. leadership engagement), and multiple stakeholders were successfully engaged, such as healthcare providers, especially nurses (V. key stakeholders), directors and nursing chiefs (V. opinion leaders), and those who dedicated themselves to implementing GA (champions). Conclusions: This is the first study to reveal the multi-level barriers and facilitators of GA implementation in daily oncology practice. The findings highlight the need to focus not only on individual or intervention characteristics, but also on the inner setting and the process of implementing GA. Our findings suggest future strategies, such as devising the administration of GA using technology, conducting local needs assessment and consensus discussions about the usefulness and priority of GA, and engaging multiple stakeholders.

Evaluation of rapid drug safety communication materials for patients in Japan

Since 2011, pharmaceutical companies in Japan have been required to issue two types of documents regarding severe adverse drug reactions reported post-marketing, namely the Rapid Safety Communication Materials for Patients and the Related Materials. However, the adequacy of these documents has not yet been systematically assessed. The aim of this study was to evaluate the adequacy of these two types of materials. The Rapid Safety Communications for Patients were obtained from the Pharmaceuticals and Medical Devices Agency (PMDA) website. The Related Materials were obtained from pharmaceutical companies or the PMDA website. Three assessors independently scored the Rapid Safety Communication for Patients and the Related Materials using the Centers for Disease Control and Prevention Clear Communication Index (CCI). In addition, the contents and descriptions of the materials were analyzed. In total, 13 materials for seven drugs were assessed. Almost all materials contained the "main message" and "call to action". However, the average CCI scores for the Rapid Safety Communication for Patients and Related Materials for Patients were 68.8 and 74.3 (out of 100), respectively. Further, none of the evaluated materials were scored above the CCI threshold score (i.e., ≥ 90%). Descriptions regarding "language", "state of science", and "risk" were not adequate. In particular, the terminology used in materials seemed difficult for patients to understand. In conclusion, the Japanese Rapid Communication Materials for Patients require improvement. Furthermore, a system for evaluating these materials prior to publication should be established.

Validation of the Japanese Transition Readiness Assessment Questionnaire

BACKGROUND

For patients with childhood-onset chronic illnesses, the transition to adult care requires an understanding of transition readiness and the effectiveness of evaluation methods. However, no such psychometrically verified scales exist in Japan. This study aimed to develop a Japanese version of the Transition Readiness Assessment Questionnaire (TRAQ) and verify its validity and reliability.

METHODS

The Japanese TRAQ was developed in accordance with international guidelines, followed by a preliminary survey to verify face validity among six participants who fulfilled the inclusion criteria. For the main survey 107 patients who fulfilled the same inclusion criteria were asked to complete the questionnaire and provide basic information. After descriptive statistics analysis, the construct validity of the Japanese TRAQ was tested using the t-test and Pearson's correlation coefficients. Cronbach's alpha coefficients were calculated to assess reliability.

RESULTS

In the main survey, 76 participants with no missing data were included in the complete data analysis (40 males 36 females; mean age, 17.8 and 18.2 years, respectively). The mean total Japanese TRAQ score was 3.9. Cronbach's alpha coefficients were 0.94 overall and 0.8-0.96 for each of the four domains. The known-groups analysis revealed that older participants (r = 0.23, P = 0.044), those having knowledge of the disease name (yes [4.0] vs no [3.4]; P < 0.001), and making unaccompanied hospital visits (with parent/others [3.7] vs alone [4.4]; P < 0.001) had significantly higher total TRAQ scores.

CONCLUSION

We confirmed preliminarily the validity and reliability of the Japanese TRAQ.
