Linking patient-centered communication with cancer information avoidance: The mediating roles of patient trust and literacy

OBJECTIVES

This study, drawing on the pathway mediation model developed by Street and his colleagues (2009) that links communication to health outcomes, explores how patient-centered communication affects cancer information avoidance.

METHODS

Data was gathered through online access panel surveys, utilizing stratified sampling across Germany, Switzerland, the Netherlands, and Austria. The final sample included 4910 non-cancer and 414 cancer patients, all receiving healthcare from clinicians within the past year.

RESULTS

The results demonstrated that patient-centered communication is directly associated with reduced cancer information avoidance, especially among cancer patients. Additionally, this association is indirectly mediated through patient trust and healthcare literacy.

CONCLUSION

The findings provide empirical evidence that reveals the underlying mechanism linking clinician-patient communication to patient health information behavior.

PRACTICE IMPLICATIONS

The potential of clinician-patient communication in addressing health information avoidance is highlighted by these findings. Future interventions in healthcare settings should consider adopting patient-centered communication strategies. Additionally, improving patient trust and literacy levels could be effective in reducing cancer information avoidance.

Clarifying the Relationship Between Information Seeking and Avoidance: Longitudinal Analyses of Information Behaviors and Their Normative Influences

Information seeking and avoidance are relevant behaviors to cope with health crises. While there are various assumptions about their relationship, past research has not yet analyzed their interplay. The present study aims to clarify the relationship between information seeking and avoidance in the course of the COVID-19 pandemic and shed light on whether both behaviors are impacted by seeking- and avoidance-related norms, which are known factors in individuals' health- and risk-related behaviors. Based on a four-wave panel study conducted among German residents (n = 492), we investigated information seeking and avoidance and their normative influences from a longitudinal perspective. Results of random intercept cross-lagged panel models suggest that information seeking and avoidance are distinct, not causally related but correlated concepts. This understanding is supported by the findings that seeking- and avoidance-related norms operate differently for seeking and avoidance. The results add to construct clarification and theory development, but more research is needed to understand the relations between information behaviors.

Changes in the ability to correctly identify schizophrenia and depression: results from general population surveys in Germany over 30 years

PURPOSE

This study aims to examine time trends in the ability to correctly identify schizophrenia and major depression within the German general population from 1990 to 2020, as an indicator of changing mental health literacy (MHL). Additionally, we investigated shifts in the use of stigmatizing language.

METHODS

Our analysis is based on four waves of representative population surveys in Germany in 1990/1993 (West Germany: N = 2044, East Germany: N = 1563), 2001 (N = 5025), 2011 (N = 2455), and 2020 (N = 3042) using identical methodology. Respondents were presented with an unlabelled case vignette describing a person who exhibited symptoms of either schizophrenia or major depression. Participants were then asked to name the problem described in the vignette using an open-ended question.

RESULTS

From 1990/1993 to 2020, correct identification of schizophrenia increased from 18% to 34% and from 27% to 46% for major depression. However, derogatory labels remained constant throughout all survey waves, particularly for schizophrenia (19% in 1990/1993 and 18% in 2020). For depression, more trivializing and potentially devaluing statements were recorded.

CONCLUSION

Despite the increasing use of psychiatric terminology among the general population, the persistence of derogatory labels suggests that improved MHL, reflected in higher recognition rates, may not automatically translate into a reduction in stigmatizing language. With depression, a normalization and trivialization of a severe illness could pose new challenges to people with major depression. Dedicated efforts to combat the stigma of severe mental illness are still needed.

Digital clinical empathy in a live chat: multiple findings from a formative qualitative study and usability tests

BACKGROUND

Clinical empathy is considered a crucial element in patient-centered care. The advent of digital technology in healthcare has introduced new dynamics to empathy which needs to be explored in the context of the technology, particularly within the context of written live chats. Given the growing prevalence of written live chats, this study aimed to explore and evaluate techniques of digital clinical empathy within a familial cancer-focused live chat, focusing on how health professionals can (a) understand, (b) communicate, and (c) act upon users' perspectives and emotional states.

METHODS

The study utilized a qualitative approach in two research phases. It examined the expected and implemented techniques and effectiveness of digital clinical empathy in a live chat service, involving semi-structured interviews with health professionals (n = 9), focus group discussions with potential users (n = 42), and two rounds of usability tests between health professionals (n = 9) and users (n = 18). Data were examined using qualitative content analysis.

RESULTS

Expected techniques of digital clinical empathy, as articulated by both users and health professionals, involve reciprocal engagement, timely responses, genuine authenticity, and a balance between professionalism and informality, all while going beyond immediate queries to facilitate informed decision-making. Usability tests confirm these complexities and introduce new challenges, such as balancing timely, authentic responses with effective, personalized information management and carefully framed referrals.

CONCLUSIONS

The study reveals that the digital realm adds layers of complexity to the practice of clinical empathy. It underscores the importance of ongoing adaptation and suggests that future developments could benefit from a hybrid model that integrates the strengths of both AI and human health professionals to meet evolving user needs and maintain high-quality, empathetic healthcare interactions.

Stigma and public attitudes toward euthanasia or assisted suicide for psychiatric conditions: results from a general population survey in Germany

BACKGROUND

With growing numbers of countries legalizing euthanasia or assisted suicide (EAS), there is a debate as to whether EAS should also be available to people with severe, treatment-resistant mental illness. Excluding mental illness as a legitimate reason to receive EAS has been framed as discriminating against people with mental illness.

AIMS

We examine whether approval or opposition to psychiatric EAS are related to stigma toward people with mental illness.

METHOD

We asked a representative sample of the general population in Germany (N = 1515) whether they would approve of EAS for someone with severe, treatment-resistant mental illness. Stigma was assessed with the Value-Based Stigma Inventory (VASI), addressing rejection of people with mental illness in relation to different personal values.

RESULTS

A total of 19% of the German population approved of psychiatric EAS. Higher stigma scores were associated with greater approval of EAS (Spearman rank correlation coefficient, 0.28; P < 0.001). This association held true when controlling for sociodemographic variables. It was strongest for stigma related to perceived threats to one's security, reputation and meritocratic values.

CONCLUSIONS

Our results highlight that, although opposing psychiatric EAS is sometimes framed as discriminatory, approval of psychiatric EAS might also carry hidden, stigmatising motives. To avoid any unintended negative consequences for people with severe, treatment-resistant mental illness, any legislation on psychiatric EAS needs to be crafted with particular caution.

A qualitative interview study of patients' attitudes towards and intention to use digital interventions for depressive disorders on prescription

Background

Depressive disorders are an emerging public health topic. Due to their increasing prevalence, patients with depressive disorders suffer from the lack of therapeutic treatment. Digital health interventions may offer an opportunity to bridge waiting times, supplement, or even substitute in-person treatment. Among others, the Unified Theory of Acceptance and Use of Technology (UTAUT) explains that actual technology use is affected by users' behavioural intention. However, patients' perspectives on digital interventions are rarely discussed within the specific context of primary care provided by general practitioners (GP) and need further exploration.

Method

A qualitative study design with semi-structured interviews was used to explore DTx-acceptance of patients with mild or moderate depression (n = 17). The audio-recorded interviews were transcribed verbatim, coded, and thematically analysed by qualitative content analysis.

Results

Patients' performance expectancies reveal that DTx are not perceived as a substitute for face-to-face treatment. Effort expectancies include potential advantages and efforts concerning technical, motivational, and skill-based aspects. Moreover, we identified health status and experience with depressive disorders as other determinants and potential barriers to patients' DTx acceptance: Difficult stages of depression or long-time experience are perceived hurdles for DTx use. GPs' recommendations were just partly relevant for patients and varied according to patients' consultancy preferences. But still, GPs have a crucial role for access due to prescription. GPs' influence on patients' DTx acceptance varies between three situations: (1) pre-use for consultation, (2) pre-use for access and (3) during DTx-use. Further, GPs' guidance could be especially relevant for patients during DTx-use in routine care.

Discussion

The UTAUT-based exploration suggests that acceptance determinants should be considered independently and embedded in personal and situational aspects. DTx require a healthcare professional to prescribe or diagnose the disease, unlike other digital offerings. We identified prescription- and depression-related determinants, exceeding existing theoretical constructs. GPs' guidance can compensate for some barriers to DTx use e.g., by increasing commitment and motivational support to strengthen patients' acceptance.

Conclusion

We argue for a multidimensional integration of acceptance determinants for further development of health technology acceptance research. Future research should specify how DTx can be integrated into routine care to strengthen user acceptance.

Outcomes of Information Seeking and Avoidance Behaviors: Insights from a German Longitudinal Study

Examining information behaviors is often justified by their consequences but theoretical models of information behaviors have focused on antecedents of seeking and avoidance rather than their outcomes. Therefore, the current study aims to explore the affective, cognitive, and behavioral consequences of information-seeking and avoidance behaviors related to the COVID-19 pandemic. Based on a secondary analysis of a four-wave online survey of a sample of German residents (n = 492), we conducted hybrid models allowing us to differentiate between within-person effects of information behaviors on the outcomes and between-person correlations between information behaviors and outcomes. The findings revealed only single and small effects of information behaviors. Cognitive consequences such as risk perceptions were influenced by information seeking, whereas information seeking and avoidance affected individuals' subjective but not their objective level of knowledge. Neither information seeking nor avoidance impacted affective responses or a variety of behavioral consequences. These results contrast with assumptions that information seeking is per se a desirable health outcome, whereas information avoidance might be a barrier to health prevention and pandemic containment. At least in times of a health crisis, the findings suggest that information behavior might not be the central determinant of various affective, cognitive, and behavioral outcomes.

Media Coverage of Alcohol-Use Disorders in German Newspapers and Magazines: A Topic-Specific Frame Analysis

Alcohol use disorders (AUD) are pressing social problems. News media play a key role in setting the agenda for the public discourse and framing these problems. They provide people affected and unaffected with health-related information on different facets of the disease and present the topic in various contexts. In doing so, they shape the public opinion and influence behaviors. On the basis of an explorative quantitative content analysis of N = 402 articles published in 2019 in nine German newspapers and magazines, this study provides information on the topic-specific framing with regard to AUD. The results show only scant contextualization of the topic in the German media. This deficiency has particular regard to causal relationships and treatment opportunities, leaving room for interpretation from the audience. The topic-specific framing analysis showed that articles on AUD mostly appear either in the context of celebrities, endorsing favorable presentations of recovered people, or in the context of crime and violence, which goes hand in hand with portraying acutely affected people as perpetrators. Increased news coverage that includes the portrayal of non-famous people who have successfully engaged in alcohol treatment and recovery is necessary.

[A gendered perspective of information behaviors, its drivers, and barriers : Results of an online survey of a sample stratified for the German population]

BACKGROUND

The gender perspective is an essential level of effective health communication approaches. Against the background of the gender perspective as an essential level of effective health communication approaches, we focus on health-related information behaviors. Complementary to information seeking, information avoidance is included. Both forms of information behavior are described in gender-specific ways, and their predictors are identified using a resource-centered approach covering the individual's health, empowerment, involvement, and social support.

METHOD

An online survey of a sample stratified for the German population (N = 3000) was conducted. The two modes of information behavior as well as their theoretically derived predictors were assessed. In addition to descriptive analyses, blockwise regression analyses were used to identify gender-specific predictors of information seeking and avoidance.

RESULTS

Information seeking occurs more frequently than information avoidance. Both differ only slightly between men and women and showed the strongest correlations with the respondents' involvement. For information seeking, coping resources are also a significant predictor, while information avoidance is associated with psychological well-being and social support. Similar patterns of association emerge across genders.

CONCLUSION

Across genders, it is evident that health communication measures should strengthen the involvement of the population and their coping resources to promote information seeking and counteract information avoidance. Additionally, the findings revealed that avoiders should be more focused as one of the main target groups of health communication.

Health Information Repertoires of Implant Patients: Toward a Deeper Understanding of Multiple Source Use and the Role of Health-Related Motives

Health information-seeking behavior can be understood as an active and purposeful acquisition of information from selected information sources. It supports patients to cope with medical and health-related uncertainties and enables them to engage in informed decision-making. To obtain health information, patients can turn to a variety of sources, such as going to a physician, exchanging information with their family, or using different Internet sources. Research showed that patients typically use multiple sources to meet their health-related information needs. To attain a holistic and differentiated picture of patients' actual health information behavior, the current study draws on the repertoire approach. We conducted an online survey with 1,105 implant patients and performed a cluster analysis to explore their health information repertoires. To gain a deeper understanding of the practical meaning behind the repertoires, we also considered health-related information motives and socio-structural factors, as well as the implant type (dental, orthopedic, cochlear), to characterize the repertoires. The study revealed seven different health information repertoires of implant patients, varying in their combination of multiple sources used. In addition, group comparisons showed that the repertoires differ significantly regarding socio-structural factors, such as gender, age, and education, as well as implant type. Furthermore, information motives contribute significantly to the differentiation of the repertoires. The results are of high theoretical potential for communication science as well as practical use for strategic health communication.

Intentions of Patients With Cancer and Their Relatives to Use a Live Chat on Familial Cancer Risk: Results From a Cross-Sectional Web-Based Survey

BACKGROUND

An important prerequisite for actively engaging in cancer prevention and early detection measures, which is particularly recommended in cases of familial cancer risk, is the acquisition of information. Although a lot of cancer information is available, not all social groups are equally well reached because information needs and communicative accessibility differ. Previous research has shown that a live chat service provided by health professionals could be an appropriate, low-threshold format to meet individual information needs on sensitive health topics such as familial cancer risk. An established German Cancer Information Service is currently developing such a live chat service. As it is only worthwhile if accepted by the target groups, formative evaluation is essential in the course of the chat service's development and implementation.

OBJECTIVE

This study aimed to explore the acceptance of a live chat on familial cancer risk by patients with cancer and their relatives (research question [RQ] 1) and examine the explanatory power of factors associated with their intentions to use such a service (RQ2). Guided by the Extended Unified Theory of Acceptance and Use of Technology (UTAUT2), we examined the explanatory power of the following UTAUT2 factors: performance expectancy, effort expectancy, social influence, facilitating conditions, and habit, supplemented by perceived information insufficiency, perceived susceptibility, perceived severity, and cancer diagnosis as additional factors related to information seeking about familial cancer.

METHODS

We conducted a cross-sectional survey via a German web-based access panel in March 2022 that was stratified by age, gender, and education (N=1084). The participants are or have been diagnosed with cancer themselves (n=144) or have relatives who are or have been affected (n=990). All constructs were measured with established scales. To answer RQ1, descriptive data (mean values and distribution) were used. For RQ2, a blockwise multiple linear regression analysis was conducted.

RESULTS

Overall, 32.7% of participants were (rather) willing, 28.9% were undecided, and 38.4% were (rather) not willing to use a live chat on familial cancer risk in the future. A multiple linear regression analysis explained 47% of the variance. It revealed that performance expectancy, social influence, habit, perceived susceptibility, and perceived severity were positively associated with the intention to use a live chat on familial cancer risk. Effort expectancy, facilitating conditions, information insufficiency, and cancer diagnosis were not related to usage intentions.

CONCLUSIONS

A live chat seems promising for providing information on familial cancer risk. When promoting the service, the personal benefits should be addressed in particular. UTAUT2 is an effective theoretical framework for explaining live chat usage intentions and does not need to be extended in the context of familial cancer risk.

Understanding Trust Determinants in a Live Chat Service on Familial Cancer: Qualitative Triangulation Study With Focus Groups and Interviews in Germany

BACKGROUND

In dealing with familial cancer risk, seeking web-based health information can be a coping strategy for different stakeholder groups (ie, patients, relatives, and those suspecting an elevated familial cancer risk). In the vast digital landscape marked by a varied quality of web-based information and evolving technologies, trust emerges as a pivotal factor, guiding the process of health information seeking and interacting with digital health services. This trust formation in health information can be conceptualized as context dependent and multidimensional, involving 3 key dimensions: information seeker (trustor), information provider (trustee), and medium or platform (application). Owing to the rapid changes in the digital context, it is critical to understand how seekers form trust in new services, given the interplay among these different dimensions. An example of such a new service is a live chat operated by physicians for the general public with personalized cancer-related information and a focus on familial cancer risk.

OBJECTIVE

To gain a comprehensive picture of trust formation in a cancer-related live chat service, this study investigates the 3 dimensions of trust-trustor, trustee, and application-and their respective relevant characteristics based on a model of trust in web-based health information. In addition, the study aims to compare these characteristics across the 3 different stakeholder groups, with the goal to enhance the service's trustworthiness for each group.

METHODS

This qualitative study triangulated the different perspectives of medical cancer advisers, advisers from cancer support groups, and members of the public in interviews and focus group discussions to explore the 3 dimensions of trust-trustor, trustee, and application-and their determinants for a new live chat service for familial cancer risk to be implemented at the German Cancer Information Service.

RESULTS

The results indicate that experience with familial cancer risk is the key trustor characteristic to using, and trusting information provided by, the live chat service. The live chat might also be particularly valuable for people from minority groups who have unmet needs from physician-patient interactions. Participants highlighted trustee characteristics such as ability, benevolence, integrity, and humanness (ie, not a chatbot) as pivotal in a trustworthy cancer live chat service. Application-related characteristics, including the reputation of the institution, user-centric design, modern technology, and visual appeal, were also deemed essential. Despite the different backgrounds and sociodemographics of the 3 stakeholder groups, many overlaps were found among the 3 trust dimensions and their respective characteristics.

CONCLUSIONS

Trust in a live chat for cancer information is formed by different dimensions and characteristics of trust. This study underscores the importance of understanding trust formation in digital health services and suggests potential enhancements for effective, trustworthy interactions in live chat services (eg, by providing biographies of the human medical experts to differentiate them from artificial intelligence chatbots).

Do values and political attitudes affect help-seeking? Exploring reported help-seeking for mental health problems in a general population sample using a milieu framework

AIMS

Help-seeking for mental health problems is facilitated and hindered by several factors at the individual, interpersonal and community level. The most frequently researched factors contributing to differences in help-seeking behaviour are based on classical socio-demographic variables, such as age, gender and education, but explanations for the observed differences are often absent or remain vague. The present study complements traditional approaches in help-seeking research by introducing a milieu approach, focusing on values and political attitudes as a possible explanation for differences in help-seeking for emotional mental health problems.

METHODS

A representative cross-sectional survey of N = 3,042 respondents in Germany was conducted through face-to-face interviews about past help-seeking for mental health problems, socio-demographic characteristics and values and political attitudes.

RESULTS

Multivariate logistic regression analyses indicated that belonging to a cosmopolitan intellectual milieu group was significantly associated with an increased likelihood of past help-seeking for mental health issues (psychotherapeutic/psychological help-seeking [OR = 2.09, 95% CI: 1.11-3.93, p < 0.05) and primary care (OR = 2.21, 95% CI: 1.15-4.24, p < 0.05]), whereas members of individualist and conservative milieu groups were less likely to report having sought help from a psychotherapist, but not from a general practitioner. Increased odds ratios were also found for a number of socio-demographic variables, such as being aged 26 years and over, a female gender and more than 12 years of formal education. Associations between socio-demographic variables remained significant, and the explained variance of the used models improved considerably when milieu variables were added.

CONCLUSIONS

We discuss how milieu-specific patterns were relevant for explaining differences in mental health service use in addition to socio-demographic factors. It seems promising to consider help-seeking from a milieu perspective to improve disparities in access to and the use of psychotherapy as well as to resource allocation.

Exploring Functions and Predictors of Digital Health Engagement Among German Internet Users: Survey Study

BACKGROUND

Digital health engagement may serve many support functions, such as providing access to information; checking or evaluating one's state of health; and tracking, monitoring, or sharing health data. Many digital health engagement behaviors are associated with the potential to reduce inequalities in information and communication. However, initial studies suggest that health inequalities may persist in the digital realm.

OBJECTIVE

This study aimed to explore the functions of digital health engagement by describing how frequently respective services are used for a range of purposes and how these purposes can be categorized from the users' perspective. This study also aimed to identify the prerequisites for successfully implementing and using digital health services; therefore, we shed light on the predisposing, enabling, and need factors that may predict digital health engagement for different functions.

METHODS

Data were gathered via computer-assisted telephone interviews during the second wave of the German adaption of the Health Information National Trends Survey in 2020 (N=2602). The weighted data set allowed for nationally representative estimates. Our analysis focused on internet users (n=2001). Engagement with digital health services was measured by their reported use for 19 different purposes. Descriptive statistics showed the frequency with which digital health services were used for these purposes. Using a principal component analysis, we identified the underlying functions of these purposes. Using binary logistic regression models, we analyzed which predisposing factors (age and sex), enabling factors (socioeconomic status, health- and information-related self-efficacy, and perceived target efficacy), and need factors (general health status and chronic health condition) can predict the use of the distinguished functions.

RESULTS

Digital health engagement was most commonly linked to acquiring information and less frequently to more active or interactive purposes such as sharing health information with other patients or health professionals. Across all purposes, the principal component analysis identified 2 functions. Information-related empowerment comprised items on acquiring health information in various forms, critically assessing one's state of health, and preventing health problems. In total, 66.62% (1333/2001) of internet users engaged in this behavior. Health care-related organization and communication included items on patient-provider communication and organizing health care. It was applied by 52.67% (1054/2001) of internet users. Binary logistic regression models showed that the use of both functions was determined by predisposing factors (female and younger age) and certain enabling factors (higher socioeconomic status) and need factors (having a chronic condition).

CONCLUSIONS

Although a large share of German internet users engage with digital health services, predictors show that existing health-related disparities prevail in the digital realm. To make use of the potential of digital health services, fostering digital health literacy at different levels, especially in vulnerable groups, is key.

Oral cancer awareness campaign in Northern Germany: successful steps to raise awareness for early detection

PURPOSE

Oral cancer is an underestimated health problem, and its existence and the relevant prevention measures are not sufficiently known by the general population. The project thus aimed to develop, implement and evaluate an oral cancer campaign in Northern Germany, and to increase problem awareness on various levels: draw public attention to the tumour by media coverage increase awareness of early detection opportunities for the target group, and raise awareness of carrying out early detection measures by the professional groups involved.

METHODS

For each level, a campaign concept was developed and documented in terms of content and timing. The identified target group was elderly educationally disadvantaged male citizens ≥ 50 years. The evaluation concept for each level included pre-, post- and process evaluations.

RESULTS

The campaign was carried out from April 2012 to December 2014. The issue of awareness within the target group was significantly increased. Media coverage showed that regional media adopted the topic of oral cancer and placed it on their published agenda. Furthermore, the continuous involvement of the professional groups over the course of the campaign led to an increased awareness of oral cancer.

CONCLUSION

The development of the campaign concept with a comprehensive evaluation showed that the target group was successfully reached. The campaign was adapted to the required target group and specific conditions, and was also designed to be context sensitive. It is, therefore, recommended that the development and implementation of an oral cancer campaign on a national level be discussed.

Communication matters when it comes to adverse events: Associations of adverse events during implant treatment with patients' communication quality and trust assessments

OBJECTIVES

Because patients' trust in their physicians is a critical factor in improving health outcomes and patient response to adverse events, it is important to analyze the determinants of trust. One of these determinants is patient-centered communication. Because the occurrence of adverse events must be communicated to the patient, we asked whether the perceived quality of patient-physician communication acts as an isolating factor between adverse events and patient trust.

METHODS

We proposed and tested a structural equation model linking the occurrence of adverse events to the mediator patient-provider communication quality and to the outcome patient trust. The model was controlled for sociodemographic and health-related factors. We used online survey data from German implant patients (n = 1312), as implant treatment is associated with frequent adverse events such as infections.

RESULTS

Our results show that adverse events during implant treatment are associated with small but significantly lower trust levels. Patient-provider communication quality partially mediates this association.

CONCLUSIONS

Patient trust does not appear to be immune to deterioration from adverse events. Patient-provider communication plays a role in mitigating this association.

PRACTICE IMPLICATIONS

To improve the quality of care, attention should be paid to how adverse events are communicated in a patient-centered manner.

Understanding the Pathway of Cancer Information Seeking: Cancer Information Services as a Supplement to Information from Other Sources

Cancer information services (CISs) can play an important role within the pathway of cancer information seeking, but so far, this role is not well understood. Callers (n = 6,255) who contacted the largest provider of cancer information in Germany participated in a survey in which they reported their information sources, information level, and needs leading to the call. Persons with prior information from a physician (n = 1,507) were compared to people with prior online information (n = 901) and people with prior information from both sources (n = 2,776). Nearly all callers (96.7%) stated prior sources, while physicians and the Internet were the most frequently reported sources. People, who only talked to a doctor before, are more likely to be a patient and in the disease stages during/after the first treatment or with recurrence than prior Internet users. The two groups do not differ in their prior information level but did differ in their information needs. CISs are an important supplement to other sources, while the information repertoire depends on patients' stages during the cancer journey. Specific characteristics and needs of callers with different prior information sources help to individualize the service of CISs and similar providers.

Self- and surrogate-seeking of information about mental health and illness in Germany

BACKGROUND

Seeking information on mental health issues - both for oneself and on behalf of others (so-called surrogate-seeking) - is a critical early step in dealing with mental illness and known to impede stigmatizing attitudes and foster help-seeking. Yet, knowledge about mental health tends to be insufficient worldwide. Therefore, it is necessary to better understand the search for mental health information and examine the factors that are positively associated with information-seeking.

METHOD

In a face-to-face survey in Germany (N = 1,522), we investigated the factors related to mental health information-seeking. The data was analyzed by means of a logistic regression model, in which we distinguished those searching information for themselves from so-called surrogate seekers, i.e., people who seek information on behalf of someone else.

RESULTS

Twenty-six percent of German adults in our sample have already searched for information on mental health, with the majority already having searched for information for others (73% of all seekers). Our findings indicate that individuals' proximity to people with mental health issues, including their own mental health treatment experience (Cramer's V = .429, p < .001), education (Cramer's V = .184, p < .001), and desire for social distance from the affected people (F [1, 1516] = 73.580, p < .001, η² = .046), play an important role in mental health information-seeking. The patterns of sociodemographic and proximity factors hereby differ between self-seekers and surrogate-seekers.

CONCLUSIONS

Our study provides insights into the public's mental health information orientation. The findings may particularly guide strategies to improve mental health awareness and fill knowledge gaps in supporting informed decision-making and reducing stigma. Surrogate seekers appear to be an important and distinctive target group for mental health information provision. Depending on whether one wants to promote surrogate- or self-seeking seekers, different target groups and determinants should be addressed.

Changes in mental illness stigma over 30 years - Improvement, persistence, or deterioration?

BACKGROUND

Large efforts have been made to erase the stigma of mental illness, but it is unclear whether they have succeeded on a population level. We examine how attitudes toward people with depression or schizophrenia have evolved in Germany since 1990, and whether there are different developments for both disorders.

METHODS

Using data from the three decades, four wave repeated cross-sectional representative population study in the "old" (western) states in Germany with surveys in 1990 (n = 2,044), 2001 (n = 4,005), 2011 (n = 1,984), and 2020 (n = 2,449), we calculate time-trends for social distance and emotional reactions toward someone with major depression or acute schizophrenia.

RESULTS

Social distance worsened in six out of seven situations for schizophrenia, whereas improving in two out of seven situations for depression. Emotions related to fear and uneasiness increased for schizophrenia, whereas tending to decrease for depression. Pro-social reactions like the desire to help increased for depression, but decreased for schizophrenia. Initially observed differences, favoring depression over schizophrenia, widened over the 30-year study period. For schizophrenia, the biggest negative changes occurred between 1990 and 2001, whereas some improvements with regard to depression occurred more recently.

CONCLUSION

Contrary to expectations, stigma has become more severe regarding acute schizophrenia in Germany over the last 30 years, whereas only slightly improving for depression. The apparent normalization of mental health problems seems not to directly translate into improving attitudes toward people with severe mental illness. Re-focusing of anti-stigma efforts on people with severe mental illness seems necessary.

A Comparison of Women's and Men's Online Information Seeking Behaviors about Gender-Related Health Information: A German Stratified Online Survey (Preprint)

BACKGROUND

Gender-sensitive approaches to health communication aim to integrate gender perspectives at all levels of communication, as an individual's biological sex and socially assigned gender identity have an impact on whether and how one acquires what type of health information. Due to the fast and low-cost opportunity to search for a wide range of information, the internet seems to be a particularly suitable place for gender-related health information about diseases of sex-specific organs and diseases where biological differences are associated with different health risks.

OBJECTIVE

This study aims to inform gender-related information provision and acquisition in 2 ways. The first objective was to provide a theory-driven analysis of web-based health information-seeking behavior (HISB) regarding gender-related issues. Therefore, the Planned Risk Information Seeking Model (PRISM), which is one of the most integrative models of HISB, was adapted and applied. Second, we asked for gender-specific motivational determinants of gender-related web-based HISB comparing the predictors in the groups of women and men.

METHODS

Data from a stratified web-based survey of the German population (N=3000) explained gender-related web-based HISB and influencing patterns comparing women and men. The applicability of PRISM to gender-related web-based HISB was tested using structural equation modeling and a multigroup comparison.

RESULTS

The results revealed PRISM as an effective framework for explaining gender-related web-based HISB. The model accounted for 28.8% of the variance in gender-related web-based HISB. Gender-related subjective norms provided the most crucial explanatory power, followed by perceived seeking control. The multigroup comparison revealed differences in the model's explanatory power and the relevance of predictors of gender-related web-based HISB. The share of explained variances of web-based HISB is higher in men than in women. For men, norms were a more relevant promoting factor, whereas web-based HISB of women was more strongly associated with perceived seeking control.

CONCLUSIONS

The results are crucial for gender-sensitive targeting strategies and suggest gender-related health information interventions that address gender-related subjective norms. Furthermore, programs (eg, web-based learning units) should be developed and offered to improve individuals' (perceived) abilities to perform web-based searches for health information, as those with higher control beliefs are more likely to access web-based information.

Expanding the Health Information National Trends Survey Research Program Internationally to Examine Global Health Communication Trends: Comparing Health Information Seeking Behaviors in the U.S. and Germany

The Health Information National Trends Survey (HINTS) is a well-established U.S.-based research program administered by the National Cancer Institute to track the public access to and use of health information. This paper introduces a German research initiative, part of the International Studies to Investigate Global Health Information Trends (INSIGHTS) research consortium. This adaptation of the HINTS is important for initiating analyses of global health communication practices and comparing health information seeking behaviors (HISB) across nations to pinpoint potentials and challenges of health information provision and contribute to a deeper understanding of socio-contextual determinants of HISB. First cross-country comparisons revealed that the share of residents seeking for health information is high in the U.S. (80%) and Germany (74%), but different primary sources are used. Whereas a clear majority of U.S. residents chose the Internet to gather health information (74.9%), Germans most often turn to health professionals (48.0%). Socio-structural and health(care)-related predictors were found to contribute to the explanation of HISB in both countries, whereas information-related predictors were only relevant in Germany. The results indicate the need to engage in patient-provider communication to initiate HISB and to improve the access to information for residents with lower socio-economic backgrounds.

A Longitudinal Study of Physical and Mental Health and Health-Related Attitudes Among Music Students: Potentials and Challenges for University Health Promotion Programs

Objective

Well-being of music students has been an increasing matter of concern since studies show that up to 50% of beginners suffer from playing-related pain or anxiety. The aim of this longitudinal study was to examine health status, health-related attitudes, behaviors, knowledge, skills, and coping strategies of students at the beginning of their education at a music university and at the end of their second semester.

Methods

Based on a longitudinal online survey conducted among students at a German music university since 2017, we investigated mental and physical health status, health-related attitudes, knowledge, skills, behaviors, and coping strategies of music students at the beginning of their first year (n = 205). We analyzed differences between performance and music education majors and between students playing different main instruments. In a subsample (n = 62), we additionally analyzed changes between the beginning of the music students’ first and the end of their second semester, also depending on whether they attended courses on musicians’ health.

Results

Music students are already in demand when they enter a music university, practicing on average almost 3 h daily. Compared to other body regions, pain in shoulders/back is most prevalent in first-year students, especially in those playing string instruments. Performance majors reported better knowledge about health risks and protective measures for musicians, better coping abilities, and practiced more than music education majors. First-year students assessed their overall and mental health status at the beginning of their first semester mainly as good, but we found a decrease in mental health status at the end of the second semester. After two semesters, students attending courses on musicians’ health showed increased knowledge and skills regarding different aspects of musicians’ health.

Conclusion

The health status of music students when they first enter a music university is still a concern. Information and practical courses enabling students to prevent overuse and cope with performing anxiety and other stressors are important components of a comprehensive study program. Knowledge about music students’ needs can help conservatories better respond to the requirements and develop courses and measures supporting students from the beginning of their education.

OnkoRiskNET: a multicenter, interdisciplinary, telemedicine-based model to improve care for patients with a genetic tumor risk syndrome

Background

Genetic tumor risk syndromes are responsible for at least five to ten percent of the 4 million cases of cancer diagnosed in Europe every year. Currently, the care of oncological patients suffers from a lack of specialists in medical genetics and also a lack of access to genetic care in rural areas and structured care pathways between oncologists and medical geneticists. As a result, genetic tumor risk syndromes are underdiagnosed with potentially fatal consequences for patients and their families.

Methods

The OnkoRiskNET study is supported by a grant from the Federal Joint Committee of the Federal Republic of Germany. The study will include 2,000 oncological index patients from oncology practices in Lower Saxony and Saxony after the start of the study in July 2021. Randomization is carried out by means of a stepped wedge design at the level of the practices. Patients either go through routine care or the new form of care with structured cooperation between medical geneticists and oncologists, case management and the use of telemedical genetic counseling. Using a mixed-methods approach, the following parameters will be evaluated in the control and intervention group: (1) Conducted genetic counseling sessions by patients with suspected tumor risk syndrome and their first degree relatives; (2) Patient satisfaction and psychological distress after genetic counseling and testing; (3) Factors influencing the acceptance and experience of telemedical genetic counseling; (4) Satisfaction of oncologists and medical genetics with the structured pathway; (5) Cost efficiency of the new form of care.

Discussion

OnkoRiskNET aims to close the gap in care through the formation of a cooperation network between practicing oncologists and specialists in medical genetics and the use of telemedical genetic counseling, thereby, increasing the diagnostic rate in genetic tumor risk syndromes and serving as a model for future genetic care in Germany.

Explaining Online Information Seeking Behaviors in People With Different Health Statuses: German Representative Cross-sectional Survey

Background

Worldwide, the internet is an increasingly important channel for health information. Many theories have been applied in research on online health information seeking behaviors (HISBs), with each model integrating a different set of predictors; thus, a common understanding of the predictors of (online) HISB is still missing. Another shortcoming of the theories explaining (online) HISB is that most existing models, so far, focus on very specific health contexts such as cancer. Therefore, the assumptions of the Planned Risk Information Seeking Model (PRISM) as the latest integrative model are applied to study online HISB, because this model identifies the general cognitive and sociopsychological factors that explain health information seeking intention. We shift away from single diseases and explore cross-thematic patterns of online HISB intention and compare predictors concerning different health statuses as it can be assumed that groups of people perceiving themselves as ill or healthy will differ concerning their drivers of online HISB. Considering the specifics of online HISB and variation in individual context factors is key for the development of generalizable theories.

Objective

The objective of our study was to contribute to the development of the concept of online HISB in 2 areas. First, this study aimed to explore individual-level predictors of individuals’ online HISB intention by applying the postulates of PRISM. Second, we compared relevant predictors of online HISB in groups of people with different health statuses to identify cross-thematic central patterns of online HISB.

Methods

Data from a representative sample of German internet users (n=822) served to explain online HISB intentions and influencing patterns in different groups of people. The applicability of the PRISM to online HISB intention was tested by structural equation modeling and multigroup comparison.

Results

Our results revealed PRISM to be an effective framework for explaining online HISB intention. For online HISB, attitudes toward seeking health information online provided the most important explanatory power followed by risk perceptions and affective risk responses. The multigroup comparison revealed differences both regarding the explanatory power of the model and the relevance of predictors of online HISB. The online HISB intention could be better explained for people facing a health threat, suggesting that the predictors adopted from PRISM were more suitable to explain a problem-driven type of information-seeking behavior.

Conclusions

Our findings indicate that attitudes toward seeking health information online and risk perceptions are of central importance for online HISB across different health-conditional contexts. Predictors such as self-efficacy and perceived knowledge insufficiency play a context-dependent role—they are more influential when individuals are facing health threats and the search for health information is of higher personal relevance and urgency. These findings can be understood as the first step to develop a generalized theory of online HISB.

Efficacy Assessments as Predictors of Uncertainty Preferences

Abstract. Background: Health challenges can cause feelings of uncertainty that individuals intend to reduce, increase, or maintain. Those goals are connected to different information seeking and avoidance behaviors, building four uncertainty preferences. Aims: We aim to understand what drives people to seek or avoid information through a more differentiated look at the underlying uncertainty preferences and their determinants. Our starting point to explain different uncertainty preferences are stable, individual traits determining individuals’ efficacy assessments. Method: We conducted a secondary analysis of an online survey among the German public in a sample with stratified demographic characteristics ( N = 3,000). The questionnaire measured different uncertainty preferences as well as coping efficacies and communication efficacy. Regression analyses determined the relevance of these predictors for the four uncertainty preferences. Results: The considered efficacy assessments explained a greater amount of variance in uncertainty preferences applying information seeking than information avoidance, but the influencing patterns are similar. Only health literacy as a communication efficacy was positively associated with both preferences applying information seeking and negatively associated with both preferences applying information avoidance. Limitations: The concept of uncertainty preferences should be critically assessed concerning its completeness. The low explanatory power of efficacy assessments for preferences underlying information avoidance strategies shows that further research is needed to identify relevant predictors. Conclusion: The findings suggest that efficacy assessments provide cognitive resources for goal-oriented uncertainty management, but a deeper understanding of specific underlying mechanisms of the different preferences requires further examination.

Explaining cancer information avoidance comparing people with and without cancer experience in the family

OBJECTIVES

Cancer information avoidance (CIA) serves as a barrier to preventive efforts. To learn how to combat this barrier, we aim to examine predictors of CIA in populations with and without cancer experience in the family, which are addressed differently in cancer prevention, according to specific informational barriers.

METHODS

A subsample of people with and without cancer in the family (n = 2,757) of an online survey with a sample stratified for the German population by age, gender, education, and region was conducted via an online access panel. The survey instrument was adapted from the Health Information National Trends Survey. Separate stepwise regression analyses were conducted.

RESULTS

Only a comparatively small proportion of the variance in CIA was explained by the predictors, ranging from R²  = .148 for people without cancer experience to R²  = .180 for participants with cancer experience in their family. Across the groups, the findings showed that people who were fatalistic about the risk of cancer, less health literate, who perceived less social pressure to be informed, and were less trusting in information sources more often avoided cancer information.

CONCLUSIONS

Our findings identify relevant target groups to be addressed and barriers to be removed for cancer communication efforts. Adequate information provision can be supported by programs for fostering health literacy and social network diffusion strategies.

Correlates of the perceived quality of patient-provider communication among German adults

BACKGROUND

Since a higher perceived quality of patient-provider communication is known to be associated with improved health outcomes, it is essential to analyze determinants influencing patients' perceived quality of patient-provider communication. Due to the limited knowledge about patient-related influencing factors of quality perception available so far, the objective of this study is to explore and assess determinants of the perceived quality of patient-provider communication with regards to sociodemographic, health-related, healthcare-specific and information-related factors.

METHODS

Linear regression of cross-sectional data from the first wave of Health Information National Trends Survey Germany (n = 2902) was conducted. Independent variables were sociodemographic, health-, healthcare- and information-related factors; the dependent variable was the perceived quality of patient-provider communication.

RESULTS

Results show that age, migration background, the perceived quality of healthcare, health-related self-efficacy and trust in health information from health professionals are significantly associated with the perceived quality of patient-provider communication.

CONCLUSIONS

Sociodemographic, healthcare- and health information-related factors influence the perceived quality of patient-provider communication. In particular, patients having a migration background and patients reporting low self-efficacy showed significant lower levels of their perceived patient-provider communication quality. With the aim to improve quality issues, patients of both target groups should be empowered and supported.

[Cyberchondria - A New Behavioral Syndrome?]

Investigation of cyberchondria is still in its infancy. Preliminary research suggests that cyberchondria is likely to represent a distinct behavioral syndrome which is closely associated with health anxiety/hypochondria and extensive online searching for health information and/or digital self-tracking. The internet is characterized by anonymous, readily, convenient space-time-independent accessibility and availability of an almost unmanageable amount of information that may increase the reassurance-seeking safety behavior of individuals with heightened health anxiety. Cyberchondria also appears to be related to low self-esteem, anxiety sensitivity, intolerance of uncertainty, compulsivity and metacognitive beliefs. At present, it is unclear of whether individuals with cyberchondria suffer from extensive health-related online searching behavior only or also from other forms of internet use disorders. The link between cyberchondria and e-health literacy, defined as perceived skills at finding, evaluating, and applying online health information to health problems, is poorly recognized. At present, there are no standardized therapeutic interventions for cyberchondria available. Treatment should address the maladaptive health- or illness-related assumptions and beliefs by using existing, well established approaches for hypochondria. Furthermore, it should target the problematic internet use and enable individuals with cyberchondria to reflect their subjective e-health literacy and promote a functional use of health resources from the internet.

Studying Music During the Coronavirus Pandemic: Conditions of Studying and Health-Related Challenges

Objective

The coronavirus pandemic affects all areas of life. Performing arts and music studies have also experienced considerable changes, with university closures and a fluctuating return to normal and more limited operations. Prior studies detail the impact of the pandemic on college students, but we do not yet know what specific consequences it has for music students. The aim of this study is to examine the impact of the coronavirus pandemic on music students' health, practicing behavior, and everyday life.

Methods

In July 2020, we conducted an online survey of 80 students enrolled in performance and music education programs at a German music university and compared these data with data from a survey of 75 students at the same music university carried out in summer 2019.

Results

The survey revealed that the coronavirus pandemic led to a decrease in practicing hours and an increase of stressful thoughts and feelings. Students were mostly satisfied with Corona-measures taken by the university. Of analyzed determinants, only general fear of health problems was identified as a significant predictor of mental health status. Mental health status did not significantly differ between students surveyed in 2019 and 2020.

Conclusion

Knowledge about the specific challenges the pandemic poses for music students can help conservatories to better respond to the needs of their students. Specifically, this study will inform future measures supporting music students in coping with difficult situations like a pandemic.

Nature of fiber-coupled detector responsivity measurements at 0.1% using a primary standard

We demonstrate the capability to measure the absolute power responsivity of optical fiber-coupled detectors at an expanded uncertainty of 0.1%, by direct comparison with a cryogenic primary standard. To facilitate synchronous power measurements, commercial all-fiber beam-splitters direct laser diode light simultaneously to the device under test and the primary standard. We investigate the use of single-mode, polarisation maintaining, and photonic crystal fibers to access the cryogenic standard, and report a reduction in the temperature dependent effective refractive index of these fibers of 0.1%, 0.15% and 0.3% respectively in going from room temperature to 5 K. We also evaluate the polarisation dependent loss of the beam-splitters, the stability of the beam-splitter ratio between the cryogenic detector and the device under test and the temporal and modal stability of the Fabry-Pérot laser diode sources. It is shown that the stability of the optical fiber beam-splitters limits the overall performance of the measurement system to an expanded uncertainty of 0.1%.

Exploratory Research Focusing on Oral Cancer Prevention: Challenges of Dealing With Informational and Cognitive Barriers

Oral cancer is a considerable public health problem, and a low level of awareness and knowledge about this tumor and its risk factors is prevalent. To gain a profound understanding of risks groups and to identify suitable communication strategies for a prevention campaign in Northern Germany, an exploratory research was realized. In semistructured face-to-face interviews, the participants of the study (n = 28) described their individual oral cancer-related perceptions and information-seeking behaviors. A computer-assisted qualitative data analysis showed a vague but also deterring picture of cancer combined with restricted attitudes toward the topic and an inactive or even avoiding information behavior. Four underlying cognitive patterns of self-distancing were identified: (a) optimistic bias, (b) fatalism, (c) hedonism, and (d) pragmatism. The main challenge of oral cancer prevention is to deal with the target groups' informational and cognitive barriers.

A conceptual framework for an oral cancer awareness campaign in Northern Germany - Challenges in campaign development and assessment

Initial impetus for action: Oral cancer is still an underestimated disease in terms of incidence as well as mortality rates; it requires urgent prevention and early detection. At present, there is no best-practice systematic approach to raising awareness and informing the public about about this type of cancer in Germany. This article describes a framework that covers the significant stages of conceptual development and campaign design to promote oral cancer awareness in Germany. Solution: The challenges of the development, as well as evaluation of an oral cancer awareness campaign are shared in this article. Four key stages of the campaign are defined: (1) mass media, (2) target groups, (3) health care professionals, and (4) epidemiology. For each section, the following levels of assessment are proposed: (a) campaign development (formative assessment), (b) controlling and optimising campaign implementation (process assessment) and (c) measuring outcomes (summative assessment). Outcome: A process-oriented assessment concept for each of the four campaign sections was developed and merged to form a matrix, which includes each of the above sections regarding the prevention and early detection of oral cancer, as well as the three stages of campaign assessment. Future implications and learning points: The conceptual framework demonstrated that systematic planning and evaluation of different components helped to describe and evaluate an oral cancer campaign: For future campaigns, the use of a matrix covering different campaign targets as well as the entire campaign process, is recommended as a basis for campaign design and evaluation.

[Trends in cancer information services over 25 years : An analysis of inquiries from patients and relatives made to the Cancer Information Service of the German Cancer Research Center from 1992 to 2016]

BACKGROUND

Cancer information services (CISs) are a valuable source of evidence-based information. Previous studies in the field of CISs often investigate only short periods of time. However, there is a need for long-term analyses to identify changes in the use of CISs.

OBJECTIVES

The purpose of this study was to analyze trends in the inquiries of patients and surrogate seekers to a CIS.

METHOD

We conducted a secondary data analysis of the inquiry records of the German CIS (Krebsinformationsdienst, KID) hosted by the German Cancer Research Center from 1992 until 2016 (N = 545,070). Trends in the number of inquiries were described using the whole sample, while the description of further characteristics is based on a sample (n = 55,046) of patients, their family members, and friends.

RESULTS

The inquiries increased in the period examined (1992: 11,344 inquiries; 2016: 34,869 inquiries). Since 2005, a greater share of patients (between 52 and 60%) than surrogate seekers have been contacting the CIS. The mean age of both self-seeking and supported patients increased from under 55 years between 1992 and 2000 up to over 60 years in the year 2016. Breast cancer is at all times the most frequently inquired cancer type (patients: n = 11,319, 39%; surrogate seekers: n = 4173, 17%). Even after the implementation of e‑mail as an additional communication channel, the majority of inquirers still prefer contact by phone (between 80 and 98%).

CONCLUSIONS

Changes in the utilization of a CIS over time are discussed against the background of structural changes, such as shifts in prevalence rates, family structures, or media environments.

Demographic and cancer-related differences between self-seeking patients and supported patients: Analysis of cancer information-service data

OBJECTIVE

Surrogate information seeking is quite common, and several studies have presented data on caregivers, family members, and friends who seek health information on the Internet or from a cancer-information service (CIS) on behalf of cancer patients. However, these studies provide little information about the patients who are supported by surrogate seekers. Therefore, this study analyzed demographic and cancer-related differences, including diverse informational needs, between self-seeking patients and patients who benefited from surrogate seekers (ie, caregivers, family, or friends) requesting information on their behalf.

METHODS

We conducted a retrospective audit of phone and e-mail inquiries to a German CIS between January and December 2016 from self-seeking patients (n = 13 723) and surrogate information seekers, as well as the corresponding supported patients (n = 6696).

RESULTS

Supported patients were more likely to be males (P < 0.001), older than self-seeking patients (P < 0.001), and older than the corresponding surrogate seekers (P < 0.001). They were also more likely to be in the diagnostic or palliative stage (P < 0.001) and were less likely to suffer from breast cancer or prostate cancer (P < 0.001) than self-seeking patients. There were significant differences in the CIS requests of self-seekers and surrogate seekers.

CONCLUSIONS

The results point to different support needs of self-seekers and surrogate seekers. Thus, surrogate seekers and their corresponding supported patients should be seen as a separate target group to self-seeking patients, with the former requiring informational and emotional support on diverging topics and at different disease stages.

The Role of Sulfur Dioxide in Stratospheric Aerosol Formation Evaluated Using In-Situ Measurements in the Tropical Lower Stratosphere

Stratospheric aerosols (SAs) are a variable component of the Earth's albedo that may be intentionally enhanced in the future to offset greenhouse gases (geoengineering). The role of tropospheric-sourced sulfur dioxide (SO₂) in maintaining background SAs has been debated for decades without in-situ measurements of SO₂ at the tropical tropopause to inform this issue. Here we clarify the role of SO₂ in maintaining SAs by using new in-situ SO₂ measurements to evaluate climate models and satellite retrievals. We then use the observed tropical tropopause SO₂ mixing ratios to estimate the global flux of SO₂ across the tropical tropopause. These analyses show that the tropopause background SO₂ is about 5 times smaller than reported by the average satellite observations that have been used recently to test atmospheric models. This shifts the view of SO₂ as a dominant source of SAs to a near-negligible one, possibly revealing a significant gap in the SA budget.

Surrogate health information seeking in Europe: Influence of source type and social network variables

OBJECTIVES

Health information seeking on behalf of others is an important form of social support by which laypeople provide important sources of information for patients. Based on social network theory, we analyze whether this phenomenon also occurs in offline sources. We also seek to learn more about the type of relationships between information seekers and patients, as research to date indicates that surrogate seeking mostly occurs in close relationships between the seeker and the patient.

METHODS

Using a large-scale representative survey from the 28 member states of the European Union (N=26,566), our data comprise all respondents who reported seeking health information online or offline (n=18,750; 70.6%).

RESULTS

Within the past year, 61.0% of the online health information seekers and 61.1% of the offline health information seekers had searched on behalf of someone else. Independent of the information channel, surrogate seekers primarily searched for health information for family members (online: 89.8%; offline: 92.8%); they were significantly less likely to search for information on behalf of someone with whom they had weaker ties, such as colleagues (online: 25.1%; offline: 24.4%). In a multilevel generalized linear model, living together with someone was by far the most relevant determinant for surrogate seeking, with differences between countries or Internet activity being less important.

CONCLUSION

These results support the assumptions of social network theory. Implications are discussed, especially with regard to the provision of adequate health information.

Gender-Specific Determinants and Patterns of Online Health Information Seeking: Results From a Representative German Health Survey

Background

Online health information-seeking behavior (OHISB) is currently a widespread and common behavior that has been described as an important prerequisite of empowerment and health literacy. Although demographic factors such as socioeconomic status (SES), age, and gender have been identified as important determinants of OHISB, research is limited regarding the gender-specific motivational determinants of OHISB and differences between women and men in the use of online resources for health information purposes.

Objective

The aim of this study was to identify gender-specific determinants and patterns of OHISB by analyzing data from a representative German sample of adults (N=1728) with special attention to access and frequency of use as well as topics and sources of OHISB.

Methods

We employed a 2-step analysis, that is, after exploring differences between users and nonusers of online health information using logistic regression models, we highlighted gender-specific determinants of the frequency of OHISB by applying zero-truncated negative binomial models.

Results

Age (odds ratio, OR for females=0.97, 95% CI 0.96-0.99) and degree of satisfaction with one’s general practitioner (GP) (OR for males=0.73, 95% CI 0.57-0.92) were gender-specific determinants of access to OHISB. Regarding the frequency of OHISB, daily Internet use (incidence rate ratio, IRR=1.67, 95% CI 1.19-2.33) and a strong interest in health topics (IRR=1.45, 95% CI 1.19-1.77) were revealed to be more important predictors than SES (IRR for high SES=1.25, 95% CI 0.91-1.73).

Conclusions

Users indicate that the Internet seems to be capable of providing a valuable source of informational support and patient empowerment. Increasing the potential value of the Internet as a source for health literacy and patient empowerment requires need-oriented and gender-specific health communication efforts, media, and information strategies.

Tailoring in risk communication by linking risk profiles and communication preferences: The case of speeding of young car drivers

Speeding is one of the most relevant risk behaviors for serious and fatal accidents, particularly among young drivers. This study presents a tailoring strategy for anti-speeding communication. By referring to their motivational dispositions toward speeding derived from motivational models of health behavior, young car drivers were segmented into different risk groups. In order to ensure that risk communication efforts would actually be capable to target these groups, the linkage between the risk profiles and communication preferences were explored. The study was conducted on the basis of survey data of 1168 German car drivers aged between 17 and 24 years. The data reveal four types of risk drivers significantly differing in their motivational profiles. Moreover, the findings show significant differences in communication habits and media use between these risk groups. By linking the risk profiles and communication preferences, implications for tailoring strategies of road safety communication campaigns are derived. Promising segmentation and targeting strategies are discussed also beyond the current case of anti-speeding campaigns.

Challenges of early detection of oral cancer: raising awareness as a first step to successful campaigning

In Germany, ∼ 13,000 people are found to have oral and pharyngeal cancer every year. Awareness and knowledge about this cancer remain insufficient, particularly amongst elderly people. A campaign for early detection was launched in Northern Germany in April 2012. The first step of the campaign was to increase awareness about oral cancer. Prior to a pre-campaign evaluation at the campaign start, March 2012 and an intermediate-campaign evaluation, November 2012, a sample representative for the population aged 50 ≥ years (target group; N = 500) was drawn for a first process evaluation. The surveys were conducted by means of telephone interviews including questions on behaviour, knowledge and sociodemographic/socioeconomic aspects and target group-oriented questions on issue, media and campaign material awareness. The process evaluation showed an increase in issue awareness from 25 to 40% (P < 0.001) and the media awareness increased by over 10% (P < 0.001). The results suggested that particularly women, the core age group (60-79 years) and the educationally disadvantaged group might benefit from the campaign. Awareness about the issue 'oral cancer' was already significantly increased 7 months after the campaign start. The highest general and media-related increase in awareness was achieved in the target group.

Invited Article: A compact optically coherent fiber frequency comb

We describe the design, fabrication, and performance of a self-referenced, optically coherent frequency comb. The system robustness is derived from a combination of an optics package based on polarization-maintaining fiber, saturable absorbers for mode-locking, high signal-to-noise ratio (SNR) detection of the control signals, and digital feedback control for frequency stabilization. The output is phase-coherent over a 1-2 μm octave-spanning spectrum with a pulse repetition rate of ∼200 MHz and a residual pulse-to-pulse timing jitter <3 fs well within the requirements of most frequency-comb applications. Digital control enables phase coherent operation for over 90 h, critical for phase-sensitive applications such as timekeeping. We show that this phase-slip free operation follows the fundamental limit set by the SNR of the control signals. Performance metrics from three nearly identical combs are presented. This laptop-sized comb should enable a wide-range of applications beyond the laboratory.

Comb-calibrated laser ranging for three-dimensional surface profiling with micrometer-level precision at a distance

Non-contact surface mapping at a distance is interesting in diverse applications including industrial metrology, manufacturing, forensics, and artifact documentation and preservation. Frequency modulated continuous wave (FMCW) laser detection and ranging (LADAR) is a promising approach since it offers shot-noise limited precision/accuracy, high resolution and high sensitivity. We demonstrate a scanning imaging system based on a frequency-comb calibrated FMCW LADAR and real-time digital signal processing. This system can obtain three-dimensional images of a diffusely scattering surface at stand-off distances up to 10.5 m with sub-micrometer accuracy and with a precision below 10 µm, limited by fundamental speckle noise. Because of its shot-noise limited sensitivity, this comb-calibrated FMCW LADAR has a large dynamic range, which enables precise mapping of scenes with vastly differing reflectivities such as metal, dirt or vegetation. The current system is implemented with fiber-optic components, but the basic system architecture is compatible with future optically integrated, on-chip systems.

Development of a dynamic model for ventral hernia mesh repair

Introduction

The adequate way of mesh fixation in laparoscopic ventral hernia repair is still subject to debate. So far, simulation has only been carried out in a static way, thereby omitting dynamic effects of coughing or vomiting. We developed a dynamic model of the anterior abdominal wall.

Materials and methods

An aluminium cylinder was equipped with a pressure controlled, fluid-filled plastic bag, simulating the abdominal viscera. A computer-controlled system allowed the control of influx and efflux, thus creating pressure peaks of up to 200 mmHg to simulate coughing and 290 mmHg to simulate vomiting. We tested fixation with tacks (Absorbatack, Covidien Deutschland, Neustadt a. D., Germany). The model was controlled for the friction coefficient of the tissue against the mesh and the physiologic elasticity of the abdominal wall surrogate.

Results

The model was able to create pressure peaks equivalent to physiologic coughs or vomiting. Physiologic elasticity was thereby maintained. We could show that the friction coefficient is crucial to achieve a physiologic situation.

The meshes showed a tendency to dislocate with an increasing number of coughs (Fig. 4). Nevertheless, when applied in a plain manner, the meshes withstood more cough cycles than when applied with a bulge as in laparoscopic surgery.

Conclusions

The dynamic movement of the abdominal wall, the friction between tissue and mesh and the way of mesh application are crucial factors that have to be controlled for in simulation of ventral abdominal hernia closure. We could demonstrate that patient specific factors such as the frequency of coughing as well as the application technique influence the long term stability of the mesh.
