Publication Cultural differences in social media use, privacy, and self-disclosure : research report on a multicultural study(2016) Masur, Philipp K.; Trepte, SabineThis research report presents comparative results from five nations (United States of America, United Kingdom, Germany, the Netherlands, and China) with regard to social media use, self-disclosure, privacy perceptions and attitudes, and privacy behavior in online environments. The data stemmed from an online survey that was conducted from November, 2011, to December, 2011. Across all five nations, N = 1,800 participants completed the survey. The findings suggest that a broad differentiation between Western and Eastern cultures only partly accounted for differences in social media use and privacy behavior. Rather, the results of this report suggest that European countries (United Kingdom, Germany, and the Netherlands) share similar privacy perceptions and show similar behavioral patterns. Non-European cultures (the USA and China) on the other hand, use social media differently. Participants from European countries had generally smaller audiences on social network sites and microblogging platforms, tended to limit the visibility of their postings and profile information more, and used more privacy settings to safeguard their privacy. In particular, German social media users seemed to be guarded, protective, and rather reluctant to participate in online communication. Users from the US, on the other hand, rated privacy-related behavior as less risky and were hence less likely to imply sophisticated privacy strategies. Apart from these findings, the report also shows that there are more commonalities than differences. People from all five countries think that it is important to protect privacy. Most users consciously decides what to share and what not to share. Accordingly, social media users do not always share intimate and detailed information about their lives.Publication A gendered perspective on online privacy and self-disclosure(2024) Frener, Regine; Trepte, SabineIn research on online privacy and self-disclosure, gender is commonly included as a potentially predictive variable. The results are heterogeneous and sometimes controversial; explanations are often lacking or based on stereotypical assumptions. With this dissertation, I seek to provide a gender-focused perspective on online privacy and self-disclosure by taking a closer look at gender effects in privacy-related outcomes, studying the implementation of gender as a research variable, and investigating how gender is related to people’s inherent need for privacy. To this end, I present a short introduction in the first chapter, followed by four publications: a book chapter on privacy and gender (Study 1), a systematic literature review (Study 2), an empirical investigation of gender effects in privacy behavior (Study 3), and the development of the Need for Privacy Scale (NFP-S; Study 4). In Study 1, the book chapter, I summarize key theoretical advancements in gender and privacy research in line with the feminist movement. Further, empirical findings on gender disparities are presented from a communication science perspective. I discuss the ongoing gender-based digital divide as well as risks associated with automatic gender categorization. Lastly, I address the problems of conceptualizing gender as a binary, static variable, and propose alternative perspectives for more equitable treatment. In Study 2, my co-author Prof. Dr. Sabine Trepte and I examine how scholars in the field of online privacy incorporate gender into their research. For n = 107 articles reporting gender effects (or a lack thereof), we assess whether gender theory is included, to what extent it is referred to, and what function it serves. The results show that in most studies, gender is undertheorized, resulting in reduced explanatory power and the risk of gender essentialism. To meet the need for gender theorization in online privacy research we identified in Study 2, I present an empirical investigation of the social web gendered privacy model (Thelwall, 2011) in Study 3. The model aims to link gender differences in online privacy concerns, data protection behavior and online self-disclosure and explain them via gender differences in offline factors. Using longitudinal data (n = 1,043), I found partial support for the relationships between the privacy-related variables as well as for the transfer from offline to online contexts. The expected gender differences did not arise consistently, which challenges the model’s claim that women constitute an especially vulnerable population regarding social media usage. To offer added value for the broader field of privacy-related research, my co-authors Jana Dombrowski and Prof. Dr. Sabine Trepte and I present the Need for Privacy Scale (NFP-S) in Study 4. The NFP-S is a concise measure of the need for privacy as a personality trait, developed to be applied in any context. Against the theoretical backdrop of Burgoon’s (1982) privacy dimensions, we propose a second-order model with informational, psychological, and physical need for privacy as the first-order factors. In two large-scale surveys (Study 1: n1 = 3,278; n2 = 1,226; Study 2: N = 1,000), the scale was validated with regard to relevant personality traits, privacy-related cognitive criteria and behaviors as well as socio-demographic variables. With the goal of disentangling (biological) sex and gender, we include self-assessed femininity and masculinity. We find that congruity between participants’ perception of their femininity/masculinity and their sex is related to a higher need for privacy. In the overall discussion, I combine insights from the studies, provide ideas for future research, and offer societal and practical implications. Taken together, the four studies contribute to the field of online privacy by emphasizing the psychological perspective of gender as a socially constructed, multifaceted, and dynamic construct. Adopting this view is desirable for privacy researchers, as it helps to better understand privacy-related attitudes and decision-making, hence increasing overall validity. Furthermore, a differentiated understanding of gender is needed to prevent oversimplifications and stereotyping and to promote ethical and fair research.Publication Issues Management unter veränderten Umweltbedingungen(2023) Wnuck, Corinna; Schweiger, WolfgangThe idea of issues management aims to ensure that companies actively exert influence on other environmental developments through early identification and strategically planned participation in publicly and organisationally relevant issues. The goal is to maintain their own room for manoeuvre and secure their corporate reputation. Environmental conditions play a central role in shaping issues management. These have changed noticeably since the first issues manage- ment approaches at the end of the 1970s. Digitalisation, medialisation, globalization, and the transformation of the public sphere through digital structural change are the drivers of these changes. Issues management has not yet been tested for its validity under changed environmen- tal conditions. The overarching research question of this study therefore is: How do companies shape issues management under changed environmental conditions? The empirical study uses qualitative, guideline-based expert interviews to examine how issues management is carried out today under changed environmental conditions. For this purpose, the research question is deepened on the basis of six issue management dimensions: the concept, the structure, the process, the management, the actor and the resource dimension. For the research, 22 experts from the agency/consultancy context and the corporate environment were interviewed. Conceptually, issues management has not altered under changed environmental conditions. It remains a preventive function that identifies issues in the corporate environment as early as possible in order to secure and enhance the companys reputation and to deal with these issues in a strategically planned manner. Issues management has a deprioritised existence in many companies, partly because the overlaps with other disciplines are high. Therefore, in many com- panies issues management is practised but not called such. At the structural level of issues management, changes due to digitalisation and globalisation are becoming visible. Modern is- sues management organisations have to work faster, more agile and more flexibly than before. They have to identify issues globally, in real time, and prepare them in a way that is appropriate for different cultural areas. This requires efficient and transparent information and knowledge management systems as well as flexible resource adjustment options. The study shows that changes due to digitalised environmental conditions are effective on the processual level. Due to the acceleration of environmental developments, the process phases run faster or parallel to each other. Reflection and reaction times have shortened with increasing issue complexity. Fol- lowing the sequences of the Scrum logic from software development, an alternative process model is developed in the study that maps the simultaneity and growing complexity of environ- mental developments. The management level is characterised by changes due to accelerated environmental developments, globalisation, medialisation and changed public structures, which are evident to different degrees in the individual phases of the management level. The study shows that the evaluation of issues management is still a challenge today and is only carried out with limitations in the companies. Agencies see a lack of will here, companies justify this with the lack of meaningfulness of the results about the actual performance of issues management. At the actor level, the transformation of the public sphere is having an effect. There is an in- crease in the number of situational, volatile and well-networked sub-publics, which are grouped around various issues and ensure that once an issue has arisen, it can no longer be laid to rest. In addition, the balance of power has shifted in favour of previously weakly represented groups. Furthermore, "journalism bypassing" is a frequently observed phenomenon. On the resource level, issues managers need a significantly expanded repertoire of competences and skills due to digitalisation and medialisation. Furthermore, the use of digital tools in issues management is increasing. At the time of the survey, these were primarily online monitoring tools, editorial management tools, collaborative work platforms and virtual team environments. AI and chat- bots, on the other hand, are the exception. Overall, the study concludes that the changed environmental conditions make the idea of issues management more relevant than ever. Although not always under the name, strategically planned early recognition and management of issues has become established in most compa- nies. At the same time, the environmental changes have a strong impact on implementation. Furthermore, there is a need to catch up especially in the area of digital and data-based corporate communication. This is where potential lies dormant to remedy some of the problems identified in the paper.Publication Navigating the information landscape: uncovering links between information perception, processing, and behavior(2023) Utz, Lena; Gimpel, HennerDigitalization has transformed how individuals access and share information, making some of it available anytime and anywhere through the internet, mobile devices, and social media. Digitalization has also changed how information is created and disseminated, enabling individuals to actively participate in the Information Age by creating user-generated content. The exponential growth of digital content presents both opportunities and challenges. While individuals can access information quickly and easily regarding a wide range of topics, it is essential to distinguish between truthful and false information. Fake news, especially from social media, has political and societal consequences, eroding trust in traditional media and institutions. Additionally, even if the information is true, individuals can be intentionally or unintentionally manipulated by specific characteristics of the information. Cognitive biases, such as the negativity effect and confirmation bias, influence how people perceive and process information. Individuals’ social environments, platform design, and individual characteristics also shape how they deal with information. To navigate the information landscape, it is essential to understand how individuals perceive and process information and how it can influence their behavior. This topic is a subject of the study of Human Information Behavior. To better understand the links, this dissertation builds on the Stimulus-Organism-Response model. This psychological model explains how stimuli (such as information) influence an individual’s cognitive and emotional state (organism), leading to observable behaviors (responses). Thereby, the dissertation distinguishes between primary and context stimuli, between cognitive and affective processes as part of the organism, and between psychological and behavioral responses. This cumulative dissertation aims to contribute to the understanding of how individuals perceive and process information and how information influences their behavior. For this purpose, it relies on literature-based theorizing and the analysis and interpretation of empirical data obtained from online experiments and surveys. Because false information tremendously influences society, politics, and every individual, this dissertation focuses on fake news. The first three chapters examine socio-technical interventions to combat fake news. Chapter 2 provides an approach to improving reporting behavior. It analyzes the influence of injunctive and descriptive social norms (SNs) on social media users’ reporting of fake news. The findings revealed that SN messages influence users’ re-porting behavior. While injunctive SN messages can serve as motivational tools and affect user reporting behavior in social media environments, the empirical results demonstrated no significant effect from the sole application of descriptive SN messages. However, combining both types of SN messages proved to be the most effective approach. Chapter 3 addresses the influence of the order of intervention on the short- and long-term perception of fake news. The findings showed that the order in which the intervention, consisting of warning messages and verified information, is displayed impacts the perception of fake news. When delivered after fake news exposure, such interventions can decrease the believability of fake news more effectively than interventions delivered before exposure. Chapter 4 examines how the fake news reader’s emotions influence the believability of fake news and whether warning labels can mitigate these effects. The results revealed that while low-arousal emotions in the reader could decrease the believability of fake news, high-arousal emotions did not affect believability compared to the control group. However, the presence of a warning label before reading the fake news could reduce its believability, regardless of the level of emotional arousal. Chapter 5 broadens the perspective beyond fake news. Using the example of online product reviews and information, it examines how different characteristics of information influence the user evaluation of digital products. The findings revealed that there is a “placebo effect.” This placebo effect depends on the source of information and negative placebo information has a stronger effect than positive placebo information. Furthermore, the timing of the presentation of the placebo information is important. Placebo information provided after physical sensory input had a stronger effect than information provided before it. In summary, this dissertation contributes to the understanding of how individuals perceive and process information and how information influences their behavior. The insights from this dissertation can support individuals and society in the fight against fake news. Furthermore, it uncovered the manipulative power of specific characteristics of information. The insights from this dissertation provide a foundation for future research and practical applications in the realm of human information behavior.Publication News endorser influence in social media(2020) Teutsch, Doris; Trepte, SabineSocial networking sites have become an online realm where users are exposed to news about current affairs. People mainly encounter news incidentally because they are re-distributed by users whom they befriended or follow on social media platforms. In my dissertation project, I draw on shared reality theory in order to examine the question of how the relationship to the news endorser, the person who shares news content, determines social influence on opinion formation about shared news. The shared reality theory posits that people strive to achieve socially shared beliefs about any object and topic because of the fundamental epistemic need to establish what is real. Social verification of beliefs in interpersonal communication renders uncertain and ambiguous individual perceptions as valid and objectively true. However, reliable social verification may be provided only by others who are regarded as epistemic authority, in other words as someone whose judgment one can trust. People assign epistemic authority particularly to socially close others, such as friends and family, or to members of their in-group. I inferred from this that people should be influenced by the view of a socially close news endorser when forming an opinion about shared news content but not by the view of a socially distant news endorser. In Study 1, a laboratory experiment (N = 226), I manipulated a female news endorser’s social closeness by presenting her as an in-group or out-group member. Participants’ opinion and memory of a news article were not affected by the news endorser’s opinion in either of the conditions. I concluded that the news article did not elicit motivation to strive for shared reality because participants were confident about their own judgment. Therefore, they did not rely on the news endorser’s view when forming an opinion about the news topic. Moreover, the results revealed that participants had stronger trust in the news endorser when she expressed a positive (vs. negative) opinion about the news topic, while social closeness to the news endorser did not predict trust. On the one hand, this is in line with the social norm of sharing positive thoughts and experiences on social networking sites: adherence to the positivity norm results in more favorable social ratings. On the other hand, my findings indicate that participants generally had a positive opinion about the topic of the stimulus article and thus had more trust in news endorsers who expressed a similar opinion. In Study 2, an online experiment (N = 1, 116), I exposed participants to a news post by a relational close vs. relational distant news endorser by having them name a close or distant actual Facebook friend. There was a small influence of the news endorser’s opinion on participants’ thought and opinion valence irrespective of whether the news endorser was a close or distant friend. The finding was surprising, particularly because participants reported stronger trust in the view of the close friend than in the view of a distant friend. I concluded that in light of an ambiguity eliciting news article, people may even rely on the views of less trustworthy news endorsers in order to establish a socially shared and, therefore, valid opinion about a news topic. Drawing on shared reality theory, I hypothesized that social influence on opinion formation is mediated by news endorser congruent responses to a news post. The results indicated a tendency for the proposed indirect relation however, the effect size was small and the sample in Study 2 was not large enough to provide the necessary statistical power to detect the mediation. In conclusion, the results of my empirical studies provide first insights regarding the conditions under which a single news endorser influences opinion formation about news shared on social networking sites. I found limited support for shared reality creation as underlying mechanism of such social influence. Thus, my work contributes to the understanding of social influence on news perception happening in social networking sites and proposes theoretical refinements to shared reality theory. I suggest that future research should focus on the role of social and affiliative motivation for social influences on opinion formation about news shared on social networking sites.Publication The psychology of privacy: Analyzing processes of media use and interpersonal communication(2017) Dienlin, Tobias; Trepte, SabineWhat is the psychology of privacy? How do people perceive privacy? Why do people disclose personal information on the Internet, and what does this reveal about our their personalities? With four studies, this cumulative dissertation discusses potential answers to these questions. Study 1 (“The Privacy Process Model”) proposes a new privacy theory, the so-called Privacy Process Model (PPM). The PPM states that privacy consists of three major elements: the privacy context, the privacy perception, and the privacy behavior. In order to balance the three elements people constantly engage in a privacy regulation process, which can be either explicit/conscious or implicit/subconscious. Through concrete examples of new digital media, several implications of the PPM are demonstrated. Study 2 (“Is the Privacy Paradox a Relic of the Past?”), which is co-authored by Prof. Dr. Sabine Trepte, analyzes the privacy paradox through the results of an online questionnaire with 579 respondents from Germany. By adopting a theory of planned behavior-based approach, the results showed that self-disclosure could be explained by privacy intentions, privacy attitudes, and privacy concerns. These findings could be generalized for three different privacy dimensions: informational, social, and psychological privacy behaviors. Altogether, Study 2 therefore suggests that the privacy paradox does not exist. Study 3 (“An Extended Privacy Calculus Model for SNSs”), co-authored by Prof. Dr. Miriam J. Metzger, builds upon the results of Study 2 and investigates whether psychological antecedents can explain not only online self-disclosure but also online self-withdrawal. Using a privacy calculus-based approach, the study analyzes data from a U.S.-representative online sample with 1,156 respondents. The results showed that self-disclosure could be explained both by privacy concerns and expected benefits. In addition, self-withdrawal could also be predicted by both privacy concerns and privacy self-efficacy. In conclusion, Study 3 demonstrates that perceived benefits, privacy self-efficacy, and privacy concerns together predict both online self-disclosure and online self-withdrawal. Study 4 (“Predicting the Desire for Privacy”), also co-authored by Miriam J. Metzger, analyzes the relationship between the desire for privacy and different facets of personality. In Study 4a, an online questionnaire with 296 respondents was conducted and in Study 4b, a laboratory experiment with 87 participants was run. The results of the questionnaire showed several significant relationships: For example, respondents who reported lacking integrity and being more shy, less anxious, and more risk averse were all more likely to desire privacy. The experiment showed a statistical trend that participants who had written an essay about past negative behaviors were more likely to express an increased desire for privacy from other people; in addition, an implicit association test (IAT) showed that participants whose IAT results implied higher lack of integrity also desired more privacy from government surveillance. In conclusion, the results evidence that the desire for privacy relates with several aspects of personality and, notably, also with personal integrity. In the overarching discussion, the results of the aforementioned studies are combined in order to provide an updated picture of privacy. This picture suggests that online self-disclosure is not paradoxical but explainable. Being able to understand online privacy behaviors is important; however, this is not only because the Internet has paramount importance in social and professional contexts, but also because people’s desire for privacy can reveal central aspects of personality, such as one’s own personal integrity. Finally, several societal implications are discussed. It is argued that modern societies should try to design new cultural artifacts about privacy, update old and obsolete behavioral patterns with regard to privacy, foster a better understanding of the conceptual nature of privacy, work toward new and more protective privacy laws, and aim to leverage overall privacy literacy.Publication VERZERRT. SCHRILL. GESPALTEN. Meinungsklima und Diskursqualität im Internet und ihre Wirkungen auf den Journalismus(2022) Fulda, Stefanie; Schweiger, WolfgangJournalists play a dual role in shaping public opinion. On one hand, they influence public opinion through their publications. At the same time, they themselves continuously monitor public opinion and orient themselves to it. It seems obvious that the way journalists perceive the world can also influence their work. In fact, it has not yet been studied in terms of the perceived climate of opinion. It is similar with the perceived digital debate culture. Quality, tone and content of online discourses are already widely addressed under keywords such as incivility and hate speech. Effects on journalism are also mentioned, but they don´t focus on how journalists perceive the combined climate of opinion and quality of discourse and how this affects their work. In fact, user comments, individual opinions and opinion leaders are of particular importance to journalists in this perception. Due to the still incomplete state of research on the perception effects of public opinion and discourse quality on journalism, qualitative, guideline-supported interviews were therefore set up on the question "How do journalists perceive opinion climate and discourse quality on the Internet and how does this affect their work?" in order to approach the possible manifestations of this topic in an explorative manner. For these interviews, which lasted 1 - 1.5 hours, 20 journalists from all over Germany were interviewed. The net sample of participating journalists differed according to department, type of employment, age, location, gender, subject areas and degree of position, with the aim of obtaining answers from as many different journalists as possible and being able to compare the answers of certain groups with each other. In addition, a website was created as a central information point for the project. With the help of a repetitive change of perspective in the survey, which addresses the approach and considerations of the interviewees, but also inquires how, from the interviewees point of view, other journalists deal with the same issue, it was possible to identify some hidden perceptual effects. Beginning with the question about the central sources of public opinion perception, via processing and the mechanisms in this process, to the recognizable effects on journalistic work, it was thus possible to trace the path of perception of opinion climate and discourse quality to the effects on journalistic topic selection and topic processing. A key finding of the survey is that it remains unclear to the group of journalists surveyed whether the perceived climate of opinion on the Internet is representative of society as a whole - many do not rule out parallels of digital and general public opinion. At the same time, it is rationally clear to many journalists that they should not be too impressed by the experiences on the Net, since these represent only a small section of society, but emotionally it does happen - because the quality of the experienced, digital discourse is so impressive. On the other hand, almost all of the journalists surveyed assume that the perceived climate of opinion influences their journalistic work, but show a lack of clarity about the extent to which they are personally affected by this in their work. They do not know the concrete effects. Finally, it became obvious that journalists base their perception of public opinion quite significantly on the perceived quality of discourse. This is an understandable approach, but one that harbors the risk of misperceptions due to third person, negativity or false uniqueness effects, to name just a few of the most important potential distortions of perception. This has consequences: If those who report on public opinion are subject to a distorted perception, then they bring this into their reporting, which reinforces the tendency for recipients to also be subject to a distorted perception of public opinion. Citizens, in turn, express themselves in social media or below journalistic articles in the comments. These are read by editorial teams and in turn used for journalistic reporting. This is where the circle closes, because this is how recipients and journalists influence each others distorted perceptions and draw conclusions about public opinion in society. Minority opinions are perceived as majority opinions, the emotionally heated discourse on the Internet shapes the impression of a growing polarization of society, and journalism carries this idea into its reporting. The consequence is a possible misinterpretation of public opinion by journalistic media, so that journalism runs the risk of arguing past the actual public opinion of society through a distorted perception of public opinion and discourse quality on the Internet.
