Measuring Parasocial Processing
Research on parasocial phenomena is thriving, and parasocial processing emerged as a key concept in the wake of this trend. In this paper, we derive and systematically test a shortened version of the central measure of parasocial processing, the PSI-Process Scales. The theoretically grounded Parasocial Processing Short Scale (PP-SS) consists of only nine items. The scale was systematically developed and validated in two preregistered empirical st…
Nudges for news recommenders
News aggregators inherently constitute choice architectures in which placement and presentation of news articles in the user interface affect how people perceive and engage with them. Accordingly, deliberate changes of a news aggregators’ choice architecture may nudge engagement. Against this background, our study aims to test the effects of 2 nudges, namely a position and an accessibility nudge, on (a) the selection of, (b) the engagement with, …
Nudging News Readers
Building on research on nudging as well as democratic news recommender design, this preregistered study employed a mixed-methods design to explore how interface nudges and article positioning affect news selection. Specifically, we tested whether a position nudge as well as three different types of interface nudges (e.g., popularity cues and social norm interventions) can facilitate readers’ engagement with current affairs news over other genres.…
It ain't easy
Proponents of ‘democratic news recommender design’ argue that algorithmic news diversification may facilitate democratic participation. However, while various news diversification metrics have been proposed in recent years, few of them have been put to the test with real users. To assess the promises and pitfalls of algorithmic news diversification, we conduct a 2 (low vs. high levels of activating language) by 3 (low vs medium vs high levels of …
Comparative privacy research
The ways in which privacy is understood, defined, perceived, and enacted are contingent on cultural, social, political, economic, and technological settings. Yet, privacy research is often criticized for not adequately accounting for these. A comparative perspective requires the contextualization of privacy through investigating similarities and differences across contexts. This article outlines the Comparative Privacy Research Framework, which i…
Escaping the digital panopticon? Longitudinal effects of dataveillance salience shocks on privacy attitudes and inhibited behaviors
Using internet technologies exposes individuals to constant surveillance by companies and other actors. Perceptions of constant surveillance—termed “dataveillance”—are theorized to induce chilling effects (i.e., inhibiting legal and legitimate online activities) posing risks to individuals and societies. In this preregistered longitudinal 3-wave experiment (N = 774), we investigate whether news articles addressing constant online surveillance ind…

Recognizing the importance of privacy in today's digital societies and volatile political and regulatory environments, the editorial highlights the pressing need for comparative research on the topic and describes the articles in this special issue. The special issue addresses the theoretical, methodological, and practical challenges a…
Examining learners' engagement patterns and knowledge outcome in an experiential learning intervention for youth's social media literacy
Social media have become an integral part of youth's daily lives. Though it brings many benefits such as creative self-expression and opportunities for social connection and support, studies have revealed that exposure to cyberbullying, misinformation and disinformation, or phishing and scams pose great risks to youth's mental health and long-term development. There is no lack of education programs designed to teach youth media literacy, but very…
Direct Replication in Experimental Communication Science
Replication is generally considered a keystone of the scientific enterprise. Unfortunately, in communication science, there is a lack of clarity on what a replication actually entails, and to what extent replicators may deviate from original studies. In order to support researchers in conducting, evaluating, and justifying the setup of replications of communication science experiments, we provide a taxonomy of replication types. We argue that res…
The youth social media literacy inventory
Social media has opened new doors of opportunities and risks for youth. Potential risks include exposure to harmful content, engagement with strangers, or unwanted consequences from irresponsible or naive use. Social media literacy has been proposed as a way to mitigate such risks and promote positive ways of social media engagement. This paper aimed to develop a comprehensive Youth Social Media Literacy Inventory (YSMLI) to objectively assess yo…
Understanding the effects of conceptual and analytical choices on ‘finding’ the privacy paradox
The privacy paradox suggests that privacy concerns do not relate to privacy-related behavior. Although it has inspired numerous studies, findings remain inconclusive. Some of the inconsistencies in published findings may be explained by a strong heterogeneity in the conceptual and analytical choices that researchers implement when investigating the privacy paradox. Based on representative survey data of the 27 EU member states (2011: n = 8,962; 2…
The Routledge Handbook of Privacy and Social Media
This volume provides the basis for contemporary privacy and social media research and informs global as well as local initiatives to address issues related to social media privacy through research, policymaking, and education. Renowned scholars in the fields of communication, psychology, philosophy, informatics, and law look back on the last decade of privacy research and project how the topic will develop in the next decade. The text begins with…
The Impact of What Others Do, Approve Of, and Expect You to Do
There are many factors that account for disclosure of private information on social network sites, but a potentially powerful determinant that remains understudied is social norms, which refer to perceptions of what other people do, approve of, and expect us to do on social media. To address this gap, we conducted an in-depth analysis of descriptive, injunctive, and subjective norms for verbal and visual disclosure on Facebook and Instagram, usin…
Nudging towards news diversity
Growing concern about the democratic impact of automatically curated news platforms urges us to reconsider how such platforms should be designed. We propose a theoretical framework for personalised diversity nudges that can stimulate diverse news consumption on the individual level. To examine potential benefits and limitations of existing diversity nudges, we conduct an interdisciplinary literature review that synthesises theoretical work on new…
Learning by doing oder doing by learning? Die Wechselwirkung zwischen Online- Privatheitskompetenz und Datenschutzverhalten
Die Nutzung von und die Kommunikation mit sozialen Medien basiert auf dem Austausch persönlicher Daten. Dabei können Privatheitsrisiken entstehen, vor denen man sich oft nur schwer schützen kann. Damit Menschen Online-Angebote selbstbestimmt nutzen können, ist ein gewisser Schutz ihrer Daten erforderlich. Immer häufiger wird die Online-Privatheitskompetenz als Voraussetzung dafür angesehen. Kritisch hinterfragt wird jedoch, ob Wissen über Online-…
Transformative or Not? How Privacy Violation Experiences Influence Online Privacy Concerns and Online Information Disclosure
Previous research has shown that people seldom experience privacy violations while using the Internet, such as unwanted and unknown sharing of personal information, credit card fraud, or identity theft. With this study, we ask whether individuals’ online privacy concerns increase and online information disclosure decreases if they experience such a worst-case scenario. Using representative data from a five-wave panel study (n = 745), we found tha…
Development and Validation of an Algorithm Literacy Scale for Internet Users
In light of the widespread use of big data analytics, internet users are increasingly confronted with algorithmic decision-making. Developing algorithm literacy is thus crucial to empower users to successfully navigate digital environments. In this paper, we present the development and validation of an algorithm literacy scale that consists of two interrelated dimensions: 1) awareness of algorithms use and 2) knowledge about algorithms. To valida…
A longitudinal analysis of the privacy paradox
The privacy paradox states that people’s concerns about online privacy are unrelated to their online sharing of personal information. On the basis of a representative sample of the German population, which includes 1,403 respondents interviewed at three waves separated by 6 months, we investigate the privacy paradox from a longitudinal perspective. Using a cross-lagged panel model with random intercepts, we differentiate between-person relations …
How Online Privacy Literacy Supports Self-Data Protection and Self-Determination in the Age of Information
Current debates on online privacy are rooted in liberal theory. Accordingly, privacy is often regarded as a form of freedom from social, economic, and institutional influences. Such a negative perspective on privacy, however, focuses too much on how individuals can be protected or can protect themselves, instead of challenging the necessity of protection itself. In this article, I argue that increasing online privacy literacy not only empowers in…

The Impact of Internet and Social Media Use on Well-Being
The present research examines the longitudinal average impact of frequency of use of Internet and social networking sites (SNS) on subjective well-being of adolescents in Germany. Based on five-wave panel data that cover a period of nine years, we disentangle between-person and within-person effects of media use on depressive symptomatology and life satisfaction as indicators of subjective well-being. Additionally, we control for confounders such…
Psychological predictors of political Internet use and political knowledge in light of the perceived complexity of political issues
In the era of the Internet, political communication becomes increasingly complex due to an abundance of available information. Moreover, many people evaluate politics as complex in a globalized world. The present study examined whether the perceived complexity of political issues would be related to individuals’ political Internet use and political knowledge. Further, we investigated the associations of three key psychological concepts with polit…
Situational Privacy and Self-Disclosure
Privacy in Mediated and Nonmediated Interpersonal Communication
New communication media such as social networking sites (SNSs) and instant messengers (IMs) challenge users' privacy perceptions. Technical infrastructures and the flow of digital information lead to novel privacy risks that individuals are often not acquainted with. Users' subjective perceptions of privacy may thus be flawed and lead to irrational behavior. In this work, we investigated a concept that has been addressed only implicitly in academ…
Reinforcement or Displacement? The Reciprocity of FtF, IM, and SNS Communication and Their Effects on Loneliness and Life Satisfaction
Does communication on social network sites (SNSs) or instant messengers (IMs) reinforce or displace face-to-face (FtF) communication, and how do the 3 channels affect loneliness and life satisfaction? Using cross-lagged structural equation modeling in a longitudinal and representative sample from Germany, we found that SNS communication increased both FtF and IM communication 6 months later. Likewise, IM communication at T1 increased SNS communic…

Disclosure Management on Social Network Sites
The social web and specifically social network sites (SNS) have offered new opportunities for interaction and communication, but have also increased the risk of privacy violations. In this study, we investigated how far users imply different disclosure management strategies in status updates and chat conversations. We hypothesized that users perceive specific information as differently private depending on their personal privacy preference, but g…
