Trading Data for Health

mHealth apps are growing in popularity among smartphone users. Such apps often contain social features that enable users to compare their behavior with others but to function, mHealth apps require users to share health information which is considered a threat to individuals’ privacy. Building on social comparison theory and research on privacy decision-making, we investigate the effects of users’ social comparison orientation and privacy attitudes as well as the potential mediating effect of health information disclosure on users’ intention to use a dietary app. Relying on a PLS-based structural-equation model in a sample of N = 528 participants, our study supports claims of a positive effect of social comparison orientation on intention to use a mHealth app. Further, the negative effect of privacy attitude and the positive mediation of information disclosure were supported as well. The study also demonstrated that findings were stable when the context of information disclosure is changed.

Do prior knowledge, model-observer similarity and social comparison influence the effectiveness of eye movement modeling examples for supporting multimedia learning?

We investigated in an experiment with 180 university students the joint role of prior knowledge, alleged model competence, and social comparison orientation regarding the effectiveness of Eye Movement Modeling Examples (EMME) for supporting multimedia learning. EMME consisted of short videos with gaze replays of an instructed model demonstrating effective multimedia processing strategies. Participants were either instructed that the model in the EMME-videos was a successful learner (competent model) or another participant (peer model). Participants in a control condition received no EMME. Furthermore, we activated domain-relevant prior knowledge in half of the participants before watching the EMME. Against our expectations, we found no influence of either prior knowledge activation or model-observer similarity. As expected, our results indicated that EMME fostered multimedia learning. This was also supported by findings from small-scale meta-analyses that were conducted with the focus on the effect of EMME for multimedia learning and potential moderators of the effect. Moreover, results showed first evidence that social comparison orientation interacts with (alleged) model competence regarding the effectiveness of EMME. Further research is needed to follow up on the influence of individual factors as well as social cues on the effectiveness of EMME.

Social Comparison Orientation and Cyberbullying Perpetration and Victimization: Roles of Envy on Social Networking Sites and Body Satisfaction

Although some studies have explored the psychological and behavioral outcomes of social comparison orientation (SCO), few have explored the associations of SCO with cyberbullying perpetration and victimization. The current study aimed to investigate the associations of SCO with cyberbullying perpetration and victimization, and considered envy on social networking sites (SNS) as a mediator and body satisfaction as a moderator in these relations. To test our expectations, 941 adolescents aged between 10 and 16 years ( M = 13.15, SD = 1.18) completed multiple questionnaires, namely the Social Comparison Orientation Scale, the Revised Cyber Bullying Inventory, an envy scale revised for the SNS context, and the Body Areas Satisfaction Scale. Correlation analysis revealed that cyberbullying perpetration and cyberbullying victimization were significantly and positively correlated with SCO and envy on SNS, and significantly and negatively correlated with body satisfaction. The results of structural equation modeling (SEM) revealed that envy on SNS played a mediating role in the associations of SCO with cyberbullying perpetration and victimization. The results of SEM and simple slope test analysis indicated that body satisfaction weakened the direct association of SCO with envy on SNS and further weakened the indirect associations of SCO with cyberbullying perpetration and victimization via envy on SNS. Specifically, individuals with high levels of SCO were more likely to feel envious on SNS, and further tended to bully others and be bullied online when they were dissatisfied with their bodies. In other words, positive body satisfaction protected individuals with high levels of SCO from cyberbullying perpetration and victimization by decreasing their feelings of envy on SNS.

Social Comparison and Stress Appraisal in Women with Chronic Illness

(1) Background: The present study examined how social comparison orientation, stress appraisal and different social comparison strategies interact in women facing chronic illness. (2) Methods: Assessments were conducted by a trained professional in face-to face semistructured interviews (n = 179 women with chronic illness). Main outcome measures included social comparison scales and a stress appraisal questionnaire. The mediation model, by a bootstrapping procedure, was used to analyze the interaction among variables. (3) Results: Regarding the relationships among variables studied, they were related to each other except for a downward contrast, which allowed us to propose our hypothetical mediation model. Results showed that stress appraisal fully mediates between social comparison orientation and social comparison strategies except for the upward identification strategy. (4) Conclusions: Our results suggest that uncertainty, feelings of threat and low control over one’s illness or, in general, stress appraisal, had an important mediating effects over social comparison processes in patients with chronic illnesses. Therefore, by understanding the stress appraisal process, and the variables that might modify it, we could improve the use of social comparison as a favorable coping strategy.
