On the causal relation between real world activities and emotional expressions of social media users

Abstract

Social interactions through online social media have become a daily routine of many, and the number of those whose real world (offline) and online lives have become intertwined is continuously growing. As such, the interplay of individuals' online and offline activities has been the subject of numerous research studies, the majority of which explored the impact of people's online actions on their offline activities. The opposite direction of impact—the effect of real‐world activities on online actions—has also received attention but to a lesser degree. To contribute to the latter form of impact, this paper reports on a quasi‐experimental design study that examined the presence of causal relations between real‐world activities of online social media users and their online emotional expressions. To this end, we have collected a large dataset (over 17K users) from Twitter and Foursquare, and systematically aligned user content on the two social media platforms. Users' Foursquare check‐ins provided information about their offline activities, whereas the users' expressions of emotions and moods were derived from their Twitter posts. Since our study was based on a quasi‐experimental design, to minimize the impact of covariates, we applied an innovative model of computing propensity scores. Our main findings can be summarized as follows: (a) users' offline activities do impact their affective expressions, both of emotions and moods, as evidenced in their online shared textual content; (b) the impact depends on the type of offline activity and if the user embarks on or abandons the activity. Our findings can be used to devise a personalized recommendation mechanism to help people better manage their online emotional expressions.

Understanding the effects of message cues on COVID‐19 information sharing on Twitter

“…Second, this study identified the impact of emotional valence on information sharing during public health crises. As suggested by ELM, audiences pay attention to emotional cues in a message (Petty & Cacioppo, 1986 ), especially for online discussions (Falavarjani et al, 2021 ). Our results show that different emotions may exert varying effects on social media information sharing.…”

A prediction model of users' attention transfer in the context of multitopic competition

“…The user features may have different effects on users' behavior and information dissemination on the social media platform (Falavarjani et al ., 2021). The user features selected in this study include the number of accounts followed by a user, number of followers, user category, user activity and initial topic attentiveness.…”

Is my doctor around me? Investigating the impact of doctors’ presence on patients’ review behaviors on an online health platform

“…The volume of online reviews, Volume it , was calculated as the number of doctor i's online reviews generated by their patients in the period t. As previously mentioned, we used review length to measure review effort. To construct the measures of review length and emotional expression, we used Linguistic Inquiry and Word Count (LIWC), which is a well-validated text analytics tool widely used in prior research (e.g., Cohan et al, 2017;Falavarjani et al, 2021;Huang et al, 2017). LIWC can accurately identify emotion in written language and capture people's social and psychological state (Tausczik & Pennebaker, 2010).…”
