Considering that insufficient sleep has long been regarded as a significant public health challenge, the COVID-19 pandemic and its co-evolving infodemic have further aggravated many people's sleep health. People's engagement with pandemic-related news, particularly given that many people are now permanently online via smartphones, has been identified as a critical factor for sleep health, such that public health authorities have recommended limited news exposure. This two-wave panel survey, conducted with a representative sample in Austria during its first COVID-19 lockdown, examines (a) how fear of missing out on pandemic-related news (i.e., COVID-19 information FOMO) is reciprocally related to smartphone-based bedtime news engagement, as well as (b) how both bedtime news engagement and COVID-19 information FOMO predict daytime tiredness. Partial metric measurement invariant structural equation modeling revealed that COVID-19 information FOMO and bedtime news engagement are reciprocally associated over time, indicating a potentially harmful reinforcing loop. However, results further suggested that COVID-19 information FOMO may be the primary driver of daytime tiredness, not smartphone-based bedtime news engagement. These findings suggest that a perceived loss of (informational) control over the pandemic outbreak more strongly than poor sleep habits accounts for depleted energy resources during lockdown. However, given the initial evidence for a reinforcing loop, this effect pattern may change in the long term.

Advertising frequently promotes environmentally detrimental consumption choices such as air travel. To date, the effects of these ads on individuals' moral evaluation of unsustainable behaviors are still little understood. This study with a quota-based sample in Germany (N = 199) explored whether individuals morally disengage from the harmfulness of flying due to ad exposure. Based on the theory of moral disengagement (Bandura, 2016, Moral disengagement: How people do harm and live with themselves. Worth Publishers), we investigated whether individuals neglect negative consequences, seek moral justification or displace responsibility for flying behaviors after seeing flight advertising. The results suggested that individuals low in climate change concern become more neglectful of the consequences of flying, while climate change concerned individuals exhibited the opposite reaction. Irrespective of individuals' level of climate change concern, ad exposure increased recipients' displacement of responsibility to other actors. Moreover, we found a correlation between mechanisms of moral disengagement and flying intentions as well as support for aviation policies.

For many individuals, the media function as a primary source of information about preventative measures to combat COVID-19. However, a considerable number of citizens believe that the media coverage about pandemics is exaggerated. Although the perception of media exaggeration may be highly consequential for individual health behaviors, we lack research on the drivers and consequences of this perception. In a two-wave panel study, we examined associations between trust in science, perceptions of media exaggeration about COVID-19, and social distancing behavior during the lockdown in Austria (NT2 = 416). Results showed that trust in science at T1 led to less perceptions of media exaggeration about COVID-19 at T2. Furthermore, consistent with the theory of psychological reactance, perceptions of media exaggeration about COVID-19 at T1 caused less social distancing behavior at T2. Thus, findings suggest that trust in science may positively affect individuals' social distancing behavior by decreasing perceived media exaggeration about COVID-19 over time. Implications for research on media effects in times of COVID-19 and conclusions for journalists are discussed.

Background Given that governmental prevention measures restricted most face-to-face communications, online self-disclosure via smartphones emerged as an alternative coping strategy that aimed at reducing the impact of the COVID-19 pandemic on people’s psychological health. Prepandemic research demonstrated that online self-disclosure benefits people’s psychological health by establishing meaningful relationships, obtaining social support, and achieving self-acceptance, particularly in times of crisis. However, it is unclear whether these dynamics transition well to lockdown conditions where online self-disclosure must stand almost entirely on its own. Longitudinal investigations are needed to gain insights into the psychological functionalities of online self-disclosure during the COVID-19 pandemic. Objective This study aimed to determine the temporal associations between smartphone online self-disclosure (as a communicative behavior) and critical indicators of psychological health (including psychopathological, as well as hedonic and eudaimonic states) during the first COVID-19 lockdown in Austria. Methods We conducted a representative 2-wave panel survey between late March/April 2020 and May 2020. A total of 416 participants completed both waves (43.1% attrition rate, given n=731 participants who completed the first wave). A partially metric measurement invariant overtime structural equation model was used to determine the temporal associations among online self-disclosure, fear of COVID-19, happiness, and psychological well-being. Results The analysis revealed that fear of COVID-19 significantly predicted online self-disclosure over time (b=0.24, P=.003) and happiness over time (b=−0.14, P=.04), but not psychological well-being (b=0.03, P=.48), that is, stronger COVID-19 fears at T1 prompted more online self-disclosure and less happiness at T2. Online self-disclosure, on the other hand, significantly predicted happiness (b=0.09, P=.02), but neither fear of COVID-19 (b=−0.01, P=.57) nor psychological well-being (b=−0.01, P=.57) over time. Participants who engaged more strongly in online self-disclosure at T1 felt happier at T2, but they did not differ from less-disclosing participants concerning COVID-19 fears and psychological well-being at T2. Importantly, happiness and psychological well-being were significantly related over time (happiness T1 → psychological well-being T2: b=0.11, P<.001; psychological well-being T1 → happiness T2: b=0.42, P<.001). Conclusions Our findings suggest that online self-disclosure might play a pivotal role in coping with pandemic stressors. With restrictions on their options, individuals increasingly turn to their smartphones and social media to disclose their feelings, problems, and concerns during lockdown. While online self-disclosure might not alleviate fears or improve psychological well-being, our results demonstrate that it made people experience more happiness during this crisis. This psychological resource may help them withstand the severe psychological consequences of the COVID-19 crisis over longer timeframes.
