This study investigates how parents manage conflicting online information, which may affect their information-seeking behavior and decision-making about childhood vaccination, by applying the Theory of Motivated Information Management in online communication contexts. Although an extensive body of literature has demonstrated the effectiveness of TMIM in predicting how individuals manage health uncertainty and information in the interpersonal communication contexts, the present study goes beyond and applies the theoretical framework in the online communication contexts. Our findings of a survey with 439 parents in the United States are in conjunction with previous applications of TMIM, which show that individuals adopt a similar process to deal with uncertainty resulting from conflicting information in the online environment. Although further research must be conducted to change perceptions, attitudes, and vaccine-related behaviors, this study may help communication practitioners, vaccination advocates, and related nonprofit organizations to eliminate misconceptions about immunization among parents.

Purpose: The purpose of this paper is to apply communication theory to explore and help explain public support for causes and organizations in the form of prosocial behaviors, including donating, volunteering and participating in advocacy efforts. Design/methodology/approach: Through a survey of people (n=1,275) living in the USA who indicated supporting issues they cared about in 2017, this research gathered information about motivations for providing public support for various causes and non-profit organizations. Findings: The situational theory of problem solving (STOPS) was applied, and support was found for the STOPS model in terms of predicting communicative action. This study also found support for situational activeness influencing other behaviors, including active forms of communication, financial support, volunteer support and other forms of advocacy. Implications for practitioners managing communications or organizations involved in such efforts are discussed. Originality/value: This research applied STOPS to study behaviors, including communication, volunteering, donating and participating in advocacy efforts as forms of prosocial behavior supporting different organizations related to many important issues. The paper provides theoretical value in terms of adding to the generalizability of the STOPS model for communications scholars and discusses practical implications for non-profit and other types of organizations.

Despite increasing warnings about inaccurate information online, little is known about how social media contribute to the widespread diffusion of unverified health information. This study addresses this issue by examining the vaccine-autism controversy. By looking into a large dataset of Twitter, Reddit posts, and online news over 20 months in the US, Canada, and the UK, our time-series analysis shows that Twitter drives news agendas, and Reddit follows news agendas regarding the vaccine-autism debate. Additionally, the results show that both Twitter and Reddit are more likely to discuss the vaccine-autism link compared to online news content. [ABSTRACT FROM AUTHOR]

In a randomized between-subjects design, participants (N = 80) were assigned to one of four conditions, 2 (pregnant, not pregnant) × 2 (extreme prime, moderate prime). It was hypothesized that primes involving moderate mental illness would be positively associated with increased perceived risk of developing postpartum depression. Hayes and Preacher's bootstrapping procedure was used to test the direct, indirect, and conditional indirect effects related to the hypothesized model. In addition, further analyses evaluated whether implicitly activated goals (to be healthy or to be a good mother) were positively associated with increased perceptions of risk and engagement of downstream avoidance behavioral intentions. Findings show that for pregnant participants, the effect of the prime condition on perceived personal risk of developing postpartum depression was mediated by perceptions about the target character's sanity. However, activated "healthy" and "good mother" goals are not influencing behavioral intentions. [ABSTRACT FROM AUTHOR]

Objective: Some researchers have raised concerns that pictorial health warning labels (HWLs) on cigarette packages may lead to message rejection and reduced effectiveness of HWL messages. This study aimed to determine how state reactance (i.e., negative affect due to perceived manipulation) in response to both pictorial and text-only HWLs is associated with other types of HWL responses and with subsequent cessation attempts. Methods: Survey data were collected every 4 months between September 2013 and 2014 from online panels of adult smokers in Australia, Canada, Mexico, and the US were analyzed. Participants with at least one wave of follow-up were included in the analysis (n = 4,072 smokers; 7,459 observations). Surveys assessed psychological and behavioral responses to HWLs (i.e., attention to HWLs, cognitive elaboration of risks due to HWLs, avoiding HWLs, and forgoing cigarettes because of HWLs) and cessation attempts. Participants then viewed specific HWLs from their countries and were queried about affective state reactance. Logistic and linear Generalized Estimating Equation (GEE) models regressed each of the psychological and behavioral HWL responses on reactance, while controlling for socio-demographic and smoking-related variables. Logistic GEE models also regressed having attempted to quit by the subsequent survey on reactance, each of the psychological and behavioral HWL responses (analyzed separately), adjustment variables. Data from all countries were initially pooled, with interactions between country and reactance assessed; when interactions were statistically significant, country-stratified models were estimated. Results: Interactions between country and reactance were found in all models that regressed psychological and behavioral HWL responses on study variables. In the US, stronger reactance was associated with more frequent reading of HWLs and thinking about health risks. Smokers from all four countries with stronger reactance reported greater likelihood of avoiding warnings and forgoing cigarettes due to warnings, although the association appeared stronger in the US. Both stronger HWLs responses and reactance were positively associated with subsequent cessation attempts, with no significant interaction between country and reactance. Conclusions: Reactance towards HWLs does not appear to interfere with quitting, which is consistent with its being an indicator of concern, not a systematic effort to avoid HWL message engagement.

This study investigated vaccine acceptance of putative COVID-19 vaccines among a national sample of vaccine hesitant parents. Vaccine hesitancy and politicization of vaccine development has led to a pronounced distrust of COVID-19 vaccines in the U.S. A total of 1,381 vaccine-hesitant parents participated in this study. Participants indicated a general unwillingness to vaccinate their children ( M = 3.55, SD  = 2.13) and themselves ( M = 3.58, SD  = 2.16) when a COVID-19 vaccine becomes available. More educated parents were more likely to plan to vaccinate themselves [ F (5, 533) = 9.93, p < .05] and their children [ F (5, 533) = 10.278, p < .05]. Understanding vaccine hesitant parents offers crucial insights as a COVID-19 vaccine becomes available for the general public and as we wait for a vaccine to be approved for pediatric use.
