Causal effects of point-of-sale cigarette promotions and subjective social status on cigarette craving: a randomised within-person experiment.

BACKGROUND: Cigarette smoking continues to be a leading cause of preventable deaths in the USA, in part because the USA has not adopted the WHO Framework Convention on Tobacco Control. One way the tobacco industry counteracts tobacco control policies is by heavily advertising cigarettes at the point of sale in retailers (eg, at the cash register) and by offering discounts on cigarettes. DESIGN: A within-subject experimental design with adults who smoke cigarettes daily (n=281) investigated whether: (1) exposure to images of cigarette promotions in an online experiment is associated with greater cigarette craving relative to viewing images of non-smoking cues, and (2) if exposure to images of point-of-sale cigarette promotions with a discount (vs without) increases cigarette craving. The study also examined how participants' subjective social status (compared with others in the USA) relates to cigarette craving after exposure to images of cigarette promotions with and without a discount. RESULTS: In an online experiment, exposure to images of smoking cues, including point-of-sale cigarette promotions, elicited greater craving relative to non-smoking cues (all p<0.001). In addition, images of promotions with a discount elicited higher levels of craving compared with those without a discount (b=0.09, p=0.001). Although participants with a higher (vs lower) subjective social status craved cigarettes less overall (b=-0.12, p=0.012), there was no difference in their craving between images of promotions with and without a discount, while craving was higher for images of promotions with a discount than without for participants with higher subjective social status (b=0.06, p=0.021). CONCLUSION: Viewing images of point-of-sale cigarette promotions can causally increase cravings to smoke, which may also apply to real-world retail settings that display cigarette promotions. Restricting point-of-sale promotions generally, and discounts specifically, could help reduce cigarette smoking and address tobacco use disparities in the USA.

Neural signals predict information sharing across cultures.

Information sharing influences which messages spread and shape beliefs, behavior, and culture. In a preregistered neuroimaging study conducted in the United States and the Netherlands, we demonstrate replicability, predictive validity, and generalizability of a brain-based prediction model of information sharing. Replicating findings in Scholz et al., Proc. Natl. Acad. Sci. U.S.A. 114, 2881-2886 (2017), self-, social-, and value-related neural signals in a group of individuals tracked the population sharing of US news articles. Preregistered brain-based prediction models trained on Scholz et al. (2017) data proved generalizable to the new data, explaining more variance in population sharing than self-report ratings alone. Neural signals (versus self-reports) more reliably predicted sharing cross-culturally, suggesting that they capture more universal psychological mechanisms underlying sharing behavior. These findings highlight key neurocognitive foundations of sharing, suggest potential target mechanisms for interventions to increase message effectiveness, and advance brain-as-predictor research.

Message self and social relevance increases intentions to share content: Correlational and causal evidence from six studies.

Information sharing within social networks can catalyze widespread attitudinal and behavioral change and the chance to share information with others has been characterized as inherently valuable to people. But what are the sources of value and how might they be leveraged to promote sharing? We test ideas from the value-based virality model that the value of sharing increases when people perceive messages as more relevant to themselves and to people they know, resulting in stronger intentions to share. We extend this work by considering how sharing context-broadcasting to a wide audience or narrowcasting directly to someone-may alter these relationships. Six online studies with adults in the United States (N participants = 3,727; messages = 362; message ratings = 30,954) showed robust evidence that self and social relevance are positively and uniquely related to sharing intentions within- and between-person. Specification curve analysis showed these relationships were consistent across message content (COVID-19, voting, general health, climate change), medium (social media post and news articles), and sharing context (broad- and narrowcasting). A preregistered experiment showed that manipulating the self and social relevance of messages through a framing manipulation causally increased sharing intentions. These causal effects were mediated by changes in both self and social relevance, but the relative strength of the causal pathways differed depending on sharing context. These findings extend existing models of information sharing, and highlight self and social relevance as psychological mechanisms that motivate information sharing that can be targeted to promote sharing across contexts.

Purpose in Life, Loneliness, and Protective Health Behaviors During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Social distancing, while effective in slowing the spread of the coronavirus disease 2019 (COVID-19), can increase social isolation. The current preregistered study examined purpose in life as a psychological resource that may buffer against loneliness and increase intentions to engage in health-protective behaviors. RESEARCH DESIGN AND METHODS: During the COVID-19 pandemic, 517 adults (mean = 37.71, SD = 11.30; range = 19-73) reported their levels of purpose in life, current and prepandemic levels of loneliness, and degrees to which they intended to engage in behaviors known to prevent the spread of COVID-19. RESULTS: Across age, having a stronger sense of purpose in life was associated with lower loneliness, as well as greater intentions to engage in COVID-protective behaviors. Higher loneliness was associated with lower intentions to maintain social distance and engage in additional health promotion behaviors such as handwashing. However, this link was not present at higher levels of purpose in life. Older age was also associated with less loneliness, but not for individuals with lower levels of purpose in life. DISCUSSION AND IMPLICATIONS: Results suggest that psychological resources such as purpose in life are associated with increased protective health behaviors. Furthermore, purpose in life may reduce loneliness and counteract the negative effects of stressors that diminish the willingness to engage in health-protective behaviors. Our data also highlight resilience among older individuals in times of isolation during a global pandemic.
