Examining the Psychological Mechanisms Underlying Nostalgia Appeals: A Comparative Experiment of Nostalgia and Regret.

Obesity rates remain high among U.S. adults, especially rural residents. Research has shown that nostalgia appeals effectively promote several healthy behaviors. However, the psychological mechanisms underlying nostalgia appeals remain unclear. This study examined the effects of nostalgia appeals on intention to increase exercise and shed light on how nostalgia affected persuasive outcomes. We anticipated that nostalgia appeals would persuade people by enhancing self-esteem and reducing anger and counterarguing. To illuminate the mechanisms underlying the effects of nostalgia, a between-subject experiment (nostalgia appeal vs. regret appeal vs. irrelevant message vs. neutral persuasive message) was conducted among overweight or obese rural Michiganders (N = 507). Results showed that relative to the regret appeal, the nostalgia appeal led to higher state self-esteem, less anger, and less counterarguing. There was no significant difference in attitude or behavioral intention between the nostalgia appeal, regret appeal, and neutral persuasive message. We demonstrated that enhancing self-esteem was the key mechanism by which the nostalgia appeal persuaded the target audience.

Achieving Public Health Impact: Health Communication Research to Inform Tobacco Regulatory Science.

Health communication research applies communication science to develop generalizable knowledge capable of improving the health and well-being of individuals and communities. But to what extent does the knowledge generated by the health communication field actually achieve public health impact? To answer this question, we discuss the application of health communication science and research within a tobacco regulatory science framework. We describe three areas in which health communication research funded by the Food and Drug Administration (FDA) Center for Tobacco Products (CTP) contributed to 1) youth tobacco prevention campaigns, 2) cigarette health warnings, and 3) regulation of labeling, advertising, and marketing claims. These examples demonstrate how communication regulatory science achieves public health impact in the real world by informing national policies, regulatory actions, and public health practice.

The Role of Collective Group Orientation and Social Norms on Physical Distancing Behaviors for Disease Prevention.

To reduce the impact of communicable diseases like COVID-19, collective action is required and likely to be susceptible to normative influence as well as whether people are more or less collectively oriented. We extend the theory of normative social behavior (TNSB) to account for group orientation and predict the relationships between social norms and physical distancing behaviors. Using a rolling cross-sectional design during 17 weeks of the pandemic, a national sample of US residents from 20 states (N = 8,778) participated in the study. The findings show that perceived descriptive norms, injunctive norms, and group orientation are significantly associated with physical distancing. The descriptive norm-behavior relationship and injunctive norm-behavior relationship are moderated by group orientation and the other predicted moderators in the TNSB. The findings extend the TNSB and highlight the need to understand social norms and group orientation in formative research for health communication campaigns designed to promote prevention behaviors.

Characterizing the Relationship between Personality Dimensions and Psychosis-Specific Clinical Characteristics.

Background: Past studies associating personality with psychosis have been limited by small nonclinical samples and a focus on general symptom burden. This study uses a large clinical sample to examine personality's relationship with psychosis-specific features and compare personality dimensions across clinically and neurobiologically defined categories of psychoses. Methods: A total of 1352 participants with schizophrenia, schizoaffective disorder, and bipolar with psychosis, as well as 623 healthy controls (HC), drawn from the Bipolar-Schizophrenia Network for Intermediate Phenotypes (BSNIP-2) study, were included. Three biomarker-derived biotypes were used to separately categorize the probands. Mean personality factors (openness, conscientiousness, extraversion, agreeableness, and neuroticism) were compared between HC and proband subgroups using independent sample t-tests. A robust linear regression was utilized to determine personality differences across biotypes and diagnostic subgroups. Associations between personality factors and cognition were determined through Pearson's correlation. A canonical correlation was run between the personality factors and general functioning, positive symptoms, and negative symptoms to delineate the relationship between personality and clinical outcomes of psychosis. Results: There were significant personality differences between the proband and HC groups across all five personality factors. Overall, the probands had higher neuroticism and lower extraversion, agreeableness, conscientiousness, and openness. Openness showed the greatest difference across the diagnostic subgroups and biotypes, and greatest correlation with cognition. Openness, agreeableness, and extraversion had the strongest associations with symptom severity. Conclusions: Individuals with psychosis have different personality profiles compared to HC. In particular, openness may be relevant in distinguishing psychosis-specific phenotypes and experiences, and associated with biological underpinnings of psychosis, including cognition. Further studies should identify potential causal factors and mediators of this relationship.
