Vaping in a Time of Pandemics: Risk Perception and Motivations for Electronic Cigarette Use.

INTRODUCTION: prior studies on the association between the intensity of and motives for vaping e-cigarettes have highlighted the psychological dynamics of motivational changes, but less about how vaping motives may shift as a function of risk perceptions exacerbated by unanticipated events. This study frames the COVID-19 pandemic as an exacerbating threat to pulmonary health, and tests how e-cigarette users' risk perceptions of COVID-19 are related to different motives for vaping and ultimately the intensity of e-cigarette use. METHODS: an online survey of e-cigarette users in the U.S. (n=562) was conducted during April 2020 when much of the U.S. was under "lockdown" conditions. We distinguished three types of vaping motives (health, socialization, and dependence) and established the classification with confirmatory factor analysis. Structural equation modeling was conducted for path analyses and mediation tests. RESULTS: all three vaping motives were significantly associated with greater use intensity. A heightened risk perception of e-cigarette users' vulnerability to COVID-19 was inversely associated with use intensity (-.18, p<.01) and health motives for vaping (-.27, p<.001), but not associated with socialization and dependence motivations. Health motives for vaping mediated 35% of the association between COVID-19 risk perceptions and use intensity. CONCLUSIONS: our findings indicate that risk perceptions of exacerbated threats may reduce e-cigarette use directly, and also indirectly through shifting certain types of motivations for vaping. Beyond elucidating the relational dynamics between vaping psychology and health risks, these results also indicate health professionals may leverage the pandemic to promote nicotine cessation or reduced use. IMPLICATION: Little is known about how vaping motives shift after unanticipated events such as pandemics. This study contributes to knowledge of how the use of e-cigarettes is motivated by different dimensions of rationales and exogenous risks. Exploiting the emergence of the COVID-19 pandemic, we found risk perceptions are associated with the intensity of e-cigarette use indirectly specifically through health motivations. Risk perceptions are not associated with socialization and dependence motives for vaping.

Perceived Beliefs, Uncertainty, and Behavioral Responses During the COVID-19 Outbreak in China: Findings From a Convenience Sample.

PURPOSE: To investigate perceived beliefs, uncertainty, and behavioral responses among Chinese residents toward the COVID-19 outbreak, and explore their relationships amid an incipient pandemic. DESIGN: A cross-sectional correlational survey with a combination of a convenience and snowball sampling design. SETTING: This study was conducted online from February 7 to 14, 2020, the third week after the lockdown of Wuhan city on January 23. PARTICIPANTS: A total of 2,654 residents was contacted, 2,534 agreed to participate, and 2,215 completed valid questionnaires. The sample covered 30 provinces, municipalities, autonomous regions of China, and a broader region. MEASURES: The Uncertainty About COVID-19 Scale was applied to assess perceived public uncertainty. Five dimensions of health beliefs about COVID-19 and 12 health-related response behaviors were measured. ANALYSIS: Univariate analysis and multiple linear regression models were used to identify associations. Mediation was assessed by a bootstrapping technique. RESULTS: Five constructs of health beliefs were found to be significant predictors of multiple response behaviors. Uncertainty about COVID-19 has a direct relationship with general response behaviors (ß=-0.119**) and sanitization practices (ß=-0.068**). Emergency coping behaviors aside, uncertainty also partially mediated associations between perceived susceptibility, perceived effectiveness, and perceived barriers influencing general response behaviors and sanitization practices, respectively. CONCLUSION: Findings provide evidence-based information to government and policymakers for designing effective health communication messages and intervention strategies by targeting the key constructs of the health belief model and reducing perceived uncertainty about COVID-19. They support public health-related response behaviors to prevent COVID-19 spread among the population.

Uncertainty Stress, and Its Impact on Disease Fear and Prevention Behavior during the COVID-19 Epidemic in China: A Panel Study.

Objectives: We examined changing trends of uncertainty stress, and its impact on disease fear and prevention behaviors during the Chinese COVID-19 epidemic, using a prospective observational study. Methods: We employed a longitudinal design. We recruited participants for an online panel survey from chat groups on social media platforms. There were 5 waves of interviews. Information on uncertainty stress and related variables were collected via the online survey. Descriptive statistics and the GIM program were used for data analysis. Results: Participants numbered 150 for the linkable baseline survey and 102 (68%) for the final survey. Uncertainty stress (ß = -.047, SE = .118, p > .05) did not show a statistically significant temporal change trend over the observation period. Disease fear manifested a statistically significant downwards trend (ß = -.342, SE = .157, p < .05), and prevention behaviors indicated an upwards trend (ß = .048, SE = .021, p < .05) during the observation period. Uncertainty stress was positively associated with disease fear (ß = .45046, SE = .05964, p < .001), and negatively associated with self-efficacy (ß = -.6698, SE = .01035, p < .001), and prevention behaviors (ß = -.02029, SE = .00876, p =.021). Conclusion: This study yielded new information about uncertainty stress among Chinese people during the COVID-19 epidemic. Policy changes and public education are essential for minimizing the negative effects of uncertainty stress in disease prevention.

Changing trends of mental and behavioral responses and associations during the COVID-19 epidemic in China: a panel study.

This prospective observational study examined changing trends in mental and behavioral responses, and their association with perceived risk, severity, self-efficacy and isolation status during the Chinese COVID-19 epidemic. There were five waves of interviews. Descriptive statistics and non-parametric test methods were used for data analysis. Participants numbered 150 for the linkable baseline survey and 102 completed all 5 survey waves and were included in the analysis. Mental stress, emotional status and lifestyle manifested a statistically significant downwards trend across the total period of this panel study. The number of reported new confirmed patients perceived high risk and perceived severity were positively associated with mental stress, emotional status and lifestyle. Self-efficacy was negatively associated with each type of mental and behavioral response. The more time people were confined to their home, the more serious the emotional and lifestyle problems. Dose-response relationships were noted between the number of reported new confirmed patients and mental stress, emotional status and lifestyle during the five observation points. This study yielded new information about mental and behavioral responses among Chinese people during the COVID-19 epidemic. Policy changes and health education are essential for minimizing the adverse health effects of these responses.
