Illness representations of vaping associated lung injury (VALI) and E-cigarette use: common sense model of self-regulation driven mixed-method approach

Objective The study explored differences in illness representations of VALI guided by the Common-Sense Model of Self-Regulation (CSM-SR) among non-patient adults. Design We employed a cross-sectional concurrent mixed-methods design. In the quantitative analysis, we used multivariate analysis of covariance (MANCOVA). Immersion/crystallization was used to analyze qualitative data. Main outcome measures We measured differences in illness representations of VALI by e-cigarette use status, gender, and urban/rural residence. Results E-cigarette use was associated with illness representations of VALI. Current e-cigarette users discounted the detrimental nature of VALI, compared to former and never e-cigarette users. Gender and urban/rural residence moderated the association between e-cigarette use and illness representation of VALI. In the qualitative analysis, 49.3% respondents reported components of the timeline (e.g. permanent), identity (e.g. shortness of breath), causes (e.g. THC products), consequences (e.g. life-threatening), cure/control (e.g. stop vaping), and worry (e.g. fearful). Conclusion Perceptions about VALI, such as cure and timeline, were associated with e-cigarettes use. Understanding the context in which adults perceive VALI, such as gender and rurality, may contribute to developing interventions that influence e-cigarette cessation. Future research employing CSM-SR to target strategies for promoting vaping abstinence is warranted.

Automated summary

This study explored the differences in illness representations of VALI among non-patient adults guided by the Common-Sense Model of Self-Regulation. The results showed that e-cigarette use was associated with illness representations of VALI, with current users discounting the detrimental nature of VALI compared to former and never users. Gender and urban/rural residence moderated the association as well. Qualitative analysis revealed components of VALI perceptions, such as timeline, identity, causes, consequences, cure/control, and worry. Understanding these perceptions and contexts may contribute to interventions for e-cigarette cessation.
