Understanding E-Cigarette and Vape Use Through the Theory of Planned Behavior: A Science Mapping and TCCM Framework Analysis of Current and Emerging Trends

Four themes were identified: (1) Fundamental role of TPB in predicting e-cigarette intention and actual behavior, (2) Determinants and theoretical approaches to vaping behavior, (3) Vaping among youth, and (4) Communication of e-cigarette use. The findings highlight the central role of TPB in explaining the psychological drivers behind e-cigarette use. Future work would benefit from the identified themes by integrating comprehensive intervention, expanding the theoretical framework, and targeting specific populations to enhance e-cigarette prevention and cessation strategies.
