Assessing Perceptions and Behaviors Related to Vaping Nicotine: The Nicotine Addiction Perceptions Scale.

Background: Existent research examining perceptions of nicotine addiction use largely surface level items that fail to address the complexity of nicotine addiction. Additional investigation is needed to better understand people's perceptions of nicotine addiction and whether these align with measures of nicotine dependence. Understanding these perceptions about nicotine addiction may help provide insight into vaping intentions and behavior. This study examines the validity of the Nicotine Addiction Perceptions (NAP) scale, a novel measure designed to assess perceptions of addictive vaping behavior that aligns with the clinical dimensions of tobacco use disorder.

Methods: Data were collected from U.S. adults via Prolific (n = 549). As part of scale development and validation a confirmatory factor analysis and psychometric evaluation was conducted. The NAP's reliability, convergent, discriminant, and criterion validity were established.

Results: A five-factor solution returned acceptable fit on all model indices (RMSEA = 0.050; CFI = 0.994; TLI = 0.993). The NAP was significantly related to assessments of perceived risk, 6 month quit intentions, the number of quit intentions over the past year, and past 30-day e-cigarette use (P's < .05). Findings also indicate support for discriminant validity.

Conclusions: Findings suggest that for most, perceptions of nicotine addiction may not fully align with the clinical criteria of addiction, which may be due to the lack of education surrounding the clinical definition. Future research examining perceptions of nicotine addiction can utilize the NAP scale to better understand people's understanding of addiction and its relationship to vaping-related behavior.
