Longitudinal impact of impulsivity and sensation-seeking on vaping initiation: The moderating role of peer vaping.
Article in Addictive behaviors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Limited research indicates impulsivity and sensation-seeking are associated with electronic nicotine delivery systems (ENDS) use in young adulthood, however, no study has examined the moderating effect of peer ENDS use on these associations. We examined the impacts of impulsivity and sensation-seeking on ENDS use initiation and determined if peer ENDS use moderates these associations. Participants were 2,590 ENDS naïve (i.e., never used ENDS) young adults involved in multi-wave, 4.5-year longitudinal study (Fall, 2014 - Spring, 2019). At baseline, participants were 18-25 years old (M = 20.1; SD = 1.8), 66.5 % female, 34.2 % non-Hispanic white, 28.1 % Hispanic/Latino, 8.6 % Black, 21.6 % Asian, and 7.4 % identified as another race/ethnicity. Cox's regression models were used to test hypotheses. Predictors were time-varying impulsivity and sensation-seeking, and the moderator was time-varying peer ENDS use. The outcome, ENDS use initiation, was assessed by querying ever ENDS use over 7 follow-up waves. Covariates included socio-demographic characteristics, past 30-day other tobacco use, cannabis use, and binge drinking. Nearly 29% of participants initiated ENDS use during the study period. Sensation-seeking predicted an increased risk of initiating ENDS use (HR = 1.12, 95 %CI:1.03,1.22), but impulsivity did not. Although peer ENDS use directly predicted an increased risk for initiating ENDS use (HR = 1.57, 95 %CI:1.46, 1.68), peer ENDS use did not moderate the associations of impulsivity and sensation-seeking on ENDS use initiation. The role of sensation-seeking on ENDS use initiation is independent of peer use. Prevention programs tailored to those high in sensation-seeking may consider changing attitudes about how desires for novel experiences can be achieved through healthier behaviors.
