Findings that were significant at p < .001 are reported in the manuscript to account for familywise error and are bolded in the current table. However, findings that were significant at p < .05 and p < .01 are noted in the table because future research may be conducted using this measure to address more targeted research questions. Data are presented as Mean (standard deviation). Sex (female/male), Smoking Status (current smoking no/yes), Successful Quit Smoking Attempt Using E-cigarettes (no [< 1 month]/yes [≧ 1 month]), Past-Month Vaping (no/yes), Daily Vaping (no/yes), and Nicotine E-liquid Use (no/yes).
