“…higher TCI grade was significantly associated with failure of quitting smoking after adjusting for gender, age, FTND, CES-D, type of prescription, motivation for quitting smoking, self-efficacy for quitting smoking and having a present illness. The present results together with our previous findings [11] demonstrated that TCI grading is an independent predictor for success of quitting smoking in smoking cessation settings. Therefore, we think that the TCI is a useful indicator for monitoring the efficacy of success of quitting smoking during smoking cessation treatment.…”

“…We previously examined how closely TCI grade is associated with success of quitting smoking among 85 individuals who received Japanese SCT compared with the QSU-brief (there was no overlap of participants in the previous study and the present study) [11]. The results suggested that the TCI, as well as QSU-brief, can be used as a predictive tool for success of quitting smoking.…”

“…We previously developed a new craving index named the Tobacco Craving Index (TCI) which consists of two axes: the strength and frequency of craving [11]. Although the TCI consists of only two axes, it showed almost the same sensitivity and specificity in predicting the success of quitting smoking as the brief form of the Questionnaire of Smoking Urges (QSUbrief) in a Japanese smoking cessation therapy (SCT) setting in a limited sample size of 85 smokers [11]. Development of an easy-to-use and reliable indicator of craving is important in clinical settings.…”

Background We previously developed the Tobacco Craving Index (TCI) to assess craving of smokers. In the present study, we validated the relationship between the TCI grade over the 5 sessions of Japanese smoking cessation therapy (SCT) and success of quitting smoking among 889 Japanese patients. Methods The Japanese SCT consists of 5 sessions of SCT (first session and sessions 2, 4, 8 and 12 weeks later). In the TCI questionnaire, patients are asked to rate their strength of craving and frequency of craving, each on a four-point Likert scale. Patients are classified into one of four grades based on their responses (0, I, II, III, with III indicating severe craving). The TCI questionnaire was administered to each participant at each session of the SCT. This study included participants of Japanese SCT who answered the TCI at the first session of the SCT at five Japanese smoking cessation clinics. Patients who dropped out of the SCT from the second to the fifth sessions were considered to have failed smoking cessation. To elucidate how much the TCI grade predicts smoking status at the last session, we performed multivariate logistic regression analysis with adjustment for confounding factors. Results Participants who had higher TCI grade(III) in the 2nd through 5th sessions showed significantly lower probability for success of quitting smoking than those who had lower TCI grades(0 or I) (adjusted odds ratio: 2nd session: 0.30, 3rd session: 0.15, 4th session: 0.06, 5th session: 0.02). Conclusions We validated the usefulness of the TCI grade for assessing probability of quitting smoking by using a large number of smoking cessation settings.

“…We aimed to recruit 84 participants, which would provide 90% power at an alpha level of .005 to detect an effect size of Cohen's d = 0.92, and 80% power at an alpha level of smoking cessation intervention consistently reported QSU-Brief scores that were ~10 points lower than those who failed to quit smoking (32).…”

Several countries have implemented policies restricting flavoured e-cigarette products, although the impact on smokers is unclear. Here, smokers randomised to use an e-cigarette with flavoured (fruit/sweet) or unflavoured nicotine-containing e-liquids for one week did not differ in cigarette craving, experiences of using e-cigarettes, or smoking cessation intentions/motivations. Further research is needed to establish if differences emerge over longer periods of exposure, and whether there is any effect on smoking cessation. These findings suggest that, during an initial switch from smoking to using e-cigarettes, there may be little impact of using unflavoured e-liquids on cigarette craving if fruit/sweet-flavoured e-liquids are restricted.

BackgroundE-liquid flavour restrictions may discourage electronic cigarette (e-cigarette) uptake among youth. However, possible unintended consequences may include reduced appeal and effectiveness of e-cigarettes for smoking cessation. Non-tobacco flavours appear to be important for smoking cessation, but how and why are currently unclear.MethodsWe conducted an experimental study in a UK sample of adult daily smokers using an independent groups design (N=84). Participants were randomised to use an e-cigarette with nicotine-containing fruit/sweet-flavoured e-liquid (blackcurrant, strawberry, vanilla, caramel) or unflavoured e-liquid for 1 week. The primary outcomes were average, peak and cue-elicited cigarette craving (the latter was assessed using a cue exposure task). The secondary outcomes were smoking lapse occurrence, enjoyment of the e-cigarette, ease of transitioning from smoking to using an e-cigarette, intentions to continue using an e-cigarette, intentions and motivation to quit smoking, return to smoking, and continuation of e-cigarette use.ResultsE-liquid flavouring did not appear to have an effect on average cigarette craving (b 0.18, 95% CI −0.44 to 0.79, p=0.57), peak cigarette craving (b −0.12, 95% CI −0.59 to 0.35, p=0.62) or cue-elicited cigarette craving (b −0.21, 95% CI −3.86 to 3.43, p=0.91). We did not find evidence of a difference in secondary outcomes.ConclusionsWe did not find evidence to suggest that nicotine-containing fruit/sweet-flavoured and unflavoured e-liquids have different effects on cigarette cravings after 1 week of use. Further research is needed to establish if differences emerge over longer periods of exposure and extend to smoking cessation outcomes.
