The TCQ-SF is a 12-item questionnaire that assesses 4 components of tobacco craving: emotionality (3 items), expectancy (3 items), compulsivity (3 items) and purposefulness (3 items). Responses to each item are scored from 1 (strongly disagree) through 7 (strongly disagree). Component scores are defined as the sum of the scores within each component. The total score is defined as the sum of the 4 component scores. Emotionality scores may range from 3 to 21, with lower scores indicating weaker emotional signs of tobacco craving.

An adverse event (AE) is defined as any untoward medical occurrence in a clinical trial subject administered a medicinal product and which does not necessarily have a causal relationship with the treatment. A serious adverse event (SAE) is defined as an AE that results in any of the following: results in death; is life-threatening; requires hospitalisation or prolongs existing inpatient's hospitalisation; results in persistent or significant disability or incapacity; results in a congenital abnormality or birth defect; is an important medical event which requires medical intervention to prevent any of the above outcomes.TEAEs are defined as AEs not present prior to first administration of investigational product, or AEs present before first administration of investigational product that worsen after the participant receives the first dose of investigational product.
