Brief Questionnaire of Smoking Urges (BQSU)
WEST
To assess tobacco smoking craving and to verify protocol compliance, participants completed the BQSU (10 items) at the neuroimaging session (West & Ussher, 2009). Items are rated on a 7-point scale, with 1 indicating ‘strongly disagree’ and 7 indicating ‘strongly agree’. Items are summed to generate a score for each subscale and a total score. The total score (10 items, α = .96) was calculated for each participant. Higher scores indicate greater smoking urges/craving.
