title: Evaluation of the brief questionnaire of smoking urges in Black light smokers.
abstract: BACKGROUND
  This study evaluated the factor structure of the Brief Questionnaire of Smoking Urges (QSU-Brief) within a sample of Black light smokers (1-10 cigarettes per day).
  
  
  METHODS
  The QSU-Brief was administered to 540 (mean age = 46.5; 66.1% women) urban Black light smokers upon entering a smoking cessation clinical trial. An exploratory factor analysis (EFA) was conducted to evaluate the factor structure of this 10-item measure.
  
  
  RESULTS
  An EFA indicated that as in other samples, the construct of craving in a Black sample is defined by 2 factors; 1 factor emphasizing the positive reinforcement of smoking and the other factor emphasizing the negative reinforcement properties of smoking.
  
  
  CONCLUSIONS
  Findings largely replicate a 2-factor structure of craving seen in smokers from other racial/ethnic groups, demonstrating the clinical utility of the QSU-Brief in measuring craving in Black light smokers.
