title: Development and initial validation of the White Bear Suppression Inventory (Smoking Version).
abstract: BACKGROUND
  Thought suppression can produce a paradoxical rebound in unwanted cognition. Although interest in the role of suppression in nicotine dependence is growing quickly, a validated measure specifically assessing suppression of smoking-related thoughts does not exist. The present study describes the development of the White Bear Suppression Inventory-Smoking Version (WBSI-S).
  
  
  METHODS
  The WBSI-S, in vivo monitoring of avoidance, and several other measures were completed as a part of a larger study on smoking cessation. Participants (N = 172) completed measures either during (n = 83) or preceding a smoking cessation attempt.
  
  
  RESULTS
  Factor analysis revealed a two-factor structure for the WBSI-S, which was consistent across experimental groups. Both the Intrusive Smoking-related Thoughts and Thought Suppression subscales showed strong internal consistency. The Suppression subscale showed good convergent and discriminant validity; the Intrusion subscale demonstrated equivocal discrimination from other constructs. Participants completing the measure during a quit attempt reported higher self-reported suppression of thoughts about smoking than did continuing smokers.
  
  
  CONCLUSIONS
  Overall, results support the construct validity of the suppression subscale and emphasize the importance of assessing suppression independently from intrusion.
