Cigarette demand and delayed reward discounting in nicotine-dependent individuals with XXXX and controls: an initial study.

@entity1 @entity161 @entity914 @entity146
RATIONALE: The high prevalence of smoking and low cessation rates among individuals with @entity161 and similar conditions are not well understood. Behavioral economics has been extensively applied to studying @entity146 and may contribute to understanding smoking in this subpopulation. OBJECTIVES: This study compared smokers with @entity914 ( @entity914 ) and control smokers (CS) on indices of cigarette demand and delayed reward discounting, a behavioral economic index of impulsivity. MATERIALS AND METHODS: The @entity914 (n=25) and CS (n=24) groups participated in two sessions approximately 1 week apart. During the first session, delay discounting was assessed using the Monetary Choice Questionnaire. During the second session, @entity1 smoked their usual brand ad libitum through a smoking topography assessment device, after which cigarette demand was assessed using a cigarette purchase task. Primary comparisons were of the hyperbolic discounting function, k, and indices of cigarette demand. RESULTS: Compared to the CS group, the @entity914 group exhibited significantly higher intensity of demand, and significantly greater consumption and expenditure across the inelastic portion of the demand curve, but no differences were evident on the other demand indices. No differences were evident for delay discounting. The @entity914 group also exhibited heavier smoking topography and two indices of smoking topography were significantly correlated with demand. CONCLUSIONS: These results provide further evidence of higher incentive value of cigarettes among @entity914 individuals, but not greater impulsivity, as measured by discounting. Considerations include potentially important methodological factors and the role of satiation/withdrawal.
