Predictors of delay discounting among smokers: education level and a Utility Measure of Cigarette Reinforcement Efficacy are better predictors than demographics, smoking characteristics, executive functioning, impulsivity, or time perception.

摘要: Ninety-four smokers completed the delay discounting procedure for either hypothetical amounts of money, $10 (money) and $1000 or cigarettes ($10 worth cigarettes). We investigated how variables previously found to be related rates accounted observed results. These included following: demographic information, smoking characteristics, executive function abilities, impulsivity, time perception, Utility Measure Cigarette Reinforcing Efficacy (UMCE). Education level UMCE were each significantly correlated with 3 out 4 measures. Moreover, largest effect sizes between these two measures four All potential predictors also using step-wise linear regression Bayesian Information Criterion (BIC) analysis — BIC models revealed that education large portions variance. conclude most consistent discounting.
