Delayed reward discounting and addictive behavior: a meta-analysis
- J. MacKillop, M. Amlung, L. Few, L. Ray, L. Sweet, M. Munafo
- 4 March 2011
These results provide strong evidence of greater DRD in individuals exhibiting addictive behavior in general and particularly in individuals who meet criteria for an addictive disorder.
Relative reinforcing efficacy of alcohol among college student drinkers.
Initial support for the validity of the RRE indices generated with the alcohol purchase task is provided and programs that attempt to reduce alcohol abuse by eliminating low-cost access to alcohol are supported.
Examination of the Section III DSM-5 diagnostic system for personality disorders in an outpatient clinical sample.
Overall, these results support the general validity of several of the components of this new PD diagnostic system and point to areas that may require further modification.
Further Psychometric Validation of the Mindful Attention Awareness Scale (MAAS)
Mindfulness is an increasingly prominent construct in health research but its study has been impeded by a lack of well-validated measures. The Mindful Attention and Awareness Scale (MAAS; Brown and…

Individual differences in alcohol demand and delayed reward discounting and craving were examined in 61 heavy drinkers to emphasize the relevance of behavioral economic indices of motivation to AUDs and the potential importance of craving for alcohol in this relationship.

Findings support the validity of a CPT as a time- and cost-efficient method for assessing nicotine reinforcement as well as a heterogeneous pattern of interrelationships among the indices of reinforcement.
Examining impulsivity as an endophenotype using a behavioral approach: a DRD2 TaqI A and DRD4 48-bp VNTR association study

These findings suggest a meaningful interaction between the DRD2 TaqI A and DRD4 VNTR polymorphisms in the expression of impulsivity and provide initial support for the utility of using behavioral measures for clarifying genetic influences on impulsivity.
The latent structure of impulsivity: impulsive choice, impulsive action, and impulsive personality traits

These findings support the hypothesis that diverse measures of impulsivity can broadly be organized into three categories that are largely distinct from one another and warrant investigation among individuals with clinical levels of addictive behavior.
Living in the here and now: interrelationships between impulsivity, mindfulness, and alcohol misuse
The associations between mindfulness and alcohol misuse were entirely a function of impulsivity, and acting on impulses while experiencing a negative affect was significantly associated with level of alcohol consumption andlevel of alcohol-related risk.

A genetic study identifies hundreds of loci associated with risk tolerance and risky behaviors, finds evidence of substantial shared genetic influences across these phenotypes, and implicates genes involved in neurotransmission.
