Self-control as measured by delay discounting is greater among successful weight losers than controls.

Long-term weight loss maintenance is likely to require strong self-control in order to sustain changes in behavior patterns. We, therefore, tested the hypothesis that those who have successfully maintained weight loss may have superior self-control compared to control participants. Self-control was assessed using a delay discounting task through a webbased assessment of members of the National Weight Control Registry (NWCR: N = 757; non-obese = 605; obese = 152) and control participants (Control N = 443; nonobese = 236; obese = 207) from Amazon's Mechanical Turk.

To drink or to drink less? Distinguishing between effects of implementation intentions on decisions to drink and how much to drink in treatment-seeking individuals with alcohol use disorder.

Introduction: For many people with alcohol use disorders, alcohol drinking is a highly ingrained and automatized behavior with negative long-term health consequences. Implementation intentions, a behavioral intervention that links high-risk drinking situations with alternative, healthier responses, provide a means to intervene on habitual drinking behaviors. Here, a pilot treatment using implementation intentions was assessed with remote assessments and treatment prompts.

Cross-commodity delay discounting of alcohol and money in alcohol users.

Despite real-world implications, the pattern of delay discounting in alcohol users when the commodities now and later differ has not been well characterized. In this study, 60 participants on Amazon's Mechanical Turk completed the Alcohol Use Disorder Identification Test (AUDIT) to assess severity of use and completed four delay discounting tasks between hypothetical, equivalent amounts of alcohol and money available at five delays. The tasks included two cross-commodity (alcohol now-money later and money now-alcohol later) and two same-commodity (money now-money later and alcohol now-alcohol later) conditions.

Toward a laboratory model for psychotherapeutic treatment screening: Implementation intentions and incentives for abstinence in an analog of smoking relapse.

Despite reductions in cigarette smoking in the United States, approximately 40 million Americans are smokers. Innovative interventions are needed to help remaining smokers quit. To develop innovative interventions, precise and effective tools are needed.

Neurocognitive dysfunction in addiction: Testing hypotheses of diffuse versus selective phenotypic dysfunction with a classification-based approach.

Neurocognitive dysfunctions are frequently identified in the addictions. These dysfunctions may indicate either diffuse dysfunction or may represent separate facets that have differential importance to the addiction phenotype. In a sample (n = 260) of alcohol and/or stimulant users and controls we measured responses across 7 diverse neurocognitive measures.
