Group differences in binge eating, impulsivity, and intuitive and mindful eating among intermittent fasters and non-fasters.

Intermittent fasting (IF) is an increasingly popular diet involving short-term fasting and/or caloric restriction. While published research highlights physiological effects (e.g.

Pain and alcohol consumption in virtual reality.

Research suggests situational pain may motivate alcohol consumption, suggesting that pain may be an antecedent for problematic drinking behavior. In this pilot project, we assessed the effect of a painful thermal stimulus on drinking topography in a virtual reality bar environment using real alcohol-containing beverages. We also examined psychosocial factors that may account for individual differences in pain as an antecedent for alcohol use.

Analgesic effects of alcohol in adults with chronic jaw pain.

Background: Although recent literature provides promising support for the analgesic properties of alcohol, potential differences in alcohol analgesia as a function of chronic pain status are not well understood. Thus, this study examined chronic pain status as a potential moderator of alcohol analgesia and distinguished between multiple aspects of pain experience and sensitivity: pain threshold, pain intensity, pain unpleasantness, and perceived relief.

Methods: Social drinkers with (N = 19) and without (N = 29) chronic jaw pain completed two testing sessions in a counterbalanced order: alcohol (target BrAC = 0.

A virtual reality platform for the measurement of drinking topography.

Background: The assessment of alcohol consumption during a drinking bout, known as drinking topography, may help improve understanding of biopsychosocial mechanisms underlying alcohol consumption. However, past studies have been limited by effort-intensive, time-consuming, and error-prone processes involved in collecting, organizing, and standardizing drinking topography data. Recent technologies allowing integrated data collection and greater environmental control, such as virtual reality (VR), could resolve these problems.

Sex differences in associations between delay discounting and expectancies for alcohol analgesia.

Self-medication of pain with alcohol is prevalent, and expectancies for alcohol analgesia likely influence pain relief and alcohol consumption. Hazardous alcohol use has been associated with greater delay discounting rates; however, little is known about the relationship between delay discounting and expectancies for alcohol analgesia. Therefore, the present study examined sex differences in associations between delay discounting and expectancies for alcohol analgesia.

Acute Tolerance to the Analgesic Effects of Alcohol.

Objective: The goal of this study was to determine whether the acute analgesic effects of alcohol intake are moderated by acute alcohol tolerance, characterized by differing subjective and neurobehavioral effects of a given blood alcohol concentration (BAC) depending on whether BAC is rising or falling.

Method: Twenty-nine healthy drinkers (20 women) completed two laboratory sessions in which they consumed a study beverage: active alcohol (target BAC= .08 g/dl) and placebo.

Sex moderates the effects of experimentally induced musculoskeletal pain on alcohol demand in healthy drinkers.

Background: Pain may serve as an antecedent for alcohol use, increasing risk for hazardous drinking and associated consequences. Delayed onset muscle soreness (DOMS) induction produces clinically relevant but time-limited musculoskeletal pain. This study was conducted to determine whether DOMS induction on the dominant elbow flexors influenced alcohol demand using the Alcohol Purchase Task (APT).
