Examining the bidirectional longitudinal associations between body mass index and episodic memory following bariatric surgery.

Background: The relationship between obesity and episodic memory (i.e., conscious memory for specific events) is hypothesized to be bidirectional.

Examination of the effects of cannabidiol on menstrual-related symptoms.

Some individuals attempt to alleviate menstrual-related symptoms (MRS) by using cannabis and report having expectations that cannabis can improve MRS; however, no study has examined the effect of cannabinoids on MRS. The present study is a pre-post, randomized, open-label trial that aimed to examine the effects of oral cannabidiol (CBD) isolate for alleviating MRS. Participants were assigned randomly to one of two open-label dosing groups of CBD softgels (160 mg twice a day, BID, = 17; 320 mg BID, = 16) and completed a 1-month baseline period.

An exploratory factor analysis of an e-CHUG drinking motives scale with mandated students.

Objective: Colleges maintain alcohol policies in response to student alcohol misuse, and sanctions for violating these policies often mandate students to attend alcohol education and/or counseling (Anderson & Gadaleto, 2021). Electronic Checkup to Go (e-CHUG) is a widely used online motivational intervention program that provides feedback to college students to encourage them to alter their drinking behaviors (eCheckup to Go, 2021). While measures included in e-CHUG have clear clinical utility, their psychometric properties have not been evaluated.

A Double-Blind, Randomized, Placebo-Controlled Test of the Effects of Cannabidiol on Experiences of Test Anxiety Among College Students.

Oral administration of cannabidiol (CBD) has shown to yield a variety of therapeutic benefits among humans, particularly regarding symptoms of anxiety. This study tested single oral administration doses of CBD (150, 300, or 600 mg), compared to placebo, for reducing test anxiety (TA) in a researcher-derived experimental analog. Our sample included 32 healthy college students who self-reported moderate-to-severe levels of TA.

An investigation of the reinforcing value of video game playing relative to concurrently available monetary alternatives.

Objective: Video game playing (VGP) has received recent attention as a result of sharing many similarities with other addictive behaviors. Behavioral economic models are commonly used to understand drug use and other addictive behaviors and may similarly inform conceptual models of VGP.

Method: The present study employed behavioral economic principles to conceptualize relative reinforcing value for playing video games compared to concurrently available alternative potential monetary reinforcers.

The Effects of Alcohol Priming on the Subsequent Value of Alcohol.

Objective: Previous research has investigated the effects of substance priming (i.e., substance exposure or preload) on the subsequent value of alcohol.
