Cross-cultural examination of college marijuana culture in five countries: Measurement invariance of the Perceived Importance of Marijuana to the College Experience Scale.

Addict Behav 2019 Apr 4;96:11-17. Epub 2019 Apr 4.

Center on Alcoholism, Substance Abuse, and Addictions, University of New Mexico, United States of America.

Marijuana internalized norms, measured by the Perceived Importance of Marijuana to the College Experience Scale (PIMCES; 8 items), has been found to be distinct from marijuana descriptive/injunctive norms and to be a unique robust predictor of marijuana-related outcomes among college students, yet the role of these beliefs has not been studied outside the U.S. Using confirmatory factor analysis, the present work examined the level of measurement invariance (i.

Psychiatric comorbidity among first-time and repeat DUI offenders.

Addict Behav 2019 Apr 1;96:1-10. Epub 2019 Apr 1.

Division on Addiction, Cambridge Health Alliance, United States of America; Harvard Medical School, United States of America.

Driving under the influence of alcohol or other substances is a serious public health concern. Previous research has shown that psychiatric comorbidity is more prevalent for repeat offenders than the general population, and that first-time offenders exhibit elevated rates of psychiatric comorbidity, but few studies have directly compared first-time and repeat DUI offenders. The current study compares psychiatric comorbidity among repeat and first-time DUI offenders. Read More

Addict Behav 2019 Mar 7;95:91-97. Epub 2019 Mar 7.

Department of Psychology, California State University San Marcos, United States of America.

Recent data regarding growth in concurrent use of nicotine and marijuana have raised concern that reductions in legal restrictions on marijuana use may increase risk for tobacco-related harms. Previous studies have shown cross-sectional links between use of both substances, but less is known about associations over time. The goal of the present study was to test the hypothesis that there is a bidirectional relationship between use of marijuana and use of tobacco products over time, such that increasing use of either substance would predict increasing use of the other.

Department of Community Health and Health Behavior, School of Public Health and Health Professions, University at Buffalo, 3435 Main Street, Buffalo, NY 14214, United States.

Several theories posit that cannabis and other substances are used to reduce negative affect. This daily report study considered whether variations in positive and negative affect, reported each morning, contributed to the likelihood of cannabis use later that day. We also explored whether levels of positive and negative affect reported immediately after cannabis use improved, relative to that day's morning levels. Read More

School of Psychology, Liaoning Normal University, Da Lian, China.

The results of some neuroimaging studies have revealed that people with internet addiction (IA) exhibit structural and functional changes in specific brain areas and connections. However, the understanding about global topological organization of IA may also require a more integrative and holistic view of brain function. In the present study, we used synchronization likelihood combined with graph theory analysis to investigate the functional connectivity (FC) and topological differences between 25 participants with IA and 27 healthy controls (HCs) based on their spontaneous EEG activities in the eye-closed resting state.

Mediation analysis with zero-inflated substance use outcomes: Challenges and recommendations.

Addict Behav 2019 Feb 18. Epub 2019 Feb 18.

Arizona State University, Tempe, AZ, United States.

Mediating mechanisms are important components of substance use research, as many substance use interventions work by targeting mediating variables. One issue that is common in substance use research is the presence of many responses of zero in a count variable that is the primary outcome of interest, such as number of drinks per week or number of substances used in the past month. The goal of this paper is to highlight the unique challenges that substance use researchers face when conducting mediation analysis with a zero-inflated count outcome. Read More

Department of Psychology, Università degli Studi della Campania "Luigi Vanvitelli", Viale Ellittico, 31, 81100 Caserta, Italy. Electronic address:

Chasing is a central feature of gambling disorder and refers to the attempt by individuals to recover financial losses by continuing to gamble. Although several efforts have been made to individuate the factors involved in the complex phenomenon of chasing, little is known regarding its association with delay discounting and craving, both considered important in the development and maintenance of gambling disorder. In the present study, the interplay between chasing, delay discounting, and craving (while controlling for gambling severity) was investigated. Read More

Dopaminergic and clinical correlates of high-frequency repetitive transcranial magnetic stimulation in gambling addiction: a SPECT case study.

Addict Behav 2019 Feb 14;93:246-249. Epub 2019 Feb 14.

Department of Neuroscience, Imaging and Clinical Sciences, "G. d'Annunzio" University, Chieti, Italy.

Repetitive Transcranial Magnetic Stimulation (rTMS) shows the potential to modulate local brain activity, thus resulting in a modulatory action on neurocircuitries implicated in the pathophysiology of Gambling Disorder (GD). We report the case of a GD patient treated with two weeks of high frequency (15 Hz) rTMS over the dorsolateral prefrontal cortex (DLPFC). At baseline and after rTMS treatment the patient underwent a SPECT examination with (123)I-FP-CIT tracer, to test changes in dopamine transporter (DAT) availability. Read More

Department of Psychiatry and Behavioral Sciences, University of Washington, 1959 NE Pacific St., Box 356560, Seattle, WA 98195-6560, USA.

This paper provides a tutorial companion for the methodological approach implemented in Huh et al. (2015) that overcame two major challenges for individual participant data (IPD) meta-analysis. Specifically, we show how to validly combine data from heterogeneous studies with varying numbers of treatment arms, and how to analyze highly-skewed count outcomes with many zeroes (e. Read More

The role of energy drink consumption in the intention to initiate marijuana use among adolescents.

Addict Behav 2019 Feb 10;93:240-245. Epub 2019 Feb 10.

Department of Criminal Justice, The University of Texas at San Antonio, 501 W. Cesar E. Chavez Blvd., San Antonio, TX, 78207, United States. Electronic address:

Aims: The current study aims to examine whether energy drink consumption is associated with intentions to try marijuana among adolescents who have never tried marijuana, and whether the effects of energy drink consumption on the intention to try marijuana vary between adolescents who have previously tried alcohol or cigarettes and those who have not.

Methods: This study employs a pooled cross-sectional design and uses a nationally representative sample of 8th (ages 13-14) and 10th (ages 15-16) grade adolescents from seven recent cohorts (2010-2016) of the Monitoring the Future (MTF) study. Logistic regression was employed to examine the association between energy drink consumption (none, light, moderate, heavy) and the odds of intending to initiate marijuana use in the next 12 months, controlling for sociodemographic factors and other health and social behaviors.
