Introduction: Using the self-regulatory executive function model as a basis, this study explored whether, among substance users, metacognitive beliefs and repetitive negative thinking were associated with impulsiveness.
Methods: A total of 100 substance users were recruited. Impulsiveness, metacognitive beliefs, rumination and worry were assessed. Correlation and hierarchal regression analyses were run.
Results: Beliefs about the need to control thoughts, lower cognitive self-consciousness and brooding rumination were found to be independent predictors of the total score on impulsiveness in the hierarchical regression analysis. Further regression analyses indicated that motor impulsiveness was predicted by a combination of beliefs about the need to control thoughts and brooding rumination, while non-planning impulsiveness was predicted by beliefs about the need to control thoughts and lower cognitive self-consciousness.
Conclusion: Among substance users, higher impulsiveness is associated with the tendency to endorse beliefs about the need to control thoughts and brooding rumination. Among substance users, beliefs about the need to control thoughts and brooding rumination (and potentially cognitive self-consciousness) could be a suitable therapeutic targets to mitigate particularly motor impulsiveness and non-planning impulsiveness.

Since automobiles are the primary means of transportation in modern society, the assessment of health effects from acute and chronic exposure to pollutants in automobiles is crucial. In this study, the concentration of volatile organic compounds (VOCs), carbonyl compounds, and odor-including substances in newly manufactured automobiles were analyzed, and exposure factors reflecting automobile user characteristics were selected for health risk assessment. Toluene exhibited the highest concentration (203.

The legalization of recreational cannabis use has expanded the availability of this psychoactive substance in the United States. Research has shown that chronic cannabis use is associated with altered working memory function, however, the brain areas and neural dynamics underlying these affects remain poorly understood. In this study, we leveraged magnetoencephalography (MEG) to investigate neurophysiological activity in 45 participants (22 heavy cannabis users) during a numerical WM task, whereby participants were asked to either maintain or manipulate (i.

Background: Simultaneous alcohol and marijuana use (SAM) and food restriction on days students intend to drink are associated with an increased risk of substance use-related consequences. However, these negative outcomes have been studied mostly in alcohol-only use contexts. Little is known about the combination of alcohol, marijuana, SAM, and food restriction.

Objective: To study the heterogeneity and influencing factors of self-acceptance of drug addicts in compulsory isolation in 2 drug rehabilitation centers in Sichuan Province, and to analyze the effects of different types of self-acceptance on subthreshold depression in drug addicts, in order to provide useful references for improving their mental health.
Methods: Self-acceptance Questionnaire (SAQ), Drug use Stereotype Threat Scale(DSTS) and Center for Epidemiologic Studies Depression Scale(CES-D) were used to conduct a questionnaire survey in January 2024 on 1068 drug addicts in two compulsory isolation drug rehabilitation centers in Sichuan Province.
Results: Drug addicts self-acceptance can be categorized into 5 potential categories; men were more likely than women to show lower self-acceptance in the 'low-low'(β = 0.
