Impact of Experimentally Induced Positive and Anxious Mood on Alcohol Expectancy Strength in Internally Motivated Drinkers

The effects of musically‐induced positive and anxious mood on explicit alcohol‐related cognitions (alcohol expectancy strength) in 47 undergraduate students who consume alcohol either to enhance positive mood states (for enhancement motives) or to cope with anxiety (for anxiety‐related coping motives) were investigated. Pre‐ and post‐mood induction, participants completed the emotional reward and emotional relief subscales of the Alcohol Craving Questionnaire – Now. The hypothesis that anxiety‐related coping motivated drinkers in the anxious mood condition (but not those in the positive mood condition) would exhibit increases in strength of explicit emotional relief alcohol expectancies after the mood induction was supported. An additional, unanticipated finding was that enhancement‐motivated drinkers in the anxious condition also showed significant increases in strength of explicit emotional relief (but not emotional reward) alcohol expectancies. The hypothesis that enhancement‐motivated (but not anxiety‐related coping motivated) participants would exhibit increases in explicit emotional reward expectancies following exposure to the positive mood induction procedure was not supported. Taken together with past research findings, the current results highlight the importance of distinguishing between subtypes of negative affect (i.e., anxious and depressed affect) in exploring the affective antecedents of explicit alcohol outcome expectancies.     

驾驶中移动电话的使用：基于自我调整行为的研究视角

因使用移动电话而导致的“驾驶分心”已成为一种严重的道路安全隐患。驾驶者总体上能意识到其危害, 但在驾驶中使用移动电话的现象很普遍。以往研究不能全面地对这一矛盾予以解释, 长期以来更是忽略了对“驾驶分心中自我调整行为”进行研究, 而这一问题能够直接解释驾驶中的移动电话使用行为。从以下三个方面可以对与驾驶分心中自我调整行为有关的研究进行分析和综述：(1)驾驶中移动电话使用行为的一般规律(类型、频率和危险感知等), 驾驶者对移动电话使用行为的理解是诱发自我调整行为的基础; (2)驾驶情境下移动电话使用中可能触发的自我调整行为, 该部分将主要分析自我调整行为的类型及相关属性; (3)如何对移动电话使用行为和自我调整行为进行预测。总体上, 基于对补偿式安全信念进行理解和度量、并以此为切入点对驾驶中移动电话使用及与其有关的自我调整行为展开研究, 这将有助于更好地理解驾驶分心行为。     

压力性生活事件对青少年烟酒使用的影响：基本心理需要和应对方式的链式中介作用

采用压力性生活事件量表、基本心理需要量表、特质应对方式问卷和烟酒使用问卷对867名青少年进行调查,考察了基本心理需要和积极应对方式、消极应对方式在压力性生活事件与烟酒使用关系中的链式中介效应。结果表明：（1）基本心理需要是压力性生活事件与青少年烟酒使用之间的中介变量;（2）积极应对方式、消极应对方式是基本心理需要与青少年烟酒使用之间的中介变量。因此,基本心理需要和积极应对方式、消极应对方式在压力性生活事件与青少年烟酒使用之间起链式中介作用。研究结论对青少年烟酒使用的预防和干预具有重要价值。     

Religiosity and adolescent marijuana use

Among adolescents, religiosity has been associated with lower rates of marijuana use, though few studies have examined its impact on the perceived risk of use. There is strong support that perceived risk of using marijuana is negatively correlated with the frequency of use. We examined the relationship among religiosity, perceived risk, and marijuana use from a national survey of adolescents that contained questions about lifetime, weekly, and past month substance use, social support, religious involvement and attitudes, and perceived riskiness of use. We tested a structural equation model of relationships among latent variables of religiosity and perceived risk, and an observed variable of total days of marijuana use in the past 12 months. Results indicated the model was a good fit to the data and described a mediating relationship of perceived risk of use between religiosity and marijuana use. Implications for leveraging religiosity in prevention of substance use are discussed.     

Who am I? Differential effects of three contemplative mental trainings on emotional word use in self-descriptions

In a large-scale longitudinal mental training study, we examined whether learning different contemplative practices can change the emotional content of people’s self-concept as assessed through emotional word use in the Twenty Statement Test. During three 3-month training modules, participants learned distinct practices targeting attentional, socio-affective, or socio-cognitive capacities, or were re-tested. Emotional word use specifically increased after socio-cognitive training including perspective-taking on self and others, compared to attentional and socio-affective compassion-based trainings, and retest-controls. Overall, our findings demonstrate training-induced behavioral plasticity of the emotional self-concept content in healthy adults and could indicate greater emotional granularity. These findings can inform future interventions in mental health, given that alterations in self-referential processing are a common contributing factor in psychopathology.     

Testing Practices and Attitudes Toward Tests and Testing: An International Survey

On behalf of the International Test Commission and the European Federation of Psychologists' Associations a world-wide survey on the opinions of professional psychologists on testing practices was carried out. The main objective of this study was to collect data for a better understanding of the state of psychological testing worldwide. These data could guide the actions and measures taken by ITC, EFPA, and other stakeholders. A questionnaire was administered to 20,467 professional psychologists from 29 countries. Five scales were constructed relating to: concern over incorrect test use, regulations on tests and testing, internet and computerized testing, appreciation of tests, and knowledge and training relating to test use. Equivalence across countries was evaluated using the alignment method, four scales demonstrated acceptable levels of invariance. Multilevel analysis was used to determine how scores were related to age, gender, and specialization, as well as how scores varied between countries. Although the results show a high appreciation of tests in general, the appreciation of internet and computerized testing is much lower. These scales show low variability over countries, whereas differences between countries on the other reported scales are much greater. This implies the need for some overarching improvements as well as country-specific actions.     

基于“相关线索-自动化用药行为”联结的成瘾记忆消退

成瘾记忆消退致力于消除成瘾者相关线索与药物奖赏效应的联结,以达到消除心理渴求、戒断成瘾行为的目的,但其效果还十分有限。最近,大量的动物和人类实验研究发现:在相关线索下,成瘾者的激活脑区不仅包括中脑边缘皮层-背内侧纹状体,还延伸到感觉运动脑区-背外侧纹状体。这意味着成瘾记忆中存在相关线索与自动化(习惯性)用药行为的联结。所以,与成瘾相关的记忆可能包含两种不同的成分:一是与药物奖赏效应相关的情绪记忆,另一种是与用药动作、技能有关的动作记忆(程序记忆)。由于在成瘾阶段,药物奖赏效应对药物使用和复发的作用已经相对减少,因此,针对成瘾记忆的消退训练,以相关线索与自动化用药行为的联结为标靶,可能可以取得更好的效果,值得做进一步的深入探索。     

青少年网络社交使用频率对网络成瘾的影响:家庭经济地位的调节作用

相关研究表明,由于青少年在网络社交中能够获得他人的认可与支持,网络社交对网络成瘾具有显著的影响。自我价值定向理论认为自我价值是人们行为的终极理由,其中他人的认可与接纳、家庭社会经济地位都是自我价值的重要支撑。当青少年生活在高社会经济地位环境中,其自我价值可能越高,网络社交使用频率对网络成瘾的影响可能会减弱。我们从全国7个省收集了1216份青少年自评的网络社交使用频率、网络成瘾倾向以及父母自评的社会经济地位等指标的数据。结果表明:家庭社会经济地位调节着网络社交使用频率与网络成瘾倾向的关系;进一步的分析表明,在高社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响不显著,而在低社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响极其显著。结果支持了自我价值定向理论。     

Motivational enhancement treatment in outpatient addiction centers: A multisite randomized trial

Background/Objectives: Motivational Enhancement Treatment in Spanish (METS) is a brief intervention aimed at resolving patient ambivalence towards behavior change that has demonstrated efficacy in substance use disorder treatment to reduce use and increase treatment engagement in different populations. In order to have evidence for its implementation in Mexico, a multi-site, randomized, two-arm, controlled clinical trial was conducted at three outpatient addiction treatment centers in the country to compare the effect of METS with Counseling as Usual (CAU). Method: One hundred and twenty patients were randomized to receive three sessions of METS (n = 54) or CAU (n = 66) during the first four weeks of treatment and were assessed during the following 12 weeks. Primary outcome measures were self-reported days of substance use and of treatment services utilization, which were tested using Generalized Estimating Equations. Results: Results associated both conditions with significant changes in substance use over, whereas there were no differences between conditions in substance use or in service utilization. Conclusions: Findings do not support the hypothesis that METS is more effective than CAU, but suggest that brief interventions at treatment initiation may improve patient outcomes.     

Cognitive function of youths born to mothers with opioid and poly-substance abuse problems during pregnancy

Previous research has provided inconclusive evidence regarding the neuropsychological difficulties of children born to mothers partaking in opioid or poly-drug use during pregnancy. Little is known about how these children fare as they get older. The present longitudinal study includes follow-up data on 45 children born to mothers who used heroin and poly-drugs and a group of 48 children without prenatal drug exposure. Most of the drug-exposed youths were placed in permanent foster or adoptive homes before one year of age. The youths (ages 17 to 21) were administered 10 neuropsychological tests. The drug-exposed youths had cognitive and fine motor functions within the normal range compared to population norms but performed significantly worse than the non-exposed group. There were indications of generally lower cognitive functions rather than specific problems with executive functioning. Lower mean birthweight in the risk group (619 grams mean difference, p < .001) only partially mediated the group differences in cognitive functioning. There was a tendency for youths who had few and early changes in their caregivers or who were born to mothers who had used the least number of different drugs during pregnancy to have the best cognitive scores. The study indicates that youths born to mothers who used multiple drugs during pregnancy are vulnerable relative to their peers within a wide range of cognitive functions. The vulnerability seems to be related not only to the mother’s drug use during pregnancy but also to factors such as birthweight and unstable parental care during infancy.
