Trait urgency and substance use decision making in adolescents and young adults: The role of socio-affective factors

The personality trait of urgency has been linked to substance use outcomes. This study examined possible mechanisms underlying this relationship. A total of 187 participants divided into two age groups (adolescents aged 15–17 and young adults aged 18–21) completed measures of urgency and affective associations about substance use. They were then asked to read a hypothetical situation in which a protagonist considers using a ‘legal high’, and to report their perceived peer approval and perceived positive and negative consequences of such substance use, as well as the likelihood that they would personally use the substance. Multiple-group path analysis was employed to test a model by which urgency influenced the substance use decision via affective associations and perceived peer approval. In adolescents, urgency was significantly related to positive affective associations, and a significant indirect path from urgency to decision via affective associations was found. In young adults, there was a significant path from urgency to decision via peer approval. Results indicate that high urgency individuals may rely on socio-affective information when considering whether to engage in substance use.     

Substance use disinhibition associated with economically rational decisions to quit a boring task

Preferences for smaller immediate rewards over larger delayed rewards have been associated with a range of negative outcomes, including substance use problems. The present research investigated a potential association between substance use disinhibition and preferences for an immediate reward in a situation where the delayed reward was not the largest. Participants recruited from Amazon Mechanical Turk were required to perform a boring, repetitive task for 25 min in order to earn a $3 bonus. Alternatively, they could quit at any time to receive half the bonus. However, when one fourth the task remained, participants were offered the choice between (a) quitting the boring task for a $3 bonus, and (b) continuing the boring task for a $3 bonus. Participants who chose the economically superior option of quitting the task scored higher on a measure of substance use disinhibition and on the Disinhibition facet of Zuckerman’s Sensation Seeking Scale.     

Is cleanliness next to abstinence? The effect of cleanliness priming on attitudes towards harm reduction strategies for people with substance use disorders

Can exposure to a cleanliness prime affect moral judgements towards harm reduction strategies (HRS) for individuals with substance use disorders? Our research examined (a) the effect of a cleanliness prime on attitudes towards HRS and (b) whether this effect would be attenuated by a brief educational presentation. Participants were randomly assigned to a priming condition and an educational presentation condition. Results demonstrated that (a) the cleanliness prime did not shift attitudes towards HRS, however, (b) the educational presentations significantly shifted attitudes to be more positive after the Harm Reduction presentation and more negative after the Healthy Living presentation. The literature on priming is mixed and our results support a growing body of research challenging the robustness of cleanliness priming and also demonstrates that brief presentations can change attitudes. Our research has implications for education on the benefits of HRS in reducing disease transmission, refuse in the community, and overdose deaths.     

Measuring associations between social anxiety and use of different types of social media using the Swedish Social Anxiety Scale for Social Media Users: A psychometric evaluation and cross-sectional study

Research on the association between social anxiety and social media usage remains inconclusive: despite the preference for computer-mediated communication there is currently no clear empirical support for social anxiety being associated with longer duration of social media use. Self-report measures for social anxiety that are adapted for the context of social media could facilitate further research. The current study aimed to develop a Swedish version of the recently developed Social Anxiety Scale for Social Media Users (SAS-SMU), evaluate its psychometric properties, and explore associations between different uses of social media and social anxiety. Three factors were retained for SAS-SMU with excellent internal consistency. SAS-SMU evidenced convergent validity with measures of social anxiety, negative convergent validity with satisfaction with life, and divergent validity with measures of obsessive-compulsive disorder, depression and generalized anxiety disorder. Results indicated that higher levels of social anxiety were associated with passive and active use as well as longer duration of social media use in general, which is at odds with a previous study where passive use remained the only significant predictor for social anxiety.     

The Network Constellation of Personality and Substance Use: Evolution from Early to Late Adolescence

There is a well-established link between substance use and four personality traits of anxiety–sensitivity, hopelessness, impulsivity, and sensation-seeking. However, construct-level models of personality may conceal indicator-level personality–outcome associations. The current study aims to investigate evolution of the network constellation of personality and cannabis/alcohol use from early to late adolescence. Data comes from the longitudinal Co-Venture cohort (N = 3800). Personality indicators, measured by Substance Use Risk Profile Scale (SURPS) items, and the frequency of cannabis/alcohol use were assessed at four consecutive years (13–17 years old). Network constellations of the SURPS items and cannabis/alcohol use were estimated using Bayesian Gaussian graphical models at four time points. Results highlighted the age-specific associations between personality indicators and substance use. The positive role of the sensation-seeking trait (e.g. attitude towards transgression) was constant, whereas the positive role of hopelessness indicators (e.g. not being enthusiastic about future) and the negative role of anxiety–sensitivity indicators (e.g. fear of having unusual body sensations) were more prominent at early adolescence. The current study provides a novel perspective on the network structure of personality and substance use in adolescence and suggests substance-specific and age-adjusted targets in intervention efforts. © 2020 European Association of Personality Psychology     

问题性网络使用对初中生自杀意念的影响:一个有调节的中介模型

采用戴维斯在线认知量表、自杀意念自评量表、UCLA孤独感量表以及领悟社会支持量表，对江西赣州九所公立学校三个年级的1311名初中生进行测查，探讨问题性网络使用对初中生自杀意念的影响及作用机制。结果发现：（1）问题性网络使用对初中生的孤独感和自杀意念都有显著的正向预测作用；（2）孤独感在问题性网络使用与初中生自杀意念之间起着部分中介作用；（3）孤独感和自杀意念的关系（中介效应的后半段路径）受到领悟社会支持的调节，即孤独感对自杀意念的影响随着领悟社会支持的增强而减弱。因此，问题性网络使用和初中生自杀意念之间存在孤独感的中介作用和领悟社会支持的调节作用。
