Background and aimsImpulsivity is a risk factor for addictive behaviors. The UPPS-P impulsivity model has been associated with substance addiction and gambling disorder, but its role in other non-substance addiction-related behaviors is less understood. We sought to examine associations between UPPS-P impulsivity traits and indicators of multiple substance and non-substance addiction-related behaviors in youth with varying involvement in these behaviors.MethodsParticipants (N = 109, aged 16–26 years, 69% males) were selected from a national survey based on their level of externalizing problems to achieve a broad distribution of involvement in addiction-related behaviors. Participants completed the UPPS-P Questionnaire and standardized questionnaires assessing problematic use of substances (alcohol, cannabis, and other drugs) and non-substances (Internet gaming, pornography, and food). Regression analyses were used to assess associations between impulsivity traits and indicators of addiction-related behaviors.ResultsThe UPPS-P model was positively associated with indicators of all addiction-related behaviors except problematic Internet gaming. In the fully adjusted models, sensation seeking and lack of perseverance were associated with problematic use of alcohol, urgency was associated with problematic use of cannabis, and lack of perseverance was associated with problematic use of other drugs than cannabis. Furthermore, urgency and lack of perseverance were associated with binge eating and lack of perseverance was associated with problematic use of pornography.Discussion and conclusionsWe emphasize the role of trait impulsivity across multiple addiction-related behaviors. Our findings in at-risk youth highlight urgency and lack of perseverance as potential predictors for the development of addictions and as potential preventative therapeutic targets.
The aim of this study is to investigate associations between use of cigarettes, cannabis, and alcohol (CCA) and psychosocial problems among adolescents with different cultural backgrounds living in Nordic countries. Data from six questionnaire-based surveys conducted in Denmark, Norway, and Greenland, with participants from different cultural and religious backgrounds, were compared. A total of 2212 adolescents between 15 and 18 years of age participated in the study. The surveys were carried out nationally and in school settings. All adolescents answered a 12-item questionnaire (YouthMap12) with six questions identifying externalizing behavior problems and six questions identifying internalizing behavior problems, as well as four questions regarding childhood neglect and physical or sexual abuse, and questions about last month use of CCA. Externalizing behavior problems were strongly associated with all types of CCA use, while childhood history of abuse and neglect was associated with cigarette and cannabis use. The associations did not differ by sample. Despite differences between samples in use of CCA, national, cultural, and socioeconomic background, very similar associations were found between psychosocial problems and use of CCA. Our findings highlight the need to pay special attention to adolescents with externalizing behavior problems and experiences of neglect and assault in CCA prevention programs, across different ethnic and socioeconomic backgrounds.

Rationale Identifying the predictors of relapse in detoxified alcohol-dependent patients is crucial for effective surveillance procedures and the optimization of treatment. Physiological measures such as functional MRI activity and heart rate variability have been shown as potential markers of relapse prediction. Objectives Our aim was to assess differential pupillary reactions to alcohol-related cues as an objective physiological candidate predictor of relapse. Methods We examined the relationship between cue-elicited pupillary reactions to alcohol stimuli and luminance-controlled neutral stimuli in 21 detoxified alcohol-dependent patients and subsequent relapse outcome at a 4-month follow-up. Results Differential pupillary dilation to alcohol stimuli as compared to neutral stimuli at 150 to 250 ms after stimulus onset substantially improved the model prediction of relapse outcome (additional 27% of variance) beyond that achieved from five standardized questionnaires on alcohol craving, alcohol use, problematic use severity, depressive tendencies, and duration of abstinence (47% of variance). In contrast, alcohol craving did not improve relapse model prediction. Conclusions This pilot study shows that alcohol-dependent patients with greater pupillary dilation to alcohol stimuli are more vulnerable to relapse, and that pupillometry presents as an important tool for addiction science.
Aims: The literature on associations between internalising problems and subsequent alcohol/drug use and problems shows mixed results, and it is important to consider different aspects of internalising problems along with co-occurring externalising problems. Methods: In a longitudinal
