Multidimensionality in impulsivity and alcohol use: a meta-analysis using the UPPS model of impulsivity

An examination of state and trait urgency in individuals with binge-eating disorder

OBJECTIVE

Negative urgency (i.e., acting rashly when experiencing negative affect; NU), is a theorised maintenance factor in binge-eating type eating disorders. This study examined the association between trait NU and eating disorder severity, momentary changes in state NU surrounding episodes of binge eating, and the momentary mechanistic link between affect, rash action, and binge-eating risk.

METHODS

Participants were 112 individuals with binge-eating disorder (BED). Baseline measures included the UPPS-P Impulsive Behaviour Scale to assess trait NU and the Eating Disorders Examination to assess binge-eating frequency and global eating disorder severity. Ecological momentary assessment captured real-time data on binge eating, negative affect, and state NU.

RESULTS

Multiple regression analysis revealed a strong association between trait NU and eating disorder severity. Generalised estimating equations showed that state NU increased before and decreased after binge-eating episodes, and that this pattern was not moderated by trait-level NU. Finally, a multilevel structural equation model indicated that increases in rash action mediated the momentary relationship between states of high negative affect and episodes of binge eating.

CONCLUSION

These findings underscore the importance of both trait and state NU in binge-eating type eating disorders, and suggest NU as a potential key target for intervention.

Alcohol sipping patterns, personality, and psychopathology in Children: Moderating effects of dorsal anterior cingulate cortex (dACC) activation

BACKGROUND

Alcohol, the most consumed drug in the United States, is associated with various psychological disorders and abnormal personality traits. Despite extensive research on adolescent alcohol consumption, the impact of early alcohol sipping patterns on changes in personality and mental health over time remains unclear. There is also limited information on the latent trajectory of early alcohol sipping, beginning as young as 9-10 years old. The dorsal anterior cingulate cortex (dACC) is crucial for cognitive control and response inhibition. However, the role of the dACC remains unclear in the relationship between early alcohol sipping and mental health outcomes and personality traits over time.

METHODS

Utilizing the large data from the Adolescent Brain Cognitive Development study (N = 11,686, 52% males, 52% white, mean [SD] age 119 [7.5] months, 9807 unique families, 22 sites), we aim to comprehensively examine the longitudinal impact of early alcohol sipping patterns on psychopathological measures and personality traits in adolescents, filling crucial gaps in the literature.

RESULTS

We identified three latent alcohol sipping groups, each demonstrating distinct personality traits and depression score trajectories. Bilateral dACC activation during the stop-signal task moderated the effect of early alcohol sipping on personality and depression over time. Additionally, bidirectional effects were observed between alcohol sipping and personality traits.

CONCLUSIONS

This study provides insights into the impact of early alcohol consumption on adolescent development. The key finding of our analysis is that poor response inhibition at baseline, along with increased alcohol sipping behaviors may accelerate the changes in personality traits and depression scores over time as individuals transition from childhood into adolescence.

Impulsivity, mental health state and emotion regulation modulate alcohol and marijuana use in a sample of Argentinean citizens

Impulsivity and substance-related outcomes share a complex relationship, as various facets of impulsivity exhibit distinct associations with different drug-related outcomes. This study examines the associations between frequency and quantity of alcohol and marijuana use with impulsivity traits, psychological distress, and the utilization of emotion regulation strategies. A survey asked Argentinian citizens (n = 1507, 356 men) about frequency and quantity of alcohol or marijuana use on each day of a typical week, as well as anxiety, stress, and depression symptoms (DASS-21), impulsivity-like traits (UPPS-P), and emotion regulation strategies (ERQ). The 2-month prevalence of alcohol or marijuana use was 80.1%, and 27.2%, respectively. Premeditation was significantly (p < 0.05) and negatively associated with both frequency and quantity of alcohol consumed, whereas negative and positive urgency were positively and significantly (p < 0.05) associated with quantity of alcohol or marijuana use, respectively. Greater depression symptoms predicted greater quantity of alcohol use, whereas lower emotional suppression or lower cognitive reappraisal were significantly (p < 0.05) associated with a greater frequency of alcohol or marijuana use. Sensation seeking was significantly (p < 0.05) and positively associated with frequency of marijuana use. Individuals with higher levels of impulsivity-like traits, higher levels of depression, or lower use of emotional regulation abilities appeared to be at a higher risk of alcohol or marijuana use. In this sample, the use of alcohol (though not marijuana) seems to fit a negative reinforcement pathway. The study suggests that individuals with risk factors for drug misuse could benefit from interventions aimed at enhancing emotion regulation.

Negative urgency as a state-level process

OBJECTIVE

Test whether global self-reports of urgency moderated the within-person associations of affect and impulsive behaviors.

BACKGROUND

Negative urgency is a personality trait that is a risk factor for a range of psychopathology. Although it is assumed that global self-reports of urgency measure individual tendencies to act more impulsively in the face of negative emotions, evidence from ecological momentary assessment studies is mixed.

METHOD

In this Registered Report, we used ecological momentary assessment data from a large sample of young adults (n = 496, age 18-22, 5 surveys per day for 40 days).

RESULTS

All forms of momentary impulsivity were impaired in moments when people reported more intense negative emotions, but global self-reports of urgency did not explain individual differences in this association. Moreover, averaged affective states, rather than specific dimensions, affective circumplex, or appraisals, best predicted impulsive states.

CONCLUSIONS

Results suggest that face-valid interpretations of global self-report of urgency are inaccurate, and it may be important to understand how some people come to understand themselves as high on urgency rather than assuming that people's self-reports of their motivations are accurate. Momentary experiences of emotions globally impact multiple weakly to moderately associated impulsive behaviors, and future research should seek to understand both when and for whom these associations are strongest.

Differentiating action from inaction: Longitudinal relations among impulsive personality traits, internalizing symptoms, and drinking behavior

BACKGROUND

Impulsive personality traits are strong, consistent risk factors for heavy drinking, and modern theories suggest that impulsive traits may also confer risk for internalizing symptoms. However, it remains unclear which specific impulsive traits are linked with heavy drinking versus internalizing symptoms, and whether heavy drinking and internalizing symptoms are mechanisms of risk for negative alcohol consequences in impulsive individuals.

METHOD

Data are from a longitudinal study of young adults (N = 448, Mage = 22.27, 43.5 % female) assessed at baseline (T1), 6 months (T2), and one year later (T3). Longitudinal path models tested whether T1 impulsive traits (i.e., lack of premeditation, lack of perseverance, sensation seeking, positive urgency, negative urgency) were indirectly associated with T3 negative alcohol consequences through heavy T2 drinking and T2 internalizing symptoms (i.e., depression, anxiety, stress). Separate models were tested for positive and negative urgency given strong correlations between these measures.

RESULTS

Across models, T1 lack of premeditation indirectly predicted more T3 negative alcohol consequences through heavy T2 drinking. When tested separately, T1 negative urgency indirectly predicted more T3 negative consequences through higher T2 stress and depressive (but not anxiety) symptoms, and T1 positive urgency predicted higher T2 anxiety symptoms, but T2 anxiety was unrelated to T3 negative consequences. Across models, T1 sensation seeking indirectly predicted less T3 negative consequences through decreased T2 depression.

CONCLUSIONS

Distinct impulsive traits prospectively predicted heavy drinking and internalizing symptoms, both of which conferred risk for negative alcohol consequences. Findings underscore the importance of targeted interventions based on personality and suggest that decreases in drinking may be more effective prevention for those who lack premeditation, whereas decreases in internalizing, particularly depression/stress, may be critical for those high in negative urgency.

Genome-wide association studies (GWAS) and post-GWAS analyses of impulsivity: A systematic review

Impulsivity is related to a host of mental and behavioral problems. It is a complex construct with many different manifestations, most of which are heritable. The genetic compositions of these impulsivity manifestations, however, remain unclear. A number of genome-wide association studies (GWAS) and post-GWAS analyses have tried to address this issue. We conducted a systematic review of all GWAS and post-GWAS analyses of impulsivity published up to December 2023. Available data suggest that single nucleotide polymorphisms (SNPs) in more than a dozen of genes (e.g., CADM2, CTNNA2, GPM6B) are associated with different measures of impulsivity at genome-wide significant levels. Post-GWAS analyses further show that different measures of impulsivity are subject to different degrees of genetic influence, share few genetic variants, and have divergent genetic overlap with basic personality traits such as extroversion and neuroticism, cognitive ability, psychiatric disorders, substance use, and obesity. These findings shed light on controversies in the conceptualization and measurement of impulsivity, while providing new insights on the underlying mechanisms that yoke impulsivity to psychopathology.

Risky alcohol use during youth: Impact on emotion, cognitive networks, and resting-state EEG activity

The identification of the risk factors of alcohol consumption in youths is crucial for early interventions focused on reducing harmful alcohol use. In our study, 82 college students (40 healthy control (CO group) and 42 with risky alcohol use (RAU group) determined by AUDIT questionnaire) between the ages of 18 and 25 years underwent a comprehensive neuropsychological assessment covering emotional and cognitive functioning. Their resting-state activity was also recorded with an EEG for 10 min with their eyes open (EO) and 10 min with their eyes closed (EC) and analyzed using the Fitting Oscillations & One-Over-F (FOOOF) paradigm. After adjusting for sex, those in the RAU group had higher emotional dysregulation and impulsivity traits. The RAU girls presented more emotional regulation problems, such as dysregulation and negative urgency compared with the RAU boys. The RAU youths had significantly worse functioning in several cognitive domains, such as sustained attention, verbal memory, and executive functions. Cognitive network analysis revealed a different pattern of connections in each group showing that in the RAU group, the verbal memory domain had the highest connection with other cognitive functions. The EEG analyses did not reveal any significant differences between the CO and the RAU groups. However, we observed only in the EO condition that boys the from the RAU group displayed a higher theta/beta ratio than the RAU girls, whereas these differences were not observed within the CO group. Our findings highlight the need to explore more deeply the emotional, cognitive and brain changes underlying the RAU in young people.

Pregaming potentiates risk between UPPS-P impulsivity and day-level drinking behavior: A test of person-environment transactions theory

Pregaming represents a uniquely high-risk drinking event for young adults, and subfacets of impulsivity are robust predictors of alcohol use and related negative outcomes. Further, it is likely that pregame events contain social and physical stimuli that are particularly appealing for impulsive individuals, thus exacerbating risk for negative outcomes. However, no prior studies have investigated the extent to which impulsive personality traits interact with pregame events to confer alcohol-related risk. Thus, the present study examined the extent to which UPPS-P (urgency-perseverance-premeditation-sensation seeking-positive urgency) subfacets of impulsivity interact with the occurrence of pregaming to predict relations between pregaming, drinking quantity, and negative alcohol-related outcomes. College students (N = 737) completed a modified, online version of the 30-day Timeline Followback in which they reported drinking quantity, negative consequences, and whether they engaged in pregaming on a given day. Results indicated that sensation seeking and a lack of premeditation moderated relations between pregaming and drinking quantity such that those who are higher in sensation seeking and lower in their ability to plan ahead drank more on pregaming days. Sensation seeking and positive urgency moderated relations between pregaming and negative consequences such that those who are higher in positive urgency experience more consequences on pregaming days whereas those who are higher in sensation seeking experience less consequences. Future studies may benefit from more granular assessments of pregame-related risk as subfacets of impulsivity may confer momentary risk. Prevention efforts targeting the reduction of pregaming frequency, particularly among impulsive individuals, may lower overall risk for heavy drinking.

Changes in substance use, recovery, and quality of life during the initial phase of the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic disrupted lives on a massive scale. While the pandemic appeared to worsen mental health outcomes broadly, its effects on alcohol/substance use and recovery are unclear. Many studies convolved the sociopolitical unrest beginning in May 2020 with the pandemic. We assessed pandemic-related changes in substance use, recovery involvement, and quality of life among US adults at two specified time periods that isolated pandemic effects from potentially confounding sociopolitical factors.

OBJECTIVES

We tested the following hypotheses: the pandemic and consequent policies (1) increased use of alcohol and illicit substances in active users; (2) increased use of alcohol/substances among people in early recovery; (3) reduced participation in recovery activities among those in early recovery, and that (4) use amount and use events correlated with impulsivity in both groups and that (5) substance use and abstinence correlated with resilience.

METHODS

We recruited 1,685 participants through Amazon's Mechanical Turk (MTurk). We assessed demographics, quality of life, alcohol/substance use, recovery activities, and measures of impulsivity and resilience at two time points, pre-pandemic and (early) during-pandemic. Only n = 45 (Active Users; males n = 32) and n = 34 (Recovery; males n = 20) passed data quality checks and were included in the primary analyses.

RESULTS

Among Active Users, weekly alcohol consumption and days spent using alcohol and illicit substances decreased during the pandemic. Resilience negatively correlated with pandemic-related substance use in early recovering participants. Significant reduction in the quality of life was coincident with a trend of lower recovery activity participation (31% decline) during the pandemic.

CONCLUSIONS

The reduced alcohol/substance use and participation in recovery activities might be expected from conditions that promote social isolation. The high prevalence of low-quality data from MTurk cautions for careful use of online data sourcing.

The clinical significance of emotional urgency in bipolar disorder: a scoping review

BACKGROUND

Emotional urgency, defined as a trait concept of emotion-based impulsivity, is at least moderately associated with general psychopathology. However, its clinical significance and associations with clinically relevant features of bipolar disorder remain unclear. This scoping review aims address this gap by determining the extent of evidence in this niche scope of study.

METHODS

Evidence of between-group differences of positive and negative urgency, its associations with mood severity, and all peripheral associations related to illness and psychosocial outcomes were synthesized based on PRISMA checklists and guidelines for scoping reviews (PRISMA-ScR).

DESIGN

Electronic databases were searched for articles published between January 2001 and January 2024. A total of 1013 entries were gathered, and a total of 10 articles were included in the final selection after the removal of duplicates and ineligible articles.

RESULTS

Differences in urgency scores between bipolar disorder and healthy controls were large (Cohen's d ranged from 1.77 to 2.20). Negative urgency was at least moderately associated with overall trauma, emotional abuse, neglect, suicide ideation, neuroticism, and irritable/cyclothymic temperament, whereas positive urgency was at least moderately associated with various aspects of aggression and quality of life. Positive but not negative urgency was associated with quality of life in bipolar disorder.

CONCLUSION

Large between-group differences found for emotional urgency in bipolar disorder imply large clinical significance. Emotional urgency was associated with worse clinical features and outcomes. Given the high clinical heterogeneity of the disorder, emotional urgency may be an important phenotype indicative of greater disorder severity.

Trait impulsivity moderates rate of alcohol consumption in daily life

INTRODUCTION

Rate of alcohol consumption, the speed with which people drink, has been linked to a range of outcomes, including alcohol use disorder symptoms and increased positive affect. However, minimal work has identified who is most likely to drink at elevated rates. Impulsivity is associated with increased attention to positive reinforcers specifically (e.g., positive affect). We therefore examined whether people higher in trait impulsivity engage in faster consumption during drinking episodes.

METHODS

Participants were current drinkers (N = 113; 54 people with borderline personality disorder [BPD], a disorder that involves elevated impulsivity, and 59 community people) who completed a 21-day ecological momentary assessment (EMA) protocol. Multilevel models of drinking episodes (Nobservations = 3,444) examined whether self-reported trait impulsivity, measured at baseline, was associated with faster rise in estimated blood alcohol concentration (eBAC) at each follow-up period.

RESULTS

All UPPS sub-scales were associated with faster rise in eBAC across a drinking episode. In a multivariate model including all sub-scales as simultaneous predictors, sensation seeking and (lack of) perseverance were independently positively associated with rate of consumption. Additional analyses indicated that greater negative urgency and sensation seeking were associated with faster rises in eBAC in participants with BPD, relative to community comparisons.

CONCLUSION

In a sample that captured a wide spectrum of impulsivity, greater impulsivity was associated with drinking alcohol at a faster rate. People higher in sensation seeking and (lack of) perseverance may be prone to drink at faster rates out of a desire to maximize the hedonic effects of alcohol.

PUBLIC SIGNIFICANCE STATEMENT

This study finds that people who are more impulsive tend to drink alcohol faster, putting them at greater risk for negative consequences. This may explain, in part, why impulsivity is linked to experiencing alcohol-related problems.

Differences in the relation of binge drinking and prescription drug misuse to suicide ideation and attempts between college-aged adults and adults above the age of 25: Findings from the 2015-2019 National Survey on Drug Use and Health (NSDUH)

OBJECTIVE

To clarify the role of age in risk associated with drug misuse and binge drinking, this study examines the differential relations of binge drinking and prescription drug misuse to risk of suicidal ideation and attempts in young adults of college age (18-24) compared to those above the age of 25.

METHODS

We used data from the National Survey on Drug Use and Health (NSDUH) for the years 2015 through 2019 (N = 269,078).

RESULTS

The study found that, for adults above college age, the presence of any past-month binge drinking was associated with a higher likelihood of past-year suicide ideation (b = 0.427, OR = 1.532, 95%CI [1.388, 1.692]) and attempts (b = 0.637, OR = 1.891, 95%CI [1.271, 2.813]) compared to college-aged adults. Similarly, past-month prescription drug misuse showed stronger associations with past-year suicide ideation (b = 0.831, OR = 2.297, 95%CI [1.952, 2.701]) and attempts (b = 0.539, OR = 1.715, 95%CI [1.264, 2.327]) in adults above college age.

CONCLUSION

These findings highlight that binge drinking and prescription drug misuse appears to become more strongly associated with suicide ideation and attempts after adults age beyond young adulthood.

The mediating effect of dispositional mindfulness on the association between UPPS-P impulsivity traits and gaming disorder among Asia-Pacific young adults

BACKGROUND

Little evidence is available to verify the mediating effect of dispositional mindfulness on the association between gaming disorder and various impulsivity traits. The present study aimed to investigate the mediating effect of dispositional mindfulness on the association between the five UPPS-P impulsivity traits and the risk of gaming disorder among young adults.

METHODS

It was an inter-regional cross-sectional study using online survey in Australia, Japan, The Philippines and China. Impulsivity measured by the UPPS-P Impulsive Behavior Scale-Short version; dispositional mindfulness measured by the Mindfulness Attention Awareness Scale; and the risk of gaming disorder measured by the Internet Gaming Disorder Scale were collected in the focal regions. Structural equation modeling was performed by SPSS AMOS version 26 to verify the study hypotheses. Bootstrapped 95% confidence interval was reported. Statistical significance was indicated by the p-value below 0.05.

RESULTS

Among the 1,134 returned questionnaires, about 40% of them aged 18-20 years and 21-23 years, respectively. 53.8% were male. 40.7% had been playing digital and video games for over 10 years. The prevalence of gaming disorder was 4.32%. The model fitness indices reflected that the constructed model had an acceptable model fit (χ2(118) = 558.994, p < 0.001; χ2/df = 4.737; CFI = 0.924; TLI = 0.890; GFI = 0.948; RMSEA = 0.058; SRMR = 0.0487). Dispositional mindfulness fully mediated the effect of positive urgency and negative urgency on the risk of gaming disorder. The effect of lack of premeditation on the risk of gaming disorder was partially mediated by dispositional mindfulness. However, dispositional mindfulness did not mediate the effect of sensation seeking on the risk of gaming disorder.

CONCLUSIONS

The varied associations between dispositional mindfulness and the five impulsivity traits hints that improving some impulsive traits may increase dispositional mindfulness and so lower the risk of gaming disorder. Despite further studies are needed to verify the present findings, it sheds light on the need to apply interventions on gamers based on their impulsivity profile. Interventions targeting at emotion regulation and self-control such as mindfulness-based interventions seem to be effective to help gamers with dominant features of urgency and lack of premeditation only. Other interventions shall be considered for gamers with high sensation seeking tendency to enhance the effectiveness of gaming disorder prevention.

Impulsivity mediates the association between narcissism and substance-related problems beyond the degree of substance use: a longitudinal observational study

BACKGROUND

Narcissism has been implied as a putative risk factor for substance use disorders (SUDs). However, previous research did not disentangle the degree of substance use from substance-related problems, the symptoms of SUDs. This preregistered study addressed the open question whether grandiose and vulnerable narcissism and their constituent traits convey specific SUD risk, that is, explain substance-related problems beyond the degree of use. Furthermore, we tested whether impulsivity or substance use motives linked to narcissistic self-regulation mediate this association.

METHODS

Narcissism, impulsivity, substance use motives, past-year substance use, and substance-related problems were assessed in 139 (poly-)substance users, 121 of whom completed a one-year follow-up. For significant longitudinal associations between narcissism factors and substance-related problems controlled for the degree of use, we tested impulsivity and substance use motives as mediators.

RESULTS

Grandiose narcissism (r =.24, p =.007) and its constituent factors antagonistic (r =.27, p =.003) and agentic narcissism (r =.18, p =.050), but not vulnerable narcissism, prospectively predicted substance-related problems beyond the degree of substance use. Associations of grandiose narcissism and antagonistic narcissism with substance-related problems were fully mediated by impulsivity, but not substance use motives. Impulsivity explained roughly one third of the association of both grandiose (P̂M = 0.30) and antagonistic narcissism (P̂M = 0.26) with substance-related problems.

DISCUSSION

We demonstrate that grandiose narcissism- particularly antagonistic but also agentic narcissism- is specifically linked to substance-related problems beyond the degree of substance use. The mediating effect of impulsivity but not substance use motives suggests that impulsivity may be a more important mechanism than narcissistic self-regulation in promoting SUD in narcissism. However, future studies may use more targeted measures than substance use motives to further probe the role of self-regulation. Similar result patterns for alcohol compared to all substances together indicate that mechanisms may be alike across substances. In conclusion, narcissistic individuals may not use substances more but have a higher SUD risk, informing prevention and treatment.

Longitudinal Relations Among Parental Substance Use Disorder and Adolescent Drinking Behavior: The Role of Temperament, Negative Urgency, and Maternal Parenting

Research suggests that parental substance use disorder is associated with adolescent drinking indirectly through negative urgency, a form of impulsivity that is particularly associated with high-risk drinking. Moreover, childhood mechanisms of risk may play a role in this developmental chain such that childhood temperament and parenting may be mechanisms through which parental substance use disorder is associated with adolescent negative urgency and drinking behavior. Therefore, the current study tested whether parental substance use disorder was indirectly associated with adolescent drinking frequency through childhood temperament (i.e., "dysregulated irritability") and adolescent negative urgency, and whether relations differed by levels of maternal support and consistency of discipline. Data come from a multigenerational, longitudinal study of familial substance use disorder (N = 276, Mage in childhood = 6.28 (SD = 1.16), Mage in adolescence = 15.86 (SD = 1.56), 45.3% female). Findings indicated that parental substance use disorder indirectly predicted adolescent drinking through both childhood dysregulated irritability and adolescent negative urgency (mediated pathways). This indirect relation was stronger at higher vs. lower levels of maternal support but did not vary by maternal consistency of discipline. Parental substance use disorder also indirectly predicted adolescent drinking separately through childhood dysregulated irritability and negative urgency. Findings thus suggest that childhood dysregulated irritability may be an early marker of risk toward high-risk personality traits and behavior in adolescence that are associated with having a parental history of substance use disorder. Findings also suggest that increased maternal support may only be helpful in buffering risk for those with low levels of dysregulated irritability. Prevention efforts focused on childhood emotion regulation and emotion-based action may be useful in preventing adolescent risk behavior.

Restrained eating and alcohol use: Testing drinking to cope and impulsivity as moderators

The association between restrained eating and alcohol use remains poorly understood among undergraduates. Consistent with tension reduction theory, individuals with disordered eating may be motivated to drink alcohol to cope with negative emotionality. Perhaps what pushes them to drink despite restriction goals is impulsivity. The combined impact of drinking to cope and impulsivity on the theoretically complex link between restrained eating and alcohol outcomes has not been previously examined. The current study tested the moderating effect of drinking to cope and impulsivity on the association between restrained eating and alcohol use and problems. Undergraduates (N = 1,619) self-reported on eating disorder symptoms, alcohol use motives, impulsivity, and alcohol outcomes. A moderation model revealed that restrained eating predicted past 30-day alcohol use, but only for women high in both drinking to cope and impulsivity. These findings help characterize alcohol misuse risk among young adults who restrict their eating, thereby, results may inform interventions.

Characterizing the dimensions of positive emotion functioning in young adult alcohol use and alcohol-related problems

Emotional functioning figures prominently in most contemporary models of alcohol use (Kassel & Veilleux, 2010). These models posit that alcohol use becomes reinforced due to its ability to regulate a person's affect (Sher & Grekin, 2007). A growing body of literature suggests that for youth, positive reinforcement (i.e., using alcohol to enhance positive feelings or to increase their duration) is a leading mechanism facilitating increased use (Emery & Simons 2020; Howard et al., 2015). However, few, if any, studies have examined the unique associations between multiple indicators of positive emotional functioning and alcohol use as well as alcohol-related problems. We aimed to fill this gap by using secondary data from large college student sample (N = 402) to characterize the unique associations between trait indicators of positive emotional functioning (i.e., positive affect, anhedonia, savoring, positive emotion dysregulation) and alcohol use as well as alcohol-related problems. Results indicated trait positive emotion dysregulation (difficulty managing intense positive emotions) was positively related to both alcohol consumption (IRR = 1.03, p =.019) and alcohol-related problems (IRR = 1.03, p =.001). Interestingly, trait savoring (i.e., ability to increase the intensity/duration of positive emotions) was positively related to alcohol consumption (IRR = 1.18, p =.049) and inversely related to problems (IRR = 0.86, p =.019). None of the other positive emotion indicators were significantly associated with either alcohol use or problems.

Clinical differences between outpatients with and without internet addiction and emotional disorders: a prospective naturalistic outcome study

Background/Objective

as internet use becomes increasingly ingrained in contemporary society, internet addiction (IA) has emerged as a global public health concern. There is ongoing debate regarding whether IA represents a distinct psychological disorder or a secondary manifestation of other existing disorders. This study aimed to examine the pathological relationship between IA and emotional disorders (ED).

Method

this study compared pre-treatment characteristics and treatment process of three groups of patients (N=1292) in a naturalistic treatment setting: IA only, ED only, and comorbidity of IA and ED.

Results

the IA only group differed from the other groups by reporting the highest levels of life satisfaction, adaptive emotion regulation, as well as risk behavior urges at intake. In addition, the IA only group displayed the lowest level of depressive and anxiety symptoms throughout the treatment.

Conclusion

our findings contribute to a better understanding of the discreteness of IA as a potential psychological disorder and inform more effective treatment strategies for IA and its comorbid conditions.

The influence of negative urgency and mood inductions on alcohol cognitions

BACKGROUND

Negative urgency (NU), the tendency to act rashly during negative emotional states, is a robust risk factor for alcohol misuse that is posited to function in part through alcohol-related cognitions. Nonetheless, relatively little research has examined mood-based fluctuations in such cognitions, which could help to explain how the trait of NU translates to impulsive alcohol-related behaviors. We examined how NU impacted several alcohol cognitions (positive/negative alcohol expectancies, positive/negative alcohol valuations, and alcohol craving for positive/negative emotional reinforcement) before and after negative, neutral, or positive mood inductions. We hypothesized that NU would predict greater and more favorable endorsement of alcohol and its effects following negative (vs. positive or neutral) mood induction.

METHODS

Participants (N = 428) were southern-midwestern college students recruited for an online experiment. Following the provision of consent, participants rated NU and preinduction alcohol cognitions, and were then randomly assigned to one of three (negative, neutral, or positive) mood inductions; subsequently, postinduction alcohol-cognition ratings were immediately obtained. We conducted six robust multilevel linear models (one per DV) examining NU's influence on within-person changes in alcohol cognitions across each mood induction.

RESULTS

No three-way interactions were identified and only one two-way interaction involving NU was identified. There were main effects across mood induction conditions and time points for NU predicting greater endorsement of positive and negative alcohol outcome expectancies, and greater alcohol craving for positive and negative emotional reinforcement.

CONCLUSIONS

Greater NU predicts greater perceived likelihood of alcohol's effects, alongside greater desire for mood improvement from alcohol. The absence of three-way interactive effects indicates NU's influence on mood-dependent fluctuations in alcohol cognitions may manifest over longer timescales (e.g., months and years), involve alternative cognitive processes (e.g., drinking motives and implicit alcohol cognitions), and apply more broadly to desires for mood improvement than purely negative emotional reinforcement.

A study of the interactive mediating effect of ADHD and NSSI caused by co-disease mechanisms in males and females

Background

Non-suicidal self-injury (NSSI), of which the predisposing factors are complex and diverse, profoundly affects the physical and mental health of young people. Therefore, this work established an NSSI intermediary network model considering the interaction of multiple factors. A mediating effect between attention-deficit/hyperactivity disorder (ADHD) and NSSI, considering the influence of comorbidities, such as depression, anxiety, and impulsive personality, was proposed based on sex differences.

Methods

A total of 2,689 middle school students in Ningbo City, Zhejiang Province, China, were randomly sampled and participated in this study. Data regarding their demographic characteristics, attention deficit, hyperactivity/impulsivity, NSSI, anxiety, depression, internet addiction, and other comorbid symptoms were collected and analyzed. After initially screening the data, variables were assessed for significance using a single-factor inter-group difference analytic method, and a binary logistic regression analysis was performed. The intermediary effect of factors influencing NSSI in males and females was also analyzed.

Results

The overall NSSI rate was 15.16%. The results showed that the impact of individual impulsivity characteristics (impulsiveness, the ADHD with hyperactivity/impulsivity subtype) on NSSI behavior was not significant (regression results, P > 0.05). The degree of association between ADHD with attention deficit and ADHD with comprehension deficit subtypes, and other comorbid symptoms (depression, anxiety, and internet addiction disorder) and NSSI, with odds ratios (ORs) of 7.6/6.42/436.68/3.82/1.86, and 95% bootstrap confidence intervals (CIs) of 4.64, 12.87/3.46, 12.67/137.42, 2659.13/2.32, 6.37/1.31, 2.82, respectively. The results also showed significant effects of ADHD subtypes on comorbid symptoms and the path effects of NSSI (P < 0.01). Among them, the mediating effect was the strongest when anxiety was the mediating variable, and the mediating effect of girls was higher than that of boys.

Conclusion

The results of this work demonstrated the influence of ADHD symptoms on NSSI behavior. Among patients with ADHD, patients with subtypes with obvious attention deficit characteristics were more likely to exhibit NSSI behavior, whereas the hyperactive impulse subtype had no direct impact on NSSI. We conclude that adolescent impulsivity may not be directly related to NSSI behavior and that impulsive characteristics jointly affect NSSI behavior through a series of NSSI comorbid symptoms. Notably, the probability of symptom onset and the degree of comorbidity was significantly higher in girls than in boys of the same age, and girls were more prone to NSSI behavior. These findings provide effective theoretical support for the prevention and treatment of adolescent NSSI behavior.

Too Tired to Think: Within and Between-Person Relations Among Impulsive Traits, Sleep Duration, and Mental Health Outcomes

Heavier drinking and depression are common mental health concerns in the USA, yet few studies have sought to understand transdiagnostic risk factors for both. Two health-focused risk factors are impulsive personality traits and sleep duration, but research typically separates the two, precluding additive and interactive relations. The current study sought to test a theoretical model where risk conferred from impulsive traits is heightened when individuals have reduced sleep. Public-access data from the National Longitudinal Study on Adolescent to Adult Health (Add Health) were used to test study hypotheses. Participants reported on impulsive traits (i.e., lack of premeditation, sensation seeking), sleep duration, depression, and drinking across three waves spanning adolescence, emerging adulthood, and adulthood. Multilevel models distinguished risk processes at the between- vs. within-person level. At the between-person level, sensation seeking predicted drinking whereas premeditation predicted depression. Additionally, within-person deviations in both traits were associated with drinking, whereas within-person deviations in premeditation were associated with depression. Sleep duration was protective against outcomes at both levels. However, main effects were qualified by interactions at both levels, such that having below average sleep duration heightened the effects of premeditation at the between-person level, whereas within-person decreases in sleep heightened the effects of sensation seeking at the within-person level. Findings support a theoretical model where poor sleep exacerbates risk conferred from impulsive traits. Risk conferred from impulsive traits diverged based upon level of analysis, suggesting that global and just-in-time interventions may benefit from targeting specific impulsive traits as well as sleep.

Strength of Pornography Craving Experience (PCE-S): Psychometric properties of a new measure based on the elaborated intrusion theory of desire

INTRODUCTION

Pornography use is a common sexual activity with potentially addictive use in some people. Even though craving is being recognized as an important characteristic of addictive behaviors, there is a lack of a specific validated instrument measuring the pornography craving experience. The present study aimed at adapting and validating an instrument measuring the users' strength of pornography craving experience (PCE-S) based on the Elaborated Intrusion theory of desire.

METHODS

Items from the "strength" form of the Craving Experience Questionnaire (CEQ) were adapted to pornography use and used to create the PCE-S. The PCE-S was then administered online to 1584 English-speaking cyberporn users aged 18-75 years old (M = 33.18; SD = 10.84]; 63.1 % male, 35.2 % female, and 1.7 % non-binary). All participants completed an assessment of compulsive cyberporn use (CIUS adapted for cyberporn). Confirmatory factorial analysis (CFA) was used to examine the construct structure validity; Cronbach alpha coefficient, corrected item-total correlation, regression, and discriminant analysis were used to assess the instrument's psychometric properties.

RESULTS

After using the modification indices to improve the initial model, a relatively good fit for the three-factor model was confirmed. Concurrent validity with the compulsive cyberporn use (CCU) measure was demonstrated. The PCE-S discriminated between participants with high CCU and those with low CCU scores.

CONCLUSIONS

A specific pornography craving experience instrument scale, based on the Elaborated Intrusion theory of desire seems to capture key constructs of the theory and correlate with measures of compulsive cyberporn use.

Cannabis use in context: Relations among impulsive personality traits, context, and cannabis problems

INTRODUCTION

Impulsive personality traits are associated with cannabis problems. Person-Environment Transactions Theory suggests that highly impulsive individuals behave differently in certain contexts, however little research has focused on the context in which cannabis is used. Therefore, the current study tested whether impulsive traits moderated relations between cannabis use contexts (social vs. solitary) and cannabis problems.

METHOD

In this cross-sectional study, college student who use cannabis (N = 435; 60.7% female) reported on their impulsive traits (i.e., negative urgency, positive urgency, premeditation, perseverance, and sensation seeking), typical cannabis use context (i.e., alone, with friends), typical cannabis use frequency, and past 30-day cannabis problems.

RESULTS

Both solitary cannabis use and negative urgency were associated with more cannabis problems. There were significant interactions between negative urgency and solitary cannabis use and lack of perseverance and solitary cannabis use, such that high and mean (but not low) levels of both negative urgency and lack of perseverance were associated with more cannabis problems the more frequently an individual used cannabis alone. There was also a significant interaction between sensation seeking and social cannabis use, such that high and mean (but not low) levels of sensation seeking were associated with cannabis problems for individuals who used cannabis more socially.

CONCLUSIONS

Findings suggest that impulsivity may potentiate risk for cannabis problems depending on the context in which cannabis is used. Prevention efforts may benefit from targeting protective strategy use in certain cannabis use contexts based upon an individual's personality traits.

The effect of mindfulness on decision-making, inhibitory control, and impulsivity of substance use disorder in-treatment patients: A randomized clinical trial

This study aimed to investigate the effects of Mindfulness-Based Relapse Prevention (MBRP) in decision-making, inhibitory control and impulsivity compared to Treatment as Usual (TAU) for individuals with Substance Use Disorders (SUD's) in Brazil. A randomized clinical trial was conducted with participants from a therapeutic community (n = 122). Decision-making (Iowa Gambling Task), impulsivity dimensions (UPPS-P Scale), and inhibitory control (Stroop Color-Word Test) were assessed before and after the MBRP 8-week intervention. GLM Multivariate analysis was used to evaluate the effects of MBRP on different impulsivity measures. The results showed that MBRP+TAU improved the general decision-making score (p = 0,008) compared to TAU. However, no significant effects were found in impulsivity dimensions and inhibitory control in individuals with SUDs in the therapeutic community. This study found improvement in decision-making in the total IGT score; however, no effect for self-reported impulsivity and inhibitory control among middle-aged patients after an 8-weeks intervention of MBRP protocol in an inpatient setting. It adds information to the subject, with implications and possible directions to be followed by the next clinical trials with patients with SUDs in treatment.

The Relations Between an Inventory-Based Measure of Executive Function and Impulsivity Factors in Alcohol- and Cannabis-Relevant Outcomes

OBJECTIVE

While the lack of relation between performance- and inventory-based executive function (EF) measures is well documented, there remains ambiguity between self-report EFs and closely related constructs (e.g., impulsivity) assessed via the same method. The degree of convergence between purported EF measures with similar yet distinct constructs contain important theoretical implications for available EF assessment strategies and their construct validity. A newer measure of EF, the Behavior Regulation Inventory of Executive Functions-Adult (BRIEF-A), allows for more direct comparisons to self-reported measures of impulsivity, such as the commonly used Urgency, Planning, Perseverance, Sensation Seeking-Positive Urgency (UPPS-P) assessment.

METHOD

The present study used factor analysis and hierarchical regression to explore the associations between the BRIEF-A and UPPS-P, using alcohol and cannabis consumption across various outcomes (i.e., quantity-frequency and consequences) as an external criterion. Participants were 339 undergraduate students (Mage = 19.35; Female = 63%) from a large southwestern university.

RESULTS

The BRIEF-A and UPPS-P demonstrated strong correlations at both higher- and lower order facets. While the BRIEF-A was a significant correlate to many substance use outcomes, these relations were generally weaker than those seen with the UPPS-P. Hierarchical regression suggested limited contributions of the BRIEF-A over and above the UPPS-P.

CONCLUSIONS

Overall, this study suggested substantial overlap between impulsigenic factors and EFs when measured by self-report, and limited utility of EF measures to account for unique variance with substance use outcomes in this sample.

Who affiliates with SMART recovery? A comparison of individuals attending SMART recovery, alcoholics anonymous, both, or neither

BACKGROUND

Mutual-help organizations (MHOs) play a crucial role for many individuals with alcohol use disorder (AUD) or other substance use disorders in achieving stable remission. While there is now substantial research characterizing who uses 12-step MHOs, very little is known about who becomes affiliated with newer and rapidly growing MHOs, such as Self-Management and Recovery Training ("SMART" Recovery). More research could inform knowledge regarding who may be best engaged by these differing pathways.

METHODS

We conducted a cross-sectional analysis of participants (N = 361) with AUD recruited mostly from the community who were starting a new recovery attempt and self-selected into one of four different recovery paths: (1) SMART Recovery ("SMART-only"; n = 75); (2) Alcoholics Anonymous ("AA-only"; n = 73); (3) Both SMART and AA ("Both"; n = 53); and (4) Neither SMART nor AA ("Neither"; n = 160). We compared the groups on demographics, clinical history, treatment and recovery support service use, and indices of functioning and well-being. We computed descriptives and conducted inferential analyses according to the data structure.

RESULTS

Compared to study participants choosing AA-only or Both, SMART-only participants were more likely to be White, married, have higher income and more education, be full-time employed, and evince a pattern of lower clinical severity characterized by less lifetime and recent treatment and recovery support services usage, lower alcohol use intensity and fewer consequences, and less legal involvement. AUD symptom levels, lifetime psychiatric diagnoses, psychiatric distress, and functioning were similar across MHO-engaged groups.

CONCLUSION

SMART Recovery appears to attract individuals with greater psychosocial stability and economic advantage and less severe histories of alcohol-related impairment and legal involvement. Findings suggest that certain aspects specific to the SMART Recovery group approach, format, and/or contents may appeal to individuals exhibiting this type of profile. As such, SMART appears to provide an additional resource that expands the repertoire of options for individuals with AUD who seek recovery.

Measurement Invariance and Differential Relationship to Substance Use of the Short UPPS-P Impulsive Behavior Scale Across Racial Groups

The Short UPPS-P Impulsive Behavior (SUPPS-P) scale assesses impulsive traits; however, its use among racial/ethnic minorities needs further testing. The aims of this study are to (a) test the measurement invariance of the SUPPS-P scale between White and racial/ethnic minority groups and (b) determine whether impulsive personality traits differentially relate to substance use outcomes across these groups. Participants were 1,301 young adults and recruited through a large public university or Amazon's Mechanical Turk. Multigroup confirmatory factor analysis concluded strong measurement invariance for Black, Asian American, and Hispanic/Latino groups, each compared with a White group. Most relationships between SUPPS-P traits and substance use did not differ across the groups compared, although two differences emerged with alcohol use. The SUPPS-P can validly and reliably measure impulsive traits in Black, Hispanic/Latino, and Asian American young to middle adults. Previous findings on risk patterns with the SUPPS-P likely generalize to these groups.

Drinking motives, personality traits and life stressors-identifying pathways to harmful alcohol use in adolescence using a panel network approach

BACKGROUND AND AIMS

Models of alcohol use risk suggest that drinking motives represent the most proximal risk factors on which more distal factors converge. However, little is known about how distinct risk factors influence each other and alcohol use on different temporal scales (within a given moment versus over time). We aimed to estimate the dynamic associations of distal (personality and life stressors) and proximal (drinking motives) risk factors, and their relationship to alcohol use in adolescence and early adulthood using a novel graphical vector autoregressive (GVAR) panel network approach.

DESIGN, SETTING AND CASES

We estimated panel networks on data from the IMAGEN study, a longitudinal European cohort study following adolescents across three waves (aged 16, 19 and 22 years). Our sample consisted of 1829 adolescents (51% females) who reported alcohol use on at least one assessment wave.

MEASUREMENTS

Risk factors included personality traits (NEO-FFI: neuroticism, extraversion, openness, agreeableness and conscientiousness; SURPS: impulsivity and sensation-seeking), stressful life events (LEQ: sum scores of stressful life events), and drinking motives [drinking motives questionnaire (DMQ): social, enhancement, conformity, coping anxiety and coping depression]. We assessed alcohol use [alcohol use disorders identification test (AUDIT): quantity and frequency] and alcohol-related problems (AUDIT: related problems).

FINDINGS

Within a given moment, social [partial correlation (pcor) = 0.17] and enhancement motives (pcor = 0.15) co-occurred most strongly with drinking quantity and frequency, while coping depression motives (pcor = 0.13), openness (pcor = 0.05) and impulsivity (pcor = 0.09) were related to alcohol-related problems. The temporal network showed no predictive associations between distal risk factors and drinking motives. Social motives (beta = 0.21), previous alcohol use (beta = 0.11) and openness (beta = 0.10) predicted alcohol-related problems over time (all P < 0.01).

CONCLUSIONS

Heavy and frequent alcohol use, along with social drinking motives, appear to be key targets for preventing the development of alcohol-related problems throughout late adolescence. We found no evidence for personality traits and life stressors predisposing towards distinct drinking motives over time.

Longitudinal Investigation of Bidirectional Relations Between Childhood Trauma and Emotion-Driven Impulsivity in the Adolescent Brain Cognitive Development Study

OBJECTIVE

Exposure to childhood trauma is associated with numerous adverse mental health consequences. Addressing important gaps in the existing research, the proposed study clarifies the longitudinal and bidirectional associations between childhood trauma and both negative and positive emotion-driven impulsivity.

METHOD

This study utilized a sample of 11,872 9- to 10-years-olds recruited from 21 research sites across the United States from the Adolescent Brain Cognitive Ddevelopment (ABCD) Study. Childhood trauma was assessed at one- and two-year follow-ups. Negative and positive urgency were assessed at baseline and two-year follow-up. Cross-lagged panel models evaluated the longitudinal and bidirectional associations between childhood trauma and both negative and positive emotion-driven impulsivity.

RESULTS

Findings showed that earlier childhood trauma was associated with higher levels of later negative (β = 0.133, p < .001) and positive (β = 0.125, p < .001) emotion-driven impulsivity. Further, higher levels of earlier positive (β = 0.033, p < .006), but not negative (β = 0.010, p = .405), emotion-driven impulsivity were associated with later childhood trauma. Finally, the strength of the relations between childhood trauma and emotion-driven impulsivity did not differ by sex (ΔX2 = 10.228, p > .05).

DISCUSSION

Identification of both negative and positive emotion-driven impulsivity among children exposed to trauma may serve as a point of intervention to reduce subsequent risk for deleterious health outcomes.

Anhedonia and impulsivity in college alcohol use: A path analysis

OBJECTIVE

Alcohol use is a substantial problem among college students and has several negative consequences. The current study examined the associations between anhedonia and alcohol use and related problems via impulsive behavior (e.g., negative urgency, sensation seeking). We parsed anhedonia into four specific facets: consummatory, anticipatory, recreational, and social anhedonia.

PARTICIPANTS

Six hundred and forty college students aged 18-25 were included in the final analysis.

METHOD

Data were collected via Amazon Mechanical Turk. Self-report inventories assessing for anhedonia, alcohol use, impulsive behavior, and depressed mood were utilized.

RESULTS

Recreational consummatory anhedonia was negatively associated with alcohol use and alcohol-related problems through negative urgency. Recreational consummatory anhedonia also had significant negative associations with alcohol consumption via sensation seeking. Further, social anticipatory anhedonia was positively associated with alcohol use and related problems via negative urgency.

CONCLUSIONS

This study highlights important associations between anhedonia, impulsivity, and alcohol use and related problems.

Ghrelin and impulsivity relationship in alcohol-dependent patients and healthy individuals

AIMS

Abundant research indicates that ghrelin hormone levels are associated with alcohol use and addiction. One of the mediators of this association may be impulsivity, which is one of the common traits observed in alcohol addiction and some eating disorders. This study evaluated participants with alcohol dependency and healthy volunteers to determine whether trait impulsivity and ghrelin levels are associated.

METHODS

This study analyzed trait impulsivity scores and fasting serum ghrelin levels of 44 males with alcohol dependency and 48 healthy male participants. The Barratt Impulsiveness Scale and the UPPS Impulsive Behaviour Scale (UPPS) were used to measure trait impulsivity levels. Penn Alcohol Craving Scale and Yale Brown Obsessive Compulsive Drinking Scale for heavy drinking were used to assess craving at the baseline and after the detoxification period.

RESULTS

Alcohol-dependent patients' fasting ghrelin levels were significantly higher than that of healthy participants. Ghrelin plasma levels were positively correlated with UPPS total impulsivity scores and sensation-seeking among healthy individuals. In alcohol-dependent participants, there was a positive correlation between UPPS urgency scores obtained at the baseline and fasting ghrelin levels before and after the detoxification period.

CONCLUSIONS

Ghrelin-impulsivity relationship could be observed in certain dimensions of impulsivity in both alcohol-dependent and healthy individuals and even independent of the effect of alcohol. Although the associated impulsivity dimensions differ in different groups, the results are parallel to other studies in terms of demonstrating the relationship between ghrelin and impulsivity.

The Complexity of Impulsivity Dimensions among Abstinent Individuals with Substance Use Disorders

Impulsivity is a complex construct that has been operationalized considering personality dimensions (e.g., negative urgency [NU], lack of perseverance [LPe], lack of premeditation [LPr], positive urgency [PU]), and neuropsychological processes (i.e., cognitive disinhibition, motor disinhibition, impulsive decision-making). Empirical research suggested that they could represent core features of substance use disorders (SUDs). However, there are no studies that have comprehensively assessed them among patients with SUDs. Furthermore, the quality of relationships among such domains remains unclear. The current case-control study included 59 abstinent patients with SUDs and 56 healthy controls (HCs). There were two independent assessment phases: i) the administration of UPPS-P impulsive behavior scale; ii) a computerized neuropsychological battery (i.e., Attentional Network Test, Go/No-Go task, Iowa Gambling task). Patients with SUDs reported higher levels of NU and PU than HCs. NU, LPe, and LPr were associated to the co-occurrence of multiple SUDs. Motor disinhibition was the core dimension of SUDs. Cognitive disinhibition and Impulsive decision-making were also associated to SUDs. Self-report and neuropsychological dimensions of impulsivity were not correlated within the clinical group. HCs showed significant associations among these domains of impulsivity. Impulsivity should be viewed as a complex system of personality traits and neuropsychological processes among individuals with SUDs.

Brain response in heavy drinkers during cross-commodity alcohol and money discounting with potentially real rewards: A preliminary study

Background

Alcohol use disorder (AUD) is associated with exaggerated preference for immediate rewards, a candidate endophenotype for use disorders. Addiction symptomology is often well-described by the preference for immediate intoxication over other delayed prosocial rewards. We measured brain activation in AUD-implicated regions during a cross-commodity delay discounting (CCD) task with choices for immediate alcohol and delayed money.

Methods

Heavy drinkers (n=24) experienced a brief intravenous alcohol infusion prime, regained sobriety, then chose between 'One Shot' and delayed money in an adjusting delay CCD task (sober and intoxicated); also during fMRI (sober). Participants also performed a behavioral sensation seeking task and completed self-report inventories of other risk factors. We assessed brain activation to choices representing immediate intoxication versus delayed money rewards in a priori regions of interest defined within the framework of Addictions NeuroImaging Assessment.

Results

Activation to CCD choice versus control trials activated paralimbic and ventral frontal cortical regions, including orbital and medial prefrontal cortex, posterior cingulate/retrosplenial cortex, angular and superior frontal gyri. We detected no differences between immediate or delayed choices. Left medial orbitofrontal cortex activation correlated with alcohol-induced wanting for alcohol; females showed greater activation than males. Behavioral sensation seeking correlated with right nucleus accumbens task engagement.

Conclusions

Alcohol decision-making elicited activation in regions governing reward, introspection, and executive decision-making in heavy drinkers, demonstrating the utility of laboratory tasks designed to better model real-world choice. Our findings suggest that the brain processes subserving immediate and delayed choices are mostly overlapping, even with varied commodities.

The Initial Efficacy of Stand-Alone DBT Skills Training for Treating Impulsivity Among Individuals With Alcohol and Other Substance Use Disorders

Impulsivity is considered a core feature of substance use disorders (SUDs), including personological (i.e., negative urgency, positive urgency, lack of premeditation) and neuropsychological (i.e., cognitive and motor disinhibition, impulsive choice) dimensions. Dialectical Behavior Therapy Skills Training (DBT-ST) as a stand-alone treatment is an effective intervention for alcohol use disorder (AUD) and other SUDs. However, there are no studies that have investigated changes in impulsivity levels during a DBT-ST program, especially testing the therapeutic effects of DBT skills. Twenty-nine patients with AUD and other SUDs were admitted to a 3-month DBT-ST program. Self-report (i.e., UPPS-P) and computerized neuropsychological (i.e., Attentional Network test; Go/No-Go task; Iowa Gambling Task) measures of impulsivity were administered at the beginning and end of the DBT-ST. Distress tolerance (DTS), mindfulness (MAAS, FFMQ) and emotion regulation (DERS) were also assessed pre- and post-intervention. The study included two age- and gender-matched control groups: (a) untreated patients with SUDs (N = 29); (b) healthy controls (HCs) (N = 29). Twenty-four (82.7%) patients concluded the DBT-ST program. Emotion-based forms of impulsivity significantly improved during the program. At the end of treatment, impulsivity levels were significantly lower than those of untreated patients with SUDs and they were not significantly different from HCs. Cognitive disinhibition significantly decreased during the treatment. The improvement in impulsivity was explained by pre- posttreatment changes in distress tolerance, mindfulness and emotion regulation. Motor disinhibition did not improve during the treatment. These findings supported the initial efficacy of the DBT-ST program for addressing different features of impulsivity among individuals with AUD and other SUDs. Future follow-up studies should demonstrate the role of impulsivity domains in long-term relapse prevention.

Measurement and Functional Equivalence of a Reduced Version of the UPPS Impulsivity Scale Among Hispanic, Non-Hispanic Black, and Non-Hispanic White Adolescents

The current study aimed to assess the measurement equivalence and functional equivalence of the UPPS (Urgency, Premeditation, Perseverance, Sensation Seeking) Impulsivity Scale among three ethnoracial adolescent samples in the U.S. seventh-grade students who self-identified as Hispanic (n = 472), non-Hispanic Black (n = 89), or non-Hispanic White (n = 90), and completed an English-language version of the Child version of the UPPS, which was shortened and modified to include positive urgency items. Through a series of confirmatory factor analyses, the UPPS demonstrated configural, metric, and partial threshold invariance. Fisher's r-to-z transformations were used to assess the functional equivalence of the UPPS against well-validated measures of self-regulation and mental health commonly associated with impulsivity. We found some group differences in the magnitude of associations. Yet, overall, this study provides evidence that the UPPS can be used to measure distinct factors of impulsivity among Hispanic, non-Hispanic Black, and non-Hispanic White adolescents.

Predictors of polysubstance use in patients with severe alcohol use disorder: the role of reward craving

BACKGROUND

Different craving typologies (i.e., reward, relief, obsessive) have been identified in alcohol use disorder (AUD) but have been less investigated in specific populations like AUD patients with polysubstance use (PSU). The role of dysfunctional personality traits and reward pathways has been reported in both AUD and PSU. We hypothesized that patients with AUD-PSU might show a prevalent reward craving, alongside specific sociodemographic, clinical, and personality features, and aimed at investigating differences in 423 severe AUD outpatients with and without PSU.

METHODS

One hundred fifteen patients (27.1% of the sample, 67% males, 42 ± 11.6 years old) displayed PSU. Sociodemographic, clinical features and psychopathological/personality dimensions were assessed through: Craving Typologies Questionnaire (CTQ); Obsessive-Compulsive Drinking Scale (OCDS); UPPS-P Impulsive Behavior Scale (S-UPPS-P); Difficulties in Emotion Regulation Scale (DERS). A binomial logistic regression explored factors associated with PSU.

RESULTS

We found higher CTQ 'reward' scores (p < 0.001) in AUD-PSU patients, and a significant association between reward craving and PSU through logistic regression (OR:1.13; p = 0.005). Earlier AUD onset (p < 0.001), greater rates of binge drinking (p = 0.029), more legal problems (p = 0.015), but no significantly higher S-UPPS-S and DERS scores, were detected in AUD-PSU patients.

CONCLUSIONS

Reward craving was associated with increased risk for PSU in severe AUD patients. Given AUD-PSU participants greater severity and detrimental treatment responses imputed to PSU, identifying prevalent craving types among risk factors for PSU in AUD may help to implement therapeutic strategies. Addressing neurobiological and behavioral mechanisms through combined psychotherapies, pharmacological and neuromodulation treatments could support tailored interventions with better long-term outcome.

Impulsivity and Reactive-Proactive Aggression as Mechanisms of Alcohol-Related Sexual Intimate Partner Violence Perpetration among Romantic Partners

Background: Sexual intimate partner violence (S-IPV) commonly occurs within the contexts of committed romantic relationshops. Prior research has demonstrated the existence of a robust link between alcohol use and S-IPV. Despite this, few research studies have explored the etiological underpinnings of alcohol-related S-IPV perpetration, specifically. The present study examines the role of several key factors (i.e., problematic drinking, negative and positive urgency, proactive and reactive aggression) on S-IPV perpetration. Methods: Participants were 337 heavy drinking men and women in intimate relatinships who reported perpetrating some form of IPV toward their current partner within the past-year. A moderated-mediation model was used to determine how the key study variables interacted to predict S-IPV perpetration. Results: Results indicated that problematic drinking was positively correlated with both negative urgency and positive uregency. Findings also revealed that negative urgency, positive urgency, proactive aggression, and reactive aggression were all positively related to S-IPV perpetration. The indirect relationship between problematic drinking and S-IPV perpetration was mediated by positive urgency. Additionally, a significant main effect of proactive aggression on S-IPV perpetration was also detected. Conclusions: These findings suggest that impulsivity, specifically positive urgency, and proactive aggression may be under-appreciated constructs within the existing sexual aggression literature, and future research examining these variables as mechanisms explaining the association between the alcohol and S-IPV is warranted.

The association of alcohol use and positive and negative urgency to same day objective binge eating in emerging adults

Introduction

Objective binge eating and problematic alcohol use often co-occur and are common behaviors in emerging adults. Both behaviors are thought to be driven by affect regulation processes. Objective binge eating often occurs in the context of increasing or acute negative affect, and often occurs in solitude. Alcohol use in emerging adults can also be associated with negative affect regulation. However, in contrast to objective binge eating, a large body of research indicates that there are positively valenced pathways to alcohol use in this age group. Emerging adults often drink socially, to enhance enjoyment, and in the context of positive mood. We propose that one pathway to objective binge eating in this developmental period is through alcohol use itself, such that emerging adults who consume alcohol and who are more likely to act impulsively in the context of positive emotion (i.e., have high levels of positive urgency) may be more likely to binge eat following drinking.

Methods

We collected data using ecological momentary assessment in 106 undergraduates on positive and negative affect, motives for drinking and eating, and alcohol use and objective binge eating, in addition to baseline questionnaires of impulsivity.

Results

There were no significant changes in affect prior to drinking in this sample. Alcohol use at one time point significantly increased odds of objective binge eating at a later time point in the same day. Individual differences in positive urgency, the tendency to act rashly while experiencing positive affect, were also associated with increased odds of objective binge eating that occurred after alcohol use. Individual differences in negative urgency, the tendency to act rashly after experiencing negative affect, did not have a main effect on objective binge episodes, but did interact with alcohol use to increase the odds of objective binge eating following drinking. The vast majority of drinking episodes prior to objective binge eating were social drinking episodes, and participants most commonly endorsed "to have fun" as a reason for drinking.

Discussion

Results suggest that alcohol consumption may increase risk for objective binge eating in emerging adults.

Mediated and moderated associations between cumulative lifetime stressor exposure, emotional dysregulation, impulsivity, and lifetime alcohol use: A cross-sectional scoping study of UK drinkers

Stress, trait impulsivity, and emotional dysregulation are independent predictors of alcohol use and misuse, but little is known about the potential mechanisms that link these risk factors together. To address this issue, we carried out an exploratory cross-sectional study, on UK-based participants. Our preregistered, hypothesised theoretical framework was that emotional dysregulation mediates the association between cumulative lifetime stressor exposure and lifetime alcohol use. We also hypothesised that heightened impulsivity would strengthen these relations. As hypothesised, emotional dysregulation fully mediated the relation between cumulative lifetime stressor exposure and lifetime alcohol use. Several facets of impulsivity moderated these associations. For example, as levels of negative urgency increased, the associations between cumulative lifetime stressor exposure and emotional dysregulation, emotional dysregulation and lifetime alcohol use, and lifetime stress exposure and lifetime alcohol use, via emotional dysregulation, strengthened. These preliminary findings propose a theoretically framed model which integrates several prominent risk-factors for alcohol misuse, extending prior research and generating interesting and novel lines of enquiry for longitudinal and cross-cultural analyses. The findings also highlight the potential clinical utility of screening for lifetime stress exposure while tailoring personalised treatment interventions.

Drinking to Cope Mediates the Association between Dyadic Conflict and Drinking Behavior: A Study of Romantic Couples during the COVID-19 Pandemic

The COVID-19 pandemic spurred public health measures to reduce viral spread. Concurrently, increases in alcohol consumption and conflict in romantic partnerships were observed. Pre-pandemic research demonstrated a bidirectional association between couples' conflict and drinking. Recent research shows one's drinking motives (proximal predictors of drinking behavior) can influence another person's drinking in close relationships. It is possible that individuals are drinking to cope with distress following romantic conflict. The current study examined 348 cohabitating couples during the first lockdown in the spring of 2020. Our analyses examined coping motives as a mediator between dyadic conflict and drinking behavior using actor-partner interdependence models. Results showed that conflict was associated with greater reports of own drinking in gendered (distinguishable) and nongendered (indistinguishable) analyses through coping motives. Further, in mixed-gender couples, men partners' coping motives predicted less drinking in women, while women partners' coping motives predicted marginally more drinking in men. Partner effects may have been observed due to the increased romantic partner influence during the COVID-19 lockdown. While these results suggest that men's coping motives may be protective against women's drinking, more concerning possibilities are discussed. The importance of considering dyadic influences on drinking is highlighted; clinical and policy implications are identified.

Theoretical Frameworks and Mechanistic Aspects of Alcohol Addiction: Alcohol Addiction as a Reward Deficit/Stress Surfeit Disorder

Alcohol use disorder (AUD) can be defined by a compulsion to seek and take alcohol, the loss of control in limiting intake, and the emergence of a negative emotional state when access to alcohol is prevented. Alcohol use disorder impacts multiple motivational mechanisms and can be conceptualized as a disorder that includes a progression from impulsivity (positive reinforcement) to compulsivity (negative reinforcement). Compulsive drug seeking that is associated with AUD can be derived from multiple neuroadaptations, but the thesis argued herein is that a key component involves the construct of negative reinforcement. Negative reinforcement is defined as drug taking that alleviates a negative emotional state. The negative emotional state that drives such negative reinforcement is hypothesized to derive from the dysregulation of specific neurochemical elements that are involved in reward and stress within basal forebrain structures that involve the ventral striatum and extended amygdala, respectively. Specific neurochemical elements in these structures include decreases in reward neurotransmission (e.g., decreases in dopamine and opioid peptide function in the ventral striatum) and the recruitment of brain stress systems (e.g., corticotropin-releasing factor [CRF]) in the extended amygdala, which contributes to hyperkatifeia and greater alcohol intake that is associated with dependence. Glucocorticoids and mineralocorticoids may play a role in sensitizing the extended amygdala CRF system. Other components of brain stress systems in the extended amygdala that may contribute to the negative motivational state of withdrawal include norepinephrine in the bed nucleus of the stria terminalis, dynorphin in the nucleus accumbens, hypocretin and vasopressin in the central nucleus of the amygdala, and neuroimmune modulation. Decreases in the activity of neuropeptide Y, nociception, endocannabinoids, and oxytocin in the extended amygdala may also contribute to hyperkatifeia that is associated with alcohol withdrawal. Such dysregulation of emotional processing may also significantly contribute to pain that is associated with alcohol withdrawal and negative urgency (i.e., impulsivity that is associated with hyperkatifeia during hyperkatifeia). Thus, an overactive brain stress response system is hypothesized to be activated by acute excessive drug intake, to be sensitized during repeated withdrawal, to persist into protracted abstinence, and to contribute to the compulsivity of AUD. The combination of the loss of reward function and recruitment of brain stress systems provides a powerful neurochemical basis for a negative emotional state that is responsible for the negative reinforcement that at least partially drives the compulsivity of AUD.

Predicting Reasons for Drinking in a Dually-Diagnosed Sample with PTSD and Substance Use Disorders

Objective: Using the negative reinforcement and common factors frameworks, this work assessed whether and how anxiety sensitivity, distress tolerance, and impulsivity relate to reasons for drinking (RFD) in a residential treatment sample with co-occurring alcohol use disorder and posttraumatic stress disorder (AUD-PTSD). Demographic differences were also examined. Method: Participants were 75 (52.0% male, 78.7% white) adults at a residential substance use treatment facility who met criteria for AUD-PTSD with 98.67% meeting criteria for one or more substance use disorders in addition to AUD. Participants completed measures of anxiety sensitivity, distress tolerance, impulsivity, RFD, and AUD-PTSD symptoms. Univariate and multivariate linear regression was used with and without controlling for demographic variables (i.e., age, race, and sex). Results: The positive and negative urgency facets of impulsivity were positively related to both negative affect and cue/craving response RFD with relations maintained after controlling for demographic variables and including PTSD symptom severity (βs .30-.51). There were no significant relations between impulsivity and social RFD. No facets of anxiety sensitivity or distress tolerance were significantly related to RFD domains. Conclusions: Findings suggest that the urgency facets of impulsivity are crucial in understanding negative affect and cue/craving RFD. However, anxiety sensitivity and distress tolerance are not related to RFD in this dually diagnosed AUD-PTSD sample. Treatment considerations and future directions are discussed.

Examining the role of urgency in predicting binge size in bulimia nervosa

Greater binge size within bulimia nervosa is associated with elevated distress and impairment. Theoretical models posit that emotion dysregulation predicts binge eating, but little research has investigated the potential for dispositional traits that reflect difficulty in emotion regulation to predict binge size among women with bulimia nervosa. Research supports that negative urgency, the tendency to act rashly when feeling distressed, is associated with binge eating behavior among individuals with bulimia nervosa. Relatively fewer studies have explored associations between binge eating and positive urgency, the tendency to act rashly when feeling extreme positive affect. The urgency traits may predict greater binge size within bulimia nervosa. The current study sought to examine negative urgency and positive urgency as predictors of test meal intake in a sample of 50 women, n = 21 with bulimia nervosa and n = 29 healthy controls. Dispositional levels of positive urgency, negative urgency, positive affect, and negative affect were measured prior to a laboratory binge eating paradigm. Participants in the bulimia nervosa group scored higher on negative urgency, positive urgency, and negative affect than participants in the control group. Across participants, lower levels of negative affect were associated with greater test meal intake. Elevated levels of positive urgency predicted significantly greater test meal intake, but only for participants with bulimia nervosa. No other dispositional traits predicted test meal intake when the interaction of positive urgency and group was included in the model. Findings suggest positive urgency is an underappreciated, but potentially important, risk factor for greater binge size in bulimia nervosa.

Family History and Alcohol Use Outcomes: Examining Transmission of Risk through Impulsivity and the Moderating Role of Organized Sports Participation

BACKGROUND

College students are at risk for alcohol misuse and those who participate in organized sports are at even higher risk. Family history of alcohol problems (FH) and impulsivity are well-documented risk factors for alcohol use outcomes, but no research has examined the role of organized sports participation in moderating these associations. This study examined the associations between FH, alcohol consumption and alcohol use disorder (AUD) symptoms, the role of UPPS-P (Urgency, Premeditation, Perseverance, Sensation Seeking, Positive Urgency impulsive behavior scale) impulsivity dimensions in mediating the association between FH and alcohol use outcomes, and whether these associations vary by students' organized sports participation.

METHOD

Participants (N = 3,959, 64.7% female, 51.8% White; Mean age = 18.48 years, SD = .40) were recruited from a large, public university and completed an online survey in the fall and spring semesters of their first year in college. Path analyses were conducted in Mplus.

RESULTS

FH was associated with higher levels of alcohol consumption and more AUD symptoms. Lack of premeditation, lack of perseverance, and negative urgency partially mediated the associations between FH and alcohol consumption and AUD symptoms. The association between negative urgency and AUD symptoms was stronger for organized sports participants.

CONCLUSIONS

Impulsivity dimensions are risk factors for both alcohol consumption and AUD symptoms and serve as important pathways for the transmission of risk between generations. Prevention and intervention efforts aimed at reducing problematic alcohol use should target impulsivity generally, and particularly negative urgency among college students who participate in organized sports.

CADM2 is implicated in impulsive personality and numerous other traits by genome- and phenome-wide association studies in humans and mice

Impulsivity is a multidimensional heritable phenotype that broadly refers to the tendency to act prematurely and is associated with multiple forms of psychopathology, including substance use disorders. We performed genome-wide association studies (GWAS) of eight impulsive personality traits from the Barratt Impulsiveness Scale and the short UPPS-P Impulsive Personality Scale (N = 123,509-133,517 23andMe research participants of European ancestry), and a measure of Drug Experimentation (N = 130,684). Because these GWAS implicated the gene CADM2, we next performed single-SNP phenome-wide studies (PheWAS) of several of the implicated variants in CADM2 in a multi-ancestral 23andMe cohort (N = 3,229,317, European; N = 579,623, Latin American; N = 199,663, African American). Finally, we produced Cadm2 mutant mice and used them to perform a Mouse-PheWAS ("MouseWAS") by testing them with a battery of relevant behavioral tasks. In humans, impulsive personality traits showed modest chip-heritability (~6-11%), and moderate genetic correlations (rg = 0.20-0.50) with other personality traits, and various psychiatric and medical traits. We identified significant associations proximal to genes such as TCF4 and PTPRF, and also identified nominal associations proximal to DRD2 and CRHR1. PheWAS for CADM2 variants identified associations with 378 traits in European participants, and 47 traits in Latin American participants, replicating associations with risky behaviors, cognition and BMI, and revealing novel associations including allergies, anxiety, irritable bowel syndrome, and migraine. Our MouseWAS recapitulated some of the associations found in humans, including impulsivity, cognition, and BMI. Our results further delineate the role of CADM2 in impulsivity and numerous other psychiatric and somatic traits across ancestries and species.

Multilevel longitudinal relations among impulsive traits, positive expectancies, and binge drinking from late adolescence to adulthood: A developmental test of acquired preparedness

BACKGROUND

The Acquired Preparedness Model (APM) posits that highly impulsive individuals develop stronger positive alcohol expectancies, which in turn predicts heavier drinking. However, most acquired preparedness studies have focused solely on between-person relations, despite the theory suggesting that there are potential developmental-specific within-person relations. Thus, the current study tested the APM from late adolescence into adulthood, while disaggregating within- from between-person relations.

METHODS

Data come from a multigenerational study of familial alcohol use disorder (N=653) spanning three waves 5 years apart. Participants reported their lack of conscientiousness, sensation seeking, positive alcohol expectancies, and binge drinking at each wave. First, missing data techniques were used to create a "ghost timepoint," allowing the specification of four developmental-specific timepoints representing late adolescence (age 18 to 20), emerging adulthood (age 21 to 25), young adulthood (age 26 to 29), and adulthood (age 30 to 39). Second, a Random-Intercept Cross-Lagged Panel Model tested between-person and within-person relations among variables.

RESULTS

At the between-person level, lower conscientiousness and sensation seeking were correlated with higher positive expectancies, and positive expectancies were correlated with more binge drinking. There were no within-person prospective relations among conscientiousness, sensation seeking, and positive expectancies. However, within-person increases in lack of conscientiousness during late adolescence predicted within-person increases in emerging adult binge drinking, and within-person increases in late adolescent and emerging adult binge drinking predicted within-person increases in lack of conscientiousness during emerging and young adulthood, respectively. Similarly, within-person increases in late adolescent and young adult sensation seeking predicted within-person increases in binge drinking during emerging adulthood and adulthood, respectively. Binge drinking did not reciprocally predict sensation seeking.

CONCLUSIONS

Findings suggest that acquired preparedness effects may be between persons rather than within persons. However, several within-person developmental-specific relations among conscientiousness, sensation seeking, and binge drinking were observed, outside of expectancies. Findings are discussed in terms of theory and prevention.

Metacognition and insight dynamics exploration in borderline personality disorder: Exploring the underlying dynamics

Metacognition and Insight are related to hard-to-treat disorders and among them is Borderline Personality Disorder (BPD). We recruited 190 BPD patients and measured Insight, Metacognition, Impulsivity, and BPD traits. Results showed BPD's significant links with Insight and Metacognition. Metacognition significantly correlated with two Impulsivity dimensions, whereas Insight significantly correlated with most of them. Regressions analysis revealed a significant relationship between Insight and Metacognition on Impulsivity and Borderline traits. Mediation analysis proved the indirect effect of Metacognition/Insight on Borderline traits through Impulsivity at a significative level. Both seem relevant for research and therapeutic application in BPD following different dynamics even if the limitation of our study stands in its gender ratio and possible comorbidity issues. Urgency appears as a critical factor to assess, notably with Positive emotion-based impulsivity.

Alcohol-induced changes in mesostriatal resting-state functional connectivity are linked to sensation seeking in young adults

BACKGROUND

Studies in animals and humans suggest that greater levels of sensation seeking and alcohol use are related to individual differences in drug-induced dopamine release. However, it remains unclear whether drug-induced alterations in the functional synchrony between mesostriatal regions are related to sensation seeking and alcohol use.

METHODS

In this within-subject masked-design study, 21-year-old participants (n = 34) underwent functional magnetic resonance imaging to measure ventral tegmental area (VTA) resting-state functional connectivity to the striatum after receiving alcohol (target blood alcohol concentration 0.08 g/dL) or placebo. Participants also completed the UPPS-P Impulsive Behavior Scale to assess sensation seeking, the Young Adult Alcohol Consequences Questionnaire, and self-reported patterns of alcohol and drug use.

RESULTS

Voxel-wise analyses within the striatum demonstrated that during the alcohol condition (compared with placebo) young adults had less connectivity between the VTA and bilateral caudate (p < 0.05 corrected). However, young adults exhibiting smaller alcohol-induced decreases or increases in VTA-left caudate connectivity reported greater sensation seeking.

CONCLUSION

These findings provide novel information about how acute alcohol impacts resting-state connectivity, an effect that may be driven by the complex pre and postsynaptic effects of alcohol on various neurotransmitters including dopamine. Further, alcohol-induced differences in VTA connectivity represent a plausible mechanistic substrate underlying sensation seeking.
