Depressive symptoms, negative urgency and substance use initiation in adolescents

Positive and Negative Pathways Linking Depressive Symptoms to Problematic Alcohol Use Among Argentinian College Students: An Examination of Positive and Negative Urgency Traits and Internal Drinking Motives

Growing evidence suggests the tendency to act rashly under positive and negative emotions and affect-related drinking motives connect symptoms of mood disorders with alcohol-related problems. However, studies examining this sequence are scarce in Latin-American samples. The present study evaluated, in Argentinian college students (n = 403; 68.2% women; Mage = 21.03 ± 4.90), a sequential model of symptoms of depression, urgency traits, internal drinking motives, and problematic alcohol use. Path analysis was conducted to examine the direct and indirect associations between symptoms of depression and problematic alcohol use (heavy episodic drinking and alcohol-related negative consequences) via positive and negative urgency traits and internal drinking motives. Findings revealed indirect associations from depressive symptoms to problematic alcohol use via urgency traits and drinking motives (e.g. depression symptoms→positive [negative] urgency→enhancement [coping]→drinking problems). This suggests that students who experience more symptoms of depression may be more likely to react to these experiences of negative affect by engaging in heavy drinking episodes and encounter more alcohol-related problems. This seems to stem from a higher propensity to act rashly during intense emotional experiences and a greater motivation to drink as a means of regulating their mood. Future interventions aimed at preventing or reducing problematic alcohol use (especially among Argentinian young adults) might consider targeting these specific impulsivity traits as well as affect-related drinking motivations.

Adolescent depressive symptoms and memory performance in young adulthood: Testing critical period, accumulation, and pathway models using a sibling comparison design

RATIONALE

Despite the existing literature connecting depressive symptoms with cognitive function in adulthood, there is limited knowledge about the longitudinal association between depressive symptoms in adolescence and memory function in adulthood, as well as the mechanisms underlying this relationship.

OBJECTIVES

This study aims to determine whether depressive symptoms in adolescence are associated with memory function in young adulthood. To explore the underlying mechanisms of this association, it employs a life course approach, testing the critical period, accumulation, and pathway models.

METHODS

Utilizing data from the sibling sample of the National Longitudinal Study of Adolescent to Adult Health (Add Health), this study employed sibling fixed effects models to control for unobserved heterogeneity at the family level. To test various life course models, the analysis incorporated adult depressive symptoms, as well as an array of behavioral, psychosocial, and educational mechanism variables.

RESULTS

Sibling fixed effects estimates indicated a longitudinal association between depressive symptoms in adolescence and memory function in young adulthood (b = -0.084, p < 0.01). Depressive symptoms in adulthood neither explained nor intensified this association. Mediation analysis revealed that educational attainment modestly accounted for about 11% of the relationship between adolescent depressive symptoms and adult memory function. Combined, these findings lend support to the life course approach, with a specific focus on the critical period model.

CONCLUSIONS

This study's findings suggest that depressive symptoms in adolescence are an independent risk factor for memory function in adulthood. The empirical support for the critical period model underscores the importance of implementing early intervention programs and targeted strategies to support adolescents experiencing depressive symptoms.

Association of impulsive behavior and cerebrospinal fluid/plasma oxidation and antioxidation ratio in Chinese men

OBJECTIVES

Impulsive behavior is the precursor of many psychiatric and neurological conditions. High levels of impulsive behavior will increase health risk behavior and related injuries. Impulsive behavior is produced and regulated by central and peripheral biological factors, and oxidative stress (OS) can aggravate it. However, previous studies only showed that impulsive behavior was related to the level of the peripheral OS. Therefore, this study aims to clarify the relationship between OS and impulsive behavior in the brain and peripheral blood.

METHODS

We recruited 64 Chinese men. We measured superoxide dismutase (SOD) (including copper, zinc and manganese) and nitric oxide synthase (NOS) (including total, inducible and constitutive) in cerebrospinal fluid (CSF) and plasma. The Barratt Impulsiveness Scale version 11 (BIS-11) was used to evaluate impulsive behavior. The relationship between OS and impulsive behavior was evaluated by partial correlation analysis and stepwise multiple regression analysis.

RESULTS

Partial correlation analysis showed that the ratio of total NOS-to-MnSOD and iNOS-to-MnSOD in CSF were negatively correlated with the BIS-11 motor scores (r = -0.431, p = -0.001; r = -0.434, p = -0.001). Stepwise multiple regression analysis showed that the ratio of CSF iNOS-to-MnSOD was the most influential variable on the BIS-11 motor scores(β = -0.434, t = -3.433, 95 %CI(-0.374, -0.098), p = 0.001).

CONCLUSIONS AND RELEVANCE

The imbalance of central oxidation and antioxidation is related to impulsive behavior, which broadens our understanding of the correlation between impulsive behavior and OS.

Associations of DHEA(S) with negative and positive affect in people who smoke daily with elevated and low depression symptoms: A pilot laboratory study

BACKGROUND

Individuals with depression symptoms have a harder time quitting smoking. High negative affect and low positive affect are core depression symptoms and arise following cigarette abstinence. Investigating associations of biological markers with negative and positive affect may provide valuable information about factors relevant to smoking cessation in individuals with elevated depression symptoms.

METHODS

Depression symptoms were measured at a baseline session. Participants then completed two counterbalanced experimental sessions (non-abstinent, abstinent) and completed measures of positive and negative affect, and provided saliva samples. Saliva samples were assayed at the Salimetrics' SalivaLab (Carlsbad, CA) using the Salimetrics Salivary Dehydroepiandrosterone (DHEA) Assay Kit (Cat. No. 1-1202) and Dehydroepiandrosterone-sulfate (DHEA-S) Assay Kit (Cat. No. 1-1252).

RESULTS

There were no main or interactive associations of DHEA with negative affect. However, there were significant DHEAS × experimental session and DHEAS × experimental session × depression symptom level interactions with negative affect. In the high depression symptom group, DHEAS positively associated with negative affect during the non-abstinent experimental session, but DHEAS negatively associated with negative affect during the abstinent experimental session. There were no associations of DHEA or DHEAS with positive affect.

CONCLUSION

This study found that DHEAS negatively associated with negative affect during cigarette abstinence in individuals with elevated depression symptoms. This is important as high negative affect during cigarette abstinence may result in a return to smoking.

The trade-offs of co-ruminating with friends: A profile analysis

Adolescents' co-ruminating with friends has been tied to trade-offs: having higher quality friendships but experiencing more depressive symptoms. To determine if individual youth experience these trade-offs, we applied a person-centered approach to Swedish adolescents' self-reports of co-rumination with friends, depressive symptoms, and friend support (n = 2767, aged 12-16, 52% girls; 88% Swedish). We found four latent profiles: Two high in co-rumination and two low. One high co-rumination profile exhibited the proposed trade-offs; the other reported high friendship support and fewer depressive symptoms. Comparisons indicated that the trade-offs profile were primarily girls and exhibited comparatively more difficulties with stress regulation, conceptions of their parents and themselves, and relations with peers. Focusing on the complexity of co-rumination could reveal further nuances.

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.

Anxiety-specific associations with substance use: Evidence of a protective factor in adolescence and a risk factor in adulthood

Externalizing psychopathology is a strong risk factor for substance use, whereas the role of internalizing manifestations of distress, and anxiety in particular, in predicting substance use remains unclear. Studies have suggested that anxiety may be either a protective or risk factor for substance use. The present study aimed to clarify evidence for anxiety-specific associations with substance use, examining sex and developmental period (adolescence vs. adulthood) as potential moderators that may help explain conflicting results in the literature. In a longitudinal twin sample, cross-sectional associations of anxiety with substance use differed in adolescents and adults and in girls/women and boys/men. Controlling for externalizing psychopathology and depression, anxiety was associated with reduced substance use in adolescent girls and increased substance use in adult women. In contrast, anxiety-specific associations with substance use were not significant in boys and men. Possible explanations for these contrasting results across development and sex are discussed.

Validity and Reliability of a Revised S-UPPS-P Impulsive Behavior Scale: The Interplay between Impulsivity and Working Memory

Impulsivity is a multidimensional construct. The UPPS-P model of impulsivity differentiates five distinct dimensions: negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking. The present study, reports the first translation and validation of the recently revised short form of the UPPS-P scale (S-UPPS-P) on a Persian-speaking sample, examining the relationship between impulsivity and working memory. who also completed the Positive and Negative Affect Scale (PANAS), the Buss and Perry Aggression Questionnaire, the Behavioral Inhibition and Activation Scales (BIS/BAS), and the Wechsler Digit Span Task (WDST). A series of confirmatory factor analyses, and Cronbach's alpha results supported the factor structure of the scale. The findings supported the S-UPPS-P model's hypothesized correlations with PANAS, aggressiveness, and the construct validity of the model. The results of hierarchical regression analysis showed that backward and forward digit span scores of the WDST predicted the S-UPPS-P impulsivity scores over the portion explained by BIS/BAS, PANAS, and aggression scores. To conclude, the revised S-UPPS-P Impulsive Behavior Scale was well supported even in a very different population than usually sampled, adding to growing evidence that it assesses distinct but interrelated aspects of the impulsivity construct. Our findings also suggest that attentional capacities and working memory play important roles in the prediction of impulsivity.

Understanding treatment non-responders: A qualitative study of depressed adolescents' experiences of 'unsuccessful' psychotherapy

OBJECTIVES

This paper aimed to explore the experiences of depressed adolescents who completed but did not 'respond' to standard psychotherapy, based on a lack of improvement in pre-post symptoms scores.

DESIGN

This was a qualitative study employing interpretative phenomenological analysis (IPA).

METHOD

Seventy-seven adolescents with moderate to severe depression were interviewed as part of a qualitative arm of a randomised controlled trial. Five adolescents' post-treatment interviews were purposively sampled, based on lack of improvement on pre-post symptom scores, and adolescents still scoring above the clinical threshold for depression. The interviews were analysed using IPA.

RESULTS

Adolescents made sense of their depression as part of their identity and held negative expectations of therapy. Some aspects of therapy brought up intolerable feelings that contributed to disengagement in the therapeutic process and culminated in disappointing and hopeless endings. On the other hand, where a stronger therapeutic relationship was developed, some participants experienced certain improvements.

CONCLUSIONS

Findings highlight how actively exploring the adolescent's therapy expectations, developing a strong early therapeutic relationship and being mindful of the potential impact of endings are important in therapeutic work with adolescents with depression, especially where they may have a strong sense of hopelessness and self-criticism. Moreover, the finding that adolescents experienced improvements in other domains despite a lack of symptom reduction highlights the need to review how treatment outcomes are currently defined. Integrating individual perspectives of therapy with quantitative outcome measures can provide a more nuanced insight of treatment effects.

Religious affiliation protects against alcohol/substance use initiation: A prospective study among healthy adolescents

BACKGROUND

A substantial volume of the literature suggests that religious factors buffer against alcohol/substance use among adults, but research among adolescents is sparse. Further, few studies in this area have been prospective, and therefore it is unclear how religion may impact less alcohol/substance use among adolescents.

METHOD

We prospectively evaluated effects of religious affiliation on initiation of alcohol/substance use in a sample of 81 psychiatrically healthy 13-14-year-olds from New England, over a 3-year period (from November 2015 to January 2019). Known risk factors were also evaluated including anxiety, depression, and impulsivity; family history of mental illness and alcohol/substance misuse; and volume of brain regions implicated in adolescent alcohol/substance misuse (assessed by Magnetic Resonance Imaging).

RESULTS

Religiously affiliated adolescents were significantly less likely to initiate use of alcohol/substances (hazard ratio [HR] = 0.38). The addition of family history of alcohol/substance misuse to the model increased the predictive value of religious affiliation (HR = 0.34). Other risk factors did not diminish nor increase observed effects.

CONCLUSIONS

These findings support and extend the current research by suggesting that religious affiliation protects against initiation of alcohol/substance use during early adolescence, particularly in individuals with elevated risk.

The Genetically Informed Neurobiology of Addiction (GINA) model

Addictions are heritable and unfold dynamically across the lifespan. One prominent neurobiological theory proposes that substance-induced changes in neural circuitry promote the progression of addiction. Genome-wide association studies have begun to characterize the polygenic architecture undergirding addiction liability and revealed that genetic loci associated with risk can be divided into those associated with a general broad-spectrum liability to addiction and those associated with drug-specific addiction risk. In this Perspective, we integrate these genomic findings with our current understanding of the neurobiology of addiction to propose a new Genetically Informed Neurobiology of Addiction (GINA) model.

Recognizing Adolescent Depression with Parent- and Youth-Report Screens in Pediatric Primary Care

OBJECTIVES

To compare the use of the parent-report Pediatric Symptom Checklist (PSC-17P) and youth-report Patient Health Questionnaire-9 Modified for Teens (PHQ-9M) in compliance with recent quality standards for adolescent depression screening.

STUDY DESIGN

Parents of 5411 pediatric outpatients (11.0-17.9 years old) completed the PSC-17P, which contains scales that assign categorical risk for overall (PSC-17P-OVR), internalizing (PSC-17P-INT), externalizing (PSC-17P-EXT), and attention (PSC-17P-ATT) problems. Adolescents completed the PHQ-9M, which assesses depressive symptoms. Both forms were completed online within 24 hours of each other before pediatric well-child visits.

RESULTS

A total of 9.9% of patients (n = 535) were at risk on the PSC-17P-OVR, 14.3% (n = 775) were at risk on the PSC-17P-INT, and 17.0% (n = 992) were at risk on either or both scales (PSC-17P-OVR and/or PSC-17P-INT). Using the PHQ-9M cut-off score of 10 (moderate-very severe depression), an additional 2.4% (n = 131) were classified as at risk, with 66.8% (n = 263) of all PHQ-9M positives (n = 394) also coded as at risk by the PSC-17P-OVR and/or PSC-17P-INT scales. Using a PHQ-9M cut-off score of 15 (severe-very severe depression), only 29 patients (21.8% of the PHQ-9M positives) not identified by the PSC-17P-OVR and/or PSC-17P-INT were classified as being at risk.

CONCLUSIONS

The combined PSC-17P-OVR and/or PSC-17P-INT scales identified 17% of adolescents as at risk for depression, including about two-thirds to three-quarters of adolescents classified as at risk on the PHQ-9M. These findings support using the PSC-17P to meet quality standards for depression as well as overall screening in pediatrics. Primary care clinicians can add the PHQ-9M to identify additional adolescents who may self-report depressive symptoms.

The role of affective urgency and emotion regulation in vaping susceptibility

•

Both positive and negative urgency are correlated with emotion dysregulation.

•

Emotion dysregulation mediated the effect of negative urgency but not positive urgency on a measure of vaping susceptibility.

•

Measures to prevent e-cigarette use should target individuals with high negative urgency and focus on building emotion regulation skills.

Introduction

The prevalence of E-cigarette use is increasing along with concerns about the negative health effects of their use. Understanding the psychological constructs associated with susceptibility to beginning regular e-cigarette use may be helpful for prevention efforts. Factors such as emotion regulation (ER) and impulsivity, specifically urgency, have been significantly correlated with patterns of drug addiction in the past. With few prior studies linking ER and impulsivity factors with e-cigarette susceptibility, the present study aims to assess their relationship in predicting e-cigarette susceptibility in university never-smokers.

Method

Two hundred and twenty-five students were surveyed online using a questionnaire measuring difficulties in ER, impulsivity, and e-cigarette susceptibility. Path analysis was used to understand the relationship between positive and negative urgency and ER in predicting susceptibility to use.

Results

Results indicated that negative urgency was mediated by difficulties in ER to predict susceptibility while positive urgency was not significantly related to susceptibility.

Conclusion

The results of this study offer insights into the role affective traits contribute to susceptibility to e-cigarettes, potentially improving future addiction prevention research.

The role of family conflict in mediating impulsivity to early substance exposure among preteens

OBJECTIVES

Preadolescence substance exposure, which increases the risk of regular substance use, has been a public health concern. Although studies found that impulsivity is a predisposing factor of early substance exposure, the pathways through which impulsivity is associated with early substance exposure remain unclear. This study examined how family conflict mediates this association among U.S. preteens as family environment plays an essential role in pre-adolescent development.

METHODS

Respondents (N = 11,800, 9-10 years old) from the Adolescent Brain Cognitive Development (ABCD) Study Release 2.01 (July 2019) were included in this study. Generalized structural equation modeling was performed to investigate the mediation effects of family conflict on the associations between childhood impulsivity and early exposure to alcohol and tobacco use, controlling for covariates based on the Problem Behavior Theory.

RESULTS

Pre-adolescents with high impulsivity levels (≥90^th percentile) were more likely to report early alcohol and tobacco exposure (total effect: ORs = 1.49 and 1.70, respectively), where 4.13% and 12.41% of the associations, respectively, were meditated by family conflict (indirect effect: ORs = 1.02 and 1.07; Sobel test ps = 0.022 and 0.005, respectively).

CONCLUSIONS

Family conflict mediates the associations between childhood impulsivity and early substance exposure among preteens, with higher impulsivity leading to more severe family conflicts that are, in turn, associated with a higher likelihood of early substance exposure. To prevent preteens with high impulsivity level from early use of substances, interventions may focus on reducing family conflicts such as parenting counseling that guides parents to strengthen conflict-resolution skills and create a stable home environment for preteens.

How are depression and suicidal ideation associated with multiple health risk behaviours among adolescents? A secondary data analysis using the 2016 Korea Youth Risk Behavior Web-based Survey

WHAT IS KNOWN ON THE SUBJECT?: Adolescents who partake in one health risk behaviour (HRB) easily adopt other HRBs, simultaneously or subsequently. Multiple HRBs might threaten adolescents' future health in adulthood. Adolescents with psychological problems have higher rates of smoking, alcohol use, early sexual initiation and activity, and illicit substance use compared with others. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: A considerable number of Korean adolescents with mental health problems were engaged in multiple HRBs. For those with mental health problems, more than half of the Korean adolescents with multiple HRBs tended to use alcohol and cigarettes concurrently. Korean adolescents who felt depressed and had suicidal ideation were more likely to engage in a greater number of HRBs. Substance abuse is the most prevalent problem that is combined with other HRBs among those with depression and suicidal ideation compared to those who exhibited other HRBs. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: When mental health nurses working in schools and community centres for mental health identify Korean adolescents with significant depression and suicide ideation levels, they should also assess adolescents' engagement in multiple HRBs. Population-based campaigns and policy changes that emphasize both psychological health and risky behaviour reduction among adolescents should be provided simultaneously to students and school nurses. ABSTRACT: Introduction There is limited understanding about whether poor mental health is associated with certain combinations of multiple health risk behaviours (HRBs) such as smoking, drinking, early sexual activity and substance abuse. Aim To determine the prevalence of multiple HRBs and to identify associations between poor mental health and multiple HRBs as the number of HRBs increases. Methods This cross-sectional study was conducted using the 2016 Korea Youth Risk Behavior Web-based Survey (N = 65,528). Descriptive statistics and multinomial logistic regression analyses were conducted using the complex sample data. Results Overall, 28.6% and 13.9% of Korean adolescents were involved in one or multiple HRBs, respectively. Adolescents who were depressed (OR = 1.43-4.47, 95% CI = 1.37-1.49 to 3.23-6.20) and/or who had suicidal ideation (OR = 1.33-3.19, 95% CI = 1.25-1.42 to 2.25-4.51) were more likely to engage in multiple HRBs. Discussion A considerable numbers of Korean adolescents are engaged in multiple HRBs. When adolescents self-reported depression and suicidal ideation, they were more likely to engage in a greater number of HRBs than single HRB. Implications for practice Tailored interventions to decrease multiple HRBs should be designed and provided by considering adolescents' mental health status and needs.

CANUE: A Theoretical Model of Pain as an Antecedent for Substance Use

BACKGROUND

Pain and substance use are frequently comorbid and have been shown to exert bidirectional effects. Self-medication of pain and distress via substance use is common and can be understood via negative reinforcement, ultimately strengthening the pathway between pain to substance use over time. As such, a testable model of the potentially modifiable candidate mechanisms that underlie the pain to substance use pathway is needed.

PURPOSE

This review proposes a testable model of pain as an antecedent to substance use to guide future research and inform clinical practice.

METHODS

An integrative review of current evidence regarding pain, substance use, and associated risk factors (i.e., negative affect, pain-related attitudes, negative urgency, and substance use outcome expectancies) was conducted.

RESULTS

The Catastrophizing, Anxiety, Negative Urgency, and Expectancy (CANUE) model highlights modifiable risk factors for self-medicating pain with substance use, including increased negative affect and maladaptive pain-related attitudes (i.e., pain catastrophizing, pain anxiety, and fear of pain), negative urgency, and substance-related outcome expectancies for pain relief and enhanced pain coping.

CONCLUSIONS

Targeted behavioral and psychological interventions that address these factors may facilitate more adaptive pain-coping responses, thereby reducing the impacts of pain on substance use. Systematic research is needed to evaluate the validity and clinical utility of this model.

Early-life stress affects drug abuse susceptibility in adolescent rat model independently of depression vulnerability

The development of substance abuse problems occurs due to a diverse combination of risk factors. Among these risks, studies have reported depression and early-life stress as of importance. These two factors often occur simultaneously, however, there is a lack of understanding of how their combined effect may impact vulnerability to drug abuse in adolescence. The present study used rats with different vulnerability to depression (Wistar and Wistar-Kyoto) to investigate the impact of maternal separation (MS) on emotional state and drug addiction vulnerability during the adolescence period. Mothers and their litters were subjected to MS (180 min/day) from postnatal day 2 to 14. The offspring emotional state was assessed by observing their exploratory behavior. Drug abuse vulnerability was assessed through conditioning to cocaine. MS impacted the emotional state in both strains. Wistar responded with increased exploration, while Wistar-Kyoto increased anxiety-like behaviours. Despite the different coping strategies displayed by the two strains when challenged with the behavioural tests, drug conditioning was equally impacted by MS in both strains. Early-life stress appears to affect drug abuse vulnerability in adolescence independently of a depression background, suggesting emotional state as the main driving risk factor.

Longitudinal associations between negative urgency, symptoms of depression, cannabis and alcohol use in veterans

There is a high comorbidity between symptoms of depression and cannabis and alcohol use in civilian and veteran populations. Prospective studies attempting to clarify the directionality of these comorbidities have yielded mixed results. Further, the relations between these constructs and impulsive personality, particularly negative urgency (NU, the tendency to act rashly when experiencing emotional distress) warrants further attention, as NU relates to symptoms of depression and alcohol and cannabis use. Importantly, NU partially accounts for the association between symptoms of depression and cannabis and alcohol problems in cross-sectional studies. This study examined alternative theories of directionality in order to better understand the longitudinal associations between symptoms of depression, NU, and cannabis or alcohol use. Three semiannual waves of data (baseline, 6-month, and 12-month) were collected in parallel assessments from a sample of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans (N = 361). Autoregressive cross-lagged panel models were used to test four alternative theory-driven models about the longitudinal associations between the interaction of symptoms of depression and NU and cannabis or alcohol use. Models revealed unique direction of effects specific to each substance, such that the interaction between symptoms of depression and NU at 6 months postbaseline predicted more alcohol use at 12 months postbaseline, whereas more cannabis use at 6 months postbaseline predicted more severe symptoms of depression at 12 months postbaseline. Results suggests alternate directions of effect for cannabis and alcohol use. Future research should examine these patterns over wider assessment periods in order to see more variability and change over time. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Does prenatal cocaine exposure predict adolescent substance use?

Prenatal cocaine exposure (PCE) has rarely been examined as a predictor of substance use during late adolescence, and few studies have examined both the initiation of substance use and current substance use as outcomes. The present longitudinal study examined PCE, other prenatal exposures, and psychosocial risk factors for their association with substance use in mid to late adolescence. Adolescents (n = 150) followed since birth reported on their use of alcohol, cigarette, and cannabis every 6 months from age 15.0 to 17.5 using a computer-assisted self-administration version of the Youth Risk Behavior Survey. PCE did not predict substance use in a series of growth curve analyses. Several psychosocial risk factors were associated with adolescents' substance use. Having friends who use substances predicted past month cigarette and cannabis use as well as initiation of alcohol and cannabis use, while depressive symptoms predicted initiation of alcohol, cigarette, and cannabis use. The current findings suggest that more proximal psychosocial factors may play a greater role in adolescent substance use than prenatal substance exposure.

Risk of Disordered Eating Behaviors in Adolescents with Type 1 Diabetes

OBJECTIVE

Management of type 1 diabetes (T1D) may be difficult for adolescents, who often fail to meet glycemic targets. Adolescents are also at an increased risk for negative affect (i.e., anxiety, depressive symptoms) and are prone to disordered eating behaviors (DEB). This study hypothesized that negative affect would be associated with DEB, self-management, and glycemic control, but that this would be moderated by negative urgency (the urge to engage in impulsive behaviors in response to negative affect), such that this relationship would be significant only for those with higher negative urgency.

METHODS

The Eating in Adolescents with T1D Study recruited 100 caregiver-adolescent dyads (55% male youth, 48% Caucasian) to complete questionnaires reporting on the adolescent's negative affect, negative urgency, DEB, and diabetes management. Glycemic control 3-4 months following survey completion was extracted from the medical record.

RESULTS

A total of 61% of adolescents reported elevated symptoms of anxiety or depression and 25% reported elevated disordered eating symptoms. A total of 81% of adolescents had an A1c level above recommended targets. Negative affect was associated with DEB, suboptimal T1D self-management, and suboptimal glycemic outcomes, moderated by higher levels of negative urgency. Negative affect was associated directly with suboptimal self-management and glycemic control, but not DEB, at all levels of negative urgency.

CONCLUSIONS

Adolescents reported high levels of negative affect, DEB, and suboptimal glycemic control. Interventions that target negative affect and negative urgency in adolescents with T1D are needed in order to reduce the risk for DEB and negative diabetes health outcomes.

[The Association Between Illicit Drug Use, Borderline Personality Disorder and Depression in a Help-Seeking Sample of Adolescents]

The Association Between Illicit Drug Use, Borderline Personality Disorder and Depression in a Help-Seeking Sample of Adolescents Risk-taking behavior is a common phenomenon in adolescence. Even prevalence rates for illicit drug use are considerably high in youth and associated with a range of psychiatric disorders, especially depression and Borderline Personality Disorder (BPD). However, there is a lack of data investigating differences in psychopathology between different substance user groups. Therefore, aim of the study was to investigate occurrence of depression and BPD symptoms in different drug risk groups (no use vs. occasional use vs. frequent use). Further aim of the study was to examine risk profiles regarding single BPD criteria. Data of n = 347 adolescents (81.7 % female, mean age 14.95, SD = 1.50) presenting at the specialized outpatient clinic for risk-taking and self-harming behavior (AtR!Sk) in Heidelberg were analyzed. Results show that BPD is clearly associated with illicit drug use in adolescence. There is no difference between occasional and frequent users in terms of mean number of BPD criteria. However, frequent users differ from occasional users regarding greater number of impulsivity and anger criteria. After adjusting for sociodemographic variables there was no association between drug use and depression. Since even single events of illicit drug use are associated with higher levels of BPD, clinicians should rapidly target to stop consumption. Further, psychotherapeutic interventions for BPD in high-risk consumers should especially focus on facilitating adaptive emotion regulation skills in regards to impulsivity and anger.

Impulsive Responses to Positive and Negative Emotions: Parallel Neurocognitive Correlates and Their Implications

Theory about the conceptual basis of psychiatric disorders has long emphasized negative emotionality. More recent ideas emphasize roles for positive emotionality and impulsivity as well. This review examines impulsive responses to positive and negative emotions, which have been labeled as urgency. Urgency is conceptually and empirically distinct from other forms of impulsivity. A large body of work indicates that urgency is more robustly related to psychopathology than are other forms of impulsivity. Researchers have considered 4 neurocognitive models of urgency: excessive emotion generation, poor emotion regulation, risky decision making, and poor cognitive control. Little evidence supports emotion generation or risky decision making as the core issues driving urgency. Rather, urgency appears related to dysfunction in key hubs implicated in the integration of cognitive control and emotion regulation (e.g., the orbitofrontal cortex and anterior insula), expressed as response inhibition deficits that emerge most robustly in high arousal contexts. These neurocognitive processes appear remarkably parallel for positive and negative urgency. We provide methodological suggestions and theoretical hypotheses to guide future research.

Greater delay discounting and cannabis coping motives are associated with more frequent cannabis use in a large sample of adult cannabis users

BACKGROUND

Self-regulation deficits expressed through a decreased ability to value future rewards (delay discounting (DD)) and impaired emotion regulation (negative urgency (NU), cannabis coping motives (CCM), and anxiety sensitivity (AS)) relate to more frequent or problematic cannabis use. However, there is a need to better understand how self-regulation and emotion regulation constructs reflect competition between deliberative and reactive systems that drive individual differences in cannabis use patterns. Further, few studies assess frequency of cannabis use within and across days of use, which may obscure differentiation of individual differences.

METHODS

In a large national sample of 2545 cannabis users, Latent Class Analysis was used to derive participant sub-classes based on two frequency indices, self-reported cannabis use days and times cannabis was used per day. Three classes emerged: Low (1-9 days/month, 1 time/day; 23 %), moderate (10-29 days/month, 2-3 times/day; 41 %), and high (30 days/month, ≥4 times/day; 36 %). Relationships among frequency classes and emotional regulation and impulsivity were assessed with a multinomial logistic regression.

RESULTS

Higher frequency use was associated with greater DD (χ2 = 6.0, p = .05), greater CCM (χ2 = 73.3, p < .001), and lower cognitive AS (χ2 = 12.1, p = .002), when controlling for demographics, tobacco use, and number of cannabis administration methods. Frequency class and NU were not significantly associated.

CONCLUSIONS

Identifying meaningful patterns of cannabis use may improve our understanding of individual differences that increase risk of frequent or problematic cannabis use. Excessive delay discounting and using cannabis to cope with negative affect may be relevant targets for treatments designed to reduce cannabis use.

Problematic Internet Use, Non-Medical Use of Prescription Drugs, and Depressive Symptoms among Adolescents: A Large-Scale Study in China

This large-scale study aimed to test, among Chinese adolescents, the association between problematic Internet use (PIU), non-medical use of prescription drugs (NMUPD), and depressive symptoms, as well as the mediating effects of NMUPD on the associations above. This study used the data from the 2017 National School-based Chinese Adolescents Health Survey, and 24,345 students’ questionnaires qualified for the analyses. Generalized linear mixed models and path models were performed. In the models without mediation, PIU was associated with depressive symptoms (unstandardized β estimate = 0.26, 95% CI = 0.25–0.27); frequent use of opioid or sedative was also related to depressive symptoms (unstandardized β estimate for opioid = 2.77, 95% CI = 1.90–3.63; unstandardized β estimate for sedative = 4.45, 95% CI = 3.02–5.88). Additionally, the results of the path models indicated that opioid misuse partially mediated the association between PIU and depressive symptoms. PIU and opioid/sedative misuse were related to the increased risk of depressive symptoms, respectively. The association above might be complicated, and PIU may elevate the risk of opioid or sedative misuse and depressive symptoms, which in turn could worsen the situation of PIU and vice versa. Multidisciplinary health intervention programs to prevent adolescents involving in PIU, as well as NMPUD, are recommended to be provided.

Substance Use in Adolescents Presenting to the Emergency Department

Background:

Adolescent substance use is a dynamic public health problem. Adolescence is a unique developmental period involving overlapping biological, psychological, and social factors which increase the rates of initiation of substance use. The developing adolescent brain is particularly susceptible to the effects of substances and most adults with substance use disorders began to have symptoms and problems in their adolescent years. Yet, for various reasons, most adolescents who use, misuse, abuse, or are addicted to substances do not perceive the need for treatment.

Objective:

Drug and alcohol use among adolescents is a common presentation in hospital Emergency Departments (EDs) and presents in different forms including in association with intoxication, withdrawal states, or trauma associated with drug-related events. For many adolescents with substance use, the Emergency Department (ED) is the first point of contact with medical personnel and thus also serves as a potential entry point into treatment.

Methods:

This article reviews the common ways drug and alcohol problems present in the ED, clinical assessment of the patient and family, screening, laboratory testing, brief interventions in the ED, and referral to treatment beyond the ED.

Conclusion:

Guidelines on how to manage the shifting terrain of adolescent substance use presenting in EDs across the nation continue to evolve. We highlight that considerable further research is needed to inform effective ED protocols to address this important individual and public health safety concern. Systems of care models which include collaborative teams of diverse stake holders are needed to effectively manage adolescents with substance use disorders.

Anhedonia, screen time, and substance use in early adolescents: A longitudinal mediation analysis

INTRODUCTION

Screen time is associated with substance use risk among adolescents; however, less is known about the underlying factors that explain this association.

METHODS

This research examined anhedonia, a facet of depression noted by the reduced capacity to experience pleasure, as a mediating factor in the relationship between screen time (hours spent watching television, using internet, and/or playing video games outside of school) and substance use (alcohol and/or cigarettes). We used a longitudinal survey design among a sample of students aged 9-11 years in the 4th to 6th grades in Southern California, United States of America [N = 709 (354 males)].

RESULTS

Structural equation modeling (SEM) findings revealed longitudinal mediation effects of anhedonia on the association between screen time and substance use, while controlling for baseline screen time, baseline individual and peer substance use, race/ethnicity, and gender. Moderation analysis based on a multiple-group approach revealed that gender was not a significant moderator of this mediation pathway.

CONCLUSIONS

Adolescents may become desensitized and exhibit a blunted response to hedonic effects from increased screen time. This may result in increased anhedonia and greater risk for substance use through the need to compensate for the reduced experience of rewards. These findings have implications for future school-based substance use prevention and intervention programs.

UPPS-P impulsive personality traits and adolescent cigarette smoking: A meta-analysis

BACKGROUND

Adolescence is a critical developmental period in the trajectory of nicotine dependence, highlighting the need for a greater understanding of the modifiable risk factors. An extensive body of research has found that trait impulsivity is associated with higher levels of adolescent smoking; however, findings have been mixed. The present study aimed to synthesise existing literature to determine the strength and nature of the relationship between the UPPS-P impulsive traits and both adolescent cigarette consumption and nicotine dependence.

METHODS

Fifty-one studies were meta-analysed using a random effects model to determine the association between each UPPS-P impulsive trait and both adolescent cigarette consumption and nicotine dependence. Age, gender, ethnicity and sample type were examined as potential moderators.

RESULTS

Cigarette consumption was positively associated with each UPPS-P impulsive trait (r's ranging from 0.17-0.20). There were an insufficient number of studies to meta-analyse the association between nicotine dependence and the UPPS-P impulsive traits. There were no significant moderation effects of age, gender, ethnicity or sample type.

CONCLUSIONS

Findings suggest that each UPPS-P impulsive trait shares similar associations with adolescent cigarette consumption. Additional studies are needed to determine the relationship between adolescent nicotine dependence and impulsivity. As most adult smokers initiate during adolescence, targeting these impulsive traits via novel prevention and intervention strategies may assist in reducing the prevalence of smoking.

The relationship among depressive symptoms, urgency, and problematic alcohol and cannabis use in community adults

BACKGROUND

This study examined alternative models for how negative and positive urgency influence the relationship between depressive symptoms and alcohol and cannabis use in a community sample.

METHODS

Participants included adults (n = 675; age = 42.57, SD = 15.66; 65.0% female; 74.2% White) in the community sample from the Rockland Project by the Nathan Kline Institute. Path analyses were conducted.

RESULTS

Negative urgency was a unique mediator in the relationship between depressive symptoms and problematic alcohol use (β =0.121, 95% CI = 0.060-0.182) and problematic cannabis use (β =0.120, 95% CI = 0.060-0.179). Negative and positive urgency significantly moderated the relationship between depressive symptoms and problematic cannabis use (negative urgency: β = 0.092, 95% CI = 0.040-0.145; positive urgency: β = 0.070, 95% CI = 0.022-0.119), such that the relationship was positive at high levels and negative at low levels of urgency. The patterns and levels of the relationships between depressive symptoms and cannabis use differed between negative and positive urgency. Neither urgency trait moderated the relationship between depressive symptoms and problematic alcohol use.

CONCLUSIONS

Despite being strongly related, negative and positive urgency have distinct roles in the relationship between depressive symptoms and problematic alcohol and cannabis use. Previous finding with younger samples that do not include both traits in the model at time generalize and at other times do not replicate, which warrants the continued examination of how these traits impart risk across the lifespan.

Impulsivity facets and substance use initiation: A comparison of two models of impulsivity

Several types of impulsivity have been linked to various substance use outcomes. The UPPS-P framework has received major focus within the field of substance use research. However, this framework is not without limitation. An alternative framework is the Two-Factor Model of impulsivity, which posits that rash impulsivity and reward drive are the central, if not sufficient, domains of impulsivity. Unfortunately, the extant literature is quite limited in terms of work that have directly compared the UPPS-P framework to the Two-Factor Model of impulsivity, particularly in prospective designs focused on the initiation of common, problematic forms of substance use among adolescents (i.e., alcohol and marijuana use). In the current study, the UPPS-P measures were compared to dedicated measures of the Two-Factor Model of impulsivity in a sample of Chilean adolescents who were lifetime abstainers of alcohol or marijuana use at baseline (N = 541) to predict the initiation of use for these substances at a one-year follow-up. Results showed that the Two-Factor Model had superior predictive utility compared to the UPPS-P measures, and only rash impulsivity and reward drive were significant predictors in a multivariate model that simultaneously considered UPPS-P and Two-Factor Model assessments. Overall, the current findings indicate that the Two-Factor Model should be considered to index risk of substance use initiation to guide prevention efforts and highlight the importance of direct comparisons of alternative measurement and theoretical frameworks of impulsivity within the field of substance use research.

Impulsive reactivity to emotion and vulnerability to psychopathology

Impulsiveness has been studied as an aspect of personality and psychopathology for generations. There are longstanding disagreements about how to define it and whether it should be viewed as one construct or several. This article begins by briefly reviewing some earlier and some more recent work on impulsiveness. Several approaches have recently converged to focus on a distinction between impulsive reactions to emotion and impulsive properties that are not initiated by emotion. From this review, we turn to psychopathology. It is well known that impulsiveness is related to externalizing psychopathology, but some have concluded that a similar relation does not exist for internalizing psychopathology. A recent literature is described that challenges the latter conclusion, linking impulsive reactivity to emotion to both externalizing and internalizing aspects of psychopathology. Discussion then turns to emotion-related impulsiveness and other constructs to which it is conceptually and empirically related, reexamining whether other conceptual targets should be added to the discussion. The article closes with a consideration of how important it is to continue to remain open to new conceptual perspectives. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Perceived Discrimination and Substance Use among Adolescents: Examining the Moderating Effect of Distress Tolerance and Negative Urgency

BACKGROUND

Perceived discrimination has been found to increase substance use vulnerability among adolescent populations. However, less is known about individual level factors which may moderate this risk.

OBJECTIVES

The aim of the current study is to examine whether two emotion-based personality traits (i.e., distress tolerance and negative urgency) moderates the effect of perceived discrimination on substance use. We hypothesized that high distress tolerance would decrease risk, while high negative urgency would increase risk for substance use as a consequence of discrimination.

METHODS

108 youth ages 12-18 (68.6% male; 56.2% African-American) provided data on perceived discrimination, distress tolerance, negative urgency, and substance use (i.e., alcohol and marijuana use).

RESULTS

Contrary to our hypothesis, no moderating effect was observed for negative urgency. Distress tolerance was found to moderate the relationship, but in the opposite direction than expected.

CONCLUSIONS

It is speculated that this counterintuitive finding may be due to the racial/ethnic composition of the sample, suggesting that distress tolerance may operate differently among minority youth. Further research examining these relationships among minority youth is warranted.

Peer Victimization, Supportive Parenting, and Depression Among Adolescents in South Korea: A Longitudinal Study

PURPOSE

The aims of this study were to examine relationships among peer victimization, supportive parenting, and depression in South Korean adolescents and the moderating effect of supportive parenting on the peer victimization-depression relationship.

METHODS

Data were drawn from the Korean Children and Youth Panel Survey performed from 2010 to 2016. The first-year middle-school panel collected from the first year of middle school to the first year of university was used, and the final sample size was 1750. Generalized estimating equation models were employed to examine relationships among peer victimization, supportive parenting, and depression.

RESULTS

About 6% of participants reported the experience of peer victimization at least once during the previous year. Females were more likely to report higher level of depression compared to males. Participants who were from lower family income, reported the past experience of peer victimization, and reported less supportive parenting were more likely to report higher level of depression compare to the counterpart. The moderating effect of supportive parenting on the association between peer victimization and depression was not statistically significant.

CONCLUSIONS

Participants who had experienced of peer victimization and less supportive parenting showed higher levels of depression. The supportive parenting did not have significant moderating effect on the relationship between peer victimization and depression.

PRACTICE IMPLICATIONS

Future research on adolescent depression should include development of interventions targeting both adolescent students' behaviors and their parents' styles of parenting aimed at the reducing the rate of peer victimization and the level of depression among adolescents in South Korea.

Common Substances of Abuse

Adolescent substance abuse remains common, with almost a third of adolescents admitting to ethanol use, and a quarter admitting to illicit drug use. It is essential for pediatricians to regularly screen adolescent patients for substance use, because early initiation of drug use has been associated with physical, behavioral, and social health risks. Adolescents abuse what is common and readily available; this includes ethanol, over-the-counter products, marijuana, and inhalants. The most common and effective clinical treatments for significant toxicity from substances of abuse is symptomatic and supportive care including hemodynamic support, respiratory support, and sedation to control psychomotor agitation.

Chronic sleep deprivation and gender-specific risk of depression in adolescents: a prospective population-based study

BACKGROUND

Chronic exposure to sleep deprivation may increase the risk of depression in young people who are particularly vulnerable to changes in sleep and mental health. Sleep deprivation and incident depression may also differ by gender. We investigated the prospective association between cumulative sleep deprivation and subsequent levels of depressive symptomatology among adolescents from a gender perspective.

METHODS

A longitudinal study of 3071 young people in the British Columbia Adolescent Substance Use Survey (BASUS) cohort with three sleep time and two depression measures over 12 months (2011-12). Multivariable linear regression models with interaction terms estimated gender-specific associations between self-reported chronic sleep deprivation and changes in depressive symptomatology; post-estimation analysis calculated adjusted mean depression scores for each level of cumulative sleep deprivation.

RESULTS

Cumulative sleep deprivation was associated with a monotonic increase in depression scores at follow-up in young women, but no consistent pattern was seen in young men. During follow-up, 15% of young women were chronically sleep deprived and 29% were depressed (CESD ≥24). Young women reporting chronic exposure to sleep deprivation had higher CESD scores at follow-up (21.50 points, [CI95 19.55-23.45]), than those reporting no history (16.59 [15.72-17.45]); that remained after multivariable adjustment (19.48 [17.59-21.38]).

CONCLUSION

Results suggested that chronic sleep deprivation increases the risk of major depression among young women. Mental health promotion for young people should include relevant strategies to ensure young women can achieve recommended amounts of sleep.

Recommendations for applying a multi-dimensional model of impulsive personality to diagnosis and treatment

The UPPS-P Model of Impulsive Personality, a prominent model of impulsive personality derived from the Five Factor Model of Personality, is a multi-dimensional model of impulsive personality that consists of negative urgency, lack of premeditation, lack of perseveration, sensation seeking, and positive urgency. The UPPS-P model has highlighted the importance of separating multidimensional traits due to the specificity of these traits corresponding to different risk behaviors. The goal of the current review paper is to make recommendations on how to apply the UPPS-P Model of Impulsive Personality, to diagnosis of and treatment for psychopathology. However, despite impulsivity being one of the most frequently used criteria for a number of clinical disorders, our review of the Diagnostic and Statistical Manual for Mental Disorders-5 found that the UPPS-P traits are not well represented in the diagnostic criteria, which we propose limits inferences about etiology and treatment targets. Additionally, research has largely focused on the importance of these traits for risk models; our review of the literature applying the UPPS-P traits to treatment processes and outcomes concluded that this area is not yet well studied. Here, we propose the specific application of the UPPS-P model to improve diagnosis and increase treatment effectiveness.

Associations of anxiety sensitivity and emotional symptoms with the subjective effects of alcohol, cigarettes, and cannabis in adolescents

Maladaptive emotional traits (anxiety sensitivity [AS], fear of anxiety-related sensations and consequences) and symptoms (major depressive disorder [MDD] and generalized anxiety disorder [GAD] symptoms) could play a role in altering sensitivity to the subjective effects of drugs of abuse in adolescents. Data were drawn from a longitudinal study of high school students in Los Angeles, CA, USA who completed surveys and reported past six-month use of alcohol (n=1054), cigarettes (n=297), or cannabis (n=706). At each of the four semi-annual waves during mid-adolescence (14-16years old), students reported positive and negative subjective drug effects experienced in the prior six-months. Controlling for covariates and the simultaneous covariance across the three domains of emotional dysfunction, AS was associated with more positive and negative cannabis effects (βs=0.09-0.16, ps<0.05), and MDD symptoms were associated with fewer negative cigarette effects (β=-0.13, p=0.04) and more negative cannabis effects (β=0.10, p=0.004). The acceleration of positive alcohol and cannabis effects over time was slower among adolescents with higher baseline MDD (MDD×time: β=-0.04, p=0.044) and GAD (GAD×time: β=-0.05, p=0.03) symptoms, respectively. These findings suggest that emotional dysfunction factors show differential and overlapping effects on subjective drug effects, which may vary across time. Future research should investigate emotional dysfunctions and subjective drug effects in relation to substance use across adolescence and emerging adulthood.

A longitudinal study of the reciprocal relationship between ever smoking and urgency in early adolescence

BACKGROUND

Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction.

METHODS

Participants (n=1906; 90% 10-11 years old, 50% female, 39% racial minorities at baseline) completed questionnaires 1-2 times per year starting in 5th grade and ending in 9th grade. Structural equation modeling allowed tests of bidirectional relationships between ever smoking and urgency controlling for pubertal status and negative affect at each wave.

RESULTS

Incidence of ever smoking increased from 5% to 27% over time, with current smoking around 5% at the last wave. Urgency at each wave predicted ever smoking at the next wave above and beyond covariates and prior smoking (all p<0.01). Likewise, with one exception, ever smoking predicted an increase in urgency at the subsequent wave above and beyond covariates and prior urgency (all p<0.05).

CONCLUSION

Results show that risk for smoking increases with higher levels of urgency and urgency increases secondary to engagement in smoking. Future work should therefore explore urgency as a point of prevention for smoking and smoking cessation as a means to mitigate mood-based impulsivity.

Residential Mobility, Transience, Depression, and Marijuana Use Initiation Among Adolescents and Young Adults

Marijuana use initiation is associated with numerous health and behavioral consequences, particularly among young adolescents. Finding easily identifiable risk markers for marijuana initiation is an important step for targeting primary and secondary prevention efforts. This study used data from the 2010-2014 National Survey on Drug Use and Health to evaluate the association between residential mobility (no mobility, low mobility, high mobility [ie, transience]), and major depressive episode(s) (MDE) on marijuana initiation among adolescents (12-17) and young adults (18-20). Age-stratified logistic regression models indicated that among 12- to 13-year-old adolescents, mobility in the past 5 years and past year MDE have a multiplicative effect on the odds of past year marijuana initiation. Among adolescents aged 14 to 15 years, both mobility and MDE were independently associated with marijuana initiation, but there was no interaction. Among older adolescents (aged 16-17 years), only transience (⩾3 moves in the past 5 years) was associated with marijuana use initiation, and although MDE was significantly associated with marijuana initiation, there was no interaction with mobility. Among young adults, mobility was not associated with marijuana initiation. Residential mobility among young adolescents is an easily identifiable risk marker that may serve as an indicator for physical and mental health professionals, school personnel, and parents to use in targeting both depression and marijuana prevention efforts.

The ABCD study of neurodevelopment: Identifying neurocircuit targets for prevention and treatment of adolescent substance abuse

Substance use disorders (SUD) can be considered developmental disorders in light of their frequent origins in substance initiation during adolescence. Cross-sectional functional magnetic resonance imaging (fMRI) studies of adolescent substance users or adolescents with SUD have indicated aberrations in brain structures or circuits implicated in motivation, self-control, and mood-regulation. However, attributing these differences to the neurotoxicological effects of chronic substance use has been problematic in that these circuits are also aberrant in at-risk children, such as those with prenatal substance exposure, externalizing disorders (such as conduct disorder), or prodromal internalizing disorders such as depression. To better isolate the effects of substance exposure on the adolescent brain, the newly-launched Adolescent Brain Cognitive Development (ABCD) study, funded by the National Institutes of Health, will follow the neurodevelopmental trajectories of over 11,000 American 9/10-year-olds for 10 years, into emerging adulthood. This study will provide a rich open-access dataset on longitudinal interactions of neurodevelopment, environmental exposures, and childhood psychopathology that confer addiction risk. The ABCD twin study will further clarify genetic versus experiential influences (e.g., substance use) on neurodevelopmental and psychosocial outcomes. Neurocircuitry thought to regulate mood and behavior has been directly normalized by administration of psychoactive medications and by cognitive therapies in adults. Because of this, we contend that ABCD project data will be a crucial resource for prevention and treatment of SUD in adolescence because its cutting-edge neuroimaging and childhood assessments hold potential for discovery of additional targetable brain differences earlier in development that are prognostic of (or aberrant in) SUD. The ABCD sample size will also have the power to illuminate how sex differences, environmental interactions and other individual differences interact with neurodevelopment to inform treatment in different groups of adolescents.

Violence Victimization, Social Support, and Papanicolaou Smear Outcomes: A Longitudinal Study from Adolescence to Young Adulthood

BACKGROUND

African American youth are among those at greatest risk for experiencing violence victimization. Notably, the mortality rate of cervical cancer for African American women is also twice that of white women. To date, we know of no literature using longitudinal data to examine how violence victimization relates to Papanicolaou (Pap) smear results or cervical cancer in this population. Our study examines how violence victimization during adolescence (age 15 to 18) influences psychological distress, perceived social support, heavy substance abuse, and sexual risk behaviors during emerging adulthood (age 20 to 23), and subsequent Pap smear outcomes during young adulthood (age 29 to 32).

METHOD

This study is based on 12 waves of data collected in a longitudinal study of 360 African American women from mid-adolescence (ninth grade, mean age = 14.8 years) to young adulthood (mean age = 32.0 years). We used structural equation modeling analysis to examine the hypothesized model.

RESULT

Violence victimization during adolescence had a direct effect on decreased social support, increased psychological distress, and increased heavy cigarette use during emerging adulthood. Better social support was also associated with fewer sexual partners during emerging adulthood and lower odds of abnormal Pap smear results during young adulthood. The effect of violence victimization on abnormal Pap smear was mediated by social support.

CONCLUSION

Our results show that violence victimization during adolescence has long-term negative effects through multiple pathways that persist into adulthood. Our findings also suggest that social support may help to compensate against other risk factors. Interventions designed to address the perceived support may help victims cope with their experience.

Negative affect in at-risk youth: Outcome expectancies mediate relations with both regular and electronic cigarette use

Despite the general trend of declining use of traditional cigarettes among young adults in the United States, alternative high school students continue to smoke cigarettes and electronic cigarettes at rates much higher than do students attending regular high schools. Challenging life circumstances leading to elevated levels of negative affect may account for increased smoking behavior in this population. Further, a belief in the negative affect-reducing qualities of nicotine may mediate this effect. The current study tested the hypothesis that negative reinforcing outcome expectancies mediate the relationship between negative affect on smoking susceptibility in nonusers, smoking frequency in users, and smoking experimentation in the overall sample. Results support the hypothesis that negative affect in alternative high school students is correlated with smoking experimentation, smoking willingness, and smoking frequency and that the relationship between negative affect and smoking behavior outcomes is mediated by negative reinforcing outcome expectancies (i.e., beliefs in the negative affect-reducing effects of smoking). This finding was supported for both cigarettes and electronic cigarettes and coincides with a rapid increase in the number of high school students nationally who have experimented with electronic cigarettes. Future antismoking initiatives directed at at-risk youth should consider integrating healthier negative affect reduction techniques to counter the use of nicotine products. (PsycINFO Database Record

Combining Trait Models of Impulsivity to Improve Explanation of Substance Use Behaviour

The UPPS–P model of impulsivity is gaining popularity among personality and substance use researchers, but questions remain as to whether its five facets have incremental validity in explaining substance use over a more parsimonious model specifying only two facets: reward drive and rash impulsiveness. In three cross–sectional studies (total N = 486), we investigated whether the novel components of the UPPS–P model (negative Urgency, Premeditation, Perseverance, Sensation seeking, Positive urgency) predicted typical and problematic alcohol and cannabis use after accounting for reward drive, rash impulsiveness and trait neuroticism (assessed with the Eysenck Personality Questionnaire). Reward drive and rash impulsiveness scores were calculated using principal components analysis of multiple scales, including UPPS–P premeditation and sensation seeking. Results showed that rash impulsiveness was a robust predictor of typical and problematic substance use. The novel facets of the UPPS–P did not improve prediction of typical substance use. The urgency scales inconsistently predicted problematic use. Specifically, negative urgency predicted one of three measures of negative consequences from alcohol use, and positive urgency only predicted negative consequences from cannabis use. Results suggest that the three novel facets of the UPPS–P model add little over a two component model in explaining substance use, although may provide preliminary evidence for the utility of a revised global urgency construct in explaining problematic substance use.

UPPS-P model impulsivity and marijuana use behaviors in adolescents: A meta-analysis

BACKGROUND

Impulsivity is often included as a risk factor in models of adolescent marijuana use behaviors; however, the magnitude of the association between impulsivity and marijuana use behaviors is variable across studies. The present study reviewed existent literature to 1) quantify the relationship between separable impulsivity-related traits and both marijuana use and negative marijuana consequences and 2) quantify the size of the effect of gender on these relationships.

METHOD

Thirty-eight studies (41 independent samples) were meta-analyzed using a random effects model to examine the relationship between impulsivity traits and marijuana use behaviors.

RESULTS

Marijuana use was significantly related to all impulsivity-related traits except lack of perseverance (r's ranging from 0.13-0.23, p's<0.01). Negative marijuana consequences were only significantly related to sensation seeking, lack of planning, and positive urgency (r's ranging from 0.37-0.39, p's<0.01). Effects were small for marijuana use, but medium for negative marijuana consequences. Gender was not a significant moderator of any relationships.

CONCLUSIONS

Impulsivity-related traits had more robust relationships with negative marijuana consequences than marijuana use, suggesting impulsivity-related traits are important in differentiating adolescents most likely to experience negative consequences from marijuana use. Few relationships examined gender and many of the impulsivity-related traits, other than sensation seeking. Data and trends suggest a more multi-dimensional approach to marijuana use and consequences is warranted.

Family dynamics and alcohol and marijuana use among adolescents: The mediating role of negative emotional symptoms and sensation seeking

The literature indicates a close relationship between family dynamics and psychoactive substance use among adolescents, and multi-causality among substance use-related problems, including personal adolescent characteristics as potential influential aspects in this relationship. The purpose of this study is to investigate the role of emotional symptoms and sensation seeking as mediators in the relationship between family dynamics and alcohol and marijuana use among adolescents. The sample consisted of 571 high school students with a mean age of 14.63, who completed the Communities That Care Youth Survey in its Spanish version. We propose and test a mediation-in-serial model to identify the relationships between the study variables. The results of the mediation models indicate that, in most cases, the relationship between family dynamics and the substance use variables is meaningfully carried through the proposed mediators, first through negative emotional symptoms, and then through sensation seeking. The meaning of the mediation varies as a function of the facet of family dynamics (conflict or attachment) and the use aspect (age of onset, frequency of use, and use intention). We discuss the implications of these findings for intervention and prevention strategies.

Transdiagnostic processes linking anxiety symptoms and substance use problems among adolescents

Numerous anxiety syndromes co-occur with substance use problems in adolescents, though the mechanisms underlying these comorbidities are not well understood. There are 3 transdiagnostic processes-anxiety sensitivity (fear of anxiety-related sensations), distress tolerance (capacity to withstand emotional distress), and negative urgency (propensity to respond impulsively to negative emotion)-that have been implicated in various anxiety and substance use problems. To examine whether anxiety sensitivity, distress tolerance, and negative urgency statistically mediated relations between symptoms of 3 different anxiety disorders (social anxiety, generalized anxiety, and panic disorders) and alcohol and cannabis use problems, cross-sectional analysis of high school students in Los Angeles (N = 3002) was assessed via paper and pencil questionnaires. When mediators were entered simultaneously, negative urgency accounted for a significant 33 to 85% of the covariance between anxiety symptomatology and substance use problems over and above the other trandiagnostic processes. This pattern was consistent across all 3 anxiety syndromes and both alcohol and cannabis problems. Anxiety sensitivity and distress tolerance did not account for positive associations between anxiety symptoms and substance use problems. Negative urgency may be an important mechanism underlying the relationship between various types of anxiety and substance use problems in adolescence, and thus represents a possible target for preventive interventions targeting adolescent anxiety and substance use.

Social Self-Control Is a Statistically Nonredundant Correlate of Adolescent Substance Use

The social self-control scale (SSCS), which taps provocative behavior in social situations, was compared with five potentially overlapping measures (i.e., temperament-related impulsivity, psychomotor agitation-related self-control, perceived social competence, and rash action in response to negative and positive affectively charged states) as correlates of tobacco use and other drug use among a sample of 3,356 ninth-grade youth in Southern California high schools. While there was a lot of shared variance among the measures, the SSCS was incrementally associated with both categories of drug use over and above alternate constructs previously implicated in adolescent drug use. Hence, SSC may relate to adolescent drug use through an etiological pathway unique from other risk constructs. Given that youth who tend to alienate others through provocative social behavior are at risk for multiple drug use, prevention programming to modify low SSC may be warranted.
