Alcohol abuse among adolescents and suicide risk - is there a correlation?

Introduction: Adolescent alcohol abuse is a critical public health issue with far-reaching consequences for individual development and societal well-being. Adolescent alcohol consumption poses significant health risks, particularly due to its effects on brain development and its association with increased suicide risk. Purpose of the work: This study aims to investigate the relationship between alcohol abuse and suicide risk in adolescents. Materials and methods: A comprehensive analysis of research papers available on PubMed and Google Scholar was undertaken using the search terms including the following keywords: alcohol abuse/ alcohol abuse in adolescence/ alcohol consumption in adolescence/ alcohol abuse and suicide risk in adolescence/ suicide risk factors in adolescence/ suicidal tendencies among teenagers. Conclusions:Adolescent alcohol abuse has profound implications for brain development and mental health, significantly increasing the risk of suicide. Effective public health strategies, including early intervention, education, and strong support systems, are essential to mitigate these risks and promote healthier environments for young individuals. Addressing the underlying causes of alcohol abuse and providing targeted support can reduce its long-term consequences and improve adolescent well-being.

Agenda-setting in policies related to high-risk sexual behaviours, stimulants, and alcohol abuse in Iranian adolescents

BackgroundThis research article retrospectively analyses the agenda-setting approach of policies concerning high-risk sexual behaviours, stimulant and alcohol abuse among Iranian adolescents.MethodsThis qualitative case study policy analysis involved analysing 51 national documents and conducting interviews with 49 policy-makers and executives. Purposive sampling with a snowball strategy and semi-structured interviews were used. The data was analysed using the framework analysis method, with Kingdon’s multiple streams framework serving as the analytical framework.ResultsThe study has identified the confluence of several factors, including the problem stream, the policy stream and the political stream. Within the problem stream, several factors contributed, such as the prevalence of high-risk behaviours, strong scientific evidence on these behaviours, changes in human immunodeficiency virus (HIV) transmission patterns, increased statistics of poisoning and deaths related to alcohol abuse, and the visit of Iran’s supreme leader to the slums of Mashhad city. The policy stream has two periods of denial and acceptance. The denial period includes considering these high-risk behaviours to be the consequences of western culture, emphasis on the religious aspects and sinfulness of these behaviours, resisting the prevalence of anomalous behavioural patterns, abstinence and religious obligation of chastity, and avoiding ethical corruption. The acceptance period includes adolescents training, fear messages, promotional and cultural activities, parent training, school staff training, providing psychiatric services for withdrawal, counselling and reference to receive specialized services. The political stream involves global attention towards non-communicable diseases and high-risk behaviours, and the significant impact of preventing these behaviours during adolescence on the health status of society. Also, the supreme leader’s attention to social harms, and the establishment of the National Committee for Prevention and Control of Alcohol, have played significant roles.ConclusionsWhile the problem stream helped to highlight the problem and increase policy-makers’ attention, the politics stream played a significant role. Despite international evidence on the effectiveness of training in sexual issues in reducing high-risk behaviours, it did not succeed in being added to the agenda. The policy stream was heavily influenced by ideology and the political parties in power, affecting evidence-based policy-making. In countries with an ideological approach, the political stream plays a vital role in setting problems on the agenda.

The Influence of Family and Peer on Adolescent Alcohol Addiction

Substance abuse among adolescents is a significant concern today. Alcohol, as the most accessible addictive substance, is also the most likely to lead to adolescent alcohol consumption and eventually to the development of alcohol addiction. Alcohol addiction in adolescents can have harmful, even long-lasting effects on their psychology and physiology. Previous literatures have examined factors contributing to adolescent alcohol addiction from multiple perspectives. However, there are relatively fewer systematic reviews of family and peer influences on adolescent alcohol abuse. Therefore, this article aims to integrate the findings of previous literatures and address the impact of family and peers on adolescent alcohol consumption and alcohol addiction. Parents’ and peers’ open attitudes toward alcohol, negative peer and parent-child relationship, unhappy marital status, as well as peers’ problematic behaviors could assumably increase the likelihood of adolescent alcohol use. By discussing and analyzing two kinds of intimate relationships of adolescents, family and peers, this paper calls for social institutions to devote more attention to adolescent drinking behavior and their social relationships to prevent adolescent alcohol addiction and the harm caused by alcohol abuse. In addition, previous studies were mostly correlational cross-sectional studies, which had some limitations. Future studies could focus on longitudinal experiments and consider excluding confounding factors to obtain causal results.

Relationship between emotional instability and risk of alcohol abuse among adolescents: the moderating role of predisposition to engage in risky behaviors

There is growing evidence that alcohol abuse among adolescents is a major public health concern. Understanding the risk factors associated with adolescent alcohol misuse is crucial for the development of prevention programs. Our study aimed to examine whether general attitudes toward health risk behaviors (i.e., predisposition to engage in risky behaviors) moderate the association between emotional instability (neuroticism as a stable personality factor) and adolescent alcohol abuse. A population-based sample of 688 Romanian adolescents completed several standardized instruments, including a measure of the current risk of alcohol abuse, the Neuroticism scale from the Big Five Inventory, and a subscale (Health/Safety) from the Risk Behaviors Scale [71]. The risk of alcohol abuse was positively associated with both emotional instability (n = 673; r = 0.345; p < 0.001) and predisposition to engage in risky behaviors (n = 688; r = 0.424; p < 0.001). A positive relationship was also found between emotional instability and the predisposition to engage in risky behaviors (n = 673; r = 0.129; p = 0.001). Hierarchical linear multiple regression analysis provided support for the moderation relationship. In summary, the predisposition to engage in risky behaviors may act as an amplifying factor by increasing the risk associated with emotional instability. Some practical implications for preventive interventions are discussed.

Toxicological evaluation of alcohol and substance abuse in children and adolescents

Unhealthy behaviors such as use of alcohol and drug usually begin during adolescence. Izmir is on transit route for illicit substance due to geographical situation. Children and adolescents are the most important threatened group in terms of alcohol and substance abuse. In this study, it was aimed to investigate alcohol and substance use profile of children and adolescents in Izmir/Turkey with the toxicological analysis results obtained from Addiction Toxicology Laboratory. Urine and blood samples of 4524 cases at and under the age of 18 years coming from various departments to the laboratory in 2015–2016 were analyzed by enzymatic immunoassay. Information and analysis results of the cases were obtained by retrospective analysis of the hospital system. 83,3% of the cases were male and the mean age was 16,69 ± 1,63. Alcohol and/or substance use was determined in 13,2% of the cases. Among the cases with positive results of analysis, cannabis (33%) was mostly detected and was followed by amphetamine type stimulants (ATS, 15%), polysubstance use (15%) and alcohol (13%). While cannabis, polysubstance use and ATS were the most common in male, ethyl alcohol, ATS and benzodiazepine were mostly detected in female. There was a significant increase in the substance use rate in 2016 compared to the previous year. A substance use profile was obtained through drug testing in adolescents who are in the risk group for substance use. In this context, our data will be indicative for the development of new and more effective preventive strategies targeting children and adolescents.

Maternal Separation Alters Ethanol Drinking and Reversal Learning Processes in Adolescent Rats: The Impact of Sex and Glycine Transporter Type 1 (GlyT1) Inhibitor.

Adverse early life experiences are associated with an enhanced risk for mental and physical health problems, including substance abuse. Despite clinical evidence, the mechanisms underlying these relationships are not fully understood. Maternal separation (MS) is a commonly used animal model of early neglect. The aim of the current study is to determine whether the N-methyl-D-aspartate receptor (NMDAR)/glycine sites are involved in vulnerability to alcohol consumption (two-bottle choice paradigm) and reversal learning deficits (Barnes maze task) in adolescent rats subjected to the MS procedure and whether these effects are sex dependent. By using ELISA, we evaluated MS-induced changes in the NMDAR subunits (GluN1, GluN2A, GluN2B) expression, especially in the glycine-binding subunit, GluN1, in the prefrontal cortex (PFC) and ventral striatum (vSTR) of male/female rats. Next, we investigated whether Org 24598, a glycine transporter 1 (GlyT1) inhibitor, was able to modify ethanol drinking in adolescent and adult male/female rats with prior MS experience and reversal learning in the Barnes maze task. Our findings revealed that adolescent MS female rats consumed more alcohol which may be associated with a substantial increase in GluN1 subunit of NMDAR in the PFC and vSTR. Org 24598 decreased ethanol intake in both sexes with a more pronounced decrease in ethanol consumption in adolescent female rats. Furthermore, MS showed deficits in reversal learning in both sexes. Org 24598 ameliorated reversal learning deficits, and this effect was reversed by the NMDAR/glycine site inhibitor, L-701,324. Collectively, our results suggest that NMDAR/glycine sites might be targeted in the treatment of alcohol abuse in adolescents with early MS, especially females.

Dimensions of the relationship between the level of anxiety, the perception of social support and the risk of alcohol abuse in adolescents

In this article, the methodological framework and the results of a study is aimed at testing whether the social support of the family, which a teenager perceives as such, moderates the relationship between the specific symptoms of anxiety and the risk of alcohol abuse. The results we have obtained, suggests that social support from the family can help alleviate the risk of alcohol abuse among adolescents experiencing anxiety. In the context of current social, cultural and economic changes, as well as age-specific challenges, adolescence is seen as an insidious stage in the development of the human individual. For this reason, increased attention to the need for support can help prevent the risks to adolescents' physical and mental health, including the use of harmful substances.

Sex-specific effects of adolescent intermittent ethanol exposure-induced dysregulation of hippocampal glial cells in adulthood.

Adolescent alcohol abuse is a significant public health concern, with approximately 4.3 million U.S. adolescents reporting monthly binge drinking. Excessive ethanol consumption during adolescence has been linked to dysregulation of the neuroimmune system, particularly in the hippocampus. Because there are sex differences in both neuroimmune responses and ethanol's pharmacologic actions, this study tested whether there were disparate effects based on sex in glial cells and neurodegeneration in adulthood after the adolescent intermittent ethanol (AIE) model. Male and female adolescent Sprague-Dawley rats underwent AIE. In adulthood, immunohistochemical techniques were utilized to determine the effects of AIE on astrocytes and microglia, and Fluoro-Jade C (FJC) was used to assess neurodegeneration in the hippocampus. AIE exposure significantly increased astrocyte activation in the cornu ammonis 1 (CA1), CA2/3, and dentate gyrus (DG) in both male and female rats with no discernible sex differences in immunoreactivity. Likewise, the number of GFAP+cells was significantly increased by AIE across the hippocampus. In our microglial assessment, AIE only led to increased Iba1 immunoreactivity in the CA1 but not CA2/3 or DG regions. However, the number of Iba1+ cells was increased by AIE in both the CA1 and DG subregions. In the DG, the ethanol effect was observed in both sexes, but in the CA1, AIE-induced increased Iba1 cells were only observed in females. In regard to neurodegeneration, there were no persisting AIE effects on FJC+cells. These findings indicate that AIE alters hippocampal glial cells in adulthood, in the absence of active neurodegeneration. However, while AIE induced long-term elevation of astroglial measures in both males and females, persisting AIE-induced microglial activation was more sparse and sex-dependent. While the majority of these findings suggest that AIE has similar effects on glial morphology and number between males and females, additional work should determine whether there are molecular differences as well as innate sex differences in glial interaction with AIE's influence on glial functions in behavior.

The long-term mental health outcome of adolescent with depression and alcohol abuse comorbidity

Abstract Background Alcohol abuse often co-occurs with adolescent depression and about 1-2% suffer from the dual diagnosis in adolescence. This group is often undertreated or receive inadequate treatment for either of the conditions. Both conditions affect the developing brain and poor long-term outcome might be a potential risk. Yet, long-term follow-up studies are scarce. The aim of this study was to analyse if adolescent depression and alcohol abuse predict poorer mental health in adulthood compared to individuals without either or both conditions. Methods A community-based sample of individuals with adolescent depression in 1991-93 and matched non-depressed peers were followed up using a structured diagnostic interview after 15 years. The participation rate was 65% (depressed n = 227; non-depressed controls n = 155). Information on alcohol abuse in adolescence was collected at baseline with a structured interview. The outcome was mental disorders between the ages 19-31 years; information on depression and alcohol abuse was collected at the follow-up with a structured diagnostic interview. The statistical method used was binary logistic regression. Results Adolescents with depression and alcohol abuse had an excess risk of recurrence of depression (OR 2.12, p < 0.05) and alcohol abuse (OR 6.72, p < 0.01) in adulthood, compared with adolescents with depression only, even when adjusted for confounders. Adolescents with alcohol abuse only had not significantly worse long-term outcome compared with their healthy peers. Conclusions The co-occurrence of depression and alcohol abuse in adolescence is associated with long-lasting health consequences compared to either condition alone. This finding indicates that there is a need to prioritize this group of patients that is at risk of suboptimal treatment, and to further develop effective treatment adjusted to the co-occurring condition. Key messages The co-occurrence of adolescent depression and alcohol abuse has long lasting mental health consequences compared to either condition alone. Improved treatment methods are important for this group of adolescents.

Microglia Phenotypes Following the Induction of Alcohol Dependence in Adolescent Rats.

Activation of the innate immune system may play a role in the development of alcohol use disorders (AUDs), which often originate with adolescent alcohol abuse. A key player in the innate immune system is microglia, the activation of which occurs along a spectrum from proinflammatory, or M1-like, to anti-inflammatory, or M2-like, phenotypes. Adolescent, male rats were gavaged with ethanol (EtOH) or isocaloric control diet every 8hours for 4days and then sacrificed at 0, 2, 7, and 14days later. Microglia were isolated from the entorhinal cortex and hippocampus by Percoll gradient centrifugation, labeled with surface antigens for activation, and analyzed by flow cytometry. Polarization states of microglia, defined as CD11b+ CD45low cells, were determined by the expression of M1 surface markers, major histocompatibility complex (MHC) II, CD32, and CD86, and M2 surface marker, CD206 (mannose receptor). Cytokine gene expression was measured by reverse transcriptase polymerase chain reaction. Isolated cells were a highly enriched population (>95% pure) of microglia/macrophages according to CD11b immunoreactivity. EtOH rats showed the most dramatic increases in microglia activation markers CD11b and CD45, and M1 (MHC-II) and M2 (CD206) markers at T2, when additional M1 markers CD86 and CD32 were also increased. Surprisingly, proinflammatory gene expression of CCL2, IL-1β, IL-6, and TNF-α generally was decreased at all time points in EtOH rats except for IL-6 which was increased at T0 and TNF-α which was not changed at T0 in either region. Simultaneously, BDNF expression was increased at T2 and T7, while IGF1 and TGF-β gene expression was decreased. Arginase was also increased at T0 in hippocampus, but not changed by alcohol otherwise. These data show that microglia phenotype after alcohol dependence is not a simple M1 or M2 classification, though more indicators of an anti-inflammatory phenotype were observed. Determining microglia phenotype is critical for understanding their role in the development of AUDs.

Adolescent neuroimmune function and its interaction with alcohol.

Adolescence is an evolutionarily conserved developmental period associated with behavioral change, including increased risk-taking and alcohol use. Experimentation with alcohol typically begins in adolescence and transitions to binge-like patterns of consumption. Alcohol exposure during adolescence can alter normative changes in brain structure and function. Understanding mechanisms by which ethanol impacts neurodevelopmental processes is important for preventing and ameliorating the deleterious consequences of adolescent alcohol abuse. This review focuses on the neuroimmune system as a key contributor to ethanol-induced changes in adolescent brain and behavior. After brief review of neuroimmune system development, acute and chronic effects of ethanol on adolescent neuroimmune functioning are addressed. Comparisons between stress/immunological challenges and ethanol on adolescent neuroimmunity are reviewed, as cross-sensitization is relevant during adolescence. The mechanisms by which ethanol alters neuroimmune functioning are then discussed, as they may portend development of neuropathological consequences and thus increase vulnerability to subsequent challenges and potentiate addictive behaviors.

The persistent impact of adolescent binge alcohol on adult brain structural, cellular, and behavioral pathology: A role for the neuroimmune system and epigenetics.

Adolescence is a critical neurodevelopmental window for maturation of brain structure, neurocircuitry, and glia. This development is sculpted by an individual's unique experiences and genetic background to establish adult level cognitive function and behavioral makeup. Alcohol abuse during adolescence is associated with an increased lifetime risk for developing an alcohol use disorder (AUD). Adolescents participate in heavy, episodic binge drinking that causes persistent changes in neurocircuitry and behavior. These changes may underlie the increased risk for AUD and might also promote cognitive deficits later in life. In this chapter, we have examined research on the persistent effects of adolescent binge-drinking both in humans and in rodent models. These studies implicate roles for neuroimmune signaling as well as epigenetic reprogramming of neurons and glia, which create a vulnerable neuroenvironment. Some of these changes are reversible, giving hope for future treatments to prevent many of the long-term consequences of adolescent alcohol abuse.

Regulation of the deleterious effects of binge-like exposure to alcohol during adolescence by α7 nicotinic acetylcholine receptor agents: prevention by pretreatment with a α7 negative allosteric modulator and emulation by a α7 agonist in alcohol-preferring (P) male and female rats.

Binge-like alcohol consumption during adolescence associates with several deleterious consequences during adulthood including an increased risk for developing alcohol use disorder (AUD) and other addictions. Replicated preclinical data has indicated that adolescent exposure to binge-like levels of alcohol results in a reduction of choline acetyltransferase (ChAT) and an upregulation in the α7 nicotinic receptor (α7). From this information, we hypothesized that the α7 plays a critical role in mediating the effects of adolescent alcohol exposure. Male and female P rats were injected with the α7 agonist AR-R17779 (AR) once during 6 time points between post-natal days (PND) 29-37. Separate groups were injected with the α7 negative allosteric modulator (NAM) dehydronorketamine (DHNK) 2 h before administration of 4 g/kg EtOH (14 total exposures) during PND 28-48. On PND 75, all rats were given access to water and ethanol (15 and 30%) for 6 consecutive weeks (acquisition). All rats were then deprived of EtOH for 2 weeks and then, alcohol was returned (relapse). Administration of AR during adolescence significantly increased acquisition of alcohol consumption during adulthood and prolonged relapse drinking in P rats. In contrast, administration of DHNK prior to binge-like EtOH exposure during adolescence prevented the increase in alcohol consumption observed during acquisition of alcohol consumption and the enhancement of relapse drinking observed during adulthood. The data indicate that α7 mediates the effects of alcohol during adolescence. The data also indicate that α7 NAMs are potential prophylactic agents to reduce the deleterious effects of adolescent alcohol abuse.

General Anesthetic Exposure During Early Adolescence Persistently Alters Ethanol Responses

Adolescent alcohol abuse can lead to behavioral dysfunction and chronic, relapsing alcohol use disorder (AUD) in adulthood. However, not all adolescents that consume alcohol will develop an AUD; therefore, it is critical to identify neural and environmental risk factors that contribute to increases in susceptibility to AUDs following adolescent alcohol (ethanol [EtOH]) exposure. We previously found that adolescent anesthetic exposure led to strikingly similar behavioral and neural effects as adolescent alcohol exposure. Therefore, we tested the hypothesis that general anesthetic exposure during early adolescence would alter EtOH responses consistent with an exacerbation of the adolescent alcohol phenotype. To test this hypothesis, early-adolescent male Sprague-Dawley rats were exposed for a short duration to the general anesthetic isoflurane and tested on multiple EtOH-induced behaviors in mid-late adolescence or adulthood. Adolescent rats exposed to isoflurane exhibited decreases in sensitivity to negative properties of EtOH such as its aversive, hypnotic, and socially suppressive effects, as well as increases in voluntary EtOH intake and cognitive impairment. Select behaviors were noted to persist into adulthood following adolescent isoflurane exposure. Similar exposure in adults had no effects on EtOH sensitivity. This study demonstrates for the first time that early-adolescent isoflurane exposure alters EtOH sensitivity in a manner consistent with an exacerbation of adolescent-typical alcohol responding. These findings suggest that general anesthetic exposure during adolescence may be an environmental risk factor contributing to an enhanced susceptibility to developing AUDs in an already vulnerable population.

THE TESTOSTERONE-CORTISOL MODEL AS A WAY TO UNDERSTAND THE MECHANISM OF ALCOHOL DEPENDENCE WHICH STARTED IN PUBERTY

The aim: Is to analyze the role of testosterone and cortisol in the mechanism of alcohol use disorders formation for further development of early diagnosis and prevention methods. Materials and methods: 155 adolescents at the preclinical stages of alcohol use disorders formation and 87 young patients with diagnosed alcohol dependence were studied by enzyme-linked immunoassay techniques. Results: The analysis of the obtained materials shows that the onset of search behaviors on alcohol consumption, frequency and alcohol abuse in adolescents occur with the participation of age-related processes of somatic puberty and the related syndromes of hormonal tension. The phasing of development and course of alcoholic disease includes pubertal age and alcohol-induced changes in the internal environment of the body. There is an increase in the concentration of testosterone and cortisol that initiates interest in alcohol first, and then under the influence of its toxic effect, the level of these hormones decreases. It should be borne in mind that significant differences in hormone concentrations were observed within the regulatory framework. Conclusions: An increase of testosterone and cortisol levels in puberty, combined with regular consumption of alcohol, may indicate a risk of addiction early. Further decrease of the levels of these hormones along with an increase of the frequency of alcohol consumption may be an early diagnostic feature of the alcohol use disorders.

Enduring alterations in hippocampal astrocytesynaptic proximity following adolescent alcohol exposure: reversal by gabapentin.

Adolescent alcohol abuse is a substantive public health problem that has been the subject of intensive study in recent years. Despite reports of a wide range of effects of adolescent intermittent ethanol (AIE) exposure on brain and behavior, little is known about the mechanisms that may underlie those effects, and even less about treatments that might reverse them. Recent studies from our laboratory have indicated that AIE produced enduring changes in astrocyte function and synaptic activity in the hippocampal formation, suggesting the possibility of an alteration in astrocyte-neuronal connectivity and function. We utilized astrocyte-specific, membrane restricted viral labeling paired with immunohistochemistry to perform confocal single cell astrocyte imaging, three-dimensional reconstruction, and quantification of astrocyte morphology in hippocampal area CA1 from adult rats after AIE. Additionally, we assessed the colocalization of astrocyte plasma membrane labeling with immunoreactivity for AMPA-(α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) glutamate receptor 1, an AMPA receptor subunit and established neuronal marker of excitatory synapses, as a metric of astrocyte-synapse proximity. AIE significantly reduced the colocalization of the astrocyte plasma membrane with synaptic marker puncta in adulthood. This is striking in that it suggests not only an alteration of the physical association of astrocytes with synapses by AIE, but one that lasts into adulthood - well after the termination of alcohol exposure. Perhaps even more notable, the AIE-induced reduction of astrocyte-synapse interaction was reversed by sub-chronic treatment with the clinically used agent, gabapentin (Neurontin), in adulthood. This suggests that a medication in common clinical use may have the potential to reverse some of the enduring effects of adolescent alcohol exposure on brain function. All animal experiments conducted were approved by the Duke University Institutional Animal Care and Use Committee (Protocol Registry Number A159-18-07) on July 27, 2018.

Early life temperamental anxiety is associated with excessive alcohol intake in adolescence: A rhesus monkey (Macaca mulatta) model.

Teenage alcohol abuse is a major health concern, particularly because the majority of alcohol consumed by teenagers is via binge drinking, a known risk factor for increasing the likelihood for the development of future alcohol use disorders (AUDs). Identifying individuals at risk for excessive alcohol intake in adolescence is a step toward developing effective preventative measures and intervention programs. As adults with AUDs tend to self-medicate their anxiety with alcohol, this longitudinal study assesses the role of infant anxiety-like temperament in the development of adolescent alcohol abuse using a nonhuman primate model. From birth until they were 5 months of age, behaviors of 64 rhesus monkeys (Macaca mulatta) were coded twice a week using an objective mother-infant scoring system that included behaviors traditionally used to assess anxiety and fearfulness in rhesus monkeys. When subjects were four months old, plasma cortisol was obtained. When subjects were adolescents (Mage = 44.88 months), another plasma cortisol sample was obtained about one month prior to allowing them unfettered access to an 8.4% (v/v) aspartame-sweetened alcohol solution for one hour a day over five-to-seven weeks. Results showed that behavioral indications of anxiety-like temperament in infancy, including high levels of mother-infant mutual ventral contact, low levels of environmental exploration, and low levels of interactions with peers were predictive of high adolescent alcohol intake (ie, drinking to intoxication). Plasma cortisol levels in infancy were positively correlated with plasma cortisol in adolescence, and both were positively correlated with high adolescent alcohol intake. Our findings indicate that high levels of traditional anxiety-like behaviors measured in the context of mother-infant interactions, coupled with high infant and adolescent plasma cortisol, are associated with binge-like high alcohol intake in adolescence, suggesting that individuals at risk for developing an AUD later in life may be determined, at least in part, by assessing their physiological and behavioral propensity for anxiety early in life.

Trait and ability emotional intelligence as predictors of alcohol consumption in adolescents.

Past studies have suggested that emotional intelligence (EI) is a new construct that may help to explain alcohol abuse. This study is one of the first to examine the predictive capacity of both trait and ability EI, based on the Mayer and Salovey model, with regards to distinct variables of alcohol consumption in an adolescent population. A survey was conducted on 844 school children who completed a self-report and performance-based EI test, as well as a selection of items on alcohol consumption. Regression analyses revealed that trait EI was the most predictive. Clarity and emotional Repair showed significant negative correlations with alcohol consumption, as opposed to emotional Attention. Likewise, the abilities of Perceiving and Using emotions were found to be protective factors for consumption in schoolchildren. The results suggest that trait and ability EI are complementary dimensions that may help in the understanding and intervention of alcohol abuse in adolescents. The results are discussed in the EI research context, as well as their educational implications and future research lines.

Emotion regulation and alcohol abuse in second-generation immigrant adolescents: The protective role of cognitive reappraisal.

The individual predictors of drinking behaviors among second-generation immigrant adolescents are still understudied. This study investigated emotion regulation strategies and alcohol abuse in 472 adolescents (86 second-generation immigrants and 386 Italian natives; age range: 17-18). The Emotion Regulation Questionnaire and the Alcohol Use Disorder Identification Test were used to assess cognitive reappraisal, emotional suppression, and alcohol abuse, respectively. Immigrants reported lower alcohol abuse than natives. A negative relationship between cognitive reappraisal and alcohol abuse was found for immigrants, but not for natives. Specifically, cognitive reappraisal was a protective factor against alcohol abuse only for immigrant adolescents. Clinical and research implications are discussed.
