Reciprocal relations between internalizing symptoms and frequency of alcohol use: Findings from a longitudinal study of Mexican-origin youth

Internalizing symptoms, negative urgency, and coping motives: Potential pathways to alcohol consequences

OBJECTIVE

Building upon prior research, the present study tested coping motives as a mediator of relations between both negative urgency and internalizing symptoms (depression, anxiety, and stress), and alcohol-related consequences using longitudinal data. We also tested negative urgency as a moderator of prospective relations between specific internalizing symptoms and alcohol-related consequences.

METHOD

The study utilized data from a longitudinal study of young adults (N = 448; Mage = 22.27, SD = 1.25). Participants (56.5% male) were evaluated at baseline and at 12-month and 24-month follow-ups. Mood, impulsivity, coping motives, and alcohol consequences were assessed at baseline, and motives and consequences were assessed at follow-ups.

RESULTS

Prospective indirect effects of internalizing symptoms and negative urgency on alcohol consequences through coping motives were not observed. However, cross-sectional post hoc analyses indicated that higher levels of internalizing and negative urgency were indirectly associated with greater alcohol consequences through coping motives, with similar patterns observed for depression, anxiety, and stress. Although support was found for mediated effects in the cross-sectional model, no evidence was found for negative urgency moderating the impact of internalizing, stress, anxiety, or depression on alcohol consequences in either cross-sectional or longitudinal models.

CONCLUSION

Findings provide cross-sectional but not longitudinal support for coping motives as a potential mechanism through which a broad range of internalizing symptoms are associated with alcohol consequences. Findings did not support interactions between negative urgency and internalizing symptoms. The results highlight the need for further exploration of mediated effects using ecological momentary assessments. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Development of Comorbid Alcohol Use and Depressive Symptoms During Late Adolescence: Examining the Roles of Emotion Regulation and Gender Differences

Depression and alcohol use are highly comorbid, and often emerge during adolescence. Depressive symptoms may precede alcohol use, via the self-medication pathway, or alcohol use may precede depressive symptoms, via the alcohol induced disruption pathway. Yet little is known about other risks for developing comorbidity via either path. The present study hypothesized that poor cognitive and physiological emotion regulation (ER) are risk factors implicated in the development of comorbid depression and alcohol use during late adolescence. Participants were 229 (113 girls) Mexican-origin youth who reported on depressive symptoms and alcohol use at ages 17 (Time 1) and 19 years (Time 2). At age 17, cognitive reappraisal (CR), an adaptive ER strategy, and baseline respiratory sinus arrhythmia (RSA), a physiological index of ER capacity, were assessed. CR, RSA and gender were examined as predictors and moderators of the developing comorbidity of alcohol use and depression in cross-lagged panel models. Lower use of CR was concurrently associated with more depressive symptoms at age 17 and predicted greater depression at age 19. Age 17 alcohol use predicted age 19 depressive symptoms for boys. Lower RSA at age 17 also predicted more depressive symptoms at age 19 for boys. Neither CR nor RSA moderated the predicted relations between depression and alcohol use. Findings supported the alcohol induced disruption model of comorbidity for boys, and showed that poor cognitive and physiological ER increased risk for exacerbating depressive symptoms in late adolescence.

Trajectories of polysubstance use: Are past-year internalizing and externalizing problems associated with trajectories of polysubstance use over time?

OBJECTIVE

Polysubstance use among adults has been a public health concern in the U.S. and is associated with adverse consequences. This study aimed to identify the longitudinal trajectory of polysubstance use and test whether internalizing and externalizing problems predict it.

METHODS

Data of adults aged 18 and older (N = 15076) were extracted from the Waves 1-5 Population Assessment of Tobacco and Health Study (2013-2019). Group-Based Trajectory Modeling was performed to identify the trajectory of polysubstance use. Examined substances included use of cigarettes, e-cigarettes, excessive alcohol, cannabis, painkillers, and cocaine in past 30 days from all waves. Weighted multinomial logistic regressions were conducted to investigate the associations between internalizing and externalizing problems and the trajectory of polysubstance use, controlling for demographic variables.

RESULTS

Five trajectory groups were identified: (1) No to minimal polysubstance use risk (45.6 %); (2) Polysubstance use-low risk (10.7 %); (3) Cigarette-leading polysubstance use-high risk (23.5 %); (4) Cigarette-cannabis co-leading polysubstance use-high risk (12.3 %); and (5) Cannabis-leading polysubstance use-high risk (7.8 %). Compared with Group 1, higher internalizing problems predicted the membership of Group 3 [Relative risk ratio (RRR) range: 1.07-1.17] and Group 4 (RRR range: 1.04-1.21). Compared with Group 1, higher externalizing problems predicted the membership of Group 5 (RRR range: 1.01-1.10).

CONCLUSIONS

Prevention efforts should consider internalizing problems and associated trajectories of high-risk polysubstance use (e.g., cigarette-leading and cigarette-cannabis co-leading) as well as externalizing problems and associated trajectories of high-risk polysubstance use (e.g., cannabis-leading), when designing interventions to prevent polysubstance use.

Associations between emotional reactivity to stress and adolescent substance use: Differences by sex and valence

Although stress is often related to substance use, it remains unclear whether substance use is related to individual differences in how adolescents respond to stress. Therefore the present study examined associations between substance use and daily emotional reactivity to stress within a year across adolescence. Adolescents (N = 330; Mage = 16.40, SD = 0.74 at study entry; n = 186 female; n = 138 Latine; n = 101 European American; n = 72 Asian American; n = 19 identifying as another ethnicity including African American and Middle Eastern) completed a longitudinal study, including three assessments between the 10th grade and 3-years post-high school. At each assessment, participants reported frequency of alcohol and cannabis use and the number of substances they had ever used. They also completed 15 daily checklists, in which they reported the number of daily arguments and their daily emotion. Multilevel models suggested that more frequent alcohol and cannabis use were related to attenuated positive emotional reactivity to daily stress (i.e., smaller declines in positive emotion on days when they experienced more arguments) for both male and female adolescents. Associations for negative emotional reactivity to stress varied by sex; more frequent alcohol use and use of more substances in one's lifetime were related to greater anxious emotional reactivity to stress among female adolescents, whereas more frequent alcohol and cannabis use and higher lifetime substance use were related to attenuated depressive emotional reactivity to stress among male adolescents. Taken together, substance use was related to emotional reactivity to daily stress within the same year during adolescence, although associations differed by valence and adolescent sex.

An Examination of Bidirectional Associations Between Alcohol Use and Internalizing Symptoms Among Adolescents During the COVID-19 Pandemic

PURPOSE

This study explores the bidirectional association between internalizing symptoms and alcohol use over three years of the COVID-19 pandemic to examine whether alcohol consumption is associated with higher internalizing symptoms in the next year and vice versa.

METHODS

We used linked data from a sample of 2,136 secondary school students who participated in three consecutive waves (2019-2020 [T1], 2020-2021 [T2], and 2021-2022 [T3]) of the Cannabis use, Obesity, Mental health, Physical activity, Alcohol use, Smoking, and Sedentary behaviour study during the pandemic. A random-intercept cross-lagged panel model was used to characterize reciprocal linear relations between internalizing symptoms and alcohol use.

RESULTS

The findings suggest that students who reported higher levels of alcohol use at T1 experienced increased levels of depression and anxiety in the subsequent year (T2). However, this association was not observed from T2 to T3. Throughout the three-year period, depression and anxiety were not associated with later alcohol use. In males, alcohol use at T1 was a predictor of higher internalizing symptoms at T2 but not from T2 to T3.

DISCUSSION

These results suggest time-sensitive impacts and notable gender differences in the relationship between internalizing symptoms and alcohol use over the pandemic. Given the complexity of impacts, ongoing evaluation of the impact of the pandemic on youth health behaviours is necessary to elucidate these unfolding relationships, especially as the pandemic continues to affect various psychosocial risk factors.

Neural Response to Social Exclusion Moderates the Link Between Adolescent Anxiety Symptoms and Substance Use

BACKGROUND

Substance use (SU) typically increases from middle to late adolescence. Anxiety is one factor associated with greater SU, although variability in who uses substances remains. Some models suggest that brain-based susceptibility markers could reveal which adolescents are at a higher risk for psychopathology, but it is unknown whether these individual differences attenuate or accentuate the association between anxiety and elevated SU even if normative. This study addressed this gap by testing whether neural response to social exclusion moderates the association between anxiety symptoms and increased SU from middle to late adolescence.

METHODS

Participants were 181 Mexican-origin adolescents (48% female; 16-17 years old) who completed a social exclusion task during a functional magnetic resonance imaging scan and filled out questionnaires about their SU and anxiety symptoms. Analyses focused on neural response to social exclusion versus inclusion within 3 regions of interest and change in SU across 2 years.

RESULTS

Dorsal anterior cingulate cortex response to social exclusion, but not subgenual anterior cingulate cortex or anterior insula, moderated the relation between anxiety symptoms and SU, such that higher anxiety symptoms predicted a greater relative increase in SU only for those youth with a lower dorsal anterior cingulate cortex response to exclusion.

CONCLUSIONS

Blunted dorsal anterior cingulate cortex response to social exclusion may serve as a neural susceptibility marker of altered conflict monitoring or emotion regulation in middle adolescence that, in combination with high levels of anxious feelings, elevates the risk for onset of and/or increased SU by late adolescence. These findings have implications for designing targeted interventions to mitigate SU among adolescents.

Neural connectivity biotypes: associations with internalizing problems throughout adolescence

BACKGROUND

Neurophysiological patterns may distinguish which youth are at risk for the well-documented increase in internalizing symptoms during adolescence. Adolescents with internalizing problems exhibit altered resting-state functional connectivity (RSFC) of brain regions involved in socio-affective processing. Whether connectivity-based biotypes differentiate adolescents' levels of internalizing problems remains unknown.

METHOD

Sixty-eight adolescents (37 females) reported on their internalizing problems at ages 14, 16, and 18 years. A resting-state functional neuroimaging scan was collected at age 16. Time-series data of 15 internalizing-relevant brain regions were entered into the Subgroup-Group Iterative Multi-Model Estimation program to identify subgroups based on RSFC maps. Associations between internalizing problems and connectivity-based biotypes were tested with regression analyses.

RESULTS

Two connectivity-based biotypes were found: a Diffusely-connected biotype (N = 46), with long-range fronto-parietal paths, and a Hyper-connected biotype (N = 22), with paths between subcortical and medial frontal areas (e.g. affective and default-mode network regions). Higher levels of past (age 14) internalizing problems predicted a greater likelihood of belonging to the Hyper-connected biotype at age 16. The Hyper-connected biotype showed higher levels of concurrent problems (age 16) and future (age 18) internalizing problems.

CONCLUSIONS

Differential patterns of RSFC among socio-affective brain regions were predicted by earlier internalizing problems and predicted future internalizing problems in adolescence. Measuring connectivity-based biotypes in adolescence may offer insight into which youth face an elevated risk for internalizing disorders during this critical developmental period.

Early life mental health and problematic drinking in mid-adulthood: evidence from two British birth cohorts

PURPOSE

Accumulating evidence suggests that externalising problems are consistently associated with alcohol use behaviours, but findings are inconsistent regarding the role of internalising problems. We investigate whether externalising and internalising problems are associated with problematic drinking in mid-adulthood, and whether potential associations are modified by age, sex and cohort.

METHODS

The National Child Development Study (NCDS58, n = 17,633) and 1970 British Cohort Study (BCS70, n = 17,568) recruited new-borns in Great Britain in a single week in 1958 and 1970. Mental health was assessed with the Rutter Behaviour Questionnaire at ages 7, 11, and 16 in NCDS58 and ages 5, 10 and 16 in BCS70. Problematic drinking was measured with the CAGE questionnaire at age 33 in NCDS58 and age 34 in BCS70, and the AUDIT scale at age 44/45 in NCDS58 and age 46 in BCS70. Latent scores of externalising and internalising problems were added chronologically into lagged logistic regression models.

RESULTS

Externalising and internalising problems were associated in opposite directions with problematic drinking in mid-adulthood. Externalising was a risk factor (OR [95% CI] ranging from 1.06 [1.03, 1.10] to 1.11 [1.07, 1.15] for different ages), and internalising was a protective factor (OR [95% CI] ranging from 0.95 [0.92, 0.99] to 0.90 [0.86, 0.94] for different ages). Associations between early life mental health and mid-adulthood problematic drinking did not differ by developmental timing but were stronger in males.

CONCLUSION

Our study provides new insights on links of externalising and internalising difficulties with alcohol use and has implications for public policy in the UK.

Alcohol consumption and dependence is linked to the extent that people experience need satisfaction while drinking alcohol in two Aboriginal and Torres Strait Islander communities

BACKGROUND

Unhealthy alcohol use is a key concern for Aboriginal and Torres Strait Islander ('Indigenous Australian') communities. Due to systematic disadvantage and inter-generational trauma, Indigenous Australians may be less likely to have satisfied basic psychological needs (autonomy, competence, and relatedness). When people are need-thwarted, they may engage in compensatory behaviours to feel better in the short-term. We explore the relationship between perceived basic psychological needs satisfaction and alcohol consumption use among Indigenous Australians. Better understanding the functions that alcohol may play for some Indigenous Australian drinkers may aid communities, clinicians, and policy makers in improving programs for reducing drinking-related harms.

METHODS

We performed a cross-sectional survey of Indigenous Australians (aged 16 years or older) living in two South Australian communities. Participants were eligible if they had consumed any alcohol in the past 12 months. Spearman correlations and linear regressions were used to determine if feeling more autonomous, competent, and related to others (need satisfied) while drinking, was linked to alcohol consumption and dependence.

RESULTS

Controlling for participant demographics, reporting feeling need satisfied while drinking was linked to drinking more alcohol per day, reporting more frequent symptoms of alcohol dependence, spending more money on alcohol, and scoring higher on the AUDIT-C.

CONCLUSIONS

Unhealthy drinking may partly stem from attempts to satisfy basic psychological needs. Programs which support Indigenous Australians to meet basic psychological needs could reduce attempts to meet psychological needs through alcohol consumption.

Adolescent Substance Use and the Brain: Behavioral, Cognitive and Neuroimaging Correlates

Adolescence is an important ontogenetic period that is characterized by behaviors such as enhanced novelty-seeking, impulsivity, and reward preference, which can give rise to an increased risk for substance use. While substance use rates in adolescence are generally on a decline, the current rates combined with emerging trends, such as increases in e-cigarette use, remain a significant public health concern. In this review, we focus on the neurobiological divergences associated with adolescent substance use, derived from a cross-sectional, retrospective, and longitudinal studies, and highlight how the use of these substances during adolescence may relate to behavioral and neuroimaging-based outcomes. Identifying and understanding the associations between adolescent substance use and changes in cognition, mental health, and future substance use risk may assist our understanding of the consequences of drug exposure during this critical window.

Bidirectional relationships in the development of internalising symptoms and alcohol use in adolescence

INTRODUCTION AND AIMS

Previous literature has demonstrated an inconsistent relationship between alcohol use and internalising symptoms (anxiety, depression) in youth. This study aimed to clarify this link examining the bidirectional relationships between internalising symptoms and alcohol use in a community sample of adolescents, taking into account the effect of gender and externalising symptoms.

DESIGN AND METHODS

Parallel latent growth models were run to prospectively explore the bidirectional relationships between internalising symptoms and alcohol use when assessed five times over 2 years, among 1557 (67% female) adolescents from age 13.5 years.

RESULTS

Results showed that higher initial levels of internalising symptoms predicted increasing alcohol use frequency; however, this association was no longer significant once externalising symptoms and gender were accounted for. No bidirectional associations between internalising symptoms and alcohol use were found.

DISCUSSION AND CONCLUSIONS

This study adds to the literature examining the bidirectional relationships between internalising symptoms and alcohol use in adolescence. Findings highlight the importance of both gender and externalising symptoms in the development of this type of comorbidity and may help explain discrepant findings in the existing literature. Future prevention efforts for internalising problems and alcohol use should consider gender and externalising symptoms.

Risk Factors Associated with Alcohol Use in Early Adolescence among American Inner-City Youth: A Longitudinal Study

Background: Early alcohol use is associated with an increased risk for later alcohol dependence, as well as social and mental health problems. In this study, we investigate the risk factors (internalizing and externalizing behaviors) associated with early alcohol consumption over a period of 1 year, and examine whether the association is sex-specific. Methods: U.S. inner-city adolescents (N = 1785, Mean age = 12.11) were assessed and reassessed in the sixth and seventh grades (Mean age = 13.10). Self-reported information was obtained on the lifetime level of alcohol consumption, internalizing (depression, anxiety and posttraumatic stress [PTS]), and externalizing behaviors (sensation seeking, conduct problems and affiliation with delinquent peers). Associations between the variables were examined using structural equation modeling (SEM). Results: In an adjusted SEM analysis drinking by the sixth grade was primarily associated with externalizing behaviors, whereas PTS was linked to lower levels of alcohol consumption. In addition, alcohol consumption and greater externalizing behaviors by the sixth grade predicted higher alcohol consumption by the seventh grade, whereas anxiety and African American ethnicity were associated with less alcohol consumption. No sex differences were found in the association between internalizing and externalizing behaviors and drinking. However, in the adjusted SEM analysis female sex predicted higher lifetime consumption by the seventh grade. Conclusion: Sensation seeking behavior, conduct problems and affiliation with delinquent peers should be regarded as risk factors and taken into consideration when planning prevention efforts in order to decrease alcohol use in early adolescence.

Internalizing symptoms and cannabis and alcohol use: Between- and within-person risk pathways with coping motives

OBJECTIVE

To test reciprocal associations among internalizing symptoms (depression and social anxiety), using alcohol and cannabis to cope, and use-related problems.

METHOD

The study utilized a community sample (N = 387, 55% female; majority non-Hispanic Caucasian (83.1%) or African American (9.1%) and a longitudinal design that spanned 17 to 20 years of age, and distinguished within- and between-person associations using latent curve models with structured residuals.

RESULTS

Reciprocal prospective within-person associations were supported for alcohol, such that elevated depression symptoms were associated with increased alcohol coping motivates 1 year later, which, in turn, was associated with subsequent increased depression symptoms. Bidirectional associations were not supported for social anxiety, although high levels of social anxiety were associated with elevated levels of coping drinking 1 year later. Cannabis coping motives were associated with exacerbation of depression, but not social anxiety symptoms, 1 year later. Between- and within-person contemporaneous associations suggested that depression and social anxiety were more strongly associated with coping than social/enhancement motives, and that coping motives were associated with use-related problems.

CONCLUSION

Findings suggest that alcohol coping motivates exacerbate rather than ameliorate depression symptoms, which, in turn, leads to greater reliance on alcohol to cope. There was more consistent support for associations with substance use-related problems for depression than for social anxiety. Both between- and within-person associations may be useful for identifying targets and timing of coping-oriented interventions. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Parenting Practices and Adjustment Profiles among Latino Youth in Rural Areas of the United States

On average, Latino adolescents in the United States (U.S.) are at an elevated risk for developing internalizing symptoms, externalizing behaviors, and engaging in binge drinking. Latino youth in rural U.S. contexts may be particularly at risk. Parent–adolescent relationships may be associated with each of these indicators of maladjustment, as well as the co-occurrence of these issues. In the current study, adjustment profiles based on internalizing symptoms, externalizing behaviors, and binge drinking among 198 Latino adolescents (Mage = 15.90, SD = 1.47) living in rural areas of the United States were examined. Further, the association of adjustment profiles with parental behavioral involvement, parental monitoring, and familial ethnic socialization was tested. Four adjustment profiles emerged from a cluster analysis (i.e., low risk, internalizing risk, externalizing risk, co-occurring risk). Results indicated that adolescents in the co-occurring risk profile reported the lowest levels of parental monitoring compared to the other three profiles, lower familial ethnic socialization compared to the low risk and internalizing risk profiles, and lower parental behavioral involvement compared to the internalizing risk profile. The findings have implications for family-based, culturally informed interventions to encourage positive adjustment among Latino adolescents in rural areas of the United States.

Associations of child and adolescent anxiety with later alcohol use and disorders: a systematic review and meta-analysis of prospective cohort studies

BACKGROUND AND AIMS

Despite a wealth of literature, the relationship between anxiety and alcohol use remains unclear. We examined whether (a) child and adolescent anxiety is positively or negatively associated with later alcohol use and disorders and (b) study characteristics explain inconsistencies in findings.

DESIGN AND SETTING

We conducted a systematic review of 51 prospective cohort studies from 11 countries. Three studies contributed to a meta-analysis. We searched PubMed, Scopus, Web of Science and PsycINFO databases, and studies were included if they met the following criteria: English language publication, human participants, anxiety exposure (predictor variable) in childhood or adolescence and alcohol outcome at least 6 months later.

PARTICIPANTS

Study sample sizes ranged from 110 to 11 157 participants. Anxiety exposure ages ranged from 3 to 24 years, and alcohol outcome ages ranged from 11 to 42 years.

MEASUREMENTS

Ninety-seven associations across 51 studies were categorized by anxiety exposure (generalized anxiety disorder, internalizing disorders, miscellaneous anxiety, obsessive compulsive disorder, panic disorder, separation anxiety disorder, social anxiety disorder and specific phobias) and alcohol use outcome (drinking frequency/quantity, binge drinking and alcohol use disorders).

FINDINGS

The narrative synthesis revealed some evidence for a positive association between anxiety and later alcohol use disorders. Associations of anxiety with later drinking frequency/quantity and binge drinking were inconsistent. Type and developmental period of anxiety, follow-up duration, sample size and confounders considered did not appear to explain the discrepant findings. The meta-analysis also showed no clear evidence of a relationship between generalized anxiety disorder and later alcohol use disorder (odds ratio = 0.94, 95% confidence interval = 0.47-1.87).

CONCLUSIONS

Evidence to date is suggestive, but far from conclusive of a positive association between anxiety during childhood and adolescence and subsequent alcohol use disorder.

A longitudinal study of reciprocal risk between mental and substance use disorders among Mexican youth

OBJECTIVE

Cross-sectional studies have documented a large co-occurrence of alcohol, drug and tobacco use and disorders with mood, anxiety and disruptive behavior disorders. Longitudinal research among adolescents is much more limited and inconsistent. We tested for possible prospective associations of alcohol, drug, and tobacco use and disorders with an array of anxiety, mood and disruptive behavior disorders from adolescence to early adulthood.

METHODS

We estimated prospective associations from a follow-up conducted in 2013 (n = 1071; ages 19-26) of the original Mexican Adolescent Mental Health Survey conducted in 2005 (ages 12-17), by using Relative Risk (RR) estimates.

RESULTS

Prior drug and tobacco use and disorders had small to modest associations with subsequent mood and disruptive behavior disorders (significant RR ranging from 1.42 to 3.30). Inversely, prior mood (RR = 1.54), anxiety (RR = 1.20) and disruptive behavior disorders (RR = 1.61) increased risk of any subsequent substance use disorder. Prior anxiety disorders increased the risk of drug use disorder (RR = 1.69) and prior disruptive behavior disorders increased risk of incident alcohol (RR = 1.70) and drug use (RR = 2.61) disorders. Attention deficit/hyperactivity disorder, in particular, was related to incident alcohol (RR = 2.08), drug (RR = 3.66), nicotine dependence (RR = 2.57) and any substance use disorders (RR = 2.18).

DISCUSSION

We found limited longitudinal evidence of bidirectional influences between substance use disorders and mood, anxiety and disruptive behavior disorders with effect sizes that were modest at most under all circumstances. Mechanisms for these complex relationships need to be addressed in future research.

[Internalizing and externalizing behavior problems and substance use in adolescence]

This study investigated the relationship between externalizing behavior problems (EBP), internalizing behavior problems (IBP), and combined externalizing/internalizing behavior problems (EIBP) in early adolescence (11 years) and substance use (alcohol, tobacco, and illegal drugs) at 15 years, using data from the 1993 Pelotas (Brazil) birth cohort. Behavior problems were assessed with the Strengths and Difficulties Questionnaire (SDQ), applied to mothers when their children were 15 years old. Substance use was assessed with a self-applied confidential questionnaire for the adolescent. The association between behavior problems and substance use was analyzed with Poisson regression with robust adjustment of variance. After adjusting for confounding, adolescents with EBP showed higher risk of alcohol abuse (RR = 1.74, 95%CI: 1.21; 2.50) and experimentation (RR = 1.78, 95%CI: 1.42; 2,23) and tobacco use in the previous 30 days (RR = 2.38, 95%CI: 1.64; 3.45). Adolescents with IBP showed greater risk of having tried tobacco (RR = 1.54, 95%CI: 1.22; 1.93) and of having used tobacco products in the previous 30 days (RR = 1.92, 95%CI: 1.31; 2.83). Adolescents with EIBP showed greater risk of trying (RR = 2.24, 95%CI: 1.57; 3.21) and consuming tobacco products in the previous days (RR = 3.01, 95%CI: 1.63; 5.56), and lower risk of having tried alcohol at 15 years of age (RR = 0.72, 95%CI: 0.55; 0.94). Public health measures aimed at reducing behavior problems in early adolescence can help reduce tobacco and alcohol consumption at 15 years.

Pediatrician and Behavioral Clinician-Delivered Screening, Brief Intervention and Referral to Treatment: Substance Use and Depression Outcomes

PURPOSE

Early intervention for adolescent substance use and mental health problems may mitigate potential harm. We examined patient outcomes from a pragmatic trial of two modalities of delivering screening, brief intervention, and referral to treatment (SBIRT) and usual care (UC) in pediatric primary care.

METHODS

All clinic pediatricians (n = 52) were randomized to three arms: (1) pediatrician-only, in which pediatricians were trained to deliver SBIRT; (2) embedded behavioral clinician (BC), in which pediatricians were trained to refer eligible adolescents to a BC who administered SBIRT; and (3) UC. Using electronic health record data, changes in past year substance use and depression symptoms between the index visit and next screening visit were examined across treatment arms.

RESULTS

Among patients who endorsed substance use and/or depression symptoms or were eligible for further assessments, brief interventions, and referrals based on clinician assessment at the index visit, 648 patients (mean age = 15.2 [standard deviation = 1.2]) were rescreened at a follow-up visit between 6 months and 2 years later. Among all patients, self-reported substance use rates did not differ over time or across arms, and depression symptoms increased over time. The embedded BC arm had lower odds of having depression symptoms at follow-up than the physician-only arm, and lower odds than the UC arm although not significant; we found no differences between the pediatrician-only and UC arms.

CONCLUSIONS

The increase in depression symptoms over time highlights this population's vulnerability and the importance of developing appropriate interventions. An embedded BC in pediatric primary care trained in SBIRT may benefit patients with depression symptoms.

The Prospective Association Between Internalizing Symptoms and Adolescent Alcohol Involvement and the Moderating Role of Age and Externalizing Symptoms

BACKGROUND

As predicted by self-medication theories that drinking is motivated by a desire to ameliorate emotional distress, some studies find internalizing symptoms (e.g., anxiety, depression) increase risk of adolescent drinking; however, such a risk effect has not been supported consistently. Our prior work examined externalizing symptoms as a potential moderator of the association between internalizing symptoms and adolescent alcohol use to explain some of the inconsistencies in the literature. We found that internalizing symptoms were protective against early adolescent alcohol use particularly for youth elevated on externalizing symptoms (a 2-way interaction). Our sample has now been followed for several additional assessments that extend into young adulthood, and the current study tests whether the protective effect of internalizing symptoms may change as youth age into young adulthood, and whether this age-moderating effect varied across different clusters of internalizing symptoms (social anxiety, generalized anxiety, and depression). Internalizing symptoms were hypothesized to shift from a protective factor to a risk factor with age, particularly for youth elevated on externalizing symptoms.

METHODS

A community sample of 387 adolescents was followed for 9 annual assessments (mean age = 12.1 years at the first assessment and 55% female). Multilevel cross-lagged 2-part zero-inflated Poisson models were used to test hypotheses.

RESULTS

The most robust moderating effects were for levels of alcohol use, such that the protective effect of all internalizing symptom clusters was most evident in the context of moderate to high levels of externalizing problems. A risk effect of internalizing symptoms was evident at low levels of externalizing symptoms. With age, the risk and protective effects of internalizing symptoms were evident at less extreme levels of externalizing behavior. With respect to alcohol-related problems, findings did not support age moderation for generalized anxiety or depression, but it was supported for social anxiety.

CONCLUSIONS

Findings highlight the importance of considering the role of emotional distress from a developmental perspective and in the context of externalizing behavior problems.
