The role of substance use coping in linking depression and alcohol use from late adolescence through early adulthood

Coping Strategies in Patients with Bipolar Disorder (BD) and Major Depressive Disorder (MDD) and Their Correlation with Clusters of Psychiatric Symptoms

Background: Adjustment to stress requires the involvement of coping strategies. Using maladaptive coping strategies may precipitate the onset or recurrence of psychiatric disorders. On the other hand, the illness itself may alter the coping mechanisms of an individual. This study aims to identify the coping strategies in patients with bipolar disorder (BD) and major depressive disorder (MDD) and determine the correlation between coping strategies and clusters of psychiatric symptoms. Material and Methods: Socio-demographic and clinical data were analyzed for 30 inpatients with BD and 30 inpatients with MDD. The SCL-90 questionnaire and COPE inventory were filled in by the participants. Results: Compared to the general population, the patients with BD had lower scores for functional coping strategies and higher scores for one dysfunctional coping strategy. The patients with MDD had lower scores for all active functional and two passive functional coping strategies. By contrast, they presented higher scores on one passive functional and one dysfunctional coping strategy. Positive reinterpretation and growth were negatively correlated with somatization, depression, anxiety, interpersonal sensitivity, hostility, and psychoticism. Behavioral disengagement was positively correlated with depression, anxiety, somatization, interpersonal sensitivity, and psychoticism. Substance use was positively correlated with the number of episodes. Distinct coping mechanisms were associated with certain symptom clusters. Conclusions: Although dysfunctional coping strategies may predispose to psychiatric disorders, in our study, they appear to be state-dependent rather than trait-dependent.

Exploring Alcohol Use Expectancies as Mediators in the Relationship Between Psychological Stressors and Substance Use Among Youths Living with HIV in Uganda

We investigated the mediating role of alcohol use expectancies between three psychological/emotional states (depressive symptoms, hopelessness, and adverse childhood experiences (ACE)) and problematic alcohol and substance use among YLHIV in Uganda. We defined problematic substance use according to the National Institute on Drug Abuse (NIDA)-modified Alcohol, Smoking, and Substance Involvement Screening Test (NM-ASSIST) to derive a Substance Involvement (SI) score to identify participants' risk level. We grouped moderate and high risk into one category to represent 'problematic use' or use that would qualify as a substance use disorder. We tested the proposed mediation models using the PROCESS macro for mediation, moderation, and conditional process analysis version 4.1 for SPSS. We observed that higher scores for depressive symptoms, hopelessness, and ACE, were each associated with increased levels of global AUE (GAUE). However, mediation analyses revealed significant indirect effects of depressive symptoms (1.03, 95% CI 1.0002 to 1.0926), hopelessness (1.11, 95% CI 1.0172 to 1.3349), and ACE (1.08, 95% CI 1.0027 to 1.2695) on problematic substance use via GAUE. Also negative AUE (NAUE) significantly mediated the relationship between depressive symptoms, hopelessness, and ACE and problematic substance use. Our study highlights the significant role of GAUE and NAUE in mediating the relationship between ACE, depressive symptoms, hopelessness, and problematic substance use among YLHIV. The findings suggest that interventions targeting GAUE and NAUE and possibly providing effective coping mechanisms for managing depressive symptoms, hopelessness, and the impact of ACE may be crucial in reducing substance use among YLHIV.

A Brief Cognitive Behavioral Therapy-Based Digital Intervention for Reducing Hazardous Alcohol Use in South Korea: Development and Prospective Pilot Study

Background

Alcohol consumption is a leading cause of death and disability worldwide, associated with numerous acute and chronic medical conditions. Digital health interventions offer a promising solution to overcome barriers associated with traditional treatment methods, providing accessible, scalable, and cost-effective means to support individuals in reducing hazardous drinking.

Objective

This pilot study aims to evaluate the feasibility, acceptability, and preliminary efficacy of the Sober smartphone app in individuals with hazardous alcohol use.

Methods

This single-group, pre- and postpilot study included 20 participants with risky alcohol use, identified using the Alcohol Use Disorder Identification Test. Participants used the Sober app for 4 weeks, incorporating cognitive behavioral therapy-based interventions. Feasibility was assessed by study and session completion rates, acceptability by participant satisfaction and perceived usefulness, and preliminary efficacy by changes in alcohol consumption and psychiatric symptoms. Semistructured interviews with participants and clinicians provided qualitative perspectives on the app's usability, efficacy, and areas for improvement.

Results

Of the 20 enrolled participants, 17 completed the study. The app demonstrated high feasibility with an 85% (17/20) study completion rate, and 59% (10/17) completed all cognitive behavioral therapy sessions. Participants reported positive acceptability, with average satisfaction and usefulness ratings of 3.8 and 3.7 of 5, respectively. Preliminary efficacy outcomes showed significant improvements: abstinence days increased from 67% to 85% (z=-3.17; P=.002), heavy drinking episodes decreased from 3.3 to 1.9 (t16=-2.97; P=.003), and total alcohol consumption reduced from 456.8 to 195.9 mL (t16=3.16; P=.002). Alcohol Use Disorder Identification Test scores dropped from 17.5 to 10.7 (t16=4.51; P<.001). Additionally, depression (Patient Health Questionnaire-9) scores decreased from 5.8 to 4.4 (t16=2.91; P=.01), and anxiety (Generalized Anxiety Disorder-7) scores from 3.4 to 2.1 (z=-2.80; P=.005). No adverse events were reported. Qualitative analysis found participants valued daily logging but noted usability issues, while clinicians called for tailored goals, enhanced communication features, and age-specific content.

Conclusions

The mobile app Sober shows promise as an effective tool for reducing hazardous alcohol consumption and improving related psychiatric symptoms. The study demonstrated high feasibility and positive acceptability, with significant preliminary efficacy in reducing alcohol use. Qualitative findings provided actionable evidence for refining the app's usability and clinical integration. Further research through a randomized controlled trial is warranted to confirm these findings and optimize the app's features and content.

Depression, Drinking to Cope, and Alcohol Use Severity Among Latinos Who Drink: The Moderating Role of Sex

OBJECTIVES

The present study evaluated sex differences in the direct and indirect links between depressive symptoms, coping motives to drink, and alcohol use severity among Latinos who drink.

METHODS

A large and diverse panel sample of Latinos, who were strategically sampled to be reflective of the Latino demographics of the state of Texas, completed questionnaires assessing their depressive symptomatology, coping motives to drink, and alcohol use behaviors.

RESULTS

Direct effects were significant in hypothesized directions such that depressive symptoms was positively associated with both coping motives to drink and alcohol use severity, and drinking motives to cope were positively associated with alcohol use severity. Moderator analysis showed that, compared to Latina women, the association of depressive symptoms with both drinking to cope and alcohol use severity was significantly higher among Latino men. Regarding indirect effects, a moderated mediation analysis showed that the indirect effect of depressive symptoms on alcohol use severity through coping motives to drink was statistically significant for both Latino/a men and women; however, the index of moderated mediation showed that this indirect effect was significantly greater among Latino men.

CONCLUSION

Although both Latino/a men and women may consume alcohol and turn to alcohol to drink with negative affect associated with depressive symptoms, this process may be stronger among Latino men. Findings are discussed considering prior work and implications for practitioners.

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.

Negative Affect, Sensation Seeking, and Adolescent Substance Use Development: The Moderating Role of Executive Function

It is unknown how the Addictions Neuroclinical Assessment markers-negative affect, sensation seeking, and executive function-contribute to substance use development. This study examined whether associations of negative affect and sensation seeking with substance use vary by executive function. Participants were 167 adolescents (47% female) who participated annually for four years (Mage = 14.07, SDage = 0.54 at Time 1). There were within-person bidirectional associations between higher negative affect and higher substance use for adolescents with lower executive function. Adolescents with higher sensation seeking at age 14 exhibited increasing substance use trajectories from age 14 to 17, regardless of executive function level. Negative affect and substance use influence each other within individuals, whereas sensation seeking predicts substance use between individuals.

Do Symptoms of Depression Moderate the Links Between Reactive and Proactive Aggression and Frequency of Substance Use?

Youth substance use continues to be a public health concern, with both aggressive behavior and symptoms of depression commonly identified as risk factors for adolescent substance use. However, more research is needed to understand how proactive and reactive functions of aggression are uniquely associated with the frequency of use of specific substances and how these functions of aggression interact with symptoms of depression to contribute to substance use. To this end, the current study examined these associations in a sample of detained youth (N = 229; 80.7% Male). Results suggested that reactive aggression is uniquely associated with traditional cigarette, alcohol, and marijuana use, while proactive aggression is uniquely associated with prescription drug use. Further, although symptoms of depression did not uniquely contribute to the frequency of substance use, symptoms of depression moderate links between proactive aggression and frequency of traditional cigarette, alcohol, and prescription drug use such that proactive aggression is associated with increased frequency of use only when symptoms of depression are low. Findings suggest the need to consider functions of aggression when identifying risk for frequent substance use, as there may be distinct targets of intervention depending on the function of aggression.

Substance use and risk of suicide among adults who sought mental health and addiction specialty services through a centralised intake process in Nova Scotia: a cross-sectional study

OBJECTIVES

The objectives of this study are as follows: (1) to estimate the prevalence of suicide risk among individuals seeking mental health and addiction (MHA) services in Nova Scotia; (2) to examine the relationship between substance use and suicide risk among this population.

SETTING

MHA intake programme, a province-wide centralised intake process established in 2019 by the Department of Health and Wellness of Nova Scotia.

PARTICIPANTS

We included 22 500 MHA intake clients aged 19-64 years old who contacted MHA intake from 2020 to 2021.

PRIMARY OUTCOME MEASURES

During the intake assessment, clients were assessed for suicide risk (past suicide attempt, suicidal ideation during the interview or 2 weeks before the interview).

RESULTS

The lifetime prevalence of suicide attempt was 25.25% in the MHA clients. The prevalence of mild and moderate/high suicide risk was 34.14% and 4.08%, respectively. Clients who used hallucinogens had the highest prevalence of mild and moderate/high suicide risk (61.3% and 12.9%, respectively), followed by amphetamine/methamphetamine (47.6% and 13.3%, respectively) and sedative/hypnotics (47.2% and 8.9%, respectively) users. Stimulant (aOR=1.84, 95% CI 1.23 to 2.75) and hallucinogen (aOR=3.54, 95% CI 1.96 to 6.43) use were associated with increased odds of moderate/high suicide risk compared with denying current use. Additionally, alcohol (aOR=1.17, 95% CI 1.06 to 1.30) and tobacco (aOR=1.20, 95% CI 1.10 to 1.30) use were associated with increased odds of mild suicide risk.

CONCLUSION

Suicide behaviours were prevalent among clients seeking MHA services. Substance use is an important factor associated with suicide risk in this population. This result underscored the importance of considering substance use patterns when assessing suicide risk and highlighted the need for targeted interventions and preventive measures for individuals engaging in substance use. Future interventional studies are needed to identify and evaluate effective strategies for reducing substance use and suicide risk among clients of MHA central intake.

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.

Generational Immigration Status Modifies the Association Between Psychosocial Distress and Substance Use Among Alternative High School Students

PURPOSE

Alternative high schools (AHS) are designed to provide individualized education, more flexible scheduling, and smaller class sizes for students referred out of traditional high school. AHS students report higher levels of substance use (SU) and face disproportionately higher levels of trauma and toxic stress than their traditional high school peers. We sought to examine whether generational immigration (GenIm) status modifies the association of mental health and SU among AHS students using a longitudinal study of 1,060 Southern California AHS students.

METHODS

Subscales from the 21-item Depression Anxiety Stress Scale were administered. Effect modification was examined by GenIm status defined as first generation (born outside of the United States), second generation (born in the United States with a parent born outside the United States), or third generation (born in the United States with US-born parent(s)). Main outcomes included the number of times different substances were used in the past year over a 3-year period.

RESULTS

Multilevel, negative binomial, covariate-adjusted latent growth curve models generated incidence rate ratios (IRRs) and 95% confidence intervals (CIs) of the time-varying association between depression, anxiety, or stress and the use of cigarettes, e-cigarettes, cigars, alcohol, or marijuana. Multiple-group models examined effect modification by GenIm status.

DISCUSSION

The link between mental health and SU was stronger among first- and second-generation students than third-generation students. For example, a one-unit increase in stress relative to the average stress of students from the same school was associated with an increase in the rate of e-cigarette use among first-generation (IRR = 2.03, 95% CI = 1.07-3.85), second-generation (IRR = 2.25, 95% CI = 1.86-2.72), and third-generation (IRR = 1.68, 95% CI = 1.31-2.16) students. Effective strategies tailored to subgroups of AHS students are needed to counter disparities between traditional and alternative school systems that may contribute to long-term trajectories of SU.

Association between Current Substance Use, Healthy Behaviors, and Depression among Ukrainian College Students

Depression is a pervasive issue among college students worldwide, yet there is a significant gap in the literature regarding its prevalence and coping strategies in the Ukrainian context. The present study aims to fill this gap by investigating how substance use and health-promoting behaviors relate to depressive symptoms among Ukrainian college students. Health-promoting behaviors are an important strategy to prevent depression, whereas substance use can contribute to depression or make it harder to manage. Given the substantial psychosocial problems and stressors related to the ongoing war in Ukraine and the limited availability of mental health services for college students, it is important to understand how we can encourage college students to keep themselves mentally healthy. A cross-sectional study was conducted among college students on 10 campuses in 2018. Almost 16% of participants met a cut-off for depression. Female students and those who were older reported significantly higher depressive symptoms. Participants were more likely to report depressive symptoms if they were more often involved with alcohol and cannabis use, were older, and engaged in fewer health-promoting behaviors. Tobacco use was not significantly associated with depressive symptoms. Our findings suggest a moderate prevalence of depressive symptoms in our study population. We recommend implementing balanced public health interventions that address risk factors (such as substance use) while also promoting protective behaviors and can be tailored to the specific cultural and environmental context of the region.

Serotonergic dysfunction may mediate the relationship between alcohol consumption and Alzheimer's disease

The impact of Alzheimer's disease (AD) and its related dementias is rapidly expanding, and its mitigation remains an urgent social and technical challenge. To date there are no effective treatments or interventions for AD, but recent studies suggest that alcohol consumption is correlated with the risk of developing dementia. In this review, we synthesize data from preclinical, clinical, and epidemiological models to evaluate the combined role of alcohol consumption and serotonergic dysfunction in AD, underscoring the need for further research on this topic. We first discuss the limitations inherent to current data-collection methods, and how neuropsychiatric symptoms common among AD, alcohol use disorder, and serotonergic dysfunction may mask their co-occurrence. We additionally describe how excess alcohol consumption may accelerate the development of AD via direct effects on serotonergic function, and we explore the roles of neuroinflammation and proteostasis in mediating the relationship between serotonin, alcohol consumption, and AD. Lastly, we argue for a shift in current research to disentangle the pathogenic effects of alcohol on early-affected brainstem structures in AD.

Adverse Childhood Experiences, Coping and Resilience in Persons with Alcohol Use Disorder and Their Non-drinking Siblings in High-density Families: A Case-control Study

Background

Adverse childhood experiences (ACEs) increase the odds of alcohol use disorder (AUD).

Aim

To study the ACEs, coping, and resilience in persons with AUD and their non-drinking siblings from high-density families.

Methods

The study used a case-control study design. Using purposive sampling, 135 participants were selected; the sample consists of persons with AUD (n = 45), non-drinking siblings (n = 45), and healthy controls (n = 45), selected from out-patient and in-patient services from a government-run de-addiction centre in Bengaluru. Individuals were administered an ACEs questionnaire, Brief-COPE, and Connor-Davison Resilience scale. Descriptive statistics, Friedman's test, and Bonferroni's post-hoc test, Binary Logistic Regression were used for analysis.

Results

ACEs, coping, and resilience significantly differ across the three groups. Persons with AUD and their non-drinking siblings are comparable in terms of ACEs and having dysfunctional family members. Non-drinking siblings and healthy controls have similar coping and resilience. None of the healthy controls had dysfunctional family members.

Conclusion

ACEs are more prevalent and more frequent in persons with AUD. Individuals with AUD showed higher avoidant coping and lower resilience than their non-drinking siblings and healthy controls. Early identification of ACEs and interventions to build resilience and coping strategies could prevent individuals from developing AUD in high-density families.

Estimates of Major Depressive Disorder and Treatment Among Adolescents by Race and Ethnicity

Importance

The COVID-19 pandemic has contributed to poorer mental health and a greater need for treatment. Nationally representative estimates of major depressive disorder (MDD) and mental health treatment among US adolescents during the pandemic are needed.

Objective

To estimate MDD prevalence among adolescents, evaluate mental health treatment use among adolescents with MDD, and assess differences by race and ethnicity.

Design, Setting, and Participants

This cross-sectional analysis of the nationally representative 2021 National Survey on Drug Use and Health included noninstitutionalized US adolescents between the ages of 12 and 17 years (n = 10 743). Analytic weights were applied to all rates and model estimates to be nationally representative and account for sample design and survey nonresponse. Data were collected from January 14 to December 20, 2021, and analyzed from February 11 to April 3, 2023.

Exposures

Self-reported race and ethnicity.

Main Outcomes and Measures

Dichotomous outcomes of MDD as defined by the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition), MDD-specific mental health treatment, any type of mental health treatment, telehealth visits, and delays in mental health treatment.

Results

The sample included 10 743 adolescents (51.1% male). Self-reported race and ethnicity included 5.1% Asian, 14.1% Black, 23.3% Latinx, 51.2% White, and 6.3% more than 1 race. Ages were evenly distributed: 34.0% aged 12 to 13 years; 33.3% aged 14 to 15 years; and 32.7% aged 16 to 17 years. Adolescents of more than 1 race or ethnicity had the highest MDD rate (26.5%). Compared with White adolescents, the lowest rates of any MDD treatment overall were found among Latinx adolescents (29.2% [95% CI, 22.2%-36.2%]) and those of more than 1 race or ethnicity (21.1% [95% CI, 11.6%-30.7%]). Similar results were found for treatment by any clinician (Latinx, 25.6% [95% CI, 18.8%-32.4%]; >1 race or ethnicity, 19.1% [95% CI, 9.7%-28.6%]), treatment by a mental health specialist (Latinx, 22.9% [95% CI, 16.9%-28.9%]; >1 race or ethnicity, 16.7% [95% CI, 7.1%-26.3%]), treatment by a nonspecialist clinician (Latinx, 7.3% [95% CI, 3.3%-11.3%]; >1 race or ethnicity, 4.8% [95% CI, 1.9%-7.7%]), and use of any psychotropic medication prescription (Latinx, 11.6% [95% CI, 7.3%-15.9%]; >1 race or ethnicity, 8.3% [95% CI, 2.8%-13.7]). Compared with White adolescents, Black adolescents had lower rates of MDD treatment by any clinician (31.7% [95% CI, 23.7%-39.8%]) and by nonspecialist clinicians (8.4% [95% CI, 3.8%-13.2%]) and experienced lower prescription rates for any psychotropic medication (12.6 [95% CI, 4.6%-20.6%]). Asian (16.0% [95% CI, 5.0%-27.2%]) and Latinx (17.8% [95% CI, 12.6%-23.0%]) adolescents had lower rates of virtual mental health treatment compared with White adolescents. Black (19.1% [95% CI, 14.1%-24.2%]) and Latinx (17.9% [95% CI, 15.0%-21.1%]) adolescents had lower rates of appointments transition to telehealth, while Black adolescents (14.1% [95% CI, 10.7%-17.4%]) experienced delays getting their prescriptions.

Conclusions and Relevance

During the first full calendar year of the pandemic, approximately 1 in 5 adolescents had MDD, and less than half of adolescents who needed treatment had any mental health treatment. Adolescents in racial and ethnic minority groups, particularly Latinx, experienced the lowest treatment rates. Federal policy should target adolescents as a whole, and minority populations in particular, to ensure equitable treatment access. Efforts should consider the social, racial, ethnic, and cultural determinants of health.

Maternal Childhood Maltreatment, Internal Working Models, and Perinatal Substance Use: Is There a Role for Hyperkatifeia? A Systematic Review

The parent-infant relationship is critical for socioemotional development and is adversely impacted by perinatal substance use. This systematic review posits that the mechanisms underlying these risks to mother-infant relationships center on 3 primary processes: (1) mothers' childhood maltreatment experiences; (2) attachment styles and consequent internal working models of interpersonal relationships; and (3) perinatal substance use. Further, the review considers the role of hyperkatifeia, or hypersensitivity to negative affect which occurs when people with substance use disorders are not using substances, and which drives the negative reinforcement in addiction. The authors performed a systematic review of articles (published 2000-2022) related to these constructs and their impact on mother-infant relationships and offspring outcomes, including original clinical research articles addressing relationships between these constructs, and excluding case studies, reviews, non-human animal studies, intervention studies, studies with fewer than 30% female-sex participants, clinical guidelines, studies limited to obstetric outcomes, mechanistic/biological studies, and studies with methodological issues precluding interpretation. Overall 1844 articles were screened, 377 were selected for full text review, and data were extracted from 157 articles. Results revealed strong relationships between mothers' childhood maltreatment experiences, less optimal internal working models, and increased risk for perinatal substance use, and importantly, all of these predictors interacted with hyperkatifeia and exerted a marked impact on mother-infant relationships with less data available on offspring outcomes. These data strongly support the need for future studies addressing the additive impact of maternal childhood maltreatment experiences, suboptimal internal working models, and perinatal substance use, with hyperkatifeia as a potential moderator, and their interacting effects on mother-infant socioemotional outcomes.

The Ongoing Mental Health Plight of Depressed College Students: Clinical Recommendations and the Importance of Early Screening and Detection

The COVID-19 pandemic disrupted the lives of college students. The psychological distress from the pandemic increased risk for provisional rates of Major Depression Disorder (MDD) during an already crucial developmental period. Using an online survey, participants were assessed for a provisional diagnosis of MDD using a validated screening tool, along with Generalized Anxiety Disorder (GAD) and psychosocial correlates. Findings showed a significant increase in the prevalence of MDD, and significant differences in social support, loneliness, substance use, GAD and suicidality were identified. Early screening and detection for potential MDD symptoms can reduce the severity, duration, and reoccurrence of future MDD episodes for college students.

Coping strategies as mediating mechanisms between adolescent polysubstance use classes and adult alcohol and substance use disorders

Adolescent polysubstance use is a robust predictor of substance use in adulthood and can be exacerbated by poor coping with stress over time. We examined whether latent classes of adolescents' polysubstance use predicted alcohol use disorder and substance use disorder diagnoses in adulthood via multiple stress coping strategies. Self-reported frequency of past 3-month alcohol, tobacco, and marijuana use in 792 adolescents (aged 16/17) were used to form latent classes of polysubstance use. Self-reported aggressive, reactive, substance use and cognitive coping strategies (ages 18/19, 22/23, 23/24) were examined as multiple mediators of polysubstance use classes and alcohol use disorder and substance use disorder in adulthood (age 26/27) controlling for demographic covariates. Latent class analysis resulted in High, Experimental, and Low polysubstance use classes. Those in high and experimental polysubstance use classes, compared to those in the low polysubstance use class, had greater use of aggressive and reactive coping strategies, which respectively predicted greater substance use disorder and alcohol use disorder in adulthood. Across all comparisons (high vs low, experimental vs low, and high vs experimental), higher polysubstance use was associated with greater substance use coping, which predicted both alcohol and substance use disorder. Greater polysubstance use, even experimental use, in adolescence is a significant risk factor for developing alcohol use disorder and substance use disorder in adulthood and this occurs, in part, via maladaptive stress coping strategies.

Comparing the effectiveness of a brief intervention to reduce unhealthy alcohol use among adult primary care patients with and without depression: A machine learning approach with augmented inverse probability weighting

BACKGROUND

The combination of unhealthy alcohol use and depression is associated with adverse outcomes including higher rates of alcohol use disorder and poorer depression course. Therefore, addressing alcohol use among individuals with depression may have a substantial public health impact. We compared the effectiveness of a brief intervention (BI) for unhealthy alcohol use among patients with and without depression.

METHOD

This observational study included 312,056 adult primary care patients at Kaiser Permanente Northern California who screened positive for unhealthy drinking between 2014 and 2017. Approximately half (48%) received a BI for alcohol use and 9% had depression. We examined 12-month changes in heavy drinking days in the previous three months, drinking days per week, drinks per drinking day, and drinks per week. Machine learning was used to estimate BI propensity, follow-up participation, and alcohol outcomes for an augmented inverse probability weighting (AIPW) estimator of the average treatment (BI) effect. This approach does not depend on the strong parametric assumptions of traditional logistic regression, making it more robust to model misspecification.

RESULTS

BI had a significant effect on each alcohol use outcome in the non-depressed subgroup (-0.41 to -0.05, all ps < .003), but not in the depressed subgroup (-0.33 to -0.01, all ps > .28). However, differences between subgroups were nonsignificant (0.00 to 0.11, all ps > .44).

CONCLUSION

On average, BI is an effective approach to reducing unhealthy drinking, but more research is necessary to understand its impact on patients with depression. AIPW with machine learning provides a robust method for comparing intervention effectiveness across subgroups.
