Childhood Trauma and Two Stages of Alcohol Use in African American and European American Women: Findings from a Female Twin Sample

Coping motives as a mediator of the relationship between child maltreatment and substance use problems in south African adolescents

BACKGROUND

Evidence suggests that adults with a history of child maltreatment (CM) engage in substance misuse driven by 'coping motives': maladaptive beliefs that substances help them cope with negative emotions. However, the specificity of this risk pathway is under-researched in younger and non-Western cohorts.

OBJECTIVE

The present study aimed to determine whether coping motives play a distinct role compared to other motives for substance use in mediating the relationship between CM and problematic alcohol and marijuana use in a sample of South African adolescents.

PARTICIPANTS AND SETTING

A sample of 688 high school students (M age = 15.03 years; 62.5 % female) in Cape Town, South Africa, completed a cross sectional survey.

METHODS

Participants completed self-report measures of CM exposure, motives for using alcohol and marijuana (coping, enhancement, social and conformity), and alcohol and marijuana related problems. Participants who endorsed using alcohol (N = 180) or marijuana (N = 136) were included in analysis. A parallel mediation model was conducted for each substance (alcohol and marijuana, respectively) to assess which motives mediated the relationship between CM exposure and substance-related problems.

RESULTS

CM exposure predicted both alcohol-and marijuana related problems. The relationship between CM exposure and alcohol-related problems was partially mediated by coping motives (p < .001, 95%CI 0.028, 0.115) and, to a lesser extent, conformity motives (p < .01, 95%CI 0.001, 0.041), but not by social motives or enhancement motives. The relationship between CM exposure and marijuana-related problems was partially mediated by coping motives (p < .001, 95%CI 0.004, 0.037), but not by conformity, social or enhancement motives.

CONCLUSIONS

The findings support the importance of coping motives as a mediator between CM and problematic substance use across different substances of abuse in South African adolescents, and the role of conformity motives in problematic alcohol use. Future research should explore whether these findings hold across other sociocultural contexts, and the utility of interventions to address coping motives for substance use in adolescence.

Family history of substance problems among African Americans: Associations with drug use, drug use disorder, and prescription drug misuse

A family history of substance problems is a well-known risk factor for substance use and use disorders; however, much of this research has been conducted in studies with predominantly White subjects. The aim of this study was to examine the associations between family history density of substance problems and drug use, risk for drug use disorder, and prescription drug misuse in a sample of African American adults. Results indicate that family history density of substance problems increased the risk for all drug outcomes in the full sample. However, when subgroup analyses by gender were conducted, family history was not a risk factor among men for prescription drug misuse.

Patterns of alcohol use among middle school students in rural communities: Associations with community violence exposure

Stress-coping theory posits that exposure to stressors, such as community violence, increases risk for early alcohol initiation. The current study identified patterns of alcohol use in an ethnically diverse sample of early adolescents in rural communities, and examined relations between different forms of exposure to community violence and severity of adolescents' alcohol use patterns. Participants were 5011 middle school students (46.4% non-Hispanic White, 25.5% Latinx, and 13.4% Black; 50% female) living in rural communities in the southeastern United States. Latent class analysis identified subgroups that differed in their patterns of lifetime and past 30-day alcohol use, and subgroup differences in exposure to community violence. Five subgroups were identified: abstainers (56.5%), initiators of wine and beer (12.5%); moderately frequent wine and beer users (10.3%); moderately frequent wine, beer, and liquor users who got drunk (12.0%); and highly frequent wine, beer, and liquor users who got drunk (8.6%). Subgroups differed across sex, grade, and racial-ethnic background. Subgroups characterized by severe alcohol use reported more frequent exposure to community violence and physical victimization, while controlling for nonviolent stressors. Consistent with stress-coping theory, the results indicate that experiencing physical victimization and witnessing community violence robustly relate to adolescents' high-risk alcohol use.

The association between child maltreatment and problematic alcohol use in adulthood in a large multi-ethnic cohort: the HELIUS study

AIMS

There is evidence that child maltreatment is associated with problematic alcohol use later in life. However, previous epidemiological studies that have examined the link between child maltreatment and adult problematic alcohol use have not considered ethnic differences. Therefore, the purpose of the current study was to investigate the relationship between child maltreatment and adult problematic alcohol use among six ethnic groups in the Netherlands, in a large, urban sample.

METHODS

This study used baseline data from the Healthy Life in an Urban Setting (HELIUS) study: a large-scale, multi-ethnic prospective cohort study conducted in Amsterdam, the Netherlands. Child maltreatment, current problematic alcohol use and several potential confounders (e.g. parental alcohol use) were assessed in participants (N = 23 356) of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Turkish and Moroccan origin. With logistic regression analyses, we examined effect modification by ethnicity on the association between child maltreatment and problematic alcohol use. Furthermore, we explored effect modification by ethnicity for specific types of child maltreatment, namely: physical, sexual and psychological abuse and emotional neglect.

RESULTS

Effect modification by ethnicity was present. Stronger associations between child maltreatment and problematic alcohol use were found in all ethnic minority groups compared to the Dutch reference group. Particularly strong associations between all four types of child maltreatment and alcohol use problems were found for the Moroccan origin group.

CONCLUSIONS

This study adds to a growing body of evidence that child maltreatment is associated with problematic alcohol use in adulthood. In addition, our findings indicate that ethnicity impacts this relationship. Although problematic alcohol use was more prevalent in the Dutch origin group, associations with child maltreatment were stronger in ethnic minority groups. Future studies on child maltreatment and alcohol use problems should also examine ethnic disparities and should further unravel how these disparities can be explained.

Disparities by Gender and Race/Ethnicity in Child Maltreatment and Memory Performance

Adverse childhood experiences, which include child maltreatment, are a major public health issue nationally. Child maltreatment has been linked to poorer cognitive functioning, which can start in childhood and persist into adulthood. However, studies examining the potential disparities by gender and race/ethnicity are lacking. The aim of this study was to assess the gender and racial/ethnic disparities in the association between child maltreatment and memory performance. Data were obtained from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (N = 11,624). Weighted multiple linear regression models were used to assess the associations between sexual abuse, physical abuse, neglect, and child maltreatment score and memory. Models were stratified by gender, race, and ethnicity. Men who were exposed to sexual abuse, neglect and two or three child maltreatment types scored one to three points lower (β = -1.44; 95% CI: -2.83, -0.06; β = -2.41; 95% CI: -3.75, -1.08; β = -3.35; 95% CI: -5.33, -1.37; β = -2.31; 95% CI: -3.75, -0.86) in memory performance compared to men who did not report sexual abuse, neglect, or child maltreatment, respectively. Black respondents who were exposed to sexual abuse scored two points lower (β = -1.62; 95% CI: -2.80, -0.44) in memory performance compared to Black respondents who did not report sexual abuse. Among Other race and Hispanic respondents, those who reported neglect scored four points lower (β = -4.06; 95% CI: -6.47, -1.66; β = -4.15; 95% CI: -5.99, -2.30) in memory performance, respectively, compared to their counterparts who did not report neglect. Gender- and racial/ethnic-responsive memory performance interventions addressing child maltreatment may be beneficial for affected populations.

Early life stress and substance use disorders: The critical role of adolescent substance use

Early life stress (ELS) is a well-established risk factor for many psychiatric and medical disorders, including substance use disorders (SUDs). The relationship between ELS and SUDs is complex and there are likely multiple pathways from ELS to adverse substance use outcomes. The association between ELS and substance use emerges in adolescence. Adolescence is a critical period in development during which substance exposure markedly increases risk for SUDs. Therefore, this review focuses on the literature supporting the hypothesis that ELS increases risk for the development of SUDs through its influence on adolescent substance use. We discuss studies substantiating the role of ELS in adolescent substance use and explore how internalizing and externalizing psychopathology may be antecedents of substance use in adolescence. We examine clinical work suggesting ELS sculpts the Hypothalamic-Pituitary-Adrenal (HPA) Axis and developing brain-particularly subcortical brain regions that underlie stress response, mesocorticolimbic brain systems associated with reward sensitivity, and prefrontal regions that underlie executive control-in a way that increases risk for adolescent substance use and SUDs. We further explore how substance use during adolescence alters structure and function of these same systems, and how brain changes following ELS and adolescent substance use may independently, additively, or interactively contribute to risk for addiction. We conclude by discussing how the current literature can inform interventions aimed at reducing risk for SUDs in individuals with a history of ELS.

Trajectories of early alcohol use milestones: Interrelations among initiation and progression

BACKGROUND

Alcohol use shows age-graded patterning, with normative use progressing through characteristic milestones of escalating use or severity. Despite some knowledge about the timing of milestone attainment and sequencing across milestones, there is a gap in our understanding of the earliest stages of use. This study characterizes the timing, sequencing, and speed of progression through milestones beginning with the first sip of alcohol.

METHODS

Sixth through eighth graders (N = 1023; 52% female; 76% White; M = 12.23 years old) completed web surveys through the end of high school. Participants reported on alcohol experiences including the first sip, full drink, consumption of 3+ drinks/occasion (heavy drinking), being drunk, and experiencing acute consequences, from which milestone age and speed of progression (duration) were calculated. Milestone prevalence, sequencing, and timing were characterized, and associations between age of attainment and speed of progression were examined. We also examined whether milestone timing and progression varied by sex and racial/ethnic group.

RESULTS

Overall, milestones followed the expected ordering with the exception of heavy drinking (3+ drinks/occasion) and being drunk, which appear to index similar experiences. An earlier age of attainment was associated with an increased likelihood of attaining each of the milestones. In contrast, once a milestone was achieved, there was reduced risk of initiation of subsequent adjacent milestones for individuals with an earlier first sip and full drink, and earlier initiation was associated with a longer duration to subsequent milestones. Girls were more likely to attain all milestones than boys, but there was no sex difference in the age of attainment. In contrast, Hispanic youth reported earlier ages of initiation than White non-Hispanic youth, but the likelihood of attainment did not vary by race/ethnicity. Rapid progression was observed in females but did not vary by race/ethnicity.

DISCUSSION

Risks associated with early drinking are complex, with little support for normative ordering of milestones beyond the first sip. Although early drinking is associated with an increased risk of subsequent drinking, it does not appear to place the drinker on an accelerated course to heavier use. A nuanced understanding of risks associated with milestone timing may inform intervention efforts.

Childhood maltreatment, motives to drink and alcohol-related problems in young adulthood

BACKGROUND

Young adults with a history of child maltreatment (CM) are often vulnerable to alcohol-related problems. Drinking motives have been widely studied to explain alcohol-related problems in young adulthood.

OBJECTIVES

The aims of the current study were to examine the link between CM and alcohol-related problems and to test whether CM is indirectly related to alcohol-related problems via different types of drinking motives.

PARTICIPANTS AND SETTING

Two hundred eight participants were recruited in a mid-Atlantic urban area (M age = 19.7, 78.4 % female) via advertisements placed throughout the community.

METHODS

Participants completed self-report measures of CM (Childhood Trauma Questionnaire), types of drinking motives (the Drinking Motives Questionnaire Revised Short Form), and alcohol-related problems (Rutgers Alcohol Problem Index). Structural equation modeling (SEM) was used to test whether CM was associated with alcohol use, both directly and indirectly, through drinking motives.

RESULTS

We found that both coping (β = 0.53,p < 0.001) and enhancement drinking motives (β = 0.15, p = 0.031) were associated with alcohol-related problems. Additionally, CM was related to alcohol-related problems indirectly via coping motive (β = 0.11, p = 0.028).

CONCLUSION

Young adults with a history of CM may use alcohol to cope with trauma-related negative emotionality. Targeting emotional distress in CM-exposed individuals may be helpful in preventing and treating alcohol-related problems in this vulnerable population.

Childhood Trauma, Emotion Regulation, and Pain in Individuals With Alcohol Use Disorder

Introduction: Several studies have confirmed that the experience of childhood trauma, poor emotion regulation, as well as the experience of physical pain may contribute to the development and poor treatment outcomes of alcohol use disorder (AUD). However, little is known about how the joint impact of these experiences may contribute to AUD. Objectives: To analyze associations between childhood trauma, emotion regulation, and pain in individuals with AUD. Methods: The study sample included 165 individuals diagnosed with AUD. The Childhood Trauma Questionnaire (CTQ) was used to investigate different types of trauma during childhood (physical, emotional, and sexual abuse and neglect), the Brief Symptom Inventory was used to assess anxiety symptoms, the Difficulties in Emotion Regulation Scale (DERS) was used to assess emotional dysregulation, and the Pain Resilience Scale and Pain Sensitivity Questionnaire were used to measure self-reported pain tolerance and sensitivity. Results: Childhood emotional abuse (CTQ subscale score) was positively associated with anxiety, anxiety was positively associated with emotional dysregulation, and emotional dysregulation was negatively associated with pain tolerance. Accordingly, there was support for a significant indirect negative association between childhood emotional abuse and pain tolerance. The serial mediation statistical procedure demonstrated that anxiety and emotional dysregulation mediated the effect of childhood emotional abuse on pain resilience among individuals with AUD. Conclusions: Targeting emotional dysregulation and physical pain that can result from childhood trauma may have particular therapeutic utility among individuals treated for AUD.
