Child maltreatment and substances use throughout adolescence and adulthood: Data from a Brazilian Birth Cohort

Childhood maltreatment as a predictor of substance use/misuse among youth: A systematic review and meta-analysis

This systematic review and meta-analysis aimed to comprehensively describe whether experiencing a variety of childhood maltreatment types predicts a variety of substance use/misuse types among youth, beyond the narrow scope covered in previous systematic reviews on similar topics. A literature search was conducted in June, 2022 using PubMed, PsycInfo, and Embase. 58 studies (total participant n=170,749) were included. These studies were primarily organized by substance type outcomes including alcohol (n=43), cannabis (n=25), unspecified substances (n=25), and other specific substances (n=10). Results were further stratified by maltreatment type. For specific maltreatment and substance type combinations, the majority of studies indicated that childhood maltreatment was a significant predictor of substance use/misuse in youth. Of the 10 meta-analyses we conducted, significant associations were found for the majority (9/10) of maltreatment and substance type combinations. For instance, unspecified childhood maltreatment increased the probability of youth alcohol use by about four times, which was the highest relative risk found. In conclusion, this study shows that childhood maltreatment is a predictor of youth substance use/misuse.

Psychological maltreatment and substance use among college students: Psychological distress, belongingness, and social support

Substance use in college students is an important public health problem associated with substantial consequences. It is a critical step to examine risk and protective factors associated with substance use to develop prevention and intervention strategies for promoting college students' healthy development and well-being. The present cross-sectional study aimed to examine the mediating role of psychological distress in the relationship between childhood psychological maltreatment and substance use and the moderating effect of social support and belongingness in this association among college students. The sample of this cross-sectional study included 382 emerging adults. Participants included 56.8% female and 43.2% male, and they ranged in age between 20 and 29 years (M = 22.05, SD = 2.17). Findings from the study first confirmed that psychological maltreatment was a significant predictor of social support, belongingness, psychological distress, and substance use. Subsequent results revealed that psychological distress mediated the association between psychological maltreatment and college students' substance use. Also, belongingness and social support had a buffering effect on this association. The findings suggest that psychological maltreatment is a significant risk factor in developing substance use behavior and that belongingness and social support services can serve as protective resources. Based on these results, prevention and intervention services focusing on improving the feeling of belonging and social support could be conducive to the decreased substance use of psychologically maltreated emerging adults.

Psychological flexibility, self-compassion, subjective well-being, and substance misuse in college students: a serial mediation model

Substance misuse is a pressing public health concern, especially among emerging adults, with implications for psychological health and overall well-being. This cross-sectional study investigates the mediating roles of self-compassion and subjective well-being in the relationship between psychological flexibility and substance misuse among Turkish college students. The study included 445 emerging adults enrolled at a state university in Türkiye. University participants were recruited via convenience sampling using snowball methods. Data were collected using self-report scales. The sample was 69% female (n = 307) and 31% male (n = 138) and ranged in age from 18 to 26 years (M = 20.85, SD = 1.35). In the study, Pearson product-moment correlation analysis was conducted to examine the relationships between the variables and then the serial mediation model was tested. The findings have revealed that psychological flexibility significantly predicts substance misuse, subjective well-being, and self-compassion. Additionally, the study identifies self-compassion as a mediator in the relationship between psychological flexibility and subjective well-being. While self-compassion contributes significantly to well-being, it does not explain the impact of psychological flexibility on substance misuse. Furthermore, subjective well-being also appears to be a mediator in the relationship between psychological flexibility and substance misuse, emphasizing its potential significance in reducing the likelihood of resorting substance misuse. Overall, the study contributes to understanding the pivotal role of self-compassion and psychological flexibility in fostering well-being and preventing substance misuse in the college setting.

Associations Between Childhood Trauma and Tobacco Use Outcomes in Adults after Overnight Abstinence

INTRODUCTION

Childhood trauma is known to be associated with nicotine dependence, yet limited smoking outcomes have been examined and few studies have assessed associations between specific trauma subscales and smoking. Additionally, sex differences in trauma-smoking relations are understudied. This study examined associations between childhood trauma and several smoking-related outcomes in adults who smoke after overnight abstinence.

AIMS AND METHODS

People who smoke (N = 205) completed self-report and biochemical assessments evaluating childhood trauma, affect, nicotine dependence, smoking urges, withdrawal, and plasma cortisol and cotinine levels. Smoking outcomes were compared between those with and without a history of moderate to severe childhood trauma among the total sample and by sex.

RESULTS

Relative to those with no to minimal abuse, those with moderate to severe abuse had higher negative affect, withdrawal severity, and plasma cotinine levels. Exploratory analyses revealed that women were more likely than men to have urges to smoke for negative reinforcement and have higher withdrawal severity, but no interactions between abuse group and sex were observed. Examining specific trauma subscales, the moderate to severe emotional abuse group had more severe nicotine dependence, negative affect, and withdrawal compared to the no to minimal group. The moderate to severe sexual abuse group had more severe nicotine dependence and withdrawal compared to the no to minimal group.

CONCLUSIONS

Exposure to childhood trauma is associated with more severe nicotine dependence, negative affect, withdrawal, and higher plasma cotinine levels. Findings also indicate that different types of trauma may differentially affect smoking behaviors.

IMPLICATIONS

This study of adults who smoke finds that childhood trauma history may be a marker for smoking susceptibility and suggests that individuals with experiences of emotional and sexual abuse may require targeted forms of smoking cessation interventions. Moreover, findings suggest that smoking risks may differ for men and women. Findings inform public health interventions intended to reduce cigarette use in individuals with exposure to childhood trauma.

Health effects associated with exposure to intimate partner violence against women and childhood sexual abuse: a burden of proof study

The health impacts of intimate partner violence against women and childhood sexual abuse are not fully understood. Here we conducted a systematic review by comprehensively searching seven electronic databases for literature on intimate partner violence-associated and childhood sexual abuse-associated health effects. Following the burden of proof methodology, we evaluated the evidence strength linking intimate partner violence and/or childhood sexual abuse to health outcomes supported by at least three studies. Results indicated a moderate association of intimate partner violence with major depressive disorder and with maternal abortion and miscarriage (63% and 35% increased risk, respectively). HIV/AIDS, anxiety disorders and self-harm exhibited weak associations with intimate partner violence. Fifteen outcomes were evaluated for their relationship to childhood sexual abuse, which was shown to be moderately associated with alcohol use disorders and with self-harm (45% and 35% increased risk, respectively). Associations between childhood sexual abuse and 11 additional health outcomes, such as asthma and type 2 diabetes mellitus, were found to be weak. Although our understanding remains limited by data scarcity, these health impacts are larger in magnitude and more extensive than previously reported. Renewed efforts on violence prevention and evidence-based approaches that promote healing and ensure access to care are necessary.

Notifications of physical, sexual and emotional violence and neglect against children in Brazil, 2011-2019: an ecological time-series study

OBJECTIVE

To describe the temporal trend of notifications of physical, sexual and emotional violence and neglect against children in Brazil between 2011 and 2019.

METHODS

This was an ecological time-series study based on notifications of violence against children aged 0-9 years held on the Brazilian Notifiable Health Conditions Information System. Age-adjusted notification rates were calculated for Brazil as a whole, by national macro-region and by sex. Trends were assessed using Joinpoint Regression.

RESULTS

We analyzed 88,820 notifications of physical violence, 87,141 notifications of sexual violence, 52,359 notifications of emotional violence and 166,664 notifications of neglect. A rising trend was identified for notifications of physical, sexual and emotional violence and neglect for Brazil as a whole and for both sexes. Neglect accounted for the highest rate (95.24 notifications per 100,000 children in 2019). The Northeast and Southeast macro-regions had rising trends for all forms of violence.

CONCLUSION

Notifications of physical, sexual and emotional violence and neglect showed rising trends in Brazil in the period studied.

IMPLICATIONS FOR SERVICES

Increasing trends in notifications of violence against children highlight the continued need for capacity building in health services, crucial for early detection, effective prevention and coordinated intervention, taking regional variations into account.

PERSPECTIVES

Notification of violence against children by health services requires greater commitment by health workers. Future studies could combine multiple national databases and surveys to increase the accuracy of rates and trends.

Problematic alcohol use in young adults exposed to childhood trauma: The Trøndelag Health (HUNT) Study

Problematic alcohol use (PAU) severely impacts the health, functioning, and long-term prospects of young people. Prior research indicates that childhood trauma exposure may be an important risk factor for PAU, but few longitudinal studies have looked at how specific trauma types influence this risk. The aim of this study was to investigate the association between childhood trauma exposure and PAU in a large, population-based cohort of young people. The study sample included 1,913 adolescents who participated in the Trøndelag Health Study (HUNT) between 2006 and 2008 (age range: 12-20) and completed follow-up 10 years later as young adults (age range: 22-32). The results revealed an increased risk of PAU in young adults exposed to childhood trauma, especially direct physical violence, OR = 2.38, [95% CI 1.56, 3.64]. Young adults who had witnessed violence, OR = 1.55, [95% CI 1.11, 2.17], or experienced an accident, disaster, or other traumatic event, OR = 1.60, [95% CI 1.19, 2.15], also had higher odds of PAU compared to those without such experiences. These associations remained consistent after adjusting for symptoms of headaches and pain as well as posttraumatic and general psychological distress as reported by the participants in adolescence. Future prevention efforts targeting PAU among adolescents and young adults should address violence and other trauma exposure as potential drivers of problematic drinking.

Dysfunctional parenting and emotional problems and substance misuse: Enhancing psychological flexibility in college students

This cross-sectional study aimed to investigate the mediating role of psychological flexibility in the relationship between dysfunctional parenting (i.e., dysfunctional parent modes) and emotional problems and substance misuse among Turkish college students. Participants were 466 undergraduate students (69% female) aged between 18 and 45 years (M = 21.46, SD = 3.31) from a public university in Turkey. The majority of participants in the study reported never or infrequent use of tobacco, alcohol, and prescription drugs, with daily or almost daily use reported by less than a quarter of the sample for each substance. Results showed that higher levels of dysfunctional parent modes were associated with increased emotional problems and substance misuse. Moreover, psychological flexibility mediated the relationship between dysfunctional parent modes and emotional problems, as well as both mediated and moderated the relationship between dysfunctional parent modes and substance misuse. Results from the study also showed that people in the at-risk group for substance misuse reported higher levels of dysfunctional parent modes and emotional problems, as well as lower levels of psychological flexibility than the typical group. These results suggest that psychological flexibility may play a significant role in the link between dysfunctional parent modes and emotional problems and substance misuse among Turkish college students. Future research should investigate whether interventions targeting psychological flexibility could be effective in reducing emotional problems and substance misuse among students with dysfunctional parent modes.

Do Coping Motives and Perceived Impaired Control Mediate the Indirect Links from Childhood Trauma Facets to Alcohol-Related Problems?

INTRODUCTION

The Self-Medication Hypothesis suggests that individuals drink to alleviate undesirable affective states. Behavioral Economics Theory states that individuals deprived of resources (i.e., physically neglected) consume more reinforcing substances when they are available than others. Childhood trauma may indirectly increase impaired control over alcohol (IC; drinking beyond one's own intentions) and thereby increase alcohol use and problems through the employment of coping-motives.

METHOD

A structural equation model that included sex as a covariate examined mediated paths with 612 university students.

RESULTS

Men were less likely to be emotionally abused and were more likely to use greater amounts of alcohol than women did. Physical neglect was directly linked to both more IC and alcohol use. Emotional and sexual abuse were directly linked to more coping motives. Both emotional and sexual abuse were indirectly linked to more alcohol use and its related problems through increased coping motives and IC.

CONCLUSIONS

Consistent with Behavioral Economics Theory, there was a direct link between physical neglect and IC. We also found partial support for the Self-Medication Hypothesis regarding the emotional and sexual abuse trauma dimensions; they indirectly contributed to alcohol use and its related problems via the mediating mechanisms of more coping motives and IC. Our findings suggest coping motives could be a therapeutic target for intervention among those sexually or emotionally abused.
