Childhood maltreatment, psychiatric symptoms, and suicidal thoughts among adolescents receiving substance use treatment services

Do dimensions of childhood adversity differ in their direct associations with youth psychopathology? A meta-analysis

Growing evidence supports the unique pathways by which threat and deprivation, two core dimensions of adversity, confer risk for youth psychopathology. However, the extent to which these dimensions differ in their direct associations with youth psychopathology remains unclear. The primary aim of this preregistered meta-analysis was to synthesize the associations between threat, deprivation, internalizing, externalizing, and trauma-specific psychopathology. Because threat is proposed to be directly linked with socioemotional development, we hypothesized that the magnitude of associations between threat and psychopathology would be larger than those with deprivation. We conducted a search for peer-reviewed articles in English using PubMed and PsycINFO databases through August 2022. Studies that assessed both threat and deprivation and used previously validated measures of youth psychopathology were included. One hundred and twenty-seven articles were included in the synthesis (N = 163,767). Results of our three-level meta-analyses indicated that adversity dimension significantly moderated the associations between adversity and psychopathology, such that the magnitude of effects for threat (r's = .21-26) were consistently larger than those for deprivation (r's = .16-.19). These differences were more pronounced when accounting for the threat-deprivation correlation. Additional significant moderators included emotional abuse and youth self-report of adversity. Findings are consistent with the Dimensional Model of Adversity and Psychopathology, with clinical, research, and policy implications.

The neurobiological effects of childhood maltreatment on brain structure, function, and attachment

Childhood maltreatment is a risk factor for psychopathologies, and influences brain development at specific periods, particularly during early childhood and adolescence. This narrative review addresses phenotypic alterations in sensory systems associated with specific types of childhood maltreatment exposure, periods of vulnerability to the neurobiological effects of maltreatment, and the relationships between childhood maltreatment and brain structure, function, connectivity, and network architecture; psychopathology; and resilience. It also addresses neurobiological alterations associated with maternal communication and attachment disturbances, and uses laboratory-based measures during infancy and case-control studies to elucidate neurobiological alterations in reactive attachment disorders in children with maltreatment histories. Moreover, we review studies on the acute effects of oxytocin on reactive attachment disorder and maltreatment and methylation of oxytocin regulatory genes. Epigenetic changes may play a critical role in initiating or producing the atypical structural and functional brain alterations associated with childhood maltreatment. However, these changes could be reversed through psychological and pharmacological interventions, and by anticipating or preventing the emergence of brain alterations and subsequent psychopathological risks.

Direct and Indirect Effects of Child Maltreatment on Suicidal Ideation among Chinese Left-Behind Children: Does Gender Make a Difference?

Previous studies indicate that maltreatment is related to children’s suicidal ideation, but the indirect mechanisms of left-behind children have been rarely investigated in the Chinese context. On the basis of a left-behind children sample (N = 1355; 57.1% females), this study aims to investigate the direct and indirect effects of maltreatment on suicidal ideation among Chinese left-behind children. The results of structural equation modeling (SEM) demonstrate that child maltreatment not only directly affects the suicidal ideation of left-behind children, but can also indirectly affect their suicidal ideation through the partially mediating role of self-efficacy. Moreover, a significant gender difference was found in the direct effect of maltreatment on suicidal ideation, with females experiencing stronger influence than males. Findings suggest that the effect of maltreatment on the suicidal ideation of left-behind children is mediated by self-efficacy and moderated by gender. Findings also highlight intervention directions for risk behaviors among left-behind children.

Substance Abuse Amongst Adolescents: An Issue of Public Health Significance

Adolescence is a crucial time for biological, psychological, and social development. It is also a time when substance addiction and its adverse effects are more likely to occur. Adolescents are particularly susceptible to the negative long-term effects of substance use, including mental health illnesses, sub-par academic performance, substance use disorders, and higher chances of getting addicted to alcohol and marijuana. Over the past few decades, there have been substantial changes in the types of illegal narcotics people consume. The present article deals with the review of substance abuse as a public health problem, its determinants, and implications seen among adolescents. A systematic literature search using databases such as PubMed and Google Scholar was undertaken to search all relevant literature on teenage stimulant use. The findings have been organized into categories to cover essential aspects like epidemiology, neurobiology, prevention, and treatment. The review showed that substance addiction among adolescents between 12 to 19 years is widespread, though national initiatives exist to support young employment and their development. Research on psychological risk factors for teenage substance abuse is vast, wherein conduct disorders, including aggression, impulsivity, and attention deficit hyperactivity disorder, have been mentioned as risk factors for substance use. Parents' attitudes toward drugs, alcohol, academic and peer pressure, stress, and physical outlook are key determinants. Teenage drug usage has a significant negative impact on users, families, and society as a whole. It was found that a lot has been done to provide correct intervention to those in need with the constant development of programs and rehabilitative centers to safeguard the delicate minds of youths and prevent them from using intoxicants. Still, there is much need for stringent policy and program guidelines to curb this societal menace.

Interactive effects of childhood maltreatment and tonic respiratory sinus arrhythmia on young adults' depressive symptoms

The goal of the current study was to investigate the moderating effect of tonic respiratory sinus arrhythmia (RSA) in the relation between childhood maltreatment and depression symptoms among young adults. A total of 98 participants (70 women) aged 17-22 years completed questionnaires on childhood maltreatment and depressive symptoms. RSA data were obtained during a resting condition in the laboratory. Results indicated that childhood maltreatment interacted with tonic RSA to predict depressive symptoms, even after controlling for age and body mass index (BMI) of each participant. Specifically, higher levels of childhood maltreatment were associated with higher levels of depressive symptoms, but only among young adults who exhibited lower tonic RSA. The results indicated that the association between childhood maltreatment and depressive symptoms depends on young adults' physiological functioning/flexibility. Findings suggest that consideration of external environmental factors in combination with internal physiological factors is critical to understand young adults' mental health.
