BACKGROUND: American Indian (AI) adolescents are disproportionately burdened by alcohol abuse and heavy binge use, often leading to problematic drinking in adulthood. However, many AI communities also have large proportions of adults who abstain from alcohol. OBJECTIVE: To understand these concurrent and divergent patterns, we explored the relationship between risk and protective factors for heavy binge alcohol use among a reservation-based sample of AI adolescents...

Studies looking at the relationship of the hypothalamic-pituitary-adrenal (HPA) axis to suicidal behavior and its risk factors, such as depression, childhood abuse, and impulsive aggression, report inconsistent results. These studies also do not always differentiate between subjects who go on to attempt suicide, suicidal subjects who never attempted suicide, and non-suicidal subjects with psychiatric disorders. In this study, we examined cortisol responses to an experimental stressor, the Trier Social Stress Test (TSST), in 208 offspring of parents with mood disorder...

Research suggests that school-age children with disruptive behavior (DB) problems frequently demonstrate impaired social skills and experience rejection from peers, which plays a crucial role in the pathway to more serious antisocial behavior. A critical question is which DB problems in early childhood are prognostic of impaired social functioning in school-age children. This study examines the hypothesis that aggression in early childhood will be the more consistent predictor of compromised social functioning than inattentive, hyperactive-impulsive, or oppositional behavior...

BACKGROUND: Although there are accumulating data regarding the epidemiology of suicide in China, there are meager data on suicidal ideation and attempts among college students. Interestingly, elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior. Therefore, the objective of this research was to identify the associations between suicide and the personality factors of impulsivity and aggression. METHODS: This study's sampling method employed stratified random cluster sampling...

Attention deficit hyperactivity disorder (ADHD) is the most frequently diagnosed behavioral disorder in children with a high frequency of co-morbid conditions like conduct disorder (CD) and oppositional defiant disorder (ODD). These traits are controlled by neurotransmitters like dopamine, serotonin and norepinephrine. Monoamine oxidase A (MAOA), a mitochondrial enzyme involved in the degradation of amines, has been reported to be associated with aggression, impulsivity, depression, and mood changes. We hypothesized that MAOA can have a potential role in ADHD associated CD/ODD and analyzed 24 markers in a group of Indo-Caucasoid subjects...

BACKGROUND: Extremely high rates of suicide localized within subgroups of populations where suicide is rare have been reported. We investigated this intriguing observation in a population of South-East Asia, where local culture should theoretically be preventative of suicide. METHOD: A team including an anthropologist and a psychiatrist surveyed all cases of suicide that had occurred over 10 years in four isolated regions. A psychological autopsy was carried out comparing each suicide case with two matched control cases...

OBJECTIVE: The aim of this study was to determine whether pre-licence driving experiences, that is driving before beginning the licensing process, increased or decreased crash risk as a car driver, during the learner or the restricted licence stages of the graduated driver licensing system (GDLS). METHOD: Study participants were 15-24 year old members of the New Zealand Drivers Study (NZDS) - a prospective cohort study of newly licensed car drivers. The interview stages of the NZDS are linked to, the three licensing stages of the GDLS: learner, restricted and full...

Clinical theory predicts that individuals high in psychopathic traits possess average or above average intelligence; however findings in adult and child samples have been mixed. The present study aimed to investigate (1) the relationship between verbal and nonverbal intelligence and the three dimensions of psychopathy (callous-unemotional (CU) traits, narcissism, impulsivity); and (2) whether these dimensions moderate the association between verbal and nonverbal intelligence and the severity of antisocial behavior...

The purpose of this study was to determine whether five subcomponents of children's externalizing behavior showed distinctive patterns of long-term growth and predictive correlates. We examined growth in teachers' ratings of overt aggression, covert aggression, oppositional defiance, impulsivity/inattention, and emotion dysregulation across three developmental periods spanning kindergarten through Grade 8 (ages 5-13 years). We also determined whether three salient background characteristics, family socioeconomic status, child ethnicity, and child gender, differentially predicted growth in discrete categories of child externalizing symptoms across development...

To investigate response to Divalproex sodium (DVPX) with respect to Reactive/Affective/Defensive/Impulsive (RADI) and Proactive/Instrumental/Premeditated (PIP) aggression among adolescent males with conduct disorder (CD), using results from a randomized, double-blind, placebo-controlled trial. It was hypothesized that DVPX response among participants with RADI aggression would be greater than among those with PIP aggression. Fifty-eight ethnically diverse males with severe CD were assigned to High Distress (HDCD) or Low Distress (LDCD) Conduct Disorder, corresponding with RADI and PIP aggression, respectively...

BACKGROUND: There is a decreased serotonergic function in impulsive aggression and borderline personality disorder (BPD), and genetic association studies suggest a role of serotonergic genes in impulsive aggression and BPD. Only one study has analyzed the association between the tryptophan-hydroxylase 2 (TPH2) gene and BPD. A TPH2 "risk" haplotype has been described that is associated with anxiety, depression and suicidal behavior. METHODS: We assessed the relationship between the previously identified "risk" haplotype at the TPH2 locus and BPD diagnosis, impulsive aggression, affective lability, and suicidal/parasuicidal behaviors, in a well-characterized clinical sample of 103 healthy controls (HCs) and 251 patients with personality disorders (109 with BPD)...

Peer nominations and demographic information were collected from a diverse sample of 1493 elementary school participants to examine behavior (overt and relational aggression, impulsivity, and prosociality), context (peer status), and demographic characteristics (race and gender) as predictors of teacher and administrator decisions about discipline. Exploratory results using classification tree analyses indicated students nominated as average or highly overtly aggressive were more likely to be disciplined than others...

Borderline personality disorder (BPD) is marked by aggression and impulsive, often self-destructive behavior. Despite the severe risks associated with BPD, relatively little is known about the disorder's etiology. Identification of genetic correlates (endophenotypes) of BPD would improve the prospects of targeted interventions for more homogeneous subsets of borderline patients characterized by specific genetic vulnerabilities. The current study evaluated behavioral measures of aggression and impulsivity as potential endophenotypes for BPD...

UNLABELLED: Suicidal behavior runs in families and is partially genetically determined. Since greater serotonin 5-HT(2A) receptor binding has been reported in postmortem brain and platelets of suicide victims, the 5-HT(2A) receptor gene polymorphism T102C became one of the candidate sites in the study of suicide and impulsive-aggressive traits. However, studies that examined the association of this polymorphism with suicidality have contradictory results. This study used a family-based method and one homogenous ethnic group to overcome ethnic stratification in order to test this association...

OBJECTIVE: Compelling evidence suggests that serotonin system dysfunction is associated with certain behavioral disorders, including suicidal behavior and impulsive aggression. A functional polymorphism in the promoter region of the monoamine oxidase A gene (uVNTR) was recently identified and the presence of the 2-3 alleles was found to be associated with a higher level of transcription, central nervous system serotonergic responsivity and impulsive aggression. A dinucleotide repeat in intron 2 of the gene (monoamine oxidase A-CAn) has been described previously, and is in linkage disequilibrium with the variable number of tandom repeats (VNTR)...

Serotonergic dysfunction is believed to be involved in the susceptibility to suicide due to functional alternations in the serotonin-related genes. Serotonin 1B (5HT-1B) receptor mediates aggressive behavior in mice models and was proposed to be involved in the control of aggression and impulsivity in humans. In this study we have investigated the association of G861C polymorphism of the 5HT-1B receptor gene with suicide commitment. Study was based on two independent samples, one of German (245 suicide victims vs...

BACKGROUND: A limited amount of information pertaining to ethnic-specific risk factors associated with intimate partner violence across time currently exists. The current study examines ethnic-specific longitudinal predictors of male-to-female and female-to-male partner violence (MFPV and FMPV) in white, black, and Hispanic couples in the U.S. general population. METHODS: In 1995, a total of 1635 married or cohabitating couples 18 years of age or older living in households in the 48 contiguous states participated in a national survey that used a multistage probability sampling procedure with 100 primary sampling units and included oversamples of blacks and Hispanics...

Suicidal behavior runs in families and seemed to be genetically determined in part and independent of the presence of psychiatric disorders. This review presents the current knowledge of candidate gene association studies in the field of suicidology. Concordance for monozygotic twins is about 13% Vs. 0.7% in dizygotics. It seems that there is a relationship to intermediate phenotypes such as impulsivity and aggression. The problem of studying complex traits and of ethnic stratification in heterogeneous population are major concerns in studying genetics of suicide...
