Purpose: A large body of empirical research finds a significant racial gap in the use of exclusionary school discipline with black students punished at rates disproportionate to whites. Furthermore, no variable or set of variables have yet to account for this discrepancy, inviting speculation that this association is caused by racial bias or racial antipathy. We investigate this link and the possibility that differential behavior may play a role. Methods: Using data from the Early Childhood Longitudinal Study, Kindergarten Class (ECLS-K), the largest sample of school-aged children in the United States, we first replicate the results of prior studies. We then estimate a second model controlling for prior problem behavior. Results: Replicating prior studies, we first show a clear racial gap between black and white students in suspensions. However, in subsequent analyses the racial gap in suspensions was completely accounted for by a measure of the prior problem behavior of the student – a finding never before reported in the literature. Conclusions: These findings highlight the importance of early problem behaviors and suggest that the use of suspensions by teachers and administrators may not have been as racially biased as some scholars have argued.

Although educational attainment has been found to be moderately heritable, research has yet to explore candidate genes for it. Drawing on data from the National Longitudinal Study of Adolescent Health, in the current study, we examined the association between polymorphisms in three dopaminergic genes (DAT1, DRD2, and DRD4), a dopamine index, and educational attainment. Statistically significant effects were found for DAT1, DRD2, DRD4, and the dopamine index for highest level of education. This study is the first to our knowledge that links measured genes to educational attainment. [ABSTRACT FROM AUTHOR]

A range of Gene × Environment interactions is associated with antisocial phenotypes, and the evidence is clear that the etiology of antisocial behavior is strongly heritable and that environmental liabilities are important. However, the precise ways that genetic and environmental pathogens interact to predict antisocial behavior are underspecified. The present study shows that the interaction between a polymorphism in a dopamine receptor gene (DRD2) and a criminal father predicts five antisocial phenotypes among African American females (n = 232) in the National Longitudinal Study of Adolescent Health. Genetic risk (as measured by the A1 allele) and a criminal father interacted to predict serious and violent delinquency at Wave 1, serious and violent delinquency at Wave 2, and number of police contacts. The current investigation represents the first study to show Gene × Environment interactions in the prediction of antisocial phenotypes using criminal justice system status as an environmental pathogen.

Recently, the concept of "collective efficacy" has been advanced to understand how communities exert control and provide support to reduce crime. In a similar way, we use the concept of "parental efficacy" to highlight the crime reducing effects associated with parents who support and control their youth. Using data from the National Longitudinal Survey of Youth (NLSY), we examine the inter-relationship between parental controls and supports and their joint influence on youthful misbehavior. The results show that (1) support and control are intertwined, and (2) that parental efficacy exerts substantive effects on adolescent delinquency for the sample as a whole and across varying age groups.

We assessed the oral health status of 216 refugee torture survivors seeking care at an urban torture treatment center in the United States. Results showed that patients' dental health ranged from poor to fair; 76% had untreated cavities, and approximately 90% required immediate or near-immediate dental care. Torture treatment centers, in addition to offering safe environments for educating and examining patients, are ideal settings to provide basic oral health services without the risk of retraumatization.

Research has shown that offenders, on average, are more likely to be violently victimized than nonoffenders. However, a substantial percentage of offenders are not violently victimized. The current study uses data from the National Longitudinal Study of Adolescent Health (Add Health) to investigate whether variants of a polymorphism in the dopamine D2 receptor gene (DRD2) distinguish between offenders who are violently victimized and offenders who are not violently victimized. The results show that offenders who are violently victimized are more likely to carry the DRD2 (A1) risk allele than offenders who have not been violently victimized.

Behavioral genetic research has consistently revealed that genetic factors explain at least one half of the variance in measures of cognitive skills. However, the specific DNA markers involved in the etiology of cognitive abilities have remained elusive. The current study examined the association between the TaqI polymorphism in the dopamine D2 receptor gene (DRD2) and verbal skills. Analysis of data drawn from the National Longitudinal Study of Adolescent Health (Add Health) revealed that the A1 allele was associated with group membership in high-, average-, and low-verbal skills groups for Caucasians. The results suggest that DRD2 may be related to domain specific cognitive abilities, such as verbal skills.

Fire-setting is a serious and costly form of antisocial behavior. Our objective in this study was to examine the prevalence and correlates of intentional fire-setting behavior in the United States. Data were derived from a nationally representative sample of US residents 18 years and older. Structured psychiatric interviews (N = 43,093) were completed by trained lay interviewers between 2001 and 2002. Fire-setting as well as mood, anxiety, substance use, and personality disorders of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition were assessed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) version. The prevalence of lifetime fire-setting in the US population was 1.0%. Respondents who were men, white, 18 to 35 years old, born in the United States, and living in the western region of the United States had significantly higher rates of fire-setting than their counterparts. Fire-setting was significantly associated with a wide range of antisocial behaviors. Multivariate logistic regression analyses identified strong associations between lifetime alcohol and marijuana use disorders, conduct disorder, antisocial and obsessive-compulsive personality disorders, and family history of antisocial behavior. Intentional illicit fire-setting behavior is associated with a broad array of antisocial behaviors and psychiatric comorbidities. Given the substantial personal and social costs related to arson, prevention and treatment interventions targeting fire-setters potentially could save lives and property., (2010 Elsevier Inc.

This study uses data from the National Longitudinal Study of Adolescent Health to examine whether a polymorphism in the serotonin transporter gene (SHTTLPR) moderates the effects of marijuana use on property offending. The results reveal that 5HTTLPR interacts with marijuana use to predict significantly higher levels of property offending for African American females. The interaction coefficient is not statistically significant for Caucasian males, African American males, or Caucasian females. These findings suggest that marijuana use is associated only with higher levels of property offending among African American females who carry one or more copies of the 5HTTLPR short allele.

We examined the effects of anabolic-androgenic steroid use on serious violent behavior. Multivariate models based on data from the National Longitudinal Study of Adolescent Health (N = 6823) were used to examine the association between lifetime and past-year self-reported anabolic-androgenic steroid use and involvement in violent acts. Compared with individuals who did not use steroids, young adult males who used anabolic-androgenic steroids reported greater involvement in violent behaviors after we controlled for the effects of key demographic variables, previous violent behavior, and polydrug use.

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N= 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delinquent peer affiliation for male adolescents from high-risk environments (beta range = .13-.14) despite controlling for delinquent involvement, self-control, and drug and alcohol use. The authors discuss the importance of using a biosocial framework to examine issues related to adolescent development.

Empirical research has revealed a positive relationship between number of sex partners and involvement in antisocial behaviors. Most attempts to explain this association have taken an evolutionary perspective and argued that the same traits (e.g., impulsiveness, shortsightedness, and aggressiveness) that are related to a large number of sex partners are also related to criminal involvement. However, there is also reason to believe that the covariation between sex partners and crime behaviors can be partially explained by a common genetic pathway, where genes that are related to sex partners are also related to antisocial conduct. We test this possibility by using data from the National Longitudinal Study of Adolescent Health (Add Health). Specifically, we examine whether variants of the dopamine transporter gene (DAT1) are associated with number of sexual partners and with adult criminal behavior. The results of our analyses reveal two broad findings. First, and in line with prior research, we find that there is a strong positive association between sex partners and antisocial behavior. Second, DAT1 explains variation in both number of sexual partners and in criminal conduct for males. We speak to the implications of our findings.

A large body of research has revealed that aggressive personality traits and violent criminal behaviors are influenced by genetic factors. Surprisingly, however, no research has been devoted to investigating the potential genetic origins to adolescent victimization. In the current study, the authors address this gap in the literature by using data from the National Longitudinal Study of Adolescent Health (Add Health) to examine whether different variants of the dopamine D2 receptor gene (DRD2) are related to victimization, net of the effects of environmental measures. The results of the multivariate models revealed a significant gene X environment interaction in the creation of victimization for White males. Specifically, DRD2 interacted with delinquent peers to predict victimization. The authors discuss the implications of these findings.
