Longitudinal Risks for Domestic Violence

Much research has examined the connections between victimization experiences in the family during childhood, adolescence, and adulthood. However, research that frames these different victimization experiences across the life course as part of a broader, longitudinal risk for experiencing domestic violence on the part of the individual, particularly within a theoretically driven model, is lacking. The current study uses data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative sample of American adolescents, to examine how child abuse connects to victimization by dating partners during adolescence and victimization by romantic and marital partners during adulthood, and whether dating victimization mediates the relationship between child abuse and intimate partner victimization in adulthood. Results suggest that this is indeed the case, with child abuse having a direct effect on adolescent dating victimization and a direct and indirect effect on adult intimate partner victimization. Implications of the findings for theory and policy are discussed.

The Link Between Child Abuse and Neglect and Delinquency: Examining the Mediating Role of Social Bonds

ABSTRACT This article draws on previous research and social bonding theory to examine the child maltreatment–delinquency relationship. Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), results show that child physical and sexual abuse and neglect are predictors of weakened social bonds and increased delinquency during later adolescence. For both females and males, strong social bonds significantly decrease delinquency. Among females, social bonds, especially the maternal bond and school attachment, mediate the effects of child sexual abuse and neglect on delinquency. The effects of abuse and neglect on delinquency among males remain robust and significant even when controlling for social bonds. Implications of the findings for theory and policy are discussed.

5-HTTLPR, suicidal behavior by others, depression, and criminal behavior during adolescence

Vicarious strains like suicidal behavior on the part of others have been shown to be predictive of both negative emotions and antisocial behavior during adolescence. Little research to date, however, has examined the role that biological factors play in moderating these relationships. Using a sample of adolescents drawn from the National Longitudinal Survey of Adolescent Health (N = 7,995), and drawing on two separate, but related, theories, I explore whether the serotonin transporter gene (5-HTTLPR) interacts with suicidal behavior by others to affect depression and self-reported crime. Results of ordinary least squares and negative binomial regressions reveal that suicide by others interacts with 5-HTTLPR to increase both depression and crime for males but not females, net of controls. Thus, 5-HTTLPR may be implicated in shaping negative emotions and antisocial behavior among males during adolescence by moderating the effects of suicide by others. Implications for theory are discussed.

Relative and Absolute Deprivation’s Relationship With Violent Crime in the United States: Testing an Interaction Effect Between Income Inequality and Disadvantage:

Relative deprivation and absolute deprivation both have effects on crime. Although these two concepts are often treated as separate, some scholarship has suggested that the two may be complementary. The current study assesses whether the effects of relative and absolute deprivation interact statistically in their effect on violent crime by testing an interaction effect between income inequality and disadvantage. Using data from U.S. counties, hierarchical linear modeling (HLM) regression models show that there is a significant interaction between relative and absolute deprivation predicting violent crime rates. The plot of this interaction shows that when absolute deprivation is high, there is less violence in high inequality counties than in counties with medium levels of inequality. The implication of this finding is discussed.

When Does Religion Matter With Regard to Crime? Examining the Relationship Between Genetics, Religiosity, and Criminal Behavior:

Religiosity has been shown to be a predictor of initial criminal offending, reoffending, and desistance. To date, however, research has generally failed to assess the role that biological factors play in moderating the religiosity–crime relationship. The present study utilizes a nationally representative sample of male adolescents (N = 4,053), to explore whether variants of the dopamine transporter gene (DAT1) and the monoamine oxidase A gene (MAOA) interact with religiosity to affect self-reported criminal offending. Results of negative binomial regressions demonstrate that religiosity interacts with these genes to influence offending among males, net of controls. Importantly, once potential confounding variables are accounted for, a statistically significant effect of religiosity on offending among males is only evident for those who carry plasticity alleles for both DAT1 and MAOA (vs. carrying one or zero plasticity alleles). Thus, among males, whether religiosity is important for criminal offending depends partly on the individual genotype. Implications for theory and policy are discussed.

MAOA, Drug Selling, and Violent Victimization: Evidence of a Gene × Environment Interaction

Involvement in drug markets is a significant risk factor for criminal victimization. Separately, the monoamine oxidase A (MAOA) gene has been identified as correlating with risky and antisocial behaviors and moderating the effects of environmental risk factors on antisocial behaviors. Using a sample drawn from the National Longitudinal Study of Adolescent to Adult Health (N = 8,860), we explore whether MAOA genotype moderates the effect of drug selling on violent victimization. Results show that drug selling increases violent victimization among males, but not females. Additionally, the effect of drug selling on violent victimization among males is greater among the carriers of the 2R/3R alleles of MAOA, providing evidence of Gene × Environment interaction. These results appear despite a number of controls that potentially make the drug selling–violent victimization relationship spurious. Implications of the findings are discussed.

Gun Carrying and Gun Victimization among American Adolescents: A Fresh Look at a Nationally Representative Sample

ABSTRACT A scant literature has identified gun carrying as a potential risk factor for victimization at the individual level. To date, however, research has generally focused on high-risk individuals rather than samples drawn from the general population. Additionally, prior studies have not often enough included controls robust enough to feel strongly that the relationship between gun carrying and victimization, gun victimization in particular, is not simply the spurious outcome of factors that influence both variables. The current study uses data from Add Health participants (N = 13,568) to look at the effect of gun carrying on gun victimization among adolescents. Results suggest that even when robust controls are considered, a measure of gun carrying significantly and positively correlates with gun victimization. The results support a model of the gun carrying-gun victimization relationship wherein gun carrying increases risks for gun victimization independent of factors that may influence both risky behaviors and victimization. Implications for theory and policy are discussed.

ADHD Symptomatology and Criminal Behavior During Adolescence Exploring the Mediating Role of School Factors

Prior research has shown that attention deficit/hyperactivity disorder (ADHD) relates to various negative outcomes in adolescence, including academic failure, behavioral problems at school, and criminal behavior. However, this line of research has generally failed to explore whether ADHD connects to criminal behavior through its effects on school factors. Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), this study finds that a retrospective account of ADHD symptomatology during childhood and early adolescence predicts weakened school attachment, lower grades, and higher risks for both out-of-school suspension and crime. School attachment, grades, and out-of-school suspension have the expected effects on crime among females and males. Among females, these school factors mediate the effects of ADHD symptomatology on crime. The effect of ADHD symptomatology on crime among males remains significant when controlling for school factors. Implications of the findings for policy and theory are discussed.

WITHDRAWN: Relative Deprivation, Absolute Deprivation, and Homicide: Testing an Interaction Between Income Inequality and Disadvantage

Both relative and absolute deprivation have effects on crime. These two concepts may be complementary, but much scholarship has treated them as separate. The present study assesses whether the effects of relative and absolute deprivation, measured as income inequality and disadvantage, respectively, interact in their effect on known homicide counts in U.S. counties. A multilevel regression model shows that there is a significant interaction between income inequality and disadvantage predicting homicide counts known to police. The plot of this interaction shows that when disadvantage is extremely high, increasing income inequality does not increase known homicides. The less disadvantage there is, the greater the effect of increasing income inequality on homicide counts in U.S. counties. This finding suggests that the effect of relative deprivation on known homicide is contingent on levels of absolute deprivation and vice versa. The implication of this finding is discussed.

An Examination of the Importance of Strain in the Cannabis Gateway Effect.

Gateway theory has been the source of much debate in both the research literature and public policy. Support for gateway sequencing has been mixed, especially in research that has considered the role of criminological variables in the etiology of substance use. For example, limited prior research has observed as important in gateway sequencing the effects of severe stressors. Data from the National Longitudinal Study of Adolescent to Adult Health are utilized to test gateway theory and examine whether severe stressors affect the relationship between frequency of cannabis use and later use of other illicit drugs (OIDs). Findings suggest that while frequency of cannabis use does increase the likelihood of later use of OIDs, this relationship may be the result of the common cause of experiencing severe stress. Implications of the findings are discussed.
