SELF‐CONTROL THROUGH EMERGING ADULTHOOD: INSTABILITY, MULTIDIMENSIONALITY, AND CRIMINOLOGICAL SIGNIFICANCE

This study assesses self-control theorys stability postulate. We advance research on self-control stability in three ways. First, we extend the study of stability beyond high school, estimating GBTMs of self-control from ages 10 to 25. Second, drawing on advances in developmental psychology and social neuroscience, especially the dual systems model of risk taking, we investigate whether two distinct personality traits--impulsivity and sensation seeking--often conflated in measures of self-control, exhibit divergent developmental patterns. Finding that they do, we estimate multitrajectory models to identify latent classes of co-occurring developmental patterns. We supplement GBTM stability analyses with hierarchical linear models and reliable variance estimates. Lastly, using fixed effects models, we explore whether the observed within-individual changes are associated with changes in crime net of overall age trends. These ideas are tested using five waves of data from the Family and Community Health Study. RESULTS suggest that self-control is unstable, that distinct patterns of development exist for impulsivity and sensation seeking, and that these changes are uniquely consequential for crime. We conclude by comparing our findings with extant research and discussing the implications for self-control theory. Language: en

THE CODE OF THE STREET AND INMATE VIOLENCE: INVESTIGATING THE SALIENCE OF IMPORTED BELIEF SYSTEMS†

Scholars have long argued that inmate behaviors stem in part from cultural belief systems that they import with them into incarcerative settings. Even so, few empirical assessments have tested this argument directly. Drawing on theoretical accounts of one such set of beliefs-the code of the street-and on importation theory, we hypothesize that individuals who adhere more strongly to the street code will be more likely, once incarcerated, to engage in violent behavior and that this effect will be amplified by such incarceration experiences as disciplinary sanctions and gang involvement, as well as the lack of educational programming, religious programming, and family support. We test these hypotheses using unique data that include measures of the street code belief system and incarceration experiences. The results support the argument that the code of the street belief system affects inmate violence and that the effect is more pronounced among inmates who lack family support, experience disciplinary sanctions, and are gang involved. Implications of these findings are discussed.

PULLING BACK THE CURTAIN ON HERITABILITY STUDIES: BIOSOCIAL CRIMINOLOGY IN THE POSTGENOMIC ERA

Unfortunately, the nature-versus-nurture debate continues in criminology. Over the past 5 years, the number of heritability studies in criminology has surged. These studies invariably report sizeable heritability estimates (∼50 percent) and minimal effects of the so-called shared environment for crime and related outcomes. Reports of such high heritabilities for such complex social behaviors are surprising, and findings indicating negligible shared environmental influences (usually interpreted to include parenting and community factors) seem implausible given extensive criminological research demonstrating their significance. Importantly, however, the models on which these estimates are based have fatal flaws for complex social behaviors such as crime. Moreover, the goal of heritability studies--partitioning the effects of nature and nurture--is misguided given the bidirectional, interactional relationship among genes, cells, organisms, and environments. This study provides a critique of heritability study methods and assumptions to illuminate the dubious foundations of heritability estimates and questions the rationale and utility of partitioning genetic and environmental effects. After critiquing the major models, we call for an end to heritability studies. We then present what we perceive to be a more useful biosocial research agenda that is consonant with and informed by recent advances in our understanding of gene function and developmental plasticity.

Interpersonal Racial Discrimination, Ethnic-racial Socialization, and Offending: Risk and Resilience among African American Females

Evidence is accumulating that interpersonal racial discrimination is criminogenic and ethnic-racial socialization (ERS) practices provide resilience. This research, however, has largely focused on black males. We address this gap by exploring these risk and resilience processes among black females. Drawing on Simons and Burt’s social schematic theory and research on adaptive cultural practices in African American families, this study investigates how interpersonal racial discrimination increases the risks of crime among females and whether familial ERS provides resilience. After focusing on females, we also compare the findings among females to those for males to shed light on gender differences. We examine these questions using panel data from the Family and Community Health Study, a survey of black families first surveyed in 1999 and at roughly two-year intervals thereafter. Consistent with prior work, we find a strong effect of racial discrimination on an increase in crime, with the bulk of this effect being mediated by the criminogenic knowledge structure. Although one of the two forms of ERS examined—cultural socialization—did not reduce the criminogenic effects of racial discrimination, preparation for bias exerted a strong protective effect. Comparing the findings to that for males revealed that preparation for bias attenuated the criminogenic effects of racial discrimination for both males and females, but it did so in gendered ways. This study fills a gap in our understanding of the criminogenic effects of discrimination among black females, supporting a social schematic theory’s explanation of the effects of racial discrimination on crime. In addition, findings highlight protective cultural practices in African American families, especially preparation for bias.

Impact of child sex abuse on adult psychopathology: A genetically and epigenetically informed investigation

Genetic, environmental, and epigenetic influences and their transactions were examined in a sample of 155 women from the Iowa adoptee sample who had been removed from their biological parents shortly after birth and assessed when participants were an average of 41.10 years old. We observed an interactive effect of child sex abuse (CSA) and biological parent psychopathology (i.e., genetic load) on substance abuse as well as a main effect of CSA on substance abuse in adulthood. We also observed main effects of CSA and genetic load on depression and on antisocial characteristics. As predicted, CSA, but not genetic load or later substance abuse, was associated with epigenetic change. In addition, the interaction between genetic load and CSA predicted epigenetic change, indicating a potential genetic basis for a differential impact of CSA on epigenetic change. Finally, epigenetic change partially mediated the effect of CSA on antisocial characteristics. The results suggest the relevance of genetic and epigenetic processes for future theorizing regarding marital and family precursors of several forms of adult psychopathology. Implications for preventive intervention are discussed.

Self-Control, Thrill Seeking, and Crime Motivation Matters

Self-control theory (SCT), as a control theory, assumes that the pleasures gained from crime are equally obvious and attractive to all. This study brings a consideration of crime as a process into SCT, recognizing that the sensations inherent in offending may not be equally attractive to everyone. In doing so, we test the theory’s equal motivation assumption, bringing a consideration of individual differences in thrill seeking to the fore. Drawing on theory and research on the personality characteristic thrill seeking, we hypothesize that thrill seeking and self-control have independent influences on offending: that motivation to the process of crime matters. In addition, we investigate whether the effects of self-control are contingent on levels of thrill seeking, in part because high thrill seekers are less averse to the process of risk. These hypotheses are tested using data from the Family and Community Health Study, a sample of roughly 700 African American youth and their families. A new measure of self-control is employed in tandem with an existing attitudinal measure of self-control and thrill seeking. Consistent with hypotheses, the results suggest that self-control and thrill seeking have largely independent influences on offending and that the effects of self-control are contingent on levels of thrill seeking. These results provide further evidence that SCT’s assumption of equal motivation to crime is untenable, as individual differences in the personality characteristic thrill seeking influence the likelihood of offending.

Mechanisms That Link Parenting Practices to Adolescents' Risky Sexual Behavior: A Test of Six Competing Theories.

Risky sexual behavior, particularly among adolescents, continues to be a major source of concern. In order to develop effective education and prevention programs, there is a need for research that identifies the antecedents of such behavior. This study investigated the mediators that link parenting experiences during early adolescence to subsequent risky sexual behaviors among a diverse sample of African American youth (Nxa0=xa0629, 55xa0% female). While there is ample evidence that parenting practices (e.g., supportive parenting, harsh parenting, parental management) are antecedent to risky sexual behavior, few studies have examined whether one approach to parenting is more strongly related to risky sex than others. Using a developmental approach, the current study focused on factors associated with six theories of risky sexual behavior. While past research has provided support for all of the theories, few studies have assessed the relative contribution of each while controlling for the processes proposed by the others. The current study addresses these gaps in the literature and reports results separately by gender. Longitudinal analyses using structural equation modeling revealed that the mediating mechanisms associated with social learning and attachment theories were significantly related to the risky sexual behavior of males and females. Additionally, there was support for social control and self-control theories only for females and for life history theory only for males. We did not find support for problem behavior theory, a perspective that dominates the risky sex literature, after controlling for the factors associated with the other theories. Finally, supportive parenting emerged as the parenting behavior most influential with regard to adolescents’ risky sexual behavior. These results provide insight regarding efficacious approaches to education and preventative programs designed to reduce risky sexual behaviors among adolescents.

Genetic moderation of contextual effects on negative arousal and parenting in African-American parents.

A three-stage context amplification model was tested with a sample of 345 African-American parent-child dyads. The model combined the conceptual structure of stress generation with recent findings regarding genetic susceptibility. Because the 7R + allele of the dopamine transporter (DRD4) has the potential to enhance contextual priming and arousal, this allele was examined as a potential moderator of each stage of the amplification process. Particular attention was given to the hypothesized influence of parental negative arousal on valence of parent-child interactions. The literature on genetic susceptibility led to the hypothesis that DRD4 would moderate each stage of the model in a for better or for worse manner. The model was partially supported. DRD4 moderated effects at all three stages of the model and, as hypothesized, DRD4 moderated contextual effects on negative arousal in a for better or for worse manner. Effects on parent-child interaction, however, were moderated in a for worse manner only. These results indicate that parenting interactions may amplify the effects of positive and negative contexts in a stress-generating manner, and that a susceptibility framework captures the way in which DRD4 moderates the impact of context on negative arousal.

Factors linking childhood experiences to adult romantic relationships among African Americans.

It is well known that a high-quality relationship with a romantic partner is related to a variety of positive outcomes associated with health and well-being. Establishing such relationships is an important developmental task for young adults, and past research indicates that there is a link between experiences in the family of origin and the success of later intimate relationships. It has been suggested that this association can be explained by the acquisition of social competencies (e.g., emotions, schemas, traits) that are acquired during childhood in the family of origin and, in turn, influence interaction with adult romantic partners. The current study builds on this foundation by identifying particular competencies expected to explain the association between childhood exposure to supportive and harsh parenting and later patterns of interaction with romantic partners. Specifically, we examine anger management, attachment style, hostile attribution bias, and self-control as potential mediators using prospective, longitudinal data from a sample of 345 African American young adults. Results from structural equation modeling indicate that each of the mediators in our study accounts for a significant portion of the effect of parenting on the quality of adult romantic relationships, although the constructs linking parenting to warm interactions with romantic partners are somewhat different from those that link parenting to hostile interactions with romantic partners. Even after accounting for the effect of the mediators, there is still a direct effect of parenting on both warm/loving and hostile/aggressive interactions with romantic partner. Implications for theory and practice are discussed.

INCORPORATING ROUTINE ACTIVITIES, ACTIVITY SPACES, AND SITUATIONAL DEFINITIONS INTO THE SOCIAL SCHEMATIC THEORY OF CRIME.

Simons and Burts (2011) social schematic theory (SST) of crime posits that adverse social factors are associated with offending because they promote a set of social schemas (i.e., a criminogenic knowledge structure) that elevates the probability of situational definitions favorable to crime. This study extends the SST model by incorporating the role of contexts for action. Furthermore, the study advances tests of the SST by incorporating a measure of criminogenic situational definitions to assess whether such definitions mediate the effects of schemas and contexts on crime. Structural equation models using 10 years of panel data from 582 African American youth provided strong support for the expanded theory. The results suggest that childhood and adolescent social adversity fosters a criminogenic knowledge structure as well as selection into criminogenic activity spaces and risky activities, all of which increase the likelihood of offending largely through situational definitions. Additionally, evidence shows that the criminogenic knowledge structure interacts with settings to amplify the likelihood of situational definitions favorable to crime.
