General theories of crime have frequently been used to explain a variety of offending and victimization experiences for a wide range of samples. However, feminist criminologists question whether the same causal mechanisms exert similar effects for males and females—a criticism that points to the need for sex-specific analyses. Toward that end, this dissertation examines variables derived from several different general theories of crime in three separate studies. Each of the studies uses split-sample analyses to investigate potential sex-based differences. The first study uses three-level meta-analytic methods to determine if predictor variables derived from general theories explain victimization for both adolescent males (n = 138,848) and adolescent females (n = 176,611). Additionally, it examines both within-dataset and between-dataset differences. The second study uses a sample of high school students in Arizona (n = 2,738 males, n = 2,932 females). It examines the role of parental social ties in explaining the overlap of adolescent dating violence (ADV) offending and victimization. The third study uses two waves of a longitudinal dataset of high-risk adolescents (n = 182 males, n = 203 females). It focuses on the relationship between negative emotions and delinquency, and the role of avoidant coping. In each of the studies, both gender-neutral and gender-specific explanations of offending and victimization were found. In the first study, while predictor variables derived from criminological theory explained victimization for both males and females, larger effect sizes were found for risky lifestyle variables. In the second study, an overlap between ADV offending and victimization was found for both males and females, and social ties explained some of the overlap. However, paternal attachment was only significant for females, and involvement was only significant for males. In the third study, avoidant coping was associated with an increase in substance abuse, and anger was associated with an increase in violent behavior for both males and females. Avoidant coping partially mediated the relationship between anger and substance use, but only for males. Implications for practice and future research are discussed.

Academic deviance is a potentially detrimental behavior for students and universities alike in that it causes credit to be given to individuals where it is not due. Furthermore, it is a common occurrence, with around half of college students admitting to engaging in this behavior at least once. Therefore, the purpose of this study is to investigate the relationship between perfectionism, strain, and academic deviance. In doing this, this study uses data from a primary data collection effort in Arizona State University, with a final sample of 696 students, to answer three research questions: Are there differences in the likelihood of engaging in academic deviance by maladaptive perfectionists, adaptive perfectionists, and non-perfectionists? Are there differences in the perceptions of the wrongness of academic deviance between maladaptive perfectionists, adaptive perfectionists, and non-perfectionists? Are there differences in how context dependent maladaptive perfectionists, adaptive perfectionists, and non-perfectionists view academic deviance the wrongness of academic deviance? Ordered logistic regression are used to access these research questions. Results suggest that neither perfectionism nor strain were a significant factor in determining the likelihood that a participant would engage in an academically deviant behavior, or how wrong they believed that behavior to be. However, perfectionism did seem to have a mild impact on how context dependent individuals felt the wrongness of their behaviors, meaning that if the cause of the strain was due to the professor’s actions, students viewed academic deviance as less wrong, and self-control explained at least part of this effect. Strain, on the other hand, did not have a significant effect. Overall, the results suggest some legitimacy to the use of general strain theory to explain the potential relationships, given the relationship between perfectionism and context dependency. Additionally, the results support policy implications designed to reduce maladaptive thoughts and subsequently academic deviance, such as cognitive behavioral therapy (CBT). Future research should examine the link between perfectionism and other types of academic strain.

Given the many changes taking place within the juvenile justice system, it is not surprising that there are clashing opinions about those changes. The development of research surrounding adolescents and juvenile offenders has grown substantially in the past few decades, but now there are many legislative changes taking place. Throughout these changes, there are several colliding opinions. Should juvenile offenders be sentenced in a more lenient fashion? Should justice policies match developmental processes for juveniles? The different stances on these issues have caused some serious public disagreement. In light of these recent events, research gauging public opinions regarding these concepts has slowly grown. In order to take a look at opinions regarding juvenile offenders and their justice treatment, in this study, I examined the differences in opinion between juvenile and adult offenders. The goal of this survey was to help gain an understanding about the public’s perceptions of juvenile offenders and how that relates to current issues with both research and policy.

The way the public perceives law enforcement influences how communities function. Identifying how individuals develop their perceptions of law enforcement is critically important. Mainly, their experiences with officers determine how perceptions of law enforcement are developed. Analyzing perceptions of law enforcement can help people understand relationships that officers have with community members and determine the type of impact that officers have on certain populations such as the youth. This study examines youth perceptions of law enforcement. The youths’ perception of police is an important perception to analyze. It is important because their perceptions have the power to create change or influence other people their age. It has been seen that the youth “create meaningful institutional change in their communities”. The research and findings on perceptions of law enforcement are important because they could help explain whether there is a correlation between crime rates in the community and perceptions of law enforcement from community members. It can also help identify how much the youth population is willing to rely on law enforcement and whether they trust and respect them. The youth are exposed to factors in their community that can influence certain attitudes and perspectives. In this research, a study from Elementary schools in Compton, CA is analyzed to identify youth perceptions of law enforcement. The research questions addressed are: Is there any correlation between crime rates in the community and perceptions of law enforcement? Can a program implemented into schools improve youth perceptions of law enforcement? How much are the youth willing to rely on law enforcement?

Although child welfare services are anticipated, in part, to lessen the negative

influence of maltreatment on childhood and adolescent development, there is evidence

that involvement in the foster care system negatively affects adolescent substance

use. Within the literature, limited empirical research has emerged in regard to this issue.

The present study aims to fill this critical gap in the literature by examining the

association between baseline biological, psychological, and social risk and protective

factors on adolescent involvement in substance use, and frequency of substance use, over

a period of 24 months for foster care involved youth. Furthermore, the present study

compares substance use behaviors between youth with differing experiences of

maltreatment subtypes and severity levels. Data come from VOYAGES, a longitudinal

study of older adolescents in the custody of the Missouri Children’s Division for foster

care services. The current analysis reports on those youth who completed both the

baseline and the final interview (N=323). Key findings include significant associations

between baseline peer substance use, lowered levels of school commitment, mentorship,

and familial support with later adolescent substance use. Overall, the existence of

numerous individual risk factors far outweighs the potential of protective factors

buffering against subsequent substance use in the current study. The foster care system,

although well-intentioned, potentially barricades individuals from successfully navigating

through adolescence and early adulthood without engaging in risky behaviors such as

substance use. Given the high prevalence of substance use among those placed in the

care of the foster care system, prevention efforts for this population requires an improved

understanding of psychosocial risk and protective factors.

Criminological theories have long incorporated personality traits as key explanatory factors and have generally relied on assumptions of trait stability. However, growing evidence from a variety of fields including criminology, psychology, and neurobiology is demonstrating that personality traits are malleable over the life-course, and substantial individual variation exists in the developmental patterns of personality traits over time. This research is forcing criminologists to consider how and why “enduring” individual characteristics may change over the life course in ways that are meaningfully related to offending. Two traits that have been consistently linked to offending and conflated in key criminological theories (i.e. Gottfredson and Hirschi’s self-control theory), impulsivity and sensation seeking, have recently been shown to be independent personality traits with different normative maturational timetables and biological underpinnings. This dissertation extends this work by examining developmental patterns of impulsivity and sensation seeking and social sources of variation in these traits with the Family and Community Health Survey, a longitudinal data set that consists of approximately 900 African American youth and their families followed from late childhood to their late-twenties. Multiple longitudinal modeling methods are employed (hierarchical linear modeling and group-based trajectory modeling) to address this research agenda. Results from this dissertation lead to four broad conclusions. First, and in support of existing research, there is substantial variability in developmental trajectories of impulsivity and sensation seeking. Average developmental trajectories of these traits greatly mask the degree of individual variability in developmental patterns that exists. Second, social factors are significantly associated with levels of impulsivity and sensation seeking. Socio-environmental experiences characterized by hostility and unsupportiveness are generally associated with elevated levels of impulsivity and sensation seeking while socio-environmental experiences characterized by warmth and supportiveness are associated with lower levels of impulsivity and sensation seeking. Third, sex differences in developmental patterns of impulsivity are nonexistent while sex differences in developmental patterns of sensation seeking are significant. Finally, with few exceptions, predictors of trait levels operate in a general fashion such the same factors typically explain both male and female trait levels and produce similar effects on impulsivity and sensation seeking.
