ADHD and criminality: A primer on the genetic, neurobiological, evolutionary, and treatment literature for criminologists

Objective

This state of the art review of 102 studies is a primer on ADHD and its major comorbidities for criminologists unfamiliar with the genetic, neurobiological, and evolutionary literatures.

Materials and methods

Neurological, genetic, medical, and criminal justice data bases were keyword searched for articles on ADHD and/or articles using ADHD as a major independent variable.

Results

ADHD is a disorder that is closely connected to externalizing behaviors, conduct problems, and criminal behavior across the life course.

Conclusions

To date, ADHD research has been carried out primarily by biomedical researchers and de-emphasized by criminologists whose training is overwhelmingly in the social sciences. The special expertise of criminologists in uncovering environmental correlates of antisocial behavior can benefit biomedical researchers who in turn can assist criminologists in uncovering the individual-level correlates of antisocial behavior.     

Black–white differences in positive outcome expectancies for crime: A study of male federal prison inmates

Purpose

This study was designed to assess whether black inmates hold more positive outcome expectancies for crime than white inmates in an effort to inform the debate on the nature of well documented differences in criminal involvement between blacks and whites.

Methods

Positive outcome expectancies for crime were measured in 393 black male inmates and 154 white male inmates housed in a medium security federal correctional institution using the Outcome Expectancies for Crime (OEC: Walters, 2003b) inventory.

Results

Black inmates reported significantly stronger positive outcome expectancies for crime than white inmates after controlling for preexisting group differences in age, education, marital status, confining offense, response style, general criminal thinking, and negative outcome expectancies for crime. Anticipation of social benefits for crime in the form of love, respect, and security were particularly salient in distinguishing between black and white inmates.

Conclusions

It is speculated that an interaction of motivational (high achievement motivation), structural (blocked economic opportunities), and cultural (peer reinforcement) factors may be responsible for black-white differences in crime with important implications for theory, research, and clinical practice.     

The ties that bind or the ties that break: Examining the relationship between visitation and prisoner misconduct

Purpose

Prior theory and research suggest that inmate visitation can reduce misconduct in prison. However, prior studies have not accounted for the longitudinal and heterogeneous nature of these experiences. This paper addresses this research gap by examining variation in visitation experiences and the relationship between patterns of visitation and misconduct.

Methods

Using a cohort of offenders incarcerated in Florida between 2000 and 2002, group-based trajectory model analyses were used to identify groups of inmates based on their visitation and misconduct patterns. Dual trajectory analysis was used to then assess the extent to which the development of visitation and misconduct patterns are interrelated.

Results

Visitation, and more consistent visitation in particular, is associated with less prison misconduct.

Conclusions

Visitation may reduce inmate misconduct. Implications for future research, theory, and policy are discussed.     

Violent criminals locked up: Examining the effect of incarceration on behavioral continuity

Purpose

The purpose of the current study was to determine whether, and the degree to which, inmates committing specific types of violent crimes in the community were prone to commit acts of violence while incarcerated.

Materials and methods

Data were collected from the Texas Department of Criminal Justice on the prison stock population and a restricted admissions cohort serving time during FY 2008.

Results

After controlling for pre-prison and post-conviction characteristics, crime of conviction retained a modest degree of influence on inmates’ propensity to commit dangerous rule violations in prison. Inmates convicted of assault, robbery and other miscellaneous violent crimes were more likely to commit dangerous rule infractions than inmates convicted of property crimes, supporting the behavioral continuity thesis. Inmates convicted of homicide were no more likely, and those convicted of sexual assault less likely, to commit dangerous rule violations in comparison to those convicted of property crimes.

Conclusions

The findings suggest that researchers and prison officials should not view all inmates convicted of one of a broad category of “violent crimes” in the community as being equivalent in their propensity for violence while incarcerated.     

Serious assaults on prison staff: A descriptive analysis

Objective

The current study sought to illuminate the patterns associated with serious inmate-on-staff assaults, as well as the characteristics of perpetrators and victims.

Material and methods

This study examined 79 assaults on prison staff requiring more than first aid treatment, perpetrated by 96 inmates, in a large state correctional department during a 14-month period (September 1, 2007 through October 31, 2008).

Results

These assaults were both infrequent (53 per 100,000 inmates annually) and progressively more infrequent as the severity increased (hospitalization for non-life threatening injury or required reconstructive surgery = 2.2 per 100,000 inmates annually; hospitalization for life-threatening injury = 0.5 per 100,000 inmates annually). Among staff victims, Black and female correctional officers were underrepresented. Inmate perpetrators who were younger, Black, prison gang members, and/or serving sentences for violent offenses were disproportionately represented among assailants.

Conclusions

The low overall rate of serious staff assaults attests to the level of professionalism and training in modern corrections departments. Nonetheless, situational factors uncovered in the current analysis suggest that particular circumstances increase the likelihood of staff assaults, hence the need for continued training and vigilance on the part of correctional staff that come in direct contact with inmates.     

Reporting violence to the police: Predictors through the life course

Scholarship focused on factors that influence police reporting has a long history in the literature. Yet we lack a complete understanding of how these factors differentially influence reporting by age.

Purpose

This paper aims to enhance our understanding of underreporting by investigating the relationship between reporting and age, and how this relationship differs by crime type. The study further investigates whether a variety of characteristics differentially influence reporting across the life course. Finally, the study asks how the nature of reporting varies by the victim's age.

Methods

National Crime Victimization Survey (NCVS) data were used to assess whether there are age-related differences in the factors influencing the rate and nature of police reporting.

Results

The findings suggest that the rate of reporting differs by crime type but that it generally increases throughout the life course. The influence of incident, victim, and offender characteristics on police reporting varies, not simply between juveniles and adults, but also between young and older adults. The proportion of incidents reported to police by the victim his/herself also continues to increase with age.

Conclusions

This suggests that disparities in police reporting cannot be reduced to juvenile-adult comparisons and should be studied across the full life course.     

Race group differences in prison victimization experiences

Purpose

To assess differences in victimization risk between African American and white, non-Latino inmates, and to estimate race group differences in the correlates of victimization.

Methods

Random samples totaling 2,403 African Americans and 3,150 whites were drawn from all state prisons in Ohio and Kentucky and all private prisons in Ohio (n = 46). Race-specific bi-level models of physical assaults and property thefts were estimated. Differences between race-specific models in the magnitude of regression coefficients for the same predictors and outcomes were compared.

Results

The odds of victimization by physical assault and by theft were significantly higher among whites compared to African Americans. Race group differences in the magnitude of several inmate level effects (e.g., age, sex, education, family status, officer “legitimacy”, custody score, visitation) were also significant, yet facility effects were similar for both groups.

Conclusions

Assessing differences in the victimization experiences of African American and white inmates is important for developing effective crime prevention strategies in prison. We examined the most comprehensive models of inmate victimization (including inmate socio-demographics, activities during confinement, perceptions of officers, facility characteristics, and officer perceptions of rule enforcement) for one of the largest samples of prisons to date.     

The Residual Career Patterns of Police Misconduct

Purpose

To explore the extent to which patterns of police misconduct, particularly residual career length (RCL) and residual number of offenses (RNO), change over time in theoretically expected ways, and to determine whether such career features can adequately predict future misconduct when compared to traditional Early Intervention (EI) system criteria.

Methods

This study employs retrospective, longitudinal data gathered for a large cohort of police officers followed for a significant portion of their career and uses personnel complaints as the primary indicator of police misconduct.

Results

Distributions of RCL and RNO are presented according to 4 criteria: year of experience, complaint number, time since the last complaint, and onset of first complaint. There was a decline in RCL and RNO with experience and onset of first complaint. While RCL declined by complaint number, RNO remained steady. This is also true of time since last complaint. Risk scores derived from RCL and RNO were moderately predictive of future misconduct, but fared better than those derived from standard EI system criteria.

Conclusion

EI systems do not adequately predict future misconduct, but there appears to be value in taking a broader view of complaint patterns of officers as a way of increasing predicative validity.     

On the relationship of past to future involvement in crime and delinquency: A behavior genetic analysis

Purpose

Criminologists have devoted much attention to identifying the factors that drive stability in antisocial behavior. This body of research has, however, overlooked the contributions of behavior genetic research. This study sought to blend behavior genetics with the different perspectives used by criminologists to explain stability.

Methods

Employing a behavioral genetic research design, the current study analyzed the correlation between adolescent and adulthood crime (a 13 year time span was covered between the two time points) among a sample of sibling pairs drawn from the National Longitudinal Study of Adolescent Health (Add Health).

Results

The findings revealed that genetic factors accounted for nearly all of the stability in offending behavior from adolescence to adulthood. Environmental factors (particularly, of the nonshared variety) accounted for the majority of the changes in offending.

Conclusions

The implications of these results for criminological research and theory are discussed.     

Incarceration, education and transition from delinquency

Purpose

Much of what is known regarding the transition away from crime is limited to young adulthood and specific life events and samples of non-serious offenders comprised mainly of white males.

Methods

The current study assesses the potential links between educational achievement, post-release schooling, and re-arrest for a cohort of 4,147 incarcerated youths drawn from 115 Florida juvenile institutions and followed for two years post-release.

Results

Incarcerated youths with higher levels of educational achievement are more likely to return to school after release, and those youths who returned to and attended school regularly were less likely to be rearrested within 12 and 24 months. Moreover, among youths who were rearrested, those youth who attended school regularly following release were arrested for significantly less serious offenses compared to youths who did not attend school or attended less regularly.

Conclusions

The study concludes with discussion of the importance of educational achievement as an important turning point for juvenile offenders as they transition into young adulthood.     

Procedural justice during police-citizen encounters: The effects of process-based policing on citizen compliance and demeanor

Purpose

Theories of procedural justice have facilitated the development of a process-based approach to policing which emphasizes the fairness of the manner in which the police exercise their discretion. The study examines whether procedurally fair behavior by the police affects two types of citizen behavior during encounters: citizen disrespect toward the police and citizen noncompliance with police requests.

Methods

This study uses data from systematic social observations of police-citizen encounters to examine procedural justice factors on citizen behavior. Because of the reciprocal nature of police-citizen interactions, an instrumental variable is used in the statistical analysis to help address the causal relationship between police force and citizen disrespect.

Results

The statistical analyses find limited support for procedural justice factors. Two types of procedurally fair behavior by the police, police demeanor and their consideration of citizen voice, are significant in reducing citizen disrespect and noncompliance, respectively.

Conclusion

Procedural justice factors have limited and inconsistent impacts on the two types of citizen behavior, and future research should address the limitations of this study and evaluate process-based policing with more data from social observations of police-citizen encounters.     

GENERAL STRAIN THEORY, PERSISTENCE, AND DESISTANCE AMONG YOUNG ADULT MALES

Purpose

Despite the surge in scholarly activity investigating the criminal career, relatively less attention has been devoted to the issue of criminal desistance versus persistence (until recently). The present study contributed to our understanding of this process by exploring the suitability of General Strain Theory (GST) for predicting changes in criminal activity across time.

Methods

Data from a longitudinal study of males in South Florida are examined using robust regression analyses.

Results

The core GST relationship, that changes in strain should predict changes in criminal activity, was supported, even after controlling for important adult social roles such as marriage, labor force participation, and education. While no support for the proposition that changes in self-esteem and social support moderate the strain-criminal desistance association was evinced, evidence was found that angry disposition, a measure of negative emotionality, moderated the association between change in chronic stressors and change in criminal activity.

Conclusions

While exploratory in nature, these findings demonstrate the utility of employing GST principles in studies of criminal desistance.     

Fear of crime and vulnerability: Using a national sample of Americans to examine two competing paradigms

Purpose

A prominent explanation of why certain groups of people fear crime more than others focuses on physical and social vulnerability. Some researchers have argued that physical vulnerability characteristics (e.g., gender, age, health) are more important in determining one's fear of crime while others have argued that social vulnerability characteristics (e.g., race and socioeconomic status) are more important.

Methods

We test the independence of the physical and social vulnerability characteristics through a nationally representative sample of Americans. Using a multilevel path modeling approach, we examine whether the physical or the social vulnerability explanation is more powerful in its explanation, or whether a combination of both vulnerabilities explains fear of crime.

Results

Results suggest that the two explanations are interdependent to some degree; with the direct effects of social vulnerability being most tied to physical indicators of vulnerability through indirect effects. To a lesser degree, the direct effects of physical vulnerability are also tied to fear of crime indirectly through indicators of social vulnerability.

Conclusions

The implications of these results are discussed.     

Cost-benefit analysis of reducing crime through electronic monitoring of parolees and probationers

Objective

The objective of this study was to estimate the benefits and costs of using electronic monitoring (EM) and home detention to reduce crime committed by parolees and probationers.

Method

Data from a national survey of state prison inmates was adjusted and used to estimate the number of crimes that would have been committed by all parolees and probationers over the course of one year in the absence of EM and home detention. The data were analyzed in combination with existing analyses of the effectiveness and costs of EM and home detention and the economic costs of crime to estimate the benefit-cost ratio of nationwide implementation of EM and home detention with all parolees and probationers.

Results

EM plus home detention could avert an estimated 781,383 crimes every year. The social value of the annual reduction in crime is $481.1 billion. Society would gain $12.70 for every dollar expended on the proposed intervention.

Conclusion

EM plus home detention could be an effective deterrent to crime and could have enormous social benefits, especially if it is applied early and saves what would otherwise be habitual offenders from a life of crime.     

The strains of maternal imprisonment: Importation and deprivation stressors for women and children

Purpose

This study links General Strain Theory, criminal justice models of inmate adaptation, and life course stress models to examine (1) the influence of importation and deprivation strains on maternal health while imprisoned; and (2) the intergenerational consequences of maternal strains for child outcomes.

Methods

Qualitative and quantitative data were gathered from an incarcerated sample of mothers in a Federal prison (n = 120). Qualitative data were used to identify strains in mothers' lives. Multivariate quantitative analyses were also conducted to test the associations of maternal importation and deprivation strains with maternal health problems and child subjective weathering, or a sense of growing up faster than one's peers.

Results

The deprivation strain of a lack of contact with the mother's minor child is positively associated with her mental and physical health problems and children's subjective weathering. Maternal importation strains in the form of childhood traumas also increase mental health problems and subjective weathering.

Conclusions

This study finds that maternal deprivation and importation strains are associated with mother and child adjustment. Reducing strains mothers face while imprisoned may benefit both inmates and families. Furthermore, deprivation strains are influential net of pre-imprisonment stressors.     

Testing Social Support Theory: A Multilevel Analysis of Recidivism

Purpose

Tests of social support theory have relied on aggregate crime rates as the outcome of interest, but such a focus ignores the potentially important macro-level processes and effects on individual-level behavior We thus perform the first multi-level investigation of social support theory.

Methods

Multilevel modeling is used to explore whether the two varieties of county-level social support - the presence of charitable organizations and AFDC expenditures - are associated with recidivism in a sample of Florida prison releasees.

Results

Results show that while social support explains little variation in individual-level recidivism, a combination of private and public social support may reduce the likelihood of reconviction for drug offenses.

Conclusion

Findings provide mixed evidence for the prospect that social support—whether governmental or nongovernmental—is associated with recidivism among recently-released inmates.     

First-time DWI offenders are at risk of recidivating regardless of sanctions imposed

Objective

Research demonstrates that punitive approaches to DWI employed by the judiciary have failed to significantly reduce recidivism. However, little is known about the deterrent effects of administrative and diversion sanctions. We examine whether such sanctions deter first-time DWI offenders.

Methods

We grouped combinations of administrative, judicial, and diversion sanctions routinely employed in the state of Maryland for processing drivers arrested for DWI into one of eight mutually exclusive disposition sequences. We applied this classification to Maryland drivers who had been licensed in the state and had precisely one DWI on their record prior to January 1, 1999. We then used a proportional hazards model to estimate the probability of remaining free of a new DWI during a 6-year period (January 1, 1999 - December 31, 2004) as a function of the disposition of the index violation, and of selected factors that could affect that probability.

Results

Drivers with a prior DWI were at relatively high risk of recidivating regardless of how they were sanctioned. Those who received administrative and alternative sanctions had a risk of recidivating similar to that of drivers who were convicted.

Conclusion

All dispositions sequences, not just convictions, indicate that first-time DWI offenders are at high risk of recidivating.     

Groups, gangs, and delinquency: Does organization matter?

Purpose

A consistent finding of research on delinquency has been that gang members show higher levels of delinquent behavior than non-gang members. However, research attempting to understand the mechanisms underlying this finding is lacking. The basic premise of the current article is that the level of organization found in delinquent groups and gangs matters in clarifying the relationship between membership and delinquency.

Methods

This article examined the association between organization and delinquency in a sample of 523 self-reported juvenile offenders from a high school survey conducted in the province of Quebec, Canada.

Results

The results showed that 1) there is clearly something special about membership in a gang that influences delinquency beyond the more general membership in a delinquent group; 2) the key to understanding finding lies, in part, in the level of organization found in gangs. Organization emerged as the most important factor associated with general delinquency, involvement in violence, and in drug supply offences, significantly (but not completely) reducing the effect of gang membership on delinquency.

Conclusions

Even if most delinquent associations show little signs of formal structure and organization, this study demonstrates the importance of organization as a key mechanism to understand the gang effect on delinquency.     

The impact of determinate sentencing on prisoner misconduct

Purpose

The shift from indeterminate to determinate punishment policies over the past three decades may have the unintended consequence of increasing prisoner misconduct due to the elimination or reduction of parole and earned gain-time to provide incentives for inmates to comply with institutional rules. This paper advances the existing scholarship addressing this issue.

Methods

Data on a cohort of 305,228 inmates admitted to prison in Florida over a twelve year period before and after the enactment of a “truth-in-sentencing” law in 1995 requiring all felons sentenced to prison to serve a minimum 85% of their sentence are examined to assess the impact of determinate punishment on whether inmates commit disciplinary infractions and the frequency of misconduct.

Findings

The data show that determinate punishment has had the unintended consequence of significantly increasing the level of inmate misconduct in general and across different types of misconduct; violent, property, and disorderly.

Conclusion

The findings indicate that states which currently have or are considering the implementation of determinate sentencing should examine potential changes in policies and practices to alleviate the impact of reductions in inmate incentives to abide by institutional rules.
