The Empirical Status of Social Learning Theory: A Meta‐Analysis

Social learning theory has remained one of the core criminological paradigms over the last four decades. Although a large body of scholarship has emerged testing various propositions specified by the theory, the empirical status of the theory in its entirety is still unknown. Accordingly, in the present study, we subject this body of empirical literature to a meta‐analysis to assess its empirical status. Results reveal considerable variation in the magnitude and stability of effect sizes for variables specified by social learning theory across different methodological specifications. In particular, relationships of crime/deviance to measures of differential association and definitions (or antisocial attitudes) are quite strong, yet those for differential reinforcement and modeling/imitation are modest at best. Furthermore, effect sizes for differential association, definitions, and differential reinforcement all differed significantly according to variations in model specification and research designs across studies. The implications for the continued vitality of social learning in criminology are discussed.     

Stopping the revolving door: a meta-analysis on the effectiveness of interventions for criminally involved individuals with major mental disorders

Faced with high and increasing rates of mental disorder within the criminal justice system (CJS), a range of interventions have been implemented in an effort to prevent continued involvement in criminal activities among this population. A meta-analytic review was undertaken to consider the effectiveness of interventions for criminally involved adults with a mental disorder targeting either improved criminal justice or mental health outcomes. Furthermore, characteristics that were hypothesized to predict better outcomes were examined. Studies that considered sex offender interventions, or focused solely on antisocial personality, intellectual and cognitive, or substance use disorders were excluded. Results assuming a fixed-effects model combining 37 effect sizes from 25 studies (N = 15,678) support the effectiveness of these interventions in terms of reductions in any CJS involvement (d = 0.19 excluding one outlier). Interventions had no significant effect on an aggregate mental health outcome (d = 0.00). However, when considering distinct mental health outcomes, intervention participants had significantly better functioning (d = 0.20) and fewer symptoms (d = 0.12). There were no significant effects of the interventions on mental health service or medication use. Moderator analyses identified seven sample, intervention, and design characteristics that were related to the magnitude of the effect sizes for criminal justice outcomes, and suggest implications for service provision, policy, and research. Results suggested some relationship between intervention effects on mental health and criminal justice reinvolvement, although future research is needed in this area, especially given the absence of mental health outcome data in many studies.     

Predicting daily-life antisocial behaviour in institutionalized adolescents with Transgression-related Implicit Association Tests

This study investigated whether implicit attitude (IA) and implicit self-concept (ISC) towards transgression predicted daily-life antisocial behaviour (ASB) in institutionalized adolescents. Eighty-seven adolescents completed two Implicit Association Tests (IAT) assessing IA and ISC towards transgression, and reported four times a day during eight days the intensity of their ASB. Staff members concurrently reported the intensity of each adolescent’s ASB. Adolescents filled in the Inventory for Callous-Unemotional Traits and answered a semi-structured interview assessing conduct disorder. Multilevel regression analyses confirmed that adolescents’ ISC towards transgression significantly predicted their self - and staff-reported ASB over and above conduct disorder and callous-unemotional traits. However, adolescents’ IA towards transgression did not predict their ASB. Results indicate that ISC towards transgression is a reliable predictor of daily-life ASB in institutionalized adolescents. These results suggest that transgression-related ISC represents a promising target for ASB prevention in institutionalized adolescents.     

Preliminary Study of Testosterone and Empathy in Determining Recidivism and Antisocial Behavior

Recidivism, repeated criminal behavior after conviction and correction of prior offenses, is a costly problem across the nation. However, the contribution of empathy in determining the risk of recidivism has received limited attention, although lack of empathy has been related to antisocial personality disorder in various studies. Studies linked testosterone to aggression, antisocial behavior, and criminality, and evidence support hormonal connections between empathy and aggression. Adult male prison inmates convicted of violent or nonviolent offenses were included in a cross‐sectional study of empathy, antisocial behavior, salivary testosterone, and recidivism. Subjects underwent criminal history, Empathy Quotient, Levenson Self‐Report Psychopathy Scale, Beck Depression Inventory, Spielberger State‐Trait Anxiety Inventory, and salivary testosterone assays. Bivariate analyses indicated multiple correlations between variables. Multivariate modeling analyses found a significant relationship between self‐reported conviction number and psychopathy scale score (p = 0.013). These preliminary results suggest avenues of investigation of factors contributing to recidivism risk.     

An assessment of personality disorders with the Five-Factor Model among Belgian inmates

Many international studies report a high prevalence of personality disorders among inmates on the basis of (semi)-structured diagnostic interviews. The present study proposes a self-reported evaluation of personality disorders using the NEO PI-R. The sample consists of 244 male and 18 female inmates (N=262) who were psychologically assessed. The analysis of the five psychological domains shows that the French-speaking Belgian inmates are as stable, as extroverted, more closed, more agreeable and more conscientious than the normative sample. The NEO PI-R facets are also analyzed. The mean Cohen's d (.26) is small. Two personality disorders have medium effect sizes: obsessive compulsive personality disorder (high) and histrionic personality (low). Small effect sizes exist for antisocial personality (low), psychopathy (low), narcissistic personality (low), schizoid personality (high) and borderline personality (low). In our view, the context of the assessment can partially explain these results but not entirely. The results do not confirm previous studies and question the high rates of psychiatric prevalence in prison.     

The Relationship Between Mental Disorders and Types of Crime in Inmates in a Brazilian Prison

This cross‐sectional study conducted in prisons in the city of Salvador, Bahia, Brazil, investigated the association between the presence of psychiatric disorders in 462 prisoners and the types of crimes committed by them. Psychiatric diagnosis was obtained by means of the Brazilian Portuguese version of the Mini‐International Neuropsychiatric Interview. A statistically significant association was found between some psychiatric disorders and specific groups of crime: lifelong substance addiction with sex crimes and homicide; antisocial personality disorder with robbery and with kidnapping and extortion; borderline personality disorder with sex crimes; and lifelong alcohol addiction with fraud and conspiracy and with armed robbery and murder. It was concluded that the mental disorders considered more severe (psychosis and bipolar disorder) were not associated with violent crimes, suggesting that the severity of the psychotic disorder may be the factor that has caused psychosis to be associated with violent crimes in previous studies.     

STRUCTURAL MODELS OF PERSONALITY AND THEIR RELATION TO ANTISOCIAL BEHAVIOR: A META‐ANALYTIC REVIEW*

The authors argue that the concept of personality has much to offer the field of criminology. To this end, they used meta‐analytic techniques to examine the relations between antisocial behavior defined relatively broadly and four structural models of personality: Eysenck's PEN model, Tellegen's three‐factor model, Costa and McCrae's five‐factor model (FFM), and Cloninger's seven‐factor temperament and character model. A comprehensive review of the literature yielded 59 studies that provided relevant information. Eight of the dimensions bore moderate relations to antisocial behavior; the dimensions could all be understood as measures of either Agreeableness or Conscientiousness from the FFM. The implications of these findings for future research are considered.     

A Large-Scale Meta-Analysis Relating the Hare Measures of Psychopathy to Antisocial Conduct

The present meta-analysis integrated effect sizes from 95 non-overlapping studies (N=15,826) to summarize the relation between Hare Psychopathy Checklists and antisocial conduct. Whereas prior meta-analyses focused on specific subdomains of the literature, we used broad inclusion criteria, incorporating a diversity of samples, settings, methodologies, and outcomes in our analysis. Our broad perspective allowed us to identify general trends consistent across the entire literature and improved the power of our analyses. Results indicated that higher PCL Total, Factor 1 (F(1)), and Factor 2 (F(2)) scores were moderately associated with increased antisocial conduct. Study effect sizes were significantly moderated by the country in which the study was conducted, racial composition, gender composition, institutional setting, the type of information used to score psychopathy, and the independence of psychopathy and transgression assessments. However, multiple regression analyses indicated that the information used to assess psychopathy did not have a unique influence on effect sizes after accounting for the influence of other moderator variables. Furthermore, racial composition of the sample was related to the country in which the study was conducted, making it unclear whether one or both of these moderators influenced effect sizes. We provide potential explanations for the significant findings and discuss implications of the results for future research.     

Aggression and rule-breaking: Heritability and stability of antisocial behavior problems in childhood and adolescence

Purpose

This twin study examined the structure of genetic and environmental influences on aggression and rule-breaking in order to examine change and stability across the span of childhood to mid-adolescence.

Methods

Behavioral assessments were conducted at two time points: age 9–10 years and 14–15 years. Using behavioral genetics biometric modeling, the longitudinal structure of influences was investigated.

Results

Aggression and rule-breaking were found to be influenced by a latent common factor of antisocial behavior (ASB) within each wave of data collection. The variance in the childhood-age common factor of ASB was influenced by 41% genetics, 40% shared environment and 19% nonshared environment. In adolescence, 41% of variance in the common factor were novel and entirely genetic, while the remainder of variance was stable across time. Additionally, both aggression and rule-breaking within each wave were found to have unique influences not common across subscales or across waves, highlighting specificity of genetic and environmental effects on different problem behaviors at both ages.

Conclusions

This research sheds light on the commonality of influences on different forms of antisocial behavior. Future research into interventions for antisocial behavior problems in youth could focus on adolescence-specific environmental influences.     

Psychopathy,Conduct Disorder,and Stigma: Does Diagnostic Labeling Influence Juvenile Probation Officer Recommendations?

This study investigated the potential influence of labeling a juvenile as psychopathic. Juvenile probation officers (JPOs; N = 260) rendered hypothetical recommendations based on eight mock psychological evaluations. The evaluations varied the presence of two diagnostic criteria (antisocial behavioral history and psychopathic personality traits) and diagnostic labels (psychopathy, conduct disorder, no diagnosis) in order to distinguish criterion effects from labeling effects. The diagnostic criteria of antisocial behavior had a substantial effect on JPO recommendations (effect sizes .50–.79), while the diagnostic criteria of psychopathic personality traits had a more limited effect. Surprisingly, diagnostic labels had little effect, and there were no appreciable differences between conduct disorder and psychopathy diagnoses. These findings illustrate the importance of distinguishing diagnostic criterion effects from diagnostic labeling effects.     

REVISITING THE CRIMINOLOGICAL CONSEQUENCES OF EXPOSURE TO FETAL TESTOSTERONE: A META‐ANALYSIS OF THE 2D:4D DIGIT RATIO*

As criminology has become more interdisciplinary in recent years, biosocial criminology has earned a place at the table. Although this perspective comes in many forms, one important proposition has gained increasing attention: that the 2D:4D finger digit ratio—a purported physical biomarker for exposure to fetal testosterone—is related to criminal, aggressive, and risky/impulsive behavior. Strong claims in the literature have been made for this link even though the findings seem to be inconsistent. To establish the empirical status of this relationship, we subjected this body of work to a meta‐analysis. Our multilevel analyses of 660 effect size estimates drawn from 47 studies (14,244 individual cases) indicate a small overall effect size (mean r = .047). Moderator analyses indicate that this effect is rather “general” across methodological specifications—findings that are at odds with theoretical propositions that specify the importance of exposure to fetal testosterone in predicting criminal and analogous behavior later in life. We conclude with a call for exercising caution over embracing the findings from one or two studies and instead highlight the importance of systematically organizing the full body of literature on a topic before making decisions about what does, and what does not, predict criminal and analogous behavior.     

Are There Ethnic Differences in Levels of Psychopathy? A Meta-Analysis

Although considerable research on psychopathy has been conducted over the past 30 years, relatively few studies have examined key issues related to potential ethnic differences in this constellation of socially maladaptive personality traits. Given recent sociopolitical and scientific developments, an issue of considerable debate is whether Black individuals possess "more" traits of psychopathy than do Whites. To address this issue, a meta-analysis of differences between these groups' scores on the Psychopathy Checklist--Revised (PCL-R; Hare, 1991) was performed, using 21 studies (N = 8,890) of correctional, substance abuse, and psychiatric samples. Blacks exceeded Whites by an average of less than 1 point on the PCL-R total score. Effect sizes for core interpersonal and affective traits of psychopathy (Factor 1) were sufficiently homogeneous to clearly interpret, although other features manifested statistically significant heterogeneity. Our finding that Blacks and Whites do not meaningfully differ in their levels of core psychopathic traits is consistent with community-based findings for self-report measures of psychopathy and clinical diagnoses of antisocial personality disorder.     

Personality traits,personality disorders and sensational interests in mentally disordered offenders

Purpose. Sensational interests (e.g. an interest in the occult or the methods of violence) in mentally disordered offenders are claimed to signify greater risk of psychopathology, but evidence to support this view is slight. Methods. The relationships between self‐reported DSM‐IV personality disorder (PD), general personality traits and sensational interests were examined in 155 of 167 consecutively referred offenders to a forensic psychology service. The subscales of the PD and personality trait measures were reduced to the four basic PD/trait dimensions (asocial, antisocial, anxious and anankastic) using confirmatory factor analysis. Results. Those high on the ‘antisocial’ factor (which was primarily defined by low Agreeableness, low Conscientiousness, and substantial elements of Paranoid, Antisocial and Borderline PD) were more interested in ‘violent‐occult’ and militaristic topics. Conclusions. The aspects of the antisocial factor primarily associated with an interest in sensational and potentially violent topics cover a wide range of putative disorders. However, the factors reflecting asocial, anxious or anankastic disorders do not show a reliable association with measures of sensational interests. These results suggest that the personality dimensions reflecting an interest in ‘sensational’ topics in mentally disordered offenders are relatively specific.     

ROMANTIC PARTNERS' INFLUENCE ON MEN'S LIKELIHOOD OF ARREST IN EARLY ADULTHOOD*

Female romantic partners' influence on official crime occurrence for men across a 12‐year period in early adulthood was examined within a comprehensive dynamic prediction model, including both social learning and social control predictors. We hypothesized that relationship stability, rather than attachment to partner, would be associated with reduced likelihood of crime, whereas women's antisocial behavior would be a risk factor, along with deviant peer association. Models were tested on a sample of at‐risk men [the Oregon Youth Study (OYS)] using zero‐inflated Poisson (ZIP) modeling predicting 1) arrest persistence (class and count) and 2) arrest onset class. The findings indicated that women's antisocial behavior was predictive of both onset and persistence of arrests for men and that deviant peer association was predictive of persistence. Relationship stability was protective against persistence.     

Alcohol dependence and criminal behavior: preliminary results of an association study of environmental and genetic factors in an italian male population

The aim of this study is to propose an innovative approach evaluating the connection between alcohol use disorders and criminal behavior. The research, structured as a case–control study, was based on the analysis of environmental (social variables) and genetic factors (single nucleotide polymorphisms of glutamic acid decarboxylase) in a population (N = 173) of Italian alcohol‐dependent men. Group 1 (N = 47, convicted subjects) was compared with Group 2 (N = 126, no previous criminal conduct). Grade repetition, work problems, and drug problems were statistically associated with criminal behavior. Having daily family meals together and having children were inversely related to convictions. The genotype distribution of the two groups was similar. The association between environmental factors and antisocial behavior confirms previous findings in the literature. The lack of genetic association does not exclude the role of the gamma‐aminobutyric acid (GABA) system in determining antisocial behavior; further studies with larger samples are needed, together with investigation of other components of the GABA pathway.     

Sexual assault perpetrators' tactics: associations with their personal characteristics and aspects of the incident

Past theory and empirical research have consistently associated a number of risk factors with sexual assault perpetration. This study extends past research by considering if the tactics which perpetrators use to obtain sex are associated with these risk factors or with characteristics of the sexual assault. Audio computer-assisted self-interviews were completed with a community sample of young, single men. Few participants reported using physical force as a tactic to obtain sex, thus this article focuses on 457 participants who used verbal coercion ( n = 152) or the victim's impairment (n = 39) to obtain sex or who were nonperpetrators (n = 266). Discriminant function analysis correctly classified 70% of participants. As hypothesized, analysis of covariance indicated that both groups of perpetrators scored higher than nonperpetrators on measures of negative attitudes toward women, positive attitudes about casual sex, personality traits associated with nonclinical levels of psychopathy, antisocial behavior, and alcohol problems. As compared to nonperpetrators describing their worst date, perpetrators knew the woman longer, used more isolating and controlling behaviors, misperceived her sexual intentions for a longer period of time, and engaged in more consensual sexual activities with the woman. Perpetrators who used impairment tactics did not usually consume more alcohol than other participants; however, they consumed much more alcohol during the incident. Although verbal coercion and taking advantage of an impaired victim are sometimes viewed as less serious tactics than the use of force, these findings demonstrate that perpetrators who use these strategies have personality, attitude, and experience profiles that distinguish them from nonperpetrators.     

Differentiation between drug use and environmental contamination when testing for drugs in hair

Personality disorders are associated with criminality and antisocial and borderline personalities as strong predictors of violence. Nevertheless antisocial patients show more instrumental violence, while borderline patients more emotional violence. We surveilled medical records of a personality disorder facility, searching data of aggression and crimes against property among 11 patients with antisocial personality disorder and 19 borderline personality disorder. We found that there are differences regarding engagement in violence and lawbreaking according to the personality disorder: antisocial patients statistically engage more in crimes against property than the borderline patients, and more in this kind of crime than in aggression, whilst borderline patients show a tendency to engage more in episodes of aggression and physical violence than antisocial patients, and less in crimes against property. We conclude that the distinct personality leads to a distinct pattern of crimes and violence: antisocial patients are cold and get more involved in crimes requiring more detailed planning, whilst borderline patients are impulsive and engage in explosive episodes of physical violence. Further studies on the association among personality disorder, behavior pattern and violence type may be useful for both treatment and criminal profiling.     

Variety and frequency scales of antisocial involvement: Which one is better?

Purpose. The aim of this study was to examine whether a scale including frequency scores of antisocial behaviour is a more sensitive and better measure of antisocial involvement than a variety scale. Methods. Data from a representative sample of 1,292 Norwegian students aged 13 and 14 years was used to compare a 17‐item variety scale with two versions of a frequency scale covering the same 17 items. Internal consistency of the scales, stability coefficients (for 1‐year and 2‐year intervals), and associations with conceptually related variables (e.g. aggression, opposition, alcohol consumption) were examined. Results. Results indicated that using a scale including the (raw) frequencies of antisocial acts committed instead of a variety scale would result in reduced internal consistency, lower stability over time, smaller group differences and weaker associations with conceptually related variables. Similarly, in regression analyses the (raw) frequency scale contributed little to the explained variance in conceptually related variables over and beyond that contributed by the variety scale. Conclusions. Although the results for a log‐transformed frequency scale were about as good as for the variety scale, both practical, methodological, and to some extent, conceptual considerations argued against replacing the variety scale with the transformed frequency scale. However, there may be some minor benefits from using an appropriately transformed frequency scale as a supplement to a variety scale, and there are also situations where inclusion of frequency scores in antisocial scales may be essential.     

HOW EFFECTIVE ARE COURT‐AFFILIATED DIVORCING PARENTS EDUCATION PROGRAMS? A META‐ANALYTIC STUDY

In this meta‐analytic study, we looked at all empirical studies that examined the effectiveness of court‐affiliated divorcing parents education programs (DPEs). Overall, we found that DPEs were generally effective. Nineteen studies with a DPE treatment group and no‐treatment control group had an overall significant moderate positive effect (d= .39); those who participated in DPEs were about 50% better off in terms of program outcomes compared to those who did not participate. The studies examined five specific outcomes: co‐parenting conflict, parent‐child relationships, child well‐being, parent well‐being, and relitigation; with most of these specific outcomes we found significant moderate effects ranging from d= .19–.61. However, there were important methodological limitations in this body of research, which are discussed. While more research is needed to confirm the positive potential of DPEs, we probably know enough to justify continuing and even increasing support for this recent social policy innovation.
