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.

On the Malleability of Self-Control: Theoretical and Policy Implications Regarding a General Theory of Crime
Authors: Alex R. Piquero; Wesley G. Jennings; David P. Farrington

Gottfredson and Hirschi's general theory of crime has generated significant controversy and research, such that there now exists a large knowledge base regarding the importance of self-control in regulating antisocial behavior over the life-course. Reviews of this literature indicate that self-control is an important correlate of antisocial activity. Some research has evaluated programmatic efforts designed to examine the extent to which self-control is malleable, but little empirical research on this issue has been carried out within criminology, largely because the theorists have not paid much attention to policy proscriptions. This study evaluates the extant research on the effectiveness of programs designed to improve self-control up to age 10 among children and adolescents, and assesses the effects of these programs on self-control and delinquency/crime. Meta-analytic results indicate that (1) self-control programs improve a child/adolescent's self-control, (2) these interventions also reduce delinquency, and (3) the positive effects generally hold across a number of different moderator variables and groupings as well as by outcome source (parent-, teacher-, direct observer-, self-, and clinical report). Theoretical and policy implications are also discussed.

Where the Margins Meet: A Demographic Assessment of Transgender Inmates in Men's Prisons
Authors: Lori Sexton; Valerie Jenness; Jennifer Macy Sumner

Drawing on official data and original interview data on 315 transgender inmates in California prisons for men, this research provides the first empirical portrayal of a prison population in California that is unique by virtue of being both transgender and incarcerated. Situated at the nexus of intersecting marginalities, transgender inmates fare far worse on standard demographic and health measures than their non-transgender counterparts in the US population, the California population, the US prison population, and the California prison population. With the possible exceptions of partnership status and educational attainment, these factors combine to reveal that transgender inmates are marginalized in heretofore undocumented ways. At a time in which an evidence-based approach to corrections is increasingly embraced by corrections officials in the US, this article provides the first systematic profile of transgender prisoners. It reveals they can be regarded as a special population that, from a policy point of view, raises what Minow calls “the dilemma of difference”.

Racial and Ethnic Heterogeneity, Economic Disadvantage, and Gangs: A Macro-Level Study of Gang Membership in Urban America Pages 867 - 892
Authors: David C. Pyrooz; Andrew M. Fox; Scott H. Decker

There is a lack of macro-level gang research. The present study addresses this shortcoming by providing a theoretically informed analysis of gang membership in large US cities. More specifically, our goal is to determine whether racial and ethnic heterogeneity conditions the relationship between economic disadvantage and gang membership. Three separate sources of data are used in this study: U.S. Census 2000, Law Enforcement Management and Administrative Services 2000, and National Youth Gang Survey 2002-2006. A series of weighted least-squares regression models are estimated, finding that both economic disadvantage and racial and ethnic heterogeneity exhibit independent and additive effects on gang membership. In addition, the results show that racial and ethnic heterogeneity has a conditioning relationship with economic disadvantage. Furthermore, our expanded operationalization of the Blau heterogeneity measure indicates that prior research may have underestimated the effects of heterogeneity. The authors discuss these findings in the context of existing gang research and offer directions for future research.

Community In-Reach Through Jail Reentry: Findings from a Quasi-Experimental Design
Authors: Holly Ventura Miller; J. Mitchell Miller

Offenders face a number of significant challenges upon reentry into the community, including securing employment, locating housing, and accessing adequate substance abuse and mental health treatment. These and related issues, if neglected, only bolster rising recidivism rates which have prompted renewed interest in rehabilitation initiatives such as inmate reentry. Many jurisdictions have implemented programs designed to improve offenders' success after prison, but jail reentry programs are far less common. This study examined the effectiveness of one such program, the Auglaize County (OH) Transition (ACT) Program. Using a quasiexperimental design, recidivism was measured a year after release to determine if participation in the ACT Program was predictive of successful reentry. Findings suggest that program participation is strongly related to outcome success as was criminal history. Implications for correctional policy and suggestions for additional jail reentry research are considered.
