The use of psychological interventions for adult male sex offenders with a learning disability: a systematic review†

ABSTRACT

There is a drive to attend to the specific treatment needs of sexual offenders with a learning disability (LD) and increasing recognition of treatment limitations in this group. Cognitive behavioural therapy (CBT)-based sex offender treatment programmes (SOTPs) are being increasingly adapted for the LD population. This review systematically considers the evidence base for LD adapted CBT-based SOTPs. Ten studies together comprising 358 participants were reviewed. LD adapted SOTPs were conducted in prisons, secure settings and in the community. Within-treatment findings generally indicated positive cognitive shift, improvements in victim empathy and increased sexual knowledge on psychometric measures. Whilst findings are encouraging, many of the studies have methodological limitations. In particular, all studies used pre-test post-test study designs lacking control groups therefore restricting the evaluation of treatment outcomes. The LD sex offender literature remains underdeveloped and there is a strong case for further research to establish a valid evidence base for treatment.     

The Public Purpose of Political Economy

ABSTRACT

For too long the discipline of political science has ceded research on the dynamics of the national political economy to the field of economics. In this article, we explore the cost of this cession in the context of the public purpose. Following John Kenneth Galbraith, we define the public purpose in terms of its independence from the market economy and the planning system. Political scientists, and especially political theorists, are uniquely qualified to theorize power relations relative to a host of challenges that have emerged in today’s rapidly transforming national economies. Galbraith’s critique of mainstream economics, coupled with his understanding of power as an inescapable and perpetual dialectical process, provide guidance for theorizations that should attend to rather than deny the contested domain of the public interest and collective good.     

Firing Back at the Backfire Effect: The Influence of Mortality Salience and Nullification Beliefs on Reactions to Inadmissible Evidence

Two studies were conducted to explore psychological factors that contribute to the influence of inadmissible evidence (i.e., the backfire effect) on jurors' verdicts. On the basis of hypotheses derived from terror management theory, we predicted that reminders of mortality, in contrast to an aversive control topic, should lead participants to be less punitive when confronted with inadmissible (as opposed to admissible) evidence, when participants were either situationally induced or dispositionally prone to follow their personal sense of justice. In Study 1, control participants who scored high on a measure of nullification beliefs, and thus were prone to relying on their own sense of justice rather than the law, exhibited the backfire effect. However, reminding participants of their mortality reduced the damaging influence of inadmissible evidence. Study 2 extended these findings by showing parallel effects with a manipulation of nullification proneness via judicial instructions. The implications of these factors on the judicial process are discussed.     

The Course and Psychosocial Correlates of Personality Disorder Symptoms in Adolescence: Erikson's Developmental Theory Revisited

Personality disorder symptoms were investigated in a community sample of young people (n = 714) to assess their relationship over time with well-being during adolescence and the emergence of intimacy in early adulthood. Drawing on Erikson's theory of psychosocial development, changes in adolescent well-being were conceptualized as indirect indicators of identity consolidation. Cluster B personality disorder symptoms (borderline, histrionic, and narcissistic symptoms) were conceptualized to represent identity diffusion—i.e. maladaptive personality traits that usually resolve during the identity crisis of adolescence. Latent growth models were used in 2 age cohorts to assess (1) interrelationships between Cluster B symptoms, well-being, and intimacy at mean ages 13.8 and 18.6 years; and (2) associations between their developmental trajectories over the next 6 years. As expected, higher personality disorder symptoms were associated with lower well-being during adolescence, and declines in personality disorder symptoms over time were associated with corresponding gains in well-being. Consistent with Erikson's developmental theory, there was an inverse relationship between Cluster B symptoms and intimacy that increased in strength as young people entered adulthood. As an indicator of successful identity consolidation, well-being was significantly associated with intimacy in female adolescents and young adults.     

The Correlates of Life Quality in U.S. Metropolitan Areas

This study analyzes the correlates of life quality differencesin 243 U.S. metropolitan areas. Using an overall index of lifequality developed by Ben-Chieh Liu, it tests the empirical utilityof three competing explanations—racial dualism, economicdevelopment, and political culture. The results show that allthree exert substantial effects on the quality of life regardlessof metropolitan size. Overall the best predictor of life qualitydifferences is the percentage of adults who have received atleast a high school education. In addition, cultural differencesexert significant effects on the quality of metropolitan lifeindependent of racial and developmental differences. These culturaleffects are interpreted within two theoretically seminal theories:Elazar's theory of political culture and Gastil's theory ofcultural regions.     

Local Government Failure in Australia? An Empirical Analysis of New South Wales

The complexities of contemporary local governance in Australia and other advanced democracies provide social scientists with significant theoretical and empirical challenges. Drawing on recent developments, including public choice theory, economists have sought to develop taxonomic systems of government failure specifically tailored to local government circumstances. This paper seeks to extend the Dollery and Wallis (2001b) taxonomy of local government failure by invoking Olson's (1965) concept of political entrepreneurship. The paper then attempts to determine the empirical validity of the augmented taxonomy by examining it in the context of NSW local government.     

Some observations on the link between learning disabilities and juvenile delinquency

In order to test the hypothesis that learning disabilities are related to juvenile delinquency, a sample of 1,005 public school and 687 adjudicated juvenile delinquent youths (ages 12 to 17) reported about delinquent behaviors in which they had engaged. The youths' educational records were screened, and, if the presence of learning disabilities could not be discounted, the children were given a series of tests. Every child was classified as either learning disabled or not. The results indicated that proportionately more adjudicated delinquent children than public school children were learning disabled. Self-report data, however, showed no differences in delinquent behaviors engaged in by learning-disabled and non-learning-disabled children, within either the adjudicated or public school samples. Public school children who have learning disabilities reported that they were picked up by the police at about the same rate as non-learning-disabled children, and engaged in about the same delinquent behaviors. Charges for which learning-disabled and non-learning-disabled adjudicated delinquents were convicted followed the same general patterns. In light of these findings, it was proposed that the greater proportion of learning-disabled youth among adjudicated juvenile delinquents may be accounted for by differences in the way such children are treated within the juvenile justice system, rather than by differences in their delinquent behaviors.
