Psychometric properties of the Barratt Impulsiveness Scale version 11 among a Portuguese sample of incarcerated juvenile offenders

The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a forensic sample of incarcerated male juvenile offenders (N?=?221). Principal Component Analysis with Promax rotation revealed the expected 6-factor structure, but Confirmatory Factor Analysis of the 6-factor first-order and the 3-factor second-order factorial structures did not present sufficiently good fits. Despite that, the Portuguese adaptation of the BIS-11 demonstrated generally acceptable psychometric properties in terms of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and concurrent validity that justifies its use among the youth forensic population. Statistically significant associations were found with age of crime onset, conduct disorder, crime seriousness, alcohol use and drug use.     

The three dimensions of online child pornography offending

Abstract

The internet has opened up opportunities for non-contact sex offending, such as the viewing of child pornography. This paper proposes a model for the classification of child pornography offenders as an aid for their assessment and treatment, deducted from empirical studies and existing typologies for child pornography offenders. Different subgroups of child pornography offenders may be described according to three dimensions: (1) type of offending, (2) the motivation behind child pornography offending and (3) the situational and social engagement in the offending behaviour. Distinct pathways of child pornography offending can be identified, related to differing criminogenic needs, severity of offending, and appropriate assessment and treatment strategies for the offenders.     

Working with sex offenders: Best practice in enhancing practitioner resilience

Abstract

The systematic and widespread treatment of sex offenders is a comparatively recent innovation in the human services field. Consequently, research considering the impact of such work on providers and organisations is still in its infancy. The first swathe of international research, published throughout the 1990s, identified a range of deleterious effects for treatment providers, ranging from mild anxiety to severe psychological morbidity. More recent findings indicate a considerably more optimistic psychological future. This paper seeks to provide the reader with an overview of the relevant literature, together with its shortcomings, and introduce the Model of Dynamic Adaptation (MDA), a framework through which variables associated with both positive and negative outcomes may be grouped and managed. It is proposed that understanding and managing the MDA can support both individuals and organisations in achieving their goals in good psychological health, through the development and implementation of informed, evidence-based, best practice strategies.     

Children,war and world disorder in the 21st century: a review of the theories and the literature on children's contributions to armed violence

Young populations, and particularly young males, have been attributed a proclivity to aggression and unrest that puts societies at risk. Theories about the dangers of a demographic ‘youth bulge’ inform public and policy debates about the predictors of violent conflict, as evidenced most recently in the World Bank's World Development Report for 2007. This paper assesses the validity and utility of claims linking youth bulges to civil conflicts by reviewing different literatures concerning naturalist ideas of young humans' innate aggression and cognitive incompetence as well as environmentalist ideas of environmental stimuli, processes of socialisation, and the dialectical relationship of structural conditions and human agency. This review finds that the moral panic propagated by youth bulge theorists is too often based on only one form of influence on human development and action, whether an aspect of environment, personal experience, or individual traits. A more cogent analysis must integrate the highly complex and dynamic processes involved in cognition and behaviour and aim to develop theories that take account of the social power, ideational and structural forms, and emotional and cognitive processes that young people experience and draw on in times of war.
