Structural, item, and test generalizability of the psychopathology checklist - revised to offenders with intellectual disabilities

The Psychopathy Checklist–Revised (PCL-R) is the most widely used measure of psychopathy in forensic clinical practice, but the generalizability of the measure to offenders with intellectual disabilities (ID) has not been clearly established. This study examined the structural equivalence and scalar equivalence of the PCL-R in a sample of 185 male offenders with ID in forensic mental health settings, as compared with a sample of 1,212 male prisoners without ID. Three models of the PCL-R’s factor structure were evaluated with confirmatory factor analysis. The 3-factor hierarchical model of psychopathy was found to be a good fit to the ID PCL-R data, whereas neither the 4-factor model nor the traditional 2-factor model fitted. There were no cross-group differences in the factor structure, providing evidence of structural equivalence. However, item response theory analyses indicated metric differences in the ratings of psychopathy symptoms between the ID group and the comparison prisoner group. This finding has potential implications for the interpretation of PCL-R scores obtained with people with ID in forensic psychiatric settings

Extreme managers, extreme workplaces: capitalism, organizations and corporate psychopaths

This paper reports on in-depth, qualitative research carried out in England in 2013 among five organizational directors and two senior managers who had worked with other senior directors or managers who were Corporate Psychopaths, as measured by a management psychopathy measure. The Corporate Psychopaths reported on in this research displayed remarkable consistency in their approach to management to the extent that they could be called “text book examples” of managerial psychopathy. They were seen as being organizational stars and as deserving of performance awards by those above them, while the Corporate Psychopaths simultaneously subjected those below them to extreme forms of behavior, including bullying, intimidation and coercion and also engaged in extreme forms of mismanagement; such as very poor levels of personnel management, directionless leadership, miss-management of resources and outright fraud

Inpatient coronary angiography and revascularisation following non-ST-elevation acute coronary syndrome in patients with renal impairment: a cohort study using the Myocardial Ischaemia National Audit Project.

BACKGROUND: International guidelines support an early invasive management strategy (including early coronary angiography and revascularisation) for non-ST-elevation acute coronary syndrome (NSTE-ACS) in patients with renal impairment. However, evidence from outside the UK suggests that this approach is underutilised. We aimed to describe practice within the NHS, and to determine whether the severity of renal dysfunction influenced the provision of angiography and modified the association between early revascularisation and survival. METHODS: We performed a cohort study, using multivariable logistic regression and propensity score analyses, of data from the Myocardial Ischaemia National Audit Project for patients presenting with NSTE-ACS to English or Welsh hospitals between 2008 and 2010. FINDINGS: Of 35 881 patients diagnosed with NSTE-ACS, eGFR of 90 ml/minute/1.73 m(2), patients with an eGFR between 45-59 ml/minute/1.73 m(2) were 33% less likely to undergo angiography (adjusted OR 0.67, 95% CI 0.55-0.81); those with an eGFR<30/minute/1.73 m(2) had a 64% reduction in odds of undergoing angiography (adjusted OR 0.36, 95%CI 0.29-0.43). Of 16 646 patients who had inpatient coronary angiography, 58.5% underwent inpatient revascularisation. After adjusting for co-variables, inpatient revascularisation was associated with approximately a 30% reduction in death within 1 year compared with those managed medically after coronary angiography (adjusted OR 0.66, 95%CI 0.57-0.77), with no evidence of modification by renal function (p(interaction) = 0.744). INTERPRETATION: Early revascularisation may offer a similar survival benefit in patients with and without renal dysfunction, yet renal impairment is an important determinant of the provision of coronary angiography following NSTE-ACS. A randomised controlled trial is needed to evaluate the efficacy of an early invasive approach in patients with severe renal dysfunction to ensure that all patients who may benefit are offered this treatment option

The equity-efficiency trade-off in environmental policy: evidence from stated preferences

The design of environmental policy raises several equity issues, in particular the distribution of benefits and costs. At the same time, it has often been argued that there is a trade-off in environmental policy between equity and efficiency, which brings these issues firmly to the attention of environmental economics. In this paper we use a simple choice experiment to elicit individual preferences over equity-efficiency trade-offs in the context of two environmental problems, local air pollution and global climate change. We find that equity matters to people as much as efficiency does in the design and delivery of environmental policy
