Psychopathic traits in a large community sample: links to violence, alcohol use, and intelligence.

Abstract: Numerous studies conducted with offender or forensic psychiatric samples have revealed that individuals with psychopathic traits are at risk for violence and other externalizing psychopathology. These traits appear to be continuously distributed in these samples, leading investigators to speculate on the presence of such traits in the general population. Nonetheless, few studies of psychopathy have been conducted with large random samples of individuals from the community. The community sample from the MacArthur Violence Risk Assessment Study provides an opportunity to examine the prevalence and structural nature of psychopathic traits, as well as their association with external correlates in an urban community. The community data (N = 514) represent a stratified random sample of persons between the ages of 18 and 40 who were assessed on the Psychopathy Checklist: Screening Version (PCL: SV) and also for violent behavior, alcohol use, and intellectual functioning. Structural equation model analyses revealed that a 4-factor model found in offender and forensic psychiatric samples fit the community data well and was invariant across sex and ethnicity. Also, a superordinate factor comprehensively accounted for the 4 psychopathy first-order factors and significantly predicted the external correlates. The findings offer insight into the dimensional nature of the psychopathy construct.

Practical criteria for screening patients at high risk for diabetic foot ulceration.

Abstract: years), foot deformities (hallux rigidus or hammer toes), male sex, poor diabetes control (glycosylated hemoglobin .9%), 1 or more subjective symptoms of neuropathy, and an elevated vibration perception threshold (.25 V) were significantly associated with foot ulceration. In addition, 59 patients (78%) with ulceration had a rigid deformity directly associated with the site of ulceration. No significant associations were noted between vascular disease, level of formal education, nephropathy, retinopathy, impaired vision, or obesity and foot ulceration on multivariate analysis. Conclusions: Neuropathy, foot deformity, high plantar pressures, and a history of amputation are significantly associated with the presence of foot ulceration. Although vascular and renal disease may result in delayed wound healing and subsequent amputation, they are not significant risk factors for the development of diabetic foot ulceration.

A critical review of the role of neonatal hearing screening in the detection of congenital hearing impairment

Abstract: Background This review was commissioned because of the increasing doubt about the ability of existing screening programmes (mainly the health visitor distraction test (HVDT) at 7-8 months) to identify children with congenital hearing impairment, and technological advances which have made neonatal hearing screening an alternative option. Objectives To review the available literature on the screening of permanent childhood hearing impairment. To provide commissioners and providers of health care with information about how to deliver a more uniform service, better outcomes, and more cost-effective screening. To identify areas for further research and service development. How the research was conducted The research involved a review of the available published and unpublished literature, and a comprehensive survey of current pre-school hearing screening provision in the UK coupled with a health economics study of hearing screening costs. The research also included a number of focus groups and visits to key centres in the UK and North America. Research findings EPIDEMIOLOGY OF PERMANENT CHILDHOOD HEARING IMPAIRMENT: There are approximately 840 children a year born in the UK with significant permanent hearing impairment likely to affect their own and their family's quality of life. Present services will miss about 400 of these children by 1 1/2 years of age, and about 200 of these children by 3 1/2 years of age. Such late identification of hearing impairment greatly reduces the responsiveness of the services for individual children. Evidence for improved outcomes with earlier identification Hearing-impaired children identified late are at risk of substantial delay in their acquisition of language and communication skills, with consequent longer-term risk to education achievement, mental health and quality of life. Theoretical arguments on neural development support the limited evidence here for the increased benefit for child and family associated with very early identification. In general, parents and professionals want very early identification, which, if implemented properly, does not cause undue anxiety. Current uk practice The survey of current practice indicated a major problem with poor information systems. This problem was further highlighted as a major concern by the multi-disciplinary focus groups. Practice varies. There are two District-wide programmes in which all newborn babies are neonatally screened, a large number of ad hoc programmes for neonatal screening of 'at-risk' babies, a variety of early surveillance programmes, and widespread use of the HVDT. Intervention and habilitation for the majority of those screened neonatally is routinely undertaken within 6 months of birth. For those screened only by the health visitor, identification was on average at about 26 months of age with intervention at about 32 months on average. (ABSTRACT TRUNCATED)

Systematic review of screening instruments for adults at risk of PTSD

Abstract: The development of effective methods of screening for posttraumatic stress disorder (PTSD) is important in the context of mass trauma, the geographical dispersion of victims, and the restricted availability of specialists in psychological trauma. The review focused on published English-language screening instruments for civilian PTSD consisting of 30 items or fewer and validated against structured clinical interviews. Thirteen instruments were identified meeting these criteria, all consisting of symptoms of traumatic stress. The review concluded that the performance of some currently available instruments is near to their maximal potential effectiveness, and that instruments with fewer items, simpler response scales, and simpler scoring methods perform as well as if not better than longer and more complex measures.
