Kinds of Screening Device Selected AbstractsExamining psychopathic tendencies in adolescence from the perspective of personality theoryAGGRESSIVE BEHAVIOR, Issue 5 2009Naomi Sadeh Abstract This study sought to clarify the personality correlates of psychopathic tendencies in adolescents using the Antisocial Process Screening Device [APSD; Frick and Hare, 2001] and a youth adapted version of the Multidimensional Personality Questionnaire [Patrick et al., 2009, unpublished]. A combination of self- and parent-reports on the APSD (n=229) revealed that the three-facet model of psychopathic tendencies in youth was characterized by a similar constellation of personality traits as the psychopathic construct in adulthood [e.g., Hall, Benning and Patrick, 2004]. Specifically, low anxiety and trait aggression characterized the APSD Callous/Unemotional dimension, social dominance and trait aggression characterized the APSD Narcissism dimension, and disinhibition and low harm avoidance characterized the APSD Impulsivity dimension. The results add credence to the hypothesis that personality relationships to psychopathic tendencies emerge from an early age [Lynam, 2002] and dimensions of psychopathy in youth are associated with distinct personality profiles.

[source] A preliminary examination of the intergenerational continuity of maternal psychopathic featuresAGGRESSIVE BEHAVIOR, Issue 1 2007Bryan R. Loney Abstract The study provided a preliminary test of the intergenerational continuity of maternal psychopathic features in a non-referred elementary aged sample of children. Consistent with dominant etiological models and recent behavioral genetics research, a direct association was expected between maternal and child affective features of psychopathy (i.e., callous,unemotional or CU traits). Potential mediators representative of alternative transmission mechanisms were assessed including parenting dysfunction, parental hostility/interpersonal insensitivity, and child impulsivity. Behavioral features of psychopathy were also assessed and were predicted to bear weaker and more indirect parent,child associations. A mixed sex sample of 83 children accompanied by a biological mother were administered a multi-informant rating-scale battery including separate parent (i.e., Levenson Self-Report Psychopathy Scale) and child (i.e., Antisocial Process Screening Device) measures of psychopathy. Consistent with prediction, a significant association was documented between maternal and child CU traits (r=.22). Additionally, a slightly weaker association and statistical trend (r=.21) was observed in the relation between maternal and child interpersonal features of the psychopathy construct. Contrary to prediction, all documented associations were fully mediated by parental hostility and parenting dysfunction. Given the preliminary nature of study findings, implications for developmental modeling and future intergenerational continuity research are discussed. Aggr.

Murrie Ph.D. This study examined the relations between psychopathy scores and violent behavior in 113 incarcerated adolescents. We compared the results of four different instruments designed to assess psychopathy features among juveniles,the Psychopathy Checklist: Youth Version (PCL:YV), two versions of the Antisocial Processes Screening Device (APSD), and a Psychopathy Content scale on the Millon Adolescent Clinical Inventory (MACI). We found that PCLY:YV scores were significantly correlated with violent offense history, unadjudicated violence, and institutional violence, as well as measures of the severity and instrumentality of prior violence. Receiver operating characteristic analyses generated statistically significant effect sizes (AUC values) ranging from 0.64 to 0.79. The three other measures generated statistically significant correlations with one or more of the violence criteria, although correlations and effect sizes tended to be smaller in magnitude. Our results offer some support for the validity of these measures of psychopathic features, and the value of the PCL:YV in particular, with respect to short-term measures of violence outcome among juvenile offenders.

[source] The validity of the Antisocial Process Screening Device as a self-report measure of psychopathy in adolescent offenders,BEHAVIORAL SCIENCES & THE LAW, Issue 6 2003Zina Lee Ph.D. There is a growing interest in the assessment of adolescent psychopathy to enable early treatment and intervention. Recently, a self-report measure has been developed to assess psychopathic traits in adolescents. The Antisocial Process Screening Device (APSD), a self-report measure of psychopathic traits, and the Psychopathy Checklist: Youth Version (PCL:YV), a clinical rating scale, were administered to a sample of 100 incarcerated male adolescent offenders to assess the concurrent validity of the APSD. Results indicated that the APSD had limited concurrent validity with respect to the PCL:YV and that there appears to be a method effect in the measurement of psychopathy. Thus, it appears the APSD did not assess psychopathy in a manner parallel to that of the PCL:YV. Copyright © 2003 John Wiley & Sons, Ltd. [source] A Randomized, Double-blind, Sham-controlled Trial Comparing Two Screening Devices for Radiation ContaminationACADEMIC EMERGENCY MEDICINE, Issue 9 2010Philip Salen MD Abstract Objectives:, This exploratory study compared the screening ability of a newly introduced radiation detection portal with a traditional Geiger counter for detection of radiation contamination in the setting of a mass casualty training exercise. Methods:, Following a pretrial evaluation of interobserver reliability for Geiger counter use, 30 volunteers were randomly assigned to don gowns containing three disks, each of which was either a sham resembling the radioactive samples or an actual cesium-137 sample; each subject participated a minimum of four times with different gowns each time. Each subject underwent standard radioactivity screening with the Geiger counter and the portal. Results:, Interobserver reliability was excellent between the two Geiger counter screeners in the pretrial exercise, correctly identifying 101 of 102 sham and radioactive samples (, = 0.98; 95% confidence interval [CI] = 0.94 to 1.00). For radioactively labeled subjects across all bodily locations, the portal (43/61, or 70.5%; 95% CI = 58.1% to 80.5%) was less sensitive than the Geiger counter screening (61/61, or 100%; 95% CI = 92.9% to 100%), which resulted in a portal false-negative rate of 29.5%. For radiation detection in the posterior thorax, the portal radiation screening (4/19, or 21.1%; 95% CI = 8% to 43.9%) was less accurate than the Geiger counter (19/19, or 100%; 95% CI 80.2% to 100%). In contrast, there were no major differences between the portal and the Geiger counter for radiation detection at the left shoulder, right shoulder, or sham (nonradiation) detection. There were no false-positive detections of the sham-labeled subjects for either device, yielding a specificity of 100% for both screening modalities. Conclusions:, Geiger counter screening was more sensitive than, and equally specific to, radiation detection portal screening in detecting radioactively labeled subjects during a radiation mass casualty drill.

High risks buy complete insurance, whereas low risks buy partial insurance,and this result holds for the Nash behavior as well as for the Wilson foresight. In this article, we analyze the strength of screening based on limitations to the period of coverage of the contract. We show that in this case (1) the Nash equilibrium may entail low risks not purchasing any insurance at all, and (2) under the Wilson foresight, a pooling equilibrium may exist. [source] Screening by the Company You Keep: Joint Liability Lending and the Peer Selection EffectTHE ECONOMIC JOURNAL, Issue 465 2000Maitreesh Ghatak We look at an economic environment where borrowers have some information about the nature of each other's projects that lenders do not. We show that joint-liability lending contracts, similar to those used by credit cooperatives and group-lending schemes, will induce endogenous peer selection in the formation of groups in a way that the instrument of joint liability can be used as a screening device to exploit this local information. This can improve welfare and repayment rates if standard screening instruments such as collateral are unavailable.

Magnetic resonance imaging demonstrated a large epidural thoracic arachnoid cyst. This case highlights the need to consider that the management of patients with giant congenital melanocytic naevus is variable depending on the age of the patient, the location of lesions and the presence of complications such as neurocutaneous melanosis. The value of magnetic resonance scanning as a screening device is discussed. [source] Impact of skin tone on the performance of a transcutaneous jaundice meterACTA PAEDIATRICA, Issue 12 2009Stephen Wainer Abstract Aim:, To evaluate the performance of the Konica Minolta/Air-Shields® JM-103 jaundice meter on the basis of infant skin tone during the early neonatal period. Methods:, Infants were prospectively categorized into light, medium and dark skin tone groups relative to two reference colours. Transcutaneous bilirubin readings were taken at predetermined intervals through the early neonatal period on a convenience sample of 938 healthy infants ,37 weeks gestation. Serum bilirubin measurements were drawn routinely with metabolic studies and repeated in the presence of an elevated transcutaneous reading or clinically significant jaundice. Results:, Multivariate linear regression analysis showed a significant impact on serum and transcutaneous bilirubin agreement by skin tone. Highest precision and lowest bias were observed for medium skin toned infants. Greater disagreement between serum and transcutaneous measurements was noted at serum bilirubin concentrations >200 ,mol/L. Insufficient numbers of dark skin toned infants were enroled to evaluate fully the performance of the jaundice meter for this group. Conclusion:, The JM-103 jaundice meter displayed good correlation with serum bilirubin concentrations in light and medium skin tone infants, although it showed a tendency to under-read in the lighter skin tone group and to over-read in the darker skin tone group. The device shows excellent performance characteristics for use as a screening device. [source] Practitioner Review: Approaches to assessment and treatment of children with DCD: an evaluative reviewTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 8 2005Peter H. Wilson Background:, Movement clumsiness (or Developmental Coordination Disorder , DCD) has gained increasing recognition as a significant condition of childhood. However, some uncertainty still exists about diagnosis. Accordingly, approaches to assessment and treatment are varied, each drawing on distinct theoretical assumptions about the aetiology of the condition and its developmental course. Method:, This review evaluates the current status of different approaches to motor assessment and treatment for children with DCD. These approaches are divided according to their broad conceptual origin (or explanatory framework): Normative Functional Skill Approach, General Abilities Approach, Neurodevelopmental Theory, Dynamical Systems Theory, and the Cognitive Neuroscientific Approach. Conclusions:, Each conceptual framework is shown to support assessment and treatment methods with varying degrees of conceptual and psychometric integrity. The normative functional skill approach supports the major screening devices for DCD and cognitive (or top-down) approaches to intervention. The general abilities approach and traditional neurodevelopmental theory are not well supported by recent research. The dynamical systems approach supports promising trends in biomechanical or kinematic analysis of movement, ecological task analysis, and task-specific intervention. Finally, and more recently, the cognitive neuroscientific approach has generated some examples of process-oriented assessment and treatment based on validated (brain,behaviour) models of motor control and learning. A multi-level approach to movement assessment and treatment is recommended for DCD, providing a more complete representation of motor development at different levels of function , behavioural, neurocognitive, and emotional.
