The stability of psychopathic personality disturbance (PPD) has important theoretical implications for developmental criminology and population heterogeneity perspective assertions that psychopathy is a key measure of criminal propensity. Data from the Pathways to Desistance Study ( n = 1,354) were used to examine short-, moderate-, and long-term reliable change in symptoms of PPD measured via the Youth Psychopathic Traits Inventory (YPI). Youth scoring highest on the YPI at the baseline assessment were most likely to experience reliable decreases in test scores. Binomial regression analyses showed that a reliable decrease in YPI test score was associated with decreased odds of endorsing additional offenses. Findings contrasted the adolescent “fledgling” psychopathy perspective and indicated that individuals scoring high on the YPI are the group most likely to experience reliable decreases in test scores, especially over a longer follow-up period.

Abstract There are ∼7000 rare diseases affecting 30 000 000 individuals in the U.S.A. 95% of these rare diseases do not have a single Food and Drug Administration-approved therapy. Relatively, limited progress has been made to develop new or repurpose existing therapies for these disorders, in part because traditional funding models are not as effective when applied to rare diseases. Due to the suboptimal research infrastructure and treatment options for Castleman disease, the Castleman Disease Collaborative Network (CDCN), founded in 2012, spearheaded a novel strategy for advancing biomedical research, the ‘Collaborative Network Approach’. At its heart, the Collaborative Network Approach leverages and integrates the entire community of stakeholders — patients, physicians and researchers — to identify and prioritize high-impact research questions. It then recruits the most qualified researchers to conduct these studies. In parallel, patients are empowered to fight back by supporting research through fundraising and providing their biospecimens and clinical data. This approach democratizes research, allowing the entire community to identify the most clinically relevant and pressing questions; any idea can be translated into a study rather than limiting research to the ideas proposed by researchers in grant applications. Preliminary results from the CDCN and other organizations that have followed its Collaborative Network Approach suggest that this model is generalizable across rare diseases.

Das Psychopathic Personality Inventory Revised (PPI-R) wurde bisher anhand der Daten gesunder, nicht straffälliger Probanden validiert. Die vorliegende Untersuchung überprüft die Validität des PPI-R für Straftäterstichproben. Die PPI-R Werte von 152 männlichen Patienten des Maßregelvollzugs, 65 Strafgefangenen und 214 männlichen Studenten wurden verglichen. Es wurden Reliabilitätskoeffizienten sowie Korrelationen mit der PCL-R berechnet. Es ergaben sich gute Reliabilitätskoeffizienten in der forensischen und der Strafgefangenen-Stichprobe. Die forensischen Patienten unterschieden sich signifikant von der gesunden Gruppe im Gesamtwert des PPI-R. Der PPI-R Gesamtwert und die PCL-R sowie deren Faktoren korrelierten signifikant. Obwohl die Gütekriterien des PPI-R auch in Straftätergruppen repliziert werden konnten, legen die Ergebnisse die Verwendung spezifischer Referenzwerte nahe. Einschränkungen des Einsatzes im Rahmen von prognostischen Aussagen sind zu beachten.

Abstract University students were screened using items from the Psychopathic Personality Inventory and divided into high (n = 13) and low (n = 11) Psychopathic Personality Trait (PPT) groups. The P300 component of the event-related potential (ERP) was recorded as each group completed a two-block autobiographical oddball task, responding honestly during the first (Phone) block, in which oddball items were participants' home phone numbers, and then feigning amnesia in response to approximately 50% of items in the second (Birthday) block in which oddball items were participants' birthdates. Bootstrapping of peak-to-peak amplitudes correctly identified 100% of low PPT and 92% of high PPT participants as having intact recognition. Both groups demonstrated malingering-related P300 amplitude reduction. For the first time, P300 amplitude and topography differences were observed between honest and deceptive responses to Birthday items. No main between-group P300 effects resulted. Post-hoc analysis revealed between-group differences in a frontally located post-P300 component. Honest responses were associated with late frontal amplitudes larger than deceptive responses at frontal sites in the low PPT group only.
