Psychopathic criminals commit more crimes, are more prone to recidivism, and more likely to engage in violent crimes and other aggressive behavior than nonpsychopathic criminals. Less is known about forensic patients, both with and without psychopathy, and their aggression. In the current study, patients in a maximum security hospital were examined with respect to their psychopathy and its predictive value on institutional management and dangerousness. In this regard, the Psychopathy Checklist (PCL) and the Psychopathy Checklist - Revised (PCL-R) have proven to be valid and reliable measures of psychopathy. The present study was an attempt to establish predictive validity for a new version: the Psychopathy Checklist Screening Version (PCLSV). As such, this study examined the PCL-SV's relationship to (a) diagnoses of Antisocial Personality Disorder according to DSM-III-R criteria and (b) the Personality Assessment Inventory (PAI) Aggression, Drug Problems, and Antisocial Features scales. The influence of major Axis I disorders on the assessment of psychopathy with the PCLSV was also examined. Participants were 150 male forensic psychiatric patients at Vernon State Hospital who were committed for various reasons: incompetence to stand trial, initial evaluation and treatment after having been found not guilty by reason of insanity, and manifest dangerousness.

The clinical utility of the Intermediate Category Test, a measure of executive functioning in children 9 to 14 years of age, is currently limited by the availability of only a Total Error score for normative interpretation. The Process Scoring System (PSS) was developed to provide a standardized method of assessing specific processing patterns and problem-solving errors. The purpose of this study was to determine the ability of the PSS scores to discriminate between children with and without suspected executive deficits, thereby providing evidence of criterion-related validity.

Using a manufacturing setting that is organized into self-managed teams, the current study identified and measured key leadership behaviors within the teams. Questions that were asked include: are some team leadership behaviors more critical to a team's level of functioning than other behaviors? and do successful self-managed teams rely on formal leadership to a lesser extent than members of less successful teams? These questions were asked in the context of leadership as a process, not an individual.

One hundred twenty-two undergraduate students at the University of North Texas were administered several different optimism scales and also measures of similar constructs such as hope. Results indicated that most measures of optimism show only low to moderate intercorrelations with other measures of the same construct. Additionally, factor analysis confirmed that the measures of optimism actually appear to be assessing multiple factors and not necessarily optimism alone. Implications of the present study include the necessity of individual researchers to be familiar with the specific measure of optimism used in a given study as scores on differing measures of optimism may actually be providing very different information.
