OBJECTIVE The study examined behavioral and cognitive factors that may place mentally ill persons at increased risk of infection by the human immunodeficiency virus (HIV). METHODS Sixty-one patients consecutively admitted to a psychiatric inpatient unit of a public general hospital completed questionnaires focused on their knowledge about AIDS and their(More)
OBJECTIVE This study examined factors motivating inpatient aggression in a sample of chronically assaultive state hospital patients. METHODS Inpatients who had committed three or more assaults over a one-year period were identified by using an incident report database. Aggressive episodes were categorized as impulsive, organized, or psychotic by using a(More)
Whereas etiological heterogeneity of the various types of schizophrenia has been repeatedly proposed, relatively few attempts have been made to separate the component diseases. Using a strategy focusing on bimodal distributions within several relevant domains of schizophrenia, we demonstrate that currently available data on schizophrenia patients are(More)
This study was designed to identify the types of neuropsychological deficits that are unique to familial and nonfamilial forms of schizophrenia. Seventy-two patients who met Research Diagnostic Criteria for schizophrenia or schizoaffective disorder, mainly schizophrenic, were divided into two groups on the basis of the presence or absence of a family(More)
The distribution of drug-free plasma homovanillic acid (pHVA) concentrations was studied in a sample of psychotic patients, some of whom were selected for good prognostic features. Baseline pHVA was bimodally distributed, suggesting two different patient populations. The high-pHVA patients showed periods of better functioning and/or fewer symptoms 5 years(More)
Actuarial violence risk assessments, many of which include the construct of psychopathy, have been shown to be superior to clinical judgment in the prediction of long-term risk of community violence and recidivism. While these instruments initially appeared to provide similarly accurate judgments of risk of institutional aggression, recent research has(More)
Although the construct of psychopathy is frequently construed as a unitary syndrome, the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and its revision, the PPI-R (Lilienfeld & Widows, 2005), are composed of 2 scales, termed Fearless Dominance (FD) and Self-Centered Impulsivity (SCI), which appear to reflect orthogonal dimensions. In(More)
Self-efficacy constructs recently have been incorporated into a model of social functioning for schizophrenics. This model proposes that self-efficacy mediates patients' coping efforts. To assess this hypothesis accurately, it is critical to have a scale that measures self-efficacy reliably and validly. Such a scale was developed in this research, which(More)
The ability of psychiatric patients and prisoners to provide informed consent to participate in clinical research has given rise to much debate. Forensic psychiatric patients present a particular concern regarding their competence to consent to research, as they are both patients and prisoners. The primary goal of this research was to evaluate whether, by(More)
