Re-examining the long-term effects of experiencing parental death in childhood on adult psychopathology.

This study examined whether the experience of the death of a parent in childhood increases risk for adult psychopathology. Participants consisted of 3481 men and women gathered through the Baltimore Epidemiologic Catchment Area study in 1981 and followed through 1994-1995. The Diagnostic Interview Survey was administered by trained interviewers and was used to assess DSM-III disorders including major depression, panic, and anxiety disorders.

The long-term outcomes of drug use by methadone maintenance patients.

The aim of the study is to predict long-term outcomes of methadone maintenance (MM), other than continued heroin use, on the basis of drug use occurring early in MM treatment. In previous research, the weak association of initial drug use during MM with measures of rehabilitation status may be due to the use of measures that do not differentiate trends in different types of drug use. In the present study, 222 patients who completed 6 months of MM were assessed at program intake, evaluated for opiates and cocaine in the first 6 months of treatment, and given a follow-up assessment 2 years after treatment entry.

Status hearings in drug court: when more is less and less is more.

We examined the effects of increasing the number of times misdemeanor drug court clients appeared before a judge for judicial status hearings. Our previous findings showed no main effect of increased hearings during the first 14 weeks of the program. The present study examined participants' discharge status in the program, and also explored potential interactions between client characteristics and the frequency of judicial status hearings on outcomes.

The prediction of violent and nonviolent criminal behavior in a methadone maintenance population.

The utility of traits associated with Antisocial Personality Disorder in making risk assessments of violent and nonviolent crimes was examined in 254 subjects sampled from a methadone maintenance population. A factor analysis of a number of baseline measures resulted in five factors measuring hostility, insecure attachment, impaired reality testing, antisocial personality, and empathy. These factors were used in logistic regression analysis to predict charges for violent and nonviolent crimes over a 2-year period.

Staff beliefs about drug abuse clinical trials.

Staff from 10 community-based addiction treatment organizations in the National Drug Abuse Clinical Trials Network participated in an educational session about addiction research practices and human subject protections. This 1.5-hour presentation addressed "informed consent," "confidentiality of research information," "inclusion and exclusion criteria," "random assignment," "patient protections," and "patient payments.
