Factors affecting engagement of dual diagnosis patients in outpatient treatment.

This study examined factors associated with engagement in outpatient treatment of patients with dual diagnoses of psychiatric disorder and substance use disorder. The charts of all 57 patients referred to a dual diagnosis treatment program during a six-month period were reviewed, and data on patients' substance use diagnosis, psychiatric diagnosis, sex, ethnicity, and referral source were collected. Patients referred from inpatient treatment were more likely to attend three or more appointments at the dual diagnosis program than those referred from outpatient treatment. Substance of abuse interacted with both referral source and sex in predicting engagement.

A mathematical typology analysis of DSM-III-R personality disorder classification: grade of membership technique.

This study employed grade of membership (GoM) analysis in a clinical setting to determine if the DSM-III-R personality disorder (PD) diagnostic criteria cluster into recognizable disorders resembling the official axis II nosology. The GoM model, based on fuzzy-set theoretic concepts, explicitly examines medical diagnostic systems by quantitatively identifying and characterizing subpatterns of illness within a broad class. A semistructured assessment of 110 outpatients was performed for 12 PDs and their 112 diagnostic criteria. GoM analysis was performed using internal variables of the 112 PD criteria rated as present or absent. Demographic variables, axis I and II diagnosis (structured clinical Interview for DSM [SCID]), and treatment response (Global Adjustment Scale [GAS]) information were used as external validators. Four pure types (PT) provided the most satisfactory solution to the data. PT-I is characterized by marked maladaptive personality pathology, which is manipulative, egocentric, impulsive, and alloplastic. PT-II consists primarily of exaggerated socially anxious and detached traits. PT-III is sociably dependent and autoplastic. PT-IV is essentially asymptomatic. GoM provides a more parsimonious handling of the PD criteria than provided by classifying according to DSM categories. The analysis fails to confirm the natural occurrence of any single specific axis II PD or cluster.

Drug information libraries on the Internet.

UNLABELLED: In the past several years there has been a dramatic proliferation of drug-related sites on the Internet. This article reviews the information found at selected Internet drug information libraries, and comments on its accuracy and implications. Drug-related sites were found by initially performing an Internet search on "psychoactive drugs" and then exploring links among the sites identified. Sites were chosen on the basis of comprehensiveness of information and positive or tolerant attitude toward drug use. While all classes of drugs are discussed at these sites, the primary foci of interest are synthetic and naturally occurring hallucinogens. Many of the biological materials discussed are legal and readily available. Information surveyed at these sites was largely accurate regarding the effects of various substances and biological sources of psychoactive compounds. CONCLUSIONS: Internet drug information libraries contain large amounts of information about a wide variety of drugs, including previously little-known biological sources of hallucinogens. The availability of this information could have significant effects on patterns of drug use.

Theoretical and methodological issues in psychiatric comorbidity.

The occurrence of multiple diagnoses in one patient is a phenomenon of major clinical and theoretical importance. This paper reviews the various factors involved in real and artifactual comorbidity. Important causes of spurious comorbidity are discussed, including invalidity of the individual diagnoses, use of inappropriate diagnostic paradigms, descriptive overlap of diagnostic criteria, ascertainment bias, and diagnostic bias. To illustrate some of the concepts discussed, two examples are presented: the comorbidity of schizophrenia and substance use disorders, and the comorbidity of posttraumatic stress disorder and major depression. The study of comorbidity can advance psychiatry by helping us to clarify our thinking about categories of illness and the boundaries between them, as well as the relationships among these categories.
