DSM-IV antisocial personality disorder field trial.

The development of the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994) included 12 field trials to assess proposed revisions. This article provides results from the antisocial personality disorder (APD) field trial that was conducted to obtain data of relevance to the proposals for simplification and for the inclusion of more traditional traits of psychopathy. Provided herein are the results from 4 sites that had sampled from populations of particular relevance to the diagnosis of APD (i.e., prison inmates, psychiatric inpatients, outpatients with substance use disorders, and homeless persons). The results indicated that some items from the 3rd revised Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1987) could be deleted without affecting the diagnosis. The field trial provided mixed support for the proposal to include more traditional traits of psychopathy.

Psychiatric comorbidity: prevalence in methadone maintenance treatment.

This study examines prevalence rates for DSM-III-R anxiety and affective disorders in three follow-up samples of opioid addicts who were treated with methadone maintenance. At least one anxiety disorder was diagnosed in 55% of the total sample. Affective disorders were found in 58%. At least one anxiety disorder coexisted with at least one affective disorder in 36% of the sample. The research demonstrates that opiate addiction in this sample is most often associated with other comorbid psychopathology. It suggests a need for thorough assessment for general psychopathology in opioid addicts entering addiction treatment, especially assessment for anxiety and affective disorders. It also suggests the need for treatment that focuses on diagnosed mental disorders in addition to drug counseling for the substance abuse disorder.

Methadone maintenance outcome as a function of detoxification phobia.

OBJECTIVE: Methadone maintenance outcome as a function of detoxification phobia was examined. METHOD: Opiate addicts (N = 271) in a 1983 random sample of methadone maintenance patients from three diverse populations were studied. Subjects from an individually assessed follow-up sample (N = 102) were compared on detoxification phobia. Logistic regression analysis yielded best predictors of the phobia. RESULTS: Phobic patients were more likely to be white, female, and abstinent; to have had fewer detoxification attempts and longer periods on maintenance; to show persistence of the phobia; to meet diagnostic criteria for depressive or anxiety disorders; and to have Addiction Severity Index scores above the 75th percentile for psychological problems. CONCLUSIONS: Detoxification phobia has a complex relationship to methadone maintenance outcome. It is associated with greater abstinence for patients in methadone maintenance treatment. However, for rehabilitated phobic patients it presents a barrier to successful detoxification and a drug-free adjustment that is often associated with other psychopathology but could be ameliorated by targeted assessment and treatment.

Determinants of condom use among intravenous drug users.

OBJECTIVE: To examine the factors associated with condom use among a cohort of sexually active intravenous drug users (IVDU). DESIGN: Data were collected via personal interview at the fourth-month assessment point of a longitudinal study monitoring HIV infection and risk behaviors among IVDU. SETTING: A community-based methadone clinic. PARTICIPANTS: A total of 158 sexually active heterosexual male and female IVDU, including both methadone patients and out-of-treatment individuals with a history of opiate abuse. MAIN OUTCOME MEASURES: We describe a new approach to identify the determinants of condom use. Previous studies have described subjects as either 'condom users' or 'condom non-users', using an individual's overall behavior as the unit of analysis. By analyzing condom use during the most recent sexual encounter, we avoided the problem of interpreting inconsistent condom use. Data were analyzed using forward stepwise logistic regression. RESULTS: Thirty-four per cent of the heterosexual subjects (n = 160) reported using a condom during their last sexual encounter. Being HIV-positive and having either a causal or commercial partner were each associated with increased probability of using a condom (odds ratio, 10.6, 4.4 and 12.1, respectively). No interactions with sex were found. CONCLUSIONS: Our results suggest that knowing that one is HIV-positive is an important determinant of condom use; HIV testing may therefore increase the use of condoms. In addition, interventions to change sexual behaviors may need to focus on the type of sexual partner.

Psychological health-sickness (PHS) as a predictor of outcomes in dynamic and other psychotherapies.

This is the first dedicated review of quantitative studies on Sigmund Freud's proposition that the poorer the psychological health, the more limited are the benefits from treatment. Since observer-rated scales for psychological health-sickness were developed in 1949, many studies have applied them, and the majority show significant prediction of outcomes of psychotherapy, with correlations between .2 and .35. This article reviews (a) the main methods of measurement, (b) the record of predictive success, (c) validity studies, (d) the relation to psychiatric diagnosis, (e) prediction in forms of treatment other than psychotherapy, and (e) theories of why psychological health predicts outcomes of psychotherapy.

A review of the substance use disorders section of the DSM-IV.

The DSM-IV work groups are the first to be given the opportunity to document carefully all stages of deliberations and make decisions based on carefully constructed and data-based criteria. The 5-year process has encouraged the use of detailed literature reviews and allowed members of the working groups to generate data from both MacArthur analyses and field trials to make the most appropriate decisions possible. The Substance Use Disorders Work Group was faced with a potentially infinite number of questions that could be asked. The guidelines presented at the beginning of this article, especially the focus on areas in which data are already available or might potentially be generated from a field trial, allowed our Work Group to focus on a limited number of questions. With rare exceptions, each of these areas was evaluated by the thorough literature reviews that have formed the chapters that make up this section of the Sourcebook. Our goals are relatively straightforward. It is important that clinicians, researchers, administrators, and those who will work the DSM-IV process have full access to the state of the literature that existed in the late 1980s and early 1990s, and the decision-making process that was used to address the issues that affected the DSM-IV. It is hoped that this article will not only help readers to understand both how and why the DSM-IV Substance Use Disorders Work Group made the relevant decisions, but will also encourage active research to answer more fully the potentially important questions raised in these reviews.

High-risk sexual behaviors of intravenous drug users in- and out-of-treatment: implications for the spread of HIV infection.

This paper examines the sexual behaviors of 255 intravenous drug users (IVDUs) to assess the potential for the sexual transmission of HIV and to examine differences in sexual behaviors between in- and out-of-treatment IVDUs. In-treatment subjects (N = 152) were a random sample of clients at a large, publicly funded methadone maintenance program. Out-of-treatment subjects (N = 103) were recruited through a chain referral technique, using the in-treatment subjects. Forty-five percent of the study subjects reported multiple partners and 32% reported exchanging sex for money or drugs in the preceding 6 months. Fifty-three percent reported no use of condoms. After controlling for demographic differences between the in- and out-of-treatment groups, out-of-treatment IVDUs reported significantly more partners than in-treatment IVDUs (4.6 vs 2.3, significant t < 0.01), and more often had exchanged sex for money or drugs (44 vs 26%, relative odds 1.8, p < .05). In- and out-of-treatment subjects did not differ with respect to condom use. We conclude that IVDUs both in- and out-of-treatment continue to be at risk of contracting and spreading HIV infection through sexual behaviors, and that being in drug treatment is associated with a lower incidence of high risk sexual behaviors.

Methadone and edema.

We describe a patient on methadone maintenance who developed distal leg edema after years of treatment. The edema resolved when methadone was discontinued and recurred when it was restarted. This patient is compared to three others reported in the literature who also developed fluid retention shortly after being placed on methadone. We conclude that methadone induced edema can occur not only immediately, but also after years of uncomplicated treatment.

Risk factors for needle sharing among methadone-treated patients.

OBJECTIVE: This paper examines the sociodemographic and psychiatric characteristics of patients taking methadone who continue to share needles. METHOD: Three hundred twenty-three patients were recruited from four methadone programs. Data were collected by using questionnaires and interviews. Psychiatric symptoms were measured with the SCL-90, the Beck Depression Inventory, and the Addiction Severity Index. RESULTS: Twenty percent of these subjects reported sharing needles within the previous 6 months. Those who shared reported greater difficulty in acquiring new needles, more legal difficulties, more severe drug problems, and higher levels of psychiatric symptoms. CONCLUSIONS: These data suggest that patients who continue to share needles are a more disturbed subgroup of the methadone maintenance population. Efforts designed to reduce needle sharing may need to be more sharply focused on patients who are at greatest risk of infection, and these patients may require more intensive psychiatric services.
