Effects of psychiatric care for dual diagnosis patients treated in a drug dependence clinic.

This study examines outcome of treatment for psychoactive substance dependence in a clinic which made psychiatric care readily available. Veterans entering outpatient treatment for substance dependence (n = 222) received psychiatric evaluation for additional Axis I disorders using DSM-III-R criteria. Patients provided urine toxicology specimens at least weekly. Outcome (urinalysis results and treatment retention) was compared for patients with dual diagnosis (n = 103, 46.4%) and with substance only diagnosis (n = 119, 53.6%). Psychotropic medications were prescribed for 80.4% of the dual diagnosis subjects. In the first 6 months of treatment, dual diagnosis subjects compared to substance only diagnosis subjects gave a significantly greater percentage of urines positive for cocaine and opioids. In the second 6 months, dual diagnosis subjects who remained (n = 72, 70.0%) significantly reduced from the first 6 months their percentage of cocaine and opioid positives and did not differ in percent positives from substance only diagnosis subjects who continued past 6 months (n = 70, 58.8%). Treatment retention of dual diagnosis subjects (median months = 14.3) exceeded that of substance only diagnosis subjects (8.9; Lee-Desu Statistic = 9.02, p < .003). Dual diagnosis patients may initially perform more poorly than substance only diagnosis patients in substance dependence treatment. However, in the presence of psychiatric care, they eventually exhibit comparable success.

Reporting of HIV risk behaviors by injection drug using heterosexual couples in methadone maintenance.

This study sought to identify differences within injection drug using (IDU) couples in reporting of sexual and needle risk behavior. Subjects were thirty-nine heterosexual couples entering methadone maintenance. In 33.3% of couples, one member reported sharing needles while the other member reported no sharing. In 12.9% of couples, one member reported sharing injection equipment, while the other member reported no sharing. Agreement was 77.4% between members of monogamous couples regarding frequency of condom use, 80.7% regarding vaginal intercourse with condoms, and 25.8% regarding vaginal intercourse without condoms. Within couples, a number of differences between members of the couple in injection equipment sharing were noted, suggesting that individuals who attempt to protect themselves by not sharing injection equipment may be placed at risk by their sexual partners. Further clinical and research efforts should be directed toward reducing barriers to behavior that would protect both partners. Implications for self-report measurement of HIV risk behavior and for preventive interventions are discussed.

Longitudinal changes in injection behaviors in a cohort of injection drug users.

To determine how the injecting behaviors of injection drug users (IDUs) change over time in the context of the epidemic of acquired immunodeficiency syndrome (AIDS) and what factors may be associated with such changes, a cohort of IDUs (n = 313) initially in treatment provided structured interviews regarding drug injecting behaviors. Repeat interviews in 18 months assessed behavior change in subjects who could be contacted for follow-up (n = 220, 70.3%). The study occurred in a state where sterile syringes can be purchased without prescription in drug stores. Injection drug use occurred for 180 (81.8%) of the 220 subjects in the 12 months prior to the initial interview but in only 121 (55.0%) in the 10 months prior to the follow-up interview (p < 0.0001). Similarly, sharing of equipment decreased from 63.1% to 31.8% (p < 0.0001). Sharing with multiple partners declined from 41.9% to 10.6% (p < 0.0001). Factors associated with ongoing risk included use of injected and non-injected psychoactive substances, less time in drug dependence treatment during follow-up interval, having a sexual partner who was an IDU and not using a drug store as the primary source of syringes. Factors associated with multiple-partner sharing included use of psychoactive substances, younger age and nonwhite race.

Contingency management of urinalysis results and intensity of counseling services have an interactive impact on methadone maintenance treatment outcome.

In a 3 x 2 factorial design, 360 new admissions to methadone maintenance were randomly assigned to one of three levels of counseling: (1) "medication only," (2) "standard" counseling, and (3) "enhanced" services; and one of two contingency contracting conditions: (1) no contingencies (NC), and (2) contingency contracting (CC). Contingency contracting included discharge for continuous positive urines; subsequently CC subjects were discharged at a greater rate than the NC group. However, CC subjects were more likely to be readmitted. NC subjects provided more urines positive for any illicit drug use than did CC subjects. For opiate positives a significant level of counseling by contingency contracting interaction was found with medication only/CC subjects obtaining fewer opiate positives than medication only/NC subjects. The impact of reduced or enhanced services and of contingency contracting will not be fully understood until longer term follow-up (18 and 24 month) is completed. Results suggest that contingency management procedures could be utilized in settings offering minimum services (e.g., "interim methadone") to achieve treatment outcomes similar to programs offering standard counseling services.

Outcome of contingency contracting for illicit drug use in a methadone maintenance program.

This study evaluates the outcome of a mandatory, clinic wide, structured contingency contracting system in a methadone maintenance program. The system involved weekly urine screening and placement on written individualized contracts for any of 106 male patients who displayed illicit drug use. Methadone dose decreases were the penultimate and detoxification and discharge the ultimate contingencies for unremitting drug use. Sixty subjects (56.6%) received contracts and 36 (35%) eventually left treatment. The contracts did not decrease the overall number of positive urines for the contract subjects, but opiate use did decrease significantly for subjects on more stringent contracts.

Using drugs to facilitate sexual behavior is associated with sexual variety among injection drug users.

Little normative data exist about the frequency and variety of sexual behavior of injection drug users. Sexual behaviors of a group of 313 injection drug users (225 men and 88 women) were assessed by a structured interview at the start of an acquired immune deficiency syndrome prevention project. Celibacy was reported by 12.3% of men and 26.9% of women in the year before the initial interview. Male injection drug users who had been sexually active reported a mean number of 4.61 (median, 2.0) female sexual partners in the previous year; sexually active women reported a mean number of 5.28 (median, 1.0) male sexual partners. Sexually active men and women reported median condom use frequency at 0% of vaginal intercourse events (mean for men, 10.31%; mean for women, 14.48%). Male injection drug users who reported using drugs to help them relax for sex, to enhance sexual performance, or to meet sexual partners reported greater frequency of anal intercourse, fellatio, and cunnilingus, less relative frequency of vaginal intercourse, more sexual partners, and greater involvement in being paid for sex and paying for sex than did men who did not report using drugs to enhance sex. Men who used drugs to enhance sex also reported higher frequency of use of a number of different drug classes than men who did not use drugs to enhance sex. For women, using drugs to enhance sex was related to greater frequency of anal intercourse and having more sexual partners. Implications for treatment of drug abusers and future research are discussed.

Longitudinal sexual behavior changes in injecting drug users.

OBJECTIVE: To determine whether injection drug users (IDU) maintained sexual behavior risk reduction over an 18-month period that had been noted previously over a 4-month period. DESIGN: A repeated measures design was utilized with IDU assessed initially at study enrollment and again 18 months later. METHODS: Sexual behaviors of a group of 220 IDU (148 men and 72 women) were assessed by a structured interview at the start of an AIDS prevention project and again 18 months later. RESULTS: Having multiple sex partners during the 12 months before initial assessment was reported by 42.6% of the men and 35.7% of the women. Significantly fewer had multiple sex partners during the 10 months before follow-up assessment (men, 20.9%; women, 14.3%). Condom use for vaginal intercourse increased from a mean of 11.9% initially to 27.8% at follow-up for men. The increase in condom use was greater for those with multiple sex partners. Women did not report significant increases in condom use. Continued involvement in unsafe sexual behaviors was associated with exchanging sex for money or drugs, using drugs to help meet sexual needs, alcohol use and drug use. CONCLUSIONS: Risk reductions noted previously were maintained over 18 months for the majority of the sample. Drug-use treatment and interventions that closely examine the interplay between drug use and sexuality for individual IDU are recommended as strategies to further reduce the sexual risk of HIV transmission among IDU.

Alcohol use and high-risk behavior by intravenous drug users in an AIDS education paradigm.

The relationship between alcohol consumption and high-risk behavior for HIV infection was examined among 313 in-treatment intravenous drug users (IVDUs) by random assignment of these subjects to one of three interventions: (1) structured interview regarding risk behavior; (2) interview plus one group AIDS education session; (3) interview, AIDS education plus optional HIV testing. Alcohol users (n = 148) had more needle sharing and sexual partners than did nondrinkers. Follow-up interviews revealed no significant behavioral changes as a function of intervention condition or alcohol use. Better interventions, including more vigorous treatment of alcohol use, are needed to reduce risk behaviors among IVDUs.

Risk reduction in sexual behavior: a condom giveaway program in a drug abuse treatment clinic.

Just before and 4 months after initiation of a condom giveaway program, a questionnaire regarding sexual behavior and condom acquisition was administered to 103 men attending an outpatient drug abuse treatment clinic. Jars filled with a variety of condoms were placed in every clinic room. Condom taking varied as a function of room. Sixty percent of the subjects reported taking condoms. At follow-up, clients reported increases in condom possession and in use of condoms for vaginal intercourse.

Ineffectiveness of AIDS education and HIV antibody testing in reducing high-risk behaviors among injection drug users.

The effectiveness of education in reducing high-risk human immunodeficiency virus (HIV) transmission behaviors was examined in 313 injection drug users. Involvement in high-risk behaviors was assessed via structured interview at study entry and 4 months following the intervention. Subjects were randomly assigned to (1) AIDS education, (2) AIDS education with optional HIV antibody testing, or (3) a wait list. The sample as a whole decreased its involvement in high-risk behaviors, but there were no significant differences as a function of experimental group assignment.

Needle-use practices among intravenous drug users in an area where needle purchase is legal.

Needle-use practices of intravenous drug users (IVDUs) were examined in a region (Seattle, King Country, Washington State, USA) where needle purchase is legal. IVDUs in treatment (n = 313) were administered extensive structured interviews concerning drug and injection equipment-use practices. Of the 80.2% reporting intravenous drug use in the previous year, 78.3% reported sharing needles. Of the 47.7% reporting intravenous use in the previous 30 days, only 40.5% shared needles, with 59.3% sharing with only one other person. Most needle-sharing partners were very well known (63%) or well known (17%) to the subjects. The most frequent method for obtaining needles was 'buying in a drug store', ranked first by 65% of the sample. Subjects whose primary source was 'buying in a drug store' shared equipment less frequently during drug-use events in the previous year (mean: 16.2%) than those with other primary sources (mean: 28.5%). Compared with findings from other regions where needle purchase and possession are illegal without a prescription, fewer subjects in the current investigation shared needles, and those who did shared with a smaller number of people. The apparent association between legalized injection equipment and reduced sharing of equipment among IVDUs should be further examined in longitudinal studies of needle-sharing before and after legalization is instituted.

Urine screening practices in methadone maintenance clinics. A survey of how the results are used.

The urinalysis practices of 324 methadone maintenance clinics were surveyed using a brief self-report questionnaire. Results indicate that there is wide variability in collection practices and clinic responses to positive findings. Virtually all clinics provide counseling and revocation of take-home methadone doses as a response to positive urinalysis results. However, increase in urine screening frequency, methadone dose adjustments, contingency contracting, group therapy, and eventual discharge are interventions also used. The implementation of different interventions varied as a function of clinic size, city size, region of the country, and program funding source.

Validity of the MCMI Drug Abuse Scale varies as a function of drug choice, race, and axis II subtypes.

The validity of the Drug Abuse Scale (T) from the Million Clinical Multiaxial Inventory (MCMI) was studied by administering the MCMI to 110 male veterans seeking treatment for opioid or cocaine dependence. Only 26 and 23% of the sample obtained base rate (BR) scores above the clinical relevant cutoffs of 84 and 74, respectively. Covariables associated with elevated scores on the T Scale were Black race, presence of narcissistic/antisocial personality features, and more severe psychopathology in general. The authors urge caution in using the Drug Abuse Scale for the purpose of identifying drug abusers.

Sexual behaviors of intravenous drug users in treatment.

Sexual behaviors of a group of 313 intravenous drug users (IVDUs) (225 men, 88 women) were assessed by a structured interview at the start of an AIDS prevention project. Although the majority were celibate or monogamous during the prior year (men 52.5%, women 64.3%), many IVDUs had multiple sexual partners in that time, including 19.6% of men and 7.2% of women reporting five or more. Married male and female IVDUs were more likely to have multiple sexual partners than married people in general population samples. Only 38.5% of male and 35.4% of female IVDUs ever used condoms during the previous 5 years. Percentage of sexual encounters in which condoms were used correlated significantly with the number of partners for women (r = 0.37, p less than 0.01), but not for men (r = 0.03, ns). Use of intravenous drugs in the prior year, sharing of needles, use of stimulants, exchange of sex for money or drugs, and combining sexual events with drug use were all associated with greater numbers of sexual partners. A subset of male IVDUs engages in the dual-risk behaviors of needle sharing and unprotected intercourse with multiple partners. This group could act as a highly efficient vector for human immunodeficiency virus transmission and should become a focus of intensive preventive intervention.

Validity of the MCMI Drug Abuse Scale with drug abusing and psychiatric samples.

The validity of the Drug Abuse Scale (T) from the Millon Clinical Multiaxial Inventory (MCMI) was studied by administering the MCMI to 75 White male veterans who were seeking treatment for opioid or cocaine dependence and 60 White male veterans without diagnoses of drug dependence who were receiving psychiatric care. Only (39.4%) of the drug-abusing sample was classified correctly by obtaining base rate (BR) scores above the clinical relevant cut-off of 74, whereas, only 12% of the psychiatric sample was misclassified by having obtained a BR above 74. The results suggest that the MCMI T Scale is limited in its ability to identify drug users, but is also unlikely to misclassify psychiatric patients as drug abusers when they are not. The authors urge caution in using the Drug Abuse Scale for the purpose of identifying drug abusers.

Staffing patterns of American methadone maintenance programs.

Methadone maintenance is the most frequently utilized treatment for heroin addiction and also represents one of the best AIDS-prevention tools for the IV drug using population. Despite these important roles, very little has been reported about how methadone maintenance clinics are staffed. Surveys covering various aspects of program operations, including staffing, were sent to all clinics (N = 557) listed in the 1984 National Directory of Drug Abuse and Alcohol Treatment Programs. Using ANOVA, staffing patterns were compared across programs as a function of clinic size, city size, region of the country, and funding resources. While few differences were found based on city or clinic size, staffing patterns varied as a function of regional location as well as the sources of a clinic's funding.

Personality disorder subtypes among cocaine and opioid addicts using the Millon Clinical Multiaxial Inventory.

Individuals with psychoactive substance dependence suffer from high rates of non-substance use psychiatric disorders. These disorders sometimes prove difficult to distinguish in clinical practice. The Millon Clinical Multiaxial Inventory (MCMI) is a relatively new assessment tool which purports to evaluate DSM-III Axis I and Axis II disorders. In the present study, the MCMI was administered to 73 opioid addicts and 37 cocaine addicts entering treatment. MCMI protocols were then sorted four times to identify: (1) subjects with psychotic disturbances, (2) subjects with affective disturbances, (3) subjects with severe personality disorders, and (4) basic personality disorder subtypes. The covariabilities of all four categories with drug of choice are presented and discussed. The covariabilites of the first three categories with the fourth are also presented and discussed. The MCMI appears to be a useful instrument for psychiatric diagnosis of opioid and cocaine addicts.
