Measuring readiness for change among crack cocaine users: a descriptive analysis.

This study examines the utility of the University of Rhode Island Change Assessment Scale (URICA) in assessing stages of change status with a group of 235 crack/cocaine users who had received treatment for their drug use. Cluster analyses were performed and three subgroups representing differing levels of readiness to change were identified. The three clusters demonstrated no significant differences on most demographic characteristics and other areas of functioning assessed by the Addiction Severity Index (ASI). The three clusters also showed similar improvements between the intake and six-month follow-up in these ASI life domains. The implications of these findings are discussed.

Constructing a consensus-based prevention outcome measurement instrument.

This article describes Ohio's Prevention Evaluation Project (PEP). The purpose of the project was to develop a process and instrument to assess behavioral and attitudinal outcomes in primary drug abuse prevention programs targeting young people aged twelve to seventeen. One of PEP's principal achievements was the inclusion of community prevention program providers from throughout the state in the evaluation instrument development. The effort produced a self-administered questionnaire to capture data on young peoples' drug use practices, attitudes toward drugs, and problematic behaviors. Most significantly, the product produced was the acceptance and endorsement of community-based programs. The forty-one-item questionnaire has good to excellent reliability for virtually all measures, as assessed by the test-retest method. The instrument is a product of a process that brought together a university-based research team, state alcohol and drug abuse prevention administrators, and representatives of public programs. PEP demonstrates how to productively link service providers, administrators, and evaluators to develop a process for assessing the effectiveness of prevention programs. The process and tools described serve as a model for other communities wanting to evaluate their prevention programming.

The epidemiology of physical attack and rape among crack-using women.

This prospective study examines the epidemiology of physical attack and rape among a sample of 171 not-in-treatment, crack-cocaine using women. Since initiating crack use, 62% of the women reported suffering a physical attack. The annual rate of victimization by physical attack was 45%. Overall, more than half of the victims sought medical care subsequent to an attack. The prevalence of rape since crack use was initiated was 32%, and the annual rate was 11%. Among those women having been raped since they initiated crack use, 83% reported they were high on crack when the crime occurred as were an estimated 57% of the perpetrators. Logistic regression analyses showed that duration of crack use, arrest for prostitution, and some college education were predictors of having experienced a physical attack. Duration of crack use and a history of prostitution were predictors of suffering a rape. Drug abuse treatment programs must be sensitive to high levels of violence victimization experienced by crack-cocaine using women. Screening women for victimization, and treating the problems that emanate from it, may help make drug abuse treatment more effective.

The Ohio Substance Abuse Monitoring Network: constructing and operating a statewide epidemiologic intelligence system.

Working with the Ohio Department of Alcohol and Drug Addiction Services (ODADAS) and researchers at the University of Akron, Wright State University's Center for Interventions, Treatment, and Addictions Research developed the Ohio Substance Abuse Monitoring (OSAM) Network to provide a statewide summary of substance abuse trends. Ten key informants across the state collect qualitative and statistical data on substance abuse trends in their regions and prepare biannual reports. The OSAM network has a rapid response capability through which key informants can investigate special issues related to substance abuse identified by ODADAS and provide policymakers with timely, statewide reports. Within 12 months after operations began, the key informants produced reports on drug abuse trends and rapid response issues for the state. These reports prepared policymakers to respond more effectively to prevention and substance abuse treatment needs.

Risk and prevalence of treatable sexually transmitted diseases at a Birmingham substance abuse treatment facility.

OBJECTIVES: We evaluated the prevalence of gonorrhea, chlamydia, trichomoniasis, and syphilis in patients entering residential drug treatment. METHODS: Data on sexual and substance abuse histories were collected. Participants provided specimens for chlamydia and gonorrhea ligase chain reaction testing. Trichomonas vaginalis culture, and syphilis serologic testing. RESULTS: Of 311 patients, crack cocaine use was reported by 67% and multisubstance use was reported by 71%. Sexually transmitted disease (STD) risk behaviors were common. The prevalence of infection was as follows: Chlamydia trachomatis, 2.3%; Neisseria gonorrhoeae, 1.6%; trichomoniasis, 43%; and syphilis, 6%. CONCLUSIONS: STD counseling and screening may be a useful adjunct to inpatient drug treatment.

Crack-cocaine use and health status as defined by the SF-36.

The Medical Outcomes Study Short Form 36 (SF-36) was administered to 443 not-in-treatment, crack-cocaine smokers to explore the relationship between frequency of crack, alcohol, and tobacco use, addiction to these drugs, and health status. The reliability of the SF-36 with crack smokers was also assessed. Statistically significant, negative associations emerged between frequency of crack use and all SF-36 subscales except physical functioning. There were not significant associations between frequency of alcohol or tobacco use and any SF-36 subscale. Self-assessed addiction to crack was strongly and negatively associated with all SF-36 subscales: alcohol and tobacco addiction were also negatively associated with health status, but not to the degree of crack. The SF-36 produces reliable data on the health status of crack users and, as such, may have a useful role in assessments involving crack-using populations.

Longitudinal application of the medical outcomes study 36-item short-form health survey with not-in-treatment crack-cocaine users.

BACKGROUND: The Medical Outcomes Study SF-36 has been used infrequently with substance abusers. OBJECTIVES: The objectives of this study were to use the SF-36 to assess changes in the health status of crack-cocaine users over time, to determine the characteristics of users who change, to assess the influence of frequency of crack use on SF-36 health status, and to determine the utility of the SF-36 with crack users. DESIGN: A multilevel model was used to analyze data that were collected every 6 months over a 2-year period. SUBJECTS: The sample consisted of 439 not-in-treatment crack-cocaine users. MEASURES: The SF-36 was administered at baseline and follow-up interviews. Data on the frequency of crack-cocaine use were also collected. RESULTS: On average, SF-36 health status remained fairly static during the study although statistically significant increases in scores occurred on the social functioning and role-emotional subscales. Variation in subjects' health trajectories occurred but was not, for the most part, explained by individual characteristics. Frequency of crack use was negatively related to scores on the physical functioning, social functioning, and mental health subscales. Most subscales did not reflect what are commonly recognized to be the health-compromising effects of cocaine use, raising questions about the use of the SF-36 with illicit drug users. CONCLUSIONS: Changes in crack users' SF-36 health status were uncommon. Frequency of crack use was negatively associated with health status. Several SF-36 subscales may be helpful in studies involving illicit drug users in which limited assessments of health status are needed.

Standardization and decomposition of rates: useful analytic techniques for behavior and health studies.

Standardization and decomposition are widely used analytic techniques in population studies for adjusting the impact of compositional factors on rates. This study demonstrates the application of these methods to behavior and health studies. Bootstrapping is used to estimate standard errors of the component effects and to conduct significance tests for them. The authors have developed a Windows-based computer program that is demonstrated in the study for standardization and decomposition analysis by using empirical data on HIV seropositivity rates in two injection-drug-using populations in the northeastern United States.

Crack-cocaine users as victims of physical attack.

This study evaluates the correlates of physical attack among people who use crack cocaine in Dayton, Ohio. Using a retrospective and prospective natural history design, data from baseline and 1-year follow-up interviews were used to calculate the prevalence of physical attack and the annual rate of physical attack suffered by 440 not-in-treatment crack-cocaine users. Logistic regression was used to determine the correlates of physical attack. The lifetime prevalence of physical attack was 63.0%; the annual rate was 36.8%. At baseline, daily crack users were more likely to report a previous attack since they began using crack (odds ratio [OR], 1.81; 95% confidence interval [CI], 1.18-2.77). Longer duration of crack use was also associated with experiencing an attack (OR, 1.09; 95% CI, 1.04-1.14). Between baseline and 12-month follow-up, the odds of men being attacked were significantly less than those for women (OR, 0.48; 95% CI, 0.23-0.99). Physical attack is widespread among crack-cocaine users, and does not vary by ethnicity. Injuries often result in the need for medical care. Over the short term, women are at increased risk. Accessible and effective drug abuse treatment is needed to diminish the harm this population suffers.

Can a brief clinical practicum influence physicians' communications with patients about alcohol and drug problems? Results of a long-term follow-up.

BACKGROUND: A survey was conducted in 1996 to assess the perceptions of medical school graduates concerning alcohol and drug problems among their patients, and their attitudes and comfort toward addressing these issues. Survey questionnaires were sent to all individuals who graduated from Wright State University School of Medicine, Dayton, Ohio, between 1982 and 1990. PURPOSE: The study aimed to assess the long-term impact that participation in a brief clinical experience in tandem with a standard didactic substance abuse curriculum material had on former medical students now in practice. The study examined how these physicians perceived their skills in communicating with their patients about alcohol and drug use, and attendant problems. METHODS: An Alcohol and Drug Use Communication (ADUC) scale was developed by combining several survey items. Data analyses included correlation assessments of the ADUC scale and other variables, and multiple-regression analyses for identifying factors independently associated with the ADUC scale although other factors were controlled. RESULTS: Former students who participated in the brief clinical program, known as the Weekend Intervention Program, as part of their medical school curriculum were more likely to report having better communication concerning alcohol and drug use with their patients than students who only had didactic education. Also, additional training in addictions after graduation was significantly associated with better alcohol and drug use communication between physician and patient. Former students who participated in the Weekend Intervention Program were more than twice as likely as those without the experience to report confronting at least 10% of their patients about their concerns about the patients' alcohol or drug use. CONCLUSIONS: The results of this study suggest that undergraduate medical students' participation in a modest clinical program can enhance substance abuse education. Through increased training in substance abuse, physicians reported greater confidence in their ability to relate to patients with substance abuse problems.

HIV needle risk behaviors and drug use: a comparison of crack-smoking and nonsmoking injection drug users in Ohio.

This study compares the drug use and needle risk behaviors among 733 crack-smoking injection drug users (IDUs) and 518 nonsmoking IDUs. Participants were recruited in Dayton and Columbus, Ohio, for the Cooperative Agreement for AIDS Community-Based Outreach/Intervention Research Program from 1992 to 1996. Crack-smoking IDUs were more likely to be male, African-American, and 30 to 40 years of age, but less likely to be married or living with a sex partner compared to nonsmokers. Daily crack users were less likely to be daily injectors but more likely to use alcohol daily when compared to non-crack users and less-than-daily crack smokers. IDUs who smoked crack less than daily were more likely to have injected with needles and syringes used by others. There is an urgent need for additional research on the relationship between drug injection and crack smoking as well as improved HIV risk-reduction interventions that include drug abuse treatment components focusing on issues surrounding crack-cocaine addiction.

Differences in drug use among rural and suburban high school students in Ohio.

This exploratory study examines differences in the prevalence of drug use by gender among twelfth grade students (n = 464) in selected rural and suburban high schools in west-central Ohio. The lifetime use of alcohol and other drugs is common among all groups. Proportionally fewer boys in rural schools than boys in suburban schools reported the use of marijuana, inhalants, and LSD, or recent episodes of drunkenness. No statistically significant differences emerged between girls in rural and suburban schools. Afterschool employment practices may help explain the observed differences.

Under the influence: risky sexual behavior and substance abuse among driving under the influence offenders.

BACKGROUND AND OBJECTIVES: The purpose of this study was to examine the associations between alcohol and drug abuse and risky sexual practice in a sample of 366 driving under the influence (DUI) offenders. STUDY DESIGN: Data were collected from a sample of participants at a university-operated drunk driving intervention program. Specific indicators included established or severe alcohol/drug use problems, multiple drugs used, multiple alcohol/drug related arrests, and early regular alcohol use. Multiple sexual partners, condom use, and having sex while under the influence of alcohol or drugs were used to measure risky sexual behavior patterns. Correlation and logistic regression analyses examined associations between these substance abuse and sexual risk taking measures. RESULTS: Substance abuse in general was unrelated to risky sexual behavior such as multiple sexual partners or lack of condom use. However, having sex while high from alcohol or drugs was significantly associated with substance abuse. Moreover, having sex while high was significantly related to both risky sex and a history of sexually transmitted disease. CONCLUSIONS: Having sex while high may be an important behavior to address to prevent STDs in the DUI population. Assessing relationships between substance abuse and risky sexual behavior poses a challenge to researchers because any estimates about this association may be dependent on the measure of sexual behavior that is used. An integrated intervention approach that addresses both substance abuse prevention and safe sexual practice appears crucial and effective for educating "risk takers" such as DUI offenders. However, these data caution that for those who are dependent upon alcohol and/or other drugs, education solely emphasizing risk reduction procedures is likely to be inefficient until their chemical dependency is addressed.

Evaluation of HIV risk reduction intervention programs via latent growth model.

The latent growth model (LGM) has drawn increasing attention in behavioral studies using longitudinal data. The LGM captures the level and trajectory of behavior change, variation in both the initial status and the trend of behavior change, as well as the time-ordered covariation between the initial status and change. This study demonstrates how the LGM can be applied in the evaluation of intervention programs targeting HIV risk behavior among drug users. Multi-group piecewise latent growth models were fit to longitudinal data with three repeated response measures.

Predicting postprimary treatment services and drug use outcome: a multivariate analysis.

The substance abuse treatment field is continually challenged to develop interventions that encourage drug abusers to remain longer in therapeutic services and that facilitate improved outcomes. As one of those interventions, case management has generally not been subjected to multivariate analysis to evaluate its role in accomplishing those goals. Using a sample of 444 veterans who received substance abuse treatment services, this study examines relationships among demographic and psychosocial variables at intake, assignment to either traditional or enhanced (case management) treatment services, and both proximal (postprimary treatment contact) and distal (severity of drug use) measures of outcome. Multivariate analyses reveal that case-managed clients stay longer in postprimary treatment services than non-case-managed clients, and consequently, longer postprimary treatment contact leads to better drug use outcomes. The implications of these findings are discussed.

Feasibility of obtaining sexual risk and STD history in the context of a drinking drivers' program.

OBJECTIVES: This study was designed (a) to assess the feasibility of obtaining data about sexually transmitted diseases and sexual risk behavior in an alternative-to-incarceration program for convicted drinking drivers and (b) to determine whether asking health history and sexual risk questions using an anonymous questionnaire, anonymous interviews, or confidential interviews affected the willingness of people to participate. METHODS: The same survey instrument was used across three data collection modes to collect information on sexually transmitted diseases and sexual risk behavior. RESULTS: Overall, there were no differences across modes in self-reports of STDs and details of sexual history. Although the difference in refusal rates between the anonymous questionnaire and the anonymous interview was not significant, the refusal rate for the anonymous questionnaire was significantly higher than the rate for the confidential interview. Those answering the self-administered questionnaire were more likely than those receiving face-to-face interviews to refuse to answer questions about having sex while high and condom use. CONCLUSIONS: A drinking driver intervention program may be an appropriate site for health screenings and prevention activities for an at-risk population.

Needle transfer among injection drug users: a multilevel analysis.

OBJECTIVE: The purpose of the study described here is to extend our understanding of needle transfer behaviors among injection drug users (IDUs) by combining both micro and macro variables in a multilevel model. METHODS: A sample of 8,404 IDUs interviewed at 18 sites of the National Institute on Drug Abuse (NIDA) Cooperative Agreement for AIDS Community-Based Outreach/Intervention Program (COOP) was used for the study. A multilevel model was employed to deal with intraclass correlation in the sample and to evaluate the impact of micro and macro variables on needle transfer among IDUs. RESULTS: A significant intraclass correlation was detected in the sample. Needle transfer was associated with both the individual characteristics and the features of the social setting in which they were embedded. Some of the micro slopes were fixed, while some varied from site to site, depending on the values of macro variables. The micro intercept and the micro slope of ethnicity vary randomly across social settings, while they are partially determined by macro variables. CONCLUSION: Considering the intraclass correlation in the data and the effects of contextual features on individual behaviors, multilevel analysis of HIV risk behaviors should be considered when combining data from micro and macro levels (e.g., individual and project site levels).

A preliminary evaluation of a modified needle-cleaning intervention using bleach among injection drug users.

This study examines an intervention designed to improve needle-cleaning practices among injection drug users (IDUs) in Dayton and Columbus, Ohio, to meet the recommended bleach exposure time of at least 30 seconds. Simulated needle-cleaning practices were observed in offices at baseline and after an intervention at 2 to 4 week and 6-month follow-ups. Descriptive statistics, t-tests, logistic, and multiple regressions were used to examine behavior change and the correlates of safer cleaning practices. At baseline (n = 541), the mean bleach exposure time was 13.8 seconds. At first follow-up (n = 410), the mean bleach contact time (23.4 s) increased significantly (t = 8.59; p < .05). At 6-month follow-up (n = 83), the mean bleach exposure time (21.1 s) also increased significantly (t = 2.98; p < .05). Longer bleach contact time was associated with higher injection frequency and needle transfer at 6-month follow-up. Although mean bleach exposure time increased significantly at both follow-ups, only 30.3% of the IDUs kept bleach in the syringe for at least 30 seconds at 6-month follow-up. Improved interventions are needed.

Factors influencing condom use among heterosexual users of injection drugs and crack cocaine.

OBJECTIVES: To study factors that influence the self-reported use of condoms among injection drug users and crack smokers. STUDY DESIGN: A cross-sectional design was used to collect data from drug-using heterosexual men (n = 247) and women (n = 107). RESULTS: Participants were largely African American (79.4%), male (69.8%), and unmarried (90.1%). The mean age for men was 39.9 years, 35.5 years for women. Drug user groups consisted of individuals who used both crack cocaine and injection drugs (40.1%), noninjecting crack smokers (33.1%), and non-crack-smoking injection drug users (26.8%). Daily injection drug or crack use was reported by 62.9% of the sample. One third of the sample reported recent vaginal sex with more than one partner. More than 70% of the participants frequently used drugs when having sex. Logistic regression showed that individuals who were high when having vaginal sex were less likely to use condoms than people who were not high (odds ratio [OR] 0.82; 95% confidence interval [CI], 0.68-0.99); individuals whose partners got high when having sex were more likely to report condom use (OR 1.20; 95% CI, 1.01-1.42); individuals were less likely to use condoms when having sex with a main partner (OR 0.40; 95% CI, 0.20-0.80); individuals who believed it was important to use condoms were more likely to use condoms (beta = 0.57, P < 0.00); and people who believed condoms reduced sexual pleasure were less likely to use condoms (beta = -0.53, P < 0.00). CONCLUSIONS: In addition to being sensitive to partner characteristics, sex risk-reduction interventions targeting users of injection drugs or crack must address the widespread use of psychoactive drugs that occurs immediately before and during sex because such use presents a significant impediment to the employment of safer-sex techniques that rely on condoms. Until such interventions are in place, access to drug abuse treatment is a critical dimension of human immunodeficiency virus and other sexually transmitted disease prevention.

History of sexually transmitted diseases infection, drug-sex behaviors, and the use of condoms among midwestern users of injection drugs and crack cocaine.

BACKGROUND AND OBJECTIVES: This study describes self-reported histories of sexually transmitted diseases (STD) with respect to gender and ethnicity and examines the factors that influence the use of condoms among heterosexual users of injection drugs and/or crack cocaine. STUDY DESIGN: A cross-sectional design was used to interview 1046 active users of illicit drugs living in Columbus and Dayton, Ohio. RESULTS: STD was common among 29% of the white men, 53.6% of the black men, 55.9% of the white women, and 64.7% of the black women self-reporting previous infection. Among women, stepwise logistic regression showed that cohabitating with a spouse or a sex partner (OR 0.28; 95% CI, 0.06 to 0.77) and exchanging sex for drugs (OR 0.31; 95% CI, 0.11 to 0.88) were associated negatively with always using a condom during vaginal sex in the previous month, whereas exchanging sex for money (OR 4.48; 95% CI, 1.88 to 10.95) was associated positively. Among men, cohabitating with a spouse or a sex partner (OR 0.13; 95% CI, 0.06 to 0.31), having had an STD (OR 0.53; 95% CI, 0.33 to 0.85), and currently using injection drugs (OR 0.52; 95% CI, 0.33 to 0.84) were associated negatively with condom use. CONCLUSIONS: Users of illicit drugs are at high risk for the acquisition and transmission of STD. More research is needed to understand better the sex practices of users of injection drugs and crack cocaine so that appropriate interventions can be developed.

PIP: During 1992-95, in Ohio, outreach workers at various sites in Dayton and Columbus interviewed 749 men and 297 women about their drug use practices, sexual behaviors, drug-sex behaviors, and history of some sexually transmitted diseases (STDs). Researchers aimed to assess baseline behaviors of injection drug users and crack cocaine users. 73.2% of the men and 57.2% of the women used injection drugs. 26.8% of the men and 42.8% of the women used crack cocaine. About 25% of both groups were homeless. 79.7% of men and 68.7% of the women were Black. Among men, Blacks were more likely than Whites to have had syphilis and gonorrhea or any STD (6.2% vs. 2%, 48.6% vs. 19.1%, and 53.6% vs. 29%, respectively; p 0.05). Among women, Blacks were more likely to have had trichomonas (40.2% vs. 26.1%; p 0.05). For men, variables associated with not always using condoms in the last 30 days included STD history (odds ratio [OR] = 0.53; p = 0.0069), cohabitation (OR = 0.13; p = 0.00001), and injection drug use (when compared with crack cocaine use) (OR = 0.52; p = 0.0063); for women, they were exchanging sex for drugs (OR = 0.31; p = 0.0252) and cohabitation (OR = 0.22; p = 0.0157). Women who traded sex for money were significantly more likely to always use condoms in the last 30 days than those who did not (OR = 4.48; p = 0.0008). These findings show that injection drug users and crack cocaine users face a high risk of acquiring and transmitting STDs. They suggest that intervention efforts to target these two groups need to be sensitive to ethnic and gender differences.
