Risky Sexual Behaviors, Substance Use, and Perceptions of Risky Behaviors Among Criminal Justice Involved Women Who Trade Sex.

This study examined risky sexual behaviors, Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV)-defined alcohol and substance use disorders, and perceptions of risky behaviors among community released, justice-involved women, who are currently trading sex (CTS), formerly traded sex (FTS), or have never traded sex. Data were derived from 266 sexually active women recruited from a Municipal Drug Court System in St. Louis, Missouri. In an adjusted multinomial regression model, being dependent on alcohol and cocaine was the most robust correlate of sex-trading status (adjusted odds ratio [AOR]: CTS = 4.21, FTS = 4.66). Perceptions of sexual risk and HIV were significantly associated with CTS (AOR = 3.39), however, not FTS. Other significant correlates of sex trading status included age, lifetime injection drug use, lower education, child sexual abuse, and unstable housing. Gender-specific interventions tailored toward currently and formerly sex-trading women are needed.

Baseline brain function in the preadolescents of the ABCD Study.

The Adolescent Brain Cognitive Development (ABCD) Study® is a 10-year longitudinal study of children recruited at ages 9 and 10. A battery of neuroimaging tasks are administered biennially to track neurodevelopment and identify individual differences in brain function. This study reports activation patterns from functional MRI (fMRI) tasks completed at baseline, which were designed to measure cognitive impulse control with a stop signal task (SST; N = 5,547), reward anticipation and receipt with a monetary incentive delay (MID) task (N = 6,657) and working memory and emotion reactivity with an emotional N-back (EN-back) task (N = 6,009). Further, we report the spatial reproducibility of activation patterns by assessing between-group vertex/voxelwise correlations of blood oxygen level-dependent (BOLD) activation. Analyses reveal robust brain activations that are consistent with the published literature, vary across fMRI tasks/contrasts and slightly correlate with individual behavioral performance on the tasks. These results establish the preadolescent brain function baseline, guide interpretation of cross-sectional analyses and will enable the investigation of longitudinal changes during adolescent development.

Substance use patterns in 9-10 year olds: Baseline findings from the adolescent brain cognitive development (ABCD) study.

BACKGROUND: The Adolescent Brain Cognitive Development ™ Study (ABCD Study®) is an open-science, multi-site, prospective, longitudinal study following over 11,800 9- and 10-year-old youth into early adulthood. The ABCD Study aims to prospectively examine the impact of substance use (SU) on neurocognitive and health outcomes. Although SU initiation typically occurs during teen years, relatively little is known about patterns of SU in children younger than 12. METHODS: This study aims to report the detailed ABCD Study® SU patterns at baseline (n = 11,875) in order to inform the greater scientific community about cohort's early SU. Along with a detailed description of SU, we ran mixed effects regression models to examine the association between early caffeine and alcohol sipping with demographic factors, externalizing symptoms and parental history of alcohol and substance use disorders (AUD/SUD). PRIMARY RESULTS: At baseline, the majority of youth had used caffeine (67.6 %) and 22.5 % reported sipping alcohol (22.5 %). There was little to no reported use of other drug categories (0.2 % full alcohol drink, 0.7 % used nicotine, <0.1 % used any other drug of abuse). Analyses revealed that total caffeine use and early alcohol sipping were associated with demographic variables (p's<.05), externalizing symptoms (caffeine p = 0002; sipping p = .0003), and parental history of AUD (sipping p = .03). CONCLUSIONS: ABCD Study participants aged 9-10 years old reported caffeine use and alcohol sipping experimentation, but very rare other SU. Variables linked with early childhood alcohol sipping and caffeine use should be examined as contributing factors in future longitudinal analyses examining escalating trajectories of SU in the ABCD Study cohort.

Posttraumatic stress disorder among substance users from the general population.

OBJECTIVE: The purpose of the study was to evaluate the prevalence of posttraumatic stress disorder (PTSD) among substance users in the general population. METHOD: The St. Louis Epidemiologic Catchment Area study, a survey of psychiatric illness in the general population, collected data on PTSD and substance use with the Diagnostic Interview Schedule. Among the 2,663 respondents, 430 reported a traumatic event that could qualify for PTSD; however, the rate of PTSD was low, 1.35% overall. To evaluate the relationship between PTSD and substance use, respondents were hierarchically classified into one of four substance use categories ranging from polydrug use to alcohol use only. Substance users from each category as well as substance users in general were compared with persons who did not meet the substance use threshold (comparison subjects). RESULTS: Findings indicate that cocaine/opiate users are over three times as likely as comparison subjects to report a traumatic event, report more symptoms and events, and are more likely to meet diagnostic criteria for PTSD. Physical attack, but not combat-related events, was the most prevalent event reported among cocaine/opiate users. Onset of substance use preceded onset of posttraumatic symptoms, suggesting that substance use predisposes the individual to exposure to traumatic events. When other variables--including antisocial behavior--were controlled, female gender and use of cocaine/opiates predicted PTSD. CONCLUSIONS: These analyses of the co-occurrence of substance abuse and PTSD warrant further study and suggest that PTSD is much more common among substance abusers than was previously known.

Comparing DSM-III-R and ICD-10 substance use disorders.

At the present, the DSM-III-R is nearing the final stages of metamorphosis to DSM-IV. A series of field trials has been completed which has focused the attention on coverage of the different systems, the impact of social and legal problems on crossing the diagnostic threshold, the importance of subtyping by tolerance and withdrawal, the exclusionary diagnosis of abuse, the duration criterion, and other nosological comparisons. The focus of this Data Note is the comparison of rates between DSM-III, III-R, and both the old and new ICD-10 diagnostic systems, using data from the DSM-IV Substance Use Disorders Field Trials. Especially noteworthy is the inclusion of African Americans, females, and a population with a range of diagnoses and use patterns. Comparisons of DSM-III, III-R and ICD-10 substance use diagnoses among alcohol, nicotine, cannabis, cocaine substance users indicate considerable agreement for dependence but less similarities between systems for abuse and harmful use. These findings suggest that the dependence criteria may be more stable than those chosen to represent abuse and harmful use. More work needs to be done to evaluate the differences and similarities of the diagnostic systems.

Severity of dependence: data from the DSM-IV field trials.

The concept of a dependence syndrome with graded levels of severity was originally derived from work with alcoholics. The applicability and clinical utility of the dependence syndrome across a wider range of substances was examined as part of the DSM-IV field trials. When using a criterion count method to assess severity, it was found that persons cluster at different severity levels according to the drug on which they are dependent. Across all drug classes, severity correlated reasonably well with measures of quantity and frequency of use and with associated problems. The relationship between severity ratings and outcome was not tested, however data from other studies indicate that severity is only one of many factors that can influence outcome.

Alcohol abuse and dependence: consistency in reporting of symptoms over ten years.

The present study assesses the stability of the diagnosis of alcoholism among a sample of St Louis, USA Epidemiological Catchment Area Study participants. The Diagnostic Interview Schedule was used at Time 1 and the Composite International Diagnostic Interview--Substance Abuse Module was used at 10-year follow-up. Alcohol abuse and dependence were diagnosed using DSM-III criteria. Kappa values and Yule's statistics for agreement in diagnoses, criterion groups and individual symptoms are reported. Fair to good measurement of agreement was shown for any diagnosis of alcohol abuse or dependence versus no diagnosis. The criterion group for "impairment in social or occupational functioning" showed the highest agreement of the three criterion groups studied. Agreement was lower for individual symptoms of alcoholism. Incident cases accounted for some of the inconsistency in responses over 10 years. Other types of inconsistency found were changing response from yes to no, changing response from no to yes but not meeting the definition of an incident case, and misstating age of onset of symptoms. Mean per cent inconsistency across all symptoms was 11.4%. Further research regarding reasons for inconsistencies is needed.

Inhalant use among urban American Indian youth.

AIMS: To assess the prevalence of inhalant use among urban American Indian youth and to examine differences between inhalant users and non-users. DESIGN: Baseline (T1) self-report questionnaires completed in 5th-6th grade and at seven annual follow-up assessments (T2-T8). SETTINGS: Seattle metropolitan area. PARTICIPANTS: Two hundred and twenty-four Indian youth. MEASUREMENTS: Youth-completed measures of substance use, ethnic self-identity, involvement in traditional Indian activities, family conflict, family history of alcoholism, peer and sibling deviance, self-esteem, delinquency, aggression, anxiety, depression, sensation seeking, conduct disorder and alcohol dependence. FINDINGS: Lifetime inhalant use was reported by 12.3% of adolescents. At T1, inhalant users had significantly lower perceived self-worth and average annual household incomes and significantly greater density of familial alcoholism and expression of aggressive and delinquent conduct than non-users. Aggressive behavior was the most important T1 predictor of inhalant use. Lifetime conduct and alcohol dependence disorders were 3.3 and 2.6 times more prevalent among inhalant users than non-users at T5. Inhalant users had more extensive deviant peer networks, were more sensation-seeking, and evidenced lower perceived self-worth than non-users at T8. CONCLUSIONS: Inhalant use was less prevalent in this particular sample of urban Indian adolescents than in most studies of reservation Indian youth. As with other studies of inhalant abuse, aggressive and delinquent males of low SES and low-perceived self-worth with family histories of alcohol dependence, were at highest risk for inhalant use.

Childhood victimization and drug abuse: a comparison of prospective and retrospective findings.

This study examined whether childhood victimization increases risk for drug abuse using prospective and retrospective victimization information. Substantiated cases of child abuse/neglect from 1967 to 1971 were matched on gender, age, race, and approximate social class with nonabused/nonneglected children and followed prospectively into young adulthood. Between 1989 and 1995, 1,196 participants (676 abused/neglected and 520 control) were administered a 2-hr interview, including measures of self-reported childhood victimization and drug use/abuse (the National Institute of Mental Health Diagnostic Interview Schedule--Version III--Revised). Prospectively, abused/neglected individuals were not at increased risk for drug abuse. In contrast, retrospective self-reports of childhood victimization were associated with robust and significant increases in risk for drug abuse. The relationship between childhood victimization and subsequent drug problems is more complex than originally anticipated.

Reliability of substance use disorder diagnoses among African-Americans and Caucasians.

Cross cultural research on substance use disorders (SUD) demands diagnostic measures and criteria that apply equally well to persons of different ethnic backgrounds. To evaluate the reliability of SUD in different ethnic groups, comparisons were made of the one week test/retest agreement on DSM-IV lifetime dependence disorders for 196 African-American (AA) and 107 Caucasian (C) respondents using the Composite International Diagnostic Interview-Substance Abuse Module (CIDI-SAM). Overall we found excellent reliability, using kappa (k) statistics, in diagnosing both AA and C respondents with alcohol dependence (AA k = 0.78; C k = 0.80) and opiate dependence (AA k = 0.77; C k = 0.71), good reliability for diagnosing both AA respondents (k = 0.63) and C respondents with cocaine dependence (k = 0.67), and to good reliability for both AA and C respondents with cannabis dependence (AA k = 0.50; C k = 0.69). Reliability of the dependence/abuse criteria was consistent with the overall diagnostic reliability but some variation was noted. No significant differences in the kappas were found between the two ethnic groups for any of the substance dependence diagnoses, and only one dependence or abuse criterion (continued use of cocaine despite physical/psychological problems) differed significantly between AA and C respondents. These initial results indicate that DSM-IV dependence diagnoses as measured by the CIDI-SAM apply equally well to AA and C respondents.

Agreement between DSM-III and III-R substance use disorders.

With proposed criteria for DSM-IV substance dependence imminent, an evaluation of the impact of changes from DSM-III to DSM-III-R would be informative. Recent admissions to St. Louis drug treatment centers were interviewed with the DIS-III-R, which covers criteria from both systems. Kappa values for system agreement, diagnostic overlap and percent positive agreement are reported by substance. The DSM-III-R system cast a wider net for dependence than DSM-III for alcohol, tobacco and amphetamines. Neither system predominated for cannabis, opioids and barbiturates/sedatives/hypnotics. Reasons for differences and implications of findings are discussed.

Is antisocial personality disorder associated with increased HIV risk behaviors in cocaine users?

Previous reports have shown antisocial personality disorder (ASPD) to be strongly associated with injection equipment sharing and increased rates of human immunodeficiency virus (HIV) infection in a sample of heroin injectors. Another report has shown ASPD to be associated with injection drug use, needle sharing, sexual promiscuity, and prostitution in a sample of methadone maintenance clients. The current study extends this work by examining the relationship of ASPD and human immunodeficiency virus (HIV) risk behaviors in a sample of cocaine users (48% out of treatment and 52% just entering treatment). Associations were tested for sexually risky behaviors in addition to injection behaviors. The principle finding of this study is that ASPD was shown to be associated with increased rates of injection drug use and sharing syringes, with earlier age of onset of injection drug use, with certain venereal diseases, and with a variety of HIV risk sexual behaviors. When men and women were tested separately, the pattern of association of risky behaviors with ASPD varied considerably. Overall, this work confirms that psychiatric status, especially the presence of ASPD, may have to be considered in evaluating the results of HIV risk-reduction interventions.

Comparing assessments of DSM-IV substance dependence disorders using CIDI-SAM and SCAN.

The main question addressed by this paper is whether DSM-IV substance dependence diagnoses obtained from two different instruments (the semi-structured WHO Schedules for Clinical Assessment in Neuropsychiatry, SCAN and the highly structured WHO Composite International Diagnostic Interview--Substance Abuse Module, SAM) are as consistent as diagnoses obtained from a single instrument (SAM) administered twice. Such comparisons of results from the two different instruments provide some measure of validity of the lay-administered SAM and of the underlying diagnostic concepts. Chance-corrected concordance was estimated using the kappa coefficient for SAM/SCAN (test/validation) and SAM/SAM (test/retest) comparisons. Analyses of agreement between SAM and SCAN for DSM-IV dependence diagnoses indicated good agreement for alcohol and cocaine, and fair agreement for opiates and cannabis. SAM/SAM (test/retest) agreement was excellent for alcohol and opiate dependence, good for cocaine dependence, and fair for cannabis dependence. Agreement on individual dependence criteria was generally consistent with overall diagnostic agreement though more variable. Notable was the poor agreement for cannabis criteria in the SAM/SCAN protocol. This may indicate that the dependence syndrome is less applicable to cannabis, while the consistency of agreement for alcohol, opiate, and cocaine dependence criteria supports the validity of these dependence syndromes. Finally, these data indicate that both the clinical (SCAN) and non-clinical (SAM) interviews can be used effectively for a variety of substances and dependence diagnoses.

Achieving a 96.6 percent follow-up rate in a longitudinal study of drug abusers.

Longitudinal studies can be hampered by poor follow-up rates, seriously reducing generalizability of the findings. Understanding the barriers, as well as approaches to overcome and adapt to these impediments, resulted in a 96.6% 18 month follow-up rate of 479 drug abusers enrolled in an NIDA funded demonstration project aimed at reducing HIV transmission among St. Louis' most vulnerable drug-using population. In this paper, we discuss the importance of phone and systems tracking, creative team work and persistence and procedures for tracking out-of-treatment drug-users by analyzing the efforts needed to reach the study subjects. We also compared the characteristics of hard-to-reach respondents with those who were less difficult. The results revealed that employment status was the only characteristic associated with being hard-to-reach. Gender, race, age, education and psychiatric status did not discriminate recruitment difficulty in this sample. The study findings suggest that although unemployment predicted recruitment difficulty, and that the locator information provided by the respondent can be very helpful, a comprehensive tracking strategy as well as persistence and creative team work are the most important determinants of the rate of success of a follow-up investigation.

Reliability of self-reported antisocial personality disorder symptoms among substance abusers.

It is estimated that from 20 to 60% of substance abusers meet criteria for Antisocial Personality Disorder (APD). An accurate and reliable diagnosis is important because persons meeting criteria for APD, by the nature of their disorder, are less likely to change behaviors and more likely to relapse to both substance abuse and high risk behaviors. To understand more about the reliability of the disorder and symptoms of APD, the Diagnostic Interview Schedule Version III-R (DIS) was administered to 453 substance abusers ascertained from treatment programs and from the general population (St Louis Epidemiological Catchment Area (ECA) follow-up study). Estimates of the 1 week, test-retest reliability for the childhood conduct disorder criterion, the adult antisocial behavior criterion, and APD diagnosis fell in the good agreement range, as measured by kappa. The internal consistency of these DIS symptoms was adequate to acceptable. Individual DIS criteria designed to measure childhood conduct disorder ranged from fair to good for most items; reliability was slightly higher for the adult antisocial behavior symptom items. Finally, self-reported 'liars' were no more unreliable in their reports of their behaviors than 'non-liars'.

Cocaine users with antisocial personality improve HIV risk behaviors as much as those without antisocial personality.

Previous work has documented that antisocial personality disorder (APD) is associated with increased rates of HIV risk behaviors and with worse substance abuse treatment outcomes. The question addressed by this paper is whether cocaine users with APD respond to an HIV risk-reduction intervention as well as cocaine users without the disorder. The study subjects were 333 cocaine users followed up at 18 months as part of a NIDA-funded treatment demonstration project. The total sample improved across a wide range of HIV risk behaviors. Improving significantly (P < 0.05) from baseline to the 18-month follow-up were several drug-related behaviors: cocaine use; current cocaine dependence; use of drugs other than cocaine drug injection; injection equipment sharing; and use of syringes that were not cleaned. Several sex-related HIV risk behaviors also improved significantly: having multiple sex partners; being intoxicated during sex; giving drugs for sex; receiving money for sex; and receiving drugs for sex. When the sample was stratified by APD status, very similar improvement was seen in respondents with and without APD. To examine further the relationship of APD to change in HIV risk behaviors, separate logistic regression models of improving and worsening HIV risk behaviors were tested. What the authors found was no association of APD with improvement in HIV risk behaviors but a significant association of APD with worsening HIV risk behaviors. It appears that cocaine users with APD improve their HIV risk behaviors just as much as those without APD but may be at higher HIV risk for the development of such behaviors.

Self-report stability for substance use over 10 years: data from the St. Louis Epidemiologic Catchment Study.

In substance abuse research many study protocols require the recall and report of behavior from the distant past that may affect reliability. This study addresses the stability of substance use reports over a 10-year follow-up period. We reinterviewed 223 ECA subjects who reported baseline drug use. Reports from baseline to follow-up were categorized as either incident cases, agreements, or discrepancies. Different patterns were found for each substance group. The authors found that cannabis, cocaine, sedatives, and opiates had high agreement rates ranging from 82-86% and amphetamines had the lowest (73%). Implications for future drug research are discussed.

The effects of psychiatric comorbidity on response to an HIV prevention intervention.

Drug abusers with psychiatric comorbidity are at high risk for becoming exposed to HIV. To address this compelling public health issue, our randomized HIV prevention study compares the effectiveness of the NIDA standard HIV testing and counseling protocol to a four session, peer-delivered, educational intervention for out-of-treatment cocaine users with and without antisocial personality disorder (ASPD) and major depression. Among the 966 out-of-treatment cocaine users who have completed the 3 month follow-up, all groups, regardless of assignment to standard vs. peer-delivered intervention or psychiatric status, improved significantly in: crack cocaine use, injection drug use, number of IDU sex partners and overall number of sex partners, but not in condom use. Nevertheless, when stratified by psychiatric status, ASPD was associated with significantly less improvement in crack cocaine use (P = 0.04) and with a trend for less improvement in having multiple sex partners and having IDU sex partners (P = 0.06 and 0.08, respectively). ASPD status was not associated with change in injection drug use or condom use. Depression was associated with a trend (P = 0.07) for greater improvement in crack cocaine use but not in any of the other behaviors. When examining the standard and peer intervention groups separately, no consistent differences in the association of psychiatric comorbidity with outcome were discerned between the two groups. We conclude that persons with ASPD and depression respond well to standard HIV prevention interventions, but these psychiatric disorders respectively attenuate and enhance response somewhat. Behavioral interventions tailored for persons with these conditions may be indicated if long-term change in HIV risk behaviors is to be achieved.

Diagnostic concordance of DSM-III-R, DSM-IV, and ICD-10 inhalant use disorders.

The diagnostic concordance of DSM-III-R, DSM-IV, and ICD-10 inhalant use disorders was assessed using the sample of lifetime inhalant users (n=76) participating in the DSM-IV Field Trial for Substance Use Disorders. Substantially smaller proportions of lifetime inhalant users met DSM-IV inhalant abuse or dependence criteria than met comparable DSM-III-R or ICD-10 criteria. DSM-III-R and ICD-10 performed similarly, although DSM-III-R tended to be more inclusive vis-à-vis diagnoses of inhalant dependence. Kappa coefficients indicated a moderate degree of concordance between the three nosologies for inhalant use disorder diagnosis rates. Inclusion of possible withdrawal symptomatology criteria (that are not normally included) in the DSM-IV and ICD-10 criteria sets for inhalant dependence exerted little effect on diagnosis rates.

Subjective reports of withdrawal among cocaine users: recommendations for DSM-IV.

The proposed DSM-IV criteria for substance use disorders have included, as an option, a subtyping for physiologic dependence, characterized by either tolerance or withdrawal. Even if this option is not chosen at this stage of system revision, this weighting scheme justifies wider surveillance of these symptoms, especially for the more newly described cocaine dependence disorder. Wider surveillance of withdrawal is possible with the CIDI Substance Abuse Module (SAM), a WHO/ADAMHA diagnostic interview which covers criteria of substance use disorders according to the DSM-III, III-R, ICD-10 and proposed DSM-IV systems. To aid in this effort, we used the SAM, which includes a master list of all symptoms (n = 16) in the DSM manuals related to withdrawal from any substance to assess withdrawal symptoms from all substances. In this study, we hypothesized that the persons who used opiates with cocaine might misattribute their symptoms to cocaine; thus, we compared the responses of persons who used cocaine and opiates (opiate users) with the responses of persons who used cocaine without opiates (non-opiate users). Data from two St. Louis studies were combined for these analyses, users not in treatment or newly enrolled to drug-free or methadone treatment from a NIDA demonstration project and users selected for the St. Louis DSM-IV Field Trial. Of the 196 persons included from the field trial, 80% reported lifetime cocaine use compared with 91% of the 412 persons from the demonstration project. The symptoms mentioned in the diagnostic manuals were among the most frequently endorsed by both cocaine use groups.(ABSTRACT TRUNCATED AT 250 WORDS)
