Development of the Perception of Opioid Use Survey Instrument

BACKGROUND AND PURPOSE

A new instrument was designed specifically to evaluate nurses' knowledge, attitude, and practice toward patients who use opioids. This study team developed and tested the psychometric properties of the Perception of Opioid Use Survey (POUS) instrument.

METHODS

The instrument was tested among 306 nurses at a 183 bed acute care community hospital, with psychometric evaluation for validity, reliability, and exploratory factor analysis.

RESULTS

Internal consistency results were Cronbach's alpha = .550 for the overall scale and each subscale: Self-Efficacy = .796, Attitudes = .744, Community Impact = .806, and Causative Factors = .763.

CONCLUSIONS

Psychometric testing results support that the POUS is valid, reliable, and significantly correlated with theoretically selected variables.

Implicit Bias in Prenatal Drug Testing

Unfortunately, risk-based testing introduces physician bias into decisionmaking, and can disproportionately target low-income, minority, and immigrant women. Simultaneously, physicians can overlook screening patients who are white and higher income, placing their infants at risk for drug withdrawal and birth defects. Universal screening has been touted by many physicians and providers because it eliminates risk for discriminatory practices, provides a basis for early detection and education of pregnant women, and directs physicians to provide resources for pregnant women to quit drug use during pregnancy.

Barriers and facilitators in antenatal settings to screening and referral of pregnant women who use alcohol or other drugs: A qualitative study of midwives' experience

BACKGROUND

Screening pregnant women for substance use is highly recommended in antenatal care settings. Although midwives provide routine screening for substance use and referral for treatment in pregnancy, little is known about the barriers and facilitators they experience.

AIM

The study explored barriers and facilitators experienced by midwives in antenatal settings to screening and referral of pregnant women who use alcohol or other drugs.

DESIGN/SETTING

A semi-structured interview was adopted to explore barriers and facilitators experienced by midwives in screening and referring pregnant women for alcohol or other drugs specialised services. Eighteen midwives were recruited from urban, regional and rural antenatal settings in Victoria. Interviews were tape recorded and transcribed verbatim. Themes were generated by thematic analysis, the process of identifying patterns within the data.

FINDINGS

Of the seven themes identified under barriers, five could be categorised as "institution and provider-related", namely: (i) lack of validated screening tool, (ii) inadequate support and training, (iii) discomfort in screening, (iv) lack of multidisciplinary team and specialised treatment in regional and rural areas, and (v) workload and limited consultation time. Conversely, two themes could be classified as 'client-related', namely (i) non- or partial-disclosure of substance use, and (ii) reluctance and non-adherence to referrals. All five themes under facilitators were "institution and provider-related." They are (i) a woman-centred philosophy of care, (ii) evidence of harms from substance use on neonates, (iii) experience and training, (iv) continuity of care, and (v) availability of multidisciplinary team and funding.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

To the best of our knowledge, this is the first study of its kind conducted in Victoria. This study not only adds to the limited body of knowledge on barriers experienced by midwives but also identifies facilitators in antenatal settings that promote screening and referral of pregnant women who use substance. Most of the barriers and facilitators are interrelated. Despite midwives' willingness to screen all pregnant women for substance use and provision of referral, they often felt limited in their capacity. Availability and accessibility to validated screening tool(s), in addition to regular, ongoing training for all midwives to maintain clinical competence and provide effective communication are imperative. Availability of a multidisciplinary team, funds and specialised care facilities such as detoxification and mental health services, especially in regional and rural areas, are necessary to effectively support at-risk pregnant women.

Alcohol and drug testing of health professionals following preventable adverse events: a bad idea

Various kinds of alcohol and drug testing, such as preemployment, routine, and for-cause testing, are commonly performed by employers. While healthcare organizations usually require preemployment drug testing, they vary on whether personnel will be subjected to further testing. Recently, a call has gone out for postincident testing among physicians who are involved in serious, preventable events, especially ones leading to a patient's death. This article will offer a number of counterarguments to that proposal and discuss an alternate approach: that health institutions can better improve patient safety and employees' well-being by implementing an organizational policy of "speaking up" when system operators notice work behaviors or environmental factors that threaten harm or peril. The article will conclude with a description of various strategies that facilitate speaking up, and why the practice constitutes a superior alternative to mandatory alcohol and drug testing in the wake of serious, harm-causing medical error.

Under-reporting of drug use among individuals with schizophrenia: prevalence and predictors

BACKGROUND

Illicit drug use is common in individuals with schizophrenia, and it has been suspected that many individuals under-report their use of substances, leading to significant barriers to treatment. This study sought to examine the degree to which individuals with schizophrenia disclose their use of drugs on self-rated assessments, compared to laboratory assays, and to determine the contributors of under-reported drug use in this population.

METHOD

A total of 1042 individuals with schizophrenia who participated in screening/baseline procedures for the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) completed self-rated assessments of substance use and laboratory drug testing. Laboratory tests assayed cannabis, cocaine and methamphetamine use; the procedures included radioimmunoassay (RIA) and urine drug screens.

RESULTS

A significant proportion of participants tested positive for drug use on laboratory measures (n = 397; 38%), and more than half (n = 229; 58%) did not report using these drugs. Logistic regression models confirmed that patients who were most likely to conceal their use tended to be older, and presented with greater neurocognitive deficits. Patients who accurately reported drug use tended to have greater involvement with the criminal justice system. Illness severity and psychopathology were not associated with whether patients disclosed drug use.

CONCLUSIONS

Rates of under-reported drug use are considerable among individuals with schizophrenia when compared to laboratory assays, and the exclusive reliance on self-rated assessments should be used with caution. Patients who under-report their drug use are more likely to manifest neurocognitive deficits, which could be improved by interventions attempting to optimize treatment.

Juridical and ethical peculiarities in doping policy

Criticisms of the ethical justification of antidoping legislation are not uncommon in the literatures of medical ethics, sports ethics and sports medicine. Critics of antidoping point to inconsistencies of principle in the application of legislation and the unjustifiability of ethical postures enshrined in the World Anti-Doping Code, a new version of which came into effect in January 2009. This article explores the arguments concerning the apparent legal peculiarities of antidoping legislation and their ethically salient features in terms of: notions of culpability, liability and guilt; aspects of potential duplication of punishments and the limitations of athlete privacy in antidoping practice and policy. It is noted that tensions still exist between legal and ethical principles and norms that require further critical attention.

Citalopram Combined with Behavioral Therapy Reduces Cocaine Use: A Double-Blind, Placebo-Controlled Trial

Cocaine dependence continues to be a significant problem in the United States, without any approved pharmacotherapy. Promising findings from preclinical research on the effects of cocaine on serotonin lead to examination of selective serotonin reuptake inhibitors (SSRIs) as potential treatments for cocaine dependence with mixed results, possibly due to drug interactions or specifics of concomitant behavioral therapy. The purpose of this study was to examine whether the SSRI citalopram would reduce cocaine positive urines in a 12-week, double-blind placebo-controlled trial. Seventy-six cocaine dependent patients received either citalopram 20 mg per day or placebo along with cognitive behavioral therapy (CBT) and contingency management (CM). Citalopram treated subjects showed a significant reduction in cocaine-positive urines during treatment compared to placebo treated subjects. No differences were noted in retention between the two groups. Side effects reported for citalopram were mild, with none leading to discontinuation of study drug. Results of this study support further examination of citalopram in combination with behavioral therapy as a treatment for cocaine dependence.

Female recidivists speak about their experience in drug court while engaging in appreciative inquiry

Eleven female drug-court participants looked at current and past experiences to assess their program and envision future program innovations. From these women's perspective, the strongest component of drug court was being surrounded by staff dedicated to their progress and recovery. Graduated supervision and accurate drug testing were appreciated rather than resented when the participants were not humiliated and were treated with respect. Wraparound services, resources, and referral; treatment facilities that accepted children; and individualized treatment plans and therapy with offenders who are ex-addicts, and preferably females, allowed for greater involvement and active participation in recovery. Progressing through three phases, acquiring skills, a job, and visitation rights to see their children or regaining custody, increased these women's sense of self-efficacy perception and confidence in their ability to lead a drug-free, meaningful life. Findings show the importance of qualitative criteria in evaluating drug-court participants' progress and the process of recovery.

Stigma, discrimination and the health of illicit drug users

Persons who use illicit drugs are stigmatized in the United States. The conferral of a deviant social status on illicit drug users may serve to discourage use. However, stigmatization may also adversely affect the health of those who use illicit drugs, through exposure to chronic stress such as discrimination and as a barrier to accessing care. We hypothesized that aspects of stigma and discrimination would be associated with mental and physical health among illicit drug users. Using street outreach techniques, 1008 illicit drug users were interviewed about stigma and discrimination related to their drug use, and their health. We measured discrimination related to drug use, alienation, perceived devaluation, and responses to discrimination and stigma. Health measures included mental and physical health measures from the Medical Outcomes Study Short Form-36, depression symptoms from the Center for Epidemiological Studies Depression scale, and a sum of health conditions. In adjusted models, discrimination and alienation were both associated with poorer mental health, and only discrimination was associated with poorer physical health. Angry responses to discrimination and stigma were associated with poorer mental health. The association of stigma and discrimination with poor health among drug users suggests the need for debate on the relative risks and benefits of stigma and discrimination in this context.

An opioid screening instrument: long-term evaluation of the utility of the Pain Medication Questionnaire

The Pain Medication Questionnaire (PMQ) was designed to assess the risk for opioid medication misuse in chronic pain patients. A preliminary study showed a positive relationship between higher PMQ scores and concurrent measures of substance abuse, psychopathology, and physical/life-functioning. Using a larger sample size, the present study sought to replicate these findings, and to expand upon them by examining the relationship between PMQ scores and various treatment outcomes. The PMQ was administered to 271 newly evaluated chronic pain patients who were subsequently re-evaluated immediately post-treatment, as well as six months following discharge. Subgroups were then formed according to the lowest (L-PMQ), middle (M-PMQ), and highest (H-PMQ) one-third of PMQ total scores. It was found that the H-PMQ group was 2.6 times more likely to have a known substance-abuse problem, 3.2 times more likely to request early refills of prescription medication, and 2.3 times more likely to drop out of treatment, as compared to the L-PMQ group. They also had diminished biopsychosocial functioning. In addition, at six months following discharge, patients who completed the program experienced a significant decrease in PMQ scores over time relative to those patients who were unsuccessfully discharged from the program or who dropped out. This study represents the second stage in the development of a psychometrically sound screening tool for measuring risk for opioid medication misuse among chronic pain patients, and findings suggest the long-term utility of the PMQ in identifying patients who are more likely to complete and benefit from a pain management program.

Underreporting of illicit drug use by patients at emergency departments as revealed by two-tiered urinalysis

This study investigates the validity of questionnaire-based self-reports of illicit drug use by comparing with a two-tiered urinalysis among patients at emergency departments. Questions on the use of alcohol and drugs were administered to patients recruited on a continual basis for 2weeks at the emergency department of two hospitals in northern Taiwan. Positive tests of initial urinalysis using fluorescence polarization immunoassay were further confirmed by gas chromatography/mass spectrometry. In a total of 1502 patients interviewed, 632 (42%) also provided a urine sample. Among those with urine samples, the positive rate of urinalysis was 1.4% for amphetamine-type drugs and 1.6% for opiates. Among those with positive urinalysis, a false-negative rate ranged from 66.6% for amphetamines to 70.0% for opiates. Meanwhile, all the self-reported current uses of either amphetamines or opiates were confirmed by urinalysis. The results indicate that the false-negative rates of questionnaire-based, self-reported current use of illicit drug are around two thirds and the false-positive rates are negligible, which might be useful for the calibration of estimates from epidemiological surveys.

Preliminary findings of noncompliance with psychotropic medication and prevalence of methamphetamine intoxication associated with suicide completion

OBJECTIVE

A study of medical examiner records from suicide completers was designed to identify potential precipitating factors in the decision to commit suicide.

METHODS

Forensic data has been collected for a subset of suicide victims in Utah who completed suicide between 1996 and 2002.

RESULTS

Youth suicide completers appear to be undiagnosed for mental illness, or to be noncompliant with psychotropic medications. Along with treatment issues, alcohol and methamphetamine were the most common substances found in the blood and/or urine of suicide completers.

CONCLUSIONS

Accurate diagnosis of mental illness, and improved compliance with psychotropic medications may play a critical role in suicide prevention. The prevalence of methamphetamine in suicide completers is unexpectedly high and requires further investigation.

Methadone and nicotine self-administration in humans: a behavioral economic analysis

RATIONALE

Prior research has revealed inconsistencies in the behavioral relations between nicotine and opiates among methadone-maintained patients.

OBJECTIVES

The current study examined whether the drug reinforcers cigarette puffs and methadone were economic complements or substitutes.

METHODS

Five methadone-maintained, nicotine-dependent participants were trained to self-administer methadone, cigarette puffs, or concurrently available methadone and puffs. Following training, the fixed ratio (FR) value ("price") was increased across sessions (FR 32, 64, 128, 256, and 512), first for methadone and then for puffs. Subsequently, methadone and puffs were concurrently available, and the price of each drug was increased independently, while the price of the alternative (puffs or methadone) remained constant at FR 32.

RESULTS

Demand for methadone and cigarette puffs decreased as a function of increases in methadone and cigarette puff prices, respectively. When methadone and puffs were concurrently available, an increase in methadone's price decreased puff consumption, and demand for methadone was less elastic than when puffs were not concurrently available. An increase in puff price decreased puff and methadone demand, but the elasticity of puff demand was unaffected. The concurrent presence of methadone had no effect on the elasticity of demand for cigarette puffs.

CONCLUSIONS

Methadone and cigarette puffs appear to be asymmetric economic complements.

Adolescent attitudes toward random drug testing in schools

The current research examined students' perceptions of random drug testing for students participating in after-school activities. Results found students were more likely to endorse drug testing at their school if they are already engaged in after-school activities and not currently using drugs and/or alcohol. While middle and high school students' scores fell within the median, most reported if drug testing were implemented in their school they believed it would not deter continued participation in after-school activities. However, if drug testing were a prerequisite for participating in after-school activities, high school students were more apprehensive about getting tested than middle school students. Student respondents were more likely to endorse drug testing, if all members of the school system (i.e., teachers, coaches and staff) participated in drug testing. High school students' believed they had enough knowledge about drug abuse and were less likely to endorse drug testing because they believed it would violate their personal privacy compared to grade school students. Results also differed as a function of gender and self-reported drug and alcohol use.

Identifying the drug seeker: the advanced practice nurse's role in managing prescription drug abuse

PURPOSE

To provide advanced practice nurses (APNs) with a definition of drug-seeking behaviors, to identify the common signs and symptoms of drug-seeking behaviors, to furnish tips for managing interactions with and treatment of the drug-seeking patient, and to describe prescription parameters that will help APNs avoid legal ramifications.

DATA SOURCES

A review of the current scientific and clinical literature regarding interaction with and treatment of patients who abuse prescription drugs.

CONCLUSIONS

A basic understanding of drug-seeking behaviors and adherence to appropriate procedures for prescribing controlled medications are essential for APNs to maintain their safe prescribing habits; carry on with quality, effective care; and continue the advancement of their profession.

IMPLICATIONS FOR PRACTICE

As primary care providers, APNs must be aware of the potential complications resulting from interacting with patients who may be seeking prescription drugs for recreational or illicit use, rather than for legitimate reasons.

Drug test feasibility in a general population household survey

Drug testing was used as an adjunct to a general population household drug use survey administered via audio computer assisted self-interview. Participants, ages 18-40 years residing in Chicago, were recruited to participate in three different biological tests (hair, oral fluid, and urine) presented in random order subsequent to completing an interview. Subjects had the option of participating in zero to three different tests. We examined participation/refusal in tests, reaction to testing requests, as well as variables associated with participation and reaction. Subjects were randomly assigned to a low (US$ 10 per test) or high (US$ 20 per test) incentive condition. Over 90% of the sample participated in at least one test, usually the oral fluid test. Associations between refusal status and two variables, socioeconomic status (SES) and presence of children in the household, provided partial support for the notion that drug test participation parallels the survey response process in general. Incentive level did not directly increase drug test participation. Reporting of recent illicit drug use was associated with participation in only one procedure, hair testing. Type of test offered and individual differences in willingness to be drug tested were important predictors of drug test refusal and subject reaction to testing requests. Compared with urine and hair testing, oral fluid testing had lower refusal rates and was generally more acceptable to respondents in a general population survey. The findings support the feasibility of incorporating multiple drug tests with modest incentives into general population household surveys on drug abuse.

Urine testing for drugs of abuse: a survey of suburban parent-adolescent dyads

BACKGROUND

The American Academy of Pediatrics is opposed to involuntary diagnostic testing for drugs of abuse.

OBJECTIVE

To gather data about attitudes of parents and their teenagers about involuntary drug testing on parental request.

DESIGN

Adolescents and their accompanying parents separately answered a printed survey in the offices of their private pediatrician. The survey posed 2 hypothetical questions about urine testing: (1) Do parents have the right to ask a teenager's physician to order a urine test for drugs of abuse without the teenager's knowledge-if the teenager has falling school grades, an uncooperative attitude, and major untruthfulness? (2) In such a case, should the teenager's physician obtain a urine test for drugs on parental request only, without the teenager's consent?

RESULTS

A total of 393 paired evaluable surveys were collected: 77.6% from Virginia and 22.4% from Ohio. There were no significant differences in answers between the 2 study sites. Of the students, 85.8% had either an A or a B grade point average. Current marijuana use was unusually low in our teenaged respondents. Of the parents surveyed, 81.7% would want a physician to be able to perform a urine test for drugs of abuse for a problematic teenager without the young person's consent. The answers to the 2 questions about urine drug tests had poor kappa coefficients of agreement between teenagers and parents (0.04 and 0.09, respectively). Reanalysis, using the variables of age, grade point average, and frequency of marijuana smoking, showed little difference in agreement scores.

CONCLUSIONS

In the 2 suburban pediatric practices surveyed, parental opinions and expectations were at variance with the American Academy of Pediatrics policy statement on nonconsensual urine drug testing in the presence of clinical problems. Pediatricians need to be conscious of this clinical-ethical dilemma, become familiar with the American Academy of Pediatrics policy on drug testing, and develop their own position and expertise in this area. The dyad method (parent-teenager survey) is novel and improved the methodology of our study. We surveyed middle-class suburban adolescents while previous studies of adolescents surveyed inner-city populations.

The identification and management of the drug impaired doctor

BACKGROUND

Problem drug use occurs within the medical fraternity as it does in other parts of the population. However, doctors have traditionally been discouraged from admitting vulnerability and frequently fail to recognise or respond to early signs of problem alcohol and drug use.

OBJECTIVE

This article aims to identify sequential strategies to assist the doctor to detect and intervene early when problem drug use arises in themselves or a colleague.

DISCUSSION

Where treatment and monitoring is instituted early in problem drug use, outcomes are typically positive while late acknowledgment commonly results in sanctions for the impaired practitioner and greater risk to patients. Medical boards in Australia have developed supportive mechanisms for doctors to facilitate early management. Procedures are aimed at maintaining or restoring ability to work while maintaining public confidence.

Hospitalization of patients with cocaine and amphetamine use disorders from a psychiatric emergency service

OBJECTIVES

Among the illicit stimulants, cocaine and amphetamines are the most widely abused. Although these drugs have similar psychoactive properties and routes of administration, their duration of action and mechanism of action are different, as are the psychiatric problems that accompany their use. The authors explored whether these differences and results of urine drug testing were associated with differences in use of psychiatric inpatient services.

METHODS

The records of 2,357 patients admitted to a large county psychiatric emergency service were examined to determine whether patients admitted for amphetamine-related or cocaine-related disorders differed in rates of transfer to an inpatient psychiatric ward or in length of stay on the ward after transfer. The authors also examined whether positive or negative results of urine drug screens predicted transfer or length of stay.

RESULTS

Patients with amphetamine-related disorders were more than a third more likely than patients with cocaine-related disorders to be transferred to the inpatient ward. Patients with negative urine screens were a third more likely than those with positive screens to be transferred and stayed slightly longer on the ward after transfer. Patients with cocaine-related disorders stayed slightly longer on the ward than patients with amphetamine-related disorders.

CONCLUSIONS

Patients with amphetamine-related disorders have higher rates of psychiatric hospitalization than patients with cocaine-related disorders. Diagnostic uncertainty and other factors may also influence transfer rates and subsequent length of stay.

The RAFFT as a screening tool for adult substance use disorders

The purpose of this study was to evaluate the specificity and sensitivity of the RAFFT, a brief screening tool, in adult patients with substance use disorders (SUD) when presenting to a psychiatric emergency room. A total of 215 patients were evaluated with the RAFFT, the CAGE, the Mini International Neuropsychiatric Interview, and urine drug screens. The RAFFT performed well in adults with SUD and was not influenced by factors such as gender, race, socioeconomic status, or the co-existence of psychiatric disorders. In alcohol use disorders, the CAGE performed better than the RAFFT, due to the lower specificity (or more false positive answers) of the latter.

A comparison of the OnTrak Testcup-5 to laboratory urinalysis among arrestees

Research studies that collect urine specimens to measure recent drug use have traditionally sent the specimens to laboratories for analysis. A new method of urinalysis-instant urine testing-may offer a quicker, equally accurate alternative to laboratory assays. To date, however, no studies have explored the efficacy of instant urine technology with individuals under criminal justice supervision. To address this limitation, the authors administered a single instant urine test-the OnTrak Testcup-5-to 136 adult male arrestees surveyed through Maryland's Substance Abuse Need for Treatment among Arrestees (SANTA) study. The specimens were subsequently shipped to an independent laboratory for reanalysis. Analyses indicate high agreement between the two techniques for marijuana, cocaine, and heroin. Potential uses for the OnTrak Testcup-5 are discussed.

Are drunk-driving offenders referred for screening accurately reporting their drug use?

Several studies report that a substantial percentage of offenders arrested for impaired driving test positive for drugs of abuse besides alcohol. Current guidelines recommend screening offenders for both alcohol and other drug use, yet little is known about the accuracy of self-reports of drug use in this population. We compared drug abuse and dependence DSM-III-R diagnoses from an initial, court-ordered screening evaluation of 583 female and 495 male convicted drunk-driving offenders with diagnoses obtained via a voluntary, non-coerced interview 5 years later. At initial screening, fewer than 6% of offenders were diagnosed with drug abuse or dependence. Among offenders who did not receive an initial drug diagnosis, 28% subsequently reported having experienced drug use problems consistent with a retrospective diagnosis of drug abuse or dependence by the age at which they were screened. Half of those with a retrospective diagnosis of drug dependence reported their initial screening responses were "very accurate". We conclude that, although many drunk-driving offenders undergoing screening have diagnosable drug problems, a high proportion under-report their drug use. We suggest that certain modifications to screening procedures, such as urine drug screening, reducing barriers to treatment, and training counselors in motivational interviewing techniques, may increase accurate identification of drug use problems in this population.

Alcohol-related discussions during general medicine appointments of male VA patients who screen positive for at-risk drinking

OBJECTIVE

This study describes primary care discussions with patients who screened positive for at-risk drinking. In addition, discussions about alcohol use from 2 clinic firms, one with a provider-prompting intervention, are compared.

DESIGN

Cross-sectional analyses of audiotaped appointments collected over 6 months.

PARTICIPANTS AND SETTING

Male patients in a VA general medicine clinic were eligible if they screened positive for at-risk drinking and had a general medicine appointment with a consenting provider during the study period. Participating patients ( N = 47) and providers ( N = 17) were enrolled in 1 of 2 firms in the clinic (Intervention or Control) and were blinded to the study focus.

INTERVENTION

Intervention providers received patient-specific results of positive alcohol-screening tests at each visit.

MEASURES AND MAIN RESULTS

Of 68 visits taped, 39 (57.4%) included any mention of alcohol. Patient and provider utterances during discussions about alcohol use were coded using Motivational Interviewing Skills Codes. Providers contributed 58% of utterances during alcohol-related discussions with most coded as questions (24%), information giving (23%), or facilitation (34%). Advice, reflective listening, and supportive or affirming statements occurred infrequently (5%, 3%, and 5%, of provider utterances respectively). Providers offered alcohol-related advice during 21% of visits. Sixteen percent of patient utterances reflected "resistance" to change and 12% reflected readiness to change. On average, Intervention providers were more likely to discuss alcohol use than Control providers (82.4% vs 39.6% of visits; P =.026).

CONCLUSIONS

During discussions about alcohol, general medicine providers asked questions and offered information, but usually did not give explicit alcohol-related advice. Discussions about alcohol occurred more often when providers were prompted.

The validity of adult arrestee self-reports of crack cocaine use

Despite the many problems associated with crack use, little validated empirical evidence about the prevalence of crack cocaine exists. Researchers that track crack cocaine use have relied on self-reports to differentiate crack and powder cocaine. Prior research suggests that the accuracy of self-reports for the use of a variety of illicit substances is relatively low. To examine the validity of self-reports of crack use, this article employs a newly developed technology to detect specifically the presence of markers of crack cocaine in urine specimens. With a sample of 2327 arrestees from six cities that participate in the Arrestee Drug Abuse Monitoring (ADAM) Program, both face-to-face interview and urinalysis data were examined. Using a positive urinalysis result as the validity standard, we assessed the extent to which arrestees underreport crack cocaine use as compared to the use of marijuana, opiates,and methamphetamine. Logistic regression models were also de veloped to predict the factors that relate to underreporting. The results showed a considerable amount of underreporting for all the drug measures. In most cases, only about half the people who had a positive urinalysis test for drugs admitted using drugs. Overall, the least amount of underreporting occurred for the use of marijuana (63.6% told the "truth"), followed by methamphetamine (56.1% told the truth), crack (48.2% told the truth), and opiate (45.9% told the truth). Female crack users, as compared to male crack users, were more likely to admit using crack. Black arrestees were more likely to admit using crack than white or Hispanic arrestees. Arrestees with a history of prior drug treatment or a prior arrest, as compared to those without such histories, were more likely to admit using crack. The older the arrestee was, the more likely the arrestee would admit using crack. The more money an arrestee spent on drugs, the more likely the arrestee would admit using crack. Differences in underreporting were also observed across the six cities in this study. The implications of these findings for the monitoring of crack use are discussed.

Concurrent substance use and outcome in combined behavioral and naltrexone therapy for opiate dependence

The effect of concurrent nonopiate drug use on outcome of treatment for opiate dependence.

METHOD

Forty-seven opiate-dependent patients received a 6-month course of outpatient treatment with naltrexone and cognitive-behavioral therapy (behavioral naltrexone therapy, BNT) at a university-based research clinic. Opiate-negative urines and naltrexone ingestion were rewarded with monetary vouchers. Abstinence from other drugs was encouraged verbally, but no contingencies were placed on nonopiate drug use. The proportions of all urines (collected twice weekly) positive for cocaine, cannabis, and benzodiazepines over the course of treatment were evaluated as predictors of outcome of opiate dependence treatment, as measured by proportion of opiate-positive urines, days retained in treatment, and proportion of naltrexone doses taken, using Pearson product moment correlations and one-way analysis of variance (ANOVA).

RESULTS

The majority of patients (78%) used a nonopiate drug at least once during the trial. There were no significant correlations between concurrent drug use measures and opiate dependence treatment outcomes, indicating no simple linear relationship between these measures. However, when concurrent drug use was trichotomized into abstinent, intermittent, and heavy use groups, groups with intermittent use had superior outcome compared to both abstinent and heavy use groups in several contrasts.

CONCLUSIONS

Intermittent use of nonopiate drugs is common during outpatient treatment for opiate dependence and may be a favorable prognostic indicator. This may support a "harm reduction" approach as opposed to a strict abstinence-oriented approach. Further research is needed to identify the optimal therapeutic stance toward other drug use during treatment for opiate dependence.

Antisocial behavioral syndromes and return to drug use following residential relapse prevention/health education treatment

This study compared residential addiction treatment clients meeting full DSM-III-R criteria for antisocial personality disorder (ASPD) with those reporting syndromal levels of antisocial behavior only in adulthood (AABS) on time to and severity of first posttreatment drug use. Antisocial syndrome and selected other mental disorders were assessed using the Diagnostic Interview Schedule, Revised for DSM-III-R, and validity of self-reported posttreatment drug behavior was measured against results of hair analysis. Among subjects followed within 180 days after treatment exit, individuals with ASPD were at modestly increased risk of a first lapse episode compared to those with AABS. However, the two groups did not differ in severity of lapse. Participants with ASPD demonstrated poorer agreement between self-reported posttreatment drug behavior and hair data. These results add to the evidence suggesting that the DSM requirement for childhood onset in ASPD may be clinically important among substance abusers in identifying a severely antisocial and chronically addicted group at elevated risk for early posttreatment recidivism. Our findings support the importance of careful classification of antisocial syndromes among substance abusers and the identification of characteristics of these syndromes that underlie clients' risks for posttreatment return to drug use to provide optimally individualized treatment planning.

A comparison of saliva testing to urinalysis in an arrestee population

Past studies have concluded that individuals under criminal justice supervision often underreport their recent use of illicit drugs. To address this underreporting, objective biological measures, such as urine, saliva, and hair testing, have been used to gain better estimates of illegal drug use. While urinalysis is generally recognized as the reference standard, a method recently introduced in nonlaboratory settings for ascertaining drug use-saliva testing-may offer an alternative to urinalysis. To date, however, no studies have compared saliva testing to urinalysis among criminal justice populations. In the current study, urine and saliva specimens were collected from 114 adult arrestees interviewed as part of Maryland's Substance Abuse Need for Treatment among Arrestees (SANTA) project. With urinalysis as the reference standard, analysis of the saliva test results indicated sensitivity of 100% and specificity of 99% for cocaine and sensitivity of 88% and specificity of 100% for heroin. For marijuana, however, the saliva results indicated a sensitivity of only 5%. Anecdotal reports from the field suggest that saliva may have some advantages over urine because of the ease of collection, invulnerability to adulteration, and minimal personal invasiveness. These findings suggest that a more comprehensive study to evaluate the efficacy of saliva testing in field research may be warranted.

Urinalysis drug testing within a civilian pilot training program: did attitudes change during the 1990's?

BACKGROUND

Attitudes toward fairness and effectiveness of mandatory drug testing vary within pilot populations (4,8) as well as other populations (3). This descriptive-correlational study examined civilian student pilots' attitudes toward urinalysis (UA) drug testing over a 10-yr period and the pilots' opinions regarding effectiveness, adequacy, and fairness of the testing as a deterrent for substance abuse among pilots.

METHODS

A sample of three different groups of civilian aviation students (n = 314), consisted of 103 pilots studied prior to implementing a mandatory drug testing program, 113 pilots studied 1 yr after implementing a mandatory drug testing program, and 98 pilots studied 6 yr into a mandatory drug testing program. A 14-item questionnaire (alpha = 0.74), indicating degrees of agreement, was completed by the student pilots who were enrolled in a large civilian pilot training program.

RESULTS

There were no significant differences among the study pilots' feelings related to anxiety of drug testing when comparing non-mandatory and mandatory groups over time. The pilots continue to believe that alcohol use by pilots within this civilian piloting training program has decreased since testing was mandated and that drug use also showed a significant decrease (p = 0.01), although not as significant (p = 0.0001) as the decrease in alcohol use.

CONCLUSION

The study showed that alcohol and drug testing is more generally accepted by the pilots in the study as the decade of the 1990s came to a close.

Selection of screening items for alcohol abuse and alcohol dependence among Mexicans and Mexican Americans in the emergency department

OBJECTIVE

This article reports on the selection of screening items to detect Mexican or Mexican-American patients in the emergency department (ED) who have alcohol problems and could benefit from an intervention or a referral for treatment. Items are tested against the Rapid Alcohol Problems Screen (RAPS), which has been optimized from standard screening instruments and has outperformed these instruments.

METHOD

The performance of individual items from standard screening instruments (CAGE, TWEAK, AUDIT, TRAUMA and BMAST) against International Classification of Diseases, Tenth Revision and Diagnostic and Statistical Manual, Fourth Revision criteria for alcohol abuse and dependence was evaluated in a merged probability sample (N = 869; 72% men) of 537 ED patients from three hospitals in Pachuca, Mexico, and 332 Mexican-American ED patients in Santa Clara County, CA. Logistic regression and tree-classification models were used for item selection.

RESULTS

We found a prevalence of 15% for alcohol dependence and a prevalence of 28% for alcohol abuse or dependence in the merged sample. The RAPS items did not perform as well in terms of sensitivity (93%) as the optimal five items identified in these analyses (sensitivity = 98%) for alcohol dependence, but did demonstrate better specificity (79%) than the optimal five items (65%), which is an important consideration in a time of cost containment. Both sets of items showed better sensitivity and positive predictive value but similar Receiver Operating Characteristic values for respondents in the high acculturation group compared to those at other levels of acculturation. Differences in positive predictive value across all subgroups tended to increase at increased cutpoints, especially for the RAPS.

CONCLUSIONS

These analyses suggest that the RAPS performs favorably compared to those items optimized, in this sample of Hispanic ED patients. Based on comparative item performance in these analyses, the RAPS may hold promise as a useful tool for screening for alcohol dependence, but requires further evaluation as a stand-alone instrument in comparison with other standard screening instruments.

Validity of the CAGE questionnaire in an American Indian population

OBJECTIVE

This study evaluated the performance of the CAGE questionnaire (a set of four questions about alcoholism) in an American Indian population.

METHOD

We analyzed data from a cross-sectional study of 275 individuals (179 women) aged 21 years or older. Alcohol dependence was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised (DSM-III-R), based on a detailed psychiatric interview using the Schedule for Affective Disorders and Schizophrenia-Lifetime Version. Accuracy of the CAGE questionnaire was quantified as sensitivity, specificity, likelihood ratios and the area under receiver operating characteristics (ROC) curves, using the DSM-III-R diagnosis as the reference.

RESULTS

Of participants interviewed, 85% of men and 53% of women had a diagnosis of alcohol dependence by DSM-III-R. A CAGE score of > or = 2 had a sensitivity and specificity of 68% and 93%, respectively, in men and 62% and 79% in women, for the diagnosis of alcohol dependence. CAGE scores of 0, 1 and > or = 2 were associated with likelihood ratios of 0.3, 0.3 and 9.5, respectively, in men and 0.4, 0.7 and 1.5 in women. The area under the ROC curve was 81% for men and 75% for women.

CONCLUSIONS

These findings suggest that the CAGE questionnaire is a valid screening method, in this population, for identifying people likely to have alcohol dependence.

Effects of urine testing frequency on outcome in a methadone take-home contingency program

We examined the effects of urine testing frequency on treatment outcome in a contingent methadone take-home program. Study patients who submitted<80% opiate and/or cocaine positive urines during a 5-week baseline received 60 mg methadone throughout the study, submitted urine samples on Monday, Wednesday, and Friday, and were randomized into one of three take-home incentive conditions. Study patients could receive three take-home doses per week if one urine sample randomly selected each week (Weekly; n=16) or each month (Monthly; n=18) was negative for opiates and cocaine. Take-homes for Random Drawing control patients (n=19) were determined weekly independent of urine test results. Subjects in the Weekly group showed an immediate increase from baseline in percentage of drug-free urines; those in the Monthly group showed a gradual increase over the first 3 months; and those in Random Drawings showed a decline in percentage of drug-free urines over time. The percentage of patients with sustained (8 or more weeks) opiate and cocaine abstinence was 56.6, 38.9 and 10.5% for Weekly, Monthly and Random Drawing groups, respectively (P<0.002). These results confirm that methadone take-homes contingent on drug-free urines prevent a decline in treatment performance over time and suggest that abstinence can be sustained with urine testing conducted as infrequently as once a month.

Results of a baseline urine test predict levels of cocaine use during treatment

Sixty-one cocaine dependent outpatients submitted a single urine sample at least 1 week prior to entry into a 4-week treatment study. Participants were then expected to provide three urine samples per week during the month of treatment. The 61 patients studied here all completed treatment and provided an average of more than 11 of 12 scheduled urine samples. Participants who submitted a cocaine-positive sample prior to treatment provided more positive urine samples during the 4-week trial, were less likely to be completely abstinent during the month, and took longer to reach an initial abstinence criterion of three consecutive cocaine-free urines. Thus, a single pretreatment urine test represents a powerful predictor of subsequent cocaine use. The results suggest that future randomized trials stratify group assignment based on the results of a baseline urine test.

Reinforcing compliance with non-drug-related activities

Contingency management (CM) procedures, that provide incentives for specific behaviors, are efficacious in treating substance use disorders. Typically, CM interventions reinforce submission of urine specimens negative for the targeted drug(s) of abuse, but other behaviors can be reinforced as well, such as compliance with non-drug-related activities. This article describes 1,059 activities chosen by 46 subjects participating in one of two CM studies. The most frequently chosen activities were related to recreational activities (going to movies, library, or church) and sobriety (attending Alcoholics Anonymous meetings, completing worksheets). Over 95% of subjects participated in at least one of these types of activities, and together they accounted for over 70% of the activities selected. Over half the subjects participated in at least one activity related to employment, health, family, and personal improvement, such as applying for a job, attending a medical appointment, taking their child to an event, or creating weekly to-do lists. A detailed description of activity selection and verification procedures may assist in developing consistent approaches across treatment settings, and future research may evaluate further the efficacy of this contingency management approach in treating substance abusers.

Reinforcement-based outpatient treatment for opiate and cocaine abusers

A reinforcement-based intensive outpatient treatment was delivered to 37 recently detoxified, inner city, heroin and/or cocaine abusers who did not want methadone treatment. Attendance was scheduled and urine collected daily for the first 2 weeks, four times weekly for the next 2 weeks, and then thrice weekly for the final 8 weeks. As attendance incentives, patients received transportation assistance (bus tokens), and $28-$30 per week in vouchers to be spent on activities/items chosen and agreed upon with their counselor. As abstinence incentives, patients received weekend supported recreational activities, lunches, $42-$45 per week in vouchers, and rent or utilities payment ($150 over 4 weeks). Total potential earnings was $1,435 per patient; actual mean earnings was $583. Forty-three percent (n=16) completed 10 or more weeks of treatment. These 16 long-stay patients submitted 92% (SD=19) opiate- and cocaine-negative urines during their enrollment compared with 56% (SD=42) drug-negative urines submitted by 21 drop-outs, F(1,35)=9.99, p=0.003. Overall, 32% of clients became employed during their treatment episode; 94% of long-stay patients were employed at the end of their treatment episode. Patients who were drug-positive at intake were highly likely to drop out. Treatment outcomes compare favorably with those reported in the literature for outpatient nonmethadone treatment of opiate and cocaine abusers. Continued evaluation of this new treatment appears warranted.

Comparison of patient self-reports and urinalysis results obtained under naturalistic methadone treatment conditions

This study examined under naturalistic assessment conditions the validity of self-reported opiate and cocaine use among 175 veterans enrolled in methadone treatment, and factors related to self-report validity, such as stage in treatment and drug of abuse. Veterans were interviewed by clinical staff about past 30-day drug use with the addiction severity index (ASI), and urinalysis results were obtained for the same 30-day interval assessed with the ASI. Analysis revealed that urinalysis generally produced higher rates of substance use than patient self-report, and with the exception of reported opiate use among new patients presenting for treatment, validity of patient self-reported drug use generally was poor with patients under-reporting both opiate and cocaine use. The findings are in marked contrast to those obtained in other studies in which participants are ensured confidentiality regarding their self-reports. Further, the results raise questions about the utility of self-report measures of substance use to assess patient progress or methadone program performance.

Broad beneficial effects of cocaine abstinence reinforcement among methadone patients

Escalating reinforcement for sustained abstinence has been effective in treating cocaine abuse. Under this schedule, patients receive vouchers for cocaine-free urine samples; vouchers have monetary values that increase with the number of consecutive cocaine-free urine samples. Cocaine-abusing methadone patients were randomly assigned to receive vouchers for 12 weeks under (a) an escalating schedule (n = 20), (b) an escalating schedule with start-up bonuses (n = 20), or (c) a noncontingent schedule (n = 19). Start-up bonuses were designed to provide added reinforcement for initiating abstinence; however, they did not improve outcomes. Both contingent interventions significantly increased cocaine abstinence. In addition, the contingent interventions increased abstinence from opiates and decreased reports of cocaine craving. These results replicate the efficacy of cocaine abstinence reinforcement and show that it can have broad beneficial effects.

Schedule of voucher delivery influences initiation of cocaine abstinence

This study examined whether voucher delivery arrangements affect treatment outcome. First, 90 cocaine-dependent adults were randomly assigned to behavioral counseling or counseling plus vouchers for cocaine-free urine samples. The value of each voucher was low at the beginning but increased as the patient progressed (Voucher Schedule 1). Voucher Schedule 1 produced no improvements relative to counseling only. Next, 23 patients received vouchers on either Voucher Schedule 1 or Voucher Schedule 2. Voucher Schedule 2 began with high voucher values, but requirements for earning vouchers increased as the patient progressed. Average durations of cocaine abstinence were 6.9 weeks on Voucher Schedule 2 versus 2.0 weeks on Voucher Schedule 1 (p = .02). This confirms that vouchers can assist in initiating abstinence and that voucher delivery arrangements are critical.

Attitudes toward urinalysis drug testing within a civilian pilot training program

BACKGROUND

This descriptive-correlational study examined civilian student pilots' attitudes toward urinalysis (UA) drug testing and the pilots' opinions regarding effectiveness, adequacy, and fairness of the method as a deterrent for substance abuse among pilots.

HYPOTHESIS

There will be significant differences among attitudes of professional aviation student pilots in mandatory and nonmandatory UA drug tested sections of a flight program when considering the pilots' flight hours, ages, gender, anxiety produced by UA drug testing, opinions on drug and alcohol abuse by pilots on the flight schedule, and their attitudes toward the testing process.

METHODS

A Likert-scaled questionnaire was completed by the student pilots who were enrolled in mandatory and nonmandatory UA drug tested class sections within a large civilian aviation flight program.

RESULTS

Pilots felt mandatory UA testing was less anxiety-producing (t = 2.25, p < 0.05) than the students in nonmandatory tested flight classes. The pilots in nonmandatory tested sections felt more strongly (t = 2.55, p < 0.01) that drug use existed among pilots on the flight schedule than mandatorily tested pilots. Significant intercorrelations (p < 0.05) emerged among the variables age, gender, flying hours, randomization of UA testing, and attitudes toward the UA testing process and its' effectiveness.

CONCLUSIONS

Based on the results, mandatory UA drug testing appeared to decrease substance abuse among pilots on the flight schedule.

Screening for psychiatric disorders in medical patients: a feasibility and patient acceptance study

This study examines whether medical patients were bothered or upset by being asked to complete a questionnaire about emotional and substance use problems, and whether a newly developed, brief questionnaire that screens for several psychiatric disorders (the SCREENER) was easy for patients to complete. A consecutive series of outpatients attending the General Medical Clinic at the Philadelphia Veterans Affair Medical Center (VAMC) was approached to ask their participation in a research study requiring the completion of a brief questionnaire about their emotions, moods, thoughts, and behaviors, and a second questionnaire that asked their opinion about the first measure. Only 3.1% of the patients indicated that the questions were difficult to answer, whereas 84.6% found the questions easy or very easy to answer. Between 80% to 90% of the patients were not embarrassed, upset, annoyed, or uncomfortable by answering the questions. Individuals with a history of psychiatric treatment and poorer current mental health were the most likely to have a negative reaction to the questionnaire. Thus, the medical patients in this study reacted favorably to the completion of a broad-based questionnaire about emotional problems. The questions were judged easy to answer and rarely aroused significant negative affect.

Can you trust patient self-reports of drug use during treatment?

This study compared two frequently used measures of drug use, urine testing and self-report in a sample of subjects currently enrolled in methadone treatment for a minimum of six months. A comparison between the percentage of positive opiate urine screens and subjects' self-reported opiate use indicated that more patients self-reported opiate use (80%) than had been detected by urinalysis (57%). Similar results were found for cocaine use. We present arguments that a more inclusive method of measuring drug use during treatment should include the combination of both urinalysis and self-reports.

Predictors of outcome in methadone programs: effect of HIV counseling and testing

OBJECTIVE

To identify predictors of treatment outcomes in methadone maintenance programs and to determine whether HIV counseling and testing influenced these outcomes.

DESIGN

Retrospective record review.

SETTING

Four methadone maintenance programs in four cities in Connecticut, USA.

PARTICIPANTS

Five hundred and ninety-four clients, who began treatment over an 18-month period and for whom records were available, took part.

INTERVENTIONS

HIV counseling and testing.

MAIN OUTCOME MEASURES

Risk of treatment discontinuation and persistent in-treatment illicit drug use.

RESULTS

The most important predictor of treatment discontinuation and of persistent in-treatment illicit drug use was self-reported pretreatment cocaine use. After controlling for this and demographic risk factors, clients who received initial HIV counseling, when compared with clients who did not, had a similar 12-month discontinuation risk (54% vs 59%; P = 0.08) but were less likely to show persistent illicit drug use (46% vs 53%; P = 0.01). Among counseled entrants who were tested for HIV antibodies, those receiving positive results had a 12-month discontinuation risk similar to those receiving negative results (50% vs 52%), but more often showed persistent illicit drug use (57% vs 44%), although this difference may have been due to chance (P = 0.28). The majority of clients who discontinued treatment did so because they were discharged for noncompliance with clinic rules, usually for failing to pay fees.

CONCLUSIONS

HIV counseling and testing do not have a substantial adverse effect on methadone treatment outcomes. In the clinics under study, failure to pay clinic fees was an important factor contributing to discontinuation of treatment.

Testing the abstinence violation effect construct with marijuana cessation

It has been proposed that internal, stable, and global attributions for the cause of a lapse following a period of abstinence and concomitant feelings of guilt and loss of control increased the probability of a return to regular substance use. The Abstinence Violation Effect (AVE) hypotheses were tested in a sample of 75 adult marijuana users who reported a lapse into marijuana use following completion of either a relapse prevention (RP) or social support group treatment aimed at abstinence. Results showed that more internal, stable, and global attributions for the cause of the lapse and perceived loss of control were related significantly to concurrently reported relapse. Further, internal and global attributions predicted marijuana use during the subsequent 6 months. Results are discussed in terms of support for the AVE construct, treatment implications, and the failure of the RP treatment to modify reactions to a lapse.

Alcohol and cocaine abusers 6 months after traditional treatment: do they fare as well as problem drinkers?

Problem drinkers (N = 49) and individuals presenting with both alcohol and cocaine problems (N = 51) admitted to a traditional 28-day alcoholism treatment milieu were compared on their psychosocial, psychological, neuropsychological functioning and substance abuse at admission as well as at six months posttreatment follow-up. On admission, alcohol and cocaine patients were younger, more likely to live alone or with their family of origin, to report having started using alcohol at an earlier age, to have fewer alcohol-related problems and to have fewer years of but more diversity in their substance abuse than the alcohol-only patients. Otherwise both groups were more similar than different on psychosocial, psychological and neuropsychological dimensions. At six-months posttreatment, both groups showed similar improvement on most dimensions of functioning measured. However, a significantly greater proportion of the alcohol and cocaine abusers admitted to having relapsed in the previous six months, reported significantly fewer average days of abstinence than the alcohol group since terminating treatment, and were more likely to present urine specimens indicative of recent substance abuse at the six-month follow-up interview. Thus, traditional approaches to alcoholism treatment may be less effective in establishing abstinence for individuals with both alcohol and cocaine problems. Adaptations to treatment to reduce the risk for relapse faced by alcohol and cocaine abusers in such milieu are discussed.

Validity of patients' self-reported drug use as a function of treatment status

Recent reviews conclude that there is some evidence that drug abusers' self-reports are reliable and valid. However, there are wide variations among studies depending upon the samples and procedures used to obtain the data. The current study was conducted to extend the findings in this area. An examination of the intake interviews and same day urinalyses on 150 patients enrolling for outpatient opioid detoxification or maintenance revealed a fairly high agreement between drug use self-reports and urinalyses. A second study (N = 70) looking at the validity of self-reported drug use at intake and at 4 weeks follow-up revealed some noticeable changes in validity measures, suggesting that contingencies on positive urine results influence self reported drug use of addicts.
