Attention deficit hyperactivity disorder and treatment outcome in opioid abusers entering treatment.

Van L. King; Robert K. Brooner; Michael Kidorf; Kenneth B. Stoller; Allan F. Mirsky

Symptoms of DSM-IV attention-deficit hyperactivity disorder (ADHD) were determined in patients entering methadone maintenance treatment. The relationship of ADHD to psychiatric and substance abuse comorbidity, attention testing, and treatment outcome was analyzed; 19% of patients had a history of ADHD, and 88% of these had current symptoms. Continuous Performance Testing indicated poorer attention in patients with ADHD. The only substance use disorder more common in the ADHD group was clonidine. There was significantly more current axis I, dysthymic disorder, anxiety disorder (including social phobia), and antisocial personality disorder in the ADHD patients. There was no difference between groups at the 1-year follow-up for illicit drug use, treatment retention, or treatment performance. The ADHD diagnosis did not convey significant prognostic implications for methadone maintenance treatment. A strong psychiatric assessment and treatment focus in the treatment program may help to explain the good treatment outcome.

Enhanced schedules of counseling can improve response to routine opioid-agonist treatment, although it is associated with increased time demands that enhance patient resistance and nonadherence. Internet-based counseling can reduce these concerns by allowing patients to participate from home. This study assesses treatment satisfaction and response to Internet-based (CRC Health Groups e-Getgoing) group counseling for partial responders to methadone maintenance treatment. Patients testing positive for an illicit substance (n = 37) were randomly assigned to e-Getgoing or onsite group counseling and followed for 6 weeks. Patients in both conditions responded favorably to intensified treatment by achieving at least 2 consecutive weeks of abstinence and 100% attendance to return to less-intensive care (e-Getgoing: 70% vs. routine: 71%, ns). Treatment satisfaction was good and comparable across conditions. E-Getgoing patients expressed a preference for the Internet-based service, reporting convenience and increased confidentiality as major reasons. Integrating Internet-based group counseling with on-site treatment services could help expand the continuum of care in methadone maintenance clinics.

Influence of psychiatric comorbidity on HIV risk behaviors: changes during drug abuse treatment.

Van L. King; Michael Kidorf; Kenneth B. Stoller; Robert K. Brooner

Abstract This study evaluated whether psychiatric comorbidity is related to change in HIV high risk behaviors during outpatient drug abuse treatment. Participants were opioid abusers entering methadone treatment. Psychiatric and substance use diagnoses were determined at intake. Information on HIV high risk drug use and sexual behaviors, psychosocial functioning, and urine toxicology was assessed at intake and at month six. Subjects were divided into those with versus without a lifetime comorbid non-substance use psychiatric disorder. The comor-bid group reported more injection equipment sharing, lower rates of condom use, and higher rates of alcohol use at intake and follow-up. Overall injection drug use behavior decreased over the follow-up period for both groups, however. Methadone treatment had a beneficial effect on HIV risk behaviors, and though some risk behaviors improved significantly for both groups, comorbid subjects continued to have higher rates of HIV risk factors than noncomorbid subjects.

Increasing employment of opioid dependent outpatients: an intensive behavioral intervention

Michael Kidorf; Johanna R Hollander; Van L. King; Robert K. Brooner

The impact of a new, mandatory employment requirement in a community-based methadone treatment program was evaluated. All patients who had been in the methadone substitution program for at least 1 year but who were not currently employed (n = 36) were required to enhance their treatment with 20 h of employment (paid or volunteer). Patients with significant psychiatric or medical disabilities were excluded from the routine treatment requirement. Patients were informed by counseling staff that they had 2 months to secure employment. Those who did not accomplish the goal within that time period were transferred to more intensive weekly counseling (i.e. up to 8 h/week) for 10 weeks, with the enhanced counseling focusing primarily on resistance to the employment goal. Patients who remained resistant to the treatment plan were eventually started on a 21 day methadone taper until employment was verified. Seventy-five percent of the patients secured employment and maintained the position for at least 1 month. Positions were found in an average of 60 days. Most patients (78%) continued working throughout the 6-month follow-up. Those who failed to find work or maintain employment engaged in more illicit drug use. These results demonstrate that behavioral contingencies can motivate many methadone maintenance patients to obtain verified employment in the community.

Influence of antisocial personality subtypes on drug abuse treatment response.

Van L. King; Michael Kidorf; Kenneth B. Stoller; James A. Carter; Robert K. Brooner

This methodological study examined the impact of antisocial personality disorder (APD) and other psychiatric comorbidity on drug use and treatment retention in 513 new admissions to methadone maintenance treatment. Patients were classified into one of four groups: APD ONLY, APD plus other psychiatric disorder (APD MIXED), other psychiatric disorder, and no psychiatric disorder. Patients completed research assessments and were then followed for 1 year of treatment. Patients with APD had longer histories of heroin and cocaine use than non-APD patients and were more likely to meet criteria for cocaine dependence. Distinct clinical profiles emerged that differentiated APD ONLY from APD MIXED. APD ONLY patients exhibited higher rates of cocaine and heroin use, whereas those with APD MIXED exhibited higher rates of benzodiazepine use. Self-report measures supported urinalysis results, but group differences did not affect treatment retention. These differences in clinical profiles should be considered when evaluating treatment performance in substance abusers with APD.

Predictive validity of cocaine, sedative, and alcohol dependence diagnoses

Michael Kidorf; Robert K. Brooner; Van L. King; Kenneth B. Stoller; Jennifer Wertz

This study examined the predictive validity of Structured Clinical Interview for DSM-III-R (Spitzer, Williams, Gibbon, & First, 1990) based substance dependence diagnoses (i.e., cocaine, sedative, and alcohol) for 518 opioid-dependent outpatients entering methadone maintenance. Patients were followed over 1 year of treatment, which involved daily methadone substitution supplemented by individual and group counseling. Urine specimens were tested randomly 1-4 times per month. Patients diagnosed with current cocaine, sedative, or alcohol dependence were more likely to use these drugs than were patients with past only or no dependence syndrome. Current cocaine dependence predicted early treatment dropout. The results demonstrate the predictive and discriminant validity of several substance dependence diagnoses common among patients in substance abuse or other psychiatric treatment settings.

The present study evaluated the relationship between diagnoses of cocaine and sedative dependence and drug use early in treatment among opioid-dependent patients in methadone substitution therapy. New admissions (n = 138) were assessed via the Structured Clinical Interview for the DSM III-R (SCID) for presence of Axis I and Axis II disorders and followed for five weeks on standard methadone maintenance. Patients submitted urines three times per week tested for opioids, cocaine, and benzodiazepines. Patients diagnosed with current cocaine dependence (n = 90) submitted a higher proportion of cocaine-positive urines (M = 0.84) than patients diagnosed with past cocaine dependence (n = 32; M = 0.28) and those diagnosed with no cocaine use disorder (n = 14; M = 0.12), P < 0.001. Current cocaine dependence diagnosis accounted for 52% of the cocaine use variance. Patients exhibiting current sedative dependence (n = 25) submitted a higher proportion of benzodiazepine-positive urines (M = 0.60) than patients with past sedative dependence (n = 44; M = 0.20) and those with no sedative use disorder (n = 60; M = 0.05), P < 0.001. Current sedative dependence diagnosis accounted for 37% of the benzodiazepine use variance. Lifetime major depression (12%) and antisocial personality disorder (39%) were the most common nonsubstance use comorbid diagnoses. Axis I nonsubstance use disorder was associated with benzodiazepine use, while Axis II disorder was associated with both benzodiazepine and cocaine use early in treatment (P < 0.05). These data demonstrate the concurrent validity of DSM-III-R cocaine and benzodiazepine use diagnoses, and support the potentially important relationship between drug use and other psychiatric disorders.

The present study evaluated the effects of psychiatric comorbidity on substance use disorder prevalence, HIV risk behavior, and other problem severity in male and female out-of-treatment injection drug users newly registered at a syringe exchange program. Participants (N = 338) were administered the Structured Clinical Interview for the DSM-IV, the Addiction Severity Index, and the Risk Assessment Battery, and classified into one of four diagnostic groups: (1) no antisocial personality disorder (APD) or Axis I psychiatric disorder (N = 162), (2) APD only (N = 74), (3) Axis I psychiatric disorder only (N = 55), or (4) APD plus Axis I psychiatric disorder (N = 47). Psychiatric comorbidity was associated with higher rates of substance use disorder and more HIV risk and other problem severity. In general, participants with both APD and an Axis I disorder exhibited the most problem severity. APD was uniquely associated with higher prevalence for each substance use disorder assessed in this study and with elevated HIV risk. These results support and extend studies conducted with opioid-dependent individuals recruited from treatment and community settings, and reinforce the need to develop interventions to encourage syringe exchange program participants to enroll in treatment.

Motivating methadone patients to include drug-free significant others in treatment : A behavioral intervention

Michael Kidorf; Robert K. Brooner; Van L. King

The present study introduced a novel behavioral approach for encouraging methadone-treated patients to bring drug-free significant other support into treatment. Seventy-five patients referred to high-intensity psychosocial treatment due to chronic drug use were given 3 weeks to identify a drug-free significant other. Patients noncompliant with this intervention were started on a methadone dose taper that was stopped when significant other support was identified. Patients and their significant others were required to attend a significant other group one time per week for a minimum of 6 weeks. Eighty-five percent of the patients brought a drug-free significant other into treatment. Significant others included family members, partners, and friends. Patients who identified significant other support complied with 77% of their scheduled sessions. The results demonstrated that most methadone patients have drug-free support people who are willing to participate in their treatment. These individuals can be utilized to help patients initiate the process of building new drug-free social support networks.

A randomized trial of Web-based videoconferencing for substance abuse counseling

Van L. King; Robert K. Brooner; Jessica M. Peirce; Ken Kolodner; Michael Kidorf

Web-based videoconferencing can improve access to substance abuse treatment by allowing patients to receive counseling services in their homes. This randomized clinical trial evaluates the feasibility and acceptability of Web-based videoconferencing in community opioid treatment program (OTP) participants. Participants that reported computer and Internet access (n=85) were randomly assigned to receive 12weeks of weekly individual counseling in-person or via eGetgoing, a Web-based videoconferencing platform. Fifty-nine of these participants completed the study (eGetgoing=24; in-person=35), with most study withdrawal occurring among eGetgoing participants. Participants exposed to the study conditions had similar rates of counseling attendance and drug-positive urinalysis results, and reported similar and strong ratings of treatment satisfaction and therapeutic alliance. These results support the feasibility and acceptability of Web-based counseling as a good method to extend access to individual substance abuse counseling when compared to in-person counseling for patients that are able to maintain a computer and Internet connection for reliable communication.
