MMPI profiles of opiate addicts: predicting response to treatment.

Although many studies document the use of the MMPI to classify opiate users, the predictive validity of the resulting subgroups is rarely reported. In this study, we used cluster analysis to identify MMPI profile types that predicted differential response to methadone maintenance treatment. Participants (N = 151) completed MMPIs shortly after entry into treatment. Cluster analysis of MMPI scores produced four distinct subgroups that differed significantly in severity of psychosocial problems measured at admission and on the mean number of drug-free urine specimens submitted during the 24-week study period. Cluster 1 participants evidenced low levels of psychological disturbance, improved their urinalysis results over time, and submitted the most posttest drug-free urine specimens. Cluster 2 was the only other group that improved significantly over time, even though these patients were the most psychologically disturbed. The results suggest the relation between psychological problems and outcome may be more complex than is commonly assumed.

Reinforcing operants other than abstinence in drug abuse treatment: an effective alternative for reducing drug use.

This study examines the effectiveness of using vouchers to reinforce either the provision of urine samples testing negative for illicit drugs (UA group) or the completion of objective, individually defined, treatment-plan-related tasks (TP group). A third group was assigned to the clinic's standard treatment (STD group). Participants were randomly assigned to groups after a 6-week baseline-stabilization period. Urine specimens were collected thrice weekly throughout the study. In the UA condition, participants earned $5 (U.S. dollars) in vouchers for each drug-free urine submitted. In the TP condition, participants earned up to $15 in vouchers per week for demonstrating completion of treatment plan tasks assigned by their counselors. Contingencies were in effect for 12 weeks, after which all participants received the clinic's standard treatment. Urinalysis results indicate that the TP intervention was significantly more effective in reducing illicit drug use than either the UA or STD interventions. These effects were maintained with a trend toward continuing improvement for the TP groups even after contingencies were discontinued.

Impact of comorbid personality disorders and personality disorder symptoms on outcomes of behavioral treatment for cocaine dependence.

Studies have revealed a significant adverse impact of comorbid personality disorders on treatment tenure and outcome in a variety of psychiatric and substance abuse populations. We investigated whether this negative relationship also exists among 137 urban, poor, cocaine abusers in behaviorally oriented treatment. Axis II diagnoses were generated categorically using the SCID-II as well as dimensionally using numbers of SCID-II symptoms within diagnostic categories. Contrary to expectations, there were no significant differences between subjects with and without various categorical personality disorders on any outcome measures. Categorical Axis II diagnoses were also minimally correlated with drug use severity, depression, and anxiety at intake, indicating that these were not potential coveriates of outcome. However, dimensional analyses of personality symptoms generated from the SCID-II accounted for substantial proportions of variance in treatment outcomes. Implications of these data for Axis II assessment and drug treatment planning are discussed.

Structured interview versus self-report test vantages for the assessment of personality pathology in cocaine dependence.

The study compared structured interview (SCID-II) and self-report test (MCMI-II) vantages for the detection and characterization of personality pathology among 144 urban, poor, cocaine-addicted individuals seeking outpatient treatment. Diagnostic agreement was inadequate for most disorders, and the instruments at best shared only modest common variance. Positive predictive power was poor for all MCMI-II scales, though negative predictive power was good to excellent. This lends support for the use of the MCMI-II as a screening measure to rule out Axis II disorders; however, confirmation of positive diagnoses will require follow-up interview assessment. Future development of self-report personality inventories for substance abusers should focus on controlling for the acute dysphoric effects of drug use and related dysfunction, expanding attention to Cluster B content domains, and incorporating more objective criteria for assessing paranoia and "odd/eccentric" traits.

Assessment of coercive and noncoercive pressures to enter drug abuse treatment.

This paper reports preliminary data derived from a standardized interview scoring procedure for detecting and characterizing coercive and noncoercive pressures to enter substance abuse treatment. Coercive and noncoercive pressures stemming from multiple psychosocial domains are operationalized through recourse to established behavioral principles. Inter-rater reliability for the scoring procedure was exceptional over numerous rater trials. Substantive analyses indicate that, among clients in outpatient cocaine treatment, 'coercion' is operative in multiple psychosocial domains, and that subjects perceive legal pressures as exerting substantially less influence over their decisions to enter treatment than informal psychosocial pressures. Implications for drug treatment planning, legal and ethical issues, and directions for future research are proposed.

Decline in self-reported dysphoria after treatment entry in inner-city cocaine addicts.

This study examined self-reported dysphoria in 82 consecutive admissions to intensive outpatient treatment for cocaine abuse on whom data for the Beck scales for depression, anxiety, and hopelessness were available for intake and 4 subsequent weeks with no more than 1 missing data point. Mean scores on the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) decreased significantly between intake and Week 1, with no further significant changes from Weeks 1-4. Similar drops in the rate of clinically significant BDI and BAI scores also were observed. Scores on the Beck Hopelessness Scale (BHS) showed no significant changes. By Week 4, rates of clinically significant depression, anxiety, and hopelessness were similar (17%, 13%, and 16%, respectively). These findings suggest that assessing depression and anxiety using the BDI and BAI in this population should be postponed for at least 1 week after intake and that intake levels of self-reported mood may be inappropriate baseline measures for evaluating treatment effects.

Situations occasioning cocaine use and cocaine abstinence strategies.

We interviewed 265 cocaine-experienced methadone patients about situations that occasioned their cocaine use and strategies they used to avoid cocaine use. Subjects identified an average of 15 situations that occasioned cocaine use. The three most frequently identified were having the drug present (86% of subjects), being offered the drug (85%) and having money available (83%). Subjects reporting fewer situations also reported longer periods of lifetime abstinence (p < 0.01). A principal components analysis extracted 10 groups of situations that were most frequently identified in combination. Subjects identified a median of seven strategies for avoiding cocaine use; however, there was large inter-subject variability. This variance was not accounted for by demographic variables, employment status or treatment experience. The three strategies identified most frequently were avoiding people and places (81%), thinking about what they could lose (76%) and leaving the situation (66%). The total number and type (reactive vs. proactive) of strategies identified by subjects had no relationship to cocaine abstinence, although four specific strategies (thinking about what could be lost, leaving the situation, moving to a new area and using a different drug) were positively correlated with cocaine abstinence. We discuss implications of these results for clinical practice.

Comparison of MMPI-2 and MMPI clinical scales and high-point scores among methadone maintenance clients.

Methadone client volunteers completed the Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1967) and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) on consecutive days. MMPI-2 T-scores were lower by a mean of 4.7 on the clinical scales; when 5 points were added to MMPI-2 T-scores the mean difference was 2.3. Rank order of subjects on scale T-scores was not significantly different between the two instruments. High-point similarity for clinically elevated profile pairs ranged from 61% to 92%, depending upon definition of similarity.

Problem-solving types among high-risk IDUs. Potential treatment implications.

This research investigated whether high-risk injection drug users (IDUs) manifest distinct types, or profiles, of interpersonal cognitive problem-solving (ICPS) abilities. Four measures of ICPS, the Means-Ends Problem-Solving procedure (MEPS), Optional Thinking Test (OTT), Awareness of Consequences Test (ACT), and Causal Thinking Test (CTT), were administered to 140 IDUs who volunteered for NIDA Demonstration Projects in Newark and Jersey City, NJ, to study high-risk behaviors in drug users and their sexual partners. At time of initial contact, none of the subjects was currently enrolled in a treatment program. Hierarchical and nonhierachical cluster analyses were used with the MEPS, OTT, ACT, and CTT scores, and five IDU problem-solving types were identified. These types represented below-average, causal, generational, consequential, and above-average problem-solving skills. A rational conceptualization of potential treatment implications for each of these types of IDU problem solvers is discussed.

Major psychotherapeutic modalities for heroin addiction: a brief overview.

This article provides a brief overview of recent literature on major psychotherapeutic modalities for heroin addiction. These modalities include psychotherapy, behavior therapy, cognitive-behavioral therapy, family therapy, social skills training approaches, and therapeutic communities. It highlights studies with stronger research design and methodology, many of which are theory-based, and discusses what appear to be the "active ingredients" in these modalities which contribute to successful treatment outcome. It concludes that there is an increasing convergence of theory and research in the field of heroin addiction treatment, making the designing of treatment programs based on empirical knowledge more feasible.
