Measuring client clinical progress in therapeutic community treatment. The therapeutic community Client Assessment Inventory, Client Assessment Summary, and Staff Assessment Summary

The therapeutic community (TC) Client Assessment Inventory (CAI), Client Assessment Summary (CAS), and Staff Assessment Summary (SAS) are instruments developed from a comprehensive theory of TC treatment and recovery. They measure client self-report and staff evaluation of client progress along 14 domains of behavior, attitude, and cognitive change. The present article reports on the development of the instruments and findings from an analysis of data on 346 clients in TC treatment; including scale properties and cross-sectional client differences by treatment tenure. The instruments were administered over a 1-year period at two residential TC facilities. Findings indicate that both client and staff instruments reliably differentiate client clinical changes during treatment and client self-ratings are initially consistently higher than staff ratings. Clarifying and measuring changes in the individual during treatment is the first step in the effort to understand the change process and what steps can be taken to improve treatment effectiveness.

Pretest assessment as a component of safer sex intervention: a pilot study of brief one-session interventions for women partners of male injection drug users in New York City

This pilot study evaluated whether brief safer sex interventions for women partners of male injection drug users significantly influenced perceptions of partner risk, human immunodeficiency virus (HIV) knowledge, correct condom usage, and self-reported consistent safer sex (abstinence or 100% of vaginal-penile intercourse acts protected by male or female condoms). The study also examined the impact of pretest assessment on those variables since pretest assessment may challenge participants' current knowledge, safer sex practices, and partner communication techniques. The study randomly assigned participants to pretest or no pretest assessment. Each group was also assigned randomly to a presentation modality: (1) safer sex pamphlet review only, (2) pamphlet review with demonstration of several safer sex alternatives, or (3) pamphlet review with skills practice to mastery with one safer sex alternative of the woman's choice. For the last two conditions, a 35-minute interactive session covered prevention efficacy of safer sex methods for HIV, sexually transmitted infections, pregnancy, correct use, eroticization, local cost and availability, and partner objections. At 7 weeks postintervention, a higher proportion of women who took pretest assessment reported consistent safer sex (66.7%) compared to those without pretests (55.6%). Assignment to the interactive interventions (skills or demonstration) had little additional impact over pretest assessment for these women. Among women who did not take pretests, the interactive interventions had strong effects; 76.9% reported consistent safer sex versus 33.3% in the pamphlet review group. There were additional specific effects for pretest assessment on HIV knowledge and partner risk perception and for interactive intervention on correct condom usage. Brief interventions appear to have some positive short-term effects. Pretest assessment may be an important component of brief interventions.

Enhanced treatment outcomes for cocaine-using methadone patients

Cocaine dependent methadone patients were randomly assigned to 6 months of high intensity cognitive-behavioral therapy or low intensity therapy. A repeated measures ANOVA was conducted with patients stratified on severity of cocaine use at baseline. Both treatment groups showed significant and equivalent reductions in cocaine use during the post-treatment period. Completing either therapy and lower cocaine severity at baseline were associated with lower proportion of cocaine-positive urines across a 48-week post-treatment period. Examination of the treatment x cocaine severity interaction provided some evidence that high-severity patients improved more if exposed to high intensity treatment than to low intensity treatment. Positive outcomes for therapy completers relative to non-completers increased over time. The results are consistent with several clinical trials showing that: (1) participation in treatment is associated with reductions in cocaine use; and (2) the relationship between treatment intensity and outcome is not linear and may better be explained by an interaction between patient and treatment factors.

Bromocriptine for cocaine dependence. A controlled clinical trial

On the basis of the dopamine depletion theory, bromocriptine has been tested to treat cocaine withdrawal and dependence. The authors conducted a 6-week study with 1 week of pretreatment observation and 5 weeks of a randomized, double-blind, placebo-controlled clinical trial of bromocriptine for DSM-III-R-defined cocaine dependence in methadone-maintained male patients. The bromocriptine group (n = 24) did not differ from the placebo group (n = 26) in self-reported cocaine use, proportion of positive urine toxicology samples, craving for cocaine, resistance to cocaine use, or mood symptoms between the pretreatment baseline and the last week of the clinical trial. Both groups showed significant reduction in self-reported frequency of cocaine use, resistance to craving, and mood symptoms during participation in the protocol. The results of this study are consistent with recent clinical and laboratory findings in primary cocaine users. Despite initially promising pilot studies, recent evidence does not support the efficacy of bromocriptine to reduce cocaine use or craving.

Daily cocaine use patterns: effects of contextual and psychological variables

This study identifies factors that predict daily cocaine use among clients in a methadone maintenance program who participated in a cocaine treatment trial. Cocaine use decreased the longer clients remained in treatment, and the amount of cocaine used depended upon the day of the week, with Saturday typically having the greatest use and Sunday having the least. Logistic regression analyses showed that several other factors were related to daily cocaine use: peak cocaine craving, resistance to use cocaine, and several triggers or stimuli to use cocaine. These stimuli included receiving money, being offered cocaine, and seeing cocaine and/or related paraphernalia. However, even with these variables controlled, day of the week and time in treatment continued to be significant predictors. This suggests that (a) other time-varying variables need to be included in order to fully account for cocaine use variation from day to day and (b) time in treatment is a robust predictor of reduced cocaine use despite the strong influences of craving, external stimuli, and day of the week.

Treatment intensity and reduction in drug use for cocaine-dependent methadone patients: a dose-response relationship

This study examined the impact of treatment intensity on cocaine use. Seventy-seven cocaine-using methadone patients were enrolled in a six-month, structured, manual-driven, cognitive-behavioral treatment program. Sessions consisted of five individual and/or group sessions per week. At intake subjects showed extensive polydrug abuse, psychiatric comorbidity, criminal histories, and HIV risk behaviors. Treatment intensity was measured by dividing number of sessions attended into quartiles. Paired comparisons, within treatment quartiles, were made between subjects' intake and six-month self-reports of cocaine use. Subjects in quartiles two through four showed significant reductions in frequency of cocaine use at follow-up, with subjects who received the most treatment showing the greatest reductions in cocaine use. Bivariate and multivariate analyses showed that treatment sessions attended remained a strong predictor of reduction in cocaine use at follow-up, even after controlling for drug use at intake and background variables. The results indicate that there is a substantial treatment dose-response relationship.

Lactate provocation of panic attacks. II. Biochemical and physiological findings

Thirty-one of 43 patients with panic disorder or agoraphobia with panic attacks and none of 20 normal controls panicked in response to infusions of sodium lactate. Before receiving lactate, patients showed higher heart rates than controls and also signs of hyperventilation. During lactate infusion, patients who did not panic, nevertheless, developed higher lactate and pyruvate levels and greater ionized calcium and pH changes than controls. Lactate-induced panic attacks were regularly accompanied by biological changes consistent with hyperventilation and central noradrenergic activation and irregularly by elevation of plasma norepinephrine and cortisol levels. Panic attacks were not associated with changes in epinephrine or calcium levels or pH. Baseline arousal increased the likelihood of panic during lactate infusion. It is hypothesized that lactate-induced panic primarily involves central noradrenergic discharge with inconsistent peripheral manifestations.

Lactate provocation of panic attacks. I. Clinical and behavioral findings

To assess the pharmacologic and phenomenologic comparability of lactate-induced and naturally occurring panic attacks, patients meeting DSM-III criteria for panic disorder or agoraphobia with panic attacks were infused with 0.5M racemic sodium lactate before and after successful drug treatment. Lactate-induced and naturally occurring panic attacks were symptomatically similar. Following treatment, the patients' response to lactate did not differ from that of normal controls, whereas the pretreatment panic rate was much higher. These data suggest that lactate acts, by as yet unidentified mechanisms, to trigger the same panic attacks as occur spontaneously in vulnerable persons.
