A comparative evaluation of substance abuse treatment III. Examining mechanisms underlying patient-treatment matching hypotheses for 12-step and cognitive-behavioral treatments for substance abuse.

This study examined several hypotheses for matching patients to 12-Step and cognitive-behavioral (CB) treatments in a multisite evaluation of VA inpatient substance abuse programs. A total of 804 male patients in five 12-Step programs, and 1069 male patients in five CB programs completed an intake, discharge, and 1-year follow-up questionnaire. The findings did not support the notion that certain patient characteristics would differentially predict better outcomes after 12-Step and CB treatment This conclusion held when the purest 12-Step and CB programs were used, and when patients who received the full dose of treatment (i.e., treatment completers) were examined separately. Process analyses of the hypothesized mechanisms underlying the patient-treatment matching effects did not yield the expected links among patient characteristics, proximal outcomes, and 1-year outcomes. Our conclusion is that there is no advantage to matching men with substance abuse problems to 12-Step or CB treatments based on the patient attributes measured here.

A comparative evaluation of substance abuse treatment IV. The effect of comorbid psychiatric diagnoses on amount of treatment, continuing care, and 1-year outcomes.

Recent surveys of the substance abuse patient population have shown a striking increase in the proportion of patients with a comorbid psychiatric disorder. In this study, patients with substance abuse and psychotic, anxiety/depressive, or personality disorders were compared with patients with only substance use disorders on treatment experiences and outcomes. Regardless of dual diagnosis status, patients generally improved on both substance use and social functioning outcomes after substance abuse treatment. At the 1-year follow-up, dually diagnosed patients, and patients with only substance use disorders, had comparable substance use outcomes. However, patients with major psychiatric disorders, specifically psychotic and anxiety/depressive disorders, fared worse on psychological symptoms and employment outcomes than did patients with personality disorders and only substance use disorders. Although there were some group differences on the amount of index treatment received and continuing care, the overall pattern of relationships between treatment variables and outcomes was comparable for the patient groups. In addition, there was no diagnostic group by treatment orientation matching effects, which indicated that the dual diagnosis patient groups improved as much in 12-Step as in cognitive-behavioral substance abuse programs.

A comparative evaluation of substance abuse treatment: V. Substance abuse treatment can enhance the effectiveness of self-help groups.

Affiliation with Alcoholics Anonymous (AA) and other 12-Step self-help groups is becoming more common at the same time as professional substance abuse treatment services are becoming less available and of shorter duration. As a result of these two trends, patients' outcomes may be increasingly influenced by the degree to which professional treatment programs help patients take maximum advantage of self-help groups. The present study of 3018 treated veterans examined how the theoretical orientation of a substance abuse treatment program affects (1) the proportion of its patients that participate in self-help groups, and, (2) the degree of benefit patients derive from participation in self-help groups. Patients treated in 12-Step and eclectic treatment programs had higher rates of subsequent participation in 12-Step self-help groups than did patients treated in cognitive behavioral programs. Furthermore, the theoretical orientation of treatment moderated the outcome of self-help group participation: As the degree of programs' emphasis on 12-Step approaches increased, the positive relationships of 12-Step group participation to better substance use and psychological outcomes became stronger. Hence, it appears that 12-Step oriented treatment programs enhance the effectiveness of 12-Step self-help groups. Findings are discussed in terms of implications for clinical practice and for future evaluations of the combined effects of treatment and self-help groups.

Outcomes of the treatment climate in psychiatric and substance abuse programs.

This study examines how key aspects of the treatment climate are related to program differences in the aggregate behaviors of patients residing in 89 psychiatric or substance abuse facilities. More active support, personal expression, and practical orientation were related to better patient functioning, more patient activity in the facility and in the community, and more use by patients of the program's health-treatment services and social-recreational activities. These results held for both patients' and staff members' consensual perceptions of the treatment climate. On the whole, these aspects of the treatment milieu were especially beneficial for groups of patients with greater psychiatric impairment.

Life circumstances and personal resources as predictors of the ten-year course of depression.

A 10-year naturalistic study of 313 patients who entered treatment for unipolar depression and a community comparison group of 284 nondepressed adults was conducted. We compared life stressors, social resources, personal resources, and coping among patients who were remitted (N = 76), partially remitted (N = 146), or nonremitted (N = 91). Compared with the controls and the remitted patients, the partially remitted and nonremitted patients consistently experienced more life stressors and fewer social resources, were less easygoing, and relied more on avoidance coping. A less easygoing disposition, fewer close relationships, and more reliance on avoidance coping were associated with higher odds of experiencing a course of partial remission or nonremission. In addition, more depressive symptoms and medical conditions predicted nonremission.

Family and extrafamily resources and the 10-year course of treated depression.

A group of 313 depressed patients and 284 controls was assessed at baseline (treatment intake for the patients) and at 1-year, 4-year, and 10-year follow-ups. Stably remitted patients achieved levels of family and extrafamily resources that were comparable with those of the controls. Although partially remitted and nonremitted patients' social resources improved, they continued to show deficits in these areas relative to controls and stably remitted patients. Several indexes of social resources predicted stable remission: more family independence, fewer family arguments and less conflict, and more helpful friends and activities with friends. Assessment of social resources at treatment intake and short-term follow-ups can help identify and provide intervention foci for patients at risk for nonremission of depression.

Determinants of the treatment climate in psychiatric and substance abuse programs: implications for improving patient outcomes.

This study examined determinants of the treatment climate in 89 psychiatric and substance abuse programs. Clearer policies giving patients more control, and more health and treatment services, were related to more supportive, autonomous, expressive, and practically oriented milieus. In contrast, more policy choice and daily living assistance were associated with less support, personal expression, and practical orientation. Programs in which staff had more paraprofessionals and better team functioning, and in which patients had more social resources and better mental functioning, tended to be more supportive and to have more emphasis on autonomy, personal expression, and practical orientation. Based on these results, we suggest some guidelines on how to change the treatment milieu to benefit patients' adjustment.

Risk factors for sustained nonremission of depressive symptoms: a 4-year follow-up.

Previous studies have suggested that a considerable number of depressed patients suffer from sustained or repeated episodes of depressive symptoms. We developed a risk factor index based on data obtained at admission to treatment predicting sustained nonremission of depressive symptoms over 4 years for a sample of 370 unipolar depressed inpatients and outpatients. The six risk factors for sustained nonremitted depression are: less education, more severe initial depressive mood and ideation, secondary major depression, prior treatment, comorbid medical conditions, and fewer close relationships. These findings suggest that identification of these risk factors before selecting treatment type and intensity may improve long-term clinical outcomes.

Evaluating substance abuse treatment process models: I. Changes on proximal outcome variables during 12-step and cognitive-behavioral treatment.

OBJECTIVE: This article provides data on the early linkages in the treatment process chains that are thought to underlie two prevalent approaches to substance abuse treatment-traditional 12-step treatment and cognitive-behavioral treatment. The focus is on the during-treatment changes on "proximal outcomes" that, according to the treatment theory underlying each modality, patients are supposed to undergo or achieve in order to experience a positive "ultimate outcome." METHOD: In all, 3,228 men receiving treatment in 15 Department of Veterans Affairs substance abuse treatment programs were assessed at treatment entry and at or near discharge from inpatient programs that had desired lengths of stay of 21-28 days. RESULTS: Between intake and discharge, patients in 12-step programs improved more than did C-B patients on proximal outcome variables assumed to be specific to 12-step treatment (e.g., attending 12-step meetings, taking steps), whereas patients in cognitive-behavioral programs made no greater change (and in a few cases, less change) than did 12-step patients on proximal outcome variables assumed to underlie cognitive-behavioral treatment (e.g., self-efficacy, coping skills). CONCLUSIONS: These findings suggest that the proximal outcomes thought to be specific to cognitive-behavioral treatment are actually general proximal outcomes of both 12-step and cognitive-behavioral treatment.

The staff workplace and the quality and outcome of substance abuse treatment.

OBJECTIVE: The study examined the connection between the staff work environment and staff members' beliefs about treatment, the quality of the treatment environment, patients' involvement in treatment and self-help activities, and patients' improvement during treatment. METHOD: Patient care staff (N = 329) in 15 substance abuse treatment programs reported on the characteristics of their work environment and on their beliefs and treatment orientations about substance abuse. Patients in these programs (N = 3,228) reported on the treatment environment, their participation in treatment and self-help activities, and their treatment goals, confidence in achieving these goals, and coping skills at intake to and discharge from treatment. RESULTS: Staff in supportive and goal-directed work environments were more likely to espouse disease model beliefs and a 12-step orientation toward substance abuse treatment. These work environments were associated with more supportive and goal-directed treatment environments. Patients in these treatment environments participated in more substance abuse, educational and social, and family treatment services, were more involved in self-help groups (as indicated by attending more meetings, reading 12-step materials, and having a sponsor and friends in such groups), were more satisfied with the program, improved more during treatment (as indicated by abstinence goals and confidence in maintaining abstinence, less depression, and more substance abuse and general coping skills), and were more likely to participate in outpatient mental health care after discharge. CONCLUSIONS: More goal-directed work environments are associated with more goal-directed treatment environments and patients' engagement in treatment and improvement. The staff work environment is an important component of the substance abuse treatment system.

Influence of outpatient treatment and 12-step group involvement on one-year substance abuse treatment outcomes.

OBJECTIVE: This study examined whether substance abuse patients self-selecting into one of three aftercare groups (outpatient treatment only, 12-step groups only, and outpatient treatment and 12-step groups) and patients who did not participate in aftercare differed on 1-year substance use and psychosocial outcomes. METHOD: A total of 3,018 male patients filled out a questionnaire at intake and 1 year following discharge from treatment. Patients were classified into aftercare groups at follow-up using information from VA databases and self-reports. RESULTS: Patients who participated in both outpatient treatment and 12-step groups fared the best on 1-year outcomes. Patients who did not obtain aftercare had the poorest outcomes. In terms of the amount of intervention received, patients who had more outpatient mental health treatment, who more frequently attended 12-step groups or were more involved in 12-step activities had better 1-year outcomes. In addition, patients who kept regular outpatient appointments over a longer time period fared better than those who did not. CONCLUSIONS: Encouraging substance abuse patients to regularly attend both outpatient aftercare and self-help groups may improve long-term outcomes.

First-time admissions with alcohol-related medical problems: a 10-year follow-up of a national sample of alcoholic patients.

OBJECTIVE: We estimated the rate of first-time hospital admission over 10 years with alcohol-related medical problems among a large national sample of patients with diagnosed alcohol abuse disorders. METHOD: We identified a nationwide cohort of all patients (N = 46,680) discharged in 1980 from all Department of Veterans Affairs (VA) medical centers with alcohol-related diagnoses. Two comparison cohorts also were identified: patients with musculoskeletal disorders (N = 18,231) and a random sample of nonalcoholic patients (N = 45,204). Using secondary databases, ICD-9-CM coded diagnostic information was collected for all VA inpatient admissions these patients experienced over the decade following their index hospitalizations. Admission rates within age strata and age/race standardized rates were computed. Adjusted rate ratios were estimated using Poisson regression. RESULTS: Alcoholic patients were at substantial risk of admission for multiple medical disorders. Admission rates varied for patients of different ages. Those who were between 50 and 59 years of age during their index hospital stay were at the highest risk of admission with an alcohol-related medical disease over the subsequent decade. CONCLUSIONS: The admission rates for these medical disorders among alcoholic patients provide an important baseline estimate of individual patients' risk profiles and may help providers set priorities among diagnostic tests.

Predicting the development of late-life late-onset drinking problems: a 7-year prospective study.

There has been little empirical study of risk factors for the development of late-life late-onset drinking problems. In the current prospective study, we compare two groups of older adults who, at a baseline assessment, were nonproblem drinkers: individuals who developed drinking problems over the course of the next 7 years (n = 77) and those who did not (n = 197). Late-onset problem drinkers reported mild to moderate drinking problems and spontaneous remission rates were high. Compared with stable nonproblem drinkers, late-onset problem drinkers at baseline were more likely to report incipient problems, heavier alcohol consumption, greater friend approval of drinking, more reliance on avoidance coping strategies, were more likely to smoke, and were less likely to have acute medical conditions that could potentially be complicated by alcohol consumption. Contrary to expectation, life stressors did not predict drinking problem onset. However, compared with stable nonproblem drinkers, late-onset problem drinkers were more likely to have a history of responding to stressors and negative affect with increased alcohol consumption.

Policy-relevant program evaluation in a national substance abuse treatment system.

This article discusses recent trends in public and private substance abuse services and offers suggestions on how the evaluation of such services can inform clinical practice and policy making. This analysis focuses particularly on the Department of Veterans Affairs (VA), which operates the largest substance abuse treatment system in the United States. In recent years, there has been an erosion of services for substance abuse outside the VA. In contrast, due to increased funding from the U.S. Congress, the VA significantly expanded substance abuse treatment from 1990 to 1994. However, efforts to "reinvent" and downsize government initiated a reversal of this growth trend in 1994, and VA services may shrink further as the system becomes more decentralized and adopts managed care strategies from the private sector. Drawing from the VA Program Evaluation and Resource Center's (PERC) experience of evaluating the VA system and working with federal policy makers, this article presents examples and suggestions for making evaluations of substance abuse treatment systems more useful in policy discussions and in day-to-day clinical practice.

Community residential program policies, services, and treatment orientations influence patients' participation in treatment.

The study sought to identify community residential program characteristics that predict patients' participation in treatment and to examine the association between these characteristics, participation, and outcomes at discharge from treatment. A sample of 2,790 patients with substance abuse disorders was assessed at entry into and discharge from 87 community residential facilities (CRFs). The CRFs were assessed using a survey that obtained information about program size and staffing, policies and services, and treatment orientation. High expectations for patients' functioning, clear policies, structured programming, a high proportion of staff in recovery from substance abuse problems, and more emphasis on psychosocial treatment were associated with patients' participation in program services and activities. Higher expectations for functioning and a strong treatment orientation enhanced participation more among better functioning patients; program support and structure enhanced participation more among impaired patients. Participation in treatment independently predicted outcomes at discharge even after both patient and program characteristics were controlled. These findings show that community residential program policies, services, and treatment orientations play a key role in influencing patients' engagement in treatment, which, in turn, improves patients' outcomes at discharge.

Twelve-step and cognitive--behavioral treatment for substance abuse: a comparison of treatment effectiveness.

The comparative effectiveness of 12-step and cognitive-behavioral (C-B) models of substance abuse treatment was examined among 3,018 patients from 15 programs at U.S. Department of Veterans Affairs Medical Centers. Across program types, participants showed significant improvements in functioning from treatment admission to a 1-year follow-up. Although 12-step patients were somewhat more likely to be abstinent at the 1-year follow-up, 12-step, C-B, and combined 12-Step-C-B treatment programs were equally effective in reducing substance use and improving most other areas of functioning. The finding of equal effectiveness was consistent over several treatment subgroups: Patients attending the "purest" 12-step and C-B treatment programs, and patients who had received the "full dose" of treatment. Also, patients with only substance abuse diagnoses, those with concomitant psychiatric diagnoses, and patients who were mandated to treatment showed similar improvement at the 1-year follow-up, regardless of type of treatment received. These data provide important new evidence supporting the effectiveness of 12-step treatment.

Gender differences in the relations between depressive symptoms and drinking behavior among problem drinkers: a three-wave study.

Prior research has suggested that the relation between depression and drinking behavior is stronger for women than for men. In a 3-wave study spanning 3 years, we examined the nature of reciprocal relations between depressive symptoms and drinking behavior among women (n = 207) and men (n = 207) seeking detoxification or referral services for their drinking problems. Latent variable structural equation modeling analyses revealed that more baseline depression was associated with less alcohol consumption 1 year later among women and men. However, later on, more depression predicted heavier alcohol consumption, but only among women. Among women and men, heavier alcohol consumption predicted more subsequent depression, although the timing of this effect differed by gender. Reciprocal effects between depression and drinking problems were found only among men.
