Alcoholics anonymous affiliation at treatment intake among white and black Americans.

OBJECTIVE: Black Americans are overrepresented in the public alcohol treatment system, but may be less likely to use informal services such as Alcoholics Anonymous (AA). Some commentators perceive AA as a white, middle-class organization that is unlikely to appeal to blacks. This epidemiological study considers prior attendance and engagement in AA among 791 black and white men and women entering treatment in public, private and HMO substance abuse programs. METHOD: Clients were interviewed in-person within the first 3 days of inpatient treatment or the first 3 weeks of outpatient treatment. RESULTS: Black clients dominate public detoxification programs and report more drug and employment problems than whites (who report more family problems). Those with prior treatment experiences and those reporting they had gone to AA as part of treatment reported overall higher rates of AA affiliation, with blacks more likely to say they felt like a member of AA (64% vs 54% of whites), had a spiritual awakening as a result of AA (38% vs 27%) and had done service at AA meetings in the last year (48% vs 37%); whites were more likely to have had a sponsor (23% vs 14%) and to have read program literature (77% vs 67%). CONCLUSIONS: Controlling for other effects such as prior inpatient or outpatient treatment, blacks are about twice as likely as whites to report having attended AA as part of treatment (OR = 1.70). More research is needed to understand referral pathways to AA among blacks, and the differential effect this may have on sustained participation in AA and on long-term sobriety.

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.

Professional interventions that facilitate 12-step self-help group involvement.

Facilitating patients' involvement with 12-step self-help organizations, such as Alcoholics Anonymous (AA) and Narcotics Anonymous (NA), is often a goal of substance abuse treatment. Twelve-step-facilitation (TSF) interventions have been found to be more effective than comparison treatments in increasing patients' 12-step group involvement and in promoting abstinence. Future TSF evaluation research should address the effectiveness of incorporating TSF interventions with cognitive-behavioral treatment methods, the relative impact of brief versus extended TSF interventions, and the cost-effectiveness and health care cost-offset of TSF interventions within managed health care systems.

Heterogeneity of celiac disease: clinical, pathological, immunological, and genetic.

In this paper we consider recent new data on the pathological features of gluten sensitivity and on the disease-associated antigens, in the context of a multistage hypothesis that we have been developing for the last five years. This incorporates concepts of oral tolerance induction, mucosal T-cell and antibody-mediated injury, and genetic contributions. Until now, there has been complete agreement that the diagnosis of celiac disease must be based on small bowel histology. There are patients with low-grade gluten-sensitive enteropathy, in whom the only morphological abnormality is a high count of intraepithelial lymphocytes (IEL). Some, but not all, also have positive serum IgA anti-endomysium antibody (AEA). With good techniques, in a properly accredited laboratory, in a patient suspected on clinical grounds to have celiac disease, a positive serum IgA AEA test (perhaps, alternatively, high-titer anti-transglutaminase by ELISA), is virtually diagnostic of the condition. Our hypothesis of a stepwise pathogenesis of severe gluten-sensitive enteropathy is re-examined in the light of these new data. It is evident that there are at least five different levels at which genetic influences may operate.

The relationship of pre-treatment Alcoholics Anonymous affiliation with problem severity, social resources and treatment history.

Little research has examined the relationship of substance abuse patients' prior Alcoholics Anonymous (AA) affiliation to important treatment-related variables. This study of 927 individuals seeking treatment in public, health maintenance organization (HMO) and private-for-profit medical programs, found that 82.8% of patients presented at treatment with a history of AA affiliation. Degree of prior AA affiliation was significantly associated with more extensive prior utilization of formal and informal helping resources, current seeking of treatment in the public sector, having low income, being divorced/separated and having more severe alcohol, employment/support and psychiatric problems. Implications for service delivery and future research are discussed.

Treatment involvement and outcomes for four subtypes of homeless veterans.

A longitudinal study examined treatment services and outcomes in a nationwide sample of 565 homeless veterans who were classified as alcoholic, psychiatrically impaired, multiproblem, or best-functioning. All four groups experienced some improvement in their primary problem area, in employment status, and in residential quality at eight-month follow-up, but there were significant differences in degree of improvement across groups. Implications for the design of homeless programs and policies are discussed.

The Alcoholics Anonymous Affiliation Scale: development, reliability, and norms for diverse treated and untreated populations.

Affiliation with Alcoholics Anonymous (AA) is an important variable to measure in many clinical and research activities. This paper reports on the development of an AA affiliation scale, and demonstrates its utility in a sample of 927 alcohol treatment seekers and 674 untreated problem drinkers. The scale is short (9 items), covers a range of AA experiences, and is internally consistent across diverse demographic groups, multiple health services settings, and treated and untreated populations. The validity of the scale is supported by the findings that treatment seekers report significantly higher AA affiliation than do untreated problem drinkers, and inpatients report higher affiliation than outpatients. Potential clinical and research applications of the scale are proposed.

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.

The influence of posttreatment mutual help group participation on the friendship networks of substance abuse patients.

The effect of 12-step mutual help groups (e.g., Narcotics Anonymous) on members' friendship networks has received little attention. This 1-year longitudinal study examined such effects in a sample of 2,337 male substance abuse inpatients, 57.7% of whom became significantly involved in 12-step activities (e.g., reading program literature, attending meetings) after treatment. An a priori model of the interplay of 12-step involvement) and friendship networks was tested using structural equation modeling, and found to have excellent fit to the data. Twelve-step group involvement after treatment predicted better general friendship characteristics (e.g., number of close friends) and substance abuse-specific friendship characteristics (e.g., proportion of friends who abstain from drugs and alcohol) at follow-up. Results are discussed in terms of how mutual help group involvement benefits patients and how the self-help group evaluation paradigm should be broadened.

Detection of insulin-like growth factor-I and transforming growth factor-beta in whole gut lavage fluid: a novel method of studying intestinal fibrosis.

BACKGROUND: Insulin-like growth factor-I (IGF-I) and/or transforming growth factor-beta (IGF-beta), may be involved in gut fibrous strictures. METHODS: Concentrations of these two peptides have been measured by enzyme-linked immunosorbent assays (ELISAs) in whole gut lavage fluid from 57 patients, of whom 14 had strictures of the small intestine or colon associated with Crohn's disease, irradiation injury, ischaemia or diverticulitis. RESULTS: IGF-I was detected in fluid from 11 of 14 patients with strictures, and 5 of 43 others (P < 0.01). TGF-beta was detectable in all 57 samples and concentrations were unrelated to the presence or absence of strictures. CONCLUSION: Clinical studies of growth factors in intestinal fluid should facilitate research on intestinal fibrogenesis, and the diagnosis of fibrous stricturing in Crohn's disease.

Clinicians' referral and matching of substance abuse patients to self-help groups after treatment.

OBJECTIVE: The clinical practice guidelines for substance use disorders from the American Psychiatric Association (APA) recommend referral of some patients to self-help groups. The purpose of this study was to determine current patterns of referral to self-help groups in substance abuse treatment programs in the United States and compare them with referral recommendations in APA guidelines. METHODS: Directors of all 389 substance abuse treatment programs in the Department of Veterans Affairs health care system completed a mailed survey on posttreatment self-help referral practices. RESULTS: Survey responses indicated that a large proportion of substance abuse patients were referred to Alcoholics Anonymous (79.4 percent), with other self-help organizations receiving a smaller but significant number of referrals. Referrals to 12-step self-help organizations were more common in programs that endorsed a 12-step treatment orientation and that employed a higher proportion of staff members in recovery from substance use disorders. Consistent with APA practice guidelines, clinicians were less likely to make a referral to a 12-step self-help group if a patient was an atheist, had a comorbid psychiatric disorder, or had less severe substance abuse problems. In deciding whom to refer to self-help groups, clinicians also considered other variables that are not addressed in current practice guidelines, such as age and previous involvement in 12-step groups. CONCLUSIONS: Clinicians make extensive use of self-help groups for their patients, as recommended in APA practice guidelines. However, some differences between current practice and recommended practice warrant further investigation.

Social and community resources and long-term recovery from treated and untreated alcoholism.

OBJECTIVE: Long-term studies of the course of alcoholism suggest that a variety of factors other than professional treatment influence the process of recovery. This study evaluated the role of demographic factors, baseline alcohol-related problems and depression, professional treatment, Alcoholics Anonymous (AA) and other social and community resources in predicting remission and psychosocial outcome over 8 years. METHOD: A sample of 628 previously untreated alcoholic individuals was recruited at detoxification units and alcoholism information and referral services. Of these participants, 395 (68.2%) were followed 3 and 8 years later. Most (83.3%) were white (n = 329) and 50.1% (n = 198) were men. At each contact point, participants completed a self-administered inventory that assessed their current problems, treatment utilization, AA participation and quality of relationships. RESULTS: Number of inpatient treatment days received in the 3 years after baseline were not independently related to 8-year remission or psychosocial outcomes. More outpatient treatment in the first 3 years increased the likelihood of 8-year remission, but was not related to psychosocial outcomes. The number of AA meetings attended in the first 3 years predicted remission, lower depression, and higher quality relationships with friends and spouse/partner at 8 years. Extended family quality at baseline also predicted remission and higher quality friendships and family relationships at 8 years. CONCLUSIONS: Given that alcoholism is a chronic, context-dependent disorder, it is not surprising that short-term interventions have little long-term impact. Social and community resources that are readily available for long periods are more likely to have a lasting influence on the course of alcoholism.

Clinical psychologists as psychotherapists: history, future, and alternatives.

As managed care and other cost-containment strategies become central features of the American health care system, doctoral-level clinical psychologists will be increasingly supplanted in the role of psychotherapist by lower cost providers such as social workers, marriage and family counselors, and masters-level psychologists. To provide one basis for clinical psychologists to make judgments about their role in psychotherapy; this article describes what the field was like before psychotherapy became a core activity and then compares the present transition with its historical counterpart: the opening up of the psychotherapy profession to doctoral-level clinical psychologists after World War II. History suggests that efforts to resist the current changes will be unsuccessful and that the most adaptive coping strategy for clinical psychologists is to take advantage of the transition by reenvisioning training and practice of clinical psychologists.

World view change in adult children of Alcoholics/Al-Anon self-help groups: reconstructing the alcoholic family.

Although 12-step self-help groups have become extremely popular in U.S. society, clinicians and researchers have devoted little attention to how these groups affect members. This project used naturalistic and qualitative methods to examine the processes through which committed members of self-help groups for adult children of alcoholics experience alterations in their perceptions of family of origin. Results suggest that world view transformation in the family of origin domain involves learning to define the family as pathological, assigning responsibility for this pathology to a disease, forgiving oneself, accepting that one was adversely affected by the family's problem, and ultimately learning to accept one's parents' shortcomings.

Life domains, alcoholics anonymous, and role incumbency in the 3-year course of problem drinking.

This study examined the course of problem drinking among 439 individuals over 3 years, using a life domains perspective that distinguishes life stressors and social resources in different contexts. More severe chronic financial stressors both predicted and were predicted by more alcohol consumption and drinking-related problems. Among social resources, Alcoholics Anonymous was the most robust predictor of better functioning on multiple outcome criteria. Support from friends and extended family also predicted better outcomes; this effect was stronger for individuals who were low on primary role incumbency (i.e., who were unemployed and/or did not have a spouse/partner).
