An intensive outpatient approach for cocaine abuse treatment
Journal of Substance Abuse Treatment, 1995
The Matrix model of outpatient treatment was developed during the 19808 in response to an overwhelming demand for cocaine abuse treatment services. The model was constructed using components based upon empirically supported findings from the substance abuse research field. Over the course of development, data were collected on the treatment model and the model was modified based upon empirical evaluation. A pilot study comparing the Matrix outpatient model with an inpatient hospital treatment program produced preliminary support for the clinical utility of the model. A n open trial comparing publicly and privately funded patients demonstrated that patients with fewer resources were more difficult to engage and retain in this model of outpatient treatment. In a controlled trial, a clear positive relationship was documented between duration and amount of treatment involvement in the Matrix model and positive outcome at 1 year. Due to a variety of methodological issues, the study was not able to answer definitively the question of clinical efficacy. In all of these studies, patients treated with the Matrix model demonstrated statistically significant reductions in drug and alcohol use and improvements in psychological indicators. This body of work, along with the public acceptance the model has received in the treatment community, support the usefulness of this intensive outpatient approach for cocaine abuse. Further research is underway to provide additional controlled information on the value of this treatment approach.
Inpatient vs outpatient treatment for substance dependence revisited
Psychiatric Quarterly, 1993
Miller and Hester's 1986 review of inpatient versus outpatient alcohol treatment studies concluded with no "justification" for inpatient treatment. Further examination of these studies revealed shortcomings such as the use of random assignment designs which excluded psychiatrically-complicated patients. Carrier Foundation's inpatient/outpatient study of private psychiatric patients with alcohol and/or cocaine dependence includes a patient-treatment matching design to address weaknesses in the existing literature. Patients with high psychiatric severity and/or a poor social support system are predicted to have a better outcome in inpatient treatment, while patients with low psychiatric severity and/or a good social support system may do well as outpatients without incurring the higher costs of inpatient treatment. Preliminary results from 183 inpatients and 120 outpatients indicated outpatients, regardless of level of psychiatric severity, were 4 times more likely to be early treatment failures (chi-square = 41.2, df = 1~ p < .01). While the determination of long-term follow-up status of eariy treatment failures is currently underway, this finding underscores the potential risk of early treatment failure in outpatient compared to inpatient substance abuse treatment programs and the importance of addressing the issue of early attrition in conducting outcome analyses.
Outpatient Drug and Alcohol Treatment Programs: Predictors of Treatment Effectiveness
International Journal of Mental Health and Addiction, 2020
Although there is extensive literature on the processes and outcomes of drug and alcohol dependence treatments, little is known about specific predictors of treatment effectiveness. The present study aims to identify the predictors of abstinence in outpatient drug and alcohol dependence treatments, as well as the predictors of treatment effectiveness, according to a biopsychosocial approach. The study followed a cross-sectional research design. Participants (n = 290) were recruited from an outpatient treatment of the Intervention Division in Addictive Behaviors and Dependencies (DICAD), in the northern region of Portugal. A convenience sample was used. Data was collected using questionnaires administered at the facilities of the DICAD, in a private, quiet room. Results indicate that predictors of abstinence were involvement in treatment, psychopathology symptoms, and treatment program (i.e., outpatient drug vs alcohol dependence treatments). The full model of logistic regression analysis was significantly reliable (χ 2 (3) = 33.93, p < 0.001), with 72.5% successfully predicted for the non-substance abuse group and a 53.1% accurate prediction rate for the substance abuse group. The predictors of treatment effectiveness, according to a biopsychosocial approach, were social support and the treatment program. The full model was significantly reliable (χ 2 (2) = 68.28, p < 0.001), with 33.0% successfully predicted for the treatment effectiveness group and a 91.1% accurate prediction rate for the non-treatment effectiveness group. Results suggest that interventions need to focus not only on reducing substance abuse, but also on decreasing psychopathology and promoting therapeutic involvement, acting as predictors of abstinence. Furthermore, interventions must focus on promoting social support and the treatment program, acting as predictors of treatment effectiveness, according to a biopsychosocial approach.
Substance Abuse Intensive Outpatient Programs: Assessing the Evidence
Psychiatric Services, 2014
2 | P a g e -A E B P s y c h i a t r i c S e r v i c e s I O P D r a f t Services; Abstract Objective: Substance abuse intensive outpatient programs (IOPs) are direct services for people with substance use disorders or co-occurring mental and substance use disorders who do not require medical detoxification or 24-hour supervision. IOPs are alternatives to inpatient and residential treatment. They are designed to establish psychosocial supports and facilitate relapse management and coping strategies. This article assesses their evidence base. Methods: Authors searched major databases: PubMed, PsycINFO, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Social Services Abstracts, Published International Literature on Traumatic Stress, the Educational Resources Information Center, and the Cumulative Index to Nursing and Allied Health Literature. They identified 12 individual studies and one review published between 1995 and 2012. They chose from three levels of research evidence (high, moderate, and low) based on benchmarks for the number of studies and quality of their methodology. They also described the evidence of service effectiveness. Results: Based on the quality of trials, diversity of settings, and consistency of outcomes, the level of evidence for IOP 3 | P a g e -A E B P s y c h i a t r i c S e r v i c e s I O P D r a f t research was considered high.

Efficacy indicators of four methods in outpatient addiction treatment
Archives of Clinical Psychiatry (São Paulo)
Background: In Portugal, as far as we know, there are no recent studies that evaluated the comparative efficacy of therapeutic modalities in addiction problems by reference to a holistic and psychosocial model of effectiveness. Objectives: Using a sample of Portuguese patients in outpatient treatment for drug and alcohol abuse, this study aimed to examine if a combined treatment modality (group therapy with individual intervention) had greater overall efficacy when compared to other three types of treatment without group therapy. Methods: This is a correlational and cross-sectional study using a convenience sample of patients (N = 254) from an outpatient treatment in the Intervention Service on Addictive Behaviors and Substance Dependence. At the time of data collection, the patients were attending four types of treatment, such as receiving intervention based on individual psychological counseling (n = 66); receiving individual psychiatric counseling (n = 68); receiving both individual psychological and psychiatric counseling (n = 102); and receiving not only individual counseling (i.e., psychology or psychiatry), but also attending group therapy (n = 18). Results: Using MANOVA and Wilks's multivariate test criterion, there was a significant effect of treatment modality on the global efficacy, Λ = 0.88, F(9, 603) = 3.75, p < 0.0001. Examination of mean estimates indicated that patients in a combined therapeutic modality revealed more treatment involvement compared to patients in other therapeutic modalities without group therapy. Discussion: The results obtained in this study highlight the importance of integrating interventions in a collaborative way. A combined therapeutic modality, adding group therapy, was associated with positive effects, such as more levels of peer support and involvement in treatment, and increasing the individual's probability to remain abstinent.
Inpatient and outpatient cocaine abusers: Clinical comparisons at intake and one-year follow-up
Journal of Substance Abuse Treatment, 1992
Given controversy about the comparative utility of inpatient and outpatient treatment for substance abusers, we compared samples of cocaine-abusing inpatients (n = 149) and outpatients (n = 149) regarding a range of clinical characteristics both at entrance into treatment and one year following this initial assessment. We wished to assess (a) whether inpatient treatment appearedjustified on the basis of more severe clinical problems in this group of patients and (b) the comparative one-year outcome of patients treated in the two conditions. Regarding the presenting clinical picture, inpatients had more severe ratings in numerous areas, with heavier drug use, social impairment, and psychopathology. At one-year follow-up, the direction of clinical ratings had reversed in the two groups, with inpatientsshowing lower problem severity in several areas, particularly cocaine use andpsychopathology. Thus, results of this nonrandomized study of inpatient and outpatient treatment suggest that decisions to hospitalize were made on a rational basis and that inpatient treatment had better long-term efficacy.

Background Substance use disorders are a serious and persistent U.S. public health problem. Although a number of therapy modalities exist, few studies assessed the comparative effectiveness of specific therapies. This study empirically evaluated whether remote intensive counseling (RIC) is more effective than outpatient therapy (OT) in relapse prevention over the period of nine months in patients aged 18-45 years with a history of substance use. Methods The current study utilized a retrospective correlational cross-sectional cohort quantitative research design with multiple between-group comparisons and fixed effects. The sample (n=296) included adults of both sexes, of diverse racial/ethnic backgrounds, and of socioeconomic status (SES) between 18-45 years of age who had been using an illicit addictive substance(s) for at least six months prior and had never participated in any treatment program previously. Individuals with alcohol and/or nicotine co-dependence were excluded. Result and conclusion Remote intensive counseling (RIC) is more effective for patients aged 18-45 years with a history of substance use than outpatient therapy (OT). RIC works better for single or never married females younger than 30-year-old with higher education. The use of RIC for other age and racial/ethnic groups should be guided by whether patients belong to a younger age cohort and/or a specific race/ethnicity.
