Mental health versus substance abuse treatment programs for dually diagnosed patients.

The aim of this study was to assess the similarities and differences of patients with co-existing psychiatric and substance use disorders attending treatment in either a mental health setting or a substance abuse treatment setting. A total of 129 patients were assessed, including 65 individuals from the substance abuse treatment center and 64 individuals from the mental health program. Treatment records were reviewed for diagnoses and sociodemographic data. While the two groups were highly similar with regard to age and ethnicity, there were significant differences in psychiatric profile, with the substance abuse treatment group having less severe diagnoses and no patients with schizophrenia, while the mental health treatment group had a majority of patients with schizophrenia. Other differences in the two groups, such as marital and parental status, disability status, and medical problems appeared to be directly linked with the aforementioned diagnostic profile. These data suggest important differences in characteristics of patients with comorbid disorders that appear to be dependent on the type of treatment program they attend. For the most effective management, integrated treatment programs should be aware of these differences and tailor service provision accordingly.

Chronically mentally ill patients with and without substance use disorders: a pilot study.

The study was designed to assess characteristics of chronic mentally ill patients with and without a substance use disorder. Study patients (n=48) had either psychiatric illness alone (they received conventional psychiatric rehabilitation) or dual diagnoses (they received mental illness and substance abuse services). All patients were administered the Brief Symptom Inventory (BSI), the Client Satisfaction Questionnaire, the Perceived Social Support Scales, and the Composite International Diagnostic Interview. Higher proportions of dually diagnosed patients had schizophrenia, had higher scores on the BSI, and were less satisfied with treatment.

A description of precipitants of drug use among dually diagnosed patients with chronic mental illness.

In this report, we describe patients' perceptions of the chronological occurrence of their mental illness and substance abuse. The patients were enrolled in a community mental health center and received dual diagnosis treatment from an affiliated psychiatric rehabilitation program. Using a questionnaire designed to address this issue, we assessed patients' perceptions of support currently being received at the treatment program and how beneficial they perceived this support to be. In addition, we assessed why substance use was a coping strategy in times of perceived stress early in life and whether this behavior has changed to date. Assessing the perception of the sequence of co-occurring disorders among patients enables us to better understand the factors that precipitate substance use and exacerbate mental illness. This knowledge may aid in the design of effective treatment strategies for this population of patients.

Severely mentally ill patients with and without substance use disorders: characteristics associated with treatment attrition.

We aimed to describe characteristics associated with attrition for patients in community mental health treatment with chronic mental illness with and without substance use disorders. Baseline assessments included symptom severity, treatment satisfaction, social support, and a structured diagnostic interview. Treatment attrition was assessed at six months. At six months, 36% of the dual diagnosis group (n = 25), and 61% of the mental illness alone group (n = 23) were lost to follow-up. Attrition in the dually diagnosed group tended to be associated with less satisfaction with treatment, and higher mean symptom scores. There were no characteristics associated with attrition in the group of patients with mental illness alone. However, client satisfaction tended to increase among the mental illness alone patients that were successfully followed. The dually diagnosed group that remained in treatment had a significantly lower mean treatment satisfaction score than the mental illness alone group at six months. This type of investigation should aid in patient care and evaluation of treatment programs for persons with severe mental illness and co-occurring substance use disorders.
