The purpose of this randomized controlled trial ( = 268) at a Federally Qualified Health Center was to evaluate the outcomes of a care management intervention versus an attention control telephone intervention on changes in patient activation, depressive symptoms and self-rated health among a population of high-need, medically complex adults. Both groups had similar, statistically significant improvements in patient activation and self-rated health. Both groups had significant reductions in depressive symptoms over time; however, the group who received the care management intervention had greater reductions in depressive symptoms.

To evaluate a Multiple Family Group (MFG) education and support intervention for individuals with Spinal Cord Injury (SCI) and their primary caregivers. We hypothesized that MFG would be superior to an Education Control Group (EC) for improving patient activation and coping skills, social supports, and relationship functioning. A large free-standing inpatient and outpatient rehabilitation facility.

Background: Over 12,000 individuals suffer a spinal cord injury (SCI) annually in the United States, necessitating long-term, complex adjustments and responsibilities for patients and their caregivers. Despite growing evidence that family education and support improves the management of chronic conditions for care recipients as well as caregiver outcomes, few systematic efforts have been made to involve caregivers in psycho-educational interventions for SCI. As a result, a serious gap exists in accumulated knowledge regarding effective, family-based treatment strategies for improving outcomes for individuals with SCI and their caregivers.

This study assessed the social, demographic and clinical determinants of whether an opioid-dependent patient received buprenorphine versus an alternative therapy. A retrospective cohort analysis of opioid-dependent adults enrolled in Group Health Cooperative between January 1, 2006 and December 1, 2010 was performed. Increasing the number of physicians with DATA waivers in a region and living in a relatively-populated area increased the likelihood of being treated with buprenorphine, indicating that lack of access is a potential barrier.

Objective: This study evaluated the feasibility, acceptability, and helpfulness of implementation of multifamily group treatment for traumatic brain injury (TBI) among veterans who sustained a TBI during the wars in Iraq and Afghanistan and their families or caregivers.

Methods: Veterans and their family members who participated in an open clinical trial (August 2010-March 2011) of multifamily psychoeducation for TBI at two Veterans Affairs medical centers were invited to one of three focus groups. Participants were asked about problems experienced before and during the intervention, aspects of treatment that were helpful, and improvements that would facilitate effective implementation of multifamily group treatment for TBI.

Objective: This study evaluated the initial efficacy and feasibility of implementing multifamily group treatment for veterans with traumatic brain injury (TBI).

Methods: Veterans at two Veterans Affairs medical centers were prescreened by their providers for participation in an open trial of multifamily group treatment for TBI. Enrollment was limited to consenting veterans with a clinical diagnosis of TBI sustained during the Operation Enduring Freedom-Operation Iraqi Freedom era, a family member or partner consenting to participate, and a score ≥20 on the Mini-Mental State Examination.

Objective: The objective was to determine if patients hospitalized with a primary medical diagnosis and any co-occurring serious mental illness (SMI) were more likely than patients without any co-occurring SMI diagnosis to experience a subsequent medical hospitalization.

Method: This was a longitudinal cohort study of 925,705 adult persons (aged 18+ years). Patients hospitalized in Washington State from 2004 to 2008 were followed through 2009 (for an average of 43 months).

The impact of multiple-family group treatment (MFGT) on outpatient and inpatient mental health service utilization of 97 persons with schizophrenia was investigated. Participants were randomly assigned to standard care (n = 44) or standard care plus MFGT (n = 53). Service use for a year prior to randomization, the 2-year study period, and a 1-year follow-up were examined.

An estimated 20% of children suffer from psychological disorders and only 10-20% receive adequate treatment. A lack of empirically supported treatments is one reason why relatively few children receive treatment for their psychological difficulties. Multiple-family group treatment (MFGT) is an empirically supported intervention for adults with chronic mental illnesses that may be an effective treatment for children with psychological disorders.

The goals of the current study were to determine whether incorporating disability benefit management into combined outpatient psychiatric/addiction treatment was feasible and clinically useful for managing severely mentally ill, substance-abusing patients over time, and then if patients in this program would demonstrate the first-week-of-the-month increased substance abuse and hospitalizations shown in other studies. Forty-four patients were studied for an average of forty weeks, with little treatment or study dropout. There was no evidence in either the schizophrenic/cocaine abuser or the broader diagnostic sample of the cyclic first-of-the-month pattern of substance use and hospitalizations observed in other studies.

To evaluate the feasibility and efficacy of a program to manage Social Security disability benefits in a clinical sample of patients with severe mental illness and co-occurring substance dependence, 41 patients were randomly assigned to have their benefits either contingently or noncontingently managed through their mental health center. Contingent management involved adjustments to the type or frequency (not amount) of disability benefits and payments for study participation based on ratings of substance use, money management, and treatment follow-through. The patients with contingent management used significantly less alcohol and drugs and showed much better money management than those with noncontingent management.

The study tests whether psychiatric services utilization may be predicted from administrative databases without clinical variables equally as well as from databases with clinical variables. Persons with a psychiatric hospitalization at an urban medical center were followed for 1 year postdischarge (N = 1384.) Dependent variables included statewide rehospitalization and the number of hours of outpatient services received.

Use of drugs and alcohol by 43 predominantly male outpatients who had severe mental illness and a comorbid substance use disorder were assessed weekly through the ratings of experienced dual disorder case managers and through blinded research urine toxicology tests. The percentage of weeks in which drugs or alcohol were used was calculated on the basis of one or both assessments. The case managers often missed drug use over the weekends, which was detected by the urine toxicology tests.

Objectives: Outpatient and inpatient mental health service outcomes for outpatients with schizophrenia or schizoaffective disorder who received psychoeducational multiple-family group treatment were compared with outcomes for similar patients who received standard care.

Methods: A total of 106 outpatients with schizophrenia or schizoaffective disorder who were receiving services from a large community mental health center were randomly assigned to receive standard care or standard care plus multiple-family group treatment. The two-year multiple-family intervention consisted of weekly group sessions designed to educate patients and their family members about the biological basis of mental illness and treatment, to improve illness management and coping skills, and to provide social support.
