The Contracts, Prompts, and Reinforcement (CPR) intervention has demonstrated an ability to increase the duration of continuing care participation following substance use disorder (SUD) treatment, resulting in improved treatment outcome. The current project was a qualitative pre-implementation study aimed at identifying barriers and facilitators to implementation of CPR using an evidence-based quality improvement (EBQI) approach. Formative evaluations were conducted with staff from residential SUD treatment programs across three VA sites, and key informant interviews were completed with opinion and program leaders.

Differential rates of schizophrenia and paranoia symptoms have been found for Black and White individuals. Paranoid personality disorder shares symptoms with schizophrenia, yet has received minimal attention with regard to potential racial differences. In a sample consisting of 180 substance use disorder treatment-seeking individuals, the association between the diagnosis of paranoid personality disorder and the variables of race, cannabis use disorder, and income were examined.

The contracting, prompting and reinforcing (CPR) aftercare intervention has improved treatment adherence and outcomes in a number of clinical trials. In multisite randomized clinical trial 92 graduates of two intensive substance use disorder programs who received CPR were compared to 91 who received standard treatment (STX). The CPR group evidenced increased frequency of aftercare group therapy attendance and near significant findings suggested that more CPR than STX participants completed 3 months (76 vs.

Continuing care following initial substance use disorder treatment often is associated with improved treatment outcomes and evidence-based interventions (EBIs) have been developed in this area. However, rates of patient participation in continuing care treatment and mutual help groups (MHGs) are low and a large gap exists between the existing EBIs and actual clinical care. This paper uses the Consolidated Framework for Implementation Research (CFIR; Damschroder et al.

Epidemiological data from treatment and community samples of individuals with substance use disorders indicate that the rates of co-occurring psychiatric disorders are high and that these disorders are associated with poor treatment adherence and outcomes. A growing body of research indicates that continuing care adherence interventions positively impact treatment outcome. However, it is unclear whether these interventions are effective for individuals with co-occurring psychiatric disorders.

Although continuing care is strongly related to positive treatment outcomes for substance use disorder (SUD), participation rates are low and few effective interventions are available. In a randomized clinical trial with 150 participants (97% men), 75 graduates of a residential Veterans Affairs Medical Center SUD program who received an aftercare contract, attendance prompts, and reinforcers (CPR) were compared to 75 graduates who received standard treatment (STX). Among CPR participants, 55% completed at least 3 months of aftercare, compared to 36% in STX.

This study examined the convergent validity of the Timeline Followback (TLFB) for individuals with comorbid (Axis I and/or Axis II) psychiatric disorders in a sample of persons (N=150) engaged in residential treatment for substance use disorders (SUDs). Approximately one-half of the sample was diagnosed with at least one comorbid psychiatric disorder. Validity was assessed comparing data from the TLFB with data from the Addiction Severity Index (ASI) and collateral reports.

Contracting and prompting clients to attend substance abuse treatment aftercare substantially improves treatment adherence and outcome. However, this approach has not been evaluated for improving entry into initial treatment. We recruited 102 individuals scheduled to begin a 28-day substance use disorder (SUD) residential treatment program and randomly assigned them to receive either our standard treatment (STX) or STX plus attendance contracting and prompting (CP).

Although adherence to aftercare therapy in substance abuse treatment is associated with improved outcome, little research has explored the effects of adherence interventions on outcome. We compared 20 graduates of our 28-day intensive treatment program who received a standard aftercare orientation with 20 graduates who received this intervention plus social reinforcement of aftercare group therapy attendance. The social reinforcement group showed less alcohol use than the standard care group at a 6-month follow-up assessment as measured by the Addiction Severity Index (ASI), but not less drug use.
