Promoting continuing care adherence among substance abusers with co-occurring psychiatric disorders following residential treatment.

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. This paper explores this question with data from 150 participants who were randomized to receive a behavioral continuing care adherence intervention involving contracting, prompting and reinforcing attendance (CPR), or standard treatment. Fifty-one percent of the participants had one or more co-occurring Axis I or Axis II psychiatric disorders in addition to a SUD diagnosis. Among individuals with co-occurring disorders, those who received the CPR intervention show increased duration of treatment and improved 1-year abstinence rates compared to those who received STX. Additionally, effects of the CPR intervention were generally more pronounced among persons with co-occurring Axis I and/or Axis II disorders than those without these disorders. Treatment implications are discussed.
