The development and efficacy of a group intervention program for individuals with serious mental illness in jail.

Providing cost-effective means to treat the influx of individuals with serious mental illness entering the correctional system is a major challenge. Failure to provide appropriate mental health treatment may lead to poor outcomes, including recidivism and suicide. Group intervention is an effective and cost efficient way to provide mental health treatment. However, it has been understudied in jail settings. To meet the needs of jail-inmates with serious mental illness, an eight-week group-based module curriculum was developed and studied through analyses of perceived usefulness, retention of key material, and associations with cognitive ability, improvement in psychiatric symptoms, and level of motivation. One week after the completion of a group session, the participants remembered the group topic and at least one key point from the group the majority of the time. Better recall of group material was associated with better overall cognitive ability and motivation at discharge. Participants found the groups to be somewhat to extremely useful 88.4% of the time. Higher levels of usefulness were associated with reduced psychopathology and psychiatric improvement, as well as higher motivation at discharge. The findings provide support for the group intervention and implementation in a jail setting. Further implications are discussed.
