Jail diversion• Court-based jail diversion programs: a growing
policy response to problem of CJ involvement among adults with SMI– ~560 diversion programs are currently operating in 47 states
• Various program models—MH court structure, others use alternative approaches
• Common criteria include:– SMI diagnosis– Many exclude felony or violent offenders– Indication that mental illness was a contributing factor in referral
offense, determination of “suitability”– Willingness to comply with court-arranged treatment plan
Jail diversion: what we know now
• Generally, significant reductions in recidivism are evident– But improvements are modest
• Evidence lacking on which program components predict successful diversion– Access to treatment services. . . ?– A legal mechanism that uniquely engages
participants and promotes their success. . . ?
CT’s jail diversion program• CT one of two states with an innovative, statewide jail
diversion program
• Community MH clinicians based in courts – Work with court personnel to identify and divert eligible adults
SMI
• Reports that some judges opt to first put some individuals in jail for a few days to enhance motivation for entering treatment and avoiding a jail sentence
- Enhance motivation - Ineffective, inappropriate - Good set up for Tx - Traumatizing
– Detox– Stabilization

Research QuestionsCompared to immediate diversion, to what
extent do brief jail stays before initiating diversion improve outcomes by. . .
1) further reducing use of crisis-driven health
care (i.e., hospitalization and ED visits)?
2) further reducing recidivism (subsequent arrest and incarceration)?
Study DesignPart 1: Observational study of effect of pre-
diversion brief incarcerations• Quasi-experimental study of administrative records from
public behavioral health and CJ systems for adults with SMI who participated in a statewide jail diversion program in Connecticut during FYs 2006 & 2007
Part 2: Diversion observations and personnel interviews
• Observations of jail diversion proceedings in CT courts • Informal interviews with key jail diversion and court
personnel
Study MeasuresDependent variables• Psychotropic medication adherence
– Medication possession ratio
• Targeted outpatient service use
• Hospitalizations for MH or substance abuse treatment
• ED visits
• Rearrest

Summary and next steps
• Explore moderator analyses – Estimating effects of jail before diversion on
specific sub-groups (e.g., dual Dx, felony index arrest)
• Future research – Examine role of Tx adherence more closely
• How/why jail first improve Tx adherence• Why that doesn’t translate to improved health and
public safety outcomes
CT site visit and interviews• Semi-structured interviews with key players in
jail diversion program– Judge, bail commissioners, public defender, PD social
worker, court coordinator, jail diversion clinicians
• Key themes emerged– Where goal is to divert clients at arraignment, public
safety comes first– “Frequent fliers” among most likely to get some pre-
diversion jail time; many perceived to be willingly making bad choices
– Need for detox, general stabilization in combination with lack of Tx slots also often means jail time first
Propensity Score Method
• Step 1:– Case control match with local greedy algorithm
• Is a local matching algorithm, i.e., making optimal matching decisions at each step without attempting to make the best overall global matching decision
• Once a match is made, the match is not reconsidered• Study group cases are ordered and sequentially matched to the nearest unmatched
control group cases• If more than one unmatched control matches to a case, the control is random selected• 92 cases matched
• Step 2:– Distance score within same quintile
• For 10 un-matched cases, distance scores were computed between treated cases unmatched control cases with the same quintile
• Unmatched control case with smallest absolute distance is selected• All 102 matched, and all covariates were balanced between study and control groups
