RE: Arrest Rates for Case
Management Service Recipients and Others
Don Trites, Director of Research in the Maine Department of
Behavioral and Developmental Services requested information on arrest rates for
two groups of adult consumers of community mental health services: people who
receive case management services and people who do not receive case management
services. This information was requested
in relation to a review of
Extracts from two data sets were
used in this analysis. An extract from
the DDMHS MSR (Monthly Service Report) database provided basic demographic and
service information for adults assigned to Adult Outpatient or Community
Rehabilitation and Treatment Programs during FY2002. For purposes of this analysis, service
recipients were divided into two categories: case management recipients, and
others. Case management recipients
included all individuals for whom CMHCs had reported "Service Planning and
Coordination" and/or Community Supports.
An extract from the Vermont State Police VIBRS (Vermont Incident Based
Reporting System) database provided basic demographic and offense information
for all individuals arrested during FY2002.
Because these data sets do not include unique person identifiers,
Probabilistic Population Estimation was used to determine the number of service
recipients in each group who were also represented in the arrest data set. Arrest rates are reported for six age/gender
categories.
As you will see, there were
statistically significant differences in arrest rates (case management service
recipients compared to others) in four of our six age/gender categories. Among women in the 18-34 year age group, and
both men and women in the 50-65 year old group, recipients of case management
services were significantly more likely to be arrested than others. Among men in the 35-49 year age group,
recipients of case management services were significantly less likely to
be arrested than others.
We will appreciate hearing your observations, interpretations,
and suggestions for further analysis.
