Bradshaw, Richard Alfred
These data were collected in an attempt to cross-validate
the 1984 and 1985 versions of the Iowa model for assessing risk of
offending while on parole by applying the model to a Michigan sample of
male parolees over a follow-up period of two and one-half years.
Different measures of predictors such as prior criminal history,
current offense, substance abuse history, age, and recidivism on parole
are available. The first file contains information on parolees such as
demographic characteristics, drug use history, prior criminal history,
risk scores, and parole history. The second file includes parolees'
detailed criminal histories including the total number of violent and
nonviolent felony arrests and dates, and charges and dispositions of
each arrest with a maximum of eight arrests.
One or more data files in this study are set up in a non-standard format, such as card image format. Users
may need help converting these files before they can be used for analysis.
The public-use data files in this collection are available for access by the general public.
Access does not require affiliation with an ICPSR member institution.
