Fifty-four probation officers employed by the Iowa's Juvenile Court Services agreed to participate in the study and to be randomly assigned to treatment or standard care. A Multiattribute Utility Measurement Approach (Graham, Flay, Johnson, Hansen, & Collins, 1984) was used to ensure that probation officers assigned to the two conditions were approximately equivalent on level of education, years of experience working with juvenile offenders, number of hours of training on the TTM, and confidence using the TTM in their work.
