New Project - TIRF to conduct study on the behavioral patterns of interlocked offenders and features of effective programs.

TIRF is pleased to announce it has been contracted by LifeSafer to conduct a study on the behavioral patterns of interlocked offenders and on the features of effective programs. Additional funding for this project was provided through a team grant awarded to Dr. Thomas G. Brown, Dr. Marie Claude Ouimet and Dr. Louise Nadeau from the Canadian Institutes of Health Research (CIHR).

The objectives of this project are to replicate and further refine the findings from the 2010 TIRF study, Understanding behavioural patterns of interlocked offenders to inform the efficient and effective implementation of interlock programs, commissioned by the Dutch government.

The new study will analyze the interlock data from as many as 20 jurisdictions in the United States. From these analyses researchers look to answer a number of important questions regarding offender behavioral patterns including the following:

  • Are there different learning curves according to type of violation?
  • Is there a specific profile for persistent offenders who are non-compliant?
  • Are there different types of persistent offenders?
  • How does length of participation affect performance?
  • Does the learning effect differ according to gender, age, mandatory and voluntary participation, and other such parameters?

Dr. Ward Vanlaar, VP Research, will be the principal investigator on the project. It is anticipated that the project will be completed in 2012.
