LSI-R Technical Brochure
The LSI-R™ assessment is a quantitative survey of offender attributes and offender situations relevant for making decisions about levels of supervision and treatment. The instrument’s applications include assisting in the allocation of resources, helping to make probation and placement decisions, making appropriate security level classifications, and assessing treatment progress. The 54 LSI–R items are based on legal requirements and include relevant factors for making decisions about risk level and treatment. Probation officers, parole officers, and correctional workers at jails, detention facilities, and correctional facilities complete the semi-structured interview with offenders. They then use the interview together with collateral information to complete a QuikScore™ form. The results are converted to cumulative frequencies on a ColorPlot™ Profile. Users have the option of profiling the Total LSI–R score against the Canadian norms or the U.S. norms.
LSI–R scores are proven to help predict parole outcome, success in correctional halfway houses, institutional misconduct, and recidivism. This predictive validity is partly a result of the method of its construction. The item content was developed to reflect three primary sources: recidivism literature, the professional opinions of probation officers, and the social learning perspective of social behavior. Scores can then be used in conjunction with professional judgment to arrive at valid placement decisions. An 8-item screening version (LSI–R:SV) and a youth version (YLS/CMI) are also available from MHS.
The LSI–R assessment can be easily used by counselors, physicians, psychologists, and correctional professionals, including probation officers, youth workers, social workers, and other trained professionals and paraprofessionals. A professional with advanced training in psychological assessment or a related discipline must assume responsibility for the use, interpretation, and communication of the results. The professional must have b-level qualifications, which require that, as a minimum, he or she has completed courses in psychological testing and measurement at a post-secondary level or has equivalent training.
The LSI–R instrument contains the following scales, with the number of items in each listed in parentheses. Criminal History (10) Education/Employment (10) Financial (2) Family/Marital (4) Accommodation (3) Leisure/Recreation (2) Companions (5) Alcohol/Drug Problems (9) Emotional/Personal (5) Attitudes/Orientation (4)
The item responses are summed, resulting in a Total score. Additional factors can be considered in making placement decisions, and space is provided for professional overrides.
