DETAILS:

Written at a 3rd-grade reading level, the IORNS is a 130-item self-report measure that assesses static risk, dynamic risk/need, and protective strength factors as they relate to recidivism, treatment need, and management.

• Consists of four indexes, eight scales, 14 subscales, and two validity scales.

• T scores, percentiles, confidence intervals, and qualitative classifications are provided for the normative samples.

• Can be administered and scored by persons who do not have training in forensic or clinical psychology or psychiatry, with supervision and interpretation by a licensed or certified professional.

• Standardized and validated with offenders (men ages 18-75 years and women ages 18-60 years); offender samples included incarcerated and probated general and sexual offenders.

• Community adult/college normative sample (men and women ages 18-75 years) approximates 2003 U.S. Census proportions for race/ethnicity and educational status.

• Demonstrates significant correlations with self-reported criminal history variables, including number of nonviolent and violent crimes and number of times in jail/prison among male and female offenders.

• Significantly related to self-reported criminal, familial, and substance use history variables (e.g., past physical and sexual abuse) among female offenders.
