Overview

What level of accuracy does the SAPROF-SO provide for predicting recidivism as compared to other, validated assessments?

Summary

The Structured Assessment of Protective Factors against Sexual Offending (SAPROF-SO)  is a 14-item instrument designed to evaluate protective factors across three core domains: Resilience, Adaptive Sexuality, and Prosocial Connection & Reward. The primary aims of the current study by Carr et al. (2025) were to build upon the initial validation of this instrument by: 

1. Establishing the SAPROF-SO’s ability to predict success on supervised release in a high-risk sample of civilly committed men in the United States. 

2. Examining its incremental predictive validity over and above the widely used Static-99R. 

3. Determining the specific predictive utility of the individual SAPROF-SO subscales. 

Method:  The study sample consisted of 170 adult males
