We aim to advance treatment and public safety by providing validated, technology-enhanced psychological assessments that help clinicians identify, treat, and monitor individuals who have sexually offended.
Accurate assessment is the cornerstone of effective treatment.
Cornerstone Assessment
Who We Are
Cornerstone Assessment is a family-run nonprofit organization dedicated to advancing treatment effectiveness and public safety through scientifically validated, technology-driven psychological assessment tools. We are the developers of the MIDSA (Multidimensional Inventory of Development, Sex, and Aggression), a comprehensive, research-based assessment system built on more than two decades of clinical and empirical work.
What We Do
We design and deliver advanced assessment solutions that support clinicians, correctional systems, researchers, and treatment programs working with individuals who have sexually offended. Our core platform, MIDSA, is a computerized self-report assessment that generates detailed clinical reports to help professionals identify risk factors, understand developmental and behavioral histories, guide individualized treatment, and monitor change over time.
In addition to our assessment tools, we provide training, consultation, and ongoing support to ensure effective implementation in real-world settings.
Why It Matters
Evidence-based assessment is critical to both effective treatment and community safety. Our tools help professionals make informed, consistent, and defensible decisions about which treatment targets require the greatest therapeutic focus in a Risk/Needs/Responsivity framework to maximize risk management and enhance treatment efficacy.
Our Approach
We focus on:
- Scientific rigor grounded in validated research
- Practical application in clinical and correctional settings
- Innovation through technology and continuous development
- Collaboration with clinicians, researchers, and public agencies
