BASIS-24®
2019 – 2023

Timberline Knolls utilizes the 24-item Behavior and Symptom Identification Scale, BASIS-24®, a leading behavioral health assessment tool. The BASIS-24® identifies a wide range of symptoms and problems that occur across the diagnostic spectrum. Grounded in the latest scientific methods of survey development and validation, the BASIS-24® underwent extensive field testing as part of a multiyear research and development process. BASIS-24® is validated in both Spanish and English.  The 24 questions are scored using a weighted average algorithm that gives an overall score and scores for six subscales for the following domains of psychiatric and substance abuse symptoms and functioning: Depression and Functioning, Relationships, Self-Harm, Emotional Lability, Psychosis, and Substance Abuse.

The BASIS-24® is designed for use by mental health providers, researchers, purchasers of mental health services, accreditation agencies, and internal quality assurance departments to measure the change in consumer self-reported symptom and problem difficulty over the course of treatment. The outcome measure is administered at admission, mid-point, and discharge. Participation is voluntary and encouraged.


I can truly say I’m not just surviving, I’m thriving. Thank you, thank you, thank you! I cannot express my gratitude enough for the staff who never gave up on me. I was hardly easy to deal with but was ALWAYS treated with respect and love. You guys are life changers and role models. My life is better because of the advice y’all have given me.
