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.


Going to Timberline Knolls was one of the best decisions I have ever made! I highly recommend you go here for treatment! You will come out knowing how to cope better with life!
