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.


Timberline Knolls’ PHP program has given me my life back. Stepping down to PHP with supportive living from Residential care was a huge help in allowing me to re-acclimate back into day-to-day life and responsibilities and prepared me for ultimate success in living independently when returning home. I was treated with love, respect, and care while I relearned how to be an adult in recovery. I owe my recovery to Timberline Knolls PHP. The staff, community, and supportive living made the difference between succeeding after discharge and meeting my goals, and staying stuck in my old ways and habits. I would recommend this program to anyone looking to change their life for the better.
