The 24-item Behavior and Symptom Identification Scale, BASIS-24®, is a leading behavioral health assessment tool designed to assess the outcome of mental health or substance abuse treatment from the client’s perspective. Typically, BASIS-24® is given at admission and discharge for inpatient or residential programs, and at intake/initiation of treatment and then periodically thereafter in partial hospital or ambulatory/outpatient care settings. 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 and has been validated and found reliable in inpatient, residential, partial and outpatient settings. BASIS-24® is also validated in both Spanish and English.
BASIS-24® inquires as to the degree or frequency of difficulty that the respondent has been experiencing during the past week. The 24 items are scored using a weighted average algorithm that gives an overall score as well as scores for six subscales. The 24 items assess six major areas of difficulty and/or distress including: Depression/Functioning, Relationships, Self-Harm, Emotional Lability, Psychosis, and Substance Abuse.
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. BASIS-24® is not diagnosis-specific, but was designed to cut across diagnoses, acknowledging the wide range of symptoms and problems that occur across the diagnostic spectrum.
