Measuring Patient Self-Reported Outcomes

The 24-item Behavior and Symptom Identification Scale, BASIS-24®, is a leading behavioral health assessment tool. 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.

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.

Shorter than its predecessor (BASIS-32®) yet more comprehensive, the BASIS-24® cuts across diagnoses by identifying a wide range of symptoms and problems that occur across the diagnostic spectrum. Validated and found reliable in inpatient, residential, and outpatient settings, BASIS-24® assesses treatment outcomes from the patient perspective.

Typically, BASIS-24® is given at admission and discharge for hospital- or residential-based episodes of care, and at intake/initiation of treatment and then periodically thereafter in partial hospital or ambulatory care settings. The responses to questions indicate how patients feel before and after receiving care.

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 instruction guide provides information on scoring, as well as the syntax for computing weighted scores using SAS. Because of the weighted average methodology, computing BASIS-24® scores by hand is not recommended. Users proficient in statistical analysis can use an off-the-shelf application package such as SAS to compute scores. Alternatively, users may subscribe to BASIS-24® WebScore 2.0, our online scoring and reporting tool for computing case-level and aggregate scores. See BASIS-24® Webscore 2.0.
