BASIS-24® Validation in English and Spanish

The BASIS-24® survey was developed, field tested, and validated and a scoring algorithm was developed with R01 MH58240 funding from NIMH. Participating sites included 13 inpatient and 14 outpatient programs. An additional study was conducted from 2003-2007 with R01 MH58240 funding from NIHM to create a Spanish version of the BASIS-24® which was also field tested and validated.

Validation of Perceptions of Care (PoC) for Inpatient/Residential Partial Programs

To validate the inpatient version of the PoC, almost 7,000 PoC surveys were completed from 1998 through 2000 by patients in inpatient behavioral health and substance abuse programs. The results of this study were four domains (Continuity and Coordination of Care, Communication/Information Received from Provider, Interpersonal Aspects of Care, and Global Evaluation of Care) and the development of a 100-point score for each domain. McLean eBASIS remains committed to continually evaluate this tool, including updating the form in 2011 and adding three questions (not used to calculate domain scores) in 2012.

Gender Invariance of the Behavior and Symptom Identification Scale (BASIS-24®) Factor Structure

The psychometric properties of the BASIS-24® have never been analyzed for its validity and reliability across gender. The purpose of this study is therefore to assess the acceptability of the six-factor model and find evidence of functional and scalar equivalence to establish equivalence across-gender.

Projects in Progress


Behavior and Symptom Identification Scale (BASIS-24®) Community Norms and Clinical Benchmarks for Patient Care

While the BASIS-24® is widely used, no community normative data or clinical benchmark has been published at this point. Currently underway, this project will provide clinical "cut" scores which may be used to help determine if a patient is experiencing symptoms in the clinical or normal range. Benchmarks will be useful to clinicians to determine how sick their patient is in comparison to the overall population as well as to set treatment goals.

Readmission within 30 Days of Discharge

This is a study that uses archival data to examine data related to what factors, including illness severity, social support, and following-up with aftercare, are associated with readmission. In addition to gathering archival data, data will also be collected from nurses, social workers, clinicians, and Mental Health Specialists based on their experiences what factors are predictive of readmission.

Validation of the Behavior and Symptom Identification Scale (BASIS-24®) in the Adolescent Population

The eBASIS team consistently works to provide you with the most cutting-edge tools. This goal has brought about the most recent project, the Adolescent Pilot Study of the BASIS-24®. The reliability, validity, and psychometric properties of the BASIS-24® are known to be strong when tested with adults ages 18 and older. Testing the BASIS-24® with adolescents will demonstrate if the tool is a valid measure of symptoms and functioning in that population. If BASIS-24® cannot be validated in adolescents, development will begin of a new tool that license holders can confidently use with adolescents.
