Description

This measure is used to assess the mean of patients' overall* change scores on the BASIS-24® survey. The BASIS-24® survey is administered at the beginning of a treatment episode, with repeat assessments obtained at desired intervals to assess change during or following treatment.

*In addition to an overall change score, six subscales are calculated for the BASIS-24®.

Rationale

The Behavior and Symptom Identification Scale (BASIS-24®) is a consumer-oriented self-report survey. The rationale for the survey measures include: 1) need to measure mental health outcomes associated with specific episodes of care; 2) need to assess outcomes from the consumer perspective; 3) need to measure mental health status according to symptoms and functional problems consumers identify as important and using items empirically derived directly from patients/clients.

The 24-item BASIS-24® was developed to meet the need for a brief, but comprehensive mental health status measure useful in assessing the outcome of mental health treatment from the consumer's point of view. The BASIS-24® is a measure of self-reported difficulty in the major symptom and functioning domains that lead to the need for mental health services. The 24 items assess six major areas of difficulty and/or distress: depression/functioning, relationships, self-harm, emotional lability, psychosis, and substance abuse. 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.

Primary Health Components

Mental health; substance abuse; Behavior And Symptom Identification Scale (BASIS-24®)

Denominator Description

Adult patients 18 years of age and older who completed a BASIS-24® survey at the beginning of psychiatric and/or substance abuse treatment and at another point in the treatment process* (see the related "Denominator Inclusions/Exclusions" field)

*Note: Completion of the second survey may be at discharge/termination or at another follow-up point during the episode of care.

Numerator Description

The mean of patients' overall change scores on the BASIS-24® survey

Note: A change score is not calculated for patients if two or more items from the BASIS-24® survey are left blank (not answered).

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A formal consensus procedure, involving experts in relevant clinical, methodological, public health and organizational sciences
  • Focus groups
  • One or more research studies published in a National Library of Medicine (NLM) indexed, peer-reviewed journal

Additional Information Supporting Need for the Measure

Unspecified

Extent of Measure Testing

Research for BASIS-24® was supported by grant RO1 MH58240 from the National Institute of Mental Health and by the Veterans Administration Health Services Research & Development program. A field test was implemented at 27 treatment sites across the U.S 2,656 inpatients and 3,222 outpatients participated. Factor analytic methods, Classical Test Theory (CTT) and Item Response Theory (IRT) modeling were used to select the most discriminating, nonredundant items for inclusion in the final version of the instrument and to assess its reliability and validity. IRT modeling was used to score the instrument.
