The Brief Multidimensional Assessment Scale (BMAS): A Broad Measure of Patient Well-Being.

Objective: This article discusses the development and initial clinimetric and psychometric properties of the Brief Multidimensional Assessment Scale (BMAS). The BMAS is an ultrabrief multidimensional measure of global patient well-being that can be used at every clinic visit to assess several facets of patients' perception of themselves, regardless of their diagnosis, at a moment in time and over the course of treatment.

Methods: Data were collected from 499 adults in the community as well as from psychiatric and medical inpatient and outpatient settings. Participants completed questionnaires as part of their standard care at inpatient and outpatient medical and psychiatric settings or completed them online (community sample).

Results: Results indicate that the BMAS measures four discrete dimensions: the ability to get things done, emotional support in important relationships, quality of life, and sense of purpose in life. The scale demonstrates concurrent validity with other measures and discriminates between nonclinical participants and participants from most clinical contexts.

Conclusions: The BMAS demonstrates promising initial psychometric properties. It offers clinicians a multidimensional measure of their patients' well-being, regardless of diagnosis, that can be used to monitor well-being at each routine appointment and over time.
