Behavioral Health Index (BHI) Outcomes and Phase Theory: First Look

BHI data clusters

by Laura Dietzen, Manager of Behavioral Health Analytics

Tridiuum ONE® users are familiar with our Behavioral Health Index, or BHI. It is a composite score unique to the platform that measures a patient’s behavioral health. The score is based on the tenets of measurement-based care and psychotherapy outcomes theory, calculated from questions covering multiple domains (overall well-being, depression, anxiety, and functioning). The domains carry different weights in the calculation, with overall well-being and functioning being the most heavily weighted.

More than 80% of clinicians we surveyed felt the BHI assessment adequately reflected their clinical judgement in at least half of their cases. In recent years, our team has continued research on BHI outcomes, in conjunction with the GAD-7 and PHQ-9, and what they can tell us about outcomes to improve treatment. Here is a brief background on our findings, which will be released in 2023.

The BHI is based on both phase theory and dosage theory. Phase theory posits three sequential phases of therapeutic outcome: remoralization, remediation and rehabilitation.

Phase Theory
  • Remoralization: improvement in a sense of general wellbeing
  • Remediation: reduction of symptoms
  • Rehabilitation: restoration of functioning

In simpler language, an individual will first begin to report “feeling better” (remoralization), then see themselves experiencing less symptoms (remediation), followed by the ability to function better in life (rehabilitation). In combination with dose theory (relationship between several sessions and therapeutic outcomes), it has been hypothesized that different facets of patients’ conditions change at different and predictable rates over the course of psychotherapy sessions.

For upcoming research on how BHI scores cluster, stay tuned for the release of our new white paper in 2023.
