In an average of 36 seconds, patients can be screened for Major Depressive Disorder in English or Spanish anywhere in the world at levels of precision and accuracy never previously achieved.
Because the CAT-MHTM adapts to the changing severity of the underlying illness, the same questions are not asked upon repeat testing. This permits high frequency mental health measurement without response bias produced by repeated administration of the same set of items.
In Emergency Department (ED) Studies the CAT-MHTM identified 22% of patients with Major Depressive Disorder, 7% at a severity level in need of immediate treatment, and 3% with serious suicide risk. None of these suicidal patients were identified by ED clinicians. These patients had significant increases in ED visits and hospitalizations (doubling of the rate) in the year following their ED visit. None of these patients had a psychiatric diagnosis.
In two minutes each the severity of depression, anxiety, and mania can be measured with precision equal to what would have taken hours to achieve with traditional fixed length tests.
Traditional mental health testing fixes the symptom-items and allows the precision to vary. The CAT-MHTM fixes constant precision across the severity continuum and allows the items to vary both in number and content.
Adaptive Testing Technologies (ATT) designs, tests, and implements Computerized Adaptive Tests for depression, anxiety, mania/hypomania, and suicide (CAT-MHTM).
