The CAT-MH™

The CAT-MH™ is a suite of measures validated for depression, anxiety, mania/hypomania, substance use disorder, psychosis, PTSD, social determinants of health, adult ADHD, and suicidality.

The K-CAT™

Our children’s version of the CAT-MH™ has been validated for youth ages 7 to 17. The K-CAT™ includes self-rated and parent/caregiver-rated modules for: depression, anxiety, mania/hypomania, ADHD, SUD, conduct disorder, ODD, and suicidality.

It’s as easy as 1, 2…

In an average of 2 minutes per module, patients can be screened for anxiety, depression, substance use disorder, psychosis, suicidality, PTSD, social determinants of health, adult ADHD, and mania/hypomania, with precision equal to what would have taken hours to achieve with traditional fixed length tests. This process can be further streamlined by integrating with our API.

1

CREATE A TAILORED ASSESSMENT

Select the modules you’d like to administer to your patient and have the assessment sent directly to the patient’s mobile phone number or email address.

2

COMPLETE THE ASSESSMENT

The patient completes the assessment and a completion notification is immediately sent to the clinician. 

3

VIEW THE RESULTS

The results are immediately available for review by the clinician. These results can be exported, printed, or integrated directly to the Electronic Health Record. 

Applications of the CAT-MH™

Large-scale screening and monitoring of depression and anxiety in integrated primary care and behavioral health care settings is a natural application of this work and is already in practice in several major institutions. Below are just a handful of the current and potential applications of this technology.

POPULATION SCREENING

The CAT-MH™ is being used as a 1st stage diagnostic screener in the largest national survey of mental health and substance use disorder survey in history, conducted by SAMHSA and implemented by RTI.

HOSPITAL SYSTEMS

The University of Chicago completed a CAT-MH™ study of 1,000 patients in the emergency department (ED) who came in for a non-psychiatric indication. They were screened for depression using the CAD-MDD, measured for depression severity using the CAT-DI and suicide risk.

STATE ENTITIES

The CAT-MH™ is being used for
state-wide assessment of mental health disorders in the child welfare system where hundreds of caseworkers have been trained in its use.

RESEARCH INSTITUTIONS

High-frequency monitoring, even hourly in response to fast-acting new psychiatric treatments (e.g. ketamine and deep brain
stimulation) are now possible because the same items are not repeatedly administered to the same patient.

UNIVERSITY SYSTEMS

We have contributed to a large-scale university student screening and monitoring system to screen, triage and provide measurement-based care to college students remotely in real time and to determine which students need more intensive treatment.

INSURERS

Insurers can now monitor the progress of patients through treatment without the patient needing to be in the clinic for testing.

Is your organization looking to provide remote measurement-based care?

Because our tools are cloud-based, they can be administered on any internet-capable device via the patient’s mobile phone number or email address. Organizations are increasingly utilizing our tools for digitally-enabled triage. Contact us to find out more.

Overview of Our Tools

The CAT-MH™ and K-CAT™ utilize computerized adaptive testing where different individuals may receive different symptom items which adaptively target their specific impairment level. This allows for the first ever, true measurement of complex mental and behavioral health disorders.

GROUNDED IN STATISTICS

Our tools are based on multi-dimensional item response theory (MIRT). Based on MIRT procedures, estimates of items (e.g., difficulty, discrimination) and individuals (e.g., severity of depression) can be obtained to more efficiently identify suitable item subsets for each individual. MIRT weighs more severe items more heavily than less severe items in deriving a test score.

LANGUAGES

The CAT-MH™ is available in English, Spanish, and Chinese. The K-CAT™ is available in English and Spanish. Both the CAT-MH™ and K-CAT™ have built-in selectable audio to aid in literacy issues and further ease of use. 

LARGE ITEM BANK

The CAT-MH™ adaptively selects a small optimal set of items from a large bank of approximately 1,500 items and the K-CAT™ has a separate item bank of 2,120 items. Instead of fixing the items and allowing the precision of measurement to vary, we fix the precision of measurement and allow the items to vary. The result is a dramatic increase in the precision of measurement with a dramatic decrease in the burden of measurement for the patient and the complete elimination of clinician burden.

VALIDATED MEASURES

The CAT-MH™ and K-CAT™ have been validated against structured clinican diagnostic interviews (e.g. SCID-DSM-5) so it can provide diagnostic profiles for a large number of disorders and suicide risk. They are the only suites of mental health measures that have been fully validated against structured clinical interviews.

API INTEGRATION

The CAT-MH™ and K-CAT™ can be leveraged via API for integration into Electronic Health Records. We have fully integrated the CAT-MH™ into the Epic EHR at the University of Chicago and developed clinical workflows designed around the integration. For example, the CAT-MH™ identified 22% of patients with MDD, 7% at a severity level in need of immediate treatment, and 3% with serious suicide risk. None of these 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. None of thse patients had a psychiatric diagnosis.

REMOTE-FRIENDLY

The CAT-MH™ and K-CAT™ are cloud-based and can be administered on any internet-capable device (smartphone, tablet, notebook, or computer). Our tools are scalable to any size population via a HIPAA secure Amazon Web Services (AWS) platform.

NIMH: Adaptive Screener (CASSY) May Help Identify Youth at Risk of Suicide

“The screener, called the computerized adaptive screen for suicidal youth (CASSY), consists of 11 questions on average and correctly identified 82.4% of youth who went on to attempt suicide in the three months following screening. The results suggest this screener could serve as an easy-to-use way for providers to detect youth suicide risk in emergency department settings.”

The Millennium Institute for Research on Depression and Personality (MIDAP) and the MIDE UC Measurement Center begin their scientific-academic collaboration by organizing an international seminar to address the issue of routine measurement in the provision of mental health services. Dr. Gibbons discusses the CAT-MH™ and its advances in mental health measurement. Dr. Alegria discusses cross-cultural studies in the assessment of mental health.

Effect of the Wingman-Connect Upstream Suicide Prevention Program for Air Force Personnel in Training: A Cluster Randomized Clinical Trial

“Wingman-Connect is the first universal prevention program to reduce suicidal ideation and depression in a general Air Force population. The primary outcomes were scores on the suicidal ideation and depression scales of the CAT-MH™ and self-reports of military occupational impairment. Reduced depression symptoms were maintained through 6 months, and the odds of having elevated depression symptoms were lower (odds ratio, 0.80) at either follow-up point.”
