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.



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.



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



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.


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.


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.


The CAT-MH™ has been used for
state-wide assessment of mental health disorders in the child welfare system where over 300 caseworkers have been trained in its use.


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.


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 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.

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.


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. 


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.


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.

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.


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.
