Gastroenterology & Endoscopy News: IBD Linked to Depression and Anxiety
“Clinically active inflammatory bowel disease is positively correlated with symptoms of depression and anxiety, researchers have found. Previous studies proposed a relationship between depression, anxiety and IBD, but its directionality and causality remain unknown. For the new study, researchers at a tertiary IBD clinic screened consecutive patients for depression and anxiety using the validated Computerized Adaptive Test for Mental Health (CAT-MH), a novel computerized testing technology in which patients used a smart device to take a short test that adapted in length and content based on their previous answers.”
Exploring Key Policy Challenges and Opportunities to Improve Care for People with Mental Health and Substance Use Disorders
“Individuals with mental health and substance use disorders, particularly those with the most serious conditions, face substantial obstacles to receiving effective, evidence-based care. Despite their high rates of co-occurrence with other medical conditions, the integration of services for mental health and substance use disorders into the broader health care delivery and financing system has proved challenging. The Forum’s initial workshop will take a broad approach to examine several related overarching topics.”

Without Wasting a Word: Extreme Improvements in Efficiency and Accuracy Using Computerized Adaptive Testing for Mental Health Disorders (CAT-MH™)
Adaptive tests for a wide variety of mental health traits (e.g., depression, anxiety, mania, substance misuse, suicidality) are now available in a cloud-based environment. These tests have been validated in a variety of settings against lengthy structured clinical interviews with excellent results and even higher reliability than fixed-length tests. Adaptive tests, easily integrated into electronic health records, will provide increased precision of measurement and decreased burden of measurement.
An Inflammatory Profile Linked to Increased Suicide Risk
Suicide risk assessments are often challenging for clinicians, and therefore, biological markers are warranted as guiding tools in these assessments. Suicidal patients display increased cytokine levels in peripheral blood, although the composite inflammatory profile in the subjects is still unknown.To address this, we measured 45 immunobiological factors in peripheral blood and identified the biological profiles associated with cross-diagnostic suicide risk and depression, respectively. A unique immunobiological profile was linked to increased suicide risk. The profile was different from that observed in patients with depressive symptoms, and indicates that granulocyte mediated biological mechanisms could be activated in patients at risk for suicide.
Depression in Emergency Department Patients and Association with Health Care Utilization
We sought to estimate the rate of severity of major depressive disorder (MDD) in a nonpsychiatric ED population and its association with subsequent ED visits and hospitalizations. Standardized assessment tools that provide rapid, accurate, and precise classification of MDD severity have the potential to play an important role in identifying ED patients in need of urgent psychiatric resource referral.
Validation of the Computerized Adaptive Test for Mental Health in Primary Care
The US Preventive Services Task Force recommends screening for depression in the general adult population. Although screening questionnaires for depression and anxiety exist in primary care settings, electronic health tools such as computerized adaptive tests based on item response theory can advance screening practices. This study evaluated the validity of the CAT-MH™ for screening for MDD and assessing MDD and anxiety severity among adult primary care patients.
Researchers at UCLA are Leveraging the CAT-MH™ as an Important Tool in their Fight Against Depression
Fox News reports on UCLA launching an ambitious new program to cure depression. Using a mobile interface form of CAT-MH™, researchers hope to identify the genetic, cognitive, and environmental factors associated with depression by surveying 100,000 volunteers. These volunteers will be encouraged to participate over a long period of time to better understand the root causes of depression. UCLA’s approach marks the first time there has been a campus-wide effort to eradicate a disease.
In a Fight Against Depression, UCLA Relies on Technology
In what amounts to a research moonshot, the University of California at Los Angeles aims to “cut the burden of depression in half” by 2050 and to eliminate it by the end of the century. In a study conducted since last year as part of the Depression Grand Challenge — an interdisciplinary research project that adopts the popular “grand challenge” format to solve major social or scientific problems — UCLA researchers have used an online program to measure the anxiety and depression levels of nearly 4,000 students.
High-Frequency Measurement of Depressive Severity in a Patient Treated for Severe Treatment-Resistant Depression with Deep Brain Stimulation
We present, to our knowledge, the first example of high-frequency depressive severity measurement-based DBS treatment in particular and psychiatric treatment in general. We demonstrated the feasibility of daily depressive severity measurement at high levels of precision and compliance. Clinician ratings confirm the general pattern of treatment benefit, but mask the marked variability in mood and more marked periods of benefit and decline.
Development of a Computerized Adaptive Test Suicide Scale – The CAT-SS
For this study, a psychometric harmonization between related suicide, depression, and anxiety symptom domains that provides a more balanced and complete spectrum of suicidal symptomatology was developed. The objective of this article is to describe the results of the early stages of computerized adaptive testing development for a suicide scale and pave the way for the final stage of validation. The CAT-SS is able to accurately measure the latent suicide dimension with a mean of 10 items in approximately 2 minutes.

Archives of Women’s Mental Health: The Experience of Depression, Anxiety, and Mania among Perinatal Women
We assessed differential item functioning (DIF) based on computerized adaptive testing (CAT) to examine how perinatal mood disorders differ from adult psychiatric disorders. The CAT-Mental Health (CAT-MH™) was administered to 1614 adult psychiatric outpatients and 419 perinatal women. There was little evidence of DIF for depression and anxiety symptoms in perinatal women. This was not true for mania. Now calibrated for perinatal women, the CAT-MH™ can be evaluated for longitudinal symptom monitoring.
