January 14, 2013   New book by Marlos Viana is now in print
   

A new book authored by Marlos Viana, Ph.D., and Vasudevan Lakshminarayanan, Ph.D., is now in print. Dihedral Fourier Analysis introduces the theory and methods necessary to study experimental data indexed by, or associated with, dihedral symmetries such as rotations and reversals realized as vector fields or symbolic sequences. Its particular relevance as a research tool in areas such as optical and molecular biology statistics appears when formulated within the context of symmetry studies, which formally connects algebraic and statistical reasoning together in one methodology for data summary and inference.

 
 
December 21, 2012   Study published in the Journal of Consulting and Clinical Psychology
   

A study by Juned Siddique, Ph.D., C. Hendricks Brown, Ph.D., M.A., et al., was published in the December 2012 issue of the Journal of Consulting and Clinical Psychology.

The study examines whether there are latent trajectory classes in response to treatment and whether they moderate the effects of medication versus psychotherapy. The authors conclude that among depressed women with moderate baseline depression and anxiety, medication was superior to CBT at 6 months, but the difference was not sustained at 1 year. Among women with severe depression, there was no significant treatment group difference at 6 months, but CBT was superior to medication at 1 year.

These findings are presented in the article “Comparative Effectiveness of Medication Versus Cognitive-Behavioral Therapy in a Randomized Controlled Trial of Low-Income Young Minority Women With Depression” by Siddique, Juned; Chung, Joyce Y.; Brown, C. Hendricks; Miranda, Jeanne.

 
 
November 5, 2012   Study published in the Archives of General Psychiatry
   

A study led by Robert D. Gibbons, Ph.D., was published in the November 2012 issue of Archives of General Psychiatry regarding the development of a computerized adaptive test (CAT) for depression: the CAT-Depression Inventory or "CAT-DI."
* Please note that Figure 3 in the article referenced above should be replaced with this image.

The paper describes how CAT based on multidimensional item response theory can adaptively select a small targeted set of items for each individual from a much larger bank of test items. The paradigm shift is from a fixed set of items with varying measurement uncertainty to a varying number of items with fixed measurement uncertainty. The net result is a dramatic improvement over traditional mental health measurement. The CAT-DI requires an average of 12 items per patient yet maintains a correlation of r=0.95 with the entire 400 item bank. Using an empirically derived threshold, sensitivity of 0.92 and specificity of 0.88 are obtained for differentiating patients with major depressive disorder (based on systematic DSM-IV interview) versus non-psychiatric controls.

The production version of the CAT-DI and related tests for anxiety and bipolar disorder (CAT-Mental Health or CAT-MH suite of instruments) are currently under development and should be available by the end of 2012. More information about web- and Windows-based versions of the CAT-MH programs is available at Adaptive Testing Technologies.

March 26, 2012   Study published Online First by the Archives of General Psychiatry
   

A second study by Robert D. Gibbons et al. was published Online First by the Archives of General Psychiatry on March 5, 2012 as a companion study to the one published last month on the effects of antidepressant treatment on suicidal thoughts and behavior.

The study constitutes the first research synthesis in this area to use complete longitudinal person-level data from a large set of published and unpublished studies. The results do not support previous findings that antidepressants show little benefit except for severe depression. The antidepressants fluoxetine and venlafaxine are efficacious for major depressive disorder in all age groups, although more so in youths and adults compared with geriatric patients. Baseline severity was not significantly related to degree of treatment advantage over placebo.

These findings are presented in the article “Benefits From Antidepressants: Synthesis of 6-Week Patient-Level Outcomes From Double-blind Placebo-Controlled Randomized Trials of Fluoxetine and Venlafaxine” by Robert D. Gibbons, Ph.D., Kwan Hur, Ph.D., C. Hendricks Brown, Ph.D., John M. Davis, M.D., and J. John Mann, M.D.

February 6, 2012   Robert D. Gibbons interviewed by U.S. News & World Report
   

Robert D. Gibbons was interviewed by U.S. News & World Report about a recent study by Gibbons et al., published Online First by the Archives of General Psychiatry on February 6, 2012.

The study found that antidepressant drugs such as fluoxetine and venlafaxine decreased suicidal thoughts and behavior for adult and geriatric patients. For youths, no significant effects of treatment on suicidal thoughts and behavior were found, although depression responded to treatment. No evidence of increased suicide risk was observed in youths receiving active medication.

These findings are presented in the article “Suicidal Thoughts and Behavior With Antidepressant Treatment: Reanalysis of the Randomized Placebo-Controlled Studies of Fluoxetine and Venlafaxine” by Robert D. Gibbons, Ph.D., C. Hendricks Brown, Ph.D., Kwan Hur, Ph.D., John M. Davis, M.D., and J. John Mann, M.D.

July 1, 2007  

Study shows decline in suicide attempts with antidepressant treatment

   

A study of 226,866 veterans diagnosed with depression during 2003-2004 determined that the number of suicide attempts declined once treatment began, and that the rate of suicide attempts was lower in depressed veterans who took antidepressants than in those who did not.

The study is described in the “Relationship Between Antidepressants and Suicide Attempts: An Analysis of the Veterans Health Administration Data Sets” article by Robert D. Gibbons, Ph.D., C. Hendricks Brown, Ph.D., Kwan Hur, Ph.D., Sue M. Marcus, Ph.D., Dulal K. Bhaumik, Ph.D. and J. John Mann, M.D.

The article appears in the July 2007 issue of The American Journal of Psychiatry, the official journal of the American Psychiatric Association (read the News Release View PDF).

November 1, 2006   Study links higher county-level antidepressant prescription rates to lower early adolescent suicide rates
   

A county-by-county study of the entire United States found that suicide rates among children ages 5-14 during the period 1996-1998 were lower in counties with higher numbers of antidepressant pills prescribed per person.

These findings are presented in the article "The Relationship Between Antidepressant Prescription Rates and Rate of Early Adolescent Suicide" View PDF by Robert D. Gibbons, Ph.D., Kwan Hur, Ph.D., Dulal K. Bhaumik, Ph.D., and J. John Mann, M.D., of the Center for Health Statistics, University of Illinois at Chicago, and the New York State Psychiatric Institute and Columbia University College of Physicians and Surgeons.

The article appears in the November 2006 issue of The American Journal of Psychiatry, the official journal of the American Psychiatric Association (read the News Release View PDF).

In this same issue, Dr. Gregory E. Simon, M.D., M.P.H., of the Group Health's Center for Health Studies compares the study's findings to those of other randomized trials and large observational studies in the editorial "How Can We Know Whether Antidepressants Increase Suicide Risk?" View PDF

     
 
September 25, 2006   The Institute of Medicine reviews the U.S. Drug Safety System
   

June 2005 marked the first meeting of a committee of academic and industry experts appointed by the Institute of Medicine to review the activities conducted by the U.S. Food and Drug Administration and to make recommendations to improve risk assessment, surveillance and the safe use of drugs.

Fifteen months later, the Assessment of the U.S. Drug Safety System committee, which includes Dr. Robert D. Gibbons, has published its findings and recommendations in its report released on September 22, 2006: The Future of Drug Safety: Promoting and Protecting the Health of the Public.

Read about the report's likelihood to intensify the debate over the current state of the U.S. federal system in charge of approving and regulating drugs and the proposed reforms of the F.D.A. in the New York Times article: Study Condemns F.D.A.'s Handling of Drug Safety (free registration required).

     
 
September 18, 2006   NIMH Awards Five-Year $3M Competitive Renewal for Gibbons CAT Grant
   

NIMH awarded a five-year, $3 million competitive renewal of the Mental Health Computerized Adaptive Testing Grant to Robert D. Gibbons, Ph.D. The aim of the investigation is to develop and evaluate computerized adaptive testing programs and algorithms for assessing depression.

The original study demonstrated the feasibility of item response theory (IRT), and computerized adaptive testing (CAT) in the development and administration of a large mental health rating scale. Using an item bank of 626 mood and anxiety disorder symptom items, the investigators found that 90% of the items in the item bank were discriminating of high and low levels of mood disorders, and the bi-factor IRT model did an excellent job of accounting for the clustering of items within symptom domains.

The initial study also found that CAT administration of the test resulted in a 95% reduction in the number of items administered to an individual subject (24 out of 626 items using simulated CAT and 31 items for live CAT testing), and the correlation between the CAT based impairment rating and the score based on all 626 items was r=0.93. Based on these results, the competitive renewal proposes to use IRT and CAT to develop a CAT Depression Inventory (CAT-DI).
