Applications are being accepted for our five-day training on optimization of behavioral and biobehavioral interventions. The training will cover the multiphase optimization strategy (MOST)factorial and fractional factorial screening experiments; and the sequential, multiple assignment, randomized trial (SMART) . Join us May 16-20, 2016, in Bethesda, Maryland. Instructors Linda M. Collins, Susan Murphy, and Daniel Almirall will be joined by a variety of presenters describing how they are optimizing interventions.


A recent article in AIDS and Behavior introduces the  multiphase optimization strategy (MOST) to HIV and AIDS researchers as a tool for optimizing multicomponent behavioral and biobehavioral interventions. The authors explain the benefits of MOST within the context of a hypothetical intervention targeting people who live with HIV/AIDS and drink alcohol at hazardous levels.

Open the article. (Journal access required.)

Host Aaron Wagner talks with Kari Kugler, Methodology Center investigator, and Amanda Tanner, assistant professor of public health education at The University of North Carolina at Greensboro. They discuss their grant, in which they are following the multiphase optimization strategy (MOST) to develop an online intervention to reduce sexual risk behavior among college students.


Susan Murphy and her team at the University of Michigan's Institute for Social Research (ISR) are developing just-in-time adaptive interventions (JITAIs), which use mobile technology to deliver interventions exactly when and where they are needed. ISR published a story that explains the potential for JITAIs to improve public health.   


Question: "I am performing LCA and wondered how to test the significance of my covariates. I understand that I need a test statistic and its corresponding degrees of freedom. Can you help me get this information from my output?"


Save the Date: Summer Institute on EMA

We are pleased to announce that Josh Smyth, professor of biobehavioral health and medicine at Penn State, will present this year's Summer Institute on Innovative Methods, "Ecological Momentary Assessment (EMA): Investigating Biopsychosocial Processes in Context." The workshop will be held on Penn State's University Park Campus on July 21-22, 2016. We will begin accepting applications in late February or early March. Stay tuned!
