Donna CoffmanPrevious literature has established that gang membership is associated with higher rates of drug use. In the forthcoming article, “Gang membership and substance use: Guilt as a gendered causal pathway,” in The Journal of Experimental Criminology, Methodology Center Investigator Donna Coffman and two other researchers examine whether anticipated guilt for substance use explains this association. The authors also expand the available set of methods for causal inference when assessing mediation in the presence of moderation and time-varying confounding.

Susan MurphyIn our latest podcast, Amanda Applegate interviews Susan Murphy, Methodology Center principal investigator, Herbert E. Robbins Distinguished University Professor of Statistics, research professor at the Institute for Social Research, and professor of psychiatry at the University of Michigan. The discussion focuses two topics, the sequential, multiple assignment, randomized trial (SMART), which allows scientists to develop adaptive interventions, and the just-in-time, adaptive intervention (JITAI), which uses real-time data to deliver interventions as needed via mobile devices. Susan’s MacArthur Fellowship is also discussed; the podcast was recorded before she was elected to the Institute of Medicine of the National Academies.

output graphWe are pleased to release the latest version of the TVEM (time-varying effect model) SAS macro suite (v. 2.1.1). The macros in this suite estimate the coefficient functions in TVEMs for intensive longitudinal data (longitudinal data such as ecological momentary assessments, EMA, that are characterized by more frequent measurements than traditional panel data). 
 
Traditional analytic methods assume that covariates have constant effects on a time-varying outcome. The TVEM SAS macros allow the effects of covariates to vary with time. These macros enable researchers to answer new research questions about how relationships change over time. The newest version of the software includes some minor usability improvements.

Susan MurphyWe are delighted to announce that Methodology Center Principal Investigator Susan A. Murphy has been named a member of the Institute of Medicine (IOM) of the National Academies. Susan’s record of innovation, particularly her development of the sequential, multiple assignment, randomized trial (SMART), has earned her many recent accolades, including a MacArthur Foundation “genius” award in 2013.

 

IOM is an independent, nonprofit organization. Members of the Institute seek to provide the best available evidence on matters related to health to inform decision making on medical matters by the government and public. Being named to the Institute of Medicine is a huge honor for any scientist working on public health issues. In 2011, The New York Times said, “The Institute of Medicine is the nation’s most esteemed and authoritative adviser on issues of health and medicine, and its reports can transform medical thinking around the world.”
