Adaptive interventions help guide clinicians in their decisions concerning when and how treatments should be altered, but developing empirically based adaptations requires gathering the right kind of data. The sequential, multiple assignment, randomized trial is a recent innovation that can provide high-quality, experimental data for developing adaptive interventions. Recently, a group of autism researchers published the results of their SMART study in the article “Communication interventions for minimally verbal children with autism: A sequential, multiple assignment, randomized trial,” which appears in the Journal of the American Academy of Child and Adolescent Psychiatry, a top journal in child and adolescent mental health. The authors, led by Connie Kasari of UCLA, designed a project to improve spoken communication for children with autism who are minimally verbal. The study’s results show the benefit of integrating speech-generating devices (SGD) as a part of language development interventions and the potential of SMART designs for developing adaptive interventions.

As part of our annual series of one-credit courses in research methodology for Penn State graduate students, in fall 2015 we will offer, “Advanced topics in latent class analysis (LCA).” LCA is an analytic method used to identify hidden subgroups within a population based on individuals’ responses to multiple observed variables. This short course, taught by Methodology Center Investigator Bethany Bray, will build on the knowledge and skills presented in the short course, “An introduction to latent class and latent profile analysis.” Credit for that course is not a prerequisite for taking this course, but familiarity with LCA and baseline category multinomial logistic regression are prerequisites.

Michael ClevelandWe are pleased to announce this semester’s Taste of Methodology workshop on multilevel modeling (MLM) for analyzing clustered or longitudinal data. The May 5 workshop will be presented by Michael Cleveland, research assistant professor of health and human development and Methodology Center faculty affiliate.

 

MLMs are critical tools for analyzing clustered data, repeated measures data, and other forms of hierarchical data. These data could come, for example, from students who are nested within classrooms or participants who were followed for three or more observations.

 

A Taste of Methodology is a workshop series that offers Penn State faculty an overview of innovative methods over lunch. This semester’s workshop will present the concepts and applications of MLM in order to give faculty an efficient way to assess its potential for their research. 

 

January 16, 2015

If you work at Penn State, you should know that we hold monthly special interest group meetings open to all researchers and graduate students working with innovative research methods. The groups provide a forum for individuals to discuss their own research and to learn from others. This semester’s topics include analyzing complex data, mixture modeling, and causal analysis.
