Social Network Analysis With Ashton Verdery

October 10, 2018

In our latest podcast, Ashton Verdery, assistant professor of sociology and demography at Penn State, discusses social network analysis (SNA). One increasingly important use of SNA is to study marginalized populations who are otherwise hard to sample. In health, behavioral, and social sciences, SNA has been used to examine how people relate to one another; how relationships affect the flow of items such as diseases, goods, information, or behaviors; how individual positions in broader network structures affect the risks of contracting diseases, hearing of opportunities, or generating new ideas; and more. In this podcast, Ashton explains the value and challenges of SNA in a behavioral health context. He also discusses projects from his research, including his work studying the heroin crisis in Pennsylvania, kidney transplant candidates, and migrant populations.

“In the United States and worldwide, billions of dollars have been spent to develop behavioral, biobehavioral, and biomedical interventions (hereafter referred to simply as interventions) to prevent and treat health problems, promote health and well-being, prevent violence, improve learning, promote academic achievement, and generally improve the human condition. Numerous interventions are in use that are successful in the sense that they have demonstrated a statistically and clinically significant effect in a randomized controlled trial (RCT). However, many are less successful in terms of progress toward solving problems. In fact, after decades of research, as a society we continue to struggle with the very issues these interventions have been designed to ameliorate. Only very slow progress is being made in many areas; in some, the problem continues to worsen. Let us consider two examples in the public health domain, both from the Healthy People goals set every ten years by the United States Centers for Disease Control and Prevention (CDC)…”

Ambulatory Assessment with Michael Russell

Michael RussellJanuary 23, 2017

In our latest podcast, Methodology Center Research Associate Michael Russell discusses ambulatory assessment and his pilot project examining self-report data during heavy drinking. In the project, Michael is combining ecological momentary assessment (EMA) of self-reported alcohol use with continuous data from ankle bracelets that measure alcohol intoxication levels through contact with the skin. He is investigating the accuracy of using EMA self-reports as a proxy for such intoxication measures during real-world drinking episodes. He discusses his thoughts on the challenges and opportunities of such data collection, and talks about some of his research using these and other intensive longitudinal data (ILD).

Practical Advice on LCA with John Dziak

Aaron Wagner and John DziakDecember 1, 2016

Latent class analysis (LCA) is a widely used tool for identifying subgroups in a population. Many researchers have questions about how to conduct an LCA as responsibly and accurately as possible. In our latest podcast, John Dziak discusses important points to consider when conducting an LCA, like how to tell when an analysis is successful and how to make sure your model is properly identified. John is a Methodology Center research associate who studies LCA, and he is the lead developer of our LCA software, including PROC LCA. Note: this podcast is a companion piece to podcasts 15 and 16 with Stephanie Lanza and Bethany Bray. If you are new to LCA, you may want to start with Podcast 15.

Using MOST to Improve STI Prevention with Kari Kugler and Amanda Tanner

Kari Kugler and Amanda TannerJanuary 27, 2016

In this podcast, we discuss the application of the multiphase optimization strategy (MOST) to the development of an online intervention to reduce sexual risk behavior among college students. Host Aaron Wagner speaks with Kari Kugler, Methodology Center investigator, and Amanda Tanner, assistant professor of public health education at University of North Carolina at Greensboro (UNCG), about the project which is funded by the National Institute on Alcohol Abuse and Alcoholism.

In this study, the researchers will use MOST to strengthen intervention components aimed at reducing risky drinking, risky sex, and their co-occurrence, and then using the strengthened components to form an optimized intervention. The principal investigator of the project is Methodology Center Director Linda Collins. David Wyrick, associate professor of public health education, leads the team at UNCG.
