Presenters: Rosalie Liccardo Pacula, PhD, and Rosanna Smart, PhD
Monday November 16th, 2020 from 12 – 1:30 PM EST
ABSTRACT: Numerous private and public agencies are collecting and reporting out information on state opioid policies to facilitate greater analysis and dissemination of state approaches for tackling the opioid epidemic. Most agencies focus on laws/statutes, which means that this is where the bulk of the research is happening. Definitions of many policies differ across some of the most commonly relied upon sources, which contributes to uncertainty regarding their impact. In this workshop, we will discuss some of the most common definitions being used for various policies, discuss how differences in assumptions regarding the meaning of “effective date” can have important implications regarding the likelihood of finding an impact through analysis, and discuss the importance of considering multiple policy domains.
Methods Workshop: State-Level Opioid Policy Analyses: Moving Beyond the Classic Difference-in-Difference Model

Presenters: Megan Schuler, PhD, and Beth Ann Griffin, PhD
Monday December 14th, 2020 from 12 – 1:30 PM EST
ABSTRACT: Motivated by the context of opioid policy research, this workshop will provide an overview of key methodological challenges faced when evaluating the effectiveness of state-level policy using annual state- level data, as well as potential solutions and practice guidelines. We will begin discussing the commonly used linear difference-in-difference (DID) model and then subsequently discuss DID extensions and alternative approaches (i.e., autoregressive models, non-linear models, doubly robust methods, synthetic controls). Methods will be demonstrated in STATA using an opioid policy case study.
Conducting Economic Evaluations Alongside Substance Use Disorder Clinical Trials: Statistical Methods and Best Practices
Presenters: Ali Jalali, PhD, Kathryn E. McCollister, PhD, Sean M. Murphy, PhD
Monday January 11th, 2021 from 12-1:30 PM
ABSTRACT: This CHERISH (Center for Health Economics of Treatment Interventions for Substance Use Disorder, HCV, and HIV) sponsored seminar will provide an in-depth review of methods for conducting an economic evaluation alongside a clinical trial. Statistical methods frequently employed in applied health econometric studies (two-part, and generalized linear models, recycled predictions, mixed effects, longitudinal analysis, etc.), and best practices for data collection and analysis will be discussed, with examples using Stata statistical software; however, experience with Stata is not a prerequisite. This seminar is designed for investigators who have some familiarity with economic evaluations, but would benefit from a more detailed outline of the methods involved and examples of their application.
