Opening Keynote-Susan Murphy- Stratified Micro-randomized Trials with Applications in Mobile Health
Technological advancements in the field of mobile devices and wearable sensors make it possible to deliver treatments anytime and anywhere to users like you and me. Increasingly the delivery of these treatments is triggered by detections/predictions of vulnerability and receptivity. These observations are likely to have been impacted by prior treatments. Furthermore the treatments are often designed to have an impact on users over a span of time during which subsequent treatments may be provided. Here we discuss our work on the design of a mobile health smoking cessation study in which the above two challenges arose. This work involves the use of multiple online data analysis algorithms. Online algorithms are used in the detection, for example, of physiological stress. Other algorithms are used to forecast at each vulnerable time, the remaining number of vulnerable times in the day. These algorithms are then inputs into a randomization algorithm that ensures that each user is randomized to each treatment an appropriate number of times per day. We develop the stratified micro-randomized trial which involves not only the randomization algorithm but a precise statement of the meaning of the treatment effects and the primary scientific hypotheses along with primary analyses and sample size calculations. Considerations of causal inference and potential causal bias incurred by inappropriate data analyses play a large role throughout.

Peter Molenaar- Alternative forms of Granger causality, heterogeneity
Alternative forms of Granger causality based on standard vector autoregressive (VAR), structural VAR and unified structural equation models are presented, including time-frequency domain extensions. The group iterative multiple model estimation (GIMME) approach is proposed as the best method to accommodate heterogeneity and avoid limitations of structural VAR modeling. A new type of VAR – hybrid VAR – is introduced to obtain a unique data-driven solution to Granger causality testing.

Tenko Raykov- Item Response Theory and Classical Test Theory: Too Long Too Far
This talk is concerned with a view of item response theory that is inclusive of classical test theory rather than juxtaposing the former to the latter. In the widely employed setting in empirical research of homogeneous binary or binary scored items with no guessing, popular item response theory models can be directly obtained from appropriately developed classical test theory based models accounting for the discrete nature of the observed items. Two distinct (observational) equivalency approaches are pointed out that render these item response theory models from corresponding classical test theory based models, and can each be used to obtain the former from the latter models. Similarly, classical test theory based models can be furnished utilizing the reverse application of either of those approaches from corresponding item response theory models.

Item Response Theory from a Latent Variable Modeling framework- Tenko Raykov
- Coffee, continental breakfast 8:30 AM – 9:00 AM
- 9:00 AM – 5:00 PM in Laurel Hall
This one-day workshop is based on a latent variable modeling approach to item response theory (IRT) and item response modeling (IRM). The workshop commences with a non-traditional approach to IRT and IRM that is based on their essential connections to other behavioral measurement methodologies. These include classical test theory (CTT), (nonlinear) factor analysis, and logistic regression. The flaws of earlier treatments of CTT in the context of multiple IRT and IRM discussions are pointed out, which in addition to misrepresenting CTT effectively shift away research attention to more specific rather than more generally applicable modeling and analytic procedures. Resent research on the connections between classical test theory and IRT/IRM is then reviewed. Using a measurement invariance examination based approach, a multiple testing method for differential item functioning is discussed that deals with limitations of an existing widely utilized procedure. A readily applicable method for studying essential unidimensionality of multi-item measuring instruments is then obtained as a byproduct of this method. Item response models with covariates are finally discussed. Use of the popular software Mplus and Stata is made repeatedly and on a few occasions IRTPRO, flexMIRT, and R are utilized. The workshop is based on an integrative approach to measurement in the behavioral and social sciences and emphasizes throughout the links between IRT and IRM on the one hand and other measurement and modeling methodologies related to them on the other hand.
