summer institute on innovative methods

Although the name has been tweaked over the years, and the principal investigator has changed, the Summer Institute on Innovative Methods workshop series has been held annually since 1996. Originally created by Linda M. Collins, and hosted by The Methodology Center at Penn State, this annual workshop series is ongoing and is now led by Bethany C. Bray and the Institute for Health Research and Policy at The University of Illinois at Chicago. This workshop series is funded, in part, by an award from the National Institute on Drug Abuse (R13 DA020334). Information about this year’s workshop and historical information about past workshops is available below.

2020-2021 Summer Institute on Innovative Methods:

Building Effective Just-in-Time Adaptive Interventions Using Micro-Randomized Trial Designs

Susan Murphy & Daniel Almirall

The 2020 Summer Institute has been postponed until October 25-26, 2021 due to COVID-19.

A just-in-time adaptive intervention (JITAI) is an emerging mobile health intervention design aiming to provide support “just-in-time”, namely, whenever and wherever support is needed. A JITAI does this via adaptation. The JITAI employs wearable sensors and other approaches to data collection to monitor ongoing information on the dynamics of an individual’s emotional, social, physical and contextual states. The adaptation occurs when this information is used to individualize the type and delivery timing of support. The adaptation in a JITAI is intended to ensure that the right type of support is provided whenever the person is (a) vulnerable and/or is in a state of opportunity, and (b) receptive, namely, able and willing to receive, process and utilize the support provided.
