Potentials of Just in time Adaptive Interventions (JITAIs) to support health behavior changes
Ambulatory Assessment and Experience Sampling allow the real-time collection of objective sensor data and subjective data about a person's state of mind, body and context in everyday life. When combined, they provide greater insights for researchers interested in participant behaviour, using physiological data as a trigger to obtain context data via a questionnaire. This Interactive Ambulatory Assessment increases the precision of data acquisition, allowing the capture of contextual data after a specific event occurs. However, when the researcher wants to change an existing behavior, they’ll need to implement Just In Time Adaptive Interventions.
Just in Time Adaptive Interventions (JITAI) is an intervention design providing long-term support (e.g., type, timing, intensity) to a person's changing status and context, with the goal of delivering help at the time and in the context when the person needs it the most. For example, the proposed intervention may depend on whether the person is currently at work or engaged in a leisure activity. Elements of affective computing can also adapt the intervention to a person's emotional state.
Examining real time detection of behavior, either via physiological sensors or other contextual data, allows researchers to interact with participants and implement behavioral modification strategies. By coupling multiple data sources and performing real time analysis on the data acquired, movisens allows researchers to assess the effectiveness of various approaches to behavioural change.
Integrated systems for Interactive Ambulatory Assessment also allow queries to be triggered on a smartphone by events measured by a physiological sensor. For example, in studies using HRV as a proxy for stress, an ECG sensor allows the delivery of queries about the participant’s subjective state when a defined change in heart rate and/or heart rate variability occurs. The researcher can define the conditions to deliver a questionnaire or intervention, or multiple or cascading conditions. When triggering a questionnaire to ask the participant for more information, we refer to this as Interactive Ambulatory Assessment, and when it triggers an intervention it’s a JITAI.
The real time analysis of data enables the person to implement a previously learned behavior for stress management or stress reduction, and that allows researchers to examine the effectiveness of such interventions.
movisens leads the way in JITAI, being the only company providing both research grade sensors and a class leading Experience Sampling platform capable of interacting with each other. In our upcoming webinar we’ll show you how to use our technological developments to implement your JITAI study easily!
We're honored by two outstanding Guest speakers - Jillian Angela Johnson from Penn State University will talk about her research on Just-in-Time Interventions on Everyday Stress to promote positive Sleep and Physical Activity Engagement. Our second Guest Speaker is Elena Koch from the Karlsruhe Institute of Technology (KIT) - She will report on her experiences using mobile-health approaches to provide video-based exercise and real-time feedback.
We look forward to virtually see you all on March 2nd at 6pm :)
