Abstract:

Due to the wide-spread use of remote data collection devices such as smartphones and activity monitors, the collection of intensive longitudinal data (ILD), or data collected at multiple occasions over a relatively short period of time, has become increasingly common. ILD allow researchers to explore in-the-moment associations between quickly-changing subject attributes or behaviors, providing insight into the patterns and volatility/variability of behaviors within a day. Applied researchers are often interested in using ILD to model the in-the-moment associations between exposures (such as psychosocial, social and environmental risk factors or study interventions) on behavioral or health outcomes (such as self-reported stress levels or smoking cessation). This presentation will review commonly used multilevel or mixed modeling techniques for ILD including time-lagged models and the joint consideration of response mean and variation, with applications to tobacco use.
