Intensive Longitudinal Data Analysis

Intensive Longitudinal Data Analysis: 

The amount of data that can be collected using Ambulatory Assessment (AA) methods is exponentially larger than what many psychological scientists are used to managing. AA data are often collected over much of the 24-hour day and over many days. In some of our studies, participants contribute over 10,000 data points per day. Therefore, expert data management and expertise in quantitative methods appropriate for “big data” like these are needed. Our lab has published several papers proposing unique approaches to analyzing data for these types of studies. For example, our papers have focused on conceptualizing and quantifying dynamic processes like affective instability, impulsivity, and undifferentiated negative affect. For the research described above, Dr. Trull played critical roles in all aspects of the research (i.e., study planning, obtaining funding, framing the research question, data analytic approach, and ms preparation).
