The Intraindividual Study of Affect, Health and Interpersonal Behavior is an intensive longitudinal study that collected rich repeated measures of its namesake variables at multiple time-scales.

Participants, 150 adults (age 18-89 years, 51% women) from the Pennsylvania State University and surrounding community, completed three 3-week “measurements bursts” during which they reported on their social interactions, thoughts, feelings, and behaviors.

Innovative study design combined the use of smartphone-based and web-based assessments provided rich data on behavior that unfolds across, hours, days, months, and years. The breadth, depth, and length of the study support a wide array of substantive research and serve as a playground for methods development.
