Masumi Iida’s research interests span several domains of
social, health, and quantitative psychology. Her primary substantive
interest lies in understanding stress, coping, and well-being, with
emphases on dynamic processes and close relationships. Most of her
research has concentrated on understanding the determinants and
consequences of social support using a daily diary method. Her work on
social support seeks 1) to examine the situational determinants of
support provision and 2) to investigate the context and situations in
which receiving support has positive outcomes. Her research also
focuses on individuals’ responses to challenging situations by
examining daily coping mechanisms. Research in this area poses
multiple data-analytic challenges. The complexities associated with
longitudinal and dyadic data require a deep understanding of
quantitative methods designed to model statistical dependency. She has
developed skills in the use of multilevel statistical methods that
enable researchers to simultaneously model within- and between-unit
effects allowing for the study of dynamic (longitudinal) and dyadic data.
