Psychology Methods Hour: Using Growth Curve Modeling with Landmark Registration for the Analysis of Cortisol and Other Hormone Data
Nestor Lopez-Duran, Associate Professor, Associate Chair, Student Academic Affairs, Department of Psychology
Common approaches to modeling post-stress cortisol (Repeated Measures ANOVA, Growth Curve Modeling) assume limited individual variability in the timing of the responses, which can lead to incorrect interpretation of data when individual variability clusters among groups of interest. In this talk, Dr. Lopez-Duran will discuss the use of landmark registration to adjust for individual differences in the timing of cortisol responses and how this approach can also help in the simultaneous modeling of various dynamics of the cortisol response (activation intensity, duration, and recovery).
