Construction of Graphical Models for Temporary Application of Facial Packs

Abstract

We constructed one physiological model and two psychological models for a set of experimental data to investigate the variation of effects among facial pack types of temporary facial pack applications. Using a Bayesian network, a physiological model was built for the transitions of skin moisture and skin surface lipids. The resultant network had direct paths from lipids measured at the forehead to moisture measured at the right cheekbone. This result suggests the existence of some indirect relation among them. Psychological models were constructed to analyze responses of the post-experiment questionnaire using structural equation modeling. One model was built for the impression of the appearance of the packs. We assumed two latent factors––security and likeability––and obtained reasonable fit indices. Another model was built for the overall impression on the experience of temporary pack application. Cronbach’s α was consistently large for a subscale that consisted of the observed variables in this model. Although fitness was bad, path coefficients were also consistently large.
