The Self-Concealment Scale (SCS; Larson & Chastain, 1990) was translated and altered to apply for Japanese subjects. Introvert stimulus-seeking score of the Kida's Stimulus-Seeking Scale (KSSS) and the Japanese SCS significantly correlated with self-report bodily symptoms after controlling number of friend, number of close friend, frequency of casual conversation and extrovert Stimulus-seeking score of the KSSS (n=593). The results suggested that stress induced by active inhibition (Pennebaker, 1989) is regulated by amount of distressing and concealed experiences and accessibility to these memories.
