A study was conducted to investigate the relationships of intolerance for waiting-stress with health and personality. Intolerance for waiting-stress was defined as "intolerance of being kept waiting", which may be common in a society with a very fast pace of life. one-hundred and thirty students, made up of 46 males and 84 females, participated in a research towards its first objective, while another 125 students, made up of 37 males and 88 females, participated in another research towards the second objective. A five-point scale of intolerance for waiting-stress was developed and factor-analyzed. The internal consistency of this scale was confirmed. Health and personality measures were obtained by making use of the Cornell Medical Index and the Japanese version of the Guilford Personality Inventory. The correlation coefficients between intolerance for waiting-stress and the health and personality measures were low but generally significant. Higher intolerance for waiting-stress was associated with a greater prominence of physical and psychological symptoms and with maladjustive personality.
