Thirty members who were involved in the Syowa Station antarctic wintering research project for a whole year, in follow-up studies of changes in psychological states, were given the following three psychological test batteries : 1. State-Trait Anxiety Inventory (STAI) 2. Uchida-Kraepelin Psycho-diagnostic Test (U-K) 3. Tokyo Personality Inventory (TPI)All members were tested with the STAI every month. As time passed, the mean scores of both the STAI X-I and X-II showed a tendency to increase. The mean scores were especially high the second, sixth and last three months of the expedition. This seems to indicate that anxicty increased just after arrival at the Syowa Station, with both stait-anxiety and trait-anxiety increasing as time went on.The U-K was done four times during the year. A PF score of more than 10,and scores indicating a Type IV personality, were seen during the last two testings. These results suggest that as the isolation time increased, mental abnormalities became more obvious.The TPI was given five times during the year. Generally, the mean standard T Score became progressively higher each time the test was given. It was especially high at the last end of year testing. The year-end scores were high in the Rr, Lie, Hc, Hy, Ob, Pa, Hb and As scales, with the Hc and Hb scales showing a very significant increase (P<0.05).The TPI Character Analysis suggested that members became progressively depressive as time passed.Results of this psychological study indicated that although all members were initially quite psychologically stable while aboard the ship "Fuji" which brought them to the antarctic, they became increasingly anxious and irritable as time in isolation became longer. The last three months especially were found to be non-adaptive and depressive.
