This study investigated the effects of the "Orientation Camp" upon the freshmen's adjustments and satisfactions to their new college-lives. Two-hundred and sixty-seven freshmen who participated in the camp and 148 freshmen who didn't participate in it were administered questionnaires two or three times. Their scores of adjustment and satisfaction to their new lives were examined by 2 X 2 X 2 (participant/not participant of the camp, the choice order of Hiroshima University, the first/not the first and before/after the Camp) ANOVA. The scores of adjustment and satisfaction after the camp decreased as compared with before the camp. However, the scores of adjustment of the freshmen who participated the camp and whose choices were the first were higher than the scores of the other groups both before and after the camp. The scores of satisfaction of the freshmen who didn't participate and whose choices were the first decreased markedly. The results suggest that the Orientation Camp was effective only for the freshmen who willingly entered Hiroshima University to adjust to their new college-lives but not for those who reluctantly entered.
