A group of students attending the University of Texas at Austin were first given an initial diagnostic and then given a score between 1 and 5 based on their potential to have claustrophobia. Those who scored a 3 or higher were used in the study. The students were then asked how well they felt they could cope if forced to stay in a small chamber for an extended period of time. Concerns expressed in the questions asked were separated into suffocation concerns and entrapment concerns in order to distinguish between the two perceived causes of claustrophobia. The results of this study showed that the majority of students feared entrapment far more than suffocation. Because of this difference in type of fear, it can yet again be asserted that there is a clear difference in these two symptoms.
