31 participants in the immediate-treatment group were exposed to hypnosis with suggestions intended to build academic self-efficacy and taught to use the provided suggestions. The comments provided from participants show evidence of a positive effect obtained from the use of self- hypnosis and the utilization of hypnosis as a tool. At the end of the study when the investigator contacted participants, some feedback suggested evidence of decreased stress, increased feelings of relaxation, and a greater sense of efficacy for completing tasks.
