Test anxiety is a condition in which people experience extreme distress and anxiety before and in test situations. It affects up to 40 percent of all students. Conventional treatment includes both medication and psychotherapy, but studies also demonstrated that placebos affect anxiety symptoms. Although in the traditional understanding placebos need to be administered in a concealed way, intriguing new studies report that open-label placebos can be effective. Since prescription of fake pills involves ethical problems, open-label placebos may provide important new treatment possibilities. Here we report results of a pilot study examining whether open-label placebos may reduce test anxiety and improve self-management skills. 58 students participated in a two-group randomized controlled trial. Two weeks before an exam at the university participants received open-label placebos or no pills (control group). Participant - provider relationship and amount of contact time was held similar for all groups. After two weeks we found that test anxiety and self-management abilities (skills and resources) of the open-label placebo group were more improved than in the control group. Thus, our results seems to indicate that open-label placebos may reduce test anxiety and enhance self-management skills in students.
