In this study, it is planned to determine the effect of acupressure applied to adolescents with primary dysmenorrhea on pain, menstrual symptoms and general comfort. The research questions of the research are as follows; Research Questions

• Is there a difference in pain scores in the post-acupressure intervention group and the placebo group?
• Is there a difference between menstrual symptoms scores in the post-acupressure intervention group and the placebo group?
• Is there a difference between comfort scores in the intervention group and the placebo group after acupressure?
• Is there a difference between the pain scores of the intervention group according to time?
• Is there a difference between the menstrual symptoms scores of the intervention group according to time?
• Is there a difference between the comfort scores of the intervention group according to time? Is there a difference between the pain scores of the placebo group over time? Is there a difference between the menstrual symptoms scores of the placebo group over time?
• Is there a difference between the comfort scores of the placebo group over time?

Methods:

Adolescents aged 14-17 years with primary dysmenorrhea will be randomly assigned to the acupressure and control groups. The study group (n=26) and placebo group (n=26) will be applied to the determined points in a certain order. The order of application is Hegu (LI4), Zusanli (ST36), Sanyinjiao (SP6). Acupressure will be applied to the adolescents in the groups individually for 18-20 minutes, twice a day in the first three days of their menstrual periods. The primary outcome measures of the study is the effect of acupressure on adolescent pain severity and menstrual symptoms. The secondary outcome measures of the study is the effect of acupressure on general comfort. Data collection forms will be applied four times in total for the second and third cycles, before and immediately after the acupressure application.

Adolescents who agreed to participate in the study by signing the voluntary consent form after being informed about the study will be assigned to the study or placebo groups by matching the numbers on the envelope according to their school numbers. In the study, a researcher will determine the acupressure and placebo points to be applied in adolescents and this researcher will make the first cycle application. Therefore, the researcher cannot be blinded. However, the participants will practice and be blinded without knowing whether the points to be treated are the acupressure point or the placebo point. Thus, the research will be carried out as a single-blind randomized controlled trial. When the research is completed, the data of the control and study groups (coded as A or B) will be transferred to the computer environment by a researcher independent of the research, and the data will be analyzed by a statistician and the findings will be reported.
