The Effect of Mindfulness-based Yoga and Meditation on Some Parameters in Breast Cancer Patients

The study was conducted in a single-center, prospective (pretest-posttest-2. month follow-up), two-arm (1:1), randomized controlled experimental design. In this study, the effects of an 8-week structured mindfulness-based meditation and yoga program on stress, self-esteem, body image and sexual adjustment will be evaluated in women undergoing modified radical mastectomy. The 8-week interventions were conducted by the researcher. The researcher who performed these applications has a certificate of mindfulness meditation, yoga, breathing and movement trainer. Due to the nature of the research, the researcher is involved in the implementation of the mindfulness-based meditation and yoga program, data collection and data entry into the system. At the same time, the women in the experimental group had to be informed about the research. Therefore, researcher and participant blinding could not be performed. However, randomization was performed to prevent selection bias (1:1). The randomization process was performed by a statistical expert other than the researcher and communicated to the researcher. The participants included in the study were numbered from 1 to 41, preserving their random order in the list received from the hospital. The groups were divided into Group 1 and Group 2 by the statistician and the first group was determined as the experimental group and the second group as the control group by lottery method. The randomization table was created by making use of "http://calculatorsoup.com". Before the 8-week process started, 3 measurements were made to the participants: pre-test, post-test at the end of 8 weeks and follow-up measurement 2 months after the application.
