Detailed Description
-----------------
İntroduction Breast cancer; It is an important public health problem because it is the most common cancer type globally and is closely associated with mortality. Breast cancer, which is a chronic disease and continues throughout life; It negatively affects many aspects of life with its individual, familial and social dimensions. Due to both the disease and a long and difficult treatment process, many individual and social changes are experienced in the process after the active treatment of breast cancer is completed, physical discomforts such as fatigue and pain continue, and many problems such as fear of recurrence of the disease and changes in body image occur in life quality and well-being are significantly affected. In addition, in this process, patients; They may experience many problems such as permanent side effects of the treatment, stress and depression, and they need to be informed about lifestyle changes. Despite that; When the literature is examined, while the problems of cancer patients during the treatment process are considered more important, they are not given enough attention after the treatment process and there are limited number of studies on the problems experienced in this period. At this point, studies based on the Health Promotion Model, which include the processes of acquiring health promoting behaviors in detail and which is one of the most widely used models in nursing research, are of great importance. According to the literature, healthy lifestyle behaviors prevent late problems, chronic disease risks, recurrences, secondary cancers and reduce mortality in cancer patients; on the other hand, it is stated that it increases individual coping and quality of life, supports the individual holistically, and reduces health expenditures. One of the most used integrative/holistic applications in cancer patients today is guided imagery. In addition to contributing to the development of targeted behavior, guided imagery; by making the patient's mind get away from disturbing emotions and negative thoughts in daily life and feel relaxed, happy and peaceful; positively affects well-being, self-efficacy and quality of life. As it is known, the quality of life is one of the United Nations Sustainable Development Goals and is considered internationally important. When the literature is examined, guided imagery has been applied in cancer patients, especially for the management of symptoms such as pain, fatigue, nausea-vomiting, insomnia, stress and anxiety, in individuals whose treatment process is ongoing. No study was found that evaluated the simultaneous effects of the health promotion model and guided imagery. A guided imagery method that positively supports individuals' well-being and quality of life by providing mind-body harmony. Keywords: Breast Cancer, Health Promotion Model, Guided Imagery, Nursing, Quality of Life, Healthy Lifestyle Behaviors Research Hypotheses H1a: After the training and counseling supported guided imagery application based on the health promotion model in the experimental group, the healthy lifestyle behaviors mean scores of the participants were higher than before the application (within group) and control group (between groups). H1b: After the training and counseling supported guided imagery application based on the health promotion model in the experimental group, the health-related quality of life score averages of the participants were higher than before the application (within group) and control group (between groups). This research is a randomized controlled experimental study aiming to evaluate the effect of education and counseling supported guided imagery application based on the health promotion model in breast cancer patients on healthy lifestyle behaviors and quality of life. Research; It will be carried out between 01 February 2022 and 01 February 2023 with individuals diagnosed with breast cancer who have completed the treatment process and reside in Erzurum city center, registered in the Medical Oncology Polyclinic of Atatürk University Health Research and Application Center. Population and Sample of the Research The universe of the research; consists of individuals with breast cancer who have completed the treatment process and reside in Erzurum city center and are registered to the relevant oncology outpatient clinic (N=291). The sample number is; Similar studies in the G*Power 3.1 program were calculated as, taking into account 50% effect size, 95% reliability and 95% theoretical power. However, it was determined that 70 people would be included in the study by adding 16 people (30% more than the sample number) to the determined sample, in case the participants could withdraw from the study at any stage of the research. The systematic sampling method was used to determine the 70 people to be sampled. The women selected from the list by systematic sampling method were called by phone, informed about the research and invited to the research. Those who agreed to participate in the study were included in the sample after obtaining their verbal consent from those who met the inclusion criteria. If the sample size could not be reached due to reasons such as the criteria were not met or the research invitation was not accepted, the systematic sampling method was repeated within the same list until the targeted sample size was reached. In the pre-test phase of the research, two people left the study voluntarily. For this reason, randomization was made with 68 people. A simple randomization method was used in order to assign people included in the study to the experimental and control groups in an unbiased manner. Randomization was done in computer environment using https://www.random.org/ website. The women in the experimental and control groups were determined according to the order obtained. In this way, 34 individuals were included in the experimental group and 34 individuals in the control group. After randomization, the homogeneity of the groups according to the control variables was evaluated and the groups were found to be homogeneous. Variables of the Study Dependent variables: Healthy lifestyle behaviors, quality of life. Independent variables: Guided imagery practice, training and counseling program. Control variables: Age, education level, childbearing status, time of diagnosis of disease, clinical stage diagnosed, treatment completed. Data Collection Tools In the collection of research data; Introductory Information Form, Healthy Lifestyle Behaviors Scale II and SF-36 Quality of Life Scale will be used. In addition, the Body Mass Index (BMI) of all participants will be evaluated. In the research, the Feedback Form on the Research Process will be applied to all participants. Data Collection Pre-test and post-test data of the research; After obtaining written consent from the individuals included in the study, it was collected face-to-face by an interviewer who was pursuing his graduate education in public health nursing and was trained in the research process and data collection process. In the data collection process, double-blindness was ensured by not telling the interviewer from which group the data was collected and which group they were in. Pre-Test Data Collection Experiment and control groups in the pre-test; Introductory Information Form, Healthy Lifestyle Behaviors Scale II and SF-36 Quality of Life Scale were applied and BMI Evaluation was made. Data collection took an average of 45 minutes for each individual, and the data were collected face-to-face by the interviewer during a home visit. Pre-test data were collected between 04 April 2022 and 23 May 2022. Collection of Post-Test Data After the training and counseling supported guided imagery application based on the health promotion model was completed, in the collection of post-test data, individuals in the experimental and control groups; Healthy Lifestyle Behaviors Scale II and SF-36 Quality of Life Scale will be applied and BMI Assessment has been made. In addition, the participants in the experimental group regarding the research process were evaluated with the Research Process Feedback Form. Data collection took an average of 45 minutes for each individual. The data were collected face-to-face by the interviewer during a home visit. It is planned to collect post-test data between 22 August and 15 September 2022. Pilot Application In the research; A pilot study was conducted on five patients who had the same characteristics as the sample group but who would not be included in the main study. Nursing Interventions As a nursing initiative to the experimental group in the research; Training and consultancy supported guided imagery application based on the health promotion model was applied. Before starting any intervention, pre-test measurements of 68 individuals in the experimental and control groups were made. After the pre-test data were collected, the individuals in the experimental group were visited by the researcher at their homes; One training booklet, Mp3 player with guided imagery recording, pilates band and 0.5 kg dumbbells were delivered. Two WhatsApp groups were created separately for the experimental and control groups, and the participants were added to these groups. In addition, an e-mail address was provided to the participants. To provide an additional option for the participants regarding the accessibility of the initiative materials and to increase their permanence; The training booklet and the guided imagery recording were also sent to the individuals in the experimental group via WhatsApp to their phones and e-mails. Then, a Google Meet record was created for each participant. Information was given on how to use the application and how to enter the link sent via WhatsApp and e-mail. Internet support will be provided by the researcher to individuals who have internet connection problems during the research process, and this situation will be taken into account in arranging the session hours. After the preparation process, as a nursing attempt to the individuals in the experimental group; Training and consultancy supported guided imagery based on the health promotion model will be implemented. This initiative; It will take a total of 12 weeks, including 6 weeks of training program and 6 weeks of counseling program and guided imagery. After the application is completed, the post-test measurements of the individuals in the experimental and control groups will be made. No attempt will be made to the individuals in the control group during the research process. After the research process is completed, a training booklet, Mp3 player loaded with guided imagery recording, pilates tape and 0.5 kg dumbbells will be delivered to the individuals in the control group; The training booklet and the guided imagery recording will also be sent to WhatsApp and e-mails. Then the same intervention applied to the experimental group will be applied. Educational program: The content of the training program was prepared by scanning the national and international literature and taking the opinions of four experts.

The counseling program will be carried out individually, and within this scope, three Google Meet meetings will be held with each participant in total. These interviews last approximately 30-45 minutes. it will last. With the counseling program, reminders will be made about performing and maintaining healthy lifestyle behaviors and guided imagery to increase the quality of life of breast cancer patients, their questions will be answered, counseling will be given and follow-up will be made in line with their needs and based on the sub-components of the health promotion model. Guided Imagery Application: In the research, guided imagery scenario content including positive directives for healthy lifestyle behaviors and quality of life was created with the support of the literature. The script content was written by Dr., who is an expert in clinical psychology and also took part in the research process as a second consultant. Instructor Prepared under the supervision of member Derya Gürcan Yıldırım. For the guided imagery scenario content prepared, expert opinions were received from 10 people from the fields of Psychiatric Nursing, Mental Health and Diseases and Clinical Psychology. Scenario content after expert opinions; It was voiced by the researcher with a musical accompaniment of relaxing, relaxing, soft and slow tempo mixed nature sounds and recorded with a voice recorder. Then the created recording was transferred to Mp3 players by the researcher. Mp3 players with guided imagery recordings were delivered to the individuals in the experimental group by the researcher after the pre-test data were collected and they were informed about their use. Before starting the guided imagery application, the individuals in the experimental group will be told how to apply the guided imagery in the sixth week of the training program and explanations will be given before the application. In the first three days, the guided imagery application will be divided into four groups of 7 people and one of 6 people in the experimental group, divided into five groups in total by the researcher and over Google Meet. Afterwards, the participants will be given a guided imagery application in their own homes, once a day for 6 weeks, for a period of time they have determined, accompanied by an Mp3 player loaded with the guided imagery recording delivered at the beginning of the research. At the same time, participants will be asked to record the guided imagery practice daily in the checklist on the back of the training booklet delivered at the beginning of the study. Follow-up of the participants will be made with Google Meet meetings in 15-day periods within the scope of the consultancy program that will be carried out simultaneously with the guided imagery application. Evaluation of Data SPSS 22.00 package program will be used in the coding and evaluation of the data. In addition to the mean, standard deviation, numbers and percentages in the evaluation of the data, it is thought that analyzes such as t-test for independent groups, t-test for dependent groups, analysis of variance, correlation and regression analysis will be used in statistical comparisons according to the characteristics of the data. Normality distributions of the data will be evaluated with Kurtosis and Skewness coefficients, non-parametric tests will be used for data that are not normally distributed. The internal validity of the scales will be determined by the Cronbach α coefficient, and whether the descriptive features of the experimental and control groups are homogeneous will be analyzed by the chi-square test. A low p value of 0.05 will be accepted as the level of significance.
