The Effect of Awareness Education on Breast and Cervical Cancer Screening Among Visually Impaired Women
The Effect of Awareness Education on Breast and Cervical Cancer Screening Among Visually Impaired Women
This quasi-experimental study aims to determine whether a breast and cervical cancer awareness training program can increase participation in cancer screening among women with visual impairments. The study also aims to identify barriers to screening and improve knowledge about cancer risk factors and screening methods. The main questions this study will address are:
Participants will:
Cancer is recognized as a significant public health problem both worldwide and in Türkiye; with its physical and psychosocial burden, it reduces individuals' quality of life and imposes a substantial economic burden on the healthcare system. Breast and cervical cancer are among the most common types of cancer in women, and mortality rates can be significantly reduced through early diagnosis methods. However, not all segments of society have equal opportunities to access these screening programs. Especially, individuals with disabilities face serious barriers in accessing healthcare services; this situation decreases the rate of benefiting from screening services and deepens health inequalities.
Visually impaired women are among the most disadvantaged groups due to gender norms and physical access difficulties. At this point, the nursing profession plays an important role. Nurses, through professional roles such as practitioner, educator, advocate, counselor, and case manager, contribute to ensuring equal access to healthcare services for individuals. The assessment of healthcare needs of individuals with disabilities, providing appropriate training, and increasing awareness are integral parts of nursing care.
In this context, health education programs planned by nurses for individuals with disabilities present an important opportunity to increase early diagnosis behaviors and reduce health inequalities. This project aims to evaluate the effect of breast and cervical cancer awareness training on the screening behavior of visually impaired women. In the project, the "GORSEM" (Awareness Training on Breast and Cervical Cancer for Visually Impaired Women) program, developed based on the Health Belief Model, will be implemented. The training content includes recognizing risk factors, the importance of early diagnosis, screening methods, and information on accessing primary healthcare centers. Participants will be referred to screening centers.

Research Design
This project will be conducted using a non-randomized quasi-experimental design with control groups. Participants will be divided into intervention and control groups, and the groups will be determined.
Independent Variable:
• "GORSEM" program (awareness training)
Dependent Variables:
Participants and Sample
The sample of the project will consist of visually impaired women over the age of 40, sexually active, who are members of the Turkish Association of the Visually Impaired Kadıköy Branch (intervention group) and the Six Dots Association of the Blind Şişli Branch (control group) in Istanbul. The minimum sample size determined by power analysis (G*Power 3.1) was calculated as 62 (at least 31 people in each group), and considering possible dropouts, the target is a total of 74 people. Efforts will be made to ensure that the intervention and control group samples are similar in terms of age, sexual experience, and screening history.
Inclusion criteria: Women who have only a visual impairment (congenital or acquired), can communicate, speak and understand Turkish, and voluntarily agree to participate in the study will be included.
Exclusion criteria: Women who have been diagnosed with either breast or cervical cancer, have undergone screening for at least one of these two cancer types within the last year, have never had sexual intercourse before, or are under the age of 40 will be excluded.
According to the Turkish Ministry of Health, General Directorate of Public Health, in current screenings conducted in Türkiye, within the breast cancer screening program for women, mammography is recommended every two years for women aged 40-69, and within the cervical cancer screening program, Pap smear and HPV-DNA tests are recommended every five years for women aged 30-65. Since participants will be referred by the investigators to CEDSTC centers after training to undergo mammography and Pap smear screening tests, visually impaired women over the age of 40 who have previously had sexual intercourse will be included in the study, as these two screening tests are performed in this common age group and Pap smear screening requires being sexually active.

Data Collection Method and Tools
Data will be collected by the investigators, on the day and time of the training, in the training room where the participants are present, by providing information about the research and answering questions about the research process. The Informed Consent Form will be read, and signed consent will be obtained from those who agree to sign, and verbal consent will be obtained via audio recording from those who cannot sign. Separate informed consent forms will be signed for the intervention group and the control group. Then, participants will be taken one by one to a private room, and the pre-test questions of the Descriptive Information Form, the Cancer Screening Knowledge Scale, the Cervical Cancer and Pap Smear Screening Health Belief Model Scale, and the Champion's Health Belief Model Scale for Breast Cancer Screenings will be read and the answers marked.
Descriptive Information Form The form, created by the investigators after a literature review, consists of 26 questions related to age, education level, household composition, employment status, income status, social security, disability pension status, having children, disability status, level of vision, menopausal status, smoking and alcohol use, family history of cancer, status of receiving information/counseling about screenings, and the persons from whom such information/counseling was received.
Cancer Screening Knowledge Scale The scale, developed by Öztürk and Uyar (2023), consists of 25 items and three sub-dimensions. The sub-dimensions are not specifically named. The first sub-dimension contains 10 items, the second contains 9, and the third contains 6 items. The scale is answered on a range from 1 to 3 as "1: True, 2: False, 3: I don't know." In scoring the scale, "True" answers are given 1 point, and "False" and "I don't know" answers are given 0 points. The lowest possible score is 0, and the highest is 25. Three items (items 2, 11, and 24) with negative meaning are reverse-coded when calculating the scale score. There is no cut-off point for the scale. Participants scoring 70% or more of the total score (17.5 points or more) are considered to have sufficient knowledge. The Cronbach's alpha coefficient of the scale is 0.89.
Cervical Cancer and Pap Smear Screening Health Belief Model Scale The Health Belief Model (HBM), developed by Champion for breast cancer and mammography, was adapted to cervical cancer and Pap smear testing by Güvenç et al. (2010) after Turkish validity and reliability analyses. The HBM was developed to help explain how changes occur in individuals' health behaviors. The Cervical Cancer and Pap Smear Screening Health Belief Model Scale consists of 35 items and five subscales. The Cronbach's alpha reliability coefficients of the subscales are: 0.95 for perceived susceptibility, 0.89 for perceived seriousness, 0.80 for perceived benefits and motivation, 0.71 for health motivation, and 0.88 for Pap smear barriers. The average Cronbach's alpha reliability coefficient of the scale is 0.77. Since all scores are above 0.70, the scale is considered reliable. The subscales of the HBM scale have Cronbach's alpha values of 0.968 for benefits and motivation, 0.927 for barriers, 0.921 for seriousness, 0.894 for susceptibility, and 0.854 for health motivation, indicating high reliability. The subscales are: cervical cancer susceptibility (3 items), cervical cancer health motivation (7 items), Pap smear benefits and motivation (4 items), Pap smear barriers (14 items), and cervical cancer seriousness (7 items). The scale is a 5-point Likert type, ranging from "strongly disagree" (1 point) to "strongly agree" (5 points).
Champion's Health Belief Model Scale for Breast Cancer Screenings The first form of the scale, developed by Victoria Champion in 1984 to measure beliefs about breast cancer and Breast Self-Examination (BSE), was revised in 1997 to update the dimensions related to BSE and add two new subscales related to mammography (mammography barriers and mammography benefits). In this revision, Cronbach's alpha reliability coefficients ranged from .65 to .90, and test-retest correlations ranged from .40 to .68. The Turkish adaptation was conducted by Gözüm et al. (2004). The scale includes dimensions such as "susceptibility," "seriousness," and "health motivation" related to judgments about breast cancer and general health; "barriers," "benefits," and "self-efficacy/confidence" related to BSE; and "benefits" and "barriers" related to mammography. Which dimensions of the scale are used depends on the purpose of the study and the characteristics of the study group. The scale is a 5-point Likert type.
Screening Test Attendance Form Prepared by the investigators, this form consists of a total of 4 open-ended questions (two for each cancer type) and is designed to determine, two weeks (post-test) and three months (follow-up test) after training, whether participants underwent screening, where the tests were conducted, to evaluate the results of those who had the tests, and to determine the reasons for not having the tests among those who did not. Screening results will be requested from the e-Nabız system without showing personal identification information two weeks and three months after the screening. The investigators will assist individuals who do not have an e-Nabız account or cannot log in.
