The study is a randomized controlled trial. The sample will consist of 64 women aged 40-69. The study will be conducted between December 2026 and December 2027 at the Şükrüpaşa Family Health Center in Erzurum, Turkey. Data will be collected using an Informed Consent Form, the Breast Cancer Awareness Scale, the Health Belief Model Scale for Mammography, and a screening behavior assessment form.

The Effect of Health Belief Model-Based HPV Infection and Vaccination Education on University Students' Knowledge and Health Beliefs

This study aimed to examine changes in knowledge and health beliefs (perceived susceptibility, severity, benefits, and barriers) regarding HPV infection and cervical cancer among students residing in a university dormitory following a planned education program based on the HBM. RQ1: Do students' HPV knowledge levels differ across pre-education, post-education, and month-three measurements? RQ2: Do students' HPV-related health beliefs (perceived susceptibility, severity, benefits, and barriers) differ across the same time points?

ECHO-COPD: Impact of a Pharmacist-Led Health Belief Model-Based Educational Intervention Among Chronic Obstructive Pulmonary Disease Patients

Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease associated with substantial morbidity and mortality, impaired quality of life, and healthcare costs. Medication adherence and appropriate self-management are important components of COPD management; however, patients' health beliefs and perceptions may influence their adherence to treatment and engagement in recommended health behaviours. This study aims to evaluate the impact of a pharmacist-led educational intervention based on the Health Belief Model (HBM) on medication adherence, quality of life, and direct healthcare costs among patients with COPD receiving care at Buraidah Central Hospital (BCH) in Al-Qassim Region, Saudi Arabia. This study will use a quantitative, quasi-experimental pretest-posttest control-group design. Eligible COPD patients will be non-randomly assigned to either an intervention group or a control group. The intervention group will receive structured, pharmacist-led HBM-based educational sessions in addition to routine care. In contrast, the control group will receive standard care without additional education. Baseline assessments will include medication adherence using the Morisky Medication Adherence Scale-8 (MMAS-8); quality of life and health status using the COPD Assessment Test (CAT); health beliefs using a structured HBM questionnaire; and direct medical costs obtained from the hospital clinical cost centre. The educational intervention will be delivered over six months, followed by post-intervention assessment using the same outcome measures.

Dental Health State Utilities and Oral Health Beliefs in Periodontitis

This observational, cross-sectional study addresses gaps in periodontal health economics by measuring dental health state utility values (HSUVs) for periodontitis treatment. While Oral Health Related Quality of Life outcomes dominate current research, Health State Utility values are rarely measured and seldom applied . The few existing utility studies are methodologically limited. The primary aim is to measure Health state utility values for periodontal health states using direct elicitation methods ( Standard Gamble) in patients with clinically diagnosed periodontitis. The secondary aim is to examine associations between patient-elicited utility values, clinical periodontal status (CAL, PD, BoP), and psychosocial beliefs from the Health Belief Model including perceived susceptibility, severity, benefits, and barriers. Participants will complete utility tasks and Health belief model questionnaires in a single visit. By integrating preference-based utility measurement with clinical and psychosocial constructs, this study will provide essential data for cost-utility modelling of periodontal interventions and support patient-centered care.

Health Belief Model-Based Vulvar Self-Examination Education

This randomized controlled trial was conducted to evaluate the effectiveness of a Health Belief Model-based Vulvar Self-Examination (VSE) education program on women's health beliefs, vulvar health awareness, and vulvar self-examination behaviors. Vulvar diseases and symptoms are often overlooked due to insufficient awareness, stigma, and limited knowledge regarding vulvar health. Early recognition of vulvar symptoms may contribute to timely diagnosis and treatment of vulvar disorders. Participants in the intervention group received a structured Health Belief Model-based education program on vulvar self-examination, while the control group received routine information. Data were collected using participant information forms, vulvar health awareness assessments, and Health Belief Model-based scales before and after the intervention. The primary aim of the study was to improve women's awareness and health beliefs regarding vulvar self-examination. Secondary outcomes included changes in vulvar self-examination practices and vulvar health literacy. The findings of this study are expected to contribute to preventive women's health practices and early recognition of vulvar health problems.

HBM-Based Intervention on Cancer Screening

The aim of this study is to examine the effect of an intervention-consisting of a Health Belief Model-based educational session on the importance of early diagnosis and cancer screening, along with SMS-supported reminders-on the perceptions and attitudes toward cancer screening among women aged 30-70 who do not undergo regular screenings. The study will be conducted in two family centers, which will be assigned to intervention and control groups using a lottery method. The intervention group will receive a single-session group education, followed by weekly SMS reminders encouraging screening for two weeks. The control group will receive no additional intervention and will continue with standard care. Data will be collected simultaneously from both groups at three points: before the education, immediately after the education, and one month post-intervention.

The Effect of the Health Belief Model-Based Education Given to Mothers of Children Aged 9-15 on HPV Knowledge Level and Child Vaccination

This study aims to examine the effects of education provided to mothers of children aged 9-15 within the framework of the Health Belief Model on mothers' knowledge, attitudes, and behaviors about Human Papillomavirus (HPV), and their willingness to have their children vaccinated against HPV. The study, designed with a randomized controlled experimental design, will be conducted at three different Family Health Centers in Gaziantep and will consist of both experimental and control groups. Mothers in the experimental group will receive a three-session visually supported education program prepared by Yıldız USCA, while the control group will receive routine information using HPV brochures from the Ministry of Health. Data collection tools include a personal information form, an HPV knowledge scale, and an HPV Health Belief Model scale.

Health Belief Model-Based Survey on Breast Self-Examination Awareness and Practice Among Community-Dwelling Middle-Aged and Older Women

This observational study aims to evaluate the current status of breast self-examination (BSE) practices and related influencing factors among middle-aged and older women in urban communities, using the Health Belief Model (HBM) as the theoretical framework. The HBM is a well-established public health model for understanding preventive health behaviors, focusing on perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. The study will recruit community-dwelling women above approximately 40 years of age who have adequate cognitive and communication abilities. Data collection will be conducted through structured questionnaires administered during community health education activities. The survey will collect demographic information (e.g., age, occupation, education level, family history of breast cancer) and BSE-related variables, including awareness of breast cancer, perceived benefits and barriers to screening, knowledge of BSE methods, and sources of health information. The primary outcome is the prevalence of regular BSE practices among participants. Secondary outcomes include factors associated with regular BSE performance, such as age group, occupation type, education level, family history, and knowledge of BSE techniques. Logistic regression will be used to identify independent predictors of regular BSE practices. Findings from this study will help identify key gaps between awareness and practice, guide targeted community-based health education, and provide evidence for developing accessible, culturally appropriate breast cancer screening strategies in China. Ultimately, the results are expected to improve early detection rates and reduce the proportion of locally advanced breast cancer cases.
