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.

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.
