Health Belief Model

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.

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.

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.

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.
