A Mobile App to Improve 24-Hour Movement Guideline Adherence in Preschoolers

The goal of this clinical trial is to evaluate whether a home-based mHealth intervention can improve adherence to the 24-Hour Movement Guidelines in preschool-aged children (3-4 years old) who currently meet 0 or 1 of the guidelines for physical activity, sedentary behavior, and sleep. The main questions it aims to answer are: * Can the intervention increase the proportion of children meeting all three 24-Hour Movement Guidelines (physical activity, screen-time, and sleep)? * Is the intervention feasible for parents to implement, as measured by a parent feedback survey? Researchers will compare an intervention group to a waitlist control group to assess whether the intervention leads to increased guideline adherence. Parents and Participants: * Children will wear an accelerometer to track physical activity and sleep patterns. * Parents will use a mobile app that delivers weekly lessons and behavior-related goals to encourage healthy movement behaviors in their children. * Parents will complete questionnaires on their child's movement behaviors and development at baseline, 6 weeks, and 12 weeks. * Additionally, children will undergo motor skills assessments, and parents will provide feedback on cognitive development and behavioral changes.

A Climate Change Education Program for 7th and 8th Grade Students in Istanbul Schools: Does It Improve Climate Knowledge and Health-Protective Behaviors?

Climate is the usual weather pattern of a place over a long time. Climate change means long-term shifts in climate, caused by natural processes and, above all, by human activity. Since the Industrial Revolution, factories and production have released more greenhouse gases into the air, and the planet has become warmer. These changes are a risk to public health. They harm some groups more than others: children, older adults, people with long-term illnesses, and people with fewer resources. This makes health inequalities worse, so fighting climate change is a public health issue as well as an environmental one. Young people today are more aware of climate change, which is a good chance to strengthen programs that protect and improve health. The few studies available show that climate change education for teenagers is mostly given in 7th and 8th grade. However, we do not know enough about whether this education changes behavior or improves health. This study aims to find out how a climate change education program affects teenagers' climate literacy (their understanding of climate change) and their health-protective behaviors. The study is quasi-experimental, with a control group and tests before and after the program. It will take place in two middle schools in Üsküdar, Istanbul, from September 2026 to January 2027. Participants will be 7th and 8th grade students from these schools. The sample size was calculated with the G\*Power 3.1.9.4 program. Allowing for dropouts, we plan to include 154 teenagers: 77 in the education group and 77 in the control group. Data will be collected with three tools: a Descriptive Information Form, the Climate Literacy Scale, and the Climate Change Health-Protective Behaviors Scale - Adolescent.

Community Beauty and Health Program for Older Adults: An Experiential Learning Trial

This study develops and evaluates a "Senior Beauty and Health Care" course designed to improve students' awareness, attitudes, and skills in caring for older adults' appearance and well-being. Using experiential learning and community practice, the course aims to reduce negative stereotypes and boost students' motivation and competence. A mixed-methods approach, including pretest-posttest surveys and focus group interviews, will assess the course's effectiveness and provide insights for future geriatric care education.

Health Education Model Led by Community Health Volunteers.

The goal of this intervention study is to investigate the level of knowledge, attitudes, and behaviors of students on schistosomiasis in Pemba Island. It aims to test the effectiveness of establishing a widely applicable Community Health Volunteers model in the Zanzibar region and explore the feasibility of promoting this model in other areas of Africa. This study also aims to provide valuable insights and references for global schistosomiasis prevention and control efforts.

Cervical Cancer Awareness Education to Aid Confidence and Screening upTake (ACT): A Pilot Randomised Control Trial

Cervical cancer remains a major threat to women's health and wellbeing, with the burden disproportionately concentrated in low- and middle-income countries such as Nigeria, where inadequate awareness, limited access to screening, screening-related anxiety, and other structural and sociocultural barriers contribute to low screening uptake, late presentation, and preventable mortality. Despite the urgent need to improve early detection, there remains a critical gap in culturally appropriate, co-produced interventions to address the barriers that shape cervical cancer screening behaviours. The proposed study will address this gap by piloting the feasibility and acceptability of "cervical cancer Awareness education to aid Confidence and screening upTake (ACT)" a novel, low-intensity, co-produced workshop intervention for women who are not up to date or only partially up to date with recommended cervical cancer screening. Delivered over approximately two hours, ACT is designed to increase awareness of cervical cancer and its symptoms, strengthen understanding of the consequences of delayed screening and the benefits of early detection, improve knowledge of available screening pathways, address misconceptions and screening-related anxiety, and build women's confidence and motivation to engage with screening services. In addition to assessing recruitment, retention, intervention engagement, acceptability and implementation feasibility, the study will pilot the proposed outcome measures and data collection procedures to inform a future definitive evaluation. It will also generate preliminary evidence on potential intervention mechanisms, screening-related outcomes, and approaches to assessing cost-effectiveness. Collectively, the study will establish whether ACT is feasible, acceptable and sufficiently promising to progress to a larger-scale trial evaluating its effectiveness and cost-effectiveness in improving cervical cancer screening uptake among women in Nigeria.

Gamified Approach To Burn Education

The goal of this clinical trial is to evaluate whether different educational strategies can improve knowledge acquisition regarding burn prevention and first aid among students enrolled in a community-based preparatory course. The main questions it aims to answer are: Does participation in a serious digital game improve knowledge about burn prevention and first aid compared with a traditional lecture? Researchers will compare a serious digital game with a face-to-face educational lecture to determine differences in knowledge acquisition and participant satisfaction between the two educational approaches. Participants will: Receive a brief, standardized 5-minute briefing limited to study logistics and session flow, with no burn-related educational content. Be randomized to participate in either a serious digital game or a face-to-face educational lecture; Complete knowledge assessment questionnaires prior to and after the intervention; Complete a satisfaction questionnaire; Attend a follow-up assessment two weeks after the intervention.

Mobile Prenatal Education for Expectant Fathers and Its Effects on Bonding, Stress, Breastfeeding and Marital Satisfaction

The aim of this interventional clinical trial is to assess whether a mobile-based antenatal education programme for expectant fathers has a positive effect on father-infant bonding, stress levels, and breastfeeding attitudes. The study aims to answer the following main questions: Does participation in a mobile-based prenatal education programme strengthen fathers' emotional bonds with their babies? Does the education reduce fathers' stress levels during the prenatal and postnatal periods? Does it increase the father's knowledge and supportive attitude towards breastfeeding? Researchers will compare whether there are measurable differences in attachment, stress, and breastfeeding attitudes between the intervention group (fathers receiving mobile-based education) and the control group (fathers receiving standard routine information). Participants: Will complete pre- and post-intervention questionnaires assessing attachment, stress, and breastfeeding attitudes. The intervention group will have access to a six-module mobile application covering topics such as infant care, nutrition, sleep routines, health and safety, emotional development, and daily care practices. The study will be conducted with fathers aged 19-65 who became fathers within the last month and voluntarily agreed to participate.

Supporting Just-In-Time Consent for Prenatal Screening: The INFORM Study

This clinical trial is about prenatal genetic screening. It will test an intervention to help people make decisions about screening. The intervention is a short set of information cards about screening. This intervention is for pregnant participants. They will use the intervention on their mobile phone before they see their doctor. The study has one main question: * Do participants who use the intervention feel more confident when they make a decision about screening? Researchers will compare participants who use the intervention to participants who do not. All participants will have their usual care when they visit their doctor. What will participants do? * Participants must be pregnant. They will sign up for the study before their first doctor's visit for their pregnancy. This is the visit where their doctor usually talks with them about screening. * Some participants will use the intervention before their first doctor's visit. Other participants will not use it. * All participants will talk with a researcher on the phone after their first doctor's visit. * Participants who use the intervention will answer a short survey on their phone. * A few participants who use the intervention will talk with a researcher a second time on the phone.

Evaluation of a Disability-Focused Sexual and Reproductive Health Curriculum for Health Students in Tanzania

This randomized controlled trial will evaluate the efficacy of a three-day sexual and reproductive health curriculum focused on persons with disabilities and tailored to the Tanzanian context. The intervention will be delivered to medical, nursing, and midwifery students at Muhimbili University of Health and Allied Sciences in Dar es Salaam, Tanzania. Participants will be randomized to either receive the curriculum during the initial intervention period or to a waitlist control group that will receive the curriculum approximately 12 months later. Participants will complete surveys at baseline and at 3-month follow-up to assess changes in knowledge, attitudes, skills, comfort, and advocacy related to sexual and reproductive health care for persons with disabilities. Participants in the intervention group will also complete an immediate post-intervention survey after the three-day curriculum.

This study will evaluate the real-world effectiveness of a four-day Afrocentric sexual and reproductive health curriculum for health professional students in Tanzania. Medical, nursing, and midwifery students from the State University of Zanzibar, Kilimanjaro Christian University, and the University of Dodoma will receive the curriculum. The curriculum covers sexual health across the lifespan, sexual dysfunctions, key populations, sexual violence, clinical skills training, ethics, policy writing, community resources, and cultural considerations. Student outcomes will be assessed using surveys at baseline, immediately after the curriculum, and at 3-month and 12-month follow-up to examine changes in sexual health knowledge, attitudes, and sexual history and counseling skills.

The Effect of Health Belief Model-Based Disaster Education for Parents of Children With Special Needs on General Disaster Preparedness Beliefs and Disaster Preparedness Levels

This study aims to evaluate the effect of a Health Belief Model (HBM)-based disaster education program on general disaster preparedness beliefs and disaster preparedness levels among parents of children with special needs. Children with special healthcare and developmental needs are particularly vulnerable during disasters, and parental readiness plays a critical role in mitigating risks. The study is designed as a quasi-experimental (or randomized controlled) interventional trial with an intervention and a control group to determine whether structured, model-based training improves preparedness behaviors and disaster beliefs among parents.

Effect of Virtual Reality-Based Handwashing Education on Knowledge, Skills, and Emotional Indicators in Preschool Children

A randomized controlled trial designed to evaluate the effects of virtual reality-based handwashing education on handwashing knowledge, skills, and emotional indicators in preschool children aged 5-6 years. The study will be conducted in a kindergarten setting in Istanbul, Turkey, with a total of 66 children who meet the inclusion criteria. Participants will be randomly assigned to one of three groups: a virtual reality-based education group, a traditional handwashing education group, or a control group receiving no intervention. Data will be collected using a sociodemographic information form, a handwashing knowledge form, a handwashing skill assessment form, and the Children's Emotional Indicators Scale. Outcomes will be assessed at baseline and 2 weeks after the intervention.

proState Cancer Health Education to pRomote Early sreENing Uptake (SCREEN): A Pilot Randomised Control Trial

Prostate cancer is an issue of significant public health concern. Yet in low- and middle-income countries like Nigeria, men are adversely affected due to factors including poor early prostate cancer screening uptake. Yet a gap remains in addressing this urgent problem. The proposed study seeks to pilot the feasibility and acceptability of a novel co-produced workshop intervention called "proState Cancer awareness education to pRomote Early screENing uptake (SCREEN) with men who are not or partially up to date with their screening. The SCREEN intervention is designed to raise awareness of prostate cancer, its symptoms, implications for late screening, the benefits of early screening, avenues for screening uptake, and also addressing anxiety related to screening uptake. The SCREEN intervention is low-intensity and lasts approximately two hours. The proposed study also aims to pilot and test the instrument to determine its effectiveness and cost-effectiveness, including the mechanism by which the intervention might work.

Effect of Simulation-Based First Aid and Basic Health Training on Parents of Children With Special Need

Childhood accidents and sudden health emergencies are significant public health concerns that may lead to severe injury or death. Parents, as primary caregivers, play a critical role in providing timely first aid and basic health interventions; however, studies indicate that their knowledge and practical skills are often limited, particularly among families of children with special needs. Therefore, structured training programs are essential. This study aims to evaluate the effect of 5E (Engage, Explore, Explain, Elaborate, and Evaluate)model-based simulation training in first aid and basic health on the knowledge and practical skills of parents of children with special needs. By integrating active learning, hands-on workshops, and interactive teaching methods, the program seeks to enhance theoretical knowledge and practical competence, ultimately supporting safer and more effective responses to pediatric emergencies.

Effectiveness of an Audiovisual Disaster-Education Intervention on Disaster Risk Perception and Preparedness Belief Among Senior High-School Adolescents

This cluster-randomized controlled trial tests whether a short, standardized disaster-education video improves two psychological precursors of disaster preparedness among senior high-school students in a hazard-prone district of West Kalimantan, Indonesia. Twelve intact classes at one senior high school will be randomized 1:1, stratified by grade level, either to view a purpose-built audiovisual disaster-education module (approximately 20 minutes, shown twice in a single classroom session) or to view an attention-matched general adolescent-health video of similar length on an unrelated topic. Randomization is at the class level to reduce contamination between students, and the individual student is the unit of analysis. All students in a participating class view the video allocated to that class; a randomly drawn subsample of twelve students per class, 144 in total, completes the study questionnaires. Two co-primary outcomes are measured in every participant. The first is disaster preparedness belief, measured by the General Disaster Preparedness Belief (GDPB) scale. The second is disaster risk perception, measured by the Disaster Risk Perception Scale (DRPS). Both are collected at baseline before allocation, immediately after the session, and again four weeks later. The intervention and both instruments are grounded in the Health Belief Model, which predicts that raising perceived threat contributes to readiness to act. An exploratory mediation analysis will test whether change in risk perception explains part of any effect on preparedness belief. After the four-week assessment, control classes are offered the full disaster-education intervention.

Digital Storytelling and Breastfeeding Education

The aim of this study was to evaluate the effect of breastfeeding education provided using the digital storytelling method on mothers' breastfeeding self-efficacy and breastfeeding success. The study was conducted using a quasi-experimental pretest-posttest control group design. A total of 216 postpartum women participated in the study, including 108 women in the intervention group and 108 women in the control group. The intervention group received breastfeeding education based on the digital storytelling method, while the control group received routine breastfeeding education provided in the hospital. Breastfeeding self-efficacy and breastfeeding success were evaluated after the intervention.

Effectiveness of Health Education Program on Musculoskeletal Pain Management in Primary School Students

Musculoskeletal pain during childhood can negatively affect school attendance, physical activity, and social participation. This study will evaluate the effectiveness of the school-based health education program 'SocLaLola', which uses a comic-based narrative to introduce children to pain science concepts and promote healthy lifestyle habits. The intervention will be compared with a standard program focused on sedentary behavior prevention. Students aged 8 to 11 years from two primary schools will participate. The primary objective is to determine whether SocLaLola is more effective than the comparison program in improving children's knowledge about pain and in reducing fear-avoidance beliefs related to physical activity.

QR Code Video Education for ICU Family Members

This prospective randomized controlled study aims to evaluate the effect of a QR code-based digital information video on knowledge level and anxiety among family members of intensive care unit (ICU) patients. Participants will be randomly assigned to either a control group receiving routine verbal information or an intervention group receiving routine verbal information plus access to a standardized QR code-based educational video. Knowledge level, anxiety, and satisfaction with information will be assessed at baseline, within 24 hours after the intervention, and 72 hours later. The study will determine whether digital video-based information improves understanding of the ICU environment and reduces anxiety among family members.

Women's Healthy Aging and Menopause; (WHAM)

The present study will examine whether women at high risk for developing hypertension, i.e., post-menopausal status, at least mild psychological distress, and mildly elevated blood pressure, show improvements in these risk factors after a 12-week Transcendental Meditation (TM) intervention compared to Women's Health Education (WHE). Positive findings will provide initial evidence of using nonpharmacological methods, such as TM, to prevent hypertension in postmenopausal women.

Effectiveness of Education on Preventive Measures Against Acute Respiratory Tract Infections in School-Age Children

This study aimed to evaluate the effectiveness of an animation video-supported education program on preventive measures against acute respiratory tract infections among first-grade primary school children.

Evaluation of the Effect of a PRECEDE-PROCEED Model-Based "Laughter Yoga-Supported Education Program" on Peer Bullying

Adolescence is a critical developmental period marked by rapid cognitive, emotional, and social changes that shape personality and psychosocial functioning. During this stage, peer relationships play a central role in adolescents' mental well-being, academic performance, and social adjustment. However, unhealthy peer interactions and exposure to peer bullying significantly increase the risk of adverse physical, psychological, and social outcomes, including anxiety, depression, low self-esteem, academic difficulties, and risky health behaviors, making bullying a major public health concern. Recent evidence indicates a rising prevalence of peer bullying, particularly among middle school students, highlighting the need for effective school-based interventions. Previous programs have demonstrated reductions in bullying behaviors and improvements in school adjustment and self-confidence, yet meta-analytic findings suggest that existing educational interventions have limited effectiveness, underscoring the need for innovative and theory-driven approaches. The PRECEDE-PROCEED Model offers a comprehensive framework for designing sustainable health promotion interventions by addressing predisposing, enabling, and reinforcing factors influencing behavior. In this context, a laughter yoga-supported education program grounded in this model aims to increase adolescents' awareness of peer bullying, enhance physiological, psychological, and social well-being, strengthen social interaction, and improve quality of life. To date, no studies have examined the effects of a PRECEDE-PROCEED Model-based laughter yoga intervention on peer bullying. The aim of this study is to examine the effect of the "Laughter Yoga-Supported Education Program," developed based on the PRECEDE-PROCEED Model, on peer bullying among adolescents. Objectives: To improve adolescents' levels of awareness regarding peer bullying through the PRECEDE-PROCEED Model-based "Laughter Yoga-Supported Education Program," To enhance adolescents' awareness of health behaviors related to peer bullying through the PRECEDE-PROCEED Model-based "Laughter Yoga-Supported Education Program," To develop adolescents' social skills through PRECEDE-PROCEED Model-based laughter yoga educational practices, To significantly reduce the post-test mean peer bullying scores of adolescents in the intervention group compared with their pre-test mean scores, To ensure that the findings of the study contribute to the literature and guide future research on PRECEDE-PROCEED Model-based interventions. Hypotheses: H0-1: There is no significant difference in Peer Bullying Identification Scale scores between adolescents who receive the PRECEDE-PROCEED Model-based Laughter Yoga-Supported Education Program and those who do not. H1-1: There is a significant difference in Peer Bullying Identification Scale scores between adolescents who receive the PRECEDE-PROCEED Model-based Laughter Yoga-Supported Education Program and those who do not.

Laughter Yoga Integrated PRECEDE-PROCEED Health Education Program in Adolescents

Adolescence is a critical developmental period in which lifelong health behaviors are shaped, and behaviors acquired during this stage significantly influence health outcomes in adulthood. Physical activity, healthy nutrition, adequate sleep, stress management, and positive social relationships are among the key determinants of adolescent health. However, current evidence indicates that physical inactivity, unhealthy dietary habits, sedentary lifestyles, and psychosocial problems remain highly prevalent among adolescents globally. In addition, insufficient access to health information and inadequate health information-seeking behaviors among adolescents have been reported to be associated with risky health behaviors. Therefore, the development of healthy lifestyle behaviors in adolescents is considered a public health priority. Schools are recognized as strategic settings for health-promoting interventions targeting adolescents due to their significant social and educational influence on health behaviors. Recent systematic reviews and meta-analyses report that school-based and multi-component interventions have positive effects on adolescents' health behaviors and psychosocial well-being. The integration of behavioral and psychosocial components in school-based health education programs has been associated with more effective and sustainable improvements in adolescent health outcomes . In this process, school health nurses play a critical role in planning and implementing preventive and health-promoting interventions for adolescents . Moreover, it has been reported that healthy behaviors gained through school health nursing interventions may persist into adulthood . Additionally, a systematic review of health education interventions has shown that multi-component approaches-such as classroom education combined with school policies, parental involvement, and school-community collaboration-produce more significant effects on adolescent health outcomes. In recent years, there has been increasing interest in complementary approaches supporting stress management and emotional well-being in school-based interventions. In this context, laughter yoga is described as a low-cost, feasible, and group-based method associated with reduced stress, improved psychological well-being, and enhanced social interaction. Experimental studies conducted with adolescents have also demonstrated that laughter yoga has positive effects on school burnout, hope, and educational stress. However, the literature indicates a limited number of studies examining the integration of laughter yoga into structured school-based health education programs and its effects on healthy lifestyle behaviors. In line with the life-course health perspective, school-based interventions aimed at health promotion during childhood and adolescence are reported to be critical for the sustainability of healthy lifestyle behaviors. In this context, the PRECEDE-PROCEED Model is a theoretical framework widely used in the planning and implementation of health promotion programs, systematically assessing behavioral, environmental, and psychosocial factors influencing health behaviors. Studies based on the PRECEDE-PROCEED Model have demonstrated its effectiveness in improving health behaviors among adolescents. Furthermore, current evidence emphasizes that parental involvement in school-based health interventions strengthens the sustainability of behavior change, highlighting the need for further research in this area. The literature indicates that no studies have examined the effects of a health education program based on the PRECEDE-PROCEED Model integrated with laughter yoga on adolescents' healthy lifestyle behaviors. This gap highlights an important research need for interventions that combine a theoretical behavior change framework with complementary practices that may enhance psychosocial well-being. Study aim Accordingly, the aim of this study is to evaluate the effect of a health education program based on the PRECEDE-PROCEED Model and integrated with laughter yoga on healthy lifestyle behaviors of secondary school students. Study hypotheses H1: Students who receive a health education program based on the PRECEDE-PROCEED Model and integrated with laughter yoga will have significantly higher healthy lifestyle behavior scores compared to the control group.

Evaluation of "C'Est La Vie!" Digital Health Education

The University of California, Los Angeles (UCLA) will lead the online evaluation of four digital health campaigns developed by a non-governmental organization (NGO), Réseau Africain de l'Éducation pour la Santé (RAES), or African Network for Health Education in English, from West Africa and delivered via social media. The full evaluation study will begin enrolling participants in Fall 2023 and will conclude in Winter 2026. Approximately 3,000 participants will be recruited for each of the four campaigns (n=12,000), and each campaign will last approximately 2 months. The four campaigns are scheduled to take place in Fall 2023, Winter 2025, Fall 2025, and Winter 2026, corresponding to evaluation activities including baseline and follow-up data collection. The scope of work for UCLA will center around evaluation activities related to program activities developed and implemented by the non-governmental organization. The digital and online programming will be developed and implemented by the non-governmental organization with the goal of strengthening sexual and reproductive health among young people in Senegal, Burkina Faso, and Cote d'Ivoire. UCLA will lead the evaluation, examining if health education programming contributes to this goal by developing and implementing an evaluation design for digital and online programming.

Educational Models for Tobacco Exposure Awareness

This is a randomized controlled trial comparing the effects of peer education and traditional education on increasing knowledge and awareness of secondhand and thirdhand tobacco smoke exposure among geriatric care program students. Tobacco use and passive smoking are serious public health problems that cause millions of deaths each year and are highly prevalent among university students. Not only smoke dispersed in the air (secondhand smoke), but also toxic residues that accumulate on surfaces and can be absorbed through the skin and ingestion (thirdhand smoke) carry carcinogenic risks. It is a professional obligation for these students, who are the health professionals of the future, to protect the vulnerable elderly population they will serve from this exposure (especially residues carried on clothing/hair). It is also aimed to protect their own health against the risk of smoking triggered by occupational stress. Traditional education that only imparts information may be insufficient in changing behavior. Peer education based on Social Learning Theory offers a sincere and effective alternative that encounters less resistance among young people. While existing experimental studies in the literature generally focus on "active smoking and motivation to quit," this study fills an important gap by focusing on passive and third-hand exposure. If successful, this peer education model could be implemented as a standardized educational module at the national level in university campuses. Research hypotheses: H1: Students who receive peer education have higher levels of knowledge about secondhand smoke than students who receive traditional education. H2: Students who receive peer education have higher levels of awareness about thirdhand smoke than students who receive traditional education. H3: There is a difference between the pre- and post-intervention and between the experimental and control groups in terms of students' average scores for their awareness level of secondhand smoke. H4: There is a difference between the pre- and post-intervention and between the experimental and control groups in terms of students' average scores for their knowledge level of thirdhand smoke.
