Background: Colorectal cancer is common, the presenting symptoms are non-specific, and the stage of disease at diagnosis is closely related to survival. Regular screening reduces morbidity and mortality from this disease. The Health Belief Model posits that individuals are more likely to engage in preventive health behavior. Aim: to evaluate the effectiveness of nurse-led intervention on adults' health beliefs and screening behaviors toward colorectal cancer. Design: A quasi experimental design. Setting: This study was conducted in outpatients' clinics at Menoufia University hospital, Egypt. Sample: A purposive sample of 140 participants who were attended at pre-mentioned settings. Instruments: as following: I. Structured interviewing questionnaire, II: colorectal cancer awareness questionnaire. III: colorectal cancer Self-reported screening behavior questionnaire, IV: colorectal cancer Knowledge questionnaire. V: Health beliefs model questionnaire. Results: the mean age of the studied sample was 54.27± 7.271 and 52.129±6.324 for study and control groups respectively. Regarding to risk factors assessment 55.7% of study group and 65.7% of the control group has Low-fiber, protein-rich, and high fats in their diet. 80.0% of the study group and 84.3% of control group had negative family history for CRC. There was statistical improvement of total awareness score among study group (9.39±4.31) than those in control group (5.02±2.93) at post-intervention. The mean total behavior scores were 7.93±2.11 and 5.28±3.28 for study and control group respectively at post-intervention. There were statistical significance differences in total mean score of health belief model variables among study group at post intervention in which p value = .000. Conclusion: Nurse led intervention had positive impact on adult health beliefs, screening behaviors also improving their knowledge and awareness regarding colorectal cancer. Recommendations: Designing effective nursing strategies to address barriers of CRC screening and improve CRC knowledge and awareness, which is critical to achieving greater screening compliance.

Objective: the study was carried out to assess effectiveness of nursing intervention regarding self insulin administration among diabetic patients. Methods: Research design: A quazi experimental design was utilized. Setting: Medical Clinic at Health Insurance Hospital, at Shebein El-Kom, Menofia Governorate, Egypt. Subjects: Convenient sample of 200 diabetic patients who were self insulin administered. Tools for data collection: Interviewing questionnaire includes socio demographic date, knowledge questionnaire sheet regarding self-administration of insulin, and observational checklist. Results: Majority of studied sample was married female that have negative family history of diabetes, and are insulin injected for more than 1 year. Majority of studied sample have poor knowledge and incorrect practice their barriers to continuing insulin were pain, too expensive, and weight gain, the main points that improved by nursing intervention were as follows: air bubbles removing before injecting using the insulin syringe, frequently change site of injections, before injection keep insulin vial at room temperature at least for 15 minutes, and disposal of used needles in a safety box at home, the only statistical difference between knowledge and practice was after one week of intervention among study group. Conclusions: The study concluded that the knowledge regarding insulin injection and self-administration of insulin practice after the nursing intervention were increased which is related to the effectiveness of the nursing intervention.
