Background/Objectives: Bullying refers to a specific form of mistreatment that occurs in the school setting and is characterized by intentionality and persistence over time. It should be noted that some elements, such as low self-esteem and lack of social skills, are usually present in both victims and aggressors, so interfering in these aspects can lead to a decrease in the incidence. Thereby, being a victim of bullying is a key factor in the development of multiple mental health issues, such as depression or even suicide. Consequently, mental health nurses play a fundamental role in health education in order to be able to act when necessary and to prevent these types of unfavorable circumstances that can lead to psychiatric disorders. This systematic review aimed primarily to evaluate the effectiveness of psychoeducational programs in reducing school bullying and, secondarily, to analyze their influence on children’s self-esteem. Methods: Data were obtained through a comprehensive search of PubMed, Cochrane, and Scielo, following PRISMA guidelines. Studies evaluating evidence-based interventions, including the Olweus Bullying Prevention Program (OBPP), the KiVa Anti-Bullying Program (KiVa), Positive Behavioral Support systems, and standardized social–emotional learning programs, were eligible for inclusion. Results: Findings revealed that most interventions showed a positive impact on bullying reduction and self-esteem improvement. However, effectiveness differed depending on contextual factors, such as the educational stage, school climate, cultural setting, and the degree of family involvement, as well as the extent to which each program was adapted to the specific needs of each school environment. Conclusions: Psychoeducational programs demonstrate overall effectiveness in reducing bullying behaviors and enhancing self-esteem in children. Nevertheless, outcomes differ depending on school characteristics, cultural context, and the level of family participation, highlighting the need for interventions tailored to each educational setting.

Objective: To describe the characteristics and outcomes of using the Oldfry technology application in older adults, analyzing changes in frailty and fall risk after its implementation. Design and Methods: Observational, analytical, prospective, cross-sectional, and multicenter study conducted in residential centers in Plana Baja (Castellón, Spain). A total of 156 older adults over 65 years old participated, selected based on specific criteria and voluntary consent. Sociodemographic, anthropometric, and clinical variables were collected, including fall history, sensory problems, medication use, and standardized cognitive, nutritional, and functional assessment scales. The study was approved by the Ethics Committee of Universitat Jaume I. Results: The sample included 156 individuals (median age: 84 years). Women showed greater functional dependence (Barthel scale) and cognitive impairment (Pfeiffer scale). The Oldfry device detected frailty with statistically significant differences. A direct relationship was found between greater functional dependence and higher fall risk, as well as between higher comorbidity and increased fall risk. An adequate nutritional status was associated with a lower fall risk. Conclusion: The use of Oldfry is crucial for assessing frailty and fall risk in older adults. Factors such as functionality, comorbidities, and nutritional status directly influence fall prevention, highlighting the importance of technological tools in monitoring these risks.

Objective: To validate the Oldfry instrumental device for efficiently detecting the risk of falls and frailty in older adults. Design and Methods: An observational, analytical, cross-sectional, multicenter, non-randomized study to validate an instrumental device. It was conducted in several nursing homes for the elderly in the province of Castellón, Comunidad Valenciana, Spain, from February to April 2024. The estimated necessary sample size was 149 people. Specific selection criteria and voluntary acceptance to participate in the study were established. Sociodemographic, anthropometric, and other variables such as fall history in the past year were collected. A descriptive and comparative analysis of the variables was performed. The validity and reliability of the device in its measurements were determined to compare the results of the Timed Up and Go (TUG) test and the Short Physical Performance Battery test (SPPB), with respect to the Oldfry instrumental device. Informed consent was obtained from all participants, and the study was approved by the Bioethics Committee of the University Jaume I. Results: The sample consisted of 151 participants with a median age of 84 years (IQR [78.0–91.0]), comprising 39.10% men and 60.90% women, 65 years of age or older. Oldfry presents a sensitivity of 45.90% and a specificity of 72.7% for the risk of falls with a correlation R: 0.773 and an ICC concordance: 0.821. For frailty assessment, it shows a sensitivity of 91.90% and a specificity of 9.10% with an R: 0.854 and ICC: 0.805. Conclusions: This device has proven to be an effective tool for detecting both the risk of falls and frailty in older adults residing in institutions, showing high levels of reliability, sensitivity, and high concordance and correlation in both measurements. Future studies are anticipated to evaluate the benefits of this application.
