Reducing Loneliness and Social Isolation Through the HELPeN Telephone-Call Program: Results from a Randomized Controlled Trial in Older Adults Living in the Community
Background/Objectives: Loneliness is a significant public health issue among older adults, especially in rural and socioeconomically vulnerable groups. Telephone-based interventions have become a scalable, cost-effective way to reduce social isolation, although evidence of their long-term effects on various health outcomes remains limited. This study aimed to assess how effective HELPeN, a structured telephone program delivered by trained nursing students, is in decreasing loneliness and enhancing psychosocial and cognitive health in community-living older adults. Methods: A randomized controlled trial was conducted with 119 older adults (≥65 years) residing in the community. Participants were allocated to either an intervention group (n = 65), which received weekly structured telephone calls over 9 months, or a control group (n = 54), which received standard care. Outcomes were evaluated at baseline (M0), mid-intervention (M1–M3), and 3 months after the intervention (M4). The primary outcomes measured included loneliness and perceived social support. Secondary outcomes comprised functional status, comorbidities, depressive symptoms, quality of life, sleep quality, and cognitive function. The data were analyzed using repeated-measures ANOVA with Greenhouse–Geisser correction. Results: Significant group interactions over time were identified for loneliness (F = 5.92, p = 0.001, η2 = 0.067), social support (F = 3.39, p = 0.023, η2 = 0.043), depressive symptoms (F = 3.87, p = 0.019, η2 = 0.046), and cognitive status (F = 5.35, p = 0.002, η2 = 0.063). No significant differences were found for functional status, comorbidity, sleep quality, or quality of life. Conclusions: The HELPeN program demonstrated significant effectiveness in reducing loneliness and social isolation, and in improving emotional, cognitive, and sleep-related outcomes in older adults. As a low-cost and scalable model, this intervention strengthens the role of nursing students in addressing social determinants of health and may be integrated into community and public health strategies targeting vulnerable aging populations.

Prevalence of Unwanted Loneliness and Associated Factors in People over 65 Years of Age in a Health Area of the Region of Murcia, Spain: HELPeN Project
Background/Objectives: Population aging poses many challenges to public health, highlighting loneliness and social isolation as severe problems that affect the physical and mental health of older adults. During the COVID-19 pandemic, these became aggravated. The objective of the present study was to assess the prevalence of loneliness and its relationship with social isolation, depression, cognitive deterioration, sleep quality, and the level of physical mobility and functioning of older adults in Health Area 3 of the Region of Murcia. Methods: A descriptive, observational, and cross-sectional study was performed. The inclusion criteria were age ≥ 65, living in Health Area 3 of the Region of Murcia, and not being institutionalized. The following variables were evaluated: sociodemographic variables, loneliness (UCLA scale), social isolation (DUFSS), depression (GDS), cognitive deterioration (Pfeiffer), sleep quality (PSQI), and mobility (Barthel index). A univariate and multivariate regression model was created to examine how the dependent variable was related to the independent variables. Results: A total of 102 older adults participated in the study. Of these, 31.4% perceived unwanted loneliness and 14.7% low social support. The multivariate regression analysis showed that social isolation, geriatric depression, and cognitive deterioration were significant predictors of loneliness. Conclusions: The findings highlight the importance of developing multifaceted interventions that address not only social isolation but also other interrelated factors such as depression, cognitive deterioration, and sleep quality. The strategies should be centered on community programs and support networks. It is fundamental to perform longitudinal studies to better understand the causal relationships between these variables.

Effects of a Clinical Simulation-Based Training Program for Nursing Students to Address Social Isolation and Loneliness in the Elderly: A Quasi-Experimental Study
Introduction: The population of older adults is rapidly increasing worldwide, presenting both prospects and complexities for society and healthcare professionals to maximize the functional capacity of this age group. Social isolation and loneliness significantly affect this population. The objective was to determine the effectiveness, satisfaction, and perceptions of the simulation-based education practices of a training program for nursing students, which was created to palliate the social isolation and loneliness of older adults. Method: A quasi-experimental study was conducted with nursing students who participated in an online training program using teleservice based on high-fidelity clinical simulation. The program included asynchronous theoretical training and synchronous practical training using an online platform. Five scenarios were designed using simulated phone calls to address the social isolation and loneliness of older adults. Results: Twenty-five nursing students participated in the program, and they had a mean age of 27.44, with 76% of them being women. After the training program, the participants showed statistically significant improvements (p < 0.05) with respect to their knowledge and attitudes towards older adults, and the program was adapted to the best educational practices in simulations. Conclusions: Simulation-based online training efficiently improved the knowledge and attitudes of nursing students towards older adults, improving their ability to address social isolation and loneliness. The high satisfaction and adhesion to the best educational practices underline the usefulness of high-fidelity online simulations, especially in situations in which face-to-face training is not feasible, and accessibility and equilibrium could be guaranteed between work and personal life.
