Introduction:
The aging population presents a growing challenge for global health systems. The Sense of Coherence (SOC) is a psychological resource that enables individuals to perceive life as comprehensible, manageable, and meaningful. Strengthening SOC in older adults is essential to enhance their well-being and reduce the risk of disease. Understanding the personal factors associated with SOC is crucial for developing effective health promotion strategies tailored to this demographic.

Methods:

This quantitative, descriptive, and correlational study was conducted between March and June 2025. A total of 166 older adults participated in the study. All participants were enrolled in the "Más Adultos Mayores Autovalentes" program at primary health care centers in Talcahuano, Chile. Data collection involved a sociodemographic questionnaire, the Sense of Coherence Scale (SOC-13), and the Self-Transcendence Scale (STS), both validated in Spanish-speaking populations.

Expected Results:

The study aims to provide significant evidence on the relationship between personal factors and Sense of Coherence (SOC) among older adults. It is expected that a significant relationship will be found between personal factors (biological, psychological, social, and spiritual) and SOC in this population. The findings are anticipated to inform nursing professionals in designing more effective interventions focused on strengthening SOC, thereby improving quality of life and preventing diseases in older adults.

Conclusions:
Identifying personal factors associated with SOC in older adults will contribute to optimizing health promotion and disease prevention strategies, tailored to the specific needs of the elderly population. This study will offer a solid foundation for the development of public policies and clinical practices aimed at enhancing geriatric care.
