Older adults experience physical, emotional, and social changes that may influence their overall quality of life, and spirituality is often considered a vital coping resource in later life. This study determined the relationship between spirituality and quality of life among geriatric patients in a selected Barangay in Sta. Barbara, Iloilo. A quantitative, non-experimental descriptive-correlational and cross-sectional design was utilized. Complete enumeration was employed, involving 63 geriatric respondents aged 60 years and above. Data were gathered using adopted questionnaires measuring spirituality and quality of life. Descriptive and inferential statistics were used to analyze the data at a 0.05 level of significance. Ethical clearance was secured prior to data collection to ensure voluntary participation and confidentiality. Findings revealed that respondents demonstrated a very high level of spirituality and a generally high level of quality of life despite financial limitations. The respondents demonstrated a generally high level of spirituality (overall mean ≈ 4.5–4.9 on a 5-point scale), with the item “to receive more support from your family” obtaining the highest mean score (M = 4.92), while relatively lower scores were observed in items related to the need for a religious leader’s visitation (M ≈ 3.7–3.9). In terms of quality of life, the respondents reported high levels of satisfaction (mean ≈ 4.3–4.6) in areas such as home environment, access to local facilities, and receiving love and affection from others, although moderate scores (mean ≈ 3.6–3.9) were noted in financial and health-related concerns. A significant relationship was found between spirituality and quality of life, indicating that higher spirituality was associated with better perceived well-being. Comparative analysis revealed no significant differences in spirituality when respondents were grouped according to sex, monthly income, and living arrangement (p > 0.05); for instance, respondents living alone (M = 4.61) and those living with family (M = 4.58) showed nearly similar spirituality levels with no significant difference (t = 0.494, p = 0.623). Similarly, quality of life did not significantly differ across demographic groups (p > 0.05). However, correlation analysis indicated a statistically significant but weak positive relationship between spirituality and quality of life among the respondents (n = 63, p < 0.05), suggesting that higher spirituality is associated with better perceived quality of life among geriatric individuals. The study concludes that spirituality plays an important role in enhancing the holistic well-being of older adults. These findings highlight the need to integrate spiritual assessment and support into geriatric nursing care and community health programs to promote improved quality of life among elderly populations.
