Abstract
OBJECTIVE: To correlate spirituality with the health-related quality of life (HRQoL) in patients with lung cancer. METHODS: A quantitative study was conducted with 74 patients at an oncology hospital in João Pessoa, Paraíba, from July to December 2023. Interviews were conducted using the World Health Organization Quality of Life Spirituality - Religiosity - Personal Beliefs (WHOQOL-SRPB) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Data were processed and analyzed using descriptive and inferential statistics. RESULTS: A weak positive correlation was observed between the connection score and financial difficulties (p = 0.012), as well as a weak to moderate negative correlation between hope and the cognitive score (p = 0.001) on the spirituality and HRQoL scales. CONCLUSION: Aspects of spirituality contribute to the improvement of HRQoL in patients, providing a basis for the development of individualized care plans.
