Healthcare service quality is an important aspect of healthcare systems worldwide, as it directly affects patient outcomes and satisfaction (Prakoeswa et al., 2022; Ghildiyal et al., 2022; Pratama & Hartini, 2020). The World Health Organization (WHO) defines health service quality as "the degree to which health care services for a population increase the likelihood of desirable health outcomes" (Manyazewal, 2017). While most studies of service quality focus on patients' perspectives, nurses play an important role in shaping patients' perceptions and experiences (Fabrellas et al., 2020; Athanasakis, 2020; Habahbeh & Alkhalaileh, 2020). Their professional competence is critical to achieving the mission of the health system, and their performance plays an important role in achieving organizational goals (Halabi et al., 2021). The quality of nursing care is associated with patient satisfaction, shorter hospitalization times, and lower healthcare costs (Molina-Mula & Gallo-Estrada, 2020; Apriana & Ratnasari, 2021; Mynaříková et al., 2020). Many studies have explored factors that contribute to high-quality nursing care. Li et al. (2022) found that spiritual care competence is positively associated with the perceived professional usefulness of nurses. Haldane et al. (2022) highlight the challenges nurses faced during the COVID-19 pandemic, emphasizing the need for adequate support and resources to maintain high-quality care. Yanti and Suarningsih (2022) explored the role of spiritual care training in enhancing nurses' ability to meet the spiritual needs of patients during care. However, a few studies have examined nurses' perceptions of service quality (Dureab et al., 2020; Sheikh, 2022). Nursing staff's perceptions of service quality can significantly affect patient care (Mert et al., 2020). A study by Alsufyani et al. (2020) examined nurses' perceptions of health service quality in Saudi Arabia and found that nurses perceived the quality of care to be moderate, with room for improvement on all dimensions of the SERVPERF scale. Similarly, a study by Al-Kandari and Ogundeyin (1998) in Kuwait reported that nurses perceived the quality of care to be satisfactory. Several studies have examined different approaches to measuring service quality and identifying factors that influence nursing staff perceptions (Koyet al., 2020; Tran & Le, 2020; Khodayari-Zarnaq et al., 2021). Previous studies have used the SERVPERF scale to assess the quality of health services in different countries and contexts, providing valuable insights into the factors that contribute to high-quality care (Endeshaw, 2020; Shafei, 2019). The SERVPERF scale is a widely used tool for measuring service quality and assesses five dimensions: concreteness, reliability, responsiveness, assurance, and empathy. It has been adapted for use in healthcare settings (Akdere & Tekingündüz, 2020). Previous studies have demonstrated the validity and reliability of the SERVPERF scale in assessing the quality of nursing services (Akdere et al., 2020). Shafei et al. (2019) reported that the scale was useful in identifying areas for improvement in nursing care, while Labrague et al. (2022) reported a positive relationship between SERVPERF dimensions and nurses' performance. In countries facing conflict and fragile healthcare systems, measuring the quality of health services becomes even more important to identify areas for improvement and ensure the delivery of safe and effective care (Dureab et al., 2020; Qirbi & Ismail, 2017). The healthcare system in Yemen has been severely affected by ongoing conflict, which has led to a decline in healthcare delivery and access to services (Dureab et al., 2020; Qirbi & Ismail, 2017). In addition to the many challenges that health care providers face in providing quality care (Dureab et al., 2020), understanding and improving health service quality is therefore crucial to ensuring that the limited resources available are used effectively and efficiently (Li et al., 2022). Given the limited research on nurses' perceptions of the quality of health services in Yemen, this study aims to fill this gap by using the SERVPERF scale to assess the quality of health services in the country. The findings of this study will contribute to the literature on the quality of health services in conflict-affected countries and provide valuable insights for policymakers and health care providers in Yemen to improve the quality of health services.
