Objectives: The principal aim of this study was to identify whether the Newcastle Satisfaction with Nursing Scales (NSNS) could be used on cancer patients. Methods: This was a descriptive, cross-sectional study carried out on cancer patients (n = 298). Results: We found that a majority of cancer patients were around 50 years old (hospitalized patients HP: 49.5 ± 14.9; chemotherapy outpatients COP: 49.4 ± 12.7), were female (HP: 74%; COP: 63.5%), and had received education at least up to elementary level (HP: 70%; COP: 80%). Breast cancer was the principal type of cancer (>34%) in both groups (HP and COP). The groups were comparable in age, sex distribution, place of origin, educational qualification, and type of cancer. Among HP, the experience and satisfaction scales of the NSNS showed good internal consistency (n = 235, α >0.9, r > 0.7), while among COP, only the satisfaction scale showed good internal consistency (n = 62, α = 1.00). Most patients’ perceptions (level of satisfaction) of hospitalization and chemotherapy services were positive (98% and 97%, respectively). Conclusion: An NSNS instrument specifically designed for ambulatory care cancer patients is necessary for it to be useful in assessing cancer patients' perception of nursing care. This will help improve the quality of care in Mexico. The presence of cancer by itself could modify the patients’ satisfaction level. Further large-scale studies are required to inves- tigate the patients’ perceptions of nursing care using the NSNS on different cancer patient groups.
