Validation of the self-confidence scale of nursing care in urinary retention.

Objective: to validate an instrument to measure self-confidence of nursing care in urinary retention.
Methods: methodological research study, carried out after ethical approval. A Likert-like scale of 32 items related to nursing care in urinary retention was applied to students of the graduate nursing course. For instrument validation, analysis of the sample adequacy and main components, Varimax orthogonal rotation and internal consistency analyses were developed.
Results: in a sample of 305 students, there was high correlation of all items with the total scale and Cronbach's alpha of 0.949. The scale items were divided into five factors with internal consistency: Factor 1 (0.890), Factor 2 (0.874), Factor 3 (0.868), Factor 4 (0.814) and Factor 5 (0.773), respectively.
Conclusion: the scale meets the validity requirements, demonstrating potential for use in evaluation and research.
