• Objective: The purpose of this study was to develop a Fluid Management Self-Efficacy Scale for Hemodialysis Patients. Internal consistency, structural validity, and criterion-related validity were tested. Methods: Items were developed to assess self-efficacy in a number of situations associated with difficulty in fluid management. Items were generated from an analysis of interview data in people receiving hemodialysis, and those were analyzed based on the theory of Self-Efficacy of Bandura. A panel of professionals with knowledge of the self-efficacy theory reviewed the first draft of the scale. After face validity, the study was conducted. Data from 220 hemodialysis patients were collected, and 209 subjects were analyzed. Results: A one-factor structure was revealed from the results of exploratory factor analysis. The scale items numbered 15, and the cumulative contribution rate was 55.7%. Structural and criterion-related validities were supported. The Fluid Management Self-Efficacy Scale for Hemodialysis Patients was significantly correlated with the interdialytic weight gain. The high alpha coefficient (0.95) supported the scale as internally reliable. Conclusion: The Fluid Management Self-Efficacy Scale for Hemodialysis Patients was revealed to have satisfactory psychometric properties. The scale may be used in research or in clinical settings to study the mediating effects of self-efficacy or to modify hemodialysis patients' fluid management behavior. Although this first validity study is promising, further validation focusing on reliability and validity is needed.
