Validation of Basic Psychological Needs Scale in terms of Autonomy and Competence

초록

Background: Basic psychological needs affect intrinsic motivation. However, the relationship between selfcare behaviors and the basic psychological needs of patients undergoing renal dialysis has not been proven. We investigated the validity and reliability of the Basic Psychological Needs scale for patients undergoing renal dialysis. Methods: At hospitals in Busan Metropolitan City, 120 patients with chronic renal failure receiving dialysis treatment were examined. The data were analyzed using SPSS 21.0 and AMOS 21.0 and criteria for positively affecting selfcare behaviors in these patients identified. The Basic Psychological Needs scale consists of two subfactors: autonomy and competence. Results: The reliability of the 12 items of the scale based on Cronbach’s α was 0.90; first factor autonomy was 0.90; second factor competence was 0.72; and there was homogeneity between the items. Conclusion: Construct-, convergent-, discriminant-, criterion-related validity and internal consistency were verified. The scale was confirmed as a tool for measuring the basic psychological needs of patients undergoing renal dialysis. © 2023 Kim et al. Published by Tehran University of Medical Sciences.
