Structural model of self-care agency in patients with diabetes: A path analysis of the Instrument of Diabetes Self-Care Agency and body self-awareness.

Aim: The aim of this study was to examine a causal model of self-care agency by exploring the relationship between the structure of "body self-awareness" and the structure of the Instrument of Diabetes Self-Care Agency (IDSCA).

Methods: The participants were 353 patients with diabetes. The internal consistency of the six items for body self-awareness was examined by calculating the factor structure using principal factor analysis and Cronbach's alpha.

Reliability and Validity of a Shortened Version of an Instrument for Diabetes Self-Care Agency.

Purpose: The purpose of this study was to develop a shortened version of the Instrument of Diabetes Self-Care Agency (IDSCA).

Methods: In the development of the shortened version of IDSCA, intraclass correlation coefficient 2 (ICC2) analysis was done to determine items to be deleted. However, the 7 subscales were retained.
