A New Instrument for Measuring Dietary Knowledge in Patients With Diabetes: Psychometric Testing of the CoNOCidiet-Diabetes.

Abstract

To determine the psychometric properties of the CoNOCidiet-Diabetes, a new instrument based on nursing outcome "Knowledge: prescribed diet." Methodological design. The participant were 359 patients diagnosed with diabetes visiting 27 primary healthcare centers in Spain. Reliability (internal consistency and test-retest), validity (convergent criterion validity, concurrent content validity and known-groups validity), and sensitivity to change was tested. CoNOCidiet-Diabetes has shown evidence of acceptable psychometric properties as instrument but some items should be revised. This research provides a new instrument developed to specifically measure dietary knowledge in individuals with diabetes. For nursing practice: The literalness of the CoNOCidiet-Diabetes with the nursing outcome "Knowledge: prescribed diet" facilitate its measurement using the patient's statements.
