A New Instrument For Measuring Dietary Knowledge In Patients With Diabetes: Psychometric Testing Of The Conocidiet-Diabetes

PURPOSE To determine the psychometric properties of the CoNOCidiet-Diabetes, a new instrument based on nursing outcome "Knowledge: prescribed diet."METHODS 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.FINDINGS CoNOCidiet-Diabetes has shown evidence of acceptable psychometric properties as instrument but some items should be revised.CONCLUSIONS This research provides a new instrument developed to specifically measure dietary knowledge in individuals with diabetes.IMPLICATIONS For nursing practice: The literalness of the CoNOCidiet-Diabetes with the nursing outcome "Knowledge: prescribed diet" facilitate its measurement using the patient's statements.
