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

Abstract

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.

OBJETIVO

Determinar las propiedades psicométricas del CoNOCidiet-Diabetes, un nuevo instrumento basado en el resultado enfermero “Conocimiento: dieta prescrita”.

MÉTODOS

Diseño metodológico. Los participantes fueron 359 pacientes diagnosticados de diabetes que acudieron a 27 centros de atención primaria de salud en España. Se comprobó la fiabilidad (consistencia interna y test-retest), la validez (validez de criterio convergente, validez de contenido concurrente y validez de grupos conocidos) y la sensibilidad al cambio.

RESULTADOS

El CoNOCidiet-Diabetes ha mostrado evidencias de tener unas propiedades psicométricas aceptables como instrumento, pero algunos ítems deben ser revisados.

CONCLUSIONES

Esta investigación proporciona un nuevo instrumento desarrollado para medir específicamente el conocimiento sobre dieta en personas con diabetes.

IMPLICACIONES PARA LA PRÉCTICA ENFERMERA

La literalidad del CoNOCidiet-Diabetes con el resultado enfermero “Conocimiento: dieta prescrita” facilita la medición de este último utilizando las declaraciones del paciente.
