Abstract
in English, Spanish

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.
