Abstract

The present study explores accuracy in estimating blood glucose levels (BGL) in children with type 1 diabetes and analyzes the kinds of symptoms and cues which they use to estimate their BGL. Forty two children with type 1 diabetes completed a SI/IC-3 scale consisting of 28 items (22 symptoms and 6 feelings), indicating those which they perceived at the time and their intensity. They estimated their BGL and gave reasons for their estimation, before having a blood glucose level analysis performed. The results indicated great variability in the accuracy of estimating BGL. They showed failures in the correct discrimination of symptoms of hypoglycemia as well as the presence of false beliefs regarding indicative symptoms of hyperglycemia, and the absence of symptoms as an indicator for euglycemia, beliefs which provoke different and frequent errors in the estimation of BGL. Correct use of external signs is shown to be related to correct estimations of normal BGL, as well as hypoglycemia and hyperglycemia. We discuss the implications these results could have on designing psychological intervention procedures for diabetics in the form of training programs to discriminate BGL accurately, taking into account these findings and previous studies completed in the same field.

El presente estudio explora la precisión en la estimación de los niveles de glucosa en sangre (NGS) en niños con diabetes tipo I y analiza el tipo de síntomas o señales en las que se basan para estimar sus NGS. 42 niños con diabetes tipo I completaron una Escala SI/IC-3 compuestas por 28 ítems (22 síntomas y 6 estados de ánimo), señalando las que percibían en ese momento y la intensidad, y estimaron el NGS indicando las razones de su estimación, antes de realizar su análisis de glucosa en sangre. Los resultados indican una gran variabilidad en la precisión en la estimación del NGS, y muestran fallos en la correcta discriminación de los síntomas señales de hipoglucemias, y la presencia de falsas creencias sobre síntomas indicativos de hiperglucemias y sobre la ausencia de síntomas como indicador de normoglucemia, creencias que provocan diferentes y frecuentes errores en la estimación de los NGS. El uso adecuado de las señales externas se muestra relacionado con la estimación correcta de los NGS tanto normales como hipoglucémicos e hiperglucémicos. Se discuten las implicaciones que estos resultados pueden tener para el diseño de procedimientos de intervención psicológica en diabetes en forma de programas de entrenamiento en discriminación de NGS que tengan en cuenta estos hallazgos y los de estudios previos en la misma línea.
