BEHAVIORAL SELF-REGULATION IN ADOLESCENTS WITH TYPE-I DIABETES - NEGATIVE AFFECTIVITY AND BLOOD-GLUCOSE SYMPTOM PERCEPTION

The hypothesis that negative affectivity (NA) is associated with accur acy of blood glucose (BG) symptom perceptions and diabetes control was assessed. After completing measures of BG symptom beliefs and NA-rela ted constructs (i.e., attentional focus and trait anxiety), 35 adolesc ents with insulin-dependent diabetes monitored their physical symptoms and their actual BG levels 3 times daily for 2 weeks. Each subject's actual BG symptoms were determined by correlating symptom ratings with BG levels and were then compared with symptom beliefs. Those who were more internally focused were more able to discern which symptoms actu ally covaried with BG fluctuations; those with higher trait anxiety te nded to misattribute non-diabetes-related symptoms to BG levels. Final ly, interactions suggested that those who both attend to internal phys ical sensations and experience-heightened anxiety display poorer metab olic control.
