Children and adolescents account for half of all cases of type 1 diabetes, which is one of the most common pediatric chronic diseases. The disease's effects and the treatment/disease-management protocols patients must follow can lead to a marked deterioration in quality of life, especially for adolescents. Patients' illness perceptions have been shown to impact their quality of life, but do other people's illness perceptions also have an effect? The present study addressed this question by investigating possible links between the quality of life of adolescent patients with type 1 diabetes and illness perceptions, measured in terms of the adolescents' self-perceptions, parents' self-perceptions, and the adolescents' evaluations of their parents' perceptions. We asked 41 adolescents (M = 13.9 years; SD = 1.9) who had been undergoing treatment for type 1 diabetes for at least a year (M = 6.6 years; SD = 3.7) to complete the Diabetes Quality of Life for Youth Questionnaire-Short Form (DQOLY-SF) and the Illness Perception Questionnaire-Revised (IPQ-R). They completed the IPQ-R twice, once to state their own opinions (self-report) and once to give their evaluations of their parents' perceptions. At the same time, but in a different room, their parents (N = 47) completed the IPQ-R (self-report). Quality of life was predicted by gender (p < .05) and by the parents' emotional representations (p < .01) and perceptions of consequences (p < .01) as evaluated by the adolescents. This new approach provides new insights into the impact of parents' perceptions on the quality of life of adolescents with type 1 diabetes.
