Psychological impact of islet cell antibody screening

The purpose of this study was to evaluate the psychological impact of autoantibody screening and its results on at-risk individuals and family members. Individuals who were antibody positive (AP) were identified through a large-scale screening program conducted at our institute. The sample consisted of nine families in whom 10 AP youngsters (7 M, 3 F) were identified, ranging in age from 6-18 years (mean 11.8, median 10 yr). Seventeen parents and eight diabetic youngsters (mean age 15.2, median 16 yr) participated in the study. Reaction to autoantibody positivity was assessed with the Impact of Event scale (IES). The IES was answered twice: within a week from the disclosure of the AP status, and 3 months later. Parents scored higher than their diabetic children and AP children on both measures of the IES, Intrusion and Avoidance. Three months later both scores were significantly reduced in both the parents and the AP children; however, parents still scored significantly higher on both scores than the AP children. The results suggest that learning one's AP status induces significant anxiety, especially in parents of AP youngsters. Although this initial anxiety dissipates over time it still remains quite high after 3 months. The results highlight the importance of psychosocial counseling for all members of diabetes mellitus screening and prevention trials.
