This study was designed to identify the relationship of perceived self-efficacy and sick-role behavioral compliance in diabetic children. The forty-two diabetic children participating in this study were selected from outpatients. The period of data collection was August 8 to December 9, 1994. Collected data were analyzed by means of chi-square test, t-test, Pearson correlation using SPSS/PC+. The result are summarized as follows: 1. The mean score of perceived self-efficacy was 3. 21 that of sick-role behavioral compliance 3.17. 2. Perceived self-efficacy and sick-role behavioral compliance had a positive correlation which was statistically significant (r=0.77, P<0.001). 3. There were statistically significant difference in perceived self-efficacy according to age(p<0. 01) and acknowledgment of prescribed calories in the diabetic diet (p<0.001). 4. There were statistically significant difference in sick-role behavioral compliance according to age(p<0.01) and acknowledgment of prescribed calories in the diabetic diet (p<0.001). These results suggest that perceived self-efficacy is an important variable in the compliance of diabetic children. Nursing intervention needs to be directed at promoting perceived self-efficacy to maintain sick ?role behavioral compliance for diabetic children. Therefore programs of nursing intervention should be revised in order to promote perceived self ?efficacy in diabetic children.
