Notes: Item 29 asking “If you notice that your blood sugar is too high or low, do you adjust your insulin doses according to what your doctor has prescribed?” was excluded by this analysis to maintain an adequate sample size because only patients taking insulin answer the question. However, it was included in the scoring of the scale when applicable to estimate internal consistency and construct validity. Thus, we recommend including this item when scoring Factor 2 labeled as “Consultative self-care management behaviors” and especially when scoring the whole Self-care management scale in people taking insulin.
