Objective:

The main objective of this study was to test an educational intervention that is founded on the theory of self-care and can be applied for teaching purposes in dialogic learning on foot self-care.

Materials and methods:

This is a quantitative study with a quasiexperimental design featuring a pre-test and post-test. There were 40 people in the experimental group and 32 in the comparison group. The "foot self-care" variable was measured through two instruments: "Self-care to prevent a diabetic foot" and "Self-care of the diabetic foot". The latter was developed by researchers from the University of Málaga.

Results:

In the pretest, 35% of those in the experimental group had a low level of self-care; 28%, a medium level; and 37%, a high level. A statistically significant increase (p = 0.000) in self-care was observed after the intervention. On the other hand, the comparison group maintained almost the same percentages, with no significant differences being found.

Conclusions:

The results suggest an educational intervention with a theoretical basis helps to improve foot self-care among people living with diabetes, and nursing plays a fundamental role in its development.
