The effect of seven-step educational strategy on knowledge of diabetic foot ulcer prevention, critical thinking and self-efficacy of nursing students: A randomized controlled trial.

BACKGROUND

Diabetic foot ulcer is a significant complication of diabetes that carries a high mortality risk and is associated with substantial financial costs. Choosing a suitable educational model for nursing students as future nurses is necessary to improve knowledge and manage issues related to caring for diabetic patients.

OBJECTIVES

To determine the effect of education based on the 7E learning cycle model on the knowledge of diabetic foot ulcer prevention, critical thinking, and self-efficacy in nursing students.

DESIGN

A single-blind, randomized controlled trial with a parallel group.

SETTINGS: This study was conducted in a nursing school and hospitals covered by it in Iran.

PARTICIPANTS

98 students studying in the fourth semester of the Bachelor of Nursing course.

METHODS

Students were divided into two distinct groups at random: an experimental group (class A, with 51 participants), and a control group (class B, with 47 participants). The participants of the experimental group were provided with an education based on the 7E learning cycle model, while the control group received conventional teaching method. Data collection methods included pre- and post-tests using research instruments (demographic questionnaire, Kaya Diabetic Foot Prevention Knowledge Questionnaire, Ricketts' Critical Thinking Disposition Questionnaire, and General Self-Efficacy Scale). The data were analyzed using descriptive statistics, non-parametric Mann-Whitney and Wilcoxon tests, parametric independent sample t-tests, ANCOVA, and paired sample t-tests.

RESULTS

The difference in mean scores of diabetic foot ulcer prevention knowledge (Z = -6.232, p < 0.001), critical thinking (t (50) = -4.382, p < 0.001), and self-efficacy (Z = -4.427, p < 0.001) in the experimental group were statistically significant between the time interval before the intervention and one month after its completion.

CONCLUSIONS

Compared to conventional method of teaching, education based on the 7E learning cycle model is a more effective method to improve nursing students' knowledge of diabetic foot ulcer prevention, critical thinking, and self-efficacy.
