Design and Validation of a Self-care Evaluation Instrument to Prevent Diabetic Foot.

PMID 36264694WHAT IT FOUND
A new 26-item questionnaire measures diabetic foot self-care across maintenance, monitoring, and management.
It shows adequate reliability and validity in Colombian adults with type 2 diabetes, but has not yet been tested for detecting changes over time.
Key findings
01The final instrument consists of 26 items distributed into three independent scales: maintenance, monitoring, and management of self-care.
02Internal consistency was acceptable for the maintenance scale (Cronbach's alpha = 0.70) and the management scale (Cronbach's alpha = 0.732).
03The study did not test the instrument's ability to detect changes in self-care behavior over time.

What it does not show
The study did not test if the instrument can detect changes in self-care over time, so it is not yet proven useful for measuring the effect of an intervention. The sample was recruited from four healthcare centers in one municipality in Colombia, so results may not apply to other populations. The fit indices for the monitoring scale were not optimal, particularly for the model in patients without symptoms. Participants were excluded if they had high comorbidity or mental/sensory deficits, so the instrument has not been validated for these more complex patient groups.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not use this instrument to measure the effectiveness of a nursing intervention or education program. The study did not test the instrument's sensitivity to change over time, so it is currently validated only for describing self-care status at a single point in time.
