PMID 28562700WHAT IT FOUND
A Brazilian Portuguese diabetes self-care confidence scale was understood by adults with type 2 diabetes and gave consistent scores.
It helps nurses assess confidence in self-care, not prove that any treatment works.
Key findings
01The adapted scale was tested in 200 adults with type 2 diabetes and produced an average total score of 4.05 on a 1-to-5 scale.
02The full scale gave consistent scores overall (0.78), while the blood-sugar items were least consistent (0.57) and the physical-exercise items most consistent (0.86).
03The original four domains remained, but some items were suggested for change and the authors kept them to preserve self-monitoring and self-regulation content.

What it does not show
The validation used a non-probabilistic sample from one university outpatient unit, so results may not apply to other Brazilian regions or clinical groups. Participants were adults with type 2 diabetes without advanced chronic complications, so it says little about more complicated diabetes care. The first factor analysis suggested item changes, and the authors kept the original domains, so the scale structure may not be settled. The study did not compare the scale with another validated diabetes self-efficacy instrument because none was available for this population. One item about checking blood sugar was not part of many patients' routines because they did not have a glucose meter, which may affect how that item is understood.

The easy way to misread this
Do not read this as evidence that the scale improves diabetes self-care or control. It is a measurement instrument validated in a limited sample, and the paper reports no intervention outcome.
