Development of an assessment scale for treatment compliance in type 2 Diabetes Mellitus in Turkish population: Psychometric evaluation.
Ayla Demirtaş, Nalan Akbayrak
PMID 31406748WHAT IT FOUND
A Turkish diabetes treatment-compliance scale grouped 350 adults' answers into seven meaningful barriers and gave stable scores when repeated.
It may help nurses spot non-adherence, but has not been tested to improve care.
Key findings
01The final 30-item scale had a Cronbach's alpha of 0.77.
02In 101 patients, first and second scale scores correlated at r = 0.99 with P < 0.001.
03Scale scores correlated with the Attitudes Toward Diabetes Scale at r = 0.31 with P < 0.001.

What it does not show
The scale relies on self-report, and patients may hide answers they find objectionable or present themselves favourably. It was developed only in Turkish-speaking volunteers with type 2 diabetes attending outpatient clinics in Ankara, so it may not work the same way in other languages, cultures, or settings. The paper reports measurement properties rather than outcomes from using the scale in care. Some items with weak item-total relationships were kept because they increased the overall consistency score. The criterion validity analysis is reported inconsistently, with different sample sizes for the attitude scale.
Declared interests
The authors declared no conflict of interest and reported no specific grant funding.
The easy way to misread this
Do not read this as proof that the scale improves diabetes care or glycaemic control. It was developed and tested as a questionnaire in Turkish adults with type 2 diabetes, and no clinical outcome was reported.
