Summary
A new scale, the Diabetes Awareness and Insight Scale (DAS), was developed to measure illness awareness in type 2 diabetes (T2DM). This tool helps understand how awareness impacts T2DM management and clinical outcomes.
Area of Science:
- Endocrinology
- Psychology
- Health Services Research
Background:
- Type 2 diabetes mellitus (T2DM) affects 8.5% of the global population.
- Impaired awareness or denial of T2DM is common and impacts clinical outcomes.
- Existing research on T2DM illness awareness is limited.
Purpose of the Study:
- Develop and validate the Diabetes Awareness and Insight Scale (DAS).
- Measure illness awareness in individuals with T2DM.
- Provide a tool for epidemiological studies on T2DM management.
Main Methods:
- Developed a 9-item self-report scale (DAS) assessing four domains of illness awareness.
- Recruited 100 participants with T2DM via a digital platform.
- Administered the DAS to assess validity, reliability, and factor structure.
Main Results:
- The DAS demonstrated good convergent/discriminant validity and internal consistency.
- One-month test-retest reliability was confirmed.
- Exploratory factor analysis revealed a three-factor structure for the DAS.
Conclusions:
- The DAS is a novel, easy-to-administer scale for measuring subjective illness awareness in T2DM.
- It is the first scale of its kind, offering potential for epidemiological research.
- The DAS can examine the role of awareness/denial in T2DM clinical outcomes and management.

4.2K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

01:15Hypoglycemia and Glucagon
727
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
