Summary
A new 19-item scale, the Type 1 Diabetes Stigma Assessment Scale (DSAS-1), effectively measures perceived and experienced stigma in adults with Type 1 diabetes. This validated tool aids research into diabetes stigma
Area of Science:
- Psychometrics
- Endocrinology
- Social Science
Background:
- Stigma significantly impacts individuals with Type 1 diabetes.
- Existing measures may not fully capture the nuances of diabetes-related stigma.
Purpose of the Study:
- To develop and validate the Type 1 Diabetes Stigma Assessment Scale (DSAS-1).
- To create a reliable self-report measure for assessing diabetes stigma in adults.
Main Methods:
- Qualitative interviews informed item generation.
- Psychometric validation involved factor analysis and reliability testing in a large adult sample (N=898).
Main Results:
- The 19-item DSAS-1 demonstrated strong internal consistency (α=0.93).
- Factor analysis supported a three-factor structure: Treated Differently, Blame and Judgement, and Identity Concerns.
- The scale showed satisfactory validity.
Conclusions:
- The DSAS-1 is a valid and reliable instrument for measuring Type 1 diabetes stigma.
- This brief scale offers a valuable tool for future research on stigma's impact on diabetes self-care and outcomes.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

5.2K
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...

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.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.

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...

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
