Summary
This study developed a new self-management scale for children with type 1 diabetes mellitus (T1DM). The scale demonstrated strong validity and reliability for use in Turkish culture.
Area of Science:
- Pediatrics
- Endocrinology
- Psychometrics
Background:
- Type 1 diabetes mellitus (T1DM) requires significant self-management skills in children.
- Existing assessment tools may not adequately capture the nuances of pediatric T1DM self-management.
- Developing culturally relevant and psychometrically sound measures is crucial for effective intervention.
Purpose of the Study:
- To develop a Type 1 Diabetes Mellitus Self-Management Scale (T1DM-SMS) tailored for children.
- To rigorously assess the psychometric properties, including validity and reliability, of the newly developed scale.
Main Methods:
- A methodological study involving 212 children (aged 7-12) with T1DM.
- Content validity assessed by pediatric endocrinology and nursing experts.
- Psychometric evaluation included Cronbach's alpha, McDonald's omega, split-half reliability, and factor analyses (exploratory and confirmatory).
Main Results:
- The T1DM-SMS exhibited high internal consistency (Cronbach's alpha = 0.893 overall).
- Exploratory and confirmatory factor analyses supported a robust four-factor structure explaining over 57% of the variance.
- All fit indices in confirmatory factor analysis indicated acceptable model fit.
Conclusions:
- The developed T1DM-SMS is a valid and reliable instrument for assessing self-management in children with T1DM.
- This scale provides a valuable tool for clinicians and researchers working with pediatric T1DM populations in Turkish culture.

01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
01:22Diabetes Mellitus: Overview and Type I Subtype
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...

01:22Diabetes Mellitus: Type 2 and Gestational
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...
01:15Diabetes: Management and Pharmacotherapy
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.

01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
