Insights
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.
Objective:
The aim of this study was to develop a type 1 diabetes mellitus self-management scale for children and to assess its psychometric properties.
Methods:
A methodological, descriptive, correlational, and cross-sectional study was conducted. The research sample comprised 212 children with diabetes aged 7-12 years. Content validity was evaluated by seven experts in pediatric endocrinology, pediatric nursing, public health nursing, and Turkish language. Descriptive statistics, correlation analyses, Cronbach's alpha, McDonald's omega, split-half reliability, and factor analyses were used.
Results:
The Cronbach's alpha for the overall scale was 0.893, and for the subscales, it ranged from 0.757 to 0.845. The item-total score correlations ranged from 0.408 to 0.660. Exploratory factor analysis revealed a four-factor structure that explained 57.730% of the total variance, with item loadings ranging from 0.380 to 0.863. Confirmatory factor analysis supported the four-factor structure, with factor loadings ranging from 0.52 to 0.87 and acceptable fit indices: χ2/df=1.461, goodness-of-fit index=0.901, comparative fit index=0.939, incremental fit index=0.941, Tucker-Lewis index=0.926, and root mean square error of approximation=0.066.
Conclusion:
The validity and reliability analyses revealed that the scale is a valid and reliable measure in Turkish culture.
