Insights
The Taiwan Birth Cohort Study developed efficient developmental screening scales for infants. These scales demonstrate validity and reliability for early identification of developmental risks in clinical settings.
Area of Science:
- Child Development
- Developmental Psychology
- Public Health
Background:
- Early developmental screening is crucial for identifying potential risks and enabling timely interventions.
- Existing screening tools may lack efficiency or suitability for widespread clinical and community use.
- The Taiwan Birth Cohort Study aimed to address these limitations by creating a novel screening instrument.
Purpose of the Study:
- To develop and validate an efficient developmental screening instrument for infants.
- To assess the reliability and validity of the Taiwan Birth Cohort Study (TBCS) scales.
- To evaluate the TBCS scales' concurrent and predictive validity against established measures.
Main Methods:
- Utilized random sampling to select two groups of infants (n=1747 for pilot, n=100 for concurrent validity).
- Assessed gross motor, fine motor, language/communication, and social/self-care abilities.
- Employed structural equation modeling to test concurrent validity with the Bayley Scale of Infant Development.
Main Results:
- The TBCS scales demonstrated significant correlations with corresponding dimensions of the Bayley Scale of Infant Development.
- Predictive validity was supported by correlations of 0.29 (motor index) and 0.31 (language social index) between 6- and 18-month assessments.
- The scales met criteria for developmental norms, predictive validity, and identification of relative risk.
Conclusions:
- The TBCS 6- and 18-month scales are valid and reliable developmental screening instruments.
- The self-report checklist format is economical and efficient for clinical and community settings.
- These scales can effectively identify infants at risk for developmental delays, facilitating early intervention.
Aim:
To develop an efficient developmental screening instrument for interview purposes.
Methods:
Using random sampling, two groups of babies were selected: The pilot group of 1747 babies was selected for testing of reliability and validity. Another group of 100 babies was selected for testing of the concurrent validity with the second edition of the Bayley Scale of Infant Development. The Taiwan Birth Cohort Study scales include four developmental dimensions: gross motor, fine motor, language/communication (language) and social/self-care ability (social).
Results:
In testing the concurrent validity, the structural equation model showed that Taiwan Birth Cohort Study dimensions correlated with the Bayley Scale of Infant Development dimensions. In testing the predictive validity of the Taiwan Birth Cohort Study, the correlation between the 6- and 18-month results of the motor index was 0.29, and the language social index was 0.31.
Conclusion:
The Taiwan Birth Cohort Study 6- and 18-month scales fulfill the criteria of developmental norm, predictive validity, validity and identification of relative risk for screening instruments. As a self-report checklist, it is economical and efficient, thus, it can be utilized in clinical and community settings.

Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
