Insights
A new Teacher's Evaluation of Neurodevelopmental Delays (TEDD) tool was developed and validated for early detection of developmental delays in children in India. The tool shows good content validity and is ready for further feasibility and reliability testing.
Area of Science:
- Child Development
- Neurodevelopmental Disorders
- Educational Psychology
Background:
- Early detection of developmental delays is crucial for children's potential.
- Current diagnostic standards like DSM-V may not fully address cultural contexts in low- and middle-income countries.
- There is a need for culturally relevant tools for identifying neurodevelopmental delays in India.
Purpose of the Study:
- To develop and validate the Teacher's Evaluation of Neurodevelopmental Delays (TEDD) tool.
- To align the TEDD tool with DSM-V criteria for neurodevelopmental disorders.
- To synchronize the tool with ICD-10 and ECCE/NYCE developmental milestones, using behavioral terms.
Main Methods:
- Literature review for tool development.
- Modified Delphi technique for content validation.
- Expert consensus from nine professionals (doctors, psychologists, educators, therapists).
Main Results:
- A 28-item TEDD tool was finalized.
- The retained items are suitable for the Indian context.
- The tool demonstrated good content validity.
Conclusions:
- The TEDD tool possesses good content validity for identifying neurodevelopmental delays in Indian children.
- Future research will focus on assessing the tool's feasibility and reliability.
- This validated tool can aid in early identification and intervention for developmental delays.
Background:
Early detection of developmental delays in children can significantly help them realise their full potential. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), is the system in use at the moment to detect neurodevelopmental delays among children in the United States and other Western nations. However, due to cultural differences, there is a pertinent need for a content-validated module in the context of low- and middle-income countries, including India.
Purpose:
The aim of this study was to develop and validate Teacher's Evaluation of Neurodevelopmental Delays (TEDD) tool based on the criterions and definitions of neurodevelopmental disorders as mentioned in DSM-V and then synced with developmental milestones mentioned in International Classification of Diseases, 10th revision (ICD-10) and Early Childhood Care and Education (ECCE)/ New York City Early Education Centre (NYCE) framework, and items were worded in behavioural terms.
Methods:
We did a thorough review of the literature for the development of TEDD tool and used modified Delphi technique to content validate it. Data from nine experts, such as doctors, clinical psychologists, special educators, speech and language and applied behaviour analysis therapist were used for the analysis.
Results:
Analysis resulted into 28 items being retained which can be applied in the Indian context.
Conclusion:
This study has shown good content validity of the TEDD tool. Future studies are being planned to rule the feasibility and reliability of this tool.
