Insights
The Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) offers a practical approach to assessing child development in HIV-infected infants. This method aids in early detection of developmental delays, facilitating timely intervention.
Area of Science:
- Pediatric Development
- Infectious Diseases
- Clinical Assessment Tools
Background:
- The Bayley Scales of Infant Development (BSID) is a standard but time-consuming child development assessment.
- Busy clinics require efficient and accessible developmental screening tools.
- HIV-infected infants may benefit from specialized developmental monitoring.
Purpose of the Study:
- To pilot the Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) for assessing developmental quotients (DQ) in HIV-infected infants.
- To evaluate CAT/CLAMS as a screening tool for early detection of developmental delays in this population.
Main Methods:
- A pilot study involving 16 HIV-infected infants aged 12-34 months.
- Application of the CAT/CLAMS assessment to measure developmental quotient (DQ).
- Comparison of CAT/CLAMS results with established developmental assessment standards.
Main Results:
- All 16 HIV-infected infants in the pilot study scored within the normal range of developmental quotient (DQ).
- The CAT/CLAMS assessment proved feasible for use in this cohort.
- Further longitudinal follow-up is recommended for these children.
Conclusions:
- The CAT/CLAMS is a potentially valuable and efficient tool for screening child development in HIV-infected infants.
- A DQ score below 70 on CAT/CLAMS warrants further evaluation with BSID.
- Early screening facilitates timely intervention programs for developmental delays.
Abstract:
Bayley Scales of Infant Development (BSID) is considered to be a standard test for child development. The test requires experienced evaluator and is time consuming; therefore, it is not easy to apply in busy clinic. The Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) is an easy assessment method that has been demonstrated to correlate with BSID in many studies among normal and developmental delayed children, including in HIV-infected infants. We created a pilot system of CAT/CLAMS assessment applied to 16 HIV-infected infants ages 12-34 months. They were all in the normal range score of developmental quotient (DQ). However, longitudinal follow-up by CAT/CLAMS assessment is needed in these HIV-infected children. When DQ score is below 70 (assuming to be delayed development), the child should be evaluated by BSID. In this way delayed development can be screened easily and early developmental stimulation program can be implemented appropriately.

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,...
