Developmental changes of institutionalized mentally retarded children: a semilongitudinal study
American Journal of Mental Deficiency
|November 1, 1982
Summary
Intellectual disability in institutionalized children correlates with developmental behaviors. This study tracked 200 children, finding a linear relationship between intelligence and development from ages 7-20.
Area of Science:
- Developmental Psychology
- Clinical Psychology
- Pediatrics
Background:
- Institutionalized children with intellectual disabilities often exhibit varied developmental trajectories.
- Understanding these trajectories is crucial for predicting future outcomes and tailoring interventions.
Purpose of the Study:
- To analyze developmental curves in institutionalized children with intellectual disabilities.
- To investigate the relationship between intelligence levels and developmental behaviors.
- To examine sex-based differences in developmental patterns.
Main Methods:
- Collected Developmental Record ratings for 200 institutionalized children over 3 years.
- Utilized principal components analysis for data input.
- Generated semilongitudinal developmental curves stratified by intellectual disability level and sex.
Main Results:
- Intelligence differences are linked to variations in developmental behaviors.
- A primarily linear relationship exists between intelligence and development from ages 7 to 20.
- Sex differences in developmental patterns were found to be minimal.
Conclusions:
- Developmental Record ratings can predict later attainments in institutionalized children.
- The findings offer insights into the developmental progression of children with intellectual disabilities.
- Intervention strategies can be informed by understanding the link between intelligence and developmental behaviors.
